Índice de área foliar, spad e massa de matéria seca do feijoeiro comum em função dos bioestimulantes, NPK e micronutrientes em Vitória da Conquista – BA

Abstract: A cultura do feijão apresenta grande importância econômica e social no Brasil e estudos sobre a função dos bioestimulantes associados a diferentes adubações nessa cultura ainda são incipientes. Desse modo, objetivou-se com este trabalho avaliar a influência do uso de bioestimulantes e suas interações com as adubações de NPK e micronutrientes no índice SPAD, índice de área foliar e a massa de matéria seca do feijoeiro da cultivar de feijão Pérola no município de Vitória da Conquista - BA. O trabalho foi desenvo… Show more

“…The more available nutrients are in the soil, the greater the LAI, because the larger plants create demands for nutrients that must be satisfied by the complementary fertilization of the soil. However, fertilization of NPK and micronutrients together provided higher LAI than fertilization of micronutrients and NPK when used alone [10].…”

“…Para Anjos et al (2017), os bioestimulantes usados conjuntamente com a adubação de NPK aumentaram o índice de área foliar e o da massa seca das hastes em feijoeiro comum. Porém os reguladores influenciam a resposta de muitos órgãos da planta, mas essa resposta depende de cada espécie, parte da planta, estádio de desenvolvimento, concentração, da interação entre os outros reguladores e de vários fatores ambientais (CAMPOS et al, 2011).…”

“…When applied in small amounts, the biostimulant affects the growth of the plant and its development, as in the bean plant that plays an important role in the development, making the plant more resistant to environmental stresses . Researches on the use of biostimulants, associated or not to fertilization (Anjos at al., 2017), have been developed and the responses are quite contrasting, which opens up space for further research, in order to elucidate affirmative answers about the use of these substances in agriculture. Abrantes et al (2011), under Cerrado conditions, observed that the application of biostimulant increased the number of grains per plant and grain yield in common bean.…”
