Performance of poplar (populus deltoides bartr.) and its effect on wheat yield under agroforestry system in irrigated agro-ecosystem, India
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
متن کاملEvaluation of Various Integrated Rodent Management Modules in Irrigated Rice Ecosystem
Rodents are one of the major biological production constraints of paddy. Field experiments were carried out to evaluate the efficacy of seven different integrated rodent management modules against rodent pests in irrigated rice ecosystem during kharif and rabi seasons of 2011-12. The modules efficacy was assessed by live burrow count and diagonal methods simultaneously before and after impositi...
متن کاملSurvey of nitrogen use pattern in rice in the irrigated rice-wheat cropping system of Haryana, India.
Seeing the sustainability of rice-wheat cropping system (RWCS) of the Indo-Gangetic Plain, adequate crop nutrition in general and nitrogen (N) in particular holds the key to sound crop management. The excessive application or insufficient management of N means an economic loss to the farmer and may lead to yield penalties and environmental problems. Improving N management in consonance with oth...
متن کاملResidual phosphorus and zinc influence wheat productivity under rice-wheat cropping system.
Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop productivity. One strategy to increase crop productivity under rice-wheat system is balanced application of crop nutrients. Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha(-1)) and zinc (0, 5, 10, 15 kg Zn ha(-1)) on the productivity of rice ge...
متن کاملClimate change impacts on irrigated rice and wheat production in Gomti River basin of India: a case study
Potential future impacts of climate change on irrigated rice and wheat production and their evapotranspiration and irrigation requirements in the Gomti River basin were assessed by integrating a widely used hydrological model "Soil and Water Assessment Tool (SWAT)" and climate change scenario generated from MIROC (HiRes) global climate model. SWAT model was calibrated and validated using monthl...
