Effects of different fertilizer applications on yield, yield components and fiber quality in cotton (Gossypium hirsutum L.)
Harran Tarım ve Gıda Bilimleri Dergisi(2022)
Abstract
In this study, Candia variety was used according to the randomized block plots experimental design in Şanlıurfa-Harran conditions in 2020-2021 and was carried out with 3 replications. Each parcel consisted of 5 rows, the parcel length was 12 m, the row spacing was 70 cm, and the row spacing was 10-12 cm. The experiment consisted of a total of 24 plots. In the study, applications consisting of mixtures of different chemical and organic fertilizers were applied. These are 1-Control, 2-Base fertilizer (0 kg)+Top fertilizer (Urea 35 kg da-1), 3-Base fertilizer (10 kg DAP da-1)+Top fertilizer (Urea 35 kg da-1), 4-Base fertilizer (20 kg DAP da-1)+Top fertilizer (Urea 35 kg da-1), 5-Base fertilizer (30 kg DAP da-1) )+Top fertilizer (Urea 35 kg da-1), 6-Base manure (2 tons farm fertilizer da-1)+ Top fertilizer (Urea 35 kg da-1), 7-Base manure (4 tons farm fertilizer da-1)+Top manure (Urea 35 kg da-1), 8-Base manure (6 tons farm fertilizer da-1)+Top fertilizer (Urea 35 kg da-1) consisted of subjects. In post-harvest measurements, yield per decare (kg da-1), number of bolls (piece plant-1), boll weight (g), boll seed weight (g), ginning outturn (%), 100 seed weight, fiber fineness (mic.), fiber strength (g tex-1) and fiber length (mm) were investigated. According to the results obtained from the study; the highest number of cocoons in both years of the experiment (24.33 and 24.66 per plant); boll weight (6.66 and 6.55 g); The yield per decare (526.40 and 514.66 kg da-1) was obtained from the application of 6 tons of farm manure + 35 kg of urea. It has been determined that the applications that are the subject of the study have no effect on the fiber quality properties.
