Forage production is primarily limited by weather conditions under dryland production systems in Brazilian semi-arid regions, therefore sowing at the appropriate time is critical. The objectives of this study were to evaluate the CSM-CERES-Pearl Millet model from the DSSAT software suite for its ability to simulate growth, development, and forage accumulation of pearl millet [Pennisetum glaucum...

Analyses of covariance were used to relate corn yields to population densities of Pratylenchus hexincisus in South Dakota dryland corn or P. scribneri in irrigated corn. The relationship for P. hexincisus was Y = 5,825 - 0.14X - 0.03X' where Y = yield (kg/ha), X = number of P. hexincisus per gram of dry root at midseason and X' = number at harvest. The relationship for P. scribneri was best des...

Drought has been a major cause of agricultural disaster, yet how it affects the vulnerability of maize and wheat production in combination with several co-varying factors (i.e., phenological phases, agro-climatic regions, soil texture) remains unclear. Using a data synthesis approach, this study aims to better characterize the effects of those co-varying factors with drought and to provide crit...

Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...

Good quality and economical availability of fodder could be a substitute for crop production in the farming system dryland areas. In Pakistan, increasing demands crops animal feed require immediate attention to find viable options production. Additionally, climate change, land detritions, imbalanced use chemicals led an agro-ecological imbalance which needs focus on mitigation strategies practi...

Shifts in rainfall frequency and intensity can lead to heavy crop loss rainfed agricultural systems. Small-scale farmers who plant with limited resources need carefully select management strategies that are well suited for their environment. Farmers must choose between planting higher-yielding varieties take longer mature lower-yielding be harvested sooner. To better understand the interactions...

The aim of this study was to clarify the distribution irrigated drylands in arid and semi-arid areas, where complex terrain, diverse crops staggered cultivated lands exist. This paper studied classification methods based on temperature, precipitation, Normalized Difference Vegetation Index (NDVI) Water (NDWI) from Landsat data one-harvest area northern Loess Plateau China by using Google Earth ...

Water deficit is an important factor limiting crop growth all over the world. In order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. The experiments were carried out at the Agricu...

the west asia-north africa region, which is characterized by a typical mediterranean climate, is the center of origin of cereals, notably wheat (triticum spp.) and barley (hordeum spp). however, cereal production, which is primarily rainfed, is mainly constrained by drought due to the low rainfall accompanied by high temperatures. cereals have been tradi-tionally grown following a fallow period...

applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...
