Productive performance of watermelon (Citrullus lanatus) under the effect of different irrigation depths, in Santa Elena, Ecuador. RCTU [online]. 2018, vol.5, n.2, pp.6-9.

The research was conducted in Manglaralto and Colonche, in the northern part of the province of Santa Elena, under the direction of the CIAP-UPSE agricultural research center. The aim of the research was to assess the productive performance of watermelon hybrid Royal Charleston, under different sheets of irrigation in two localities of the peninsula of Santa Elena. The treatments were five irrigation depths, 40, 60, 80, 100 and 120% of the crop evapotranspiration, the statistical design used was randomized complete blocks the treatment means were compared using Tukey 5% probability of error statistical, evaporation is mediated in the tub of evaporation class A, variants of irrigation influenced all of the variables evaluated, generating a progressive increase of production according to the treatments, the crop evapotranspiration was 218 mm in Manglaralto and 377 in spring of Colonche, better treatment is for 120% etc. with 109 tonnes per hectare in Manglaralto, however, in spring of Colonche production decreased to 75,13 tons per hectare with the same level of irrigation.
