Effect of Organo Mineral Fertiliser and Poultry Manure on the growth, proximate and nutritional analysis of two cultivated varieties of Corchorus olitorious

Abstract

A pot experiment was conducted at the Experimental site of the Department of Agricultural Technology, Oyo State College of Agriculture and Technology, Igboora to evaluate the effect of organomineral fertiliser and poultry manure on growth, proximate and nutritional analysis of two cultivated varieties of Corchorus olitorius (Angbadu and Oniyaya).The experimental design was a 2 x 3 factorial arrangement in Complete Randomized Design (CRD) and replicated four times. The treatments were 0 t/ha-1(Control) and 10 t/ha-1 (poultry manure and organomineral fertiliser). Data were collected on the growth parameters (number of leaves, plant height and stem girth) at 3, 4, 5 and 6 weeks after planting (WAP). Proximate composition of the shoots (leaves and stems) and roots were evaluated. Results obtained showed that there was a significant effect of the application of poultry manure and organomineral fertiliser at 10t/ha-1 on the growth components of the 2 varieties compared to the control. There were significant differences in the leaf count among the treatments with the treatment that had poultry manure application producing the highest leaf count of 68.5 in the Angbadu variety. There was also a significant effect of the application of poultry manure and organomineral fertiliser on the proximate analysis of the varieties. As regards proximate analysis, the Angbadu variety of Corchorus olitorius that had the application of organomineral fertiliser had a higher mean value of crude protein (9.63%), crude fibre (6.04%), dry matter (87.35%) and total carbohydrates (61.67%). Poultry manure and organomineral fertiliser could serve as sources of nutrients for Corchorus olitorius production where available.
