concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...

in order reaching to occurate water regime under minimum tillage system and its effect on the physiological indices of 3 rice cultivars an experiment  was conducted as a split-plot design based on  randomized complete block with three replication in the year of 2006-2007 at research field of shavour station. treatment contains three water regimes with one day or check, two (i2) and three days (...

The sprinkler irrigation system is the most widely used for rubber in a nursery. However, method associated with high water loss during irrigation. In view of this, an experiment was conducted to assess effect different systems on growth dynamics, leaf ratio analyses, productivity, and use efficiency seedlings. treatments were systems; soil + overhead (CON), growing media (GM) drip (DRP), GM ca...

Oilseed crops grown in different types of soil experience nutrient deficiency, especially sulphur, zinc and boron, which affect crop productivity. To tackle it, management practices must be streamlined to avoid improper fertilizations deterioration health. With this background, experimental trials were conducted study the effect boron application on growth, yield components hybrid sunflower at ...

The field experiment was carried out at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj during Rabi season 2021-22 on Mustard crop. performed in randomized block design with ten treatments three replication. soil experimental plot sandy loam texture, nearly neutral reaction (pH 7.1), low organic carbon (0.36%), availabl...
