Respuesta adaptativa de híbridos comerciales foráneos de piñón (Jatropha curcas L.), en la parroquia Lodana

Abstract

THE PHYSIC NUT (JATROPHA CURCAS L.) IS A DROUGHT RESISTANT MULTIPURPOSE SPECIES THAT CAN BE CULTIVATED ON MARGINAL SURFACES, WITHOUT COMPETING WITH THE PRODUCTION OF FOOD CROPS, WITHOUT, HOWEVER, ITS PRODUCTION IS NOT PROFITABLE. IT IS MENTIONED THAT JATROPHA HYBRIDS PROVIDE A HIGHER PRODUCTIVITY THAN EXISTING MATERIALS IN ECUADOR. THE PRESENT INVESTIGATION HAS AS MAIN OBJECTIVE TO EVALUATE THE ADAPTIVE RESPONSE OF COMMERCIAL FOREIGN HYBRIDS OF PHYSIC NUT IN THE PARISH OF LODANA, SANTA ANA - MANABÍ. A COMPLETELY RANDOM BLOCK DESIGN WAS USED, STUDYING SIX TREATMENTS CONSISTING OF FOUR HYBRIDS INTRODUCED FROM INDIA (T1. HYBRID JAT 001100, T2. HYBRID JAT 001103, T3. HYBRID JAT 001164, T4. HYBRID JAT 001165) AND THE PROMISING VARIETIES FROM THE GERMPLASM BANK OF THE INSTITUTO NACIONAL DE INVESTIGACIONES AGROPECUARIAS (T5. CP-041 AND T6. CP-052) WITH FOUR REPETITIONS, ACHIEVING A TOTAL OF 24 EXPERIMENTAL UNITS, WHICH WERE DIVIDED INTO FOUR PLOTS, WHERE EACH PLOT CONTAINED SIX PLANTS, TOTALING 24 PLANTS PER TREATMENT. AFTER THE ESTABLISHMENT OF THE TEST, THE PLANT HEIGHT, STEM DIAMETER, NUMBER OF BRANCHES AND INFLORESCENCES, WEIGHT OF NUTS AND SEEDS, THE SPAD INDEX OF LEAF CHLOROPHYLL AT THE BEGINNING OF FRUCTIFICATION, EVALUATION OF ARTHROPOFAUNA, YIELD T/HA AND PERCENTAGE OF ACCEPTANCE AT THE END OF THE EVALUATION PERIOD. THE RESULTS WERE SUBJECTED TO AN ANALYSIS OF VARIANCE AND TUKEY'S AVERAGE ASSUMPTIONS TO VERIFY NORMALITY AND HOMOSCEDASTICITY ASSUMPTIONS USING SHAPIRO-WILK AND HARTLEY'S ASSUMPTIONS. YIELD AND SEED WEIGHT WERE SHOWN TO BE CORRELATED WITH THE TOTAL NUMBER OF INFLORESCENCES. THE FOREIGN AND LOCAL HYBRIDS PRESENTED A GOOD BEHAVIOR HIGHLIGHTING THE T3 INDIAN ORIGIN, WHICH PRESENTED THE BEST RESULTS IN THE DIFFERENT VARIABLES.
