(Enviro Media, 2015) Santosh Kumar; J.S. Bohra; Rakesh Kumar; Gargi Goswami; Narendra Kumawat
A field experiment was conducted during 2011 and 2012 at Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh to evaluate effect of cropping sequences on productivity, energetic and economics on rice-based cropping system. Rice-potato-green gram crop sequence recorded the highest system productivity (52.0 kg ha-1 day1) fallowed by rice-vegetable pea-lady's finger and rice-maize (cob) + vegetable pea (1:2)-cowpea fodder crop sequences. However, the highest energy use efficiency was recorded in rice-maize (green cob) + vegetable pea (1:2)-cowpea fodder (2.98) closely followed by rice wheat (2.80) sequence. Rice-green gram and rice-maize (cob) + vegetable pea (1:2)-cowpea fodder produced 185.7 MJ haa and 169.9 MJ ha1 gross output energy, respectively. With substitution of wheat by mustard in rabi and intensification in summer season with green gram recorded the highest energy productivity (258.6 g MJ-1). Gross return (Rs. 259159), net return (Rs. 150227), B: C ratio (2.38) as well as system profitability (Rs. 412 ha-1 day-1) was recorded maximum in rice-potato-green gram crop sequence followed by rice-vegetable pea-lady's finger crop sequence. © Copyright EM International.
Effect of weed management practices under various fertility levels on yield, nitrogen content and protein of spring mungbean
(Enviro Media, 2014) Gargi Goswami; Chandra Bhushan; Anil Shukla; Santosh Kumar
A field experiment was conducted during spring season of 2012-13. The experiment consisted of four treatments of fertility levels in main plot (RDF, % RDF +2% urea spray, two sprays of 2% urea and control) and five treatments of weed management in subplot (pendimethalin @ lkg/ha, imazethapyr @ 50 g/ha, chlorimuron-ethyl @ 4 g/ha, hand weeding and weedy check), thereby making twenty treatment combinations tested in split plot design with three replications. Results indicated that application of RDF significantly increased the number of pods, seed yield and biological yield over other fertility levels. Results further indicated that among weed management practices hand weeding resulted in increase in the number of pods, seed yield and biological yield which was followed by application of pendimethalin. The fertility levels significantly influenced the N content in straw and grains while the affect of the weed management practices was significant on N content in grains, only. However both the management practices influenced the protein content in grains significantly. Copyright © EM International.
Yield, nutrient content and nutrient uptake of rice as influenced by rice based cropping system in Varanasi of Eastern Uttar Pradesh, India
(2014) Santosh Kumar; J.S. Bohra; Kiran Rana; Gargi Goswami; P.K. Mishra
Continuous adoption of cereal-cereal cropping system has led to deterioration of soil quality resulting in a serious threat to its sustainability and food security in hot sub-humid region of eastern Varanasi, India. Therefore crop diversification with wider choice in the production of a variety of crops is being promoted meet the demand of balanced food for increasing population. Ten rice- based crop sequences were tested to found the influence of different crop sequences on yield, nutrient content and uptake of nutrient by rice. Rice in rice-wheat-sesbania crop sequence recorded highest number of effective tiller (414.6 nr-2) than other crop sequences whereas, number of non effective tiller (m 2) of rice was found maximum (53.33 m-2) in rice-wheat-green gram sequence followed by rice-wheat sequence (52.33 m2). Grain filling % of rice was recorded maximum in sequence (58.9) but test weight (g) of rice was found maximum (28.17) in rice-mustard-green gram sequence. Grain and straw yield (q ha-1) of rice was reported highest in rice-wheat-sesbania and rice-potato green gram sequence respectively. However, highest harvest index (35.62) was reported in crop sequence. N, P, and K content of rice grain was found highest in rice-maize (green cob)+ veg. pea (1:2)-cow pea(f), rice-wheat+mustard (5:l)-black gram and rice-veg. pea-lady's finger sequence respectively. Rice-wheat-sesbania crop sequence recorded highest N and P uptake (i.e. 89.1 and 20.07 kg ha1, respectively) of rice among all the sequences. Copyright © EM International.
