Finger millet is extensively cultivated in the tropical and sub-tropical regions of Africa known to save lives small income farmers from starvation at times extreme drought. Therefore, this field experiment was carried out study integrated effect vermicompost inorganic fertilizer blended NPSB with urea on yield components finger millet. Treatments consisted four levels (25, 50, 75, 100%) three ...

nitrogen concentration, temperature and light intensity. Nitrogen is one of the essential nutrients critical for the cultivation of algae due to its role in growth and regulation of metabolism [1]. It is well documented that there are three different sources of nitrogen such as nitrate, ammonia and urea, which are absorbed by microalgae [2,3]. Urea is known to contain approximately 46.7% nitrog...

This paper deals with the Markov modeling and reliability analysis of urea synthesis system of a fertilizer plant. This system was modeled using Markov birth–death process with the assumption that the failure and repair rates of each subsystem follow exponential distribution. The first-order Chapman–Kolmogorov differential equations are developed with the use of mnemonic rule and these equation...

Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...

A field plots experiment was carried to investigate the influence of soil applications of neem-based (Achook and Nimbidin) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living and plant-pathogenic nematode populations and crop productivity. Data regarding the results showed that all the treatments significantly decreased the number of plant-paras...

Due to the continuous creation of organic granular fertilizers new composition, there is a lack knowledge about their properties and influence norm on spreading efficiency. To increase efficiency use fertilizers, aims are properly choose most rational parameters fertilizer norms, considering characteristics fertilizer. determine this quickly with lower costs, various theoretical models computer...

There is no specialized equipment designed to spread granular cylindrical organic fertilizer in the soil. are also rational recommendations available on how this type of fertilizer. Mineral spreaders most often used for spreading granulated However, these fertilizers significantly different from mineral fertilizers. Due differences, unevenly, and does not reach required working width. Furthermo...

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...
