Abstract
The influence of irrigation method on nutrient content of potato leaves throughout the season was assessed during three years. Low gallonage “mist” irrigation (M), furrow irrigation (F), mist plus furrow (MF), and no irrigation (NI) were compared. Leaf blades and petioles from Kennebec (1967, 1968, 1969) and Irish Cobbler (1968, 1969) plants were analyzed for P, K, Ca, Mg, Fe, Zn, Mo, Mn, Cu, B and N. Levels of Mo, Mn, Cu and B did not differ either between treatments or during the season. Leaves from different irrigation methods did not differ consistently in levels of N, K, Mg, Ca or Fe. However, during the latter part of two seasons NI plants contained less P and K and more Fe than M or MF plants. F plants were similar to NI plants in nutrient content except that P was lower in the latter. No matter what the irrigation method, N declined as plants matured. Irrigation treatment did not influence the K or Fe levels of petioles consistently. On several sampling dates MF plants were intermediate. Leaves and petioles of M and MF plants consistently contained more Zn throughout all three seasons than non-irrigated or furrow irrigated plants and, in conctrast to the latter, Zn content did not decline as plants matured.
