The Effect of Fertilization with N-P-K in Yield of Natural Pasture Grazed by Sheep on Southern Italy
Publication Date
1985
Location
Kyoto Japan
Description
In order to raise the very low pasture yield in the dry regions of Southern Italy, a research was undertaken on the efficiency of mineral fertilization, owing to the variability of climatic conditions. Two levels of N (0-50 Kg ha-1), P (0-100 Kg ha-1) and K (0-100 Kg ha-1) arranged in factorial combinations were compared with a pasture grazed by sheep in a hilly area of Basilicata region (550 m s.l.} since 1982. During the spring of the first two years rainfalls amounted respectively to 79 mm and 146 mm while maximum temperature reached 30°C and 22°C in May, therefore only one grazing was obtained in 1983 and two were practiced in 1984. The D M utilized by sheep was higher in fertilized plots with both separate elements and especially with a combination of them: the highest yield was obtained by adding NPK; among separate elements the best results were achieved with P. Fertilization effects were more evident as increase Milk-FU and as a result there was an increased number of days per sheep. Finally fertilization caused a decrease in no-fodder species.
