Abstract
A field experiment was conducted during kharif 2015-16 and 2016-17 at the Regional Research Station (Old Alluvial Zone), Dakshin Dinajpur under Uttar Banga Krishi Viswavidyalaya to study the effect of seed priming and foliar application of micronutrients on direct seeded upland rice (Oryza sativa L). The experiment was laid out in factorial randomized block design with nine treatment combinations comprising seed priming and foliar spray of micronutrients. Treatments were replicated thrice. Significantly highest yield (3667.03 kg ha-1) was recorded in seed priming with 2.2% CaCl2. This priming treatment also had greater impact in production economics (return rupee-1 of investment is 1.45) of direct seeded rice. The rice seed priming with water showed poor productivity leading to less remuneration. Foliar spray with chelated zinc and solubor at 35 and 55 DAS respectively showed improvement in yield components and yield of direct seeded rice (3546.98 kg ha-1) compared to sole application of chelated zinc and solubor at 35 and 55 DAS. Return rupee-1 of investment (1.42) was highest when direct seeded rice crop received two foliar spray with chelated zinc and solubor at 35 and 55 DAS. No remarkable changes have been observed in pH, available N, P2O5 and K2O status in the soil after two years of the experiment.
