Crop height not only determines plant resistance to lodging and crowding, but also affects crop architecture, apical dominance, biomass, mechanical harvesting. Plant is determined by the internode elongation, regulated genes involved in gibberellin (GA) brassinosteroid (BR) biosynthesis or related signaling networks. Plants’ genetic inability synthesize respond GAs BRs induce dwarfness. However...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

this research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. effect of peanut shells composts on the growth of viola tricolor and marigold was investigated during seven months. peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. plant g...

Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 2003) and at two locations in Khartoum S...

The use of airborne CARABAS-II VHF (20–90 MHz) SAR data for retrieval of forest parameters has been investigated. The investigation was performed at a test site located in the southwest of Sweden consisting mainly of Norway spruce forests. Regression models predicting forest parameters from radar backscattering amplitude were developed and evaluated. The results showed a linear relationship bet...

The management of facial defects has rapidly changed in the last decade. Functional and esthetic requirements have steadily increased along with the refinements of surgery. In the case of advanced atrophy or jaw defects, extensive horizontal and vertical bone augmentation is often unavoidable to enable patients to be fitted with implants. Loss of vertical alveolar bone height is the most common...

The objectives of this work were to determine the sample size (number plants) needed estimate mean cut and grazing sorghum (Sorghum bicolor (L.) Moench), Nutribem cultivar, traits investigate linear relations among traits. At 86 days after sowing, 110 plants selected at random. evaluated for each plant were: height, stem diameter, number nodes, leaves, leaf fresh matter, shoot dry matter. was d...
