Evaluation of the effects of some soil amendments on the agronomic performance of snake tomato in a newly established rubber plantation in iyanomo

A field study was conducted in 2018 and 2019 cropping season to determine the comparative effects of some soil amendments on the growth and fruit yield of snake tomato in a newly established rubber plantation in Iyanomo. The treatments involved a combination of sole and intercropped combination with NPK and rubber effluent application rates laid out in a randomized complete block design in three replications. Data were collected on vine length, vine girth, number of leaves, leaf area, fruit yield and its components. Results showed that soil amendment had significant effect on growth and fruit yield of snake tomato (P<0.05). Soil amendment significantly (P<0.05) improved snake tomato growth characters. The fertilized plants were higher in all the characters accessed than the unfertilized plants. Sole and intercropped snake tomato fruit yield with or without treatments had similar values. Unfertilized sole and intercropped snake tomato had the lowest fruit yield. The highest fruit yield were obtained from sole and intercropped snake tomato treated with NPK (STNPK and RSNPK).
