Effect of sowing time on grain yield of wheat. Bars are mean ± SE of three replications. Bars sharing same letter don’t differ significantly.
Relationship between (a-e) sowing time and emergence count (plants m-2), and (f-j) sowing time and number of tillers m-2 during 2011-12 to 2013-14. Coefficients of determination (R2), significance of coefficients (P < 0.05) and dependence of (a-e) emergence count m-2 (y) and (f-g) number of tillers m-2 (y) on sowing time (x) are given (n = 4).
Relationship between (a-e) sowing time and 1000-grain weight (g), and (f-j) sowing time and number of grains spike-1 during 2011-12 to 2013-14. Coefficients of determination (R2), significance of coefficients (P < 0.05) and dependence of (a-e) 1000-grain weight (y) and (f-g) number of grains spike-1 (y) on sowing time (x) are given (n = 4).
