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

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.
