Intercropping pulses with mulberry on sericulture productivity and profitability

This study was conducted during 2020-2021 in three locations viz: research field of Bangladesh Sericulture Research and Training Institute (BSRTI), Rajshahi, five farmer’s fields of Bholahat, Chapainawabganj and Paba, Rajshahi to evaluate the effect of growing pulses intercrops with mulberry productivity, silkworm rearing, soil properties and economy. The experiments were laid out in RCBD methods with three replications and six treatments.The growth and yield parameters of mulberry like average branch number/plant, total leaf number/plant, total branches length/plant, nodes/ meter/plant, length of longest shoot, leaf present/branch, 10 leaves area, total leaf weight/plant, total shoots weight/plant and total leaf yield were higher in T4. Leaf quality viz: moisture content, total chlorophyll, crude protein, total sugar, reducing sugar and mineral in percentage (%) were significantly greater in T4. The cocoon attributes like weight of 15 larvae, single cocoon weight, shell weight, cocoon shell ratio, highest filament length, renditta and cocoon productivity/100 dfls were better also in T4 (54.68, 33.75, 0.27, 21.98, 990.41, 10.29 and 72.67) as compared to control (51.23, 31.21,0.19, 19.05, 962.96, 12.44, 69.07) respectively. Chickpea as an intercrop was given higher benefit: cost (1.30) due to increased soil fertility, higher leaf yield (except control), leaf quality, cocoon yield and additional income as compared with other intercrops (1.14, 1.07, 1.01, 0.93 and 0.86 for pea, grasspea, mugbean, sole mulberry and lentil respectively).

Identification of Alternatives to Landraces of Kale (Brassica oleracea Group Acephala) for Off-season Cultivation and Seed-to-seed Production in Kashmir Valley

Aim: To characterize kale (Brassica oleracea group Acephala) germplasm well adapted for July to December cropping season in Kashmir valley for suitability for year round cultivation with respect to leaf yield (t/ha).
 Study Design: Random Complete Block Design with two replications.
 Place and duration of study: The study was done in Vegetable Experimental Field of ICAR-Central Institute of Temperate Horticulture, Srinagar, Jammu and Kashmir, India from 2017-18 to 2018-19.
 Methodology: The germplasm comprising breeding lines and landraces as checks was sown and then transplanted at different times of the year to evaluate for leaf yield potential at edible maturity stage. The final yield for each genotype was calculated by summing up all pickings. Critical differences among genotypes for total leaf yield were calculated from ANOVA using OPSTAT online tool for one factor analysis.
 Results: Considering the average performance of two years in terms of leaf yield in tone per hectare, NW-Saag-1 (24.77, 25.08 and 25.01), CITH-KC-16 (28.79, 26.74 and 11.20) and CITH-KC-18 (24.25, 24.14 and 11.91) were found to yield significantly better than local checks Khanyari (7.77, 8.47 and 21.31) and GM Dari (10.36, 15.98 and 9.65) when transplanted in May, June and July, respectively. Months of April, May, June, July and August were most conducive for normal nursery production followed by May to September transplanting to get economical yields. January sowing of selected genotypes in polyhouse along with added protection from polysheet resulted in vigorous and healthy seedlings. Their transplanting in the second fortnight of March resulted only in short vegetative phase of the crop followed by bolting and seed production. However, this approach came out as an opportunity to produce seed in 7 months (January to July) compared to 1 year normally taken in farmer adopted seed production method.
 Conclusion: NW-Saag-1, CITH-KC-16 and CITH-KC-18 lines yielded significantly higher than local landrace kales for offseason cultivation and seed-to-seed technique of seed production is an economic and short method of kale seed production in Kashmir valley.

Products of cassava leaves and cutcherry leaves from various compositions of intercropping pattern

AbstractThe experiment of intercropping cultivation of cassava and cutcherry plants to harvest the leaves that was fertilized organically. The purpose of this experiment was to determine the effect of organic fertilizer on the total leaf yield of each plant, the efficiency of the land area and the efficiency of the time span of its cultivation. The experiment was carried out at the Practical Garden, Faculty of Agriculture, Universitas Pembangunan Nasional “Veteran” Yogyakarta, Wedomartani, Yogyakarta 55584 from September 2020 to January 2021, altitude 110 m above sea level, soil type Regosol. The research method was divided plot design with two treatments and repeated three times. The main plots consisted of organic fertilization with manure at a dose of 30 t/ha (P1), 40 t/ha (P2) and 50 t/ha (P3). The sub-plots were intercropped with a composition of (25% cassava + 100% cutcherry )/S1; (50% cassava + 100% cutcherry)/S2; (75% cassava + 100% cutcherry)/S3; (100% cassava + 0% cutcherry)/S0; and (0% cassava + 100% cutcherry)/K0. Observational data then calculated by analysis of variance.. The results showed that the dose of manure had no significant effect, but the intercropping pattern had a significant effect on leaf production. The highest yield of cassava leaves was in the intercropping pattern S3, although it was not significantly different from the intercropping pattern S2, while the yield of cutcherry leaves was almost the same in all intercropping patterns. The best intercropping pattern is the composition of (75% cassava + 100% cutcherry)/S3.

Eight samples of representatives of Allium L. genus from Rhizirideum subgenus, Rhizirideum G. Don ex Koch section were studied in the conditions of the Moscow region. The presented study is planned to determine the correlation between various traits that contribute to yield increase and accumulation of biologically active compounds in leaves. Morphological characteristics (plant height, number of leaves per plant, number of shoots per plant, leaf length, leaf width and total leaf yield) and biochemical parameters (dry matter, nitrates, ascorbic acid, mono sugars, chlorophyll, carotene, flavanoids, hydroxycinnamic acids) were analyzed. Research on introduction and mobilization of genetic resources, preservation and sustention of genetic collection of representatives of Allium L. genus were carried out within the framework of the State Assignment. Dispersion analysis showed significant differences among the tested genotypes for all the studied parameters, namely phenotypic, biochemical and yield traits. The relation between the parameters was assessed using Pearson coefficient. A positive close connection was revealed between the plant height and leaf length (0.792), plant height and flavonoids (0.744), the number of shoots and the number of leaves (0.818), dry matter and nitrates (0.903), mono sugars and ascorbic acid (0.739), mono sugars and hydroxycinnamic acids (0.700), mono sugars and flavonoids (0.704), ascorbic acid and hydroxycinnamic acids (0.964), ascorbic acid and flavonoids (0.937), hydroxycinnamic acids and flavonoids (0.987). A negative close connection was noted between the height and number of shoots (-0.757), plant height and chlorophyll (-0.814), number of shoots and leaf length (-0.951), number of leaves and leaf length (-0.717), dry matter and mono sugars (-0.804 ), nitrates and mono sugars (-0.887). The revealed patterns are of interest for constructing a model of varieties and selection usage.

Performance of Two Rape (Brassica napus) Cultivars under Different Fertilizer Management Levels in the Smallholder Sector of Zimbabwe

Crop response to fertilizer application depends on the physiological and morphological characteristics of the cultivars, thus causing cultivar differences in growth rate and final yield. A study was carried out in the Zvimba smallholder farming area of Zimbabwe, from November 2016 to February 2017, to investigate the performance of two rape (Brassica napus) cultivars under different nitrogen fertilizer management levels. An experiment was set up in a randomized complete block design, replicated three times, with two rape varieties, Hobson and English Giant, and 5 ammonium nitrate (AN) (34.5% N) fertilizer application rates (200 kg/ha, 300 kg/ha, 350 kg/ha, and 400 kg/ha) as factors. Nitrogen fertilizer rates had a significant (p<0.05) effect on leaf length at 6 WAP and 7 WAP. Nitrogen fertilizer application levels had significant effects on both in-season and total fresh leaf yield. There were no varietal effects on the leaf length (p>0.05), in-season yield and total leaf yield (p>0.05), and there were also no variety ∗ fertilizer application level interaction effects on leaf length, in-season yield and total leaf yield (p>0.05). From the results of this study, English Giant rape would maintain a longer leaf length than Hobson up to the end of the season, but the two cultivars have similar yield response to fertilizers’ application rate. Both the English Giant rape and Hobson rape cultivars can, therefore, be recommended for production in the Mhondoro smallholder farming area of Zimbabwe and other areas with similar climatic and soil characteristics.

Roles of different fertilizer management practices on mulberry leaf yield and quality

Effects of fertilizer management practices on leaf yield and quality of mulberry plant are important for sustainable mulberry plant production. This study was undertaken to improve the growth, yield and biochemical contents in an instant available form in mulberry plant through different fertilizer management practices. There were four fertilizer management practices like control (CT), basal (BS), urea+magic growth (UM) and basal+urea+magic growth (BUM) were applied on mulberry plant (Morus SPP.). Results of this investigation revealed that among the various fertilizer treatments on the foliar application of (3 g urea + 3 mL magic growth) per liter water with BSRTI recommended BS of NPK performed well in respect of growth parameters and biochemical constituents. The highest 10 leaf area (638.64 cm2), leaf number per branch (50), total leaf weight per plant (785.64 g), node per meter (28.67), specific leaf weight (0.005817 g/cm2), length of longest shoot (173.25 cm) and total leaf yield per hectare per year (41 610 kg) were noticed in BUM treatment followed by UM, BS and CT treatments. Further the highest moisture (74.38%), moisture retention capacity (33.31%), total mineral (12.10%), total sugar (3.99%), reducing sugar (4.05%), crude protein (21.01%), starch (9.72%) and soluble carbohydrate (11.41%) were also recorded in BUM treatment as compare to UM, BS and CT treatments. The outcome of research implies that among the four fertilizer management practices foliar spray of (3 g urea + 3 mL magic growth) per liter water with BSRTI recommended BS dose of NPK performed well and successfully augments the productivity and biochemical constituents of mulberry plant.

Vegetative growth of Amaranthus hybridus and Amaranthus tricolor under different watering regimes in different seasons in southern Mozambique

Drought-tolerant crops with high nutritional value such as amaranth leafy vegetables have the potential to improve the diet of rural communities in dry semi-arid areas of southern Mozambique. A study was conducted aiming to assess the vegetative growth and leaf nutritional content of Amaranthus hybridus and A. tricolor when subjected to different watering regimes (80%, 50% and 20% of total available water) during the rainy and dry seasons, and ascertain the relationship between temperature and day length affecting the leaf yield of the two species. Six field trials were conducted in a randomised complete block design with 2 × 3 factorial layout with six replications in Maputo. Vegetative growth was sensitive to soil water at 50% and 20% of available water. However, the leaf and side-shoot number, leaf area and yield were less sensitive to short-interval water deficits during the rainy season. Leaf calcium and crude protein contents were higher at low water levels. Leaf yield was significantly affected by temperature and day length, where total leaf yield increased during the rainy season, and decreased during the dry season. Both species have the potential for sustainable leaf production during rainy and dry seasons.

Effect of nitrification inhibitors on physio-chemical properties, growth and yield attributes of Mulberry (Morusspp.)

Experiments were conducted to assess the effect of urea amended with nitrification inhibitors. Application of urea amended with nitrification inhibitors were influenced physiochemical properties of soil such as pH (7.47) and electrical conductivity (0.25 mmhos/cm) were significantly low with neem oil coating as well as in DCD. Similarly the chemical properties such as available phosphorus (64.88 kg/ha) and potassium (299.88 kg /ha) were also significantly higher and on par due to coating with neeem oil or DCD as nitrification inhibitor. Significantly high soil physical properties such as porosity 45.69 % as well as water holding capacity and low bulk density was found low (1.14 mmhos/cm) were also found in soil treated with both neeem oil and DCD amended urea. The biochemical and physiological attributes viz., chlorophyll, sugar, leaf protein, moisture content and moisture retention capacity of mulberry were found higher when neem oil or DCD used as nitrification inhibitor. The yield parameters such as number of shoot per plant (10), plant height (177 cm), length of longest shoot (180 cm), number of leaves/shoot (32.18) and total leaf yield (11353 kg/ha/crop) were observed at par with the use of DCD and neem oil as nitrification inhibitors.

Occurrence of Diseases on Muga Silkworm Host PlantPerseabombycinaKost. in District Bageshwar, Uttarakhand-A Survey Report

In sericulture, diseases of silkworm host plants are the major constraint in realising the foliage potentiality of the plant under feeding of silkworms and the ultimate conversion of cocoons during crops. Diseases make the leaf unpalatable for muga silkworms and cause reduction in total leaf yield and ultimately affect cocoon yield production. In the present article, a survey of foliage diseases was carried out on one of the primary host plant Persea bombycina Kost. of Muga silkworm during the calendar year 2012 and 2013. It was observed that foliar diseases like red rust, leaf spot, grey blight and brown blight are common diseases occurring on the plant species in District Bageshwar of Uttarakhand state, which affects the foliage yield of the plant as well as quality and quantity of cocoon production.

Leaf and Fruit Yield Performance of <i>Telfairia occidentalis</i> Hook F. (Fluted Pumpkin) as Influenced by Fruit Size

An experiment to ascertain the influence of fruit size on the yield of fluted pumpkin (Telfairia occidentalis Hook F.) was conducted in 2011 and 2012 at Nsukka. The mature fruits of T. occidentalis were graded into three length groups: large (more than 50 cm), medium (34-50 cm) and small (less than 34 cm). The experiment was laid out in randomized complete block design with six replications. The following data were collected: length of the longest vine, number of leaves/plant, vine diameter, marketable leaf and fruit yield. Data collected were subjected to analysis of variance while Genotype by Genotype x Environment interaction biplot was used to show which-won-where among the groups. Significant means were separated using Fisher’s least significant differences. Medium sized fruits gave the highest marketable leaf yield that was significantly higher than the small sized fruits in both years. Small sized fruits were significantly (p<0.05) lower in total leaf yield, fruit weight/hectare, fruit circumference (33.9 cm) and length (22 cm). The biplot explained 100% of the variation in the fruit sizes. Large sized fruits were the best performer in fruit length, while medium sized fruits performed better in total marketable leaf yield, average fruit weight, number of fruits/hectare and total fruit weight/hectare. The highest Benefit Cost Ratio of 1.2 and 2.6 in 2011 and 2012, respectively were obtained from medium sized fruits Medium sized fruit are recommended in favour of small sized fruit for leaf and fruit production, having higher economic returns.

EFFICACY OF BIO-FOLIAR SPRAY ON GROWTH AND BIOCHEMICAL PARAMETERS OF DIFFERENT MULBERRY VARIETIES

The study was undertaken to improve the growth and biochemical contents in an instant available form through foliar combination of spirulina, soybean and vermiwash. 15, 30 and 45 µg mL-1 concentrations of bio-foliar were sprayed on five different mulberry varieties namely S-1, S-146, S-1635, BR-2 and AR-14 to know their performance on growth parameters and biochemical constituents. Results of the investigation revealed that, among all experimental concentrations mulberry varieties and treatments, BR-2 and S-1635 varieties were performed well in respect of growth parameters and biochemical constituents. Highest leaf area (234.07 cm2) and total leaf yield per hectare (51.48 tons) was noticed in BR-2 mulberry variety at 45 µg mL-1 followed by S-1635 variety. Further highest protein (0.555 mg g-1), carbohydrate (0.668 mg g-1), carotenoids (0.550 mg g-1), total chlorophyll (2.04 mg g-1) and crude protein content (26.67%) were recorded at 45 µg mL-1 concentration by BR-2 variety followed with S-1635 variety as compare to control. The outcome of research implies that, among five mulberry varieties and concentrations, BR-2 and S-1635 varieties with 45 µg mL-1 concentration performed well and successfully augments the productivity and biochemical constituents of different mulberry varieties without any side effect.

Herbage yield in Signalgrass pastures as affected by grazing management

Signalgrass is largely planted as cultivated pasture in Brazil, but no management targets have been identified. The objective of this study was to evaluate daily herbage accumulation rate (HAR) in Signalgrass pastures grazed at two intensity x two frequency treatments using steers. Target intensities corresponded to 5 and 10 cm post-graze sward height and frequencies were determined by pre-graze sward light interception (LI = 95 or 100%) by the canopy. The trial was carried out from January 2007 to April 2008 on an Entisol. Less frequently grazed pastures had higher HAR during the entire period (29 and 36 kg/ha for 95 and 100%-LI, respectively). There was no intensity effect on HAR, except in the 2007 summer season (January to March) when pastures grazed to 10 cm had a higher HAR (59 kg/ha) than those grazed to 5 cm (45 kg/ha). Total leaf yield increased when regrowth was longer (7930vs. 8729 kg/ha for 95 and 100%-LI, respectively), but stem and dead material yield increased as well (4877 vs. 7155 kg/ha for 95 and 100%-LI, respectively). The advantages of extending the rest period due to increased HAR was counterbalanced by the great influence of stem and dead material, decreasing pasture leafiness and likely forage nutritive value on the grazed stratum.

COMPARATIVE PERFORMANCE OFLEUCAENA PALLIDAANDCALLIANDRA CALOTHYRSUSON AN ACID SOIL IN A SUB-HUMID ENVIRONMENT IN BURUNDI

SUMMARY The influence at the first cutting on the growth and yield of Leucaena pallida and Calliandra calothyrsus was studied on an acid soil with high Al saturation in the mid-altitude highlands of Burundi. During the first 15 mo after planting, average leaf and wood yield of L. pallida were 1.2 and 1.1 t ha-1, respectively, whereas those of C. calothyrsus were 5.0 and 4.5 t ha-1, respectively. In the second year, average leaf yield of L. pallida was 24% of that of C. calothyrsus. The age at which L. pallida was cut back for the first time—3, 6, 9, 12 or 15 mo after planting—did not influence total leaf yield during the first 15 mo nor that of the subsequent nine mo of growth. Total leaf yield of C. calothyrsus was highest when the trees were cut back nine mo after planting. Relative to Calliandra, L. pallida showed relatively low productivity on the Al-toxic highland soil, and therefore it is not recommended for fodder or wood production in this environment.

Regeneration of patchouli (Pogostemon cablin Benth.) plants from leaf and node callus, and evaluation after growth in the field

Pogostemon cablin (Benth.) is commercially important for its aromatic patchouli oil. Plants were regenerated through callus culture from leaf and nodal segments. Highest callusing was obtained from leaf explants in Murashige and Skoog (MS) medium supplemented with 3% sucrose, 0.8% bacto agar and 2 mg/L NAA + 0.5 mg/L BA. Shoot formation frequency was maximum (83%) with BA at 1.0 mg/L. Regenerated plantlets were rooted on MS medium with auxins. Maximum (90%) rooting was obtained using 0.5 mg/L NAA. Plantlets were grown for 4 weeks in this medium and then transferred to pots containing sterile sand in a moisture saturated glass chamber under laboratory conditions. The established plants were grown in pots filled with a mixture of sand∶soil∶manure (2∶1∶1) under natural daylight conditions in the field. The total leaf yield was increased in the tissue culture derived plants. These plants were dwarf and had higher specific leaf weight (leaf thickness) and leaf area compared to control plants.

The productivity of Tipuana tipu under three cutting regimes in southeast Queensland

The tree legume Tipuana tipu, which has potential as a browse species in sub-tropical regions, was subjected to three cutting frequency regimes of 6, 8 and 12 week intervals at a cutting height of 1 m. Cutting at 12 week intervals gave a total leaf yield of 4.02 t/ha/year which was significantly higher than the other two treatments. There was 100% survival of all plants in all treatments over 2 years and the implications of the results for the management of Tipuana tipu in a hedgerow system for folder production are discussed.

Independence of dry matter yield and leaf yield among perennial ryegrass varieties differing in seasonal yield distribution

AbstractFour varieties of perennial ryegrass (Lolium perenne L.), (Ba11316, Merlinda, Morgana and Talbot), with similar ear emergence dates but differing in seasonal yield distribution were compared over two harvest years (1992 and 1993) in a small plot trial employing six levels of fertilizer N (100 to 600kg Nha−1 year−1 applied monthly as split dressings). In each year, a conservation cut in May was followed by five further harvests at monthly intervals. Herbage samples from each of the twelve harvests were separated into leaf lamina and other tissues, and the yield of leaf lamina calculated. The percentage of flowering tillers was determined in May and July of each year, Ba11316 produced significantly more dry matter (DM) than the other three varieties at six of the twelve harvests, but its total DM yield over all twelve harvests was 5% less than Merlinda and 3% less than Morgana, owing to lower yields of reproductive growth in May of both years. Varieties also varied in mean leaf content of the herbage over all harvests, Ba11316 being 69 g kg−1 higher than that of Merlinda. Differences among the varieties in leaf content were primarily because of difference in proportion of flowering tillers, Ba 11316 having a lower proportion of flowering tillers than the other three varieties. However, the mean leaf content of the tetraploid Merlinda was significantly lower than that of Morgana although these two varieties had a similar mean percentage of flowering tillers. Despite its lower total DM yield, Bal 1316 produced 16% and 14% more leaf over the two harvest years than Merlinda and Morgana respectively. Total leaf yield of Talbot was significantly higher than that of Merlinda and Morgana, although Talbot had been developed twelve years earlier than the other two varieties.

Management practices for tropical grasses and their effects on pasture and milk production

Two experiments examined the effect different pasture management strategies had on individual cow milk yield during the summer wet season. In control treatments pasture was continuously grazed. In managed pastures the aim was to produce swards with a high leaf and low stem content. The grasses Panicum maximum cv. Gatton and Brachiaria decumbens were used in both experiments. Experiment one consisted of three pasture treatments; the stock were 1 8 Friesian cows. The control treatment was grazed continuously with no pasture management and was compared with two subjectively applied management treatments in which pasture was either slashed or stocked at variable rates in an attempt to increase pasture quality. The experiment lasted 17 weeks. Each time pastures were slashed or extra cows were added milk yield per cow fell. The lower each grass was slashed or the greater the number of cows added to a paddock the greater the fall in milk yield. Measurements of pasture yield, height and structural composition showed that slashing and variable stocking could increase the leaf percentage in the pasture, but not without seriously decreasing total leaf yield. In experiment two, 24 Friesian cows were used to compare the following treatments over a 10-week period (a) control-continuous grazing, (b) rotational grazing using a 2-week grazing, 2-week spelling regime and (c) rotational grazing with slashing after each grazing period. Milk yields averaged 10.6, 9.8 and 9.6 kg/cow day1, respectively (P> 0.05), and 10.1 and 9.9 kg/cow day-1 for B. decumbens and P. maximum pastures (P> 0.05). As in the first experiment, leaf percentage was increased by management treatments, but not without decreasing total pasture yield to the level where it limited milk production. Leaf yields could only be increased with an associated increase in total pasture yield. It was concluded that grazing management decisions should be based on total pasture on offer rather than any percentage component of total yield.
