Studies on aflatoxin seed contamination of groundnut (Arachis hypogaea) in storage and its management using seed extract of Moringa oleifera and rhizome of Zingiber officinale was carried out on diseased seeds collected from Dutsin-Ma, Kurfi and Safana Local Government Areas of Katsina State, Nigeria between March and July, 2019. Aspergilus niger, A. flavus, A. ochraceus, A. tamari, A. parasitica, Rhizotonia spp, mucor spp and F. oxysporum were isolated. A. niger was the most frequently occurring pathogen in all the locations in March, 2019 with a range of 9 in Kurfi to 13 Dutsin-Ma and between 14 in Kurfi and 22 in Dutsin-Ma in July while the least was Mucor with a range of 3 in Dutsin-Ma and 6 in Kurfi both in July. Pathogenicity test conducted illicit rot in the healthy groundnut seeds. A. niger and A. flavus which were the most virulent pathogenic fungi responsible for aflatoxin contamination in groundnut seeds were controlled with the two extracts. Z. officinale was found to be more effective in the control of A. niger than M. oleifera at 40 g/L with inhibition of 60.32 % and at 120 g/L with inhibition of 87.33 % compared to M. oleifera which inhibited A. niger mycelial at 40 g/L by 59.79 % and at 120 g/L by 73.53 %. M. oleifera however, proved more efficacious in the management of A. flavus than Z. oficinale at 40 g/L and 80 g/L with percentage growth inhibition of 60.79 % and 62.47 %, respectively compared to a lower inhibition of 60.52 % and 60.94 % at 40 g/L and 80 g/L of Z. officinale, respectively. In both cases, the two extracts proved more effective on A. niger than A. flavus. It is therefore, recommended that extracts of Z. officinale and M. oleifera at different concentrations can be used to effectively manage rot pathogens of groundnut seeds in storage by farmers.

O trabalho teve por objetivo verificar diferenças entre rendimento do concentrado proteico e proteína bruta da folha da mandioca (Manihot esculenta Crantz), obtidos a partir de três variedades comerciais: branca, cascuda e vermelha. As manivas foram plantadas seguindo o delineamento experimental inteiramente casualizado com três repetições. Nas comparações entre as variedades, considerou coletas escalonadas pós-plantio, realizadas aos 12, 14 e 16 meses. O concentrado proteico foi obtido a partir da farinha das folhas inteiras e submetido ao método de termo - coagulação ácido e a proteína bruta pelo método padrão AOAC. Os dados foram submetidos a análise de variância e comparados pelo teste de Tukey - 5% de probabilidade. Os resultados não indicaram diferença significativa entre as médias obtidas para rendimento de concentrado proteico. Para a variável porcentagem de proteína bruta a variedade Branca foi a que apresentou maior valor, com média de 46,25%, seguida pela Cascuda e Vermelha, 44,52% e 37,30%, sucessivamente. Conclui-se que outros estudos devem avaliar condições que possam influenciar no teor de proteína foliar, como clima e solo, e, avaliar os níveis de ácido cianídrico de cada variedade, indicando qual das três é a melhor para a extração do concentrado proteico das folhas. Palavras chaves: Manihot esculenta Crantz, variedades comerciais, concentrado proteico, proteína bruta. ABSTRACT: The study aimed to assess the differences between income protein concentrate, crude protein of cassava leaf (Manihot esculenta Crantz), obtained from three commercial varieties: white, red and cascuda. The cuttings were planted following the completely randomized design with three replications. Comparisons between the varieties considered after planting staggered collections, held on 12, 14 and 16 months. The protein concentrate was obtained from flour of whole sheets and subjected to the term method - acid coagulation and crude protein by AOAC standard method. The data were submitted to ANOVA and Tukey test - 5% probability. The results indicated no significant difference between the mean values obtained for protein concentrate income. For the variable percentage of crude protein White variety showed the highest, with an average of 46.25%, followed by cascuda and Red, 44.52% and 37.30%, successively. We conclude that further studies should evaluate conditions that may affect the leaf protein content, such as climate and soil, and evaluate the hydrocyanic acid levels of each variety, indicating which of the three is the best for the extraction of protein concentrate from leaves Key words: Manihot esculenta Crantz, commercial varieties, protein concentrate, crude protein.
