Agronomic performance of banana plantain (Musa paradisiaca L.) cv. CEMSA ¾ by selecting corms based on productivity Potosí, Rivas, 2015

Abstract

A field experiment was carried out at San Antonio Farm located in Potosí, Rivas from October 2014 to December 2015. Two experimental plots were established with 250 plants each. The variety of banana plantain (Musa paradisiaca L.) cv. CEMSA ¾ was used. The experiment was established on October 23th, 2014. Suckers from plants with bunch with 40 or more fingers was selected to establish the superior plot (Treatment 1). In the test plot the suckers was selected by the farmer (Treatment 2). Rows with 25 plants at 2.4 m between rows and 1.3 m among plants for a density of 3200 plants per hectare. T-test per independent plots and multiple correlation were used to analyze the data. The bunch weigh was 20.44 kg for test plot and 20.31 kg for superior plot (P= 0.714). The number of hand per bunch were 10.06 per test plot and 10.39 for the superior (P=0.002). The number of fingers per bunch was 51.51 per test plot and 52.95 for the superior (P=0.019). The fi nger length was 32.45 cm for the test plot and 31.74 cm for the superior plot (P=0.016). The diameter of fi nger was15.67 cm for test plot and 15.35 cm for the superior plot (P=0.006). The mean weigh of fi nger was 367.0 g test plot and 344.9 g for superior plot. The total yield was 58.86 t ha-1 in the test plot and 58.49 t ha-1 in the superior plot. The field experiment will continue with the harvest 2016 and 2017.
