The Effect of Different Nitrogen Dosages on Some Yield and Quality Properties of the Cucumber Grown with in Nutrient Film Technique

Journal Title: Journal of Experimental Agriculture International - Year 2016, Vol 13, Issue 2

Abstract

Aim: The effect of 4 different nitrogen dosages (7, 10, 13 & 16 mM) on the Plant Height, Dry Matter Yield, Number of Fruit per Plant, Fruit Yield per Plant, and Total Nitrogen Concentration of the Spring S1, which is one of the parthenocarpic hybrid cucumber types grown in Nutrient Film Technique (NFT), has been examined in this study. Study Design: Four different nitrogen dosages (N7, N10, N13 and N16 mM) were prepared according to the Randomized Block Design with 3 replications. In evaluating the study results, the Minitab 14 statistical package program was used, and the variance analysis Fig was prepared thus making it possible to determine the significance level of the subjects. According to the p<0.05 probability value, the Low Significant Difference Values(LSD) were determined, Place and Duration of Study: This research, Uludag University Vocational School of Technical Sciences, Parks and Horticulture Application was carried out in greenhouses Methodology: The plants were germinated in egg-trays, and after they had 3 leaves they were transferred to NFT Units with 12 compartments in which 16 plants were grown and which had the size of 105 cm x 91 cm x 47 cm with 4 pieces of 155 mm x 70 mm growth channel. The Plant Height, Dry Matter Yield (root, body and leaves), Fruit Yield, and Total Nitrogen Amount (root, body and leaves) were analyzed in the study. Plant Height, Dry matter yield and total nitrogen content the plant samples were taken out (collected) with their roots on the 21st, 42nd, and 63rd days after planting. Number of fruit per plant and Fruit yield per plant the plant samples were taken out with their roots on the 42nd, 52nd, 63rd days after planting. Results: According to the results obtained in the study, the values of the examined characteristics increased until the N13 dosage of the nitrogen; and started to decrease in the N16 dosage, which is the next dosage. While the effect of the nitrogen dosages on the nitrogen concentrations in the roots was not considered as being statistically significant, it was considered as being significant in the stem and leaves. Conclusion: Generally, it may be suggested that especially the N16 dosage affects the plant negatively in the examined characteristics, and that it almost starts hazardous effect in this dosage.
