Nitrogen use efficiency and grain yield of corn hybrids as affected by nitrogen rates and sowing dates in subtropical environment

Effect of sowing time and nitrogen fertilizer rates on growth, seed yield and nitrogen use efficiency of quinoa (Chenopodium quinoa Willd) in Ahvaz, Iran

To study the effect of sowing time and nitrogen levels on growth, yield and nitrogen efficiency of quinoa cv. Titicaca, a field experiment was conducted at in 2017-2018 growing season research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Ahvaz, Iran. The experiment was conducted in split plot arrangement in randomized complete block design with four replications....

Sunflower summer-planting yield as affected by plant population and nitrogen application rates

Different sowing dates affected cotton yield and yield components

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

Dryland Wheat Grain Yield and Yield Components as Affected by Slope Direction and Residue Rates

Limited information is available on the effect of residues rates and slope direction on dryland wheat (Triticum aestivum L.) yield.  This study was carried out to determine the effects of residues rates and tillage direction on grain yield and yield components of the Sardary wheat in a dryland region in Zanjan. Five wheat residues rates (0, 25, 50, 75 and 100% surface cover) were applied and i...

Evaluation 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...
