Open-access Fertilizer use of guava processing industry waste

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    The guava processing industry waste (GPIW) has been used in some areas, however is not known its effect on soil fertility. A greenhouse experiment was carried out to evaluate the effect of GPIW on soil fertility, using corn as testing plant. The experiment was in randomized blocks design combining five GPIW rates (0; 20; 40; 60 and 80 t ha-1) in the absence and the presence of mineral fertilization. The GPIW increased P and K concentration and behaved as a slow release source of N and P for corn.
