Ensuring yield sustainability and nutritional security through enriching manures with fertilizers under rice–wheat system in North-western India

Effect of addition of organic manures on basmati yield, nutrient content and soil fertility status in north-western India

“…Thus, it eventually increased the grain-size and thus 1000 grain weight. The present results are in line with the results obtained in literature [ 21 ], where addition of manures along with inorganic fertilizers increased the plant growth parameters. Thus, the present results demonstrated that for optimum growth of plant, 100% N can be replaced with some portion of manures.…”

“…The application of organic manures showed a positive impact on plant height and panicle length, however significant increase in case of poultry manure+75% N was observed over the control. The results for plant height might be due to the presence of high N content in manures, particularly in poultry manure, which favoured the vegetative growth of basmati [ 21 ]. The highest panicle length of basmati with application of poultry manure+75% N was possibly associated with the higher P content in poultry manure, whereas untreated plants showed least panicle length as compared to the treated ones.…”

“…Previous studies have reported that substitution of chemical fertilizers with organic manure have beneficial effects on crop yield [ 19 , 20 ]. Use of different manures (press mud, poultry manure and farmyard manure) in rice-wheat system has evidenced to increase the crop yield and DTPA-extractable micronutrients (Zn, Cu, Fe and Mn) concentrations in soil of north-western India [ 21 , 22 ]. In long-term field experiment of 40 years under soybean-maize rotation, the application of organic manures on brown soil improved the crop yields along with soil properties [ 23 ].…”

“…Another study reported the beneficial effect of maize residue incorporation on the seed yield of soybean [ 25 ]. Under the rice-wheat cropping system, the retention of crop residue has increased the micronutrient content in the crop [ 21 ].…”

Multifaceted Ability of Organic Fertilizers to Improve Crop Productivity and Abiotic Stress Tolerance: Review and Perspectives

“…The application of poultry and farmyard manure improves the crop productivity and soil nutrient (Zn, Cu, Fe and Mn) concentration [69][70][71]. In another 40-year long-term study, the application of organic fertilizers considerably increased the maize and soybean yield and soil productivity [72].…”
