Abstract
Intercropping is the most prevalent farming system in the developing countries to intensify and sustain the farm productivity A research experiment on the legumes intercropping in sorghum based farming system was conducted to study the effect of legumes on the production of sorghum The data revealed that legumes intercropping has a substantial effect on the growth and grain yield of sorghum Data on maturity period of sorghum indicated that planting pattern had no consistent effect on the maturity of sorghum crop However, legumes intercropping showed non-significant effect on the days taken to maturity by sorghum. Moreover, planting pattern and legumes intercropping had significantly affected the number of grains panicle' of sorghum Double row strips planting pattern and sole sorghum gave significantly more number of grain panicle" compared to other treatments. In both the years of study, double row strips planting pattern significantly increased the grain yield of sorghum than single rows and triple row strips planting pattern. The grain yield of sole sorghum was significantly more than the grain yield of sorghum associated with mung bean or guar Moreover, in the first year of study, protein content of sorghum grain was not significantly affected by the planting pattern but in the second year of study, double and triple row strips planting pattern significantly increased the protein content than single rows planting pattern having a protein content of 9.19%. Sorghum grain protein content of 9.51 and 949% produced in the association of mungbean during 1999 and 2000, respectively was significantly more than the grain protein content of sole sorghum or sorghum grown in the association of guar. The interaction between planting pattern and legume intercropping as regards protein content of sorghum grain was non-significant.
