Effect of crop geometry and nitrogen level on growth of multicut fodder sorghum based intercropping system

Abstract

A field experiment was conducted at D block of central farm, Agricultural College and Research Institute, Madurai, Tamil Nadu during 2018-2019, to optimize the crop geometry and asses the nitrogen level for multicut fodder sorghum (CoFS-31) based intercropping system. The main plot treatments were divided with crop geometry of 30×15 and 45×15cm as sole fodder sorghum, (45+15) ×15cm and (60+30) ×15cm as paired row system with inter crop. In sub plots nitrogen level of 75, 100 and 125 per cent RDF of N were assigned. The experimental results revealed that growth parameters viz., plant height and number of tillers, were significantly increased under (60+30) ×15cm paired row system of planting with inter crop along with application of 125 per cent RDF of N.
