International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities<br />

during 22-24, December 2022 at ICAR-CRIDA, Hyderabad<br />

Results<br />

Chickpea sown at MW 38 (S 1) (Uttara Nakshatra) produced a significant maximum grain yield<br />

(850.79 kg ha -1 ) and total monetary returns (Rs. 35247 ha -1 ) over S3 and S4 sown crop as<br />

discussed in the table below i.e. MW 42 and 44 (Chitra and Swati Nakshatra). Results are in<br />

close agreement with the finding <strong>of</strong> InduBalaSethi et al, (2016). Variety Digvijay produced<br />

more grain yield (719.87 kg ha -1 ), and total monetary returns (Rs. 29646 ha -1 ) over variety<br />

Vijay. This might be due to the efficient utilization <strong>of</strong> available soil moisture. . Parmar et al.<br />

(2015) revealed that maximum grain yield was recorded from early sown whereas minimum<br />

yield was obtained from the late sown crop <strong>of</strong> chickpea.<br />

The average CUM (288 mm) was recorded higher by the S 1 sown crop (MW 38 (Sept. 17-23),<br />

Uttaranakshatra) and MUE (3.7 kg ha -1 mm) was recorded higher by the S1 sown crop (MW<br />

38 i.e. Uttara sown crop). Among the varieties Digvijay recorded the highest average value <strong>of</strong><br />

CUM and MUE as shown in Table. The yield was decreased if Tmax increases above 31.8 0 C.<br />

The Tmin <strong>of</strong> 18.3 0 C was found to be optimum for getting higher grain yield and thereafter<br />

there was a decrease in chickpea yield.<br />

Pooled grain yield (kg ha -1 ) and total monetary returns (TMR) (Rs ha -1 ) <strong>of</strong> rabi chickpea<br />

as influenced by various sowing dates and varieties. (2016 to 2020)<br />
