The Effects Of Organic and Conventional Farming Systems on Fibres Quality Properties of Some Cotton(Gossypium hirsutum L.) Varieties Under Semi Arid Climatic Conditions of Turkey and Correlations Between Fibre Quality Properties
Abstract
Objective: The aim of the present research was to compared differences among the organic and conventional farming system in fibres quality properties of some cotton varieties under semi arid climatic conditions of Turkey.
Material and Methods: This research was carried out by using the ST-468 and BA-119 cotton varieties in three replications, according to the randomized block split parcel trial design under organic farmland conditions in 2013-2014 growing seasons; NPK, Biofarm (cattle fertilizer) and pigeon manure and control plots (without fertilizer).
Results: It was found that the seed cotton yield varied from 3594.8 (ST-468) to 3737.4 kg ha-1 (BA-119) in the varieties and the highest yield was obtained from the BA-119 with 3737.4 kg ha-1. It was determined that there was a statistical important difference between two varieties in terms of seed cotton yield. We think that this efficiency difference between varieties is caused by genetic and environmental factors. The result of fertilization applications was changed between 3370.0 (cattle manure) and 4424.5 kg ha-1 (chemical fertilization) and the highest seed cotton yield was obtained from chemical (NPK) fertilization applies.
Conclusion: According to the results of the study, it has been concluded that the cotton produced in the conventional production conditions is heavily contaminated with chemical inputs and this has negative effects on the pollution of the environment.
