water deficit and low nitrogen content of soil are the two major yield limiting factors in most maize (zea mays l.) producing areas. the objective of the current research was to evaluate the relationships between photosynthetic water and nitrogen use efficiency at different levels of soil moisture and nitrogen contents. a factorial experiment, based on completely randomized design with 3 replic...

Raised-field agricultural systems were exploited extensively by pre-Columbian Andean civilizations and now are used less extensively by contemporary Bolivian and Peruvian farmers as a method for farming the perennially wet soils of the intermontane pampas of the Andean high altiplano. The raised-field agricultural systems are linear or semi-linear raised planting platforms interspersed with sha...

The application of controlled-release fertilizers (CRF) at the time of planting offers a means to improve the establishment of forest tree seedlings. As compared to conventional fertilizers, the gradual pattern of nutrient release from CRF may better coincide with plant needs, minimize leaching, and improve fertilizer use efficiency. Many different CRF types are available and products differ in...

the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...
