In order to determine the response of some tropical grass species to low light situations such as under plantation crops, seasonal cloud cover, etc., six tropical forage grasses were evaluated over a 20 month period on an Oxic Haplustoll in Hawaii (100 m above sea level) under four light regimes (100, 70, 45, and 27/, daylight using polypropylene netting) in the field. The forage grasses evalua...

in order to study the effects of nitrogen (n), boron (b) and sulfur (s) on yield, yield components, oil and protein content of safflower (carthamus tinctorius l.) an experiment was conducted in research station, college of agriculture, shahid bahonar university of kerman, using a local variety’’ isfahan’’. a randomized complete block design with three replications was used. treatments were all ...

in order to study the effects of nitrogen and phosphorous application on yield and physiological parameters of sugar beet polygerm seed (cv. 7233), this study was conductedin 2000-2001 in ardabil agricultural research station (alarough). the experiment was carried out with two factors including nitrogen in 4 levels (0 as control, 100, 200 and 300 kg n/ha) and phosphorous in 3 levels (0 as contr...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

introduction bean (vicia faba l.) has the great old history of crop cultivation to date would be pushed back to a fairly long day plant, resistant to frost and cool season crop and up to 5 degrees celsius tolerated. bean prefers wet and cold conditions. excessive heat may cause fetal growth problems, loss and reduce the number of seeds per pod bean flowers to the growth of plant and fruit set o...

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...

The combination of organic manure and inorganic fertilizer plays a role in increasing crop yield nutrient efficiency, but such effectiveness varies with crop, soil, management, climate. Here, 6-year field experiment was conducted to evaluate the effects substituting on yield, grain protein content, nitrogen phosphorus efficiency under winter wheat-summer maize cropping system Anthrosol. Five tr...

Sweet sorghum is a multi-purpose crop due to the use of all plant parts. The research was carried out under controlled conditions evaluate effect fertilization management on growth, grain yield and characteristics sweet grown as second in Mediterranean climate conditions. experiment two-factor randomized plot trial with 20 treatments combination 5 nitrogen levels (0, 50, 100, 150, 200 kg N/ha) ...
