Estudio de tiempos y movimientos para la polinización artificial: estudio de caso en una plantación de Santander (Colombia)*
Bud rot (BR) is the most limiting disease for oil palm crops in Colombia. Since some crossings between Elaeis oleifera and Elaeis guineensis (hybrids OxG) have proven a certain degree of resistance to the attack of BR, they have been planted in Colombian regions that suffered from BR outbreaks. However, a deficient natural pollination is a characteristic of hybrids OxG, which in turn, limits the production of oil palm fresh fruit bunches. The latter has forced hybrid OxG growers to implement strategies such as the assisted pollination (applying pollen from E. guineensis on flowers at anthesis) and the artificial pollination (applying α-naph- thaleneacetic acid (NAA) on flowers that need to be pollinized). These strategies have shown good results in terms of bunch formation and increase in the oil content of fruits, so growers have been prone to adopt them in order to benefit from the resistance to BR and having a profitable business. This paper focuses on artificial pollination from a labor productivity standpoint. It must be highlighted that companies have modified the method suggested by Cenipalma for applying NAA. Instead of using a liquid solution containing NAA (as recommended by Cenipalma), they have implemented a solid mixture containing NAA, arguing that it is easier to handle in the fields. The results of the method implemented by growers have been also promising and have achieved good indicators of bunch formation and oil content. A time and motion study was carried out in order to describe the method of applying a solid mixture of NAA on flowers requiring pollination. It was carried out at a plantation from Santander (Colombia) that has shown excellent results with this method. Besides describing the method, the goal of this study was to measure labor productivity for artificial pollination (by using a solid mixture containing NAA). Results indicate that at a working day a worker covers an area of 1.99 ha and the total cost of an application per flower is COP 306 (including labor, tools and inputs).
