Abstract

Corchorus olitorius (L.) is an important leafy vegetable known for its rich source of several nutrients and dietary fibre in Africa, Asia and some parts of America. One major limitation of cultivating Corchorus olitorius in the tropics is inadequate soil fertility. Fertilizer application is an integral part of the vegetable cultivation due to low soil productivity. The study therefore aims at evaluating the effects of organic, inorganic and organo-mineral fertilizer at different concertation on the growth, yield and nutrient composition of Corchorus olitorious. The experimental setup followed a complete randomized block design with three replicates. Treatments include control, 1,000 kgha-1 sole poultry manure (PM), 2,000 kgha-1 sole PM, 200 kgha-1 sole NPK, 400 kgha-1 sole NPK, 600 kgha-1 sole NPK, 1,000 kgha-1 PM+200 kgha-1 NPK, 1,000 kgha-1 PM+400 kgha-1 NPK, 1,000 kgha-1 PM+600 kgha-1 NPK, 2,000 kgha-1 PM+200 kg/ha NPK, 2,000 kgha-1 PM+400 kgha-1 NPK and 2,000 kgha-1 PM+600 kgha-1 NPK fertilizer combinations. The growth, yield and nutrient composition of C. olitorious plants were significantly enhanced in all fertilizer treated plots in comparison to the control. Significantly (p<0.05) higher growth parameters, yield and nutrient composition were recorded in the plots treated with combined application of both fertilizers at 2,000 kgha-1 PM+400 kgha-1 NPK and 2,000 kgha-1 PM+600 kgha-1 NPK when compared to other application combinations. This study affirms that the combined application of organic and inorganic fertilizer as a soil amendment could enhance growth, yield, and nutrient composition of C. olitorious in comparison with sole application of either fertilizers.

Highlights

Corchorus olitorius known commonly as ‘fruited jute’, ‘bush okra’ or ‘jute mallow’ is a common tropical leafy vegetable found in Africa, Asia and some parts of the Middle East and Latin America (Odofin et al, 2011)
One of the major challenges of crop production in the tropics is inadequate soil fertility which results from soil erosion, denitrification, overgrazing, deforestation and other human activities (Adediran et al, 2015)
The aim of this study is to evaluate the effect of organic, inorganic and organo-mineral fertilizer applications on the vegetative growth, productivity and nutrient constituents of Corchorus olitorious

Summary

Introduction

Corchorus olitorius known commonly as ‘fruited jute’, ‘bush okra’ or ‘jute mallow’ is a common tropical leafy vegetable found in Africa, Asia and some parts of the Middle East and Latin America (Odofin et al, 2011) It has succulent leaves which soften rapidly with cooking, and thickens into a viscous mucilaginous soup which can be eaten with starchy foods (Adediran et al, 2015). Several studies have confirmed the use of organic manure as a better alternative to chemical fertilizer (Abd El-Megeed et al, 2000; Mahmoud et al, 2000; Mohamed and Gabr, 2002) This is because it is cheap and affordable, eco-friendly and it had a profound effect on the activity of soil microflora as well as soil physico-chemical properties (Ghoneim and ElAraby, 2003). The aim of this study is to evaluate the effect of organic, inorganic and organo-mineral fertilizer applications on the vegetative growth, productivity and nutrient constituents of Corchorus olitorious
