The experiment was conducted with 13 treatment combinations involving maize, finger millet, little millet and cowpea at different proportions by using completely randomised design (CRD) and repeated three times. The results revealed that 100% Maize treatment recorded significantly higher shoot length (19.39 cm), root length (17.61 cm), seedling vigour index (3396), green biomass yield (14.10 kg m-2), crude fibre content (15.46%), crude fibre yield (0.41 kg m-2) and ash content (4.01%) and significantly lower shoot length (4.07 cm), root length (3.68 cm), seedling vigour index (713), dry weight (1.24 kg m-2), green biomass yield (9.77 kg m-2), crude fibre content (10.34%), crude fibre yield (0.13 kg m-2) and ash content (3.08%) were found in 100% Little millet at harvest. Significantly higher nitrogen content (3.79%), crude protein content (22.64%), crude protein yield (0.50 kg m-2), fat content (4.40%) were found in 100% Cowpea compared to 100% Finger millet (1.07%, 6.69%, 0.08 kg m-2 and 1.82%, respectively) at harvest. 100% Finger millet recorded significantly higher relative water content of 81.76% and water productivity of 19.19 kg litre-1 compared to 100% Maize (70.98% and 13.16 kg litre-1, respectively) at harvest. Significantly higher C:B ratio of 3.55 was found in 100% Maize.EnglishThesis
