TAILIEUCHUNG - Effect of pinching height on growth, fruit and seed yields of tomato (Lycopersicon lycopersicum Mill.)

The field experiment was conducted at the Teaching and Research farm of Niger State College of Agriculture, Mokwa during 2010 and 2011 cropping seasons (9o 181N and 5o 041E) with altitude of m above the sea level in the Southern Guinea Savanna region of Nigeria to assess the effect of pinching height on growth, fruit and seed yields of tomato (Lycopersicon lycopersicum Mill). Treatments consisted of two varieties (Ibadan Local and Ife 1) and four levels of pinching. Farmers’ normal practice (1), pinching height at 30 cm (2), pinching height at 50 cm (3) and pinching height at 60 cm (4). The experiment was factorial layout fitted into Randomized Complete Block Design (RCBD), replicated three times. Harvesting was done when 85% of the fruits had turned yellowish. Data were taken on plant height per plant, number of flowers per plant, number of fruits per plant, fruit yield t/ha. Other parameters included number of rotten fruit per plant, seed yield (kg/ha) and 100 – seed weight. Data collected were subjected to analysis of variance (ANOVA) using Minitab 15 software and means were separated using (NDMRT). The result showed that number of fruits, fruit and seed yields were greater in Ibadan Local than the other variety. Plants pinched at 50 cm height had the highest fruit yield and pinching at 30 cm height gave the best seed yield. | Effect of pinching height on growth, fruit and seed yields of tomato (Lycopersicon lycopersicum Mill.)
