Abstract

Productive performance of baby corn organic fertilization and its influence on fall armyworm.

Abstract

Corn, in its form of baby corn cultivation, meets the requirements of consumers because of its delicacy and low caloric value when compared to conventional maize (grain). In order to evaluate the productivity of baby corn fertilized with different doses of organic compost and its influence on the fall armyworm an experiment with six treatments based on organic compost was installed (0, 4, 8, 12, 16 e 20 Mg ha-1), in randomized blocks with 10 repetitions. Assessments of damage caused by caterpillar were performed at seven, 14, 21, 28, 35, 42 and 49 days after plant emergence. For the baby corn productivity, the evaluations were based on the number of commercial ears, as well as the weight, length and diameter of commercial ears in each treatment. The results of baby corn yield, ear length, diameter and weight, as well as caterpillar were not affected by the different doses of organic compound. Information in this regard may contribute to the decision of the producer, as the many hybrids destined for the production of baby corn already have high productive potential and would not require complementary chemical fertilizers, as well as not to provide environmental problems through fertilization with nitrogen N. excess.
