“…In fact, gari produced from cassava harvested in the rainy season (15MAP) showed a reduction in starch content because of its mobilization for new shoot formation in the new growth cycle. This is in agreement with what was reported by Filho [ 57 ], Madore [ 58 ], Sriroth et al [ 59 ], Sagrilo et al [ 60 ], and Nuwamanya et al [ 49 ]. Furthermore, cassava roots starch may decrease progressively as plant aged after optimal starch storage ( Figure 3 ).…”

“…This might be due to varietal differences and harvest season as carbohydrate is highly concentrated during dry season compared to the rainy season. The reduction of carbohydrate for the gari samples obtained at 15 months was probably due to the rain which facilitates the hydrolysis of carbohydrate to sugar for shoots regrowth after prolonged water stress [ 60 ].…”
This study is aimed at evaluating the proximate composition and functional and sensory characteristics of gari obtained from five cassava varieties (EN, AD, TMS92/0326, TMS96/1414, and IRAD4115). These cassavas were harvested during the dry season 12 months after planting (12MAP) and in the rainy season (15MAP). Results showed that the characteristics of gari varied significantly (p < 0.05) with the variety and the harvest period. Gari from EN cassava harvested at 12MAP had the highest total carbohydrates (78.07% dry weight), starch (61%), and proteins content, while gari from TMS 96/1414 variety (12MAP) had high amino acids (10.25 mg/g) and phenolic compounds (9.31 mg/g) content. The gari from IRAD4115 had the highest value of ash content (20.62 mg/g) at 12MAP. The soluble sugar content was high in the gari from cassava harvested at 12MAP while free cyanide reduced significantly in gari from cassava harvested at 12MAP. The water absorption capacity, swelling power, and bulk density were significantly (p < 0.05) high in the gari from EN cassava variety at 12MAP. Compared to commercial gari (3.30), gari from EN local cassava had the best overall acceptability (4.35) followed by those obtained from TMS92/0326 and TMS92/1414 varieties, respectively.

“…Furthermore, Sagrilo et al (2002) assessed the performance of cassava cultivars in the Northwest Paraná at different harvest times and concluded that, for those conditions, the physiological rest period at the end of the second crop cycle was more indicated for harvest, due to the higher production of the storage root fresh and dry matter and starch. Sagrilo et al (2003) observed that the cultivars IAC 13, IAC 14 and Fécula Branca had high dry matter content in the storage roots. They also emphasized the importance of selecting the genotypes which had high dry matter content in the storage roots, to obtain better yield.…”
“…Therefore, assessments were carried out in a total of eight different environments. The soils of both the locations have been classified as distrophic Red latosoil (Embrapa, 1999;Sagrilo et al, 2003). The climate of Maringá is Cw´h type, (according to Köppen' classification), with a mean annual temperature of 22.4°C and mean annual rainfall of 1,639 mm, while that of Araruna is Cfb type, with a mean annual temperature of 21.5°C…”
