Le déclin de la fertilité des sols est répandu dans le Tigré et menace la sécurité alimentaire. La gestion intégrée des nutriments (INM) qui implique l'application combinée d'engrais organiques et inorganiques, aide à surmonter les problèmes associés à l'application unique de l'une ou l'autre source pour améliorer la productivité des cultures. Sur la base de ce fait, une expérience a été menée pour évaluer l'effet de l'application intégrée d'engrais inorganiques et FYM sur l'état de fertilité du sol, les performances agronomiques et socio-économiques du riz. Une expérience factorielle 4x3 composée de quatre niveaux d'engrais inorganiques (0, 25, 50 et 75 kg/ha) et de trois niveaux de FYM (0, 6 et 9 t/ha) a été présentée dans RCB Design avec trois réplications. Les résultats ont révélé que l'application de 9 t/ha FYM avec 75 kg/ha de IF a donné lieu à un rendement en grains de 44,4 Ql/ha (p < 0,05), mais l'analyse de dominance a montré que ce rendement agronomique plus élevé n'a pas généré de profit le plus élevé car la valeur de l'augmentation du rendement n'est pas suffisante pour compenser l'augmentation des coûts. La perception des agriculteurs répondants à l'égard des engrais inorganiques a montré que 76 % des répondants n'étaient pas disposés à utiliser des engrais inorganiques à pleine dose.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The decline in soil fertility is widespread in Tigray and is threatening food security. Integrated Nutrient Management (INM) which implies combined application of organic and inorganic fertilizers, helps to overcome the problems associated with single application of either source for enhanced crop productivity. Based on this fact, an experiment was conducted to evaluate the effect of integrated application of inorganic fertilizers and FYM on soil fertility status, agronomic and socioeconomic performance of rice. A 4x3 factorial experiment consisting of four levels of inorganic fertilizers (0, 25, 50 and 75 kg/ha) and three levels of FYM (0, 6 and 9 t/ha) was laid out in RCB Design with three replications. The results revealed that application of 9t/ha FYM with 75 kg/ha of IF resulted in grain yield of 44.4Ql/ha (p 0.05), but the dominance analysis showed this higher agronomic yield did not brought highest profit because the value of the increase in yield is not enough to compensate for the increase in costs. The perception of the respondent farmers to inorganic fertilizers showed that 76% of the respondents had no willingness to use inorganic fertilizers at full dose. 136 pp. Englisch.
