Increase in growth, productivity and nutritional status of rice (Oryza sativa L. cv. Basmati) and enrichment in soil fertility applied with an organic matrix entrapped urea

Increase in Growth, Productivity and Nutritional Status of Wheat (Triticum aestivumL.) and enrichment in Soil Microbial Population Applied with Biofertilizers Entrapped with Organic Matrix

“…No earlier study is available regarding entrapment of biofertilizers in organic matrix based on local agro-waste for production of entrapped biofertilizers. Enhanced growth and productivity of rice (Dahiya et al, 2004;Kumar et al, 2012) and Indian mustard (Sharma and Singh, 2011) by slow-release nitrogen fertilizers (SRFs) prepared by entrapment of CU in the organic matrix has been reported. In this study, a significant increase in biomass production and yield of T. aestivum has been recorded with the application of SGBF over CB (Figures 1, 2 and Tables 1-6), which indicate that efficacy of biofertilizers can be increased by such technical interventions.…”

“…Nutritional status of wheat grain which include protein, moisture, starch, wet gluten, zeleny and nutrients uptake of N, P, and K kg ha −1 in grain and straw does not differ significantly with application of SGBF, CB, and CU over NF (Tables 3 and 4). Protein content of wheat grain and other nutritional parameters were increased due to higher availability of nitrogen in soil in corns (Pearson and Jacobs, 1987), in rice (Souza, 1995;Dahiya et al, 2004;Kumar et al, 2012), in barley (Thurley and Ching, 1986) and in Indian mustard (Sharma and Singh, 2011). This shows that increase in grain protein could be due to an increase in activities of N-assimilating enzymes (Souza et al, 1995;Dahiya et al, 2004).…”

“…Azotobacter chroococcum and Bacillus subtilis are commonly supplied as charcoalbased inoculants and has been applied for wheat cultivation (Mahajan et al, 2003;Ogut et al, 2005;Broschat and Moore, 2007;Kumar et al, 2010;Ramanjaneyulu et al, 2010) Though biofertilizers offer an economically attractive and ecologically sound alternative to CU, its efficacy is significantly low in relation to the crop yield than that for the chemical fertilizer. Some studies have been conducted with the application of CRFs, SRFs, and CFs for cultivation of different crops including wheat (Dahiya et al, 2004;Mubeen 2004;Ali et al, 2005;Mubeen et al, 2006;Carlier et al, 2008;Shaharoona et al, 2008;Kandil et al, 2010;Sharma and Singh, 2011;Kumar et al, 2012). Studies have demonstrated that CU entrapped in the organic-matrixbased super granules are more effective in rice, Indian mustard and other crops (Dahiya et al, 2004;Sharma and Singh, 2011;Kumar et al, 2012).…”

No such study, however, has been reported for efficacy of such SRFs for wheat cultivation.…”

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).…”
