A regional regression model was developed to estimate the spatial distribution of ground water recharge in subhumid regions. The regional regression recharge (RRR) model was based on a regression of basin-wide estimates of recharge from surface water drainage basins, precipitation, growing degree days (GDD), and average basin specific yield (SY). Decadal average recharge, precipitation, and GDD...

A new maize (Zea mays L.) simulation model, Hybrid-Maize, was developed by combining the strengths of two modeling approaches: the growth and development functions in maize-specific models represented by CERES-Maize, and the mechanistic formulation of photosynthesis and respiration in generic crop models such as INTERCOM and WOFOST. It features temperature-driven maize phenological development,...

The Balkan peninsula is a transitional zone, in terms of bioclimatic conditions, with an extended and dynamic agricultural sector. Its potential peril due to climate change socioeconomic factors. To assess evaluate the agrometeorological conditions related trends which affect widely cultivated wheat maize, big dataset high spatiotemporal analysis was utilized. thermal indices Growing Degree Day...

introduction lentil with about 28 percent protein occupies the second after soybean. it is one of the major crops in developing countries as a complement to cereals and is an excellent source of protein and amino acids in the diet. results of studies shown that for most crops, including lentil, the occurrence of drought stress in some phenology stages cause irreparable damages to yield. therefo...

Abstract Yellow nutsedge is one of the most widely distributed and troublesome weeds in world. Field greenhouse studies were conducted to optimize strategies for increased yellow control turfgrass with halosulfuron sulfentrazone. In field study perennial ryegrass mixture, single or sequential applications (3 wk after initial) sulfentrazone made on June 3, 23, July 15, August 5 2013, 2014, 2015,...

Alpine ecosystems are seriously threatened by climate change. One of the key mechanisms by which plants can adapt to changing environmental conditions is through evolutionary change. However, we still know little about the evolutionary potential in wild populations of long-lived alpine plants. Here, we investigated heritabilities of phenological traits, leaf size, and performance traits in natu...

Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize production. The objective this research was to generate information on the production six hybrids their progenitors, adapted tropical lowlands. Data days to—and duration of—flowering, distance spike stigmas, five female single crosses male inbred lines were recorded for ...
