The Rhizobium and calcium fertilizer application to peanut plant in dry land

One of the main problems of peanut planting in dry land is a lack of nitrogen and calcium availability. Efforts to increase the nitrogen and calcium availability for peanut farming in dry land is needed and one possible approach is by application of Rhizobium and calcium fertilizers. This research was conducted to determine the effect of the application of Rhizobium (Nodulin) and calcium fertilizers on growth and yield of peanut plants in dry land. Two experiments were conducted, one in a greenhouse using a completely randomized design and another experiment in the field using a randomized block design. The treatments were with the application of Nodulin, without Nodulin, with calcium fertilizer and without calcium fertilizer. The results showed that the application of calcium and Nodulin was able to increase the number of root nodules and peanut growth. Nodulin and calcium fertilizers increased the dry pod weight of 2.177 g per 6 m2 or 3.7 tons.ha-1. The application of Nodulin and calcium was also able to increase the nitrogen and calcium content of leaf tissue up to 18.9% and 20.9%, respectively.

Defisit Air Pada Berbagai Fase Pertumbuhan dan Pengaruhnya Terhadap Karakter Kuantitatif Beberapa Genotipe Kacang Tanah

This study aims to determine the effect of water deficit at various phases of plant growth on the quantitative characters of several peanut genotypes. This study used a completely randomized design-split plot design. The water deficit consisted of 6 treatments: d0 = no water deficit, d1 = water deficit from germination to harvest, d2 = water deficit from germination to age 25 days after planting (dap) (vegetative phase), d3 = water deficit from age 26 to 50 dap (flowering phase to pod formation), d4 = water deficit from age 51 dap to 75 dap (seed filling phase), and d5 = water deficit from age 75 dap to 100 dap (seed ripening phase until harvest). The peanut genotype used consisted of 10 genotypes. The results showed that water deficit in various phases of plant growth resulted in different quantitative characters in several peanut genotypes. Genotype G3T4 produced heaviest dry pod weight of 12.7 g plant-1 in water deficit from germination to harvest. Genotype G200-I produced heaviest dry pod weight of 11.5 g per plant-1 in water deficit in the vegetative phase. Genotype G3T4 produced heaviest dry pod weight of 13.3 g per plant in water deficit the generative phase. Genotype G300-II produced heaviest the dry pod weight of 11.7 g per plant-1 in the water deficit of the seed filling phase. Genotypes G2D2, G2T3 and G200-I produced the heaviest dry pod weight of 11.0 g per plant-1 in the water deficit of the seed ripening phase.

Cold Stress during Flowering Alters Plant Structure, Yield and Seed Quality of Different Soybean Genotypes

The objective of the study was to evaluate the effect of cold stress at flowering stage on plant structure, yield and chemical composition of seeds of 15 soybean cultivars. The study was conducted in 2019–2020, using the complete randomization method, in three replications. Fifteen soybean cultivars belonging to three maturity groups: early (EC), middle-early (MC) and late (LC) cultivars were included. Weekly cold stress (17/13 °C day/night) was applied at plant flowering stage. In the control treatment, plants were kept under natural conditions (24/17 °C day/night). Our research showed that cold stress negatively influenced the elements of plant structure: height, number of nodes, stem dry mass, number and weight of pods, number and weight of seeds per plant, as well as yield of soybean seeds, reducing it on average by 24%, as compared to the control treatment. The highest yield decrease was found in LC cultivars (31.2%), while a smaller and similar one in EC and MC cultivars (by 19.7 and 20.1%, respectively). Significant varietal differences were found for plant biometric traits and seed yield. EC cultivars had the lowest set first pod, as well as the lowest number of nodes, number of pods and seeds, pod and seed weight per plant, and seed yield. MC cultivars had the highest set first pod, and the smallest stem DM and seed yield average by 29.2% higher compared to EC cultivars. LC cultivars had the highest stem DM, number of pods and seeds, and pod and seed weight per plant compared to the other cultivar groups, and yield by 22.8% higher compared to EC cultivars. The experimental factors significantly affected crude protein, crude fat, and crude ash content, while they did not differentiate water-soluble carbohydrate and crude fiber content. Cold stress at the flowering stage caused a significant increase in protein content (by 4.1% on average) and ash content (by 3.8%) and a decrease in fat concentration (by 6.9%) in soybean seeds. Differences in nutrient content among cultivars were a genetic trait not related to cultivar maturity.

Phosphorus Mobilizing Capacity of Selected Grain Legumes Grown Under Phosphorus-Deficient Conditions

Compared with other crops, legumes have superior ability to mobilize part of non-labile phosphorus (P) into labile/available forms. We explored the P-mobilization potential of selected grain legumes and its influence on growth, P uptake, and yield under P-deficient conditions. A pot experiment was carried out in a greenhouse with soybean (<em>Glycine max </em>L.), cowpea (<em>Vigna</em> <em>unguiculata </em>L.), green gram (<em>Vigna radiata </em>L.), and black gram (<em>Vigna mungo </em>L.) with two P fertilizer applications; without (Pdeficient) and with (P-sufficient) Department of Agriculture recommended rates of triple super phosphate. Each crop was harvested at maturity and the bulk and rhizosphere soils were collected to quantify different P fractions using Hedley’s sequential fractionation. Dry weight and P accumulation in different plant organs, <em>i.e. </em>roots, stems, leaves, and pods, were measured. Most plant organs maintained similar dry weight and tissue-P concentration irrespective of the P levels applied. All crops reduced their total plant-P uptake under P-deficient conditions. However, this did not make any change in either pod dry weight or P concentration of pods. Soybean and mung bean had a greater P accumulation compared to cowpea and black gram under both P levels. In contrast, cowpea and black gram showed improved P use efficiency (PUE) than other two legumes. Available P concentration (NaHCO3-P) in rhizosphere soil is greater than that in bulk soil in soybean and cowpea whereas the rhizosphere NaHCO3-P content in mung bean was greatly decreased compared to that of bulk soil when the crop was cultivated in P-deficient soil. The concentration of non-labile P fraction in rhizosphere of all grain legumes were significantly low compared to that of the bulk soil. Results suggest that selected grain legumes could be cultivated in P-deficient soil as they can adapt either through enhancing P uptake or increasing PUE.

​Efficiency of Biocomposted Agroindustrial Wastes and Their Response in the Growth and Yield of Vigna unguiculata (L.) Walp

Background: Agroindustrial by-products of cocoa shell and jack fruit peels generally considered as organic waste have almost no economic value and create a big problem in disposal time. A significant amount of biocomposted cocoa shell and jack fruit peel waste is used as organic manure that enhances growth in Vigna unguiculata (L.) Walp. Methods: This research work was conducted in the period of 2019 in the Department of Botany, Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore, Tamil Nadu (India). A large amount of cocoa shell and jack fruit peel waste was used for the biocompost preparation using Pleurotus eous, Pleurotus florida spawns and Eudrilus eugeniae. After 90 days, biocompost were taken and sieved used as manure for plant study. Eight different treatments were carried out for the cultivation of Cowpea. Plant samples at various stages (25, 35 and 45 DAS) were analyzed for shoot and root length, number of leaves, flowers, nodules /plant, fresh weight and dry weight of plant. On 65th day yield parameters like number of pods/plant, length of the pod, number of seeds/pod, weight of seeds/pods, pod fresh weight and pod dry weight were analyzed. Result: The experimental results showed that the application T8 (Raw jackfruit peel + 10 g Pleurotus eous + 10 g Pleurotus florida + Eudrilus eugeniae 5 t/ha-1) recorded maximum root (20.63 cm, 32.73 cm and 39.23 cm), shoot length (70.73 cm, 167.50 cm and 175.83 cm), number of leaves/plant (26.46 cm, 33.53 cm and 37.50 cm), number of flowers/plant (12), number of nodules (14, 21.20 and 11.34), fresh weight (10.076 g, 12.146 g and 14.047 g) and dry weight (1.744 g, 1.854 g and 2.827 g) are closely followed by T4 (Raw cocoa shell+ 10 g Pleurotus eous + 10 g Pleurotus florida + Eudrilus eugeniae 5 t/ha-1). A significant increase in the yield parameters such as number of pods/plant (21), length of pod (16.50 cm), number of seeds/pod (20), weight of seed/pod (1.68 g), fresh weight (5.711 g) and dry weight of pod (2.398 g) was observed in treatment T8 as compared to the other treatments (T1, T2, T3, T5, T6 and T7) and control respectively.

Physiological and Expressional Regulation on Photosynthesis, Starch and Sucrose Metabolism Response to Waterlogging Stress in Peanut.

Waterlogging has negative effects on crop yield. Physiological and transcriptome data of two peanut cultivars [Zhongkaihua 1 (ZKH 1) and Huayu 39 (HY 39)] were studied under normal water supply and waterlogging stress for 5 or 10 days at the flowering stage. The results showed that the main stem height, the number of lateral branches, lateral branch length, and the stem diameter increased under waterlogging stress, followed by an increase in dry matter accumulation, which was correlated with the increase in the soil and plant analysis development (SPAD) and net photosynthetic rate (Pn) and the upregulation of genes related to porphyrin and chlorophyll metabolism and photosynthesis. However, the imbalance of the source–sink relationship under waterlogging was the main cause of yield loss, and waterlogging caused an increase in the sucrose and soluble sugar contents and a decrease in the starch content; it also decreased the activities of sucrose synthetase (SS) and sucrose phosphate synthetase (SPS), which may be due to the changes in the expression of genes related to starch and sucrose metabolism. However, the imbalance of the source–sink relationship led to the accumulation of photosynthate in the stems and leaves, which resulted in the decrease of the ratio of pod dry weight to total dry weight (PDW/TDW) and yield. Compared with ZKH 1, the PDW of HY 39 decreased more probably because more photosynthate accumulated in the stem and leaves of HY 39 and could not be effectively transported to the pod.

Application of dry powders of six plant species, as soil amendments, for controlling Fusarium solani and Meloidogyne incognita on pea in pots

BackgroundApplication of organic amendments could improve soil properties as well as controlling of soil-borne pathogens. Soil amendments with dry powders of six plant species materials, i.e. caraway seeds, fennel seeds, garlic gloves, onion bulbs, pomegranate peel and spearmint leaves were separately applied for controlling Fusarium solani and Meloidogyne incognita on pea plants in pots. The control is untreated check pots for Fusarium solani and Meloidogyne incognita.ResultsThe dry powder of pomegranate peel (as the rate of 10 g/1 kg soil)highly reduced the Fusarium- disease assessments (pre-emergence and post-emergence damping-off and root-rot diseases incidence), followed by spearmint leaves, caraway seeds, fennel seeds, garlic gloves and onion bulbs, respectively. The tested dry powder of plant species showed the nematicidal activity on M. incognita criteria, i.e. second juvenile (J2) in soil and roots as well as galls and egg-masses in roots of pea. The spearmint leaves, onion bulbs and fennel seeds highly reduced the J2 in soil and roots as well as galls and egg-masses. The pea plant growth parameters i.e. length of shoot, fresh & dry weights of shoot and fresh weight of roots, yield parameters, i.e. fresh and dry weight of pea pod and pod parameters as well as Rhizobium nodules number were increased in pea plants with reducing infestation with F. solani and M. incognita.ConclusionsSoil amendments with dry powders of six plant species materials were used in this study reduced F. solani and M. incognita and improved pea plants

Organic Waste as Fertilizer to Increase the Number of Peanuts (Arachis hypogaea L.) Flowers

Peanut has high economic value and a significant role in food needs. the national food supply needs for peanuts to date have not been sufficient. This study aimed to determine the effect of organic waste which in this case is mushroom baglog compost and sheep manure on the flowers and pods of peanuts. The study was conducted on March-July 2018 in Subang district using the simple experimental plot method and group-randomized factorial design with two factors with each treatment done triplicate. The first factor is the baglog compost (soil without baglog compost, 90 g/plants, 120 gr/plants); the second factor is sheep manure dose (without sheep fertilizer, 90 gr/ plants, 120 gr/plants). The results showed that the application of baglog compost and sheep manure fertilizer at concentrations of 90 g and 120 g, respectively increased the number of flowers and potential pods. Moreover, Sheep manure fertilizer at a concentration of 120 g/plant, increased the dry weight of pods, seed, and 100 seeds even though was not significant.

Physiological Properties and Molecular Regulation in Different Edamame Cultivars under Drought Stress

Edamame (Glycine max (L.) Merr.) is an important economic crop worldwide and is a good source of protein and nutrients. Kaohsiung No. 9 (KH9), Kaohsiung No. 11 (KH11), and Xiang-Ji (XJ) are three major edamame cultivars planted in Taiwan. Edamame has high water requirements in all development stages. Insufficient irrigation causes aborted blossoms, small pods, and shriveled beans, thus greatly reducing the yield. We examined the three aforementioned cultivars in drought conditions during the blooming period. The results revealed that drought stress decreased the yield in all three cultivars; however, XJ and KH11 showed better drought resistant ability than KH9 did. The reduction of the qualification rate and the dry weight of qualified pods by drought stress in XJ, KH9 and KH11 was 23%, 33%, 21% and 32%, 62%, and 44%, respectively. The quantitative reverse-transcription polymerase chain reaction results indicated that genes involved in the abscisic acid (ABA) biosynthesis, ABA-dependent, and ABA-independent pathways were upregulated by drought stress in KH11, which may explain why KH11 produced higher yields than KH9 after drought treatment. We determined that drought-related signaling transduction differed among these edamame cultivars, resulting in different drought tolerance.

Estimation of Heritability of Several Genotype of Soil (Arachis Hypogaea L.) and Tolerance Test of Shade and Drought Stress

This study aims to determine the heritability estimation of several peanut genotypes and to test tolerance to shade and drought stress. The research was carried out in 3 stages, the first stage from May to July 2019 in Sigerongan village, Lingsar District, West Lombok Regency, the second phase from August to October 2019 in Sigerongan village, Lingsar District, West Lombok Regency, and the third stage from July to September 2020 in Nyiurlembang village, Narmada District, West Lombok Regency, West Nusa Tenggara. The experimental design used in estimating heritability was a randomized block design (RAK) consisting of 20 peanut genotypes, namely G2T5, G3D6, G2D2, G5-UII, G300-II, G2T3, G11-UI, G3T4, G200-I, and G12. -UI, G2T1, G2D7, G3T10, G3D8, G7-UII, G7-UIII, G3T7, G16-UI, G7-UI and G2D3. Tolerance test of peanut genotypes to shade and drought stress used a Randomized Block Design (RBD) with a Split Plot Design. The results showed that the genetic diversity value of peanut genotypes against the tested parameters showed that all peanut genotypes were ineffective for further tests on the parameters of plant height, number of leaves and number of branches, while the parameters of the number of filled pods and dry weight of pods all genotypes showed moderate criteria which means that it is effective for further selection. Shade treatment was more influential than treatment without shade. The parameters of pod dry weight and number of filled pods showed a significant difference between the two. Genotypes sensitive to shade stress are G2T5, G3D6, G2T3, G200-I, G2T1, G2D7, G3D8, G7-UII, TAKAR, G3T7, mildly tolerant genotypes, namely G2D2, G5-UII, G300-II, G11-UI, G3T4, G12-UI, G3T10, G7-UI, and G2D3 and the shade tolerant is G16-UI. Plant genotypes that were sensitive (P) to drought stress were G2T5, G3D6, G2D2, G5-UII, G2T3, G11-UI, and G3T4. And the genotypes that are somewhat tolerant are G200-I and G12-UI. Meanwhile, the drought tolerant genotype was G300-II.

The field study was carried out in the grey degraded soil of Tri Ton town during Winter-Spring and Summer-Autumn crop of 2019- 2020. The field experiment was carried out by four treatments and four replications. Four treatments of Winter-Spring crop: The control treatment applied NPK (100 kgUrea + 556 kgP2O5 + 100kg KCl); (NT2): application of NPK, lime with Rhizobium inoculation; (NT3): NPK, cow manure and Rhizobium inoculation; (NT4):NPK, cow manure and lime with Rhizobium. Four treatments of Summer-Autumn cropwere carried on the prior experiment (Winter-Spring crop).However, treatments did not apply to cow manure, lime and Rhizobium(only NPK).The maximum plant biomass (168 g), number of nodule (92.1), fresh and dry weight of fill pods (61.4 and 37.6 g, respectively), fresh and dry weight of empty pods (2.07 and 1.19 g ), weight of dry nodules (0.83 g ) per plant, yield (6.12 ton ha-1), protein and oil in seeds (26.1 and 50.1%, respectively) were observed in cow manure and lime applied with Rhizobium inoculated treatments. All the parameters of growth and yield showed best result for application of lime and cow manure with synthetic Rhizobium inoculation of seeds. Cow manure has significantlyincreased the yield of peanut in the next crops. The results from our two crops of study showed that co-application of NPK, cow manure, lime and Rhizobium inoculation always increased field capacity in both crops.

Advanced Yield Trial for Various Peanut Lines (Arachis hypogaea L.) at Sodonghilir, Tasikmalaya, West Java, Indonesia

This study aims to evaluate yield and yield components in several peanut lines planted in West Java, Indonesia. The genetic materials tested involved 21 genotypes consisting of 18 potential peanut lines (G100, G133, G142, G144, G199, G205, G209, G21, G234, G237, G33, G37, G41, G53, G54, G76, G84, G99) from a selection of 5 biparental population (GWS79A1/”Zebra”, “Jerapah”/GWS79A1, “Zebra”/GWS79A1, GWS79A1/”Jerapah”, “Zebra”/GWS18A1) and 3 comparative varieties (“Gajah”, “Sima”, and “Zebra”) as controls. Results showed that various genotypes have significant effects on plant height (at 9 and 10 WAP), number of branches (at 4, 10, and 12 WAP), flowering age, and harvest age. Some potential lines showed ideal characters expected of a high quality peanut plant. Based on characters such as harvest age, dry pod weight, and productivity, G100, G41, G21, G205, and G84 can be considered the best potential lines. These lines demonstrated high heritability values including characters classified as high category such as plant height, number of branches, age of flowering, age of harvest, harvest index, wet stover weight, fresh pod weight, number of filled pods, number of empty pods, number of filled pods, and weight of 100 seeds. Additionally, these lines also show high productivity, a character classified in the medium category.

Shade stress in various growth phases of peanut genotypes and its effect on agronomic characters and chlorophyll content

Shading stress during plant growth is one of the factors that might decrease the peanut crop productivity. The growth phase of the peanut genotypes has different responses to shade stress. This research aimed to study the effect of shade stress in various growth phases on agronomic character and chlorophyll content of peanut genotypes. Shade stress was regulated in six conditions: no shade, shade from planting to harvest, shade from planting until 25 days after planting (dap) (vegetative phase), shade from 26 to 50 dap (flowering phase to pods formation), shade from 51 to 75 dap (seed filling phase), and shade from 75 to 100 dap (the ripening phase of the seeds to harvest). The shade was carried out using paranet which holds 35% of the sun’s rays. The genotypes used were F3 generation plants from crosses (G200-I and G300-II x cv.Domba, Takar 1, Bison). The results showed that there were no significant differences in the interactions between shades in various growth phases and genotypes for agronomic traits, but there were significantly different interactions on the content of chlorophyll-a and total chlorophyll. All 12 peanut genotypes tended to produce more chlorophyll-a and total chlorophyll in shade treatment from planting to harvest. Shade at various plant growth phases had a significant effect on agronomic characters. The shade given from planting beginning to harvest produced the lowest dry pod weight (12.9 g/plant) or yield decreased to 23.7% compared to peanut grown without shading. The genotypes significantly affected agronomic traits and g6 genotype (G200-I x cv.Domba)7 produced the heaviest dry pod weight 17.2 g/plant.

Effect of Sowing Dates and Gibberellin Foliar Spraying on Growth of Soybean

Two field experiments were conducted at Agricultural Research Farm of the Faculty of Agriculture, Benha University, Egypt, during two growing seasons of 2018 and 2019 to study the effect of sowing dates (May 5, May 20 and June 3), three gibberellinconcentrations (0, 50 and 100 ppm) and their interaction on growth attributes of soybean (Giza 111 cultivar). The outcome of this study indicated that early planting date (May 5) improved plant height and No. of pods (at 70 and 90 days after planting) and improved the absolute growth rate (AGR) and net assimilation rate (NAR) relatively to the other treatments (p < 0.05). Furthermore, applying GA3 (100 ppm) recorded the maximal values of the growth parameters, except RGR and chlorophyll content which were at 0 and 50 ppm. At 90 DAP, the tallest plants (120.54 cm), No. of leaves/plant (34.11), No. of pods/plant (55.09), and dry weight of stem (21.67 g), pods (23.55 g) and plant (68.75 g) were obtained following the combined effect of May, 5 planting date and GA3 at 100 ppm.Whereas the interaction between the early planting date and GA3 at 50 ppm produced the maximum values of the AGR (1.074g/day), RGR (0.019 g/day) and NAR (1.074 g/day).

Tahap Awal Seleksi Galur Murni Ercis (Pisum sativum L.) Populasi Lokal Boyolali dan Temanggung Berdasarkan Karakteristik Fisik Biji

Pea (Pisum sativum L.) is a nutritious and high-value vegetable. Plant cultivation and the selection of superior cultivars are two ways to increase pea production. One technique of plant breeding for improved varieties is to get some genotipes from local populations. The genetic potential of the pure line selection based on the physical features of the seeds is indicated agronomic and morphological variability. The purpose of this study is to investigate agronomic characteristics and heritability of pea lines developed based on physical seed selection in local population. This research used randomized block desig) consist 22 lines based on seed characteristics selection, which are 12 local lines from Boyolali and 10 local lines from Temanggung as a treatment and repeated three times. Research has been carried out on January 2019 to April 2019 and located at Abdulrachman Saleh Air Force Base Agricultural Experimental Green House, Malang. Agronomics characters that have medium variability are flowering day, length from stem to first pod, length of leaf, length between first and second pods, length of tendrils, length of stem, number of branches, number of bracts, number of seeds per plant, weight of dry pods, weight of dry seeds per pod, length of dry seeds, width of dry seeds, and weight of dry seeds per plant. The high heritability are found inflowering day, day to harvesting dry pods, and length of nodes.

Aqueous seed extracts of Jimson weed (Datura stramonium L.) stimulate morpho-agronomic attributes in selected soybean [Glycine max (L.) Merr.] varieties

Datura stramonium (L.) contains allelochemicals capable of affecting agro-morphological traits in plants. Thus, field experiment was carried out at Upper Niger River Basin Development Authority, Minna, Nigeria to examine the effects of different concentrations [25%, 50% and 100% and 0% (control)] of D. stramonium aqueous seed extracts on agro-morphological attributes of two soybean varieties (‘TG x 2018-5E’ and ‘TG x 2022-4E’), obtained from International Institute of Tropical Agriculture, Ibadan. Dry seeds of the soybean were pre-soaked in the Datura seed extracts for two hours before planting in a complete randomized block design (CRBD) with three replicates each. Data obtained were subjected to analysis of variance (ANOVA). At maturity, D. stramonium seed extracts significantly (P ≤ 0.05) increased plant height (38.37 cm) and length of petiole (2.93 cm) for ‘TG x 2018-5E’ at 100% concentration. Significantly highest plant height (29.20 cm) and number of branches (17.00) were enhanced in ‘TG x 2022-4E’ at 50% concentration. Both ‘TG x 2018-5E’ and ‘TG x 2022-4E’ leaf areas were significantly highest (23.11 cm2 and 28.41 cm2, respectively) at 100% concentration. Yield attributes such as number of seeds per plant, weight of fresh and dry pods per plant for both ‘TG x 2018-5E’ (3.33, 1.60 and 1.32, respectively) and ‘TG x 2022-4E’ (3.00, 0.60 and 0.26, respectively) were significantly stimulated in 50% concentration while number of pods per plant was significantly highest for ‘TG x 2018-5E’ and ‘TG x 2022- 4E’ (3.33 and 3.00, respectively) in 100% concentration. On these premises higher concentrations (50% and 100%) of D. stramonium seed extracts support better morphological growth and yield characters in soybean varieties.

The Effect of Inoculum Type and Mycorrhiza Dosage on Growth and Production of Mung Bean Vigna Radiata L.

Mung bean (Vigna radiata L.) is the third most essential legume crop commodity after soybeans and peanuts. Mung bean production faced problems of nutrient-poor land and soil texture that does not support soybean growth. The solution to overcome these obstacles is the application of mycorrhizae in nutrient-poor soils. This study aimed to determine the effect of various inoculums and mycorrhizal doses on growth and production in mung beans. This study used a Completely Randomized Design with nine treatments and three replications. The research included mycorrhizal inoculation with various treatments, as well as observations with variable plant height, plant biomass, number of pods, wet weight and dry weight of pods, the weight of 50 wet and dry seeds, mycorrhizal infection in roots, and number of spores in 100 gr of soil. The data were analyzed by SPSS 15.0 program for ANOVA. The results indicated that granular (30 gr) had the highest plant height of (41.33 cm), crown weight (30.69 gr), number of pods, wet and dry pod weight is 13.66, 9.84 gr, and 8.86 gr, respectively, 50 kg of wet and dry weight (3.82 and 3.20) and the highest effect on the number of spores at 29.33. The 30 gr tablets treatment showed the highest results on root weight (22.98 gr), while the 30 gr mixture showed the highest results on the percentage of infection (73.33%).

The Effect of Various Water Content Levels and The Application of Several Brown Algae (Sargassum polycystum) Composts in Increasing The Production of Soybean (Glycine max L.) Plant.

The purpose of this research was to study whether the application of brown algae (Sargassum polycystum) compost can increase productivity and reduce the amount of water needed by soybean (Glycine max L.) plants. This research was conducted from July 2017 to September 2017 at Pasar 1 Tanjung Sari land, Medan Selayang sub-district. The research design used was Factorial Randomized Group Design with two factors. The first factor was watering with various levels of water content, with K1 = 100% field capacity, K2 = 75% field capacity, K3 = 50% field capacity, K4 = 25% field capacity, the second factor was the application of brown algae compost consisting of G0 = 0 gram/plot, G1 = 1,125 kg/plot, G2 = 2,250 kg/plot, G3 = 3,375 kg/plot. The observed parameters were plant height, stem diameter, number of leaves, pod wet weight, canopy wet weight, pod dry weight, canopy dry weight, 1000 seed weight, and seed weight. The results showed that the effect of various watering levels of water content and the application of brown algae compost had a significant effect on plant height parameters at 4 Weeks After Planting, brown algae had a significant effect on canopy wet weight per plot and canopy weight per sample. The cause of soybean production not reaching production of 3 tons/ha was the effect of boron.

PRODUCTIVITY OF IRRIGATED PEANUT PLANTS UNDER PULSE AND CONTINUOUS DRIPPING IRRIGATION WITH BRACKISH WATER1 2

ABSTRACT Pulse irrigation may be more advantageous for peanut crops than continuous irrigation, when using brackish water. However, studies on pulse irrigation with brackish water considering the environmental conditions of the Northeast region of Brazil using are incipient. Therefore, the objective of this study was to evaluate the effect of using brackish water for pulse and continuous dripping irrigations on the grain yield and production characteristics of peanut (Arachis hypogaea L.) crops. A completely randomized block design with four repetitions was used, in a 6*2 factorial arrangement consisted of six electrical conductivities of the irrigation water (EC; 0.2, 1.6, 2.8, 4.0, 5.2, and 6.4 dS m-1) set by adding NaCl to the irrigation water, which originally had 0.2 dS m-1, until reaching the respective EC; and two irrigation methods (pulse and continuous). The evaluated variables were fresh and dry weights of shoot, 10 grains, pods, grains, and production; number of pods and grains; and percentages of empty pods (EP%) and perfect grains (PG%). The addition of salt to the irrigation water negatively affected all variables studied, except for EP% and PG%. The lowest EP% were found for the pulse irrigation, which increased the pod and grain yields, regardless of the EC of the irrigation water. Under the conditions of the present study, the use of brackish waters with electrical conductivities of up to 2.98 dS m-1 is viable for peanut production.
