Abstract

The field experiment was conducted to study the Pigeon Pea varieties AL 882 and Pusa Arhar 16 under different spacing in Amritsar region of Punjab during kharif 2019-2020 at Student’s Research Farm, Department of Agriculture, Khalsa College, Amritsar, Punjab. Two varieties V1 (Pusa Arhar 16) and V2 (AL 882) were tested under different spacing S1 (30 ×12.5), S2 (40 × 12.5), S3 (50 × 12.5), S4 (30 × 25), S5 (40×25), S6 (50×25cm) in Factorial Randomized Block Design and replicated thrice. The primary limitations in pigeon pea cultivation in Punjab are cultivar selection and optimal spacing. The results revealed that cv. AL 882 performed better under spacing 30×12.5 cm for growth parameters such as plant height and LAI whereas dry matter accumulation, crop growth rate and number of primary and secondary branches were significantly higher in spacing 50×25 cm. Quality parameters recorded non-significant results under different spacing and varieties. Among yield parameters, seed yield, harvest index, net returns and benefit cost ratio were maximum in wider spacing 50×25cm and narrow spacing 30×12.5 cm with cv. AL 882 and cv. Pusa Arhar 16, respectively. However, both varieties produced highest stover yield and biological yield under narrow spacing 30×12.5 cm.

Conclusion

With regard to the quantitative measure of seed yield, the recently introduced cultivar Pusa Arhar 16 exhibited superior performance when cultivated under a narrower spacing regime of 30 cm × 12.5 cm, in comparison to the cultivar AL 882 which performed better when cultivated under a wider spacing regime of 50 × 25 cm. Nonetheless, when assessing the economic profitability of the two cultivars in the specific agro-climatic conditions prevalent in Amritsar, it was observed that the cultivar AL 882 proved to be economically more viable than Pusa Arhar 16, taking into account the total net returns generated from both seed and stover.
