Effect of nutrient supply and site characteristics on NPK yield of different maize hybrids
2000
Debreczeni,K. | Berecz,K.
The rich assortment of maize cultivars available in Hungary as the result of genetic research can be recommended to crop growers in the full knowledge of their responses to nutritional effects in the given agro-ecological region.The nutrient responses of eight different maize (Zea mays L.)hybrids differing in the duration of the vegetation period (FAO 200-430) were studied in field fertilisation trials conducted in four different agro-ecological regions of Hungary.Four treatments were applied:1.minimum NPK dose, 2.NPK dose corresponding to the nutrient requirements of maize, 3.NPK dose exceeding the nutrient requirements of maize, 4.farmyard manure (FYM).The NPK contents of the grains were measured in addition to the grain yields.
