Based this, main economic parameters agrotechnologies cultivation were calculated. Short-term field was carried out in period 2020-2022 lands Brylivske Institute Water Problems Reclamation National Academy Agrarian Sciences (Khe...

The main effects of three different irrigation regimes, i.e., sustained deficit irrigation (SDI), regulated deficit irrigation (RDI) and non-irrigated (NI), on seed traits namely proanthocyanidins (PAs) were evaluated in the wine grape cultivar Aragonez (syn. Tempranillo) grown in Alentejo (Portugal) over two growing seasons. Results showed that while the number of seeds per berry was not affec...

Wang Shengfeng,Xu Jianxin,Yang Shuqin,Jia ping (North China University of Water Resources and Electric Power, Zhenzhou, P. R. China) Email:[email protected] Abstract:Winter wheat and summer maize were important grain crops in China,and winter wheat-summer maize continuous cropping was the main tillage method in north China.According to field experiment datas, Jensen models of winter wheat and...

Summer maize crop development, yield, and water use characteristics under deficit conditions at different growth stages were investigated in this study using irrigation regime treatments the seedling (S), jointing (J), tasseling (T), grain filling (F) 2018 2019 China. Ten set, including three-irrigation application intervals (JTFi, STFi, SJFi, SJTi), two-irrigation applications (STi, JTi, JFi),...

The effects of conservation-tillage practices on the root environment of corn (Zea mays L.) may differ with varying amounts of irrigation. Dryland, 50% irrigation, and 100% irrigation treatments were applied in combination with disc, no-tillage, and a postemergence chisel treatment designed to allow rapid infiltration of irrigation water. The study was conducted during the 1980 growing season a...

The article presents the results of studies various sesame varieties on irrigation regime and their seed production, as well selection a variety that meets requirements regional conditions. Plant productivity indicators mainly depend length plant stem, regime, grain size number grains per plant. highest yield was obtained from Tashkent-122 variety, where height plant, weight 1000 grains, pods a...

A field experiment was conducted during the years 2019-20, 2020-21 and 2021-22 suru seasons with eight sugarcane cultivars two irrigation regimes were evaluated in strip plot design three replications. The impact of water stress on various morphological characters such as plant height, leaf area, area index tiller count recorded at 0.3 1.0 IW/CPE regime. Drought treatment caused an average redu...
