soil and water salinity damage and decrease canola yield. however, plant yield should be increased using effective methods. this study aimed at investigating the effect of sulfure application fertilizers on canola yield. to this end, the experiment was conducted in split plot arrangement based on randomized complete blocks design with three replications at shavoor research station in south west...

To determine the effect of inorganic N fertilizer on the incidence of yellow stem borer (YSB), Scirpophaga incertulas Walker and on grain yield, yield attributes and bio-chemical characters of local paddy cultivar Tulaipanji, a field experiment for three consecutive years (2007-2009) was carried out by randomized block design in pesticide untreated field. Treatments comprised of seven different...

management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

in order to study the effect of different levels of nitrogen and sulfur fertilizers on yield, yield components, content of some elements, qualitative and quantitative traits of spring safflower (serin cv.) an experiment was conducted at agriculture and natural resource research station of ardabil in 2008. this experiment was carried out in factorial experiment in completely randomized block des...

to determine the effect of farm slopes on yield and some agronomic traits of wheat under different fertilizer treatments, an experiment was performed as split plot based on randomized complete block design with three replications in piranshahr in 2011-2012. treatments consisted of farm slope at four levels: (zero, 3, 6 and 10 %) as the main plots and combination of different fertilizer at five ...

Soil fertility improvement is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of chemicals. Since crop production and soil normal flora are affected by input of chemical fertilizer. Biofertilizer microorganisms make the nutrients available to plants. The present study was concerning to isolate of some Pseudomonas fluo...

Increased interests in low-input agriculture in recent years has seen the growing developmentin the use of commercial biological inoculants to increase the mobilization of key nutrients suchas nitrogen (N), phosphorus (P) and potassium (K) to enhance their availability to crop plants.The objectives of this field experiment with tobacco were to determine i) reduced rates ofinorganic fertilizer c...

A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t ha 1 each). Results showed that so...
