Agro-meteorological index insurance is an innovative agricultural insurance product that has solved problems of conventional agricultural insurances including excessive cost and moral hazard. Agro-meteorological index insurance has become an effective agricultural insurance scheme. This paper primarily uses meteorological data and winter wheat yield data in the Jiangsu Province for the last 35 ...
The effects of salinity stress on grain quality traits of wheat were investigated using 180 lines of F5 generation in two environments (normal and salinity stress). A randomized complete block designs with three replications was used in each of the environments at the Research Farm of the Agricultural and Natural Resources Research Station of Isfahan in 2019-2020 cropping season. Grain yield, p...
Simulation of water and nutrient processes can enhance intensive agriculture to help feed the world’s population in a sustainable manner. Due to excessive N application, environmental protection and agricultural sustainability have become major issues in agriculture. In this study, we calibrated and tested the RZWQM model to assess N management in a double-cropping system comprised of winter wh...
Extended Abstract Introduction and Objective: Due to the lack of micronutrient elements and the urgent need for biofortification in important and strategic plants in the nutrition of human society such as wheat, it is necessary to evaluate any strategy to optimize the quality and production of this product. This has led researchers to investigate the effect of foliar application of zinc and ir...
The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...
One way to increase crop yield per unit of area is to close the gap between actual and potential yield in cropping systems. This study was conducted to determine the factors that affeced wheat yield gap in Khorramshahr, Iran during 2018-2019 growing season. In this study 60 fields of different areas under cultivation, field management practices and grain yield yield levels were surveyed based o...
the chemical inputs threat the health of water, soil and organisms. thus, it is essential to encourage farmers to produce products with minimum use of chemical inputs. using the ordered logit model and a cross sectional data of 186 producers in 2012, this study attempted at investigating influential factors on willingness to accept (wta) of khorasan razavi province farmers to produce greenhouse...
