Response of Different Rice Varieties and Fertility Levels on Relative Economics and Quality of Rice under Aerobic Conditions

Abstract

The study was undertaken at Research Farm of Division of Agronomy, SKUAST-J, Chatha. The experiment was laid out in factorial randomized complete block design with four varieties viz. PR-115, DRRH-3, PAC-837 and PR-121, as one factor and four fertility levels viz. 0:0:0, 90:45:22.5, 120:60:30 and 150:75:37.5 kg N-P2O5-K2O ha-1, as second factor with three relications. The results revealed that among four varieties, variety PAC-837 recorded highest grain and straw yield. The quality parameters, Length: Breadth (L:B) ratio before cooking was recorded highest in PR-115 and L:B ratio after cooking was recorded highest in DRRH-3. Protein and amylose content were found higher in variety PAC-837. Rice variety PAC-837 also recorded higher net returns (Rs. 4002.28) and B:C ratio (1.24). Amongst the fertility levels, the application F4: N150P75K37.5 kg ha-1 fertility level recorded highest grain and straw yield over other fertility levels. Quality parameters viz. L:B ratio before cooking and after cooking, protein and amylose content also followed the similar trend, B:C ratio (1.52) was higher in F3: N120P60K30 kg ha-1. On the basis of quality and relative economics it may be recommended that rice variety PAC-837 found ruminative with application of F3: N120P60K30 kg ha-1 fertility level.
