Response 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 کاملEstimating Plant Dry Matter Productivity for AL-Sweeda Badia Rangeland (Syria) at Deferent Processing Levels of BKA, KVA Satellite Images
Estimation of plant dry matter to management of rangelands fast as well as high accuracy is important for managers. Research aims to compare Plant Dry Matter Productivity (PDMP) values estimated by Normalized Difference Vegetation Index (NDVI) derived from satellite images BKA, KVA according to different levels of satellite image processing, for AL-Sweeda Badia (Syria), during the April, July o...
متن کاملEffects of manure nitrogen on vegetables’ yield and nitrogen efficiency in Tanzania
Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...
متن کاملImprovement of crop yield in dry environments: benchmarks, levels of organisation and the role of nitrogen.
Crop yield in dry environments can be improved with complementary approaches including selecting for yield in the target environments, selecting for yield potential, and using indirect, trait- or genomic-based methods. This paper (i) outlines the achievements of direct selection for yield in improving drought adaptation, (ii) discusses the limitations of indirect approaches in the context of le...
متن کاملتأثیر کود نیتروژن بر عملکرد و کیفیت سه رقم سورگوم علوفه ای در شرایط آب و هوایی شهرستان رشت
In order to investigate effect of nitrogen fertilizer on yield and quality of three forage sorghum cultivars under Guilan climatological conditions a field study was conducted in 2010 cropping season at Rasht. A randomized complete block design with factorial arrangement with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 50, 100 and 150 kg N ha-1 fro...
