Present investigation was undertaken at farm of Botany , College of Agriculture, Nagpur, during rabi 2017-2018 to study the effect of two foliar sprays of 25 and 50 ppm NAA and 4%, 6%, 8% and 10% cow urine alone and in combination with one control as a water spray on morpho-physiological parameters and yield of wheat. Data revealed that treatment 10% cow urine with 25 ppm NAA significantly increa9sed plant height, number of tillers m row length, leaf area, dry weight, RGR, NAR, seed yield ha and harvest index. Considering the Benefit : Cost ratio of application 10% cow urine with 25 ppm NAA was found more economical having B:C ratio of 2.41 as compared to 1.74 in control. (
A field experiment was carried out during the kharif season of 2015-16 at Agronomy Farm, College of Agriculture, Nagpur to study the relative efficacy of herbicides on weed control in soybean.Weed control through herbicidal treatment in combination with mechanical weed control viz., Imazaethapyr + Imazamox @ 100 g a.i. ha 1 at 20 DAS + 1 hoeing at 35 DAS (T 10 ), Imazethapyr + Imazamox @75 g a.i. ha 1 at 20 DAS + 1 hoeing at 35 DAS (T 9 ) and Imazethapyr @ 75 g a.i. ha 1 at 20 DAS + 1 hoeing at 35 DAS (T 7 ), Pre-emergence Pendimethalin @ 1 kg a.i. ha 1 + 1 hoeing at 35 DAS (T 8 ) were found comparable to weed free (T 2 ) treatment in respect of reduction in weed population, weed dry matter and weed index. Weed free check treatment being at par with herbicidal treatment provided most effective control of weeds throughout the crop growth period of soybean, thereby improving growth and yield contributing characters and consequently recorded highest seed and straw yield.
Experiment was conducted on six Crossbred Heifers maintained at College dairy farm, Animal Husbandry and Dairy Science Section, College of Agriculture, Nagpur during the year 2019. Experimental heifers were fed with two different dietary levels of Hydroponic maize 40% and 60 % along with recommended concentrate mixture (Sugras), dry roughage ad libitum (Gram straw) and green maize in addition to natural grazing to determine the dry matter intake (DM) and growth performance. It was noticed that hydroponic maize is reasonably good source of energy and high source of protein in the animal. The crossbred heifers under the treatment dry roughages ad lib + 100% green maize fodder showed significantly (P<0.05) higher (4.57 kg day -I heifers -I ) DM intake day -I as compared to the treatment dry roughages ad lib (Gram straw) + 60% green maize + 40% hydroponic maize (3.84 kg day -I heifer -I )) and the another treatment dry roughages ad lib (Gram straw) + 40 % green maize + 60% hydroponic maize (3.36 kgday -I heifers -I ). Decreased trend in DM intake was observed with increased level of hydroponic fodder in the ration of experimental heifers. Daily dry matter intake increased (4.57 kgday -I ) significantly (P<0.05) in heifers under the treatment T 1 :Dry roughages ad lib (Gram straw) + 100% green maize fodder under the treatment. Higher weekly and daily gain in body weight (5.14 and 0.73 kg) of experimental heifers increased significantly under the treatment T 3 (dry roughages ad lib (Gram straw) + 40 % green maize + 60% hydroponic maize). The 1 and 5.42),T 2 :dry roughages ad lib+60% Green maize +40% Hydroponic maize (9.11,7.61and 6.13) and T 3 :dry roughages ad lib +40% Green maize+60% Hydroponic maize (10.36,7.68 and 7.03).The differences in gain in body measurement of experimental heifers found to be significant (p <0.05).
