Hailstorms can be responsible for significant economic loss to the agricultural sector in Alberta, Canada. Foliar applications of certain fungicides and nutrient blends have been advocated promote recovery yield hail-damaged crops. Proper understanding different crop hail-related factors is required an accurate assessment hail damage crops evaluations hail-recovery product claims. This study wa...

abstract plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. a factorial experiment was conducted in greenhouse to determine the efficacy of four strains of fluorescent pseudomonas on wheat yield and yield component under saline conditions. the experiment was carried out with the following treatments (non –inoculation control and inoculation with p.f...

limitations of water and nitrogen in soil usually restrict plant growth. the objective of this study was to evaluate the effects of different amounts of supplemental irrigation at different growth stages and application of different rates of nitrogen fertilizer on grain yield and water productivity of wheat cultivars. a field experiment was conducted in the agricultural research station of shah...

in order to examination of dual purpose herbicides on some wheat physiological indexes in different stages of phenology of this corp, an experiment was conducted in 1386-1387, in kordkoy, golestan province with dry farming condition. this study was performed as factorial in randomized complete block design with 2 factors and 4 replications. the first factor included the type of herbicides: shov...

Fraction of Photosynthetically Active Radiation (FPAR) is a critical parameter in land surface energy balance and climate modeling. Several global FPAR products are available, but these still require considerable assessment and validation due to low spatial resolution. Three major FPAR products that have covered China and provided continuous time series data—MODIS, MERIS and GEOV1—were assessed...

Understanding the time-course of dry matter (DM) and nitrogen (N) accumulation in terms of yield-trait relationships is essential to simultaneously increase grain yield and synchronize N demand and N supply. We collected 413 data points from 11 field experiments to address patterns of DM and N accumulation with time in relation to grain yield and management of winter wheat in China. Detailed gr...

Jiangsu is an important agricultural province in China. Winter wheat, as the second major grain crop in the province, is greatly affected by moisture variations. The objective of this study was to investigate whether there were significant trends in changes in the moisture conditions during wheat growing seasons over the past decades and how the wheat yields responded to different moisture leve...
