Effect of tillage and nutrient management on wheat productivity and quality in Haryana, India

A comparison of farming practices and performance for wheat production in Haryana, India

“…Indeed the likely outcome from using zero tillage, rather than a system involving multiple cultivations, is that small yield gains are possible. This outcome is consistent with the results obtained in both shortterm studies (Coventry et al, 2011b) and long-term studies (Yadav et al, 2012(Yadav et al, , 2014. The overall reduction in inputs associated with ZT should mean that this is an appropriately economic approach to wheat cultivation (Coventry et al, 2013;Kassam et al, 2009).…”

“…This is the situation, despite ZT technology being actively taken to these areas from 2004 to 2005, plus research data showing that there is a small (up to 5%) yield improvement possible when ZT is used (Coventry et al, 2011b(Coventry et al, , 2013. This small initial uptake is partly due to lack of availability of ZT seed drills, but given the issue of heavy monsoon -crop stubble is less a problem following the pearl millet/ cluster bean crop, and the cotton sticks are removed after cotton is harvested, problems associated with the 'first-generation' ZT seeder and residue management should not be an issue.…”

“…There is widespread deficiency of Zn in different parts of Haryana and a recent survey has identified more than 50% of soils in the districts surveyed as deficient in Zn (Quinquennial Report, 2005-06). Coventry et al (2011bCoventry et al ( , 2013 showed that wheat yield is responsive to Zn application, but with the full market price of Zn and only small yield increases obtained, its application was not economic. However since 2007, the Haryana government has subsidized the use of Zn input and the extension message now given to farmers is that they apply Zn at least once per year irrespective of the rotation and district.…”

“…The rate of DAP used is most likely to assure that N is not over supplied at seeding (avoiding toxicity effects); however it may be possible that this input of P is below or at least close to the replacement levels for P in such an intensive wheat production system (Coventry et al, 2011b). The main reason of applying P in the form of DAP is that it is readily available, and other combinations, such as NPK fertilizers, are not very popular amongst farmers as they think potash is not required.…”

Residual impact of wellgrow formulation and npk on growth and yield of wheat (Triticum aestivum L.)

“…The integrated use of concentrate organic materials and inorganic fertilizers has received considerable attention in the past with a hope of meeting the farmer's economic need as well as maintaining eco-friendly conditions on long-term basis (Kumar et al 2013). Regular use of a reasonable dose of organic manure, along with crop residue recycling, is known to cater the nutrient requirements of a low to medium intensity rice-wheat cropping system (Coventry et al 2011). However, most of the long-term INM field research in South Asia pertains to rice-wheat system (Kumar and Dhar 2010).…”
