introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...

in order to evaluate the efficiency of inoculation of chickpea seeds with mesorhizobium and application of nitrogen and zinc on yield and yield components of rainfed chickpea an experiment was carried out in research station of shirvan-chardavel, ilam. the experiment was conducted in randomized complete block design (rcbd) with six treatments including mesorhizobium inoculation, nitrogen (40 kg...

An objective of study effect on inorganic sources NPK and Zn fertilizers soil health with the experiment was laid out in Randomized Block Design three levels (00%, 50% 100%), Zinc 100%) Recommended Dose fertilizer applied all treatments. The result showed that properties, growth yield chickpea were significantly affected by application Zinc. highest observed T9 (100%NPK +100% Zinc), followed T8...

Fruit peels of Banana, Pomegranate, Sweet lime and Orange are highly rich in potash, ion, Zinc etc. Above fruit peels powder were formulated from the trace amounts and gradually increased for the preparation of three formulations as Formulation 1, Formulation 2 and Formulation 3. Three different formulations were applied for plant growth in two methods such as fruit peel powder, fruit peel powd...

A study was conducted to determine if nitrate sources in ground water (fertilizer on crops, fertilizer on golf courses, irrigation spray from hog (Sus scrofa) wastes, and leachate from poultry litter and septic systems) could be classified with 80% or greater success. Two statistical classification-tree models were devised from 48 water samples containing nitrate from five source categories. Mo...

Nano fertilizers are new products which contain readily available nutrients in the nano scale range and are preferred largely due to their efficiency. This research was conducted to assessment the effect of nano chelated of micro nutrient on agronomic traits of Cowpea via factorial experiment based on randomized complete block design with four replications during 2016 seasonal year. The treatme...

Zinc (Zn) fertilizer is not currently recommended for rice grown on clay or clay loam soils in Arkansas. In 2003, eight field sites were established to evaluate the response of rice grown on clay soils to Zn fertilization. Shortly before or after seeding, granular Zn fertilizer was applied to the soil surface at rates of 0, 5, 10, and 20 lb Zn/acre. Tissue Zn concentration 10 to 14 days after f...

A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...

Nutritional management is an important factor in the success of crop production. In order to evaluate different level of nitrogen, potassium and zinc fertilizers on agro physiological characteristics of green bean a field experiment was conducted as split-plot based randomized complete block design in three replications, in Varamin university field research during 2011. The main plot included u...
