مقایسه روشهای آبیاری برعملکرد گوجه فرنگی رقم چیف تحت تاثیر تیمارهای مختلف کودی در منطقة جیرفت

One of the problems of farmers in irrigation management is of Jiroft and Kohnuj. Practical and scientific solutions to improve water use efficiency of tomato in plastic cover that is one of the region's culture, it seems essential. In order to study the best ways to improve efficiency and productivity of water use in a factorial experiment in a randomized complete block design with three replications. The first factor in this experiment consists of a stack of two atmospheric surface irrigation, drip (The method of drip irrigation tape into the atmosphere away from the foot of the plants were 15 to 20 cm.) The second factor is irrigation, respectively 50%, 75% and 100% of the water requirements of tomato plants. Traits in this project include a) the characteristics of the vegetative (plant fresh weight - dry weight - root fresh weight - dry weight of roots). B) Reproductive characteristics ( number of flowers per plant - fruit of the plant - the largest fruit weight - dry fruits - the fiction market - the non- fiction market - the total ). C) Qualitative characteristics (percent juice - soluble - pH juice - vitamin C). D) Absorption of nutrients K-Mg-Ca-
Na. Method of irrigation amount on growth characteristics and quality characteristics have a significant effect. But vitamin C is significant at 1% which is low vitamin C levels of irrigation water has increased. The reproductive performance characteristics have not been significant, but the yield of non- market -friendly drip irrigation method was 12% lower compared to the furrow is significant. On the number of fruit and nut number of flower there is a significant difference of about 1%. The weight of the largest fruit weight in irrigation Faroe 2 percent higher. Solute Percentage irrigation methods did not affect the absorption of nutrients. The performance comparison showed that the lowest 50% of surface irrigation water requirements of plants and the highest yield of drip irrigation with 100 % water requirement of tomato. The most suitable method for the recommended amount of irrigation water to farmers in the region without using a drop of 100 % of a tomato is required.
