In Nepal, blanket fertilizer recommendations without considering diverse soil types, nutrient status, climate and crop management practices along with imbalanced fertilization by farmers, mainly “urea fertilizer,” have resulted in reduced nitrogen use efficiency (NUE) productivity tomato production. Optimizing the rate of (N) fertilizer, application time improved methods could increase yields N...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...

to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...

According to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. Experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

A field experiment was conducted for two consecutive seasons (2009/10 and 2010/11) in the Demonstration Farm of the Faculty of Agriculture at Shambat-Sudan, to study the interactive effect of nitrogen fertilization and rhizobium inoculation on nodulation and yield of soybean (Glycine max [L.] Merrill) plants. The experiment was laid out in a randomized complete block design with four replicatio...

introduction nowadays oilseed crops are considered as the second most important sources of energy in the diet. in this regard, cultivation of oilseed crops such as safflower (carthamus tinctorius l.) is important due to quality of oil seed and medicinal properties. different planting dates leads to adaptation of vegetative and reproductive growth of plant to temperature, day-length and various ...

The objective of this study was to examine the impact of starter nitrogen fertilizer on soybean root activity, leaf photosynthesis, grain yield and their relationship. To achieve this objective, field experiments were conducted in 2013 and 2014, using a randomized complete block design, with three replications. Nitrogen was applied at planting at rates of 0, 25, 50, and 75 kg N ha-1. In both ye...

The effect of twelve different rates of nitrogen and phosphorus fertilizers on growth and yield of maize (Zea mays L.) in southern Nigeria was evaluated between June and October, 2007. The results of the study showed that application of 120kgN/ha + 0kgP/ha and 60kgN/ha + 40kgP/ha significantly increased the growth of maize than other treatments. The application rate of 120kgN/ha +40kgP/ha signi...

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...
