A field experiment was conducted during 2010-11 and 2011-12 at Jabalpur, Madhya Pradesh to study the impact studies of different resource conservation practices on rice and wheat equivalents, total productivity, production efficiency, water use efficiency and economics of 4 cropping systems viz. CS1, rice (Oryza sativa L.) - wheat (Triticum aestivium L.), CS2 rice - berseem (Trifolium alexardrinum L.), CS3 maize (Zea mays L.)-wheat and CS4 sorghum (Sorghum bicolor L.)-wheat. The rice - berseem cropping system recorded the highest total productivity in terms of rice equivalent yield (t/ha/year) and found 29.31%, 29.02% and 8.58% higher than the maize - wheat, sorghum - wheat and rice - wheat cropping systems, respectively as well as the production efficiency of former cropping system was 29.64,20.63 and 10.69 percent higher over maize - wheat, sorghum - wheat and rice - wheat cropping systems. Rice and wheat equivalents were higher by 3.6 and 2.8 percent under conventional tillage over minimum tillage. Though the total productivity and production efficiency were lower under recommended dose of fertilizer (RDF) than the RDF+25% N through organic source but net returns and benefit: cost ratio was higher. © EM International ISSN 0971-765X.

The study was conducted to evaluate the various parameters of ground water which are being used as irrigation water in the field. The assessment was carried out in different villages of Sheopur tehsil of Sheopur district in Chambal Command area of Madhya Pradesh during 2007-08. Under the study, 121 ground water samples from the different sources (wells/tube-wells) have been collected. The samples were subsequently analyzed chemically for the various parameters and the data are being presented, which are the prime causing factors in creating further, the various water related problems. The presented data were furnished based on the criteria suggested by Richards (1954) and Minhas et al. (1998). Most of the water samples (108) were found to be in the good range of water categoiy and were suitable for irrigation with the optimum management practices.

Field experiment was carried out during rabi seasons of 2004-05 and 2005-06 at National Research Centre for Weed Science (NRCWS), Jabalpur, Madhya Pradesh to evaluate different tillage systems on growth, yield and economics of mustard varieties and soil properties. The mustard varieties grown under zero tillage (16.60 q/ha) gave higher seed yield than conventional tillage (14.09 q/ha). Among the cultivars, maximum mean seed yield was produced by Varuna (17.63 q/ha). Zero tillage sowing of mustard gave maximum net monetary returns and benefit : cost ratio (Rs. 56354 and 3.4) than conventional till sown mustard (Rs. 51336 and 2.5). Varuna variety gave maximum net returns and B : C ratio than others.

A long term experiment was conducted on integrated nutrient management in rice-wheat system at Jabalpur (M. P.) since kharif season 1987-88 to evaluate the sustainable productivity of rice on long term basis. The present paper deals with the studies during the years 2002-03 and 2003-04. Integrated use of 50% N through FYM/ wheat staw/green leaf manuring with sunnhemp+50% NPK to rice followed by 100% NPK to wheat or 25% N through FYM/wheat straw/green manuring with sunnhemp+75% NPK to rice followed by 75% NPK to wheat was comparable to application of 100% NPK to both the crops in terms of different growth parameters, yield attributes, productivity, nutrient uptake and economics of rice.
