Abstract. Drought stress affects the growth and yield of soybean. Stunted growth will have an impact on
yield. This study aims to determine the effect of drought stress on the growth characteristics and grain
yield of soybean. This research uses a randomized complete block design (RCBD) and three replications.
The first factor was soil moisture content consisting of three levels, i.e., 100%, 75%, 50%, and 25% field
capacity. The second factor was the growth stage consisting of three kinds, i.e., the vegetative active,
flowering, and seed filling stages. The results showed that soil moisture content below 75% field capacity
reduced the leaf area index (LAI), leaf area duration (LAD), specific leaf area (SLA), net assimilation rate
(NAR), crop growth rate (CGR), the seed weight per 100 seeds, and the weight of the seeds per plant. In
seed filling stage is more sensitive to water shortages than the vegetative or flowering stages. At all stages
of growth, a higher drought level equals a higher decrease in the soybean growth and yield. For future
research, we suggest that soybean planting utilize 100% field capacity

No full textNutrients are one of the most important elements for plants. Lack of nutrients causes growth and yields will not be optimal. The use of organic liquid human urine and NPK fertilizer is a source of micro and macronutrients to increase the yield of black cute rice.This study aims to determine the best combination dose of organic liquid human urine and NPK fertilizer to maximize the yield of black cute rice. The research was arranged in a randomized complete block design (RCBD) with two factors and three replications. The first factor was human urine liquid organic fertilizer, which consisted of three levels, namely 0, 500, and 1000 L ha-1. The second factor was the dose of NPK compound fertilizer, which consisted of three levels, namely 0, 150, and 300 kg ha-1. The difference between the averages of the treatment was compared using Duncan′s new multiple range test (DMRT) at a 5% significance level. The results showed that a combination of organic liquid human urine and NPK fertilizer could increase the number of productive tillers, canopy dry weight, and grain dry weight of black cute rice. The highest grain dry weight was found at the combination between human urine of 1000 L ha-1 and NPK compound of 300 kg ha-1 and yieldedthe maximum grain dry weight of 8.633 tons ha-1 in Litosolsoil. The combination between human urine of 1,000 L ha-1 and NPK compound of 300 kg ha-1 can maximize the yield of black cute rice. For future research, we recommend that the combination between human urine of 1,000 L ha-1 and NPK compound of 300 kg ha-1 can use in other rice varieties
Nutrient uptake and yield of rice (oryza sativa) applied with mycorrhizal fungi using different doses of nitrogen and phosporus fertilizers
No full textRainfed rice fields in general often lack water and nutrients that are difficult for their roots to reach. The Vesicular Arbuscular Mycorrhiza (VAM) fungus can assist in absorbing water and nutrients to increase the efficiency of nitrogen and phosphorus fertilizers. The purpose of this study was to determine the uptake of N, P, and K nutrients and the yield of rainfed lowland rice applied with VAM at different doses of N and P. This research used a completely randomized block design with two factors and three replications. The first factor was nitrogen with a dose of 0, 45, 90, and 135 kg/ha,
while the second factor was phosphorus at 0, 25, 50, and 75 kg/ha. The authors conducted this study in rainfed rice fields in Demangan, Sambi, Boyolali, Central Java, Indonesia, from March 30, 2019, to July 14, 2019, at an altitude of 113 m above sea level. The results showed that VAM could increase the uptake of nitrogen, phosphorus, and potassium and increase yield using N and P fertilizers at 90 kg/ha and 75 kg/ha, respectively. This research shows that the use of N and P fertilizers at 90 kg/ha and 75 kg/ha, respectively, is sufficient to cultivate rainfed rice applied with mycorrhizal fungi

The Vesicular Arbuscular Mycorrhiza (VAM) fungus can assist in absorbing water and nutrients to
increase the efficiency of nitrogen and phosphorus fertilizers. The purpose of this study was to
determine the uptake of N, P, and K nutrients and the yield of rainfed lowland rice applied with VAM
at different doses of N and P. This study was conducted in rainfed rice fields in Demangan, Central
Java, Indonesia, during 2019. This research was laid out in completely randomized block design with
two factors and three replications. The first factor was nitrogen with a dose of 0, 45, 90, and 135 kg/ha,
while the second factor was phosphorus at 0, 25, 50, and 75 kg/ha. The results showed that VAM could
increase the uptake of nitrogen, phosphorus, and potassium and increase yield using N and P fertilizers
at 90 kg/ha and 75 kg/ha, respectively. This research shows that the use of N and P fertilizers at 90
kg/ha and 75 kg/ha, respectively, is sufficient to cultivate rainfed rice applied with mycorrhizal fungi.
Based on the discussion, it can be concluded that the application of mycorrhizae is beneficial in rainfed
rice cultivation because it can suppress the use of N and P fertilizers by increasing the uptake of N, P
and K nutrients and increasing yields. In addition, in rice cultivation in rainfed rice fields, it is better to
use mycorrhizae
Soybean Varieties Respond to the Shade of Teak Trees
No full textLight is one of the environmental factors that greatly affect the growth and yield
of crops in general, including soybean plants. The purpose of this study was to determine the
effect of shade on yield and yield components of soybean varieties
Methods: The research method was a randomized complete block design (RCBD) with three
replications. The first factor was the kind of variety which consisted of two levels, i.e., Dena I
and Anjasmara. The second factor was the level of shading, which consisted of four levels, i.e.,
0, 10-20, 20-30, and 30-40%.
Result:The results showed that shade decreased the number of filled pods, dry pod weight per
plant, 100 seeds weight, and seed yield ha -1 . As the shade increases, the lower the yield and
component of soybean yields increases.The decrease in seed yield ha -1 of Dena I variety at 10-20,
20-30, and 30-40% shade was 22, 14, and 50%, respectively, while the Anjasmara variety was 9,
49, and 59%. Shade decreases yields and yield components of Dena I and Anjasmara varieties. In
the higher level of shade, the yield reduction will increase
