Treatments consisted of a factorial combination of the use or non use of green manures with five doses of N (0.40, 80, 120 and 160 kg.ha -1 ), arranged in the field according to a split plot design and five replicates. Results showed positive responses of potato to N application, green manure incorporation and the integration of both alternatives. The response magnitude to the application of several doses of N depended on the use or non use of green manure. In this sense, in 1992-1993, with the use of canavalia, maximum yields of 33 t.ha -1 were recorded by only applying 53 kg.ha -1 N (32 % of the maximum dose); in 1994-1995, on the other hand, maximum yields (29 t.ha -1 ) were reached when applying 67 kg.ha -1 N (50 % of the maximum dose) and the use of canavalia. By using green manure alone, potato yields were equivalent to 80 kg.ha -1 N. Without green manures the response to nitrogen fertilization was lineal, optimum yields (34.8 t.ha -1 ) being in 1992-1993 with the application of 160 kg.ha -1 N, these being of 130 kg.ha -1 in 1994-1995. 2000 artículo científico 1819-4087 https://www.redalyc.org/articulo.oa?id=193232232002 es http://www.redalyc.org/revista.oa?id=1932 Cultivos Tropicales application/pdf Instituto Nacional de Ciencias Agrícolas Cultivos Tropicales (Cuba) Num.1 Vol.21 |
