A field experiment was conducted to evaluate the residual effect of rock phosphate and waste mica enriched compost on phosphorus and potassium supplying capacity under soybean crop grown after wheat in a Typic Haplustept. Enriched compost prepared using rice straw, rock phosphate, waste mica and Aspergillus awamori had higher chemical (total P, K, Ca, Mg and micronutrients) as well as biologica...

Previous investigational work on the nutrition on the strawberry has been concerned largely with the relationship of soil and fertilizer treatment to growth and yield (5). While these studies have increased greatly the knowledge of the fertilizer requirements of the strawberry, they did not describe the symptoms of mineral deficiencies nor show the mineral composition of the plant and fruit. It...

The nutrient contents of a widely-consumed leafy vegetable produce – Telfairia occidentalis using poultry manure (PM) and mineral fertilizer (Nitrogen, phosphorus and potassium-NPK) application were evaluated for comparison. PM at four levels (0, 5, 10 and 15 tonnes) and a standard rate of 90kg NPK per hectare was applied. Leaves were harvested for immediate analyses at 15 weeks after planting ...

in order to investigate the effect of vermicompost (vc) application on amount of micro elements in soil and plant organs of the medicinal plant of borage (borago officinalis), an experiment was carried out in split plot based on complete randomized block design with three replications in the research farm of the sari university of agricultural science and natural resources. fertilizer treatment...

in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207 during the period from December 2008 to April 2009 to study the role of potassium and sulphur on the growth, yield and oil content of soybean (Glycine max var.BARI Soybean-5). The experimental soil was clay loam in texture having pH of 6.3. The experiment included four levels of potassium viz. 0, 20, ...

A study conducted over three consecutive years examined the effects of using biochar, organic fertilizer and microorganisms on soil pH concentrations macro microelements in soil. tendency to increase was seen where biochar used. The highest concentration phosphorus found after application with addition microorganisms. most potassium treated together fertilizer, while magnesium fertilized alone ...

An experiment was conducted in the field of Plant Pathology Division, BARI, Cazipur, during Robi 2015-16, 2016-17 and 2017-18 cropping seasons to evaluate efficacy available plant nutrients against purple blotch disease tip-burn onion. Eight different viz. Potassium (ZnSO4 fertilizer), Phosphorus (TSP Boron (Boron Zinc Calcium (CaSO4 Copper (CuSO4), Silicon (silica gel) Manganese (MnSO4 fertili...

Between 2012 and 2015, a field experiment was conducted at the Brody Experimental Farm, Poznan University of Life Sciences, Poland. The following two experimental factors were used in duplicate: calcium sulfate (CaSO4) fertilization—two levels (0 500 kg ha−1); potassium (K) fertilization—four (0, 30, 60, 120 ha−1). soil pH (in H2O) enzyme activity (dehydrogenase, acid phosphatase, alkaline phos...

BACKGROUND: One of limitation factor in agricultural plants production in dry areas, supply requires water. Also nutrition crop management is a necessary strategy for achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assessment the effects of different irrigation regimes and several amount of nitrogen fertilizer on seed nutrition...
