Influence of compost prepared from household waste and poultry manure in compost- soil mixtures on the growth and yield of Lettuce (Lactuca sativa L)
Journal Title: Scientia Agriculturae - Year 2016, Vol 13, Issue 3
Abstract
Lettuce (Lactuca sativa L.) is an essential leafy vegetable which is often used in salads and other culinary recipes in Ghana. A pot experiment was conducted on a loamy sand soil to study the effect of different compost: soil mixtures on the growth and yield of lettuce. The compost were prepared from household waste and poultry manure in a ratio of 3:1. The compost soil mixtures were 100% compost (T1), 75% compost+25% soil (T2), 50% compost+50% soil (T3), 25% compost+75% soil (T4), 100% soil (control)(T5), poultry manure+soil (T6), mineral fertilizer NPK(15- 15- 15)+soil (T7), mineral fertilizer NPK(15- 15- 15)+compost+soil (T8). The growth parameters studied were plant height, canopy spread, number of leaves per plant and the leaf area. The yield parameters were fresh weight, dry weight and shoot to root ratio. The different treatments had significant (p<0.05) effects on the growth and yield parameters studied. The soil- compost/fertilizer/manure mixtures had variable levels of nutrients. Thus none of them could be ranked as the richest in all nutrients. The soil- compost mixture of 75% soil+ 25 compost gave the overall best while the least was recorded by the control in terms growth and yield. Compost containing mixtures performed better than the control.
