The role of tomatoes as nutritive vegetable crop in the diet of most humans has been stressed or advanced by many scientists. This study therefore, assessed the profitability of tomato production using organic and inorganic fertilisers on a typical irrigated soil in Hong Local Government Area, Adamawa State, Nigeria, with the intent of ensuring a more acceptable measure of sustainability among ...

Diseases caused by plant pathogens significantly reduce growth and yield in agricultural crop production. Raising immunity in crops is therefore a major aim in breeding programs. However, efforts to enhance immunity are challenged by the occurrence of growth inhibition triggered by immunity that can be as detrimental as diseases. In this review, we will propose molecular models to explain the i...

In the present study, bioaccumulation of REEs in Zea mays L. (corn plant) has been analyzed. The role of Rare Earth Element (REEs) in physiology and biochemistry of corn plant have been studied. Physiological characters like peroxidase (POD) and superoxide dismutase (SOD) activities, biochemical analysis of chlorophyll, carotenoids and phenol contents have also been carried out. The plant growt...

The current challenges crop production faces in the context of required yield increases while reducing fertilizer, water and pesticide inputs have created an increasing demand for agronomic knowledge and enhanced decision support guidelines, which are difficult to obtain on spatial scales appropriate for use in a multitude of global cropping systems. Nowadays crop models are increasingly being ...

Issues of enhanced food security depend primarily on increasing agricultural production. Given this challenge, existing and new, appropriate technologies need to be integrated into agricultural research, to focus on the problems related to improving nutritional security. Among the different approaches, mutagenesis and the isolation of improved or novel phenotypes in conjunction with conventiona...

Worldwide land consolidation policies have been used during decades to improve efficiency in crop production through the consolidation of fragmented agricultural lands. At a landscape scale the effect of these policies that promote higher clustering of homogeneous crops is questionable, as spatial patterns influence the probability of exotic pests arriving and spreading across the landscape. Th...
