Abstract This study was conducted to compare the content of carbon in soil and biomass vegetation various types sub-optimal dryland Aceh Besar district, Indonesia. Soil samples were collected from seven depths 0 100 cm under 12 land uses including primary forest, secondary pine Eucalyptus forests, teak forest shrubs, shrublands, grasslands, mixed gardens, moorlands, rainfed rice fields, bare la...

Intermittent drought and an incidence of grain mold disease are the two major constraints affecting sorghum production productivity. The study aimed at developing drought-tolerant varieties possessing a high protein content tolerance to with stable performance using additive main effects multiplicative interaction (AMMI) genotype × environment (GGE) biplot methods. Systematic hybridization amon...

in order to study of drought tolerance in bread wheat genotypes, this study was conducted in maragheh dryland agricultural research station. the study included two experiments and the statistical design of each experiment was a rcbd with four replications, and 20 bread wheat genotypes that were compared under drought stress (rainfed) and supplementary irrigation. analysis of simple variance sup...

The study was undertaken to evaluate the effect of foliar sulphur (S) nutrition through Ammonium Thiosulphate (ATS) under conservation management on growth, photosynthetic efficiency and productivity rainfed pearl millet in dryland ecologies New Delhi 2021 2022 crop years. established (ZTCRret) achieved significantly higher growth rate (CGR) relative (RGR) as a result improved photosynthesis te...

Plastic mulching, given its positive effects on temperature and water retention, has been widely used to solve shortages nutrient scarcity in rainfed agricultural soils. This practice affects the physical chemical processes of soil, including carbon nitrogen cycling. However, research into microbe-mediated cycling soil with plastic mulching is still limited. In this study, structures functions ...

In many crop producing areas of the world there are reports of yield decline and loss of productive potential in soils. Little is known about the long term effects of sugarcane monocropping on changes in physical, chemical and biological properties of soils. The aim of this study was to quantify the physical and chemical condition of soils under sugarcane production in northern Kwazulu-Natal, a...

Background. Cardiac rehabilitation program is aimed at reducing secondary risk factors and improving function in patients undergoing coronary artery bypass grafting run which ultimately may delay or reduce mortality in patients. A major component of cardiac rehabilitation program is exercise. Objective(s). This study is aimed at evaluating the effect of aquatic and dryland training on Perox...

In this study, we extend a model of daily dryland dynamics by parameterizing a modified version of a minimalistic annual model to examine how the statistical structure of annual rainfall and grazing intensity interact to influence dryland vegetation. With a Monte Carlo approach, an ensemble outcome provides a statistical description of likely dryland vegetation dynamics responding to variations...

Water is the most production limiting factor for dryland cropping systems in semiarid Great Plains environments. Evaporation is responsible for the greatest amount of water loss and management practices such as notill have been adopted to reduce evaporative losses. Less is known about the magnitude of water loss due to runoff. An objective of this study is to estimate an expected range in rainf...

Dryland ecosystems cover one third of the earth’s total land surface, comprise areas with a ratio of average annual rainfall to evapotranspiration of less than 0.65 (MEA, 2005). These regions are fragile environments characterized by unreliable rainfall patterns and support livelihoods of over 2.5 billion people (Reynolds et al., 2007). Widespread episodes of drought, heavy precipitation and he...
