Effect of Kieserite on Physiological Characteristics of Soybean Varieties under Dryland Conditions

Soybean is a legume that can be cultivated in various types of agroecosystems such as lowlands, dry land, and swamps with various types of soil. This research aims to analyze the effect of mycorrhizal application on the growth and yield of soybeans planted in various agroecosystems. The research was designed with a two-factor randomized block design. Location of soybean planting as the first factor consists of four soybean development locations in Takalar Regency, South Sulawesi, namely: soybean cultivation in dry land, lowland in Galesong subdistrict, soybean cultivation in dryland, and lowland in South Galesong subdistrict. Application of mycorrhizal is the second factor which consists of two levels: no application, and mycorrhizae application. The results showed that the location of planting had a significant effect on soybean production, where soybean cultivation in lowlands resulted in significantly higher soybean production. The mycorrhizal application treatment obtained significantly higher soybean growth and production. The results of the analysis of soil chemical properties show that the total N content of soil in lowland land is moderate, P-available has low status, and low C-organic status. Galesong dry land showed a high total N content of 0.59%, but available P and organic C are very low.

Domestic soybean production is getting weaker due to drought stress which affects all aspects of plant growth and metabolism, besides using adaptive plant varieties, increasing plant nutrition, especially potassium, also affects increasing plant tolerance to drought. The research aimed to examine the effect of potassium application on the morphophysiological of two varieties of soybean under drought stress. The research was conducted in a plastic house, Deli Serdang Regency, North Sumatra, using a randomized block design with three factors. The first factor was soil water content condition, which consisted of 80% and 40% field capacity. The second factor was variety, consisted of Grobogan and Dering-1. The third factor was the application of potassium, consisted of without potassium 100, 200, 300 kg KCL ha−1. Result showed that drought stress decreased potassium uptake, the relative water content (RWC) of leaf and plant height. Grobogan variety more adaptive to drought stress with the highest plant height (71.49 cm), K content (1.77%), K uptake (43.85 mg/plant), and leaf RWC (37.91%). Application of K at a dose of 200 kg ha−1was the most appropriate to encourage the growth of soybean plants under drought stress with the highest total K (1.76%) and leaf RWC (44.40 mg/plant).

Edamame soybeans have excellent prospects for development in the lowlands. In order to grow well, edamame soybeans need liquid organic fertilizer as a nutrient supply and proper spacing. The objective of the research was to evaluate the effect of spacing treatment and application of liquid organic fertilizer (LOF) on soybean edamame growth and production. A field research was conducted in Medan from September until December 2019, using a factorial randomized block design with two factors and three replications. The first factor is spacing treatment of edamame, namely 40cmx20cm; 30cm x 20 cm and 20cm x 20cm. The second factor is LOF application consisting of 40; 60 and 80 mL/L of water. Research result showed that spacing of 30cm x 20cm treatment increased the number of productive branches. LOF treatment of 40mL/L of water increased the dry weight of 100 seeds. The interaction between plant spacing and LOF application had no significant effect on all observed variables.
