Abstract
A field experiment was conducted at Agronomy farm, Khalsa College, Amritsar (Punjab) during Kharif season of 2021, to study effect of different Sowing methods FD (Flat dry sowing), BD (Beds dry sowing), Fw (flat wattar sowing), BW (beds wattar sowing) and priming methods (No priming, hydropriming and halopriming (Potassium nitrate)) on yield attributing character of rice. We concluded that maximum grain yield (72.7 q ha-1) and biological yield (167.9 q ha-1) was recorded at Fw which was at par with FD. Maximum straw yield was recorded at FD i.e., 97.1 q ha-1 which was at par with FW. Maximum harvest index was recorded at Fw i.e., 43.1 which was comparable with other treatments. On the other hand, result showed that progressive increase in the grain yield (72 qha-1) was recorded at PNi.e., Potassium nitrate which was significantly higher than others. The straw yield (95.5 qha-1) and biological yield (167.9 qha-1) were highest at PN which was significantly higher over P0 (Control) but at par with Pw (hydropriming). The maximum harvest index (42.4) was recorded at PN but at par with Pw and control. Result obtained that maximum yield attributes are recorded by using FW as a sowing method and PN as a seed treatment in rice cultivation.
