dc.description.abstract | A field experiment was conducted from kharif 2020 to rabi 2021-2022 at the Irrigation and Water Management Farm of Department of Soil Science, CSKHPKV, Palampur. (H.P.) to study the effect of seed priming, nutrient management and tillage practices on productivity of rainfed maize-wheat cropping system. The experiment was laid out in randomized block design with three factors viz., tillage practices, seed priming and nutrient management practices and was replicated thrice. The treatments comprised of three tillage practices [Conventional tillage (CT), CT + mulch (CT+M) and Zero tillage+ mulch (ZT+M)]; two seed priming [Hydropriming and micronutrient priming (0.5%Zn and 0.1%Mn)] and two nutrient management practices [recommended dose of fertilizers (RDF) (120:60:40 in maize and 80:40:40 in wheat) and Integrated nutrient management(50% N through FYM + 50% N and rest of P and K through inorganic sources)]. An additional treatment of control (CT, No priming, RDF) was also kept for general comparison of results. The soil of the experimental site was silty clay loam in texture, acidic in reaction, medium in organic carbon, available phosphorus and potassium and low in available nitrogen. Results revealed that significantly higher growth and yield attributes, yield, nutrient content and uptake, system and water productivity and economic returns were obtained with conventional tillage + mulch followed by zero tillage + mulch amongst tillage practices, integrated nutrient management over RDF among nutrient management, whereas seed priming methods did not differ with respect to different parameters. As compared to initial status soil physical and chemical properties viz. bulk density, porosity, hydraulic conductivity, organic carbon, available nitrogen, phosphorus and potassium content at end of two years cropping cycle improved significantly under conventional tillage + mulch and integrated nutrient management practice followed by zero tillage + mulch and integrated nutrient management system. For obtaining higher crop and water productivity as well as economic returns in maize-wheat cropping system under rainfed condition, conventional tillage + mulch practice with integrated nutrient management and seed priming should be adopted. | en_US |
