Resumo: | The high rate of evaporation and the limitation of water, in quantity and quality, require the search for strategies that enable the sustainability of agriculture in the world. The experiment was carried out to evaluate the effects of water salinity, lateral protection of the pits and calcium doses on the production components of passion fruit cv. BRS GA1. The treatments were arranged in a 2 x (2 x 5) split plot, corresponding to water salinity (0.3 and 4.0 dS m-1) in the main plot, and combinations between lateral protection of the pits (without and with) and calcium doses (0, 30, 60, 90 and 120 kg ha-1) in the subplots. Number of productive branches, indices of early ripening and concentrated cropping, calculated from the weekly yields, number of fruits per plant, average fruit weight and yield were evaluated. The increase in electrical conductivity of irrigation water delays harvest and reduces the number of fruits per plant, fruit weight and yield of passion fruit. The lateral protection of the pits did not have a positive effect on the cultivation of passion fruit irrigated with saline water. Calcium dose of 60 kg ha-1 in the Entisol with low content of this macronutrient attenuates the effects of irrigation with saline water, increasing the yield of yellow passion fruit. |

A elevada taxa de evaporação e a limitação de água, em quantidade e qualidade, requerem a busca de estratégias que viabilizem a sustentabilidade da atividade agrícola no mundo. O experimento foi desenvolvido para avaliar os efeitos da salinidade da água, da proteção lateral das covas e doses de cálcio nos componentes de produção do maracujazeiro-amarelo cv. BRS GA1. Os tratamentos foram arranjados em parcela subdividida no esquema 2 x (2 x 5) correspondente a salinidade da água (0,3 e 4,0 dS m-1), parcela principal, e as subparcelas às combinações entre proteção lateral das covas (sem e com) e doses de cálcio (0, 30, 60, 90 e 120 kg ha-1). Foram avaliados o número de ramos produtivos, índices de amadurecimento precoce e de cultivo concentrado, número de frutos por planta, massa média de frutos e produtividade. O aumento da condutividade elétrica da água de irrigação retarda a colheita e reduz o número de frutos por planta, a massa dos frutos e a produtividade do maracujazeiro. A proteção lateral das covas não exerceu efeitos positivos no cultivo de maracujazeiro irrigado com água salina. A dose de 60 kg ha-1 de cálcio em Neossolo Regolítico com baixo teor deste macronutriente atenua os efeitos da irrigação com água salina, aumentando a produtividade do maracujazeiro-amarelo.
