Eficiência de irrigação em sulco com redução da vazão inicial
Palavras-chave:
irrigação em sulco, eficiência de distribuição, vazão inicial reduzida, umidade do solo, avanço de fluxoResumo
The objective of this study was to determine the efficiency of furrow irrigation with constant and cut-back flow rates. Flow rates of 0.4, 0.61, 0.88 and 1.22 1/sec. were used under and with cut-back flow to 0.4 I/sec.
