Abstract

The objectives of this study were: (1) to determine the effect of manure and phosphate fertilizers on the growth and yield of hybrid maize; (2) to identify the type of manure and dosage of phosphate fertilizer that produced the best growth and yield; and (3) to analyze the correlation between growth components and yield. The research was conducted using an experimental method with a randomized block design consisting of 12 combinations of manure and phosphate fertilizer treatments, each replicated three times, resulting in 36 experimental plots. The results showed that: (1) application of manure and phosphate fertilizers significantly affected plant height, leaf number, leaf area index, stem diameter, root volume, ear length, ear diameter, ear weight without husks per plant and per plot, number of seeds per ear, 100-seed weight, and dry seed weight per plant and per plot, but had no significant effect on relative growth rate and number of cobs per plot; (2) the treatment of 10 t/ha of chicken manure combined with 150 kg/ha of phosphate fertilizer produced the highest dry seed yield of 6.05 kg per plot (equivalent to 10.08 t/ha), which was not significantly different from treatments with sheep manure or cow manure at 10 t/ha combined with 150 kg/ha phosphate fertilizer, or with chicken, sheep, or cow manure at 10 t/ha combined with 100 kg/ha phosphate fertilizer; and (3) there was a significant positive correlation between plant height, leaf number, leaf area index, stem diameter and dry seed weight per plot, while root volume and relative growth rate showed an insignificant positive correlation with yield.

Abstract

This experiment aims to determine the effect of the combination of phosphate fertilizer and plant spacing on the growth and yield of soybean (Glycine smax L.) Anjasmoro variety. The experiment was carried out in Mekarjaya Village, Gantar District, Indramayu Regency - West Java. The time of the research was carried out from August to October 2021. The location is located at an altitude of ± 50 meters above sea level (masl), the soil type is the association of Latosol and Regosol, including type D (moderate) rain. The experimental method used is the experimental method with a factorial randomized block design (RAK), treatment consists of 2 factors repeated three times. The first factor is the spacing which consists of three levels, namely 40 cm x 25 cm, 40 cm x 30 cm, and 40 cm x 40 cm. While the second factor is the dose of phosphate fertilizer which consists of three levels, namely 100 kg/ha, 150 kg/ha, and 200 kg/ha. The main observation data were processed using linear model statistical tests, analysis of variance, and Scott-Knot cluster further test analysis. To determine the correlation between the treatment with the components of growth and yield of soybeans, the correlation used is the Product Moment correlation coefficient. The experimental results showed: (1) The combination of phosphate fertilizer and plant spacing affected the number of leaves at 14 DAP, the number of branches at 28 and 35 DAP, leaf area index at 14, 28, and 35 DAP (2) Dry seed weight per plot The highest yield was produced by the combination of treatment F, with a spacing of 40 cm x 30 cm and a phosphate dose of 200 kg/ha with a dry harvest weight of 0.711 kg per plot (equivalent to 1.8 tons/ha), and (3) There was a significant correlation between height plants aged 28 DAP and 35 DAP and the number of leaves at 28 DAP with dry seed weight per plot.

Abstract

This study aimed to determine the interaction effects of gibberellin concentrations and compost application on the growth and yield of the mung bean (Vigna radiata L.) variety Vima 4. The experiment was conducted from August to October 2021 at the Agricultural Complex of the Ma'had Al-Zaytun Campus, Mekarjaya Village, Gantar District, Indramayu Regency, West Java Province. The site is situated approximately 50 m above sea level, on Latosol–Regosol soils, under a Type D rainfall pattern. The research employed a factorial randomized block design (RBD) with three replications. The first factor was gibberellin concentration (5 ppm/plant, 10 ppm/plant, and 15 ppm/plant), while the second factor was compost dosage (10 tons/ha, 15 tons/ha, and 20 tons/ha). Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s multiple range test, and correlation analysis was conducted using the product-moment correlation coefficient. Results showed that there was a significant interaction between gibberellin concentration and compost application on plant height and leaf area index (LAI). The treatment combination of 10 ppm gibberellin with 15 tons/ha compost yielded 0.67 kg of seeds per plot, which was not significantly different from other treatments. A significant positive correlation was observed between plant height and number of leaves at 35 days after planting (DAP) and between plant growth at 21 DAP with seed yield per plot. The correlation between plant growth traits and yield was categorized as moderate.
