Yield attributes and yield of various varieties of wheat under different dates of sowing in rice based cropping system in Chhattisgarh

Abstract

A field experiment was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur during rabi season of 2011-2012 to find out suitability of various varieties of wheat under different dates of sowing in rice based cropping system in Chhattisgarh. The experiment was laid out in a Split plot design with five sowing dates (26 November, 06 December, 16 December, 26 December and 05 January) and four varieties (Kanchan, GW-273, Sujata and Amar). The results of experiment reveals that maximum numbers of grains/ ear head were observed in earlier sowings as compare to delay sowing highest value of observed in D1 in the variety GW-273 (43.9) and Kanchan (35.7). Dates of sowing significantly influenced grain yield (kg/ha) in different varieties. Maximum grain yield was observed in D1 as compare to delayed sowings (D2, D3, and D4). Under the D1 the grain yield was observed maximum in Sujata and minimum in Kanchan.
