| Abstract: | Incorporation of compost in soil will not only protect the environment, but also take advantage of the nutrients and organic
matter contained in the compost to enhance soil fertility and crop production. Field experiments were carried out during the
2006/2007 and 2007/2008 growing seasons at the College of Food and Agriculture Farm, United Arab Emirates University. The
experiments were established in randomized complete block design (RCBD) with four replications. The plot dimension was 3.2m×2.8
m, with four rows per plot. The treatments were designed to study the effect of compost rates on the potato production and
soil fertility properties. Five rates of compost were investigated (control, 40, 80, 120 ton compost per hectare; and inorganic
fertilizers (250 kg N·ha−1, 250 kg P2O5·ha−1 and 300 kg K2O·ha−1)). Results of the first growing season 2006/2007 showed that marketable tuber yield, plant height and specific gravity were
greater in compost amended soil than in non-amended soil even if inorganic fertilizers were added. Application of 120 ton
compost per hectare gave the highest total tubers number, marketable tuber yield, height and specific gravity. |
