Abstract

The present investigation was carried out at rice research farm of College of Agriculture, Central Agricultural University, Imphal in kharif season of 2019 at polyhouse to study the effect of chemical priming treatments on yield attributes of rice varieties. Treatment consists of three variety of rice viz. CAU-R1, keibu-chiro and Kiophou and two priming chemicals viz. 2% KNO3, and 50 ppm Salicylic acid with one control (no priming). Water stress were created in each pot by maintaining soil moisture level at 32% by using soil moisture meter. The results showed that highest number of effective tillers per hill (3.73), number of spikelet’s per panicle (120.93), number of filled grains per panicle (92.93), grain yield (7.07 g/hill) and straw yield (11.91 g/hill) were observed in variety CAU-R1 with treatment of 2% KNO3 (V1C1).
