Abstract
A field experiment entitled “Studies on sustainable modules for year round green fodder production under irrigated condition” was conducted during kharif, rabi and summer seasons of 2018-19 and 2019-20 at Zonal Agricultural Research Station, Vishweswaraiah Canal Farm, Mandya. The experiment was laid out in randomized complete block design with fifteen fodder cropping system modules and replicated thrice. Pooled data revealed that, perennial system of B×N hybrid + Lucerne (2:8) recorded
significantly higher green fodder yield (1636 q ha-1 year-1), dry fodder yield (321 q ha-1 year-1), carbon sequestration (24.87 Mg ha-1) and net returns (Rs. 2,14,232 ha-1 year-1) followed by B×N hybrid + Cowpea (2:8) (1552 q ha-1 year-1, 308 q ha-1 year-1, 24.35 Mg ha-1 and Rs. 1,96,354 ha-1 year-1, respectively) and B×N hybrid + Sesbania (2:8) systems (1440 q ha-1 year-1, 313 q ha-1 year-1, 24.49 Mg ha-1 and Rs. 1,66,528 ha-1 year-1, respectively). However, B×N hybrid + Sesbania (2:8) system resulted higher quality fodder interms of crude protein (61.8 q ha-1 year-1), ash (35.0 q ha-1 year-1) and ether extractable fat yield (11.8 q ha-1 year-1) but which was found on par with B×N hybrid + Lucerne (2:8) (60.2, 34.8 and 10.5 q ha-1 year-1, respectively) and B×N hybrid + Cowpea (2:8) systems (56.0, 34.6 and 9.3 q ha-1 year-1, respectively). Thus, farmers can adopt B×N hybrid + Lucerne (2:8) or B×N hybrid + Cowpea (2:8) or B×N hybrid + Sesbania (2:8) systems as a viable and profitable module for year round fodder production.
