“Evaluación del crecimiento radicular y nodulación de variedades de maní bajo tres láminas de agua riego”

Abstract

THE TEST OF THE AGRONOMIC BEHAVIOR OF PEANUT (ARACHIS HYPOGAEA L.) WAS AS A STUDY TO ESTABLISH THE EFFECT OF THREE LOCALIZED IRRIGATION SHEETS ON THE DEVELOPMENT AND GROWTH OF THE ROOTS AND NODULES OF THE PEANUT PLANT. FOUR VARIETIES WERE USED: CARAMEL: INIAP 382, ​​BLACK: INIAP 380, PINK: INIAP 381, STRIPED: INIAP 383. THE METHODOLOGY ALLOWED THE USE OF A COMPLETELY RANDOM EXPERIMENTAL DESIGN (DBCA), CARRYING OUT IN THE MONTH OF SEPTEMBER 2021 WITH A REA WORKED 32 M2 LONG AND WITH A WIDTH 1.30CM. WITH THE APPLICATION OF THREE WATER SHEET WHERE FACTORS A WERE ESTABLISHED WITH STUDIES WITH MAIN PLOTS, IRRIGATION LEVELS AND FACTOR B IN THE CULTIVAR SUBPLOTS. THE INFLUENCE OF THE IRRIGATION SHEETS ON THE CROP SHOWED SIGNIFICANT DIFFERENCES IN THE VARIABLE IN STAGES OF VEGETATIVE DEVELOPMENT OF THE CROP. IN THE VARIABLE NUMBER OF NODULES HAD AN AVERAGE VALUE OF 767 FOR THE ROSITA VARIETY UNDER CONDITIONS OF KC 0.2 WATER DEFICIT. THE EVALUATED PARAMETERS OF DRY WEIGHT OF NODULES IN THE VEGETATIVE DEVELOPMENT PHASE RESULTED IN AN AVERAGE OF 46 CORRESPONDING TO THE CANDY VARIETY STUDY IN THE KC 0.2 WATER SHEET. WITHIN THE VARIABLES EVALUATED OF THE ROOT VOLUME IN THE PHASE OF VEGETATIVE DEVELOPMENT, THE VARIETIES THAT SHOWED THE LARGEST MARKETS ARE CARAMEL AND BLACK WITH VALUES OF 86 AND 85ML IN THE KC 0.2, KC 0.5. WHILE IN THE VARIABLE IN THE ROOT LENGTH IN THE DEVELOPMENT PHASE SHOWED AN AVERAGE OF 19CM WITH ITS VARIABILITY COEFFICIENT REACHED OF 9.31% UNDER KC CONDITIONS 0.2. THE VARIABLES EVALUATED IN THE DRY ROOT MATTER WE OBTAINED IN THE NEGRO VARIETY A SIGNIFICANT AVERAGE OF 3.53GR AT A KC 0.5.
