Effect of different date of sowing and crop establishment methods on performance of rice cultivars

Abstract

A field experiment was conducted at Farm of College of Agriculture, Rewa. The present investigation was carried out during the Kharif season 2020 &2021 in split plot design replicated four times. The variety used is MTU 1010. The main plot treatments i.e. Date of sowing at three different stages, at sowing time, Delayed sowing by 15 days & Delayed sowing by 30 days and sub plot treatments were broadcasting of seeds, Manual line sowing of seed, system of Rice Intensification methods, Conventional transplanting method and drum seeder. The height of the plants and number of tillers/hill were influenced Significant variation in plants height was found due different dates of sowing (Normal sowing time M1) sowed significantly greater height (28.90, 72.16and 102.16 cm) over all other dates of sowing at 30, 60 DAS/DAT and at harvest. Among the different dates of sowing Normal sowing time (M1) showed superiority with respect to panicle number and length of panicle, grain weight/panicle, test weight, which are the contributors of grain yield Among the cost of cultivation varied due to different dates of sowing (Normal sowing time M1) (Rs. 28800.8/ha), Delayed sowing by 15 day (M2)(Rs. 28500.8/ha) and Delayed sowing by 30 day(M3) (Rs. 28300.8/ha).
