Efectos del abono orgánico sobre la fijación simbiótica del nitrógeno en la soya glycine max l. variedad iniap 306

Abstract:

This investigation sought to define the benefits that contribute the organic payments in the soya cultivation, to try to substitute the chemical products that are harmful and to maintain this way the natural reservations. The proposed objectives were the following ones. To evaluate the effect of the different types of organic payments, in the population of nodules and in the weight of the same ones. To evaluate the effect of the association of organic payments more the Rhyzobium japonicum in the formation of dry matter. To determine the yield and the economic evaluation of the soya. The variety INIAP was used 306, the treatments were ordered in the field, following the design of blocks at random with three repetitions and 6 treatments making a total of 18 experimental units each one of 15.20 m2. The treatments were the following organic payments: 1. witness without fertilizer, 2. Compost (7.5 tn/ha), 3. Vitagrés (10 l/ha), 4. Biol (2000 l/ha), 5. Bokashi (5.4 tn/ha), and the 6. Humus(2 tn/ha). The variables that were evaluated were the following ones: Number of nodules for plant; Weight of nodules; Mensuration of nodules; Quantity of dry matter; Yield in kg/ha. The results by means of they didn't have significant statistical differences in none of the study factors. The best yield obtained it the Biol with 2178 kg/ha, followed by the Bokashi with 1837 kg/ha, the Compost with 1761 kg/ha and the Humus with 1629 kg/ha. On the other hand that the Witness obtained the smallest yield with 1477 kg/ha, but in weight and number of nodules the witness obtained the biggest average with 0.77 g. and 86.90 nodules for plant respectively. The biggest profitability obtained it the treatments Biol 2000 l/ha with 740.38 USD and Bokashi 5.4 tn/ha with 624.46 USD.
