Abstract

Growing concerns about the environment have made better use of natural resources, less use of chemicals, and more efficient irrigation water use increasingly important goals of sustainable agriculture. As a result, an experiment was conducted during the summer season of 2019 at College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Rajasthan, India. The treatments consist of 2 levels of irrigation viz., 0.60 and 0.80 PE and two interval levels viz., alternate and 3 days in main plot and three groundnut cultivars viz., HNG-69, HNG-123 and TG-37-A in sub plot. The experiment was laid out in split plot design and replicated thrice. The yield of crop evaluated as pod yield, haulm yield, biological yield and test weight and in terms of water economy water use, water use pattern and water use efficiency. Results revealed that higher pod yield (3117 kg ha-1), kernel yield (2147 kg ha-1), haulm yield (4081 kg ha-1), biological yield (7199 kg ha-1), test weight (446.58 g),

Keywords

haulm yield, kernel yield, biological yield, water use efficiency.

Conclusion

HNG-123 produced significantly higher Karnal, haulm and biological yields, and a higher water use efficiency and net return with irrigation at 0.80 PE at alternate day irrigation intervals.
