Mineral, organic and biological fertilization on common bean production in Santa Rosa de Copán

Abstract

The objective of the following investigation was to evaluate the effect of mineral, organic and biological fertilization on the production of common bean (Phaseolus vulgaris L.). A trial was developed during the months of February to May 2015. The study was conducted on the farm "El Padre", in the municipality of "Montañita" ,province of Copán, located at 12 km from the city of Santa Rosa de Copán. A random block design (BCA) was used with eight treatments and four repetitions each for a total of 32 experimental units (EU). The EU consisted in 8 square meters lots each (4 rows to 0.45 m and 5 m in length). The fertilizer used were 12-24-12, 46% of urea and 60% of KCl combined into a soil analysis formula. A combination of Vermicompost at 4 ton.ha-1 deposited at the bottom and mycorrhizal fungi pelleted seed was used (the bright red variety called Amadeus-77). There was significant difference in the weight of 100 grains, because the compost seeds treatment achieved greater weight (27.68 g) with respect to the control (22.61 g). The effect of the treatments was not significant for the growth of the plant at 65 DDS, leaf area and yield, while the combination of compost + micorriza had greater number of legumes per plant. The fertilizer + compost + micorriza treatment was the one with the largest number of grains per pod.
