انرژی مصرفی در بخش کشاورزی با هدف تولید و فرآوری محصولات، به منظور ایجاد ارزش افزوده بسیار حائز اهمیت است. از طرف دیگر کشت گلخانه ای صنعت در حال رشد بسیاری از کشورها است و به دلیل تولید در خارج از فصل رشد، دارای مصرف انرژی بسیار بالایی می باشد. بررسی اثرات انرژی در تولید محصولات کشاورزی به بالا بردن میزان تولید و بهره وری، و سودآوری اقتصادی کمک می نماید. استان همدان یکی از مهم ترین مناطق کشاورز...
Agricultural productivity is significantly influenced by the restricted availability of irrigation water and poor soil health. To assess influence different potential moisture deficit (PSMD) regimes integrated nutrient levels on growth, yield, quality wheat, an experiment was carried out at research area University Agriculture, Faisalabad. The includes three PSMD (I1: 25 mm PSMD, I2: 50 I3: 75 ...
ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...
in order to investigate effects of optimum use of manure and nitrogen fertilizer on yield and yield components of corn single cross 704 (late maturing, non-prolific and dent) in different levels of irrigation water. a field study was conducted in 2005 year in agriculture experiment station of college agriculture, arak university (34o 32′ n, 50o 31′ e; 1759 m above mean sea level). design of exp...
A field experiment was conducted during 2013-14 to 2015-16 at Central Soil Salinity Research Institute, Regional Station, Lucknow find out the alternate rice (Oryza sativa L.)- wheat (Triticum aestivum L.) cropping system under partially reclaimed sodic soils. Four systems, viz. L.), sorghum (Sorghum bicolor)-berseem (Trifolium alexandrinum), sweet basil (tulsi) (Ocimum basilicum L.)-matricaria...
Rainfall erosivity, considering rainfall amount and intensity, is an important parameter for soil erosion risk assessment under future land use and climate change. Despite its importance, rainfall erosivity is usually implemented in models with a low spatial and temporal resolution. The purpose of this study is to assess the temporaland spatial distribution of rainfall erosivity in form of the ...
Rice-based cropping systems (RBCS) are a kingpin of global food security and rice fallow is one the largest (>14 m ha) RBCS. A three-year study was carried out to develop sustainable intensification options efficient nutrient management protocols RBCS with greater water energy productivity more profits. Rice-lentil, rice-linseed rice-rapeseed were tested in split-plot design practices involv...
abstract the aim of this survey is to compare utilization systems (cooperative, private and governmental) methods of energy consumption in soybean production and the evaluation of energy inputs effect in yield of soybean in moghan. for this purpose, the information were collected from 54 private farmers, 14 cooperative members farmers and 14 agro-industry units by questionnaire method. the maxi...
this study was conducted in 2008 at the research field of university of tehran, karaj. the experiment was designed as a randomized complete block design with three replications. treatments were: atrazine 1kg/ha, alachlor 4kg/ha, atrazine+alachlor (1+4) kg/ha, nicosulfuron 80 g ai/ha, furamsulfuron 45g ai/ha, rimsulfuron 25g ai/ha, nicosulfuron+furamsulfuron (80+45) g ai/ha, nicosulfuron+rimsulf...
In order to investigate the effect of source and rate of nitrogen fertilizer on yield and quality of sweet corn, a field study was conducted in 2011 cropping season in Agriculture Experiment Station of College of Agriculture, University of Guilan. A randomized complete block design with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 46, 92 and 138 kg ...
