Effect of Biostimulants on potato production (Solanum tuberosum L.) for the Totora area in Cochabamba, Bolivia

Abstract

In order to evaluate the effect of Biostimulants on potato production (Solanum tuberosum L.) in Totora, Cochabamba, experimental plots were implemented with the seed company SEPA. Field trials were implemented in experimental design of Randomous Complement Blocs (DBCA) with sub-sampling and four repetitions. Six treatments were implemented: T1: Witness (without application), T2: Tricobal (applied to seed), T3: Fostop (applied to seed), T4: Energy top (applying to the seed), T5: Maxim SEPA (Fludioxonil and Metalaxil-M) to the seed Energy Top (applied to foliage) and T6: Maxim SEPA (Fludioxonil and Metalaxil-M ) to the sequerum (applied to the foliage). The results showed that there was a high and positive correlation between the chlorophyll content and performance. This suggests that the variables are not independent, and biostimulants affect photosynthesis. It was observed that the higher chlorophyll content in the leaves increases performance on average. The best treatments were for the T6 (Maxim to the seed - Tricobal applied to the foliage), with yield of 30 t/ha and Energy top with 26 t/ha, with the highest numbers of tubers per plant and the higher Marginal Return Rate (Bs 24,31).
