Estudo comparativo entre sistemas de irrigação por sulcos e gotejamento na cultura do pimentão.

Abstract

In a trial carried out in Ponte Nova 'Município' (MG­Brazil) the effects of irrigation Systems through furrow anã drip technique was studied on green pepper(Capsicum annuun L. ), 'aas cadura Ikeda Cultivar' mature fruit and seeds, using he same quantity of water and the same irrigation frequency. The irrigation was through a daily 4mm water blade with a 3 day irrigation frequency. The trial was carried out in 'Podzólico Vermelho Amarelo Cãmbico' Soil,in the year 1977. The arop was planted with a Im spacing between Rows and 0,4nv among plants. Manuring was through 50g of the formula 6­14­8 (N+P+K) + lg magnesium sul phate per plant, and 3 manures per covering, consisting of 2Gg of the mixture per plant every of 3 0 ™ dag. The harvests numbe ring 14, were done weekly, the first of them on the thirtieth of june, 1977. Through the results obtained, it was observed that the irrigation by drips and furrow had reaohed equal effect considering the normal fruit production, the percentagem of dry materzal in the pulp, the incidence of defective fruit, the seed production and germinative energy, when the same amount of water was applied inside the same watering tum. The Systems disphayed a diffèrente behavior for the fruit médium weigh being on at up to the first half of the harvest, the furrow was superior to the drip Systems, the reserve occuring in the following harvests The studied characteristics varied during the time of harvest, showing a decrease in fruit size and germinative energy in aacordance with the time passed from the first harvest. The percentage of dry material in the pulp was more important in the fruits picked up during the first half ot the to tal harvest time, being the contrary for fruit and seed production.
