Continuous application of phosphatic fertilizers in association with its low recovery results the insoluble legacy P buildup agricultural soils. In this study, a field experiment was conducted maize hybrid COH(M) 6 to know effect different activators (Farmyard Manure, Humic acid, Phosphorus Solubilising Bacteria, and Phytase) on increasing phosphorus (P) availability. The were combined applied ...

in order to study the effects of different irrigation regimes and nitrogen fertilizer levels on yield and yield components of chickpea (ilc482), a field experiment involving chickpea genotype ilc482 was conducted as factorial arrangement based on a randomized complete block design with four replications in the agricultural research station, ferdowsi university of mashhad during growing season o...

A field experiment was conducted on almond (Prunus dulcis) to study the effect of N&K fertigation on growth, yields and leaf nutrient status over two seasons (2011 and 2012) in Srinagar, Jammu and Kashmir, India. There were six treatments, namely, T1--100% recommended dose of fertilizers as soil application, T2--100% RDF through fertigations, T3--75% RDF through fertigation, T4--75% RDF through...

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...

to investigate the effects of intercropping of basil (ocimum basiilicum l.) and cowpea (vigna unguiculata l.), different levels of nitrogen fertilizers on basil and cowpea yield, an experiment was carried out during 2010 and 2011. experimental factor were included weed treatment (weeding and unweeding), three levels of nitrogen fertilizer (0, 50 and 100 kg ha-1), different planting ratio, (p1: ...

in order to study the effect of planting pattern and herbicide application on corn (zea mays l.) grain yield and weeds control, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 l...

sunflower (helinathus annuus) is a susceptible host to the holoparasite hemp broomrape (orobanche ramosa) in central parts of iran, causing yield loss due to severe infestations. a field study was conducted in 2006 to evaluate the efficacy of glyphosate for controlling the parasitic weed hemp broomrape in sunflower. glyphosate was applied once or twice at five rates ranging from 0.075 to 0.450 ...

in order to study the effect of soil nitrogen content and water hardness on glyphosate efficacy on common lambsquarter (chenopodium album l.) and redroot pigweed (amaranthus retroflexus l.) control, an experiment was carried out as a completely randomized design in a factorial arrangement with three replications. experimental treatments were included soil nitrogen content (18, 50, 90, 200 and 3...
