Irrigation and nitrogen (N) are two crucial factors affecting perennial grass seed production. To investigate the effects of irrigation N rate on yield (SY), components, water use efficiency (WUE) Cleistogenes songorica (Roshevitz) Ohwi, an ecologically significant grass, a four-year (2016–2019) field trial was conducted in arid region northwestern China. Two regimes (I1 treatment: at tillering...

Efficient nitrogen (N) nutrition has the potential to alleviate drought stress in crops by maintaining metabolic activities even at low tissue water potential. This study was aimed to understand the potential of N to minimize the effects of drought stress applied/occur during tillering (Feekes stage 2) and jointing (Feekes stage 6) growth stages of wheat by observing the regulations and limitat...

Sustainability of rice production under limited water conditions is threatened by increasing irrigation water scarcity. Therefore, physiological and morphological responses of rice to varying water stress management strategies should be determined. The physiological and morphological responses of a semi dwarf rice (Hashemi cultivar) to water stress intensities (mild and severe, i.e., short-dura...

The ideotype approach has been used in breeding programs at the International Rice Research Institute (IRRI) and in China to improve rice yield potential. First-generation new plant type (NPT) lines developed from tropical japonica at IRRI did not yield well because of limited biomass production and poor grain filling. Progress has been made in second-generation NPT lines developed by crossing ...

Rising concentration of surface O3 threatens crop production and food security. To improve the evaluation develop efficient adaptations, it is essential to study effects acute pollution. We adopted this by open-top chamber (OTC) method found that fumigation elevated (NF40) for short (tillering jointing, heading ripening) long periods during rice growth reduced grain yield 17, 19 25%, respective...

Pearl millet is the most widely grown cereal crop in arid and semi-arid regions of Africa, Niger particular. To determine an optimized management strategy for smallholder farmers southern to cope with production failure improve cropping performance context climate change variability, multi-site trials were conducted evaluate impacts transplanting on pearl growth productivity. Eight treatments v...

Dry direct seeding cultivation technology of rice is an important aspect production and management. Six treatments were designed in this paper, that is, T1 (conventional irrigation), T2 irrigation + conditioner), T3 (30% water-saving T4 T5 (50% T6 conditioner). The results showed the three separate treatments, 30% was conducive to growth dry at tillering stage, jointing booting 50% more grain f...
