【Objective】 In order to quantify the nitrogen accumulation and partitioning of protected cultivated tomato plant. 【Method】 The field experiments on cultivars and fertilizer were conducted in 2009 and 2010, and cultivars: B1, B2, and B3 were adopted.【Result】 The simulation models of nitrogen accumulation and partitioning for protected cultivated tomato plant were built by analyzing the relations...
in order to study the effect of biological and chemical fertilizers of nitrogen and phosphorus on some physiological, morphological and phenological traits of sunflower this study was carried out in eivanegharb (ilam province) in summer of 2011. treatments were arranged in split factorial based on rcbd with three replications. the main plot include 4 levels of phosphorus and nitrogen chemical f...
In order to maintain sustainable agriculture and prevent excessive use of chemical fertilizers, supplying part of the plant needs by organic fertilizers is necessary. In this respect, effects of nitrogen (N) source and rate on yield and yield components of forage sorghum was evaluated as a factorial experiment arranged in randomized complete blocks design with three replications at the Research...
Production of Mrenda (Corchorus olitorius) in Kenya has been low due to various reasons, such as poor agronomic practices like incorrect fertilizer rates. Observations from the Mrenda growing areas showed that there is high unmet demand for crop in local market and even for export. This is due to yields being low, 2-4 tons/ha as compared to expected yield of 5-8 tons/ha. Therefore, the main obj...
To study the effects of tillage system, planting method and of nitrogen fertilizer rate on the agronomic characteristics and seed yield of rapeseed (Brassica napus L.) Dalgan oilseed rape cultivar, as the second crop after rice, a split factorial experiment in complete randomized block design with three replications was carried out in two cropping seasons (2016-2018) at paddy fields of Rice Res...
to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...
BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
Supplementary irrigation moderates the damage caused by drought stress in rainfed agriculture. Meanwhile, the application of nano fertilizers and methanol as the foliar application can be considered as effective management strategies to improve production under dryland conditions. For this purpose, the effect of supplementary irrigation, nano fertilizer spraying, and methanol foliar spraying wa...
BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...
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...
