Abstract

Field experiments were done in 2018 and 2019 at Fedis and Erer to determine the effect of intercropping sorghum with soybean on grain yield. Seed yields were higher in the sole crops of sorghum and soybean than in the individual components of the intercrops. This is due to the crops' compete of nutrients, light, water, and other factors. The yields of the intercrop's component crops varied greatly depending on the variety. The sorghum/soybean ‘Teshale/Awasa-95’ intercrops were more productive than the sorghum/soybean ‘Dhaqaba/Awasa-95’ intercrops, which had an LER (land equivalent ratio) of 1.14. Intercropping sorghum ‘Teshale’ with soybean ‘Awasa-95’ resulted in maximum grain production and LER greater than one, showing that intercropping has an advantage over solely planting. As a result, intercropping sorghum and soybean is compatible, desirable, and more advantageous for increasing production than solely cropping under the same conditions.

Abstract

Groundnut is a versatile and economically significant plant that has played a prominent role in human history. Using additive main effects and multiplicative interaction analysis, the performance of 12 groundnut genotypes was assessed in six environments across four sites. Highly significant genotypes and GE interactions were found in the mean squares of the analysis of variance for seed yield per hectare. Environment-related differences made for 53.25% of the overall variation, whereas genotype was responsible for 43.73% of it. For 84.93% of the overall variation, the biplot was responsible. The most stable models according to the AMMI model were 19748 and 19750. As a result, these genotypes are thought to be the most suitable ones for the study locations. The candidate variety 19748 is stable and high yielding, with a yield advantage of about 18 percent above the standard check Babile-2.Then suggested to release and further multiply as a commercial variety at study and similar agro-ecology.
