Effect of inorganic fertilizer and crop residue on yield attributes and yieldof rice (Oryza sativa L.) Vr. Pusa Basmati- 1121

Abstract

A field experiment was conducted during Kharif season of July 2013 and 2014at crop research farm SHIATS Allahabad to study the effect of inorganic fertilizer and cropresidue on yield attributes and yield of rice. Treatments were arranged using (4x3) factorial R.B.D with three replications. The crop was harvested at maturity data on plant ht. (cm.), no. of tillers, no. of effective tillers; panicle length (cm.), test wt. (g.), grain yield (q/ha.) and straw yield (q/ha.) were recorded. Plant ht., no. of tiller, no. of effective tiller, test wt., grain yield and straw yield was found significantly increased by different levels of doses. Maximum plant ht. was observed (86.10 cm and 87.89 cm.), no. of tillers (22.38 and 25.00), no. of effective tiller (12.29 and 13.33), panicle length (28.75 and 28.94 cm.), test wt. (23.33 and 23.64 g.), grain yield (39.54 and 41.78 q/ha.) and straw yield (87.45 and 91.23 q/ha.) by different levels of inorganic fertilizerand different levels of wheat residue retention in 2013-14 showed Plant ht. (83.19 and 84.17 cm.), no. of tillers (21.68 and 22.42), no. of effective tillers (10.70 and 10.75), panicle length (28.23 and 27.89 cm.), test wt. (23.33 and 23.64 g.), grain yield (34.75 and 36.41 q/ha.) and straw yield (84.08 and 79.26 q/ha.) in both the years of experiment 2013,14 respectively.
