Description Planting of the main season (kharif 1976) started on June 23 and continued until July 29. The delayed planting for. advancing generations was done on September 3. The early maturing types were planted in red soil at a row to row distance of 75 cm and medium and late maturing at 150 cm in black soil. Fertilizer was broadcast before bridging at the rate of 18 Kg N and 46 Kg P2 O 5 / h a . This year nine isolation blocks were established along the
western boundry of the farm to advance germplasm group composites without selection. No fertilizer was applied to these blocks. Planting was delayed until there was sufficient moisture in the soil (about 6 inches of moist soil). Precipitation during the season (742.5 mm) was slightly below the normal precipitation of 760 mm (Table 1 ). August rainfall was unusually heavy, resulting in some waterlogging, and September rainfall was below normal.
To make up for the early cessation of the monsoon, one irrigation was given in mid-November to part of the crop on black soil. Unfortunately just after the irrigation there was some rain with strong wind which caused considerable lodging and flower and young pod drop in medium maturing types. In red soil plant stand was adversely affected by high Sclerotium rolfsii incidence at the seedling stage and by Phytophthora (stem blight) later on. Undecomposed organic matter from the previous pearl millet crop seems to have accentuated the Sclerotium rolfsii incidence. Observations on stem blight incidence indicated genotypic differences for susceptibility. Most of the breeding material was grown in pure stand. However, two breeding populations and a trial on black soil were in maize intercrop and a trial on red soil was in
Setaria intercrop. Incidence of insect pests was high throughout the season. Insecticide sprays were applied by the plant protection unit on the recommendation of entomologists. Off-site plantings included early maturing material at Hissar and late maturing material at Gwalior.
