Effect of Organic and Inorganic Fertilizer on the Proximate Content of Seedlings of Five Cassava Varieties

Abstract

Cassava is the largest source of food carbohydrate in the tropics. A new hybrid of cassava is the yellow variety with some new varieties from International Institute of Tropical Agriculture. The high preference served around the consumer is due to its high yield and high concentration of Bcarotene, a precursor of vitamin A. It also resistant to pests and drought, the yellow variety attracts a lot of investigation towards their stabilization. The study therefore, investigated the effect of organic and inorganic fertilizer on the proximate content of the young seedling of three varieties of cassava. The selected varieties were IITA-TMS-IBA 30572, IITA-TMS-IBA 070593, and IITA-TMS-TMEB419. Young seedlings were raised in 9 cm Petri dish in the laboratory.
Sprouting seeds were planted on sterile sandy loamy soil. The growth promoters used were Inorganic fertilizer (NPK) and Organic fertilizer (cow dung and compost). Proximate analysis including moisture content, dry matter, fat, ash content, crude fiber, crude protein, total sugar, starch and total cyanide. All the proximate components investigated in the seedlings varied.
Seedlings treated with NPK showed high moisture content in all varieties. Compost manure enhances all the component of the proximate analysis in the three varieties investigated. Organic fertilizer enhanced the proximate component in the root of IITA-TMS-IBA 070593 only.
