effect of different amounts of sulfur fertilizer (0, 50, 100, 150, 200, 250 kg/ha) and 200 kg/ha of thiobacillus inoculant on yield, quality and storability of two edible onion cultivars red rey and white qom were investigated. the experiments were conducted at experimental field and laboratories of the department of horticulture, seed and plant improvement institute, karaj, iran in 2007-08 cro...

milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...

leaf analysis is a general method of estimating the fertilizer needs in fruit trees, but there exists a limited correlation between it and fruit quality. throughout the present study, fruits were harvested 10 weeks following full bloom and at the commercial maturity (6.2 brix) stages from thirteen different commercial kiwifruit orchards that had been fertilized with different fertilizers, the e...

Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high yield, dry matter content or drought tol...

Molecular markers are needed for enhancing the development of elite sweetpotato (Ipomoea batatas (L.) Lam) cultivars with a wide range of commercially important traits in sub-Saharan Africa. This study was conducted to estimate the heritability and determine trait correlations of storage root yield, dry matter, starch and β-carotene content in a cross between 'New Kawogo' × 'Beauregard'. The st...
