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.
A field experiment were conducted during kharif season of 2016 to 2018 to study the response of soil and foliar application of zinc and iron for increasing the growth and yield of sesame at Oilseeds Research Station, MPKV, Jalgaon (MS). The soil of experimental field was vertisoles low in nitrogen (221 kg ha -1 ) medium in phosphorus (21.60 kg ha -1 ), rich in potassium (675 kg ha -1 ), low in zinc (0.5 ppm) and iron (4.3 ppm) with alkaline in reaction (pH 8.20). The experiment was laid out in randomized block design with eleven treatments and three replications viz. T1 -Control (RDF + FYM), T2-T1 + Soil application of ZnSO4 @ 25 kg ha -1 , T3 -T1 + Foliar application of ZnSO4 @ 0.5 % at 30 & 45 DAS, T4 -T1 + T2 + T3, T5 -T1 + Soil application of FeSO4 @ 25 kg ha -1 , T6-T1
A field experiment was conducted during kharif season of 2010-2015 for five years at Oilseeds Research Station, Jalgaon, to find out the suitable planting pattern and land configuration in groundnut + sesame intercropping system. The experiment was conducted on clay textured soil low in available nitrogen (196 kg ha -1 ), medium in phosphorus (17.6 kg ha -1 ) and high in potash (604 kg ha -1 ) with slightly alkaline in reaction having pH 8.20. The experiment conducted in randomized block design having fourteen treatment combinations replicated thrice. The treatment consists of sole groundnut and sesame at recommended spacing, sole crops with skip row in 2:1, 3:1 and 4:1 row proportions, intercropping of groundnut + sesame in 2:1, 3:1 and 4:1 row proportions and intercropping of groundnut + sesame in 2:1, 3:1 and 4:1 row proportions with skip row after each intercrop combination. The openings of furrow in every skip row were done after 30 days after sowing. Among different intercropping of groundnut + sesame in 4:1 row proportions gave significantly higher groundnut equivalent yield (1986 kg ha -1 ), land equivalent ratio (1.30), net returns (Rs.54768 ha -1 ) and B: C ratio 2.54 followed by groundnut + sesame in 3:1 row proportion recorded groundnut equivalent yield (1950 kg ha -1 ), land equivalent ratio (1.28), net returns (Rs.53560 ha -1 ) and B: C ratio 2.52. Also the moisture conservation technique of furrow opening shows significant results in intercropping combinations as well as in sole cropping of groundnut and Sesame.
