“EFECTO DE POLLINAZA Y TORTA DE PIÑÓN COMO FUENTES NITROGENADAS EN CUATRO DOSIS SOBRE EL DESARROLLO PRODUCTIVO DE ALGODÓN (Gossypium hirsutum L.)”

Abstract

COTTON (GOSSYPIUM HIRSUTUM L.) IS A VERY IMPORTANT NON-FOOD CASH CROP AS IT IS AN IMPORTANT SOURCE OF FOREIGN EXCHANGE EARNINGS FOR SOME COUNTRIES. COTTON CULTIVATION IS VERY DEMANDING IN NUTRIENTS, ESPECIALLY NITROGEN, WIDELY USED IN A MINERAL FORM THAT IS NOT ECONOMICALLY VIABLE OR ENVIRONMENTALLY ACCEPTABLE. THAT IS WHY IT IS ESSENTIAL TO STUDY OTHER ORGANIC NITROGEN SOURCES. THE MAIN OBJECTIVE OF THE PRESENT INVESTIGATION WAS TO EVALUATE THE EFFECT OF CHICKEN MANURE AND PINE NUT CAKE AS NITROGENOUS SOURCES IN FOUR DOSES ON THE PRODUCTIVE DEVELOPMENT OF COTTON. THIS RESEARCH WAS CARRIED OUT BETWEEN NOVEMBER 2019 TO APRIL 2020 AT THE LA TEODOMIRA EXPERIMENTAL CAMPUS BELONGING TO THE FACULTY OF AGRONOMIC ENGINEERING OF THE TECHNICAL UNIVERSITY OF MANABÍ, LOCATED IN THE LODANA PARISH, BELONGING TO THE SANTA ANA CANTON, PROVINCE OF MANABÍ.
