Nitrogen fertilization split in green corn under rainfed system

Nitrogen fertilization split in green corn under rainfed system

According to Conab (2019), in the 2017/2018 harvest, the crop yield was 2.55 tons per hectare, a result caused by the non-use of appropriate technologies such as irrigation and balanced fertilization and also due to an irregular rainfall in the region.

Description
Summary:According to Conab (2019), in the 2017/2018 harvest, the crop yield was 2.55 tons per hectare, a result caused by the non-use of appropriate technologies such as irrigation and balanced fertilization and also due to an irregular rainfall in the region. [...]the destination of this grain for human consumption is also of great importance, especially in the Northeast region, where the cultivation of corn and the commercialization of ear of green corn enables the addition of value to the product, allowing the producer to acquire a higher price than that of the corn destined for grains (Rocha et al., 2011; Portela et al., 2016). [...]this product can be consumed both in its fresh form (cooked or roasted), as well as canned and processed in the form of tamale, cake, ice cream and several other traditional products, during all periods of the year (Pereira Filho et al., 2003; Mamede et al., 2009). Due to the complexity in the management of nitrogen fertilization, it is recommended that it is carried out in installments. [...]it is essential to carry out studies that evaluate the best way to split nitrogen fertilization in order to achieve a better use of this resource (Melo et al., 1999). According to the classification of Koppen, the climate of the region is of the hot Bsh-Semi-Arid type.
