in order to investigate the effects of vermicompost and chemical fertilizers on growth characteristics, yield and yield components of marshmallow (altheaeofficinalis l.), a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at faculty of agriculture, ferdowsi university of mashhad, iran, during growing season of 2012. experimen...
A experiment was lay out in order to evaluate the effects of different biofertilizers on yield and yield components of maize at the Lorestan provience, Iran. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitrokara (N1), O4 (N2), O6 (N3) and control (N4)) and three phosphate biofrtilizers ...
While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...
In order to study the effects of foliar application of phosphorus (P) and water deficit on yield and yield components of winter wheat (Triticum aestivum L., cv. Alvand), a split-plot experiment, with completely randomized blocks design and three replications, was carried out at the Research Farm of Boyer Ahmad Agricultural and Natural Resources Research Station, 13 km west of Yasouj, in 2008-20...
Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...
Fertilizer management is essential for achieving sustainable agriculture and protecting the environment. To evaluate the effect of Nitroxin bio-fertilizer application on quantitative and qualitative traits of corn hybrids a farm research was arranged via split plot experiment based on the randomized complete block design with four replications in 2013. Main plots were Included: use of the chemi...
In Iran, fertilizers are mainly applied directly to soil. In such conditions, the yield and fertilizer use efficiency are usually low. The simultaneous application of fertilizers and irrigation water (fertigation) is an appropriate alternative to increase the efficiency of applied water and fertilizers. The objective of this study was to investigate the effect of various irrigation and fertiliz...
to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
