Analysis of Productivity of Soybean [Glycine max (L.) Merr.] for Production for Farmers in Indonesia
Productivity is an average measure of the production efficiency. This study was aimed at identifying the soybean productivity in Indonesia, including production and land area. Total Factor Productivity (TFP) was conducted on 100 farmers in Grobogan Regency, Central Java, which is determined by stratified random sampling. The result shows that the productivity value of soybean is 76.8%. This number can potentially increase output as big as 23.3% using the same input factors. The productivity of soybean in 2014 was 2.03 ton/ha and 2015 the number increased by 4.5% became 2.12 ton/ha. The average value of TFP soybean farming in Grobogan regency was 1.007. It indicated a positive progress of productivity by 0.7% in the last two years. The Productivity of Soybean will have an average value of 1.675 ton/hectare for 8 years, i.e. from 2017 until 2024.

Selecting high-yielding and stable genotypes is the main goal of black soybean breeding. Testing new lines in multiple environments is one of the development processes in black soybean breeding. The aims of the research were (i) to identify the effects of genotype, environment, and their interactions (GEIs) on the grain yield of soybean lines in Java Island; (ii) to select stable and high-yielding soybean lines; (iii) to determine the discriminative environments; and (iv) to determine the concept of stability measurements on black soybean grain yields. Field trials of 10 new F8 promising lines and three check varieties were conducted under eight different environments during four years (2016–2019). The measurement results showed that the grain yield was influenced by genotype (8.35%), environment (59.49%), and GEIs (32.16%). Grain yield stability measurements showed that the four newly identified lines had high yields and were stable in eight environments; they were A-5A-PSJ (S2), D...
Grain yield stability of black soybean lines across three agroecosystems in West Java, Indonesia
Open Agriculture
Black soybean (Glycine soja (L.) Merril) is one of the potential agricultural commodities in Indonesia. The multilocation trial is the primary requirement for variety release before farmers can widely use the new varieties. Various stability measurements on grain yields will provide more accurate information in selecting superior lines. The aims of the study were to: (i) identify the effect of genotype by environment interactions (G×E) on black soybean grain yields; (ii) select the black soybean lines with stable and high grain yields in different agroecosystems; and (iii) determine the best representative environment for testing black soybean lines. The field trials used an augmented design that was applied in three blocks for each location. The research was conducted in West Java, Indonesia, specifically in Sumedang, Indramayu, and Majalengka. The three locations are traditionally soybean production areas in West Java. The results showed that G×E significantly affected grain yield...
