Mazandaran province is an important area in rice cultivation but salinity is one the biggest constraint to obtain crop potential yield in some part of the coastal line of rice cultivated area in northern Iran. In order to find tolerant varieties and study the reaction of some newly released high yielding varieties to different levels of salinity of irrigation water a Factorial experiment was c...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
among investments in different sections of economy, investment in agriculture is great importance. in addition to increasing production and job opportunities in agriculture, investment in this section will help to increase these in other sections as well, due to back and front relations with other economic activities. due to the fact that investment does not yield rapidly, and it takes some tim...
Genetic and non-genetic correlations of the average somatic cell score (SCS) at different stages oflactation (100, 150, 200, 305 and 365 days in milk) with lactation performance were estimated based on thefirst lactation records of Iranian Holstein calving during 2000 to 2009. (Co) variance components wereestimated using derivative-free REML based on multiple traits animal models. The estimated...
Only leaf reduction (Cultural measure), in treatment T4 [treated with removal above 15 inches (38.10 cm) from ground level], maximum yield (2185.00 kgha-1) was found resulted 21.64% more over the control. T3 [10 (25.40 cm)] and T5 [20 (50.80 gave similar response having 20 20.68% increased The lowest severity (21.38 PDI) that statistically identical to [15 a decrease trend of 58.28%, 50.26% 42....
Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...
Nowadays application of soil conditioners for mitigation and reduction of runoff is a current method. Considering the advantages of Polyacrylamide (PAM), this study was arranged to evaluate impacts of this soil conditioner on soil infiltration rate, runoff and erosion control. To fulfill the goal, a factorial experiment in a completely randomized design was carried out with four PAM treatments ...
irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of iran. the average grain yield of barley in these areas is 2,000 kg/ha. wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. zahak barley cultivar was initially selected from international barley germplasm received from cymmit and based on...
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 ...
