The potential for non-point-source pollution of surface waters from agricultural lands continues to be a concern. Our objective was to determine the effect of surface residue management and fertilizer application timing in regards to soil moisture conditions on nutrient losses in runoff. Studies were conducted using a rainfall simulator that applied 125 mm h-1 for 3 h to an Austin (Udorthentic ...

in order to study the effect of fertilizing treatments and limited irrigation regimes on yield and yield components of isabgol, a field experiment was conducted at experimental farm of college of agronomy and animal sciences, university of tehran. the experimental design was a split plot based on a randomized complete block design with three replications. in this research four irrigation regime...

in order to studying the effect of conventional fertilization and organic fertilizeron growth, yield and nitrate accumulation of spinach, a greenhouse experiment was carried out in factorial based on random complete design with three replications in a commercial greenhouse located at lahijan. treatments were three levels of municipal soil waste compost (0, 50 and 100 t ha-1), five chemical fert...

Upland rice is typically grown under slash-and-burn systems in the mountainous regions of northern Laos by resource-poor farmers for subsistence. Upland rice cultivars are all traditional and no fertilizer inputs are used. In these systems, grain yields average only 1.7 t/ha. A multi-site experiment was conducted in Luang Prabang province to examine cultivar and fertilizer effects on grain yiel...

in order to investigate the effect of fertilizer types and irrigation regimes on quality criteria of three medicinal plants: lavander, rosemary and hyssop, an experiment was conducted at research field of faculty of agriculture, ferdowsi university of mashhad, during two growing years of 2007-2009. a split plot design with three replications was used. treatments were three irrigation intervals ...

Growth and production strains need to be capability tested in many different environmental conditions. The research aims obtain efficient against the use of phosphate fertilizer best dose TSP for growth soybean strains. study used two-factor Factorial Group Randomized Design (RAKF) method. first factor is with 3 levels, namely P1=25 kg/ha, P2=50 P3=75 kg/ha.The second Factor 5 treatments were o...

An experiment was conducted to study the effect of municipal solid waste compost (MSWC) on growth, yield and protein content as well know combined application MSWC NPK fertilizers in rice (cv. BRRI dhan49). There were six treatments including- T0 = Control (No fertilizer or no MSWC); T1= 100% Recommended Doses Fertilizers (RDF) NPK; T2 (MSWC @ 5 t ha-1+ 75% RDF); T3= 7. 5t 50% T4= 10 ha-1 + 25%...
