this experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in iran. the experiment was a factorial design with three replications. treatments were four nitrogen biofrtilizers (control (n1), nitroksin (n2), azotobacter (n3) and supernitroplat (n4)) and three phosphate biofrtilizers ( control(p1), biosfer phosphate (p2) and ...
This study was carried out to evaluate the yield potential and other agronomic traits of nine genotypes of flax at two different spring planting dates: April 4 and May 5, 2003 and 2004, using a randomized complete block design with three replications at the Research Farm of Shahrekord University. The results showed that the effects of planting date and genotypes were significant on all of the t...
In order to evaluate the effects of foliar application of micronutrients (iron and zinc) and different harvesting times during seed filling on yield and mucilage percentage of psyllium (Plantago psyllium), a field experiment was carried out in 2009 at the Research Farm of the Faculty of Agriculture, University of Tabriz, Tabriz, Iran. The experiment was arranged as split plot based on randomize...
ارزیابی وضعیت تغذیهای چغندرقند با استفاده از روش DRIS و مقایسه آن با روشDOP در استان آذربایجان غربی
To establish DRIS norms in sugar beet (Beta Vulgaris L.) and compare them with DOP index, leaf samples were collected from 57 fields and N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were determined. On the bases of crop yield, the fields were divided into two groups with low and high yielding performances. Standard DRIS norms were established for the different nutrient ratios. DRIS indi...
In order to investigate the relationship among seed yield and its components in safflower, path and factor analysis were conducted using the agronomic and morphological traits of 32 genotypes. Genotypes were evaluated on the Research Farm of Isfahan University of Technology, using a randomized complete block design with three replications. The correlation coefficients showed that number of seed...
Soil amendment with pyrogenic carbon (biochar) is discussed as strategy to improve soil fertility to enable economic plus environmental benefits. In temperate soils, however, the use of pure biochar mostly has moderately-negative to -positive yield effects. Here we demonstrate that co-composting considerably promoted biochars' positive effects, largely by nitrate (nutrient) capture and delivery...
BACKGROUND Jatropha curcas L. is an oil seed producing non-leguminous tropical shrub that has good potential to be a fuel plant that can be cultivated on marginal land. Due to the low nutrient content of the targeted plantation area, the requirement for fertilizer is expected to be higher than other plants. This factor severely affects the commercial viability of J. curcas. RESULTS We explore...
This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
‘Yecora Rojo’ wheat (Triticum aestivum L.) and ‘Florida Petite’ tomato (Lycopersicon esculentum Mill.) plants were grown in monocultured or intercropped recirculating hydroponic systems to determine whether plant growth or yield would be affected by intercropping. Mean fruit weight was slightly lower (12%) for intercropped than for monocultured tomato plants. The number of tillers per plant was...
Cumin (Cuminum cyminum L.) is one of the most important cultivable medicinal plants in Iran and today, it is the second most popular spice in the world after black pepper. It is essential to know the relationships between yield and its components in cumin breeding programs. Therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine th...
