Abstract

Cassava is one of the most important socio-economic crops in the world. It is usually cultivated in soils with low fertility and little mechanization, which makes it difficult to increase the crop's productivity and, consequently, economic gains. The aim of this study was to evaluate different types of fertilization (Poultry litter, organomineral fertilizer and rooting) in cassava cultivation in the northwest region of the state of Paraná - Brazil. After 10 months of planting, the variables evaluated were: number of roots, root diameter, root length, shoot height, starch yield and shoot fresh weight. The results were submitted to mean test, principal component analysis and Pearson's R correlation analysis. The results showed that poultry litter presented the best result in practically all the evaluated variables, followed by rooting, which promoted the highest number of roots; in addition, with the exception of the number of roots, all other variables were highly correlated.

Highlights

1.1 Manihot Escullenta CrantzCassava (Manihot esculenta Crantz) is a tuberous plant, of the Euphorbiaceae family, and has Brazil as a possible center of origin and diversification of the cultivated species. (Abraham, 1970; Fukuda et al, 2005)
It is possible to verify that for the plant height parameter, the tallest plants were those of the treatment 3 (T3) treatment, followed by the T1 treatment and the plants with the smallest height were those of the control (T4)
For the starch yield variable, treatment T3 was superior to all other treatments, with T1 having the second highest starch yield, followed by T2 and the lowest starch yield value was obtained in treatment T4

Summary

Introduction

1.1 Manihot Escullenta CrantzCassava (Manihot esculenta Crantz) is a tuberous plant, of the Euphorbiaceae family, and has Brazil as a possible center of origin and diversification of the cultivated species. (Abraham, 1970; Fukuda et al, 2005). Cassava (Manihot esculenta Crantz) is a tuberous plant, of the Euphorbiaceae family, and has Brazil as a possible center of origin and diversification of the cultivated species. The great importance of this culture is due to the fact that about half a billion people around the world have cassava as a primary source of carbohydrates (Isendahl, 2011). In Brazil, studies show that 59% of the population consume this tuber at least every two days (Horodyska et al, 2021). This is a considerable amount, especially when we talk about cassava production. There are two types of cassava grown in Brazil. Wild cassava (requires detoxification for human consumption and is widely used for the production of flour) and does not require fertile soil for production; and sweet cassava (suitable for human consumption and requires fertile soil for production) (Fraser, 2010)
