During the years 2001-2002 two field experiments with microirrigation of summer squash ‘Miranda’ on the sandy soil were carried out in Kruszyn Krajenski near Bydgoszcz. The experiments were conducted in a randomized blocks method of a one-factorial system with four replications. The investigated factor was microirrigation used in three variants: W1 - non-irrigated plots (control), W2 - drip-irrigated plots, and W3 - micro-sprinkler irrigated plots. Microirrigation significantly increased the mean marketable yield of fruits and seeds in comparison with control plots. Also a significant effect of irrigation was detected in the case of the fruit weight. Both irrigation methods used decreased NO3 content in fruits and on the other hand increased dry matter, vitamin C and β-carotene. Calculated water use efficiency was higher for drip irrigation.
