Abstract
Two sorghum varieties, Darso and Feterita, were subjected to three nitrogen rates and three population densities. The experiment was conducted during the dry season (1967) and during the wet season (1968) at the Central Experiment Station, U. P. College of Agriculture.
Heading for Feterita was earlier than Darso during the dry season but later during the wet season. While Darso was not affected by season, Feterita prolonged the vegetative phase which would account for taller plants during the wet season. As nitrogen increased from 50 to 100 and 150 kilograms per hectare, heading was hastened.
Grain yield for Darso was higher than Feterita during the dry season. Nitrogen treatments, 100 and 150 kilograms, gave significantly higher yield than the 50-kilograms rate. Grain yield was also increased during the dry season as plant population increased from 100,000 to 150,000 and 200,000 plants per hectare.
