The effects of humic acid on nutrient status yield and quality of tomato
In order to increase organic matter content of soil, humic acid application is the most economic and fast method. In this study, the effects of humic acid and their dosages (0, 4, 8, 12, 16 and 20 l da-1) on nutritional, status of tomato and yield-quality were investigated. During the growing period...

Summary: | In order to increase organic matter content of soil, humic acid application is the most economic and fast method. In this study, the effects of humic acid and their dosages (0, 4, 8, 12, 16 and 20 l da-1) on nutritional, status of tomato and yield-quality were investigated. During the growing period, a dose of NPK was applied through drip irrigation. The experiment was carried out according to randomized complete block design with four replications under greenhouse conditions in 2011-2013 autumn tomato growing season. In order to determine effects of humic acid, plant and leaves fruit were analyzed during the experiment. The results of analysis showed that increases of N, P, K, Fe, Cu content of tomato leaves was found important whereas Ca, Mg, Mn, Zn and B content was not important statistically. The effect of humic acid+NPK applications on fruit quality of tomato was positive. Fruit yield was increased by humic acid applications compared to control.
Tarımsal üretimde organik madde sorununun en ekonomik ve hızlı çözüm yollarından biri topraÄa hümik asit uygulanmasıdır. Hümik asitler toprakta zamanla ayrıÅarak bitkilere yarayıÅlı hale gelmektedir. Bu çalıÅma ile farklı dozlarda (0, 4, 8, 12, 16 ve 20 l da-1) uygulanan hümik asidin domates bitkisinin beslenme durumu, verim ve kalitesi üzerine etkileri araÅtırılmıÅtır. YetiÅtiricilik sezonu boyunca her sulamada tek doz NPK uygulanmıÅtır. Deneme sera koÅullarında 2011-2013 sonbahar domates yetiÅtirme döneminde tesadüf blokları deneme desenine göre dört tekerrürlü olarak yürütülmüÅtür. Hümik asit+NPK uygulamalarının etkilerini belirlemek amacıyla yaprak ve meyve örnekleri alınarak analiz edilmiÅtir. Analiz sonuçlarına göre domates bitkisinin N, P, K, Fe ve Cu içeriklerindeki artıŠistatistiksel olarak önemli bulunurken Mg, Ca, Mn, Zn ve B içeriklerindeki artıŠönemli bulunmamıÅtır. Hümik asit+NPK uygulamaları meyve kalite kriterlerini olumlu etkilerken, parsellerin verim deÄerlerini de kontrole göre artırmıÅtır. |
