Abstract
In experiments carried out in the years 1997–2000 the influence of irrigation, cultivation technology and nitrogen fertilization on yield and economic effects of potato cultivation was evaluated. With the increase in nitrogen fertilization up to 120 kg/ha, the tuber yields increased both in irrigated and non-irrigated field, but in the former one the increase was significantly greater. Irrigation, on the average for remaining factors, increased yield by 19.8%. The best effects both in irrigated and non-irrigated field, at average nitrogen fertilization, were obtained with the high-input technology. Irrigation resulted in the increase in the direct surplus by c. 1967 PLN/ha (with no calculation of the treatment cost).
