Bu araştırmada, Hatay ili Reyhanlı ilçesinde ana ürün olarak yetiştirilen patates (Solanum tuberosum L.) bitkisinde, organik ve mineral gübre uygulamalarının, verim ve bazı toprak mikrobiyal aktivitelere etkilerinin belirlenmesi amaçlanmıştır. Çalışma, 2019-2020 yıllarında tesadüf bloklarında bölünmüş parseller deneme desenine göre üç yinelemeli olarak yürütülmüştür. Ana parsellerde çeşitler (Madeleine-Ç1, Melody-Ç2), alt parsellerde ise gübre uygulamaları (mineral gübre (MG1; MG2), ahır gübresi (AG1; AG2), solucan gübresi (SG1; SG2), Kompoze organik (AG1; SG1) ve organo-mineral (MG/2ÇG1; MG/2SG1)) yer almıştır. Çalışmada parsellerin yumru verimi, toprak solunumu (CO2 üretimi), dehidrogenaz enzim aktivitesi (DHA) ve mikrobiyal biyomas karbon (MBC) içerikleri belirlenmiştir. Araştırma sonuçlarına göre en yüksek verim değerleri Madeleine çeşidinde kompoze organik gübre uygulamasından (AG1SG1) 5701 kg da-1 olarak elde edilmiştir. CO2 aktivitesi 9,3-17,3 μg gkt-1 aralığında değişim gösterirken en yüksek Madeleine çeşidinde AG2 uygulamasından elde edilmiştir. DHA değerleri 152,7-675,2 μg TPF gkt-1 aralığında değişim gösterirken en yüksek Melody çeşidinde AG2 uygulamasında belirlenmiştir. MBC değerleri 64,2-222,6 μg gkt-1 en yüksek Melody çeşidinde AG2 uygulamasında belirlenmiştir. CO2 ve DHA aktivitesi çeşit farklılığında istatistiki olarak etkilenmezken yumru verimi ve MBC aktivitesi etkilendiği belirlenmiştir. Araştırma sonuçlarına göre organik ve organo-mineral uygulamaların incelenen parametreler üzerinde istatistiki açıdan önemli (p<0,05) artışlara neden olduğu tespit edilmiştir.
In this study, the target is to determine the effects of organic and mineral fertilizer applications, productivity and some soil microbial activities in the potatoes (Solanum tuberosum L.) grown as the main product in the Hatay or Reyhanlı district. The study was carried out three times by trial pattern of parsels divided into random blocks in the years 2019-2020. The main parsels included varieties (Madeleine-C1, Melody-C2), and the subparsels included fertilizer applications (mineral fertilizer (MG1; MG2), grain fertilizer (AG1; AG2), insect fertilizer (SG1; SG2), Composite organic (AG1; SG1) and organo-mineral (MG/2CG1; MG/2SG1)). The study determined the pot production, soil inhalation (CO2 production), dehydrogenase enzyme activity (DHA) and microbial biomass carbon (MBC) content. According to the research results, the highest efficiency values were obtained from the application of composite organic fertilizer (AG1SG1) in the Madeleine variety as 5701 kg and 1. The CO2 activity varies in the range of 9.3-17.3 μg gkt-1, while the highest is derived from the application of AG2 in the Madeleine variety. The DHA values are varied in the range of 152.7-675.2 μg TPF gkt-1, while the highest in the Melody variety is determined in the application of AG2. The MBC values are 64,2-222,6 μg gkt-1 in the highest Melody variety in the AG2 application. CO2 and DHA activity are not statistically influenced in the variety of varieties, while it has been determined that the yield and MBC activity are affected. According to the research results, organic and organo-mineral applications have been found to cause statistically significant (p<0,05) increase in the parameters studied.
This research was carried out to determine the effects of organic and mineral fertilizer applications on yield and some soil microbial activities in two potato (Solanum tuberosum L.) varierities (Madeleine and Melody). In this research, two potato varieties were cultivated in Reyhanlı (Hatay) field conditions during 2019-2020. The field trials were design as randomized block design split plots with three replicates. Varieties were in main plots while fertilizers were in sub-plots. Fertilizer apllications were mineral fertilizer (MG1; MG2), barn manure (AG1; AG2), worm manure (SG1; SG2), compozed organic (AG1; SG1) and organo-mineral (MG / 2ÇG1; MG / 2SG1). In the study, tuber yield (kg da-1), soil respiration (CO2 production), dehydrogenase enzyme activity (DHA) and microbial biomass carbon (MBC) contents were determined. The highest yield values were obtained from the compozed organic fertilizer application (AG1SG1) as 5701 kg da-1 in the Madeleine variety. CO2 activities varied between 9,3-17,3 μg gkt-1, while the highest result was obtained from AG2 application in Madeleine variety. DHA values varied between 152,7-675,2 μg TPF gkt-1, the highest result was determined in AG2 application in Melody variety. MBC values were ranged between 64,2-222,6 μg gkt-1, the highest result were obtained in the AG2 application in the Melody variety. The results showed that CO2 and DHA activity were not statistically affected by variation, however tuber yield and MBC activity were found affected by the varieties. According to the results of the research, it was determined that organic and organo-mineral applications caused statistically significant (p <0,05) increases on the parameters examined.
