the current study was carried out to examine sugar beet growth pattern in climatic conditions of hamedan, iran and to recognize the factors affecting its quantity and quality as well as the physiological indices. two sowing date experiments were conducted on the basis of a randomized complete block design with four replications and 11 harvests. the plots were destructively sampled and the growt...

introduction legumes after cereals are the second source of human food and in iran they are the second most important food after the wheat. legumes protein is four times as much as that of grains and 10 to 20 times as much as that of glandular plants. in addition, beans are planted in iran in a wide area and knowing optimal farming factors can be an important step in increasing them. one of the...

conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...

In wheat, tillering and water-soluble carbohydrates (WSCs) in the stem are potential traits for adaptation to different environments and are of interest as targets for selective breeding. This study investigated the observation that a high stem WSC concentration (WSCc) is often related to low tillering. The proposition tested was that stem WSC accumulation is plant density dependent and could b...

a research trial was conducted during 2011-2012 to elucidate the effects of humic acid (ha) and npk to determine the optimum rate against different growth and floral attributes on tulip cultivar viz. ‘triumph’. the following five treatments t0 : (control), t1: 10 g/m2 npk (17:17:17), t2 : ha 0.75 ml (8%) + 10 g/m2 npk (17:17:17), t3: ha 1.00 ml (8%) + 10 g/m2 npk (17:17:17) and t4: ha 1.25 ml (...

Reference crop evapotranspiration (ET o), used to determine actual crop evapotranspiration, is often estimated from pan evaporation (EP) data. However, uncertainties in the relationship between ET o and EP often result in unreliable estimate of crop evapotranspiration. This study investigated the relationship between measured and estimated crop evapotranspirations, ET m and ET e, respectively, ...

Progress in crop improvement is limited by the ability to identify favourable combinations of genotypes (G) and management practices (M) given the resources available to search among possible combinations in the target population of environments (E). Crop improvement can be viewed as a search strategy on a complex G×M×E adaptation or fitness landscape. Here we consider design of an integrated s...
