Na Tunísia, a cultura de cereais representa a atividade agrícola mais importante, tanto pelo número de agricultores como pelo seu papel motor na economia nacional. No entanto, as regiões do centro-oeste da Tunísia sofrem com a irregularidade das precipitações; essa irregularidade e a fraca quantidade de precipitação podem provocar, em certos anos de défice, quedas significativas nos rendimentos e, consequentemente, na produção. O problema da seca, a diminuição do nível do lençol freático, a baixa pressão da água e a preocupação em atenuar o défice hídrico levaram os agricultores que se dedicam à horticultura a utilizar técnicas de rega economizadoras de água , como a irrigação gota a gota. O presente trabalho teve como objetivo estudar o efeito do espaçamento entre as plantas na eficiência da utilização da água e da fertilização azotada, bem como no rendimento do trigo duro (variedade Khiar) cultivado sob irrigação localizada nas regiões semiáridas da Tunísia.
