Growth and yield response to plant density of water leaf (Talinum triangulare Jacq.) in rivers state, Nigeria
The effects of different planting spaces (15cm x 15cm, 20cm x 20cm, 25cm x 25cm and 30cm x 30cm) on the growth and yield of Talinum triangulare (Water leaf) were investigated in two cropping seasons from 2012 to 2013 (rainy and dry seasons) at University of Port Harcourt Teaching and Research farm, Port Harcourt, Rivers State. A completely randomized block design was used in the experiment and the results were statistically assessed by analyses of variance. The results showed that the planting space of 15cm x 15cm recorded the highest plant height of 33.50cm in rainy season and 32.11cm in dry season. On yield per hectare, the spacing with 15cm x 15cm gave the significant yield of 14.47Kg and 10.01Kg in rainy and dry season respectively at seven (7) weeks harvesting after planting. This result showed that the planting space of 15cm x 15cm could be used to produce a higher yield of water leaf for consumption. Further research work on the use of different soil amendment materials to enhance productivity of the crop is hereby recommended.
