Considering the current upward drift in farm use all over the world, the Russian agro-food market has immense possibilities to create such economic conditions under which the farming sector could develop dynamically. The increase in the grain production is of crucial importance for all agricultural branches. In this respect, the grain sector is Russia’s strategically significant economic segmen...

We present continuum models to describe colloid release in the subsurface during transient physicochemical conditions. Our modeling approach relates the amount of colloid release to changes in the fraction of the solid surface area that contributes to retention. Equilibrium, kinetic, equilibrium and kinetic, and two-site kinetic models were developed to describe various rates of colloid release...

Genotypic variations in leaf gas exchange and yield were analysed in five upland-adapted and three lowland rice cultivars subjected to a differential soil moisture gradient, varying from well-watered to severely water-stressed conditions. A reduction in the amount of water applied resulted in a significant decrease in leaf gas exchange and, subsequently, in above-ground dry mass and grain yield...

Whole!plant responses to elevated CO1 throughout the life cycle are needed to understand future impacts of elevated atmospheric CO1[ In this study\ Triticum aes! tivum L[ leaf carbon exchange rates "CER# and carbo! hydrates\ growth\ and development were examined at the tillering\ booting\ and grain!_lling stages in growth chambers with CO1 concentrations of 249 "ambient# or 699 "high# mmol mol[...

Plastic film mulching (PM) is widely utilized for maize production in China. However, the effect of PM on the grain yield of crops has not been established, and the biochemical mechanism underlying the increase or decrease in grain yield under PM is not yet understood. Grain filling markedly affects the grain yield. The objective of this study was to investigate the effects of PM on maize grain...
