Legume/maize intercropping has been practiced in many countries as a sustainable cropping system, but the effects of legumes with maize together N application rates on biomass yield, quality, water-use efficiency (WUE), and nitrogen use (NUE) are limited under arid conditions Northwest China. Field experiments were carried out areas China from 2019 to 2020 three planting patterns (LM: Dolichos ...

Maize and soybean intercropping is a cereal-legume pattern that not only increases grain yield but also improves the nutritional value of silage. Experiments were conducted in summer season to compare composition forage silage quality mono-cropped maize intercropped maize-soybean harvested at two stages maturity. The main treatments one sole crop (SM) four patterns (one-row one-row (1M1S), two-...

Maize is a staple summer crop grown in the hilly areas of Nepal, where the soil is fragile and fertility is declining over years due primarily to degradation of natural resource base, high rates of soil erosion, increased cropping intensity and inadequate replenishment of soil nutrients. Forum for Rural Welfare and Agricultural Reform for Development (FORWARD) with the financial support from Hi...

Maize (Zea mays L.) is a host to numerous pathogenic species that impose serious diseases to its ear and foliage, negatively affecting the yield and the quality of the maize crop. A considerable amount of research has been carried out to elucidate mechanisms of maize-pathogen interactions with a major goal to identify defense-associated proteins. In this review, we summarize interactions of mai...

BACKGROUND Plants depend on their root systems to acquire the water and nutrients necessary for their survival in nature, and for their yield and nutritional quality in agriculture. Root systems are complex and a variety of root phenes have been identified as contributors to adaptation to soils with low fertility and aluminium (Al) toxicity. Phenotypic characterization of root adaptations to in...

water and nutrient availability are two major constraints to forage maize production in arid and semi-arid areas; however, the effect of different n levels from organic and inorganic sources on nutrient (i.e., n and p) efficiency under drought stress conditions is not well known for maize faming. thus, a field study was conducted with the objective of determining the effect of n fertilization a...

BACKGROUND Sugarcane mosaic virus (SCMV) is an important virus pathogen in crop production, causing serious losses in grain and forage yields in susceptible cultivars. Control strategies have been developed, but only marginal successes have been achieved. For the efficient control of this virus, a better understanding of its interactions and associated resistance mechanisms at the molecular lev...

Corn smut fungus (Ustilago maydis [DC.] Corda) is a globally widespread pathogen affecting both forage and sweet maize hybrids, with higher significance in maize. Remote sensing technologies demonstrated favorable results for disease monitoring on the field scale. The study focused changes vegetation index (VI) values influenced by pathogen. In this study, four two hybrids were examined. Artifi...
