An study was carried out in Kenya to assess the suitability of three promiscuous soybean varieties (SB19, GAZELLE and TGX1990-5F) intercropped with Maize (Duma 43). A randomised complete block design was used replicated three times with seven treatments. The arrangement of intercropping was 1:1. Data collection included germination %, plant height, days to 50% flowering, days to 75% maturity, yield biomass per plant, 100 grain weight, grain yield, harvest index and Land Equivalent Ratio for both crops. Shattering score, pods per plant, and seeds per pod for soybean only. Data were subjected to ANOVA and means separated using LSD 0.05 . The results showed that the earliest variety to 50% flowering and 75% maturity was SB19 (p ≤ 0.05) followed by GAZELLE while the latest variety was TGX1990-5F. Intercropping did not affect days to 50% flowering, days to 75% maturity and seeds per pod. Variety TGX1990-5F was resistant to pod shattering while others were moderately resistant. TGX1990-5F recorded the highest plant height, pods per plant, soybean biomass, grain yield and LER while GAZELLE had higher HI and SB19 recorded higher seeds per Original Research Article

An experiment was conducted in Kenya to determine the effect of intercropping maize-soybean on soybean grain quality traits. A randomized complete block design replicated three times with seven treatments was used. Data were collected and analysed for soybean protein content, oil content and dry matter while grain size was done for maize and soybean. Data were subjected to ANOVA and means separated using LSD 0.05 . The results showed that TGX1990-5F variety recorded high protein content (p ≤ 0.05) in sole crop compared to intercropping with 42.96% and 38.4% respectively while SB19 obtained 36.57% and 40.41% of protein between sites for the first season. A bout the second season, TGX1990-5F gave 40.84% of protein compared to 31.98% for GAZELLE in intercrop at both sites. GAZELLE showed higher oil content followed by TGX1990-5F and SB19 was the last in both seasons. TGX1990-5F showed higher dry matter followed by GAZELLE and SB19 was the last in intercrop. In addition, GAZELLE a local variety showed greater size than SB19 in both rainy seasons. Intercropping affected slightly the protein content, oil content and gain size than sole crop but it did not affect the dry matter in both seasons.Thus, TGX1990-5F can be recommended to small-scale farmers for intercropping with maize because it produced higher value of protein and small-scale farmers could use it to fight mal nutrition. GAZELLE variety can be also recommended for oil production. Maize grain size was not affected by intercropping system.
