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).

A systematic survey of 240 soybean growers on adoption of herbicide application practices was conducted in Akola, Buldana, Washim, Amravati, Yavatmal and Wardha districts of Vidarbha during 2013-14 as University Research Review Committee Project. The study revealed that out of 240 selected farmers 221 (92.08%) farmers applied herbicide in soybean crop. Knowledge about the recommended per ha doses of herbicides was not known to 57.08 % farmers. Power spray is never used for spraying of herbicides was not known to 29.17 % farmers in study area. Knowledge about calibration of spray pump was not noted in majority (97.08%) farmers. Use of 500 L water per ha for herbicide application in Soybean crop is not known to more than three fourth (77.50%) per cent farmers. Overall majority 61.25 % farmers have medium level of knowledge about selected 14 herbicide application practices for soybean crop. In selected districts Imazethapyr were more popular among majority (78.28 %) herbicide adopters in soybean crop, followed by 15.85 % farmers used Imazethapyr + Imazamox. Knapsack sprayer used by 61.54% farmers and power sprayer used by 38.46 % farmers for application of herbicides in soybean. Out of the total 85 (38.46%) power sprayer users majority 73 (85.88 %) farmers have not get effective control over weeds in soybean crop. Majority 88.69 % adopter farmers used less than recommended 500 liters of water/ha for herbicide application in soybean. Use of power sprayer and low quantity of water maintained at the time of herbicide application may be the causes of poor results at farmer’s level.

An investigation was carried during the year 2018-19 to study the“ Effect of tillage and weed management practices on physico-chemical properties of soil and yield of soybean in Inceptisols” at Research Farm of All India Coordinated Research Project (AICRP) on Weed Management, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The study has focused the integrated effect of tillage and weed management practices on physico chemical properties of soil, yield of soybean and availability of nutrients. Five weed control practices were superimposed in four strips of different tillage practices in strip plot with three replications. The tillage operations consist of conventional tillage, reduced tillage, minimum tillage and zero tillage, however weed management practices includes application of pre emergence weedicide (diclosulam), post emergence weedicides (propaquizafop + imazethapyr.), integration of pre emergence and post emergence weedicide, hand weeding and weedy check. The soils of experimental plot was alkaline in reaction and low to medium in organic carbon. The available nitrogen and phosphorus was low and potassium was high to very high. Based on the observations noted, the bulk density of soil was significantly influenced due to tillage and weed management practices. The highest bulk density was noted with zero tillage (1.46 Mg m-3) followed by reduced tillage (1.45 Mg m-3). The highest Mean Weight Diameter (0.75 mm) was enumerated with minimum tillage and hand weeding management practice (0.75 mm). While, the interaction of tillage and weed management practices showed non-significant results in respect of soil physical properties. The highest available of nitrogen (207.33 kg ha-1), phosphorus (20.07 kg ha-1) and potassium (346.1 kg ha-1) were recorded with minimum tillage and with hand weeding practice.

Background: Among the different production factors, irrigation and nutrient management are of immense importance in Pigeon pea cultivation. Drip irrigation can be considered as an efficient irrigation system to maintain optimum moisture content in the root zone. Split application of fertilizers at appropriate stages of crop growth ensure a regular flow of both water and nutrients resulting in increased growth rate and higher yield. Fertigation proposed as a means to increase efficient use of water and fertilizer to increase yield and sustained irrigated agriculture. The current study aims to study the efficacy of split application of N, P and K on growth, water and nutrient use efficiency, productivity and profitability of Pigeon pea.Methods: The field experiment was conducted at Department of Agronomy Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during three consecutive kharif season of 2016-17, 2017-18 and 2018-19. The experiment was laid out in randomised block design with four replications and eight treatments with an objective to study the efficacy of split application of nutrients on growth, water and nutrient use efficiency, productivity and profitability of Pigeon pea. Result: The results revealed that, all the growth parameters, yield attributes and grain yield of Pigeon pea were substantially enhanced by drip fertigation levels at 125:100:100 per cent recommended NPK than lower fertigation levels (75 and 100%) and over conventional soil application of recommended dose of NPK kg ha-1. Drip fertigation at 125:100:100 per cent recommended dose of NPK ha-1 recorded higher pigeon-pea pooled grain yield of 4053 kg ha-1. The maximum GMR (Rs.226807 ha-1), NMR (Rs.176604 ha-1), B:C ratio (4.52) and highest economic efficiency of Rs.883 day-1 ha-1.
