Reattività alla concimazione azotata di un ecotipo diLolium Rigidumisolato dalla flora spontanea della Sardegna / Bullitta, Pietro; Spanu, Antonino. - In: STUDI SASSARESI. SEZIONE 3: ANNALI DELLA FACOLTÀ DI AGRARIA DELL'UNIVERSITÀ DI SASSARI. - ISSN 0562-2662. - 25:(1977), pp. 69-80.
Abstract:
In the biennium 1974-76 a fertilization trial was carried out on Sardinian
calcareous sons, by utilizing incresing (from o to 450 Kg/ha) N doses, so
as to test the productive capacity of a self-seeding annual ryegrass isolated
from the spontaneous flora of Sardinia.
The results achieved in the biennium show the involved lolium to highly
react to N supplies.
The highest yields are achieved with the highest N doses, with production
peaks over 600 q/ha of grass and 100 q/ha of dry matter. Still from an economie
point of view, on the base of the results attained in the biennium,
N dose from 150 to 200 Kg/ha seem to be the most economical.
