Abstract

Drought conditions are a problem that is often found in soybean cultivation because in general soybeans are planted in the dry season where production is largely determined by the amount of water given. This study aims to evaluate the physiological and production characteristics of several soybean varieties under drought-stress conditions. 10 soybean varieties were tested at three levels of watering. This study was designed using a Completely Randomized Design with Factorial. The research was carried out in the experimental garden of the Faculty of Agriculture at Universitas Pembangunan Nasional Veteran Jawa Timur. The results showed that increasing the concentration of PEG given in the germination phase decreased germination, primary root length, and number of seminal roots. A significant interaction between varieties and water application occurs in the variable pod weight per plant. The genetic diversity of each variety tested showed differences in all of the observed variables. The decreasing availability of water affects all metabolism in plants, giving 50% of the normal requirement of water shows the lowest results in all observed variables. While giving 75% water is generally not significantly different from giving 100% water for normal needs

Abstract

Purslane is an annual plant that has various benefits. This plant contains omega 3 which is equivalent to other types of vegetables. So far, purslane is still considered a weed, so it doesn't have a cultivation technique to get the results. This study aims to obtain a combination of planting media for the growth of purslane. This research is the beginning to increase the purslane omega 3 content. Because genetic factors and environmental conditions can affect the growth and development as well as the chemical content of plants. The experimental design used a completely randomized design (CRD). The planting media used were: soil, soil + husk charcoal, soil + compost, and soil + husk charcoal + compost. The treatment was repeated 4 times, so there are 12 observation units. Observations were made on the number of leaves and the number of branches. The results showed that the combination of soil+compost gave the best effect on the number of leaves and the number of branches of the purslane seedling

Abstract

Soybean productivity in Indonesia remains relatively low, partly due to declining soil fertility. One approach to address this issue is the application of liquid organic fertilizer (LOF) and phosphate fertilizers, such as SP-36. This study aimed to evaluate the effects of various concentrations of banana corm-based LOF and different doses of SP-36 fertilizer, as well as their interaction, on the growth and yield of soybean plants (Glycine max L.). The research was conducted in Medokan, Surabaya, using a two-factorial Randomized Block Design (RBD) with four levels of LOF concentration (0, 500, 600, and 700 ml/l) and three levels of SP-36 concentration (150, 200, and 250 kg/ha). The observed parameters included plant height, number of pods, percentage of empty pods, seed weight per plant, seed weight per hectare, and fruit set. The results indicated a significant interaction between LOF and SP-36 on plant height 42 days after planting, number of pods, percentage of empty pods, and fruit set. The most effective treatment was the combination of 600 ml/l banana corm LOF and 200 kg/ha SP-36. However, seed weight per plant and hectare did not show a significant effect. This study concludes that the appropriate combination of banana corm LOF and SP-36 fertilizer can significantly enhance soybean growth and yield. It is recommended to use 600 ml/L of banana corm LOF combined with 200 kg/ha of SP-36 fertilizer to optimize plant height, number of pods, and fruit set in soybean cultivation.
