RESPONSE OF INDIAN MUSTARD (BRASSICA-JUNCEA) TO DIFFERENT PRODUCTION FACTORS IN RECLAIMED RAVINE LAND OF THE RIVER YAMUNA

A field experiment was conducted during the winter season (rabi) of 19 91-92, through 1992-93 in reclaimed ravine land of river Yamuna at Agt a to study the response of Indian mustard [Brassica juncea (L.) czernj & Cosson] to various production factors for achieving the higher yiel d and net returns. Combined application of different production factor s (irrigation, fertilizer, farmyard manure and plant protection) under high input management recorded the highest increase in growth, yield and yield attributes. Mustard yield increased by 58% with 1 irrigation given at branching, 82% with 2 irrigations given at branching and flo wering, and 101% with 3 irrigations given at branching, flowering and pod filling. Yield further increased by 118% with additional applicati on of 60 kg N/ha and 135% with further additional application of 10 to nnes farmyard manure/ha over low input management (control). The highe st yield (2 268 kg/ha) and the highest additional net returns (Rs 8 82 3/ha) were recorded under high input management.
