Xanthium Strumarium L. Impact On Corn Yield And Yield Components, Zahid Hussain, Khan Bahadar Marwat, John Cardina, Ijaz Ahmad Khan
Turkish Journal of Agriculture and Forestry
Xanthium strumarium L. is a major weed affecting flour corn in Khyber Pakhtunkhwa Province of Pakistan. Studies conducted in 2006 and 2007 evaluated corn yield and yield component responses to competition from X. strumarium over a range of corn populations (5, 7.5, 10, and 12.5 plants m^{-2}) and X. strumarium densities (0, 2, 4, 6, 8, 10, and 12 plants m^{-2}). Flour corn yield and yield components (grains ear^{-1}, 1000-grain weight, harvest index, and days to silking) were significantly correlated with and affected by corn population, weed density, and the interaction between them. The percent reduction in grain yield was …

Impact Of Early Cropping On Vegetative Development, Productivity, And Fruit Quality Of Gala And Braeburn Apple Trees, Dragan D. Radivojevic, Jasminka M. Milivojevic, Cedo Dj. Oparnica, Todor B. Vulic, Boban S. Djordjevic, Sezai̇ Erci̇şli̇
Turkish Journal of Agriculture and Forestry
The effects of 5 crop load levels (all fruit removed and 10, 20, 30, and 40 fruit per tree) in the second growing year on vegetative growth, productivity, and fruit quality were studied in apple cultivars Gala and Braeburn on M9 rootstock in the second and the third leaf. An increase in vegetative growth was observed on the defruited trees in the second growing year. The highest crop load of 40 fruits per tree reduced average fruit weight by 18.7% in Gala compared to those obtained on the trees carrying the lowest crop load (10 fruits per tree). The reduction …

In this study, the combined ability effects and heterosis were determined for number of days to anthesis (AT), plant height (PH), fertile tillers plant^{1} (FT), spike length (SL), spikelets spike1 (SS) and grains spike1 (GS), 1000-kernel weight (TW), and grain yield plant^{1} (GY) of 4 triticale genotypes [Karma (G1), Presto (G2), Ayşehanım (G3), and Mehmetbey (G4)] and their 6 F_1 offspring. The mean squares of general combining ability (GCA) and specific combining ability (SCA) were statistically significant for all traits. According to the GCA/SCA, additive gene effects were found for all traits. According to the desired values for traits on …
