Abstract

The yield and agronomic responses of Florence x Aurore 188-67 variety as affected by different rates of irrigation, nitrogen fertilization and seeding were studied during the 1967 season in the upland field of U. P. College of Agriculture.

Irrigation generally increased the height of plants, number of productive tillers, number of seeds per spike, weight of 200 grains, grain and straw yields but delayed heading. Irrigation at 5 cm. per week regulated in decreased harvest index but with 10 cm. per week, harvest index increased. Except for this traits, the optimum irrigation for the most of the characteristics was 5 cm. per week.

Nitrogen application increased plant height, number of productive tillers, number of seeds per spike, grain and straw yields but not seed weight and harvest index. The optimum rate of nitrogen application was 45 kg. per hectare. Heavier seeding rate induced earlier heading, increased productive tillers but decreased the number of seeds per spike. The seed rates used failed to affect differentially other characters studied.

The optimum combination of these factors for best wheat production consist of irrigation at 5 cm. per week, nitrogen application at 45 kg. ha. and possibly a seed rate of 100 kg. per ha.
