Weed indices and economics of bajra Napier hybrid as influenced by weed management practices

Abstract

An experiment was conducted to standardise an economic weed management strategy for Bajra Napier Hybrid in the variety of BN hybrid Suguna.The experiment was laid out in randomized block design (RBD) with 9 weed management treatments in three replications. Among the weed management practices, application of oxadiargyl 90 g ha-1 on 3-5 DAPfb hand weeding on 25 - 30 DAP (T5) recorded the lowest weed count, relative density, dry weight and the highest weed control efficiency at 25 and 50 DAP. The highest green fodder yield (154.84 t ha-1), dry fodder yield (30.96 t ha-1) and the lowest weed index was recorded in T5. The highest net returns of ₹ 123758.5 ha-1 and significantly higher B:C ratio (1.66) was obtained in T5 suggesting that the treatment T5 (oxadiargyl@ 90 g ha-1 on 3-5 DAPfb hand weeding on 25-30 DAP) could be adjudged as the economic weed management practice in Bajra Napier hybrid.
