Interaction effect of amount of irrigation water and levels of applied nitrogen on tomato yield and quality using drip irrigation
Journal Title: International Journal of Farming and Allied Sciences - Year 2018, Vol 7, Issue 4
Abstract
In the current study, in order to application of nitrogen with appropriate management water in pressurized irrigation system to obtaining desired function was investigated. Also, the costs and environmental pollution in tomato tillage test as random splits was studied. The results showed that the main factor from water volume based on need water was determined in three surface 75%, 100% and 125%, and also the absolute factor of nutritional element from nitrogen as purify nitrogen was measured in four surface 0, 75, 150 and 225 kg in per hectare. This evaporates and potential were used to determine the irrigation coefficient and efficient rainfall. The potential evapotranspiration, precipitation and efficient irrigating coefficient was used to determine the need for irrigation. Also the Hager’s method was used to account for evaporation and potential transpiration. Plant response include product performance and some fruit quality characteristics such as TSS, Vitamin C and pH as well as water use efficiency by using Danken analysis. According to results of this study, the effect of each factor on the surface of the water level irrigation and nitrogen N on yield and water use efficiency is another factor influenced. Also, increasing the amount of vitamin C in fruits due to an increase in surface irrigation and other results in low levels of the nitrogen. Sea-level rise at low nitrogen levels led to a reduction in water use efficiency, but it is N, T meaningful to reduce water use efficiency in the high level of increase nitrogen levels were increased nitrogen.The amount chlorophyll, the density of nitrogen in level of and the concentration of nitrate the fruits increase density and reduce nitrate in the soil due to increased levels of nitrogen will call attention to increased levels of irrigation water from other plants. Also, increasing the amount of vitamin C in fruits reached due to an increase in surface irrigation and other results in low levels of the nitrogen.
