Özet:

 The multi uses of cassava plant Manihot esculenta Crantz has increased its demand and value. However, the production rate is far below the potential as a result of use of unimproved varieties and lack of soil amendment to enhance productivity. This study thus compared the performances of some old and newly released cassava varieties in both organic, inorganic and unamended soil at Ogbagu Ogume. Stems of newly released Obasanjo2, Baba70, and Game changer and old TME419 and Give-Me-Chance-GMC were planted in farmlands amended with 400 kgha NPK 15:15:15, 4.2 tha poultry manure and 5-year old fallowed land control for 2023 and repeated in 2024 planting seasons. The experimental design was a 5varieties x 3nutrient source x 2seasons factorial arranged in a randomized complete block design and replicated three times. The soil and leaf macro and microelements were also determined using standard procedures. Data were taken on the fresh tuber weight FTW at harvest. Data collected were analysed using ANOVA and means were separated using least significant differences at 5 significance level. The macro and micro elements of the soil decreased from the pre to post status while the leaf nutrient content were insignificant across the genotypes. The FTW differed significantly across the varieties, nutrient source and year and ranged from 21.330.59 TME419 to 34.330.59 Obasanjo2, 26.950.46 Fallowed soil to 29.220.46 NPK 15:15:15, and from 25.950.37 year two to 29.960.37 year one, respectively. Planting improved varieties in a NPK 15:15:15 amended soil at 400 kgha enhances cassava output, thus recommended.
