Agronomical and technological performances of some early cotton cultivars planted as second crop in Diyarbakir condition, Turkey

Abstract

The opportunity to increase agricultural areas is limited, so that increasing demands can be achieved by producing more products from existent agricultural areas. Second cropping is a sustainable practice in which more than one crop is grown consecutive on the same ground. This study was carried out to determine agricultural and technological properties of growing cotton (Gossypium hirsutum L.) as second crop on stubble of ridge planted wheat in Diyarbakır. The experiment was conducted in the experimental area of Dicle University Agricultural Faculty as randomize complete block design with three replications. Eight cotton varieties (Berke, Lachata, BA 119, STV 468, STV 373, Özbek 100, Fantom and DP 396) were used as material. Wheat, planting on ridge, was harvested approximately 10 cm above the soil surface June 12, 2012. Straws of harvested wheat were removed from the experimental area. Same day cotton varieties were planted two rows on each ridge. The results indicated that STV 468, Fantom and Berke in terms of seed cotton yield; Fantom, Berke in terms of fiber length; DP 396 and Berke interms of fiber strength had given the highest values. However, our study suggested that whether very earlier cotton varieties (Özbek 100, Berke and Fantom) are grown, cotton will be grown as second crop after ridge planted wheat in the stubble seedling under Diyarbakır ecological condition.
