A researh on investigation of the application possibilities of direct drill machine with liquid fertilizer assembly for grain planting stubble

In this study, it is aimed to investigate the application possibilities of a direct sowing machine, which can sow directly without cultivating the soil after the sunflower harvest in the Thrace Region, by applying liquid fertilizer, instead of the granular fertilizer used in the current sowing machines, and applying liquid fertilizer with sowing. The main material of the research is the grain sowing machine for sunflower stubble with liquid fertilizer system produced by Altayoğlu Agricultural Machinery Food Agriculture and Farmer ind. trade. co. ltd. The field work of the directly sowing machine was carried out in the production areas of the company located in neighborhood of Ilyas, Hayrabolu District of Tekirdağ Province, in the 2019-2020 production season. The performance of the direct drill machine was determined from the vegetative and genarative characteristics of the sowed plant, plant wet root weight, plant height, spike length, number of grains per main spike, thousand kernel weight and grain yield. In the results obtained in the research, the effect of liquid fertilizers produced in different types on the wet root weight of the plant was found statistically significant. The highest wet root weight was found in fertilizer B with 7.30 g and the lowest in 4.53 g in the conventional method. The applied liquid fertilizers had no effect on the plant height. The difference was found to be statistically significant in terms of the effect of liquid fertilizers on spike length. Maximum spike length was obtained with 98.83 mm B liquid fertilizer application and at least 82.23 mm with traditional method. The number of grains per main spike was found to be at most 1,90 g in B fertilizer B and at least 1,44 grams in the conventional method. The highest thousand kernel weight was obtained in B liquid application with 41.99 g and the lowest was obtained in C liquid fertilizer application with 41.39 g. The effect of liquid fertilizer applications on yield was statistically insignificant. Among the liquid fertilizers applied in the same dosages, the highest grain yield was 646.91 kg / da in B fertilizer and the lowest grain yield was 593.07 kg / da in the traditional method. Liquid fertilizers applied to the seed bed during the planting of the grain had a positive effect on some vegetative and generative properties of the plant. It was obtained that the effect of yield parameter, which is important in plant production, on liquid fertilizers is not significant.
