Abstract
The objective was to study the growth of the area of melon subjected to the effects of irrigation frequency and water drip. In Irrigation District Baixo Acaraú, set up an experiment using the experimental design in randomized blocks with 20 treatments and 3 blocks in a factorial 4 x 3. The treatments resulting from the combination of 5 irrigation levels (L1 = 60%, L2 = 80%, 100% = L3, L4 and L5 = 120% = 140% of ETc) and 4 rates of application of water (F1 = a blade split in 3 times a day, F2 = the blade split in 2 times a day, F3 = applied to the blade once a day, and F4 = a slide in once on alternate days). The amount of water applied was determined by the need for replacement of losses of crop evapotranspiration by tank Class A. It was found that the factors blades and irrigation frequency characteristic were indifferent to the number of sheets; blade made variable effect on leaf area only to DAS 41; blade made variable effect on leaf area only to DAS 41; Most matter production dried melon is conditioned by the higher irrigation, the largest and the smallest increment of dry matter during the growth phase, were obtained with the blades of 266.19 and 159.41 mm, corresponding to 94.36 and 83.20 %, the increase in daily dry matter intake increased proportionally to the applied irrigation depth up to 41 days after sowing.
