Abstract:

This study was conducted in 2014 and 2015, in order to determine the impact of various organic and microbial fertilizer applications on productivity and productivity elements in some cotton varieties, in the Organic Farming Conditions in Harran Ovas. The study applied organic farming fertilizer (2000 kg ha-1), pig fertilizer (1000 kg ha-1) and microbial fertilizer (100 cc 100 lt water). In the study, ST-468, BA-119 and Candia cotton varieties were used as plant material. The trial was performed four times according to the trial pattern of divided parcels. The study examined the criteria of plant length(cm), wood branch (fruit plant-1), fruit branch (fruit plant-1), the number of cows per plant (fruit plant-1) and mass cotton production (kg ha-1). According to the results of the variance analysis obtained in the study, the mass cotton productivity of varieties in 2014 varied between 3313.8 kg ha-1 (ST-468) and 3490.7 kg ha-1 (Candia), and the highest mass cotton productivity was obtained from the Candia variety. In 2015, the mass cotton output of the varieties varied between 4389.0 kg ha-1 (Candia) and 4705.7 kg ha-1 (BA-119), with the highest output from the BA-119 varieties. As a result of organic and microbial fertilizer applications, in 2014, the mass cotton production varied between 1879.6 kg ha-1 (control) and 4346.0 kg ha-1 (Biofarm fertilizer), the highest efficiency was achieved from the application of Biofarm fertilizer. In 2015 it was 3661.1 kg ha-1 (Control) with 5231. It has been determined that the highest yield varies between 5 kg ha-1 (puppy fertilizer + microbial fertilizer), the highest yield is obtained from the application of puppy fertilizer + microbial fertilizer. In particular, microbial fertilizer has a significant impact on the efficiency and efficiency components. Our study has concluded that the interaction of pig fertilizer + microbial fertilizer with the BA-119 variety provides the highest efficiency.
