Water stress is a frequent and critical limit to wheat (Triticum aestivum L.) production in North China. It has been shown that photosynthetic active radiation (PAR) is closely related to crop production. An experiment was conducted to investigate the effects of deficit irrigation and winter wheat varieties on the PAR capture ration, PAR utilization and grain yield. Field experiments involved J...

With reduced water resources available for agriculture, scientists and engineers have developed innovative technologies and management strategies aimed at increasing efficient use of irrigation water. The objective of this research was to study the impact of deficit irrigation strategies on sorghum grain attributes and bioethanol production. Grain sorghumwas planted at Southwest Research-Extens...

The aim of this study was to evaluate the response corn (Zea mays L.) grain yield nitrogen (N) fertilizer application and its residual effect on soybean (Glycine max (L.) Merr.) seed yield. During 2020 growing season, a corn-soybean rotation continued at Scandia, KS (USA), evaluating five N rates in under both dryland irrigated conditions. Average yields ranged from 110 206 bu/a for dryland, 19...

The Inland Pacific Northwest (IPNW) encompasses 1. 6 million cropland hectares and is a major wheat-producing area in the western United States. The climate throughout the region is semi-arid, making the availability of water a significant challenge for IPNW agriculture. Much attention has been given to uncovering the effects of water stress on the physiology of wheat and the dynamics of its so...

This work determined the impact of irrigation on the seasonal dynamics of populations of Pseudomonas spp. producing the antibiotics phenazine-1-carboxylic acid (Phz(+)) and 2,4-diacetylphloroglucinol (Phl(+)) in the rhizosphere of wheat grown in the low-precipitation zone (150 to 300 mm annually) of the Columbia Plateau of the Inland Pacific Northwest. Population sizes and plant colonization fr...

In order to study the effect of zeolite and biologic fertilizers application under different irrigation regime on yield and quantitative traits in sugar beet, a research project was conducted according split-split plot experiment based on randomized complete block design with four replicates. The main factor included irrigation regime at two levels (Normal and stress), sub factor included zeoli...

The aim of this study was to evaluate the response corn (Zea mays L.) grain yield nitrogen (N) fertilizer application and its residual effect on soybean [Glycine max (L.) Merr.] seed yield. During 2021 growing season, a corn-soybean rotation continued at Scandia, KS (USA), evaluating five N rates (0, 53, 107, 161, 214 lb N/a) applied in under both dryland irrigated conditions. Average yields ra...
