“Efecto de densidades poblacionales del fréjol (Vigna unguiculata L. Walp) variedad INIAP-463 con dos fertilizantes inorgánicos”

Abstract

IN THE PRESENT RESEARCH WORK, THREE POPULATION DENSITIES AND TWO TYPES OF SYNTHETIC FERTILIZERS NOVATEC (N15, P3, K20) AND YARAMILA (N12, P9, K18) WERE EVALUATED, IN ORDER TO DEMONSTRATE WHICH DENSITY AND FERTILIZER GIVE THE HIGHEST YIELD IN THE VARIETY. OF BEANS INIAP-463. THE OBJECTIVE OF THE RESEARCH WAS TO "EVALUATE THE EFFECT OF POPULATION DENSITIES OF BEANS (VIGNA UNGUICULATA L. WALP) VARIETY INIAP-463, WITH TWO INORGANIC FERTILIZERS IN THE MACONTA COMMUNITY OF THE COLÓN PARISH." A COMPLETELY RANDOMIZED BLOCK DESIGN (DBCA) (3X2+3) WITH 3 REPLICATIONS AND NINE TREATMENTS IN A TOTAL AREA OF 450 M2 WAS USED. THE DENSITIES AND PLANTING DISTANCE WERE: D1, 1M X 0.60 M = 33.333PL/HA; D2, 1M X 0.50M = 40,000 PLANTS/HA; D3, 1M X 0.40M = 50,000 PLANTS/HA. THE VARIABLES EVALUATED WERE GERMINATION PERCENTAGE (%), GUIDE LENGTH (CM), STEM DIAMETER (MM), CHLOROPHYLL INDEX (SPAD UNITS), POD LENGTH, NUMBER OF PODS, DRY GRAIN YIELD IN KG/HA, HUNDRED SEED WEIGHTS TO GRAMS AND AGRONOMIC NUTRIENT EFFICIENCY (AE).
