Abstract
The influence of nitrogen nutrition and population density on yield and yield components of two sorghum varieties was studied during the dry season (1967 and wet season (1968), at the upland field of the Central Experiment Station, U. P. College of Agriculture.
Darso consistently gave a significantly higher grain yield (5.46 and 4.62 tons) than feterita (4.38 and 3.9 tons) in both seasons. Both varieties responded to nitrogen treatments only during the wet season with the 100 kilogram nitrogen rate significantly higher than the nitrogen rate. The 200-kilogram rate gave only a slight increase in yield over the 100-kilogram rate. Nitrogen also enhanced maturity for both varieties during the wet season.
Increasing population from 100- to 200- and 300-thousands plants per hectare increased yield for Darso in both seasons. Yield for feterita increased with increasing population level during the dry season but decrease during the wet season.
