Zea mays Saccharata (Sweet corn) is a horticultural commodity that is have high carbohydrates and contains free sugars and starch (Wahditiya, 2016). sweet corn imports increased 42.46% from 517.5 thousand tons in the previous year to 737.2 thousand tons (BPS, 2021 in Amelia and Sugiharto, 2022). This high demand is not matched by availability. Efforts to meet this demand include improving cultivation techniques such as used of superior varieties and ecological management. The combination of organic and anorganic fertilizers can play an important role because it can maintain soil health, productivity and plant fertility. The combination of goat fertilizer and KNO3 is expected to increase vegetative and generative performance. The research method used RAKF. The first factor is the dose of goat manure, K1 = 5 tons/ha, K2 = 10 tons/ha, K3 = 15 tons/ha. The second factor is the application of white KNO3 fertilizer P1 = 50 kg/ha, P2 = 100 kg/ha, P3 = 150 kg/ha. There were 9 treatment combinations and repeated 3 times and 5 samples. The observed parameters include: Plant height, number of leaves, leaf area, and flowering age. Data obtained from the observations of each variable were subjected to the F test with the method of variance (ANOVA). If the treatment combination accepted H1 then the comparison test will be done BNT 5%. The results showed that there was no interaction between the application of goat manure and KNO3 on the growth and yield. The application of KNO3 has a significant effect on the vegetative period of the plant number of leaves, plant height, stem diameter, and early flowering age of the plant.

The Impact of 9 Years of Swine Wastewater Application on the Mineral and Organic Quality of Soil in Various Agricultural Crops

This study evaluates the long-term effects of swine wastewater (SWW) on relevant parameters for soil fertility, including calcium (Ca), magnesium (Mg), potassium (K) cations, cation exchange capacity (CEC), and organic matter (OM) in an agricultural area with 9 years of crop cultivation. Three types of SWW (raw, after leaving the biodigester, and after the manure plant) were analyzed with four application rates of SWW (0, 100, 200, and 300 m3.ha−1), associated or not with mineral fertilization, resulting in eight treatments. The study found that the long-term use of SWW had significant effects on soil parameters. Principal component analysis (PCA) was used to summarize the data. The soil’s calcium (Ca), magnesium (Mg), and cation exchange capacity (CEC) levels were higher in soybean compared to other crops and natural soil. Similarly, the treatment with 0 m3.ha−1 of pig manure and without mineral fertilization showed higher levels of these nutrients. In contrast, potassium (K) was found in greater quantities in oats, SWW from the biodigester, higher doses of manure, and with mineral fertilization. The crops had a higher organic matter (OM) content compared to the natural soil, with corn and raw SWW showing the most significant increase.

Using several types and doses of manure to increase the productivity of Konjac plants (Amorphophallus muelleri Blume)

Amorphophallus muelleri (known as "porang" in Indonesia) can be used as a high-value alternative food source and potentially be a glucomannan production source. Due to its limited production, Indonesia has yet to meet the Amorphophallus muelleri (konjac) flour demand. During growth, konjac plants require sufficient fertilization to increase production and yield large tubers. This study aims to determine the appropriate types and doses of manure fertilizers to enhance konjac plant productivity. The research employed a randomized complete block design with ten treatments using sheep, chicken, and cow manure, as well as a control, with doses of 1.5, 1, and 0.5 kg per plant, repeated four times. The results showed that using manure fertilizers significantly affected the growth of konjac plants, including plant height, stem diameter, leaf width, canopy diameter, and yield. The best dry weight results were obtained using chicken manure at 1 kg per plant (61.33 g) and 1.5 kg per plant (47.64 g). Using sheep, cow, and chicken manure increased konjac tuber yield by 94.95%, 93.55%, and 66.96%, respectively.

ENHANCING SPINACH (SPINACIA OLERACEA L.) SEED GERMINATION, LEAF BIOMASS PRODUCTION UNDER SALINE WATER STRESS: THE IMPLICATIONS OF ZINC AND COW MANURE

Plant growth and productivity is restricted due to significant influence of salt stress on the essential physiological processes. Zinc supplementation holds promise as a technique to improve the resilience under salt stress. An open field experiment was conducted to assess the leaf growth parameters of spinach (Spinacia oleracea) including seed germination, plant area, leaf area, length, width, leaf fresh weight as well as dry weight, and Number of leaves per plant. Spinach plants were irrigated with a defined electrical conductivity (EC) level of 4.16 dSm-1 in clay loam, non-saline soil. Cow manure, a form of organic waste rich in macronutrients and micronutrients was also investigated. This study focuses on examining the response of zinc and cow manure on spinach growth under salinity stress. Salinity stress resulted in reduction in seed germination, leaf area, width, length, leaf fresh and dry weight, with no significant effect on the number of leaves. High doses of zinc and cow manure (0.20g Zinc+ 150g Cow Manure + Salinity) meaningfully enhanced performance by increasing seed germination by 15-20%, leaf area 130 cm2, length 8.41 cm, width 4.8 cm , leaf fresh 0.67g and leaf dry weight 0.51g but didn’t affect the number of leaves. Overall, our results demonstrate that the application of zinc and cow manure induced resistance to salinity stress and impacts positively on Spinach growth. Future research can focus on how zinc affects enzymatic activities and various mechanisms under salt stress.

The influence of poultry manure on the yield and crop structure of spring rapeseed

The research was carried out to identify the optimal dose of bedding bulk poultry manure on the influence of the crop structure and the yield of spring rape seeds of Lunedi variety. The work was carried out in 2022-2023 in the forest-steppe zone of the Nizhny Novgorod region. Poultry manure loose (GOST 31461-2012) was applied in doses of 4, 6 and 8 t/ha (control - without fertilizers). The experiment was conducted on light gray forest loamy soil with low humus content, neutral reaction and mobile forms of phosphorus and potassium. Statistically proven changes in the structure of rape yield were noticed on the manured variants: the increase in length of the fruit (pod) was 0.40–0.67 cm, in pod weight – 0.04–0.12 g, the number of pods per plant increased by 1.4–2.1 times, the number of seeds in a pod increased by 2.5–4.6 seeds, seed productivity of a single plant increased by 1.9–3.0 times, the weight of 1000 seeds exceeded by 0.66–0.94 g. The application of poultry manure on all variants revealed a reliable increase in the yield of above-ground phytomass and seeds, the increase in rape biomass was 6.03–8.70 t/ha (LSD05 = 1.30), seeds – 0.94–1.26 t/ha (LSD05 = 0.46). The maximum increase in the biomass of rapeseed and seeds (6.03 and 0.94 t/ha) was established in the variant with a manure dose of 4 t/ha, since with an increase in the manure dose (6 and 8 t/ha) in excess of the minimum increase by 1.42–2.67 t/ha of plant biomass and 0.22–0.32 t/ha of seeds. The obtained results suggest that the optimum dose of poultry manure application to spring rapeseed on light grey forest soil (Alfisol) is 4 t/ha.

Shallot cultivation in tropical climate ecosystems using floating and non-floating systems with different doses of cow manure

Deep swamp is swampland with the longest flooding period, making it challenging for crop cultivation. However, by adopting a floating system, this prolonged duration of flooding can be used for shallot growing. Thus, this study aimed to ascertain the growth and yield of shallots cultivated in polybags using conventional non-floating and floating systems with the application of different doses of cow manure. The research was located in the experimental field and reservoir of the Faculty of Agriculture, Sriwijaya University (3°13’30.3′′ S; 104°38’55.1” E). Non-floating and floating farming systems were utilized with the application of 0, 10, 15 and 20 ton/ha of cow manure. The findings demonstrated that shallots cultivated in the floating system had lower numbers and length of leaf but could produce more bulbs in comparison to the conventional method. The application of 15 ton/ha manure in the floating system resulted in higher weights of fresh and air-dried bulbs per plant, weighing 74.40 g and 64.82 g, respectively, compared to those in the non-floating system (46.77 g and 37.84 g, respectively). In conclusion, the Bima Brebes shallot variety potentially can be cultivated in a floating system with the application of 15 tons of cow manure per hectare.

Esterco bovino e substâncias húmicas estimulam a morfofisiologia e a nutrição em pimentão

ABSTRACT Species of the genus Capsicum, especially peppers, are economically important and widely consumed worldwide. The application of animal waste as organic fertilizer is a simple and cost-effective technique for applying nutrients to the soil. Combining cattle manure with humic substances can stimulate plant metabolism, resulting in increased nutrient absorption and assimilation. Therefore, the objective in this study was to evaluate doses of cattle manure combined with humic substances for stimulating plant metabolism and morphophysiological and nutritional processes in pepper plants. A randomized block design with four replicates was used, in a 4×3 factorial arrangement consisting of four cattle manure doses (8, 18, 28, and 38 Mg ha-1) and three humic substance doses (0, 8, and 12 kg ha-1). Humic substances (12 kg ha-1) enhanced gas exchange, increasing net photosynthesis (34.2%), stomatal conductance (12.7%), instantaneous water use efficiency (15.87%), instantaneous carboxylation efficiency (37.37%), and absorbed energy conversion efficiency (23.53%). Cattle manure adequately met the crop’s nutritional requirements, while humic substances increased the number and thickness of plant root hairs. The most effective combination to increase photosynthetic activity in pepper plants was 38 Mg ha-1 of cattle manure combined with 8 kg ha-1 of humic substances. Humic substances stimulated positive morphophysiological responses in organic pepper crops, which resulted in increased production.

EFFECT OF CHEMICAL INDICATORS AND RESPIRATORY ACTIVITY ON THE RESIDENCE TIME OF VERMICOMPOSTS

Vermicompost is considered an environmental quality to manage agricultural residues because it improves the structure, provides nutrients to the soil, and helps to mitigate the impact on the environment. The objective of this study was to know the residence time by applying a kinetic model of carbon mineralization, evaluating chemical and biological parameters obtained during the processing time of a vermicompost. Earthworms (Eisenia fetida) were used comparing different doses of residual sludge (LR) at 0, 10, 20 and 40 Mg, keeping constant the dose of domestic waste (RD) and cattle manure (EV) at a ratio of 1:1 (dry basis). An AxB factorial design was used, where A represented the LR dose and B the type of residues (RD and EV); thus, eight treatments with nine replicates were compared. The pH, organic matter (MO), total nitrogen, C/N ratio, respiratory activity, C mineralization, and residence time were determined. The results of the treatments indicate a slightly alkaline trend. MO was different among treatments, with higher percentage of MO in EV and LR with 40 Mg of LR (28.92 ± 10.78 %, F (7,88) = 2.63, p ≤ 0.01). The percentage of total N was low, but the treatment containing 40 Mg of LR and RD (1.04 ± 0.62 %, F7,88 = 3.87, p < 0.01) stood out. C/N ratios < 20, indicating stability, were recorded in the treatments with LR and EV. The vermicompost obtained by 40 Mg of LR and EV complied with a minimum residence time (less than 70 days) during its processing, which makes it a highly recommendable option for application in agriculture.

Pengaruh Pupuk Kotoran Sapi dan Plant Growth Promoting Rhizobacteria pada Produksi Tanaman Buncis

The productivity of common beans has fluctuated in the last 5 years. The decrease and increase in productivity occur due to decreased soil quality due to a lack of organic matter. Plant productivity with excessive use of inorganic fertilizers can reduce soil fertility. The solution to restoring microbial activity and soil fertility levels can be taken through a nature farming approach, namely by utilizing organic fertilizers derived from cow manure and additional plant growth-promoting rhizobacteria (PGPR) biological fertilizers. This research was conducted at a production site on Jalan Tidar, Jember, East Java, from January to March 2023. The design used was factorial RAK with 3 repetitions. The first factor was the dose of cow manure, which consists of 4 levels, namely 0, 10, 15, and 20 tons/ha. The second factor was the concentration of PGPR, which consists of 4 levels: 0, 10, 15, and 20 mL/L. The results do not show any interaction between cow manure and PGPR on all parameters. Cow manure has a noticeable effect on growth parameters and quantity. The best dose of cow manure and the highest protein content value was 20 tons/ha. The concentration of PGPR had only a noticeable effect on plant height and number of leaves. PGPR concentrations of 15 mL/L and 20 mL/L both give the best results and produce the highest antioxidant activity value at 15 mL/L. Keywords: Antioxidant activity, common bean, cow manure, pgpr, protein

Release, availability and geochemical interaction of Fe in soil after long‐term integrated nutrient management in wheat

AbstractWheat contributes to about one‐fifth of the total calories and protein consumption by humans but is found lower in total iron (Fe) concentration than the targeted nutritional requirement, leading to increasing cases of anaemia and malnutrition in humans, especially in the developing countries. Therefore, it is the need of the hour to understand the dynamics of Fe in soil and its supply in relation to wheat productivity and grain quality. The objectives of this study were to examine the impact of long‐term (54 years) annual and biannual application of different doses of farmyard manure (FYM) (0, 5, 10 and 15 Mg ha−1) and nitrogen (0, 60 and 120 kg ha−1) under integrated nutrient management on the dynamics of Fe in soil along with its relationship with total Fe uptake in wheat. Additionally, the release pattern of native soil Fe and risk of Fe toxicity were evaluated. The highest grain yield of wheat (6.08 Mg ha−1) was observed under biannual application of FYM and nitrogen at 10 Mg ha−1 and 120 kg ha−1, respectively, which was approximately 155% higher than the control plot (F0N0). Under the dual season application of 15 Mg ha−1 FYM and 120 kg ha−1 nitrogen, the total Fe content (48.48 mg kg−1) and its uptake (270.52 g ha−1) in wheat grains were found at maximum. The soil incubation study revealed that the rate of release of Fe increased up to 30 days of incubation followed by constant rates indicating the establishment of dynamic equilibrium among the different Fe fractions. Thus, the present study was conducted for the first time to improve the understanding of changes in Fe concentration and rate of release in soil, which directly influence the Fe uptake in wheat grain under the long‐term integrated nutrient management practices.

Promoting smart agroforestry of sengon-based arrowroot and cardamom to support food security

The forest land has great potential to provide food and also contributes to achieving Indonesia’s forest and other land uses (FOLU) Net Sink 2030, as a concrete contribution of the forestry sector to addressing national and global needs, which can be done by promoting smart agroforestry. This research aims to provide smart agroforestry model of sengon (Falcataria moluccana) with arrowroot and cardamom, to analyze the sengon growth, the arrowroot and cardamom biomass productivities under the agroforestry models. The split-plot design was employed with six cropping pattern as the main plot, in three agroforestry models (sengon-arrowroot; sengon-cardamom; sengon-arrowroot-cardamom) and three monoculture plots, and three levels of the dosage of manure as subplots (0; 250; 500 g). The results showed that higher growth of sengon was found in the three agroforestry models (3.0-3.5 m3.ha−1) compared to monoculture (2.1 m3.ha−1). The highest dry weight of leaf, stem, root, tuber, fruit bunch and total biomass of arrowroot and cardamom was produced in the monoculture. These agroforestry models have the potential to support food security and Indonesia’s FOLU Net Sink 2030, which will be prospective mainstreaming in implementing Social Forestry programs.

Enhancing Leaf Flavonoid Production in Indian Camphorweed (Pluchea indica Less.) through the Provision of Chicken Manure

Indian camphorweed (Pluchea indica Less.) leaves exhibit antioxidant, antibacterial, anti-inflammatory, and antimicrobial activities, indicating significant potential for the pharmaceutical industry. This research aimed to determine the optimal rates of chicken manure for enhancing leaf and total flavonoid production in Pluchea indica. The study took place at the IPB Experimental Station in Bogor, Indonesia,spanning from July to October 2023. A completely randomized block design with a single factor (chicken manure doses) was employed: 0, 2.5, 5, or 7.5 kg per plant. Each treatment comprised three replications, each consisting of 20 plants. The results revealed that the application of chicken manure at 2.5 kg per plant led to significantly taller plants, more leaves, and tertiary branches compared to the control group. Specifically, the 2.5 kg dosage significantly increased the nitrogen content of the 7th leaf and the potassium content of the 3rd leaf. Meanwhile, the application of 5 kg of chicken manure per plant significantly boosted phosphorus content in the 3rd and 7th leaves and potassium content in the 5th and 7th leaves. However, no significant differences were observed in total flavonoid and antioxidant activity across all leaf positions with chicken manure application. Plants receiving 5 kg of manure demonstrated the highest fresh leaf weight (81.64 g) and dry weight (38.27 g), which were significantly greater than those receiving 2.5 kg per plant or no manure. Despite these variations, flavonoid production per plant did not show a significant difference with manure application.
