The present study was based on the hypothesis that muriate of potash is a cheaper and rich source of potassium, but adversely affects the crops yield due to high Cl content. For this reason both column and field experiments were conducted to study the effect of potassium rates and sources on the availability of Cl, SO4 and K to maize crop growing on Haripur and Ghazi soils during 2004. In colum...

to determine the coefficients of c1 and c in mitscherlich-bray equation, critical level and fertilizer recommendation for potassium (k) as by mitscherlich-bray (mb) equation, an experiment in a randomized complete block design of 5 treatments and 3 replications was carried out in 12 irrigated wheat (triticum aestivum l.) fields in sarpol-e-zohab region during the 2007-08 growing season. the tre...

In semi-arid tropics, sugarcane yield and quality are affected by deficiencies in soil nutrients, including potassium calcium. We examined the effects of two different fertilizers, a traditional muriate potash (MOP) polyhalite (which contains calcium), on growth, yield, quality. Experimental treatments compared control 0 kg K ha?1 (T1) to applied as MOP only at 80 (T2) 120 (T3), an equal split ...

Chloride (Cl−) is applied in coffee at rates as a “macronutrient” the form of muriate potash (MOP). Potassium (K+) one most demanded nutrients by plant, and MOP used fertilizers production. No scientific evidence shows how Cl− with influences growth, nutrient uptake, nitrogen use efficiency (NUE). In order to address these questions, greenhouse trial over two years field four were conducted. Th...

BACKGROUND & OBJECTIVES Studies were conducted to determine the effect of ammonium sulfate (AM) and muriate of potash (MOP) fertilizers on survival and development of immature stages of Culex quinquefasciatus Say, a major vector of Bancroftian filariasis in Africa. METHODS Twenty I instar larvae each were added in four doses of each fertilizer dissolved in one litre of deionised water and in ...

Application of fertilizers such as urea, diammonium phosphate (DAP) and muriate of potash in soil adversely affected the spore germination of Arthrobotrys dactyloides. Amendment of soil with urea at the concentrations of 1.0%, 0.5% and 0.1% completely inhibited spore germination and direct trap formation on the conidium, whereas muriate of potash delayed and reduced the spore germination even a...

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during 2014 on transplant aman rice var. BR11 (Mukta) under different levels of chemical fertilizers and green manures to evaluate its grain yield, quality soil fertility status with incorporation manures. The carried out in a split- plot design three replications. level (0, 100, 75, 50% recommended dose, RFD) plac...

The most common formsof S fertilizers in the northern Great Plains are ammonium sulfate (AS), thiosulfate (ATS), and elemental (ES). Among these, AS is preferred over others because of its readily available SO42– form, it can be blended with other dry fertilizer granules, but prone to leaching. Recently, industries introduced micronized (<100 μm) (MS) formulations hope that smaller particles wo...

A consideration of fertilizer materials furnishing the three' major plant foods reveals the fact that sources of phosphoric acid and potash have remained almost constant while the sources of nitrogen have undergone decided changes. Superphosphate has been, and probably will continue to be, our main source of phosphoric acid in most fertilizer mixtures. In the year 1900, 79.8 per cent. of the to...
