Response of winter-season sorghum (Sorghum bicolor) varieties to sowing time and nitrogen

Abstract

An experiment was conducted during the winter season (rabi) of 1987-88 to 1989-90 to find out effect of sowing time and nitrogen on sorghum [Sorghum bicolor (L.) Moench] varieties. The pooled grain and fodder yields of sorghum varieties were not differed significantly. However, improved variety Swati gave significantly more grain yield than M 35-1 during 1988-89. But fodder yield of M 35-1 was significantly more than Swati during the same year. The pooled grain yield was significantly the highest in the crop sown in meteorological week 40 and significantly the lowest in the crop sown in meteorological week 38. Application of 50 kg N/ha at seeding significantly increased the grain yield over the control during first 2 years and in pooled data.|| In the drought-prone area of Maharashtra, al. (1991) reporf-ed that the application of 50 winter-season (rabi) sorghum [Sorghum bi- kg Nha was the most important key factor color (L.) Moench] is the predominant crop for increasing production of rabi sorghum. occupying about 60% of the area.
