MANAGEMENT OF PARASITIC WEED (OROBANCHE) IN MUSTARD (Brassica juncea L.) FOR WCE AND YIELD ENHANCEMENT
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 46
Abstract
The present investigation was conducted at Gwalior during rabi 2011-12 entitled management of parasitic weed (Orobanche) in mustard (Brassica juncea L.) for weed control efficiency (WCE) and yield enhancement. The results showed that, application of Pendimethalin 1.0 kg/ha pre-emergence resulted in lowest weed density (81.3/m2), weed dry weight (13.6 g/m2) and highest weed control efficiency (86.98%). While highest orobanche control efficiency (37.22%) and lowest weed density (0.33/m2) was noted under the treatment trifluralin at the rate of 1.5 kg/ha + neem oil 1% pre-plant incorporation. As concern with yield and yield attributes, the treatment pendimethalin at the rate of 1.0 kg/ha pre-emergence recorded highest seeds/siliqua (15.16), test weight (4.76 g) and seed yield (22.22 q/ha) which was similar with the treatments trifluralin at the rate of 1.5 kg/ha + neem oil 1% pre-plant incorporation, application of neem cake at the rate of 200 kg/ha in furrow and pendimethalin at the rate of 0.5 kg/ha pre-emergence followed by 1 hoeing at 40 days after sowing (DAS) and significantly superior over rest of the treatments under study. The treatment pendimethalin at the rate of 1.0 kg/ha pre-emergence was found to be cost effective with net returns of Rs. 51350 and B: C ratio 4.36 which was followed by the treatment trifluralin at the rate of 1.5 kg/ha + neem oil 1% pre-plant incorporation. Hence for effective control of Orobanche and other associated weeds, application of pendimethalin at the rate of 1.0kg/ha pre-emergence can be the best option which was followed by trifluralin at the rate of 1.5 kg/ha + neem oil 1% pre-plant incorporation for higher WCE and yield in Indian mustard.
