Abstract

Little millet crop is emerging as important crop under climate resilient agriculture and for developing functional foods for the expanding diabetic and obese population. But, the productivity of the crop is low due to its cultivation in marginal and sub marginal lands without application of fertilizers and improper crop geometry. By keeping this in view, a field study was conducted at Agricultural Research Station, Podalakur, SPSR Nellore District during rabi season 2019-20 to find out the effect of crop geometry and fertilizer levels on growth and yield of little millet. An experiment was laid out in Factorial RBD with four crop geometries (S1: 20cm × 10 cm; S2: 25cm × 10 cm; S3: 30cm × 10 cm S4: Broadcasting) as one factor and three fertilizer levels (F1: Control; F2:20-20-0 kg N, P2O5 and K2O /ha; F3: 40-20-10 kg N, P2O5 and K2O/ha) as another factor with three replications. The results revealed that among the four crop geometries the highest grain yield (1511 kg /ha) was recorded at crop geometry of 25 cm × 10 cm and the highest stover yield (2514 kg/ha) was recorded in broadcasting. Among the fertilizer levels application of 40-20-10 kg N, P2O5 and K2O /ha registered significantly higher grain (1485 kg/ ha) and stover yield (2679kg/ha). Little millet grain yield was significantly influenced by crop geometry and fertilizer levels interaction. Significantly the highest grain yield (1833 kg ha-1) was recorded at crop geometry of 25 cm × 10 cm with application of 40-20-10 kg N, P2O5 and K2O/ha.

Conclusion

The present investigation revealed that, crop geometry of 25 cm × 10 cm and application of 40-20-10 kg N, P2O5 and K2O/ ha was found to be optimum for realizing higher grain yield in rainfed vertisols of Southern agro climatic zone of Andhra Pradesh.
