According to the results of competitive variety trials in 2010–2019, ecological stability and plasticity nine sunflower varieties three maturity groups were studied. The most stable yield Stepnoy 81 82, which belong extensive group, have been identified. High had Saratovskiy 20, 21, 85, 86 Slastena. These intensive type are well responsive varying growing conditions more demanding on a high lev...

Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...

This study aimed to analyze the economic feasibility of replacing soybean meal by sunflower cake in the diet of lambs. Twenty-eight non-castrated crossbred Suffolk lambs aged four months, with 21 kg average body weight ± 9 kg were used. These animals were distributed by weight category into 3 treatments (10, 20 and 30% dry matter (DM) addition of sunflower cake in replacing soybean meal) and co...

This paper aims at firstly evaluating the correspondence between Normalized Difference Vegetation Index (NDVI) products from Formosat-2 (F2) and SPOT sensors and then to perform a comparative analysis of two methods for retrieving Green Area Index from high spatial and temporal resolution satellite data (F2 and SPOT). For this purpose, an empirical approach using NDVI plus field data and a Neur...

Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...

In sunflower harvesting for decreasing the grain loss and increasing using efficiency of combines GIS technologies, namely equipped with GPS devices control sensors provides good results. This is explained that by fact a length 400-500 mm, cut baskets did not partially fall on divider-guide, 700-800 seed losses increased due to uncut baskets, since an increase in divider-guide bent some stems f...
