Abstract:
To investigate the effects of organic fertilizers made from cassava processing waste (cassava peel and cassava residue) on the growth,yield and quality of watermelon,in order to provide the basis of cassava processing waste resources converted into fertilizer in locally.By two years of continuous testing,the experiment included four treatments,i e single application of organic fertilizer(treatment A),combined application of organic fertilizer and chemical fertilizer(treatment B),that no fertilizer (CK-1) and chemical fertilizer (CK-2) as the blank and conventional fertilization control respectively,the total amount of N,P and K nutrient in all fertilization treatments were 750 kg?hm-2,then the main stem length,stem diameter,number of effective branches,yield and quality were investigated to evaluate comprehensively effect of cassava processing waste-derived organic fertilizer.The results showed that,compared with blank control (CK-1) treatment,all the fertilization treatments could promote the growth of watermelon and increase watermelon fruit′s yield and quality of in the two years.Compared with conventional fertilizer (CK-2) treatment,in the first year,a treatment inhibited the growth of watermelon,and the yield decreased significantly,but the quality was improved obviously.In the second year,watermelon growth inhibition degree was reduced,and the yield had no significant difference with CK-2,but the quality was still significantly higher than CK-2.But in two consecutive years,the watermelon growth,yield and quality of B treatment were all superior than those of conventional fertilization treatment.So that,cassava processing waste-derived organic fertilizer applied with chemical fertilizer,could effectively promote the growth of watermelon plant,at the end increased the production and quality of watermelon fruits.
