Integrated Nutrient Management for Sustainable Production of Rice-Wheat Cropping System in Sodic Soils

To keep the pace of sustainable crop production without depleting the natural resource base seems to be a big challenge under the current scenario. Nutrient cycling in the soil-plant ecosystem is an essential component for sustaining the agricultural enterprises productions. Integrated nutrient management i.e. combined use of organic and inorganic fertilizer sources, is quite helpful in sustaining the system productivity and soil quality. The INM concept is now being broadened to make it more context-specific for the local environmental conditions, farm mechanization, conservation agriculture, shift towards organic agriculture, and the updated soil maps. An innovative approach like INM can harness natural resources appropriately, bring about food security, and improve the livelihood. The provision of appropriate policies, for e.g. providing incentives to adopt INM, and easy and quality availability of organic inputs will motivate the farmers to adopt INM practically.Directorate of Extension, Ministry of Agriculture and Farmers’ Welfare, Government of Indi

Not AvailableThe present study was undertaken to study the influence of sowing methods and mulching on soil salt dynamics and performance of fodder sorghum. Results showed that the application of saline water (4 irrigations with 6.0 dS/m EC), gradually increased the soil salinity in soil profile depth of 0-60 cm. The mean soil salinity in 0-60 cm soil increased by 127.2 per cent over normal irrigation water. Among the sowing methods, ridge and furrow sowing with alternate furrow irrigation recorded lowest salinity development in upper soil layers. The salinity was 36.4 and 49.1 per cent higher under two row raise beds as compared to ridge and furrow in upper 0-15 and 15-30 cm soil layers, respectively. Mulching with crop residue maintained lower levels of salinity over bare soil. Mulched soil had 24.8 per cent higher moisture content in 0-60 cm soil profile then un-mulched treatment. Irrigation with saline water significantly reduced the fodder yield of sorghum by 10.6 per cent as compared to irrigation with normal water. Sowing of fodder sorghum on two row raised beds recorded significantly highest fodder yield over flat bed and ridge and furrow sowing which was 8.2 per cent higher over flat bed sowing.Not Availabl

Not AvailableSalinity hinders the crop growth right from germination to maturity of crop plants by altering the water relations, nutrient balance, specific ion toxicity etc. Agronomic practices, though cannot reclaimed or remove the salts from the soil, but have potential role in managing the salt and water balance in the crop root zone and apart escaping and tolerance mechanism to the crop plants grown. Adoption of package of best agro-techniques like selection of appropriate crop and its varieties, priming of seed prior to sowing, sowing with appropriate methods, irrigation with minimized salt load in soil, balanced fertilization etc. can sustain the yield of salty soils.Directorate of Extension, Ministry of Agriculture and Farmers’ Welfare, Government of Indi

Not AvailableThe abiotic stresses, such as soil salinity and sodicity are largely responsible for the low productivity of horticultural crops mainly due to low availability of micro-nutrients especially as zinc (Zn) and iron (Fe). Therefore, judicious management of plant nutrients in these soils is as important as their reclamation.Not Availabl

Not AvailableThe antagonistic potential of bacteria is being applied to biocontrol the infectious diseases caused by pathogenic fungi in plants that are one of the major threats to the growth and productivity of crop plants. In the present study, bacterial strains were isolated from soil samples collected from the rhizosphere of Sorghum (Sorghum bicolor) and Wheat (Triticum aestivum). Microscopic analysis revealed that all three bacterial isolates were Gram-positive, rod-shaped and spore-forming. The isolates Bacillus subtilis BP171 and Bacillus amyloliquefaciens BP124 demonstrated salt tolerance up to 12% while Bacillus subtilis BP67 tolerated up to 10% of NaCl. All the three strains were screened against seven test pathogenic fungi like Bipolaris sorokiniana, Fusarium oxysporum, Aspergillus sp., Penicillium sp., Rhizoctonia solani, Aspergillus niger, and Fusarium sp. for their antagonistic activity. BP124 was found to be the most potent in comparison to BP67 and BP171. Bacillus amyloliquefaciens BP124 demonstrated significantly highest (p<.0001) inhibition percentage against Fusarium sp., (61%) and Fusarium oxysporum (60%). The optimization of various parameters like pH, temperature, inoculum size, agitation, carbon sources, and nitrogen sources was carried out to enhance the antagonistic potential of bacterial isolates. The results revealed that the bacterial isolates were able to demonstrate significantly highest (p<.0001) antagonistic potential when inoculum size required for the growth was 1ml, agitation rate at 150 rpm, while the medium of pH at 7.0 and 30oC incubation temperature. Starch as carbon source and peptone as nitrogen source supported significantly highest (p<.0001) antagonistic activity against all the fungal pathogens for all the bacterial isolates. Therefore, the study showed that appropriate and optimum fermentation conditions can be of great importance in enhancing the antagonistic potential of bacterial isolates
