“…The seed factor had a large participation on the final cost, representing a higher cost for AG9045 PRO2, representing an investment of 17.31% compared to the conventional seed. The same was observed on the conventional cultivars (2B604) and transgenic (2B604Hx) (Miguel et al, 2014). However, reductions of 10.00% and 7.20% in operating costs were observed with the adoption of Bt technology (Miguel et al, 2013;Silva et al, 2015).…”

Brazil, in lowland environment, corn has the potential for crop rotation with irrigated rice to minimizing infestations of red rice. The use of resistant cultivars associated to the use of insecticides are the main methods of control of the fall armyworm, Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae). However, there are lack of field studies that assess the crop’s production chain. The objective of this study was to evaluate the performance of corn cultivar, the conventional AG 9045 and the isogenic AG 9045 PRO2 Bt on the control of S. frugiperda, as well as to analyze the cost of production in the lowland environment. The cultivars were sown in the 2014/2015 and 2015/2016 harvests with adopted spacing of 0.7 meters and length of 5 meters. The application of insecticides was performed when the index of 10% of plants attacked by S. frugiperda was reached. Percentage (%) of attacked plants, corn productivity (kg ha-1) and cost of production (US$ ha-1) were evaluated. In the final analysis, the AG 9045 PRO2 isogenic Bt in conjunction to the chlorfenapyr + zeta-cypermethrin treatment show better efficiency on the control of S. frugiperda caterpillars, by a combination of two different control methods and active principles in the control of S. frugiperda, higher productivity indexes (3,155.58 kg ha-1) and profitability (-112.08 US$ ha-1).

“…Use of transgenic cultivars has as main advantage the reduction in the number of insecticide applications for lepidopteran control (Miguel et al, 2014). However, the transgenic seed cost is higher when in comparison to cultivars that do not have Bt proteins (Santos et al, 2017).…”

Soybean crop represents a large economic share in the Brazilian agricultural production. In Rio Grande do Sul (RS), with each new crop cycle there is an increase in the area under cultivation. In the lowland environment, the crop covers 5.4 million hectares, corresponding to about 20% of the State total area. Using transgenic cultivars whose main advantage is controlling target insects, as well as the reduced number of insecticide applications throughout the crop can be a viable alternative. However, the high cost of transgenic seed is considered as the main disadvantage in adopting this technology. The objective of this study was to evaluate the performance of cultivars RR1 and RR2 in relation to the occurrence of caterpillars and stink bugs, as well as to evaluate the production cost. The experiment was set up at Embrapa Clima Temperado in the crop seasons of 2014/2015 and 2015/2016, with conventional cultivars (BMX Potência (RR1 6.7)) and Bt isolines (BMX Ponta (IPRO 6.6)) and BMX Vanguarda (IPRO 6.0)). BMX Potência cultivar showed a higher incidence of defoliating caterpillars and Nezara viridula stinkbug, but it is the most indicated cultivar, among those evaluated, for the south lowland environment of RS, due to its yield and profitability.

“…Os avanços tecnológicos em melhoramento genético agregam à cultura do milho, grande potencial produtivo, destacando-se no Brasil a biotecnologia das sementes transgênicas resistentes a insetos e tolerantes a herbicidas, ou a combinação de ambas (MIGUEL et al, 2014). Como reflexo da maior resistência da planta ao ataque de insetos, é verificado o crescimento na produtividade de grãos (SILVEIRA, 2005).…”

RESUMO:O milho é um produto de grande importância na agricultura, em função de sua ampla utilização e das formas de produção. Tendo em vista esses cenários, o trabalho teve como objetivo a análise econômica do sistema de produção de milho utilizando diferentes híbridos de milho e preparos de solo. O estudo foi realizado na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas/UNESP de Botucatu-SP. Foram analisados dois híbridos em dois tipos de sistemas de preparo do solo, sendo milho convencional e milho transgênico, em preparo convencional e cultivo mínimo. Para os diferentes tipos de cultivo, foram utilizados os mesmos tratores, implementos e adubação, sendo o s seguintes parâmetros analisados: custos operacionais, custos de insumos, renda bruta, renda líquida e relação benefício/custo dos sistemas de cultivo. Conclui-se que a utilização de milho transgênico proporciona redução dos custos operacionais e com insumos, possibilitando, em preparo de cultivo mínimo do solo, maior produtividade, renda líquida e relação benefício/custo. PALAVRAS-CHAVE:custo operacional, produtividade, biotecnologia. ECONOMIC ANALYSIS OF CONVENTIONAL AND TRANSGENIC CORN UNDER TWO SOIL TILLAGE SYSTEMS ABSTRACT:Corn is an agricultural crop of major importance regarding its wide use and production forms. Given these background, this work aimed at analyzing economically the corn production chain with different hybrids and soil tillage systems. The study was carried out at the Experimental Farm of Lageado, located in the College of Agricultural Sciences/ UNESP, campus in Botucatu-SP, Brazil. We analyzed two corn hybrids, one conventional and another transgenic, on soil prepared by conventional cultivation practices and minimum cultivation. The same tractors, implements, and fertilizers were employed for both tillage systems. We evaluated operating costs, input costs, gross income, net income, as well as benefit and cost ratio of both cropping systems. Therefore, we concluded that transgenic corn provides reduced operating costs and inputs, enabling higher yield, net income and benefit/cost relationship when cropped with minimum cultivation practices.
