The soil exchange complex consists of colloidal materials on which ion exchange phenomena occur allowing it to attract, retain, and exchange elements that have opposite electric charges. Since their mineral constituents (clay) and organic components (humus) are mainly of a negative nature retained or exchanged ion are predominantly cations. Historically, failing to monitor parameters like the e...

The study determined resource use efficiency in maize crop production by small-scale farmers the Central Agricultural Zone of Cross River State Nigeria. It specifically examined allocative resources used rainfed area. Primary data were to conduct study. Statistical tools employed multiple regression analysis and index (AEI). results revealed that variables farm size (x1), capital (x3), fertiliz...

Summer maize (Zea mays L.) is one of the dominant crops in the North China Plain (NCP). Its growth is greatly influenced by the spatial-temporal variation of climatic variables, especially solar radiation, temperature and rainfall. The WOFOST (version 7.1) model was applied to evaluate the impact of climatic variability on summer maize yields using historical meteorological data from 1961 to 20...

Sustaining and enhancing agriculture productivity has been recognized as one of the key pathways of reducing and eliminating hunger, poverty and malnutrition. Agricultural sector is regarded as the key component of the economies of many developing nations, including India. Globally, agriculture accounts for a large share of GDP, it employs a significant proportion of the labour force, represent...

Cotton yield under the rainfed farming system in tropical semi-arid regions is significantly decreased by prolonged dry spells. In this context, supplemental irrigation (SI) with treated wastewater emerges as a strategy for sustainability of agricultural production besides contributing to reduction fertilizer costs. The objective research was evaluate productivity, photosynthetic parameters, fi...

The demand for organic foods is increasing worldwide due to health and environmental benefits. However, there are several unanswered questions, such as: Do farmers generate higher profits? Will the cost of cultivation reduce compensate low yields? Can practice as per agriculture protocols obtain certification? literature on varies widely in terms profitability, yields costs products. A few stud...

Malawi's food and nutrition security heavily relies on rainfed agricultural production, which is prone to the effects of climate change, such as floods dry spells. To improve situation, policies have been established a guide assist in implementation technologies country. This study aims evaluate effect two national addressing nutrition, economics, by introducing modern/existing Phalombe distric...

This work aims to assess water quality for irrigated agriculture, alongside perceptions and adaptations of farmers climate change in the Main Ethiopian Rift (MER). Climate is expected cause a rise temperature variability rainfall region, reducing surface availability raising dependence on groundwater. The study data come from surveys with 147 living Ziway–Shala basin assessments 162 samples gro...
