Potential of Dual-Purpose Organic Amendment for Enhancing Tomato (Lycopersicon esculentum M.) Performance and Mitigating Seedling Damage by Mole Cricket (Gryllotalpa africana spp.)
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 20, Issue 6
Abstract
Aim: Efficacy of locally produced dual-purpose organic amendment for improving tomato protection and yield was compared with synthetic pesticides and fertilizers. Methodology: The experiment was setup as randomized complete block with three treatments (control, inorganic and organic) each replicated four times. Results: Treatment was negatively correlated with tomato seedling damage by mole cricket (r = −0.86), with 100% efficacy in the organic treatment compared to 90% in the inorganic treatment and 80% in the control (P = .05). Treatment was negatively correlated with tomato blight (r = −0.57), with 100% blight infestation in the control compared to 8% in the inorganic treatment and 25% in the organic treatment (P = .05). No tomato plant was damaged in the organic treatment, compared to 12.5% in the inorganic treatment and 29.1% in the control (P = .001). The total plant damage was negatively correlated with treatment (r = −0.97) and positively correlated with seedling damage (r = 0.90), blight (r = 0.57) and wilt (r = 0.97). The highest tomato yield occurred in the inorganic treatment with 43.9 t ha-1 and organic treatment with 38.1 t ha-1, which differed (P = .05) significantly from the control with 1.5 t ha-1. Tomato yield correlated positively with the number of leaves per plant (r = 0.66), but was negatively correlated with blight (r = −0.70) and wilt (r = −0.60). The highest number of leaves per plant was recorded in inorganic treatment with 30 and organic treatment with 28, compared to 15 in the control (P = .05). Treatment was positively correlated with number leaves per plant (r = 0.63), while the number of leaves was negatively correlated with blight incidence (r = −0.92). Conclusion: The dual-purpose organic amendment is an effective sustainable alternative for improving tomato protection and yield compared to inorganic inputs.
