The Effect of Different Fertilizer and Dose Applications on Grain Yield and Some Crop Characteristics of Oat (Avena sativa L.)
Abstract
In this study, the effects of different organic fertilizer applications (cattle manure, leonardite and seaweed) on grain yield and some plant characteristics of oat (Avena sativa L.) were investigated. The oat variety 'Kahraman' was utilized in the experiment. The trial was established in Kahramanmaraş Sütçü İmam University, Faculty of Agriculture Research and Application Area in 2020-21 and 2021-22 growing seasons according to the Bi-level Nested Classification Model trial design with 4 replications. Fertilizer doses were applied as leonardite 50, 100, 150, 200 and 250 kg da-1, cattle manure 1000, 1500, 2000, 2500 and 3000 kg da-1, seaweed 30, 40, 50, 60 and 70 g da-1 and chemical fertilizer pure nitrogen 5, 10, 15, 20 and 25 kg da-1. According to the 2-year average results of the study, it was determined that the differences between the treatments were statistically significant in the traits examined except ripening time, biological yield and harvest index. Grain yield varied between 264.13416.29 kg da-1 in the first year, 212.48-449.17 kg da-1 in the second year and the average of the years varied between 238.31-420.73 kg da-1. In the study, the highest grain yield was observed in the first year in chemical fertilizer (CF-3) application, while in the second year and the average of the years, it was obtained in cattle manure (CM-5). It has been determined that cattle manure reached the highest value in terms of grain yield (3000 kg da-1) and seaweed in terms of upper internode length (40 g da-1). It has been observed Cattle manure was found to be superior to chemical fertilizer and other organic fertilizer forms. In this study, it was concluded that cattle manure (3000 kg da-1) dose was the most suitable dose for oat cultivation in Kahramanmaraş ecological conditions.
