Enhanced nitrogen use efficiency (NUE) in turfgrass systems comprises several factors, including more efficient uptake and assimilation of applied (N), as well reduced N losses to the environment. The objectives current research were evaluate inter- intraspecific variation parameters two Agrostis species, creeping bentgrass (Agrostis stolonifera L.) velvet canina L.), under field controlled env...
in order to study the effects of nitrogen and complementary irrigation on yield and its components of rainfed barley sahand cultivar, an experiment was conducted on split plot based on randomized completely block design with four replication in baft area at 2009-2010. factors were: four levels of nitrogen (0, 20, 40 and 60 kg/ha as pure nitrogen) from urea source as factor b and four levels of ...
The present study aims to investigate the effects of nitrogen fertilization and municipal waste compost on yield, yield components and some of the grain macronutrients of sweet corn. A field experiment was carried out as a split plot in randomized complete block design with three replications in 2015 at Agriculture and Natural Resources Research Center Zarghan-Fars, Iran. The main plot consiste...
the objective of this study was to evaluate the effect of plant population and nitrogen rate on yield and yield components of corn (zea mays l, hybrid 704) in 2008 at mamasani region, fars province. the experiment was conducted as a factorial based on randomized complete block design with three replications. experimental factors was four plant population (75000, 90000,105000, and 130000 plant h...
