The results of the research on assessment effectiveness application biological fertilizer Humistim and micronutrient fertilizers MicroFeed Complex Extra Phosphorus in cultivation spring wheat under conditions Kursk Region are presented. As a result research, it was found that preparations (Humistim, Phosphorus) contributed to better growth development wheat, reduced leaf-stem diseases, increase...

ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...

Information on maximum grain yield and its attributes are limited for double-season rice crop grown under the subtropical environment. This study was conducted to examine key characteristics associated with high yielding double-season rice crop through a comparison between an integrated crop management (ICM) and farmers' practice (FP). Field experiments were conducted in the early and late seas...

Tef [Eragrostis tef (Zucc.) Trotter] is the major cereal crop in the Horn of Africa, especially in Ethiopia where it is a staple food for over 60% of its 90 million population. The crop performs better than other cereal crops under extreme environmental conditions. The grain of tef is not only nutritious but also gluten-free, the cause for celiac disease, which affects humans world wide. The ob...

Nitrogen is one of the most important factor affecting maize (Zea mays L.) yield and income of smallholders under semiarid climates. Field experiments were conducted to investigate the impact of different N-fertilizer sources [urea, calcium ammonium nitrate (CAN), and ammonium sulfate (AS)] and rates (50, 100, 150, and 200 kg ha-1) on umber of rows ear-1 (NOR ear-1), number of seeds row-1 (NOS ...

plant photosynthetate partitioning is important in seed yield formation. in this research, in order to study grain filling procedure of chickpea in the presense of drought stress and nitrogen (n) fertilizer on remobilization rate, final grain weight and grain yield were measured. experiment was performed in an split-factorial using randomized complete block design with three replications. droug...

Background: The application of biochar as a soil amendment has achieved popularity and has been found to improve considerably soil nutrient status and plant productivity in low fertile soils. Methods: This study used two different methods to apply sewage sludge and sewage sludge biochar with three replicates in a completely randomized block design. The experiment included (1) control, (2) mulc...

Grasspea (GP) (Lathyrus sativus) is a drought-tolerant legume that can be grown for forage and grain. It has potential value to be used as a nitrogen-fixing crop in dryland rotations with non-legume grain crops. However, the agronomy of GP for the Central Great Plains region have not been investigated. The objective of this research was to compare the grain and biomass yield, as well as N accum...
