Abstract

Sugarcane, one of the crops of compact potential, is productive in Brazil, cultivated in the most diverse regions of the country, among the problems that the heavy drop in productivity, the use of heavy machinery and its traffic provides an increase in the intensity of the soil, hindering the emergence of crop profiles, which considerably increases the costs due to these failures in the middle of the productive area. Interacting with technologies in favor of the agricultural environment, it is able to obtain measurements in the crops with the sugarcane crop, counting and projecting them under a cultivated area. Through the use of aerial images, it is possible to determine the failures presented in the planting lines. Considering that, over time, culture can be defined as likely to form a trend, this could be a possibility over the possible overlap of the possibility. In this way, the present work aims to determine how failures in sugarcane planting lines with the use of aerial images in the midst of a relationship with the measurement of failure in loco and as productive characteristics of the culture. The experimental design will be implemented in the production area belonging to Ipira Agroindús, in the Unit located in the municipality of Descalvado, belonging to the State of São Paulo, and two areas with the sugarcane variety CTC 4 will be adopted. . blocks at random, adhering to an arrangement with 5 blocks and 5 fault sizes, totaling 5 experimental plots. Application analysis functions and their use are increasing application analysis function and the use of images to control function of control function of your application. Corn silage represents the main source of roughage in the diet of dairy herds and confined cattle in Brazil (Bernardes & Rêgo, 2014; Oliveira & Millen, 2014). It is known that the main source of energy for this forage comes from non-fibrous carbohydrates, especially the starch present in the grains (Allen et al., 1997). However, corn hybrids sold in the country are basically of the flint type (Pereira et al., 2004) and represent more than 95% of all corn used in the diet of confined cattle (Oliveira & Millen, 2014). Flint hybrids are widely used because they have greater resistance to adverse environmental conditions and attack by pests and diseases, however, the corn grain of these hybrids has greater resistance to the attack of ruminal microorganisms due to the greater proportion of vitreous endosperm compared to dent hybrids (Philippeau et al., 1999), reducing starch digestibility (Correa et al., 2002). In this way, the search for strategies that improve the efficiency of use of corn silage and the starch fraction in order to optimize animal production is necessary. Studies have shown that the maturity stage (Der Bedrosian et al., 2012; Windle et al., 2014), use of bacterial inoculants (Hu et al., 2009) and silage storage time (Daniel et al., 2015; Hoffman et al., 2011) alter the fermentation process and may have a direct effect on starch availability. Another factor pointed out by Hallada et al. (2008) is the neutral detergent fiber (NDF) digestibility of corn silage that increased as storage time increased. It is known that during the fermentation process, some degradation of hemicellulose is expected due to acid hydrolysis and/or enzymatic action of some microorganisms (McDonald et al., 1991). However, the cause for the increase in NDF digestibility is not yet established. Additionally, there are still few studies conducted with flint hybrids and in tropical conditions that investigate the effect of prolonged silage storage and when we consider the interaction between maturity stage, bacterial inoculation and storage time, the current results are controversial.
