Effect of moisture regimes in conjunction with nitrogen levels on consumptive use in summer sunflower, Helianthus annuus L.

摘要

Results of an experiment on sunflower conducted at Water Management Project Farm, Gujarat Agricultural University, Navsari during summer seasons of 1994, 1995 and 1996 revealed that the highest consumptive use of water was 520 mm with I_(1.0) level.Lesser irrigation in treatment I_(0.6) reduced the consumptive use by 33 percent and yield by 9.8 percent compared to I_(1.0) treatment. There was no noticeable effect of nitrogen application on consumptive use of water in sunflower.
