In order to evaluating the efficacy of biological and organic fertilizers in increasing soybean yield, an experiment was conducted in the research field of Bojnord Azad Islamic University in 2019 as randomized complete block design in split plots arrangement with three replications. The main plot included Hobbit and L17 soybean cultivars. The sub p...

Soilless growing is becoming an attractive option because of the unpredictable problems of soildue to fluctuating temperatures, moisture holding capacity, obtainability of nutrients, salinity, root aeration, undesirable microbial activities and nematode, disease and pest to overcome these problemswith soilless. Since the growthmedium relates to eve...

Winter rapeseed is relatively new introduced crop that is in competition with winter cereals especially irrigated wheat in Northeast of Iran. Farmers must to decide which of them is more economic and profitable for cultivation. Local farmers have a good technical cognition about wheat cultivation historically, so this crop has more chance for selec...

Safflower is an adapted plant with our country conditions. In order to study of safflower cultivars yield and yield components under different supplementary irrigation conditions an experiment was conducted in khorasan. The experimental design was split plot based on Randomized Complete Block Design with four replications. Factors were included fiv...

In order to determining the proper planting date for cold tolerant spring type cultivars of rapeseed, a two years experiment was done in Agriculture and Natural Resources Research Center of Khorasan-Razavi, Toroq Station in Mashhad , at North-east of Iran during 2006-2008 growing season. In this experiment seven planting dates with one month interv...

In order to evaluation of the potassium, zinc and manganese effects on agronomic traits of soybean, a factorial experiment was conducted on 2008 growing season with three replications at Kohne-kan research field in Bojnourd, Iran. This experiment was done based on RCBD design. Treatments were, potassium in three level(0, 80 and 160 kg/ha K 2 O in f...

In order to study the effect of water stress and potassium levels, growth indices and yield of sunflower a split plot experiment based on randomized complete block design(RCBD) was conducted with four replications during 2011 growing season in Bojnourd International Airport's field. Water stress was applied by irrigation regimes as main factor at t...

Simulation of dry matter partitioning and distribution of crop is an important means of predicting yield .In order to evaluation of leaf and pod partitioning coefficient among 13 spring rapeseed cultivars, an experiment was carried out in 2010 growing season at Agriculture and Natural Resources Research Station of Torogh , Mashhad. Experimental des...

To study on effect of PEG 6000 stress on germination and early seedling growth of B. juncea (L.) Czern. var. Ensabi an experiment was conducted in the laboratories of Institute of Biological Sciences, University of Malaya, Malaysia. Seed germination and final germination rate of B. juncea var. Ensabi significantly affected by PEG 6000 concentration...

Bio-fertilizers have a distinct role in soil fertility and crop production, especially in recent years. For evaluation of biological plant growth promoters on seed yield and its components in sesame cultivars, a factorial experiment was conducted with three replications, in research field of Islamic Azad University of Bojnourd over the 2011 growing...

Considering the importance of salinity in some regions of our province specially the lands under cultivation of oilseed rape, an experiment was conducted at greenhouse conditions for study the effect of four levels of salinity, ie. 2, 3, 6 and 9 ds/m produced from NaCl and CaCl 2 and different cultivars of oilseed rapes. The framework of experiment...

The viewpoint of rapeseed farmers in Khorasan Razavi province, in Iran, has a distinct correlation with their level of educational and technical knowledge that they are obtained from extensional resources. The farmers who studied technical leaflets, and were active in extensional programs and used the aural and ocular programs, had a very good leve...

On-farm collaboration allows farmers and researchers to share observations, and lets the researcher draw on the farmer's experience with a farm and its problems. This can be a good beginning for choosing topics suitable for demonstrations or research (Anderson and Lockeretz, 1991). The field study was conducted to evaluate yield comparison of seven...

Rapeseed is a new oilseed crop in Iran and its hectares has been currently expanding. Reproductive growth of the crop is exposed to water stress in many part of the country. In order to evaluation of yield, yield component and seed oil content of Brassica oilseed rape cultivars belong to Brassica napus, Brassica rapa and Brassica juncea species at...

The purpose of this study was to examine the relationship between participation of farmers in non formal education (NFE) and wheat production (BWP). The sample consisted of 170 male farmers randomly in Torbat Heydarieh, Iran.The instrument of data collection was questionnaire and reliability with Cronbach's coefficient alpha was 0.98. The results s...

This study refines the participatory management (PM) in agricultural extension education (AEE) by adopting a multidimensional approach. PM is a process where extension agent (EA) tries to provide a good situation for AEE and share significant degree of power with their farmers. The data were obtained from samples of 290 Iranian farmers in Torbat He...

In order to evaluate the yield and physiological indices of 13 spring cultivars of rapeseed , an experiment was conducted in 2007 growing season at Khorasan Razavi Agriculture and Natural Resources Research Center ,Mashhad-Iran. These cultivars were from three rapessed species belonged to Br assica napus, Br assica r apa and Br assica juncea. The e...

This study was conducted to investigate influences of drought stress in terminal growth duration on yield and yield components of spring canola, which is an oil seed plant. The experiment was conducted in RCBD with three replicates and in two conditions including: drought stress and control with nine cultivars of three different species during two...

Soil salinity threatens initial stages of emergence and early seedling growth in cool season grasses, although it may be tolerant in its adult stages. Today, seed priming has been known as an effective technique for improving seed germination, seedling vigor, and emergence rate and seedling establishment under different environmental stresses. A po...

More than 90 percent of Iranian domestic need for oil is imported. Carthamus tinctorius L.,one of the native plants in Iran, is tolerant to drought and salinity. Its seeds contain 35% high-quality oil and 15% protein. To study the effect of density, variety, and planting date on yield and yield components of safflower, an experiment was carried out...

Spinach (Spinaceae oleraceae L.) is one of the most enrichment leaf vegetable used by people in the globe. Inadequate micronutrients especially zinc in most Iranian soils have formed a major constraint to spinach production. Therefore, a study was conducted in 2008 growing season in Kohnekan region of Bojnourd to investigate the effects of foliar a...
