Yield, Quality and Economics of Various Rice Varieties of Telangana as Affected by Saline Irrigation Water under Different Agronomic Management Options

Aim: To evaluate the impact of saline irrigation water on yield, quality and economics of various rice varieties under different agronomic management options.

Study Design: The experiment was laid out in strip-plot design with three replications.

Place and Duration of Study: At College Farm, College of Agriculture, Rajendranagar, Hyderabad, during kharif, 2018.

Methodology: After the preliminary layout, local variety of dhaincha was broadcasted in the experimental site with seed rate of 40 kg ha-1 and incorporated during initiation of flowering in the respective treatment plots. Farm Yard Manure (FYM) (10 t ha-1) was applied and thoroughly mixed with the soil. Four rice varieties RNR-15048, KNM-118, JGL11118 and CSR-36 were were choosen because of its popularity in Telangana and raised well in advance and transplanted in respective treatments.

Results: The highest grain and straw yield was recorded by CSR 36 followed by (fb) RNR 15048 in combination with GM (In situ green manuring), Among the varieties, the highest amylose content was registered by JGL 11118 (24.16%) followed by RNR 15048 (21.9%). The highest L/B ratio was recorded by RNR 15048 (3.33) which was significantly higher than CSR 36 (3.20) and JGL 11118 (3.13). The highest head rice recovery was observed in CSR 36 which was on par with RNR 15048. In situ green manuring in RNR 15048 variety of Telangana received higher income. Under control treatment only the recommended dose of fertilizers (120:60:40 kg ha-1) was applied.

Conclusion: GM should therefore be done under saline water irrigation in registering superior yield, quality and economics in RNR 15048 in the district of Telangana.
