Effect of different fertilizer application methods during the formation period of vines, cv. Cinsault, at Cauquenes, Chile

Arturo Lavín A.1

A trial was conducted at the Cauquenes Experiment Station (INIA) to measure the influence of diffe rent methods of applying N, P and K fertilizers on growth, yield and nutrition of young vines, cv. Cm sault. Growth and yield data indicated best results for the fertilizer pike application method, followed closely by furrows at both sides. The application in circular bands was less effective, and putting all the fertilizer in the planting hole, practically, did not show any difference with the test plots, with no P or K. Tissue analysis showed an increase of P and K with alI the methods of applying the fertilizers; never theless, all samples, including the test plots (with no P and K), were aboye the level considered critical for vines in fuil production and in the full bloom period. The concentration of N was not influenced, in general, by the fertilizer treatments.
