ALVARADO-CARRILLO, Manuel; DIAZ-FRANCO, Arturo  y  ALEJANDRO-ALLENDE, Florencia. CHICKEN MANURE, ARBUSCULAR MYCORRHIZAL AND CHEMICAL FERTILIZATION REDUCED ON SQUASH AND CUCUMBER PRODUCTIVITY. Rev. Int. Contam. Ambient [online]. 2018, vol.34, n.2, pp.273-279. ISSN 0188-4999.  https://doi.org/10.20937/rica.2018.34.02.08.

Chemical fertilization is one of the higher cost practices, thus reducing the profitability of production; besides, it causes soil pollution and degradation. Biological fertilization is a practice that follows the criteria of sustainable agriculture through the rational management of available resources. The aim of this study was to identify the influence of arbuscular mycorrhiza and chicken manure in combination with half of the chemical fertilizer, on zucchini and cucumber productivity. The treatments were: (1) 100 % conventional chemical fertilization (CF), squash 120N-90P-00K and cucumber 140N-90P-00K; (2) seed inoculation with Rhizophagus intraradices (0.5 kg/ha) + 50 % CF; (3) chicken manure (3 t/ha) + 50 % CF, and (4) absolute control. Estimation of the accumulated fruit yield and an economic analysis of production were also performed. The results indicated that conventional chemical fertilization can be replaced by inoculation with R. intraradices or chicken manure and half of the chemical fertilization. Besides being environmentally friendly, this management matched the profitability of production with respect to chemical fertilization in squash; in cucumber, the highest return was obtained with arbuscular mycorrhiza and half of the chemical fertilization.
