Growth and yield responses of two forage sorghum cultivars to different nitrogen fertilizer rates
In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...
متن کاملAssessing Nitrogen Use Efficiency and Nitrogen Loss in a Forage-Based System Using a Modeling Approach
In intensive agriculture, N supply often exceeds crop requirements, even in nitrate vulnerable zones (NVZ). In farmland, the N surplus gives rise to NO3 ́ leaching and consequent groundwater pollution. The present study aimed at proposing measures to reduce N leaching and hence improve N efficiency in a buffalo livestock farm located in the NVZ of Latina plain (Central Italy). The farm was culti...
متن کاملEvaluation of Seed Yield, Its Component and Nitrogen Use Efficiency of Sorghum in Response to Nitrogen and Nitroxin Fertilizers
BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...
متن کاملResponse of Fresh Forage, Dry Matter and Yield Components of Sorghum to Different level of Nitrogen and Cutting Height
BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nitrogen is generally a limiting nutrient in crop production, and especially in sorghum, as it has been said to be the most responsive nutrient for its production. OBJECTIVES: Current study was conducted to assessment effect of urea fe...
متن کاملNutrient removal efficiency by floating macrophytes; Lemna minor and Azolla pinnata in a constructed wetland
The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...
