Abstract

A field trial was conducted during the kharif seasons of 2021 and 2022, at University of Agricultural Sciences, GKVK, Bengaluru, Karnataka. The aim of the study was to investigate the agronomic performance of two varieties each in foxtail millet, proso millet and little millet across three sowing windows viz., second fortnight of august (W1), first fortnight of September (W2) and second fortnight of september (W3). There were 18 treatments with three replications each, tested in a factorial randomized design. In the study, significant variations were observed in absolute growth rate, crop growth rate and relative growth rate. Sowing during August second fortnight has recorded higher absolute growth rate (0.4810 g/day), crop growth rate (10.05 g/m2/day), relative growth rate (0.0174 g/g/day) at 60 DAS-at harvest. Among the crops, higher absolute growth rate (0.4286 g/day), relative growth rate (0.0185 g/g /day-) and crop growth rate (9.33 g/m2/day) were recorded in foxtail millet at 60 DAS-at harvest. Among varieties DHFt 109-3, GPUP-21 and GPUL-6 recorded higher AGR, CGR and RGR than GPUF-3, GPUP-28 and DHLM-36-3 at 60 DAS-at harvest. Foxtail millet consistently displayed higher values in several parameters, with DHFt-109-3 sown during second fortnight of august was showing superior performance in terms of AGR (0.5348 g/day), CGR (10.96 g/m2/day) and RGR (0.0207 g/g/day) at 60 DAS-at harvest. Proso millet demonstrated the early maturation, while little millet showed relatively late performance across different sowing windows

Conclusion

Sowing during August second fortnight has recorded higher absolute growth rate, crop growth rate, relative growth rate while lower absolute growth rate, crop growth rate relative growth rate was recorded in September second fortnight sowing. Among the crops, higher AGR, RGR and CGR were recorded in foxtail millet whereas, lower absolute growth rate, crop growth rate and relative growth rate was recorded in little millet. Among varieties DHFt 109-3, GPUP-21 and GPUL-6 recorded higher AGR, CGR and RGR than GPUF-3, GPUP-28 and DHLM-36-3. The combination of sowing of DHFt 109-3 variety of foxtail millet during second fortnight of august has recorded significantly higher AGR, CGR and RGR. Lower AGR, CGR and RGR was observed with combination sowing of DHLM 36-3 variety of little millet during second fortnight of September at 60 DAS-harvest. NAR showed non-significant responses with respect to sowing windows, crops and varieties
