The researchers studied how different combinations of forage sorghum and legumes (cowpea and guar) affect the productivity and quality of forage crops. They found that planting sorghum with cowpea or guar in a 1:1 or 2:1 ratio resulted in the highest green fodder and dry matter yields. Sorghum planted with guar in a 1:1 ratio had the highest protein content, while planting sorghum with legumes in a 1:1 ratio led to lower fiber content. Overall, planting forage sorghum with legumes in specific ratios can increase both the yield and quality of the crops.
