Effect of weed control practices on fodder and seed productivity of Berseem in Kymore plateau and Satpura hill zone of Madhya Pradesh

Abstract

Field experiment was conducted during Rabi 2011 -12 and 2012- 13 to find out most suitable weed management practices in berseem (Trifolium alexandrinum L). Cichorium intybus, Medicago denticulata, Medicago hispida and Cornopus didymus were predominant weeds in berseem. The pre emergence application of oxyfluorfen @ 0.100 kg a.i./ha + imazethapyr @ 0.15 kg a.i./ha recorded significantly lowest total weed intensity ( 6.17/ m2 ) and dry weight (5.92 g/m2 ) of weeds as compared to other treatments. It also recorded higher weed control efficiency (72.31%). The same treatment also recorded significantly higher green fodder yield (632.9 q/ha), dry fodder yield (95.6q/ha), crude protein yield (14.878), net monetary returns (Rs. 84163) and benefit: cost ratio (2.98) as compared to other treatments after the weed free treatment.
