: A field experiment was conducted on summer sesame during summer season of 2012 at Agronomy Department Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, to study the effect of irrigation and nitrogen levels on consumptive use, water use efficiency (WUE), available nutrients and uptake of nitrogen in summer sesame. Experimental results revealed that moisture studies, available nutrients like nitrogen, phosphorus and potassium and nitrogen uptake (by grain, stalk and total N uptake) were significantly higher with irrigation scheduling at 1.0 IW/CPE (Irrigation water amount/cumulative pan evaporation) and nitrogen application at 90 kg N ha -1 , over rest of the treatments. The nitrogen content in grain, stalk and total were significantly higher with irrigation scheduling at 0.4 IW/CPE which was superior over 0.6 IW/CPE, 0.8 IW/CPE and 1.0 IW/CPE and nitrogen application at 90 kg N ha -1 recorded highest nitrogen content in grain, stalk, total and WUE followed by 60 kg N ha -1 and 30 kg N ha -1 .

An experiment on integrated weed management in groundnut (Arachis hypogea) was conducted at Department of Agronomy during 2009-10. Ten treatments which included three herbicides viz., Pendimethalin, Quizolofop ethyl, Imazethapyr with mechanical weeding were studied in Randomized Block Design. Complete weed free condition recorded highest dry pod yield (1786 kgha-1). Pre-emergence application of Pendimethalin 1.0 kg a.i./ha followed by one hand weeding at 15 days after sowing, recorded 10.8 pods/plant as against 4.97 pods/plant and 60.0 nodule per plant as against 37.5 in unweeded control. Preemergence application of Pendimethalin @ 1.0 kg a.i./ha followed by post-emergence Imazethapyr @ 75 g a.i./ha at 15 days after sowing increased pod yield (1255 kgha-1), shelling % and 100 kernal weight. Application of Pendimethalin recorded increased soil fungal count 16.0X104 cfu g-1, soil actinomycetes count 15.67X106 cfu g-1 and soil bacterial count 20.33X10 cfu g-1 compared to unweeded control.

Field studies were carried out during the growing season 2015-16 at Research Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to study "Effect of different nutrient management practices and zinc fertilization on various growth and development stages of maize (Zea mays L) under dryland condition". The treatments were laid out in a randomized block design (FRBD) with three replications. The experimental results indicate that application of RDF 125% along with ZnSO 4 @ 20 kg ha -1 procured the best result in maximum growth parameters and sometime found to be at par with the application of RDF 125% along with ZnSO 4 40 kg ha -1 .
