| Abstract | ALVES, Estenio Moreira, M.Sc., Universidade Federal de Viçosa, February 2014. Production of sweet corn and grains intercropped with legumes in no-till organic systems. Advisor: João Carlos Cardoso Galvão. Co-supervisore s: Ricardo Henrique Silva Santos e Anastáci a Fontanett i. The search for more sustainable production ways is an agriculture need. The no-ti ll organic corn production system meets several soil conse rvation principles. It provides contaminants free products, and it is responsible for making the agriculture less dependent of ex ternal inputs. The products, corn gra in and sweet corn, are critical to monogastric nutrition and human nutrition, which a re in a wide variety of Brazilian typical dishes. To find innovations that can led to viable al ternatives of production, the a im of this study was to evaluate the residual fertil izer effects in production components, gra in and sweet corn yield at different levels of organic compost and intercropping of jack bean (Canavalia ensiformis) and pigeonpea ( Cajanus cajan) with corn in no-till organic crop sy stem (NTOCS). The experiment was conducted in a random ized block design with six treatments and four replications. The treatments were: T1 – maize monoculture without fertil izer (Residual fertilizing from organic compost of 27 p revious crops); T2 – maize monoculture, fertil ized with 20 m3 ha-1 of organic compost; T3 – maize monoculture, fertil ized with 40 m3 ha-1 of organic compost; T4 – corn and jack b ean intercropped, fertil ized with 40 m3 ha-1 of organic compost; T5 – maize and dwa rf pigeonpea intercropped, fertil zed with 40 m3 ha-1 of organi c compost and T6 Maize and pigeon pea shrub intercropped, fertil zed with 40 m3 ha-1 of organic compost. The ANA VA was performed using the "F" test (p <0.05) and submitted to the "t" test (p <0.05) for comparison of two means. The organic compost was distributed on planting groove as determined in treatment immediatel y after planting. The corn crop wa s conducted in NTOCS with weeds management through mowing. Legumes were planted at the corn row at the sa me day. In the evaluation of production components of sw eet corn, there were no significant differences in the variables studied, ex cept for the proli fi cacy index. It is known that the s econd ear can compromise the mass, diameter and length of ears of sweet corn, compromising the market acceptance. Howeve r, although the proli fi cacy index had significant difference between treatment s, it was not able to d ecrease the spikes size produced in treatments. The results show that gra in yield and macronutrients exportation did not dif fer |
