COMPARATIVE EFFECTS OF ARBUSCULAR MYCORRHIZAL AND DEGRADED SAWDUST ON GROWTH AND YIELD CHARACTER OF PEPPER (CAPSICUM SPP)

Abstract

The experiment was conducted to evaluate the effect of Arbuscular mycorrhiza  and degraded sawdust on growth and yield characters of bell pepper (Capsicum annum L.)  The experiment was 2x4 factorial arranged in a Completely Randomized Design (CRD)) with four replicates. The eight treatments were combinations of two early maturing varieties of bell peppers (PEP and Gombe) and soil amendments (degraded sawdust, Glomus etunicatum and steam sterilized homogenous soil as control (C). The two varieties of bell pepper differed significantly in growth and fruit parameters. Variety Gombe had higher plant  height (22.2cm) and produced more fruits of bell pepper (1.7) than variety PEP inspite of its larger leaf area (23.1cm²) by the latter. The results also showed that soil amendment with degraded sawdust alone and combination with Glomus etunicatum improved the growth parameters such as plant height, stem girth, leaf area as well as numbers of flowers and fruits of bell pepper. The interaction of pepper and soil amendments was significant on all the growth and yield parameters with varieties exhibiting differential reactions to the soil amendment treatments. Soil amendments with degraded sawdust and combination of degraded sawdust with Arbuscular mycorrhiza  had positive effects on the growth and yield characters of both varieties of pepper used (PEP and Gombe).
