Nitrogen Time of Application Impact on Productivity, Water Use Efficiency and Agronomic Efficiency of Maize in a Semi-arid Environment

Effect of Water and Nitrogen Management on Water Productivity and Nitrogen Use Efficiency of Wheat in a Semi-arid Environment

A field experiment was carried out during 2009-11 on a sandy loam soil of IARI, New Delhi on wheat with four levels of irrigation (rainfed, irrigations to replenish 30, 60 and 100% moisture deficit from field capacity) as main plot factors and four levels of nitrogen (0, 30, 60 and 120 kg N/ha) as subplot factors in a split plot design. The soil moisture storage in the profile showed inverse re...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment

Effect of Nutrition Management and Application of Zeolite on Fertilizer Use Efficiency and Water Productivity in Two Maize Cultivars (Zea mays L.) under Deficit Irrigation Conditions

Abstract: To investigate the effect of nutrition management along with zeolite application on the fertilizer use efficiency and irrigation water productivity of two cultivars of maize under deficit irrigation conditions, a field experiment was carried out. The experiment was conducted at Soil and Water Research Institute, Karaj, Iran, in 2015 and 2016, in the form of a   factorial split plot...

Impact of controlled release urea on maize yield and nitrogen use efficiency under different water conditions

Controlled release urea (CRU) has been widely adopted to increase nitrogen (N) use efficiency and maize production, but the impacts can range widely depending on water availability in the soil. In an experiment using Zhengdan 958 (a popular summer maize hybrid), three levels of water treatments (adequate water condition [W3], which maintained soil moisture at about 75% ± 5% of the soil's field ...

increased water productivity of wheat under supplemental irrigation and nitrogen application in a semi-arid region

limitations of water and nitrogen in soil usually restrict plant growth. the objective of this study was to evaluate the effects of different amounts of supplemental irrigation at different growth stages and application of different rates of nitrogen fertilizer on grain yield and water productivity of wheat cultivars. a field experiment was conducted in the agricultural research station of shah...
