Irrigation depths and fertilizing forms in table tomato production

Abstract

The determination of the correct irrigation depth for the production of tomato fruits is crucial for obtaining higher yields and higher quality fruit. The objective of this study was to evaluate the development and productivity of hybrid table tomato Natalia under different irrigation drip and two fertilization. The experiment was conducted from April to September 2013 Jataí -GO. The experimental designwas randomized blocks in a factorial arrangement 4 x 2, referring to four irrigation levels (66, 100, 133, 166%) the daily location of the reference evapotranspiration (ETo), calculated daily by the Penman -Monteith and two fertilization, which was held by fertigation and conventional fertilization, with 4 repetitions. The variables analyzed were plant height and stem diameter at 30, 45, 60 and 80 days after transplanting, total, commercial and non-commercial. The results showed that the stem diameter wasnot affected by differentiation of blades and types of fertilization. The fertigation provided increased business productivity compared to conventional fertilization when the corresponding slide to 66% of ETo and increase in plant height with the depth of100% of ETo was applied. The depth of 100% of Eto provided greater plant growth, increase in total and commercial yield of tomato.
