Background: Groundnut encounters severe infestation of weed especially during the early stages of growth due to less crop canopy which allows higher weeds growth and thus crop becomes more susceptible to weed competition. During rainy season, effective and economical weed control is not possible through manual and mechanical weeding due to unfavorable soil conditions and also the unavailability of costly labours. Herbicides have been accepted as cost effective tool to manage weed menace in groundnut. The current study aims to study the efficancy of different post-emergence and pre-mix combination of post-emergence herbicides on weeds, growth and yield of groundnut. Methods: The field experiment was conducted at AICRP Weed Management field, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) during three consecutive Kharif seasons of 2015- 2017. The experiment was laid out in Randomized Block Design with ten treatments replicated thrice. The treatments comprised of one pre emergence and five different post emergence herbicides and compared with weed free and weedy check. Result: The results revealed that weed free was found most effective to control weeds in groundnut with lowest weed count, weed dry matter of weeds and maximum gross monetary returns (Rs.117641/ha), net monetary returns (Rs.80894/ha). Among the herbicides, application of Imazethapyr + Imazomox 0.10 kg /ha POE 20 DAS produced less weed count and weed dry matter and highest weed control efficiency (80.68%) and lower weed index (6.71% ) as well as maximum growth, yield attributes and pod yield in groundnut over all the other herbicidal treatments viz. plant height (30.25), dry matter accumulation (18.11g), number of pods/plant (32.35) and pod yield (2448 kg/ha) and highest pooled B:C ratio (3.74).

An experiment was conducted on "Productivity and quality dynamics of parching sorghum genotypes as influenced by nitrogen management through vermicompost during rabi season" of 2018-19. The results revealed that among the parching sorghum genotypes, Gulbhendi Local-1 showed significantly higher growth attributes viz., plant height, dry matter plant -1 and stem diameter as compared to genotype Phule madhur at harvest. However, the parching sorghum genotype Phule madhur showed significantly more number of leaves, leaf area plant -1 and leaf : stem ratio over genotype Gulbhendi Local-1. With reputes to yield attributes, the parching sorghum genotype Phule madhur recorded higher green hurda yield over the genotype Gulbhendi Local-1 and found significantly superior of the parching sorghum genotype Gulbhendi Local-1. However, the genotype Gulbhendi Local-1 recorded maximum green fodder yield and found significantly superior over the genotype Phule Madhur. The highest benefit: cost ratio was observed in Phule Madhur as compared to Gulbhendi Local-1 genotype. With regards to nitrogen management at harvest, application of 125% RDN ha -1 through vermicompost recorded superior growth as well as yield attributes along with optimum B:C ratio and was found significantly superior over 100 percent RDN ha -1 through vermicompost, 50 per cent RDN ha -1 through vermicompost and control, respectively. The experimental consequences revealed that with reputes to quality analysis of grain the parching sorghum genotype Phule Madhur found superior over Gulbhendi Local-1. Similarly, the results revealed that in respect of proximate analysis, the fodder from Gulbhendi Local-1 found superior over Phule madhur with respect to crude protein, crude fibre, Ether Extract and total ash. However, the genotype Phule Madhur found better in producing Nitrogen free extract. In respect of quality and proximate analysis, application of 125% RDN through vermicompost also proved significantly superior over other nitrogen management treatments.
