Abstract

An investigation was conducted to determine the effectiveness of a new formulation of triacontanol on the growth, water content, yield, early maturity, total number of fruits, fruit and leaf dry weight and the concentration of N, P, K, Ca, Mg, Zn, Cu and Fe in the leaves of Tabasco pepper plants (Capsicum frutescens L.) grown on olivier silt loam. In the greenhouse experiment, 0.01 mg per liter of triacontanol applied at the rate of 15 ml and 10 ml to each Tabasco pepper seedling 18 and 43 days after planting, significantly increased the plant height and water content of 71 day old Tabasco pepper seedlings. Triacontanol at 0.001 mg per liter applied at the rate of 15 and 10 ml per container 11 and 46 days after planting significantly increased the dry weight of 118 day old rice (Oryza sativa L.) var. Saturn. The 1.25 mg per liter treatment of triacontanol applied at the rate of 15 ml and 10 ml 11 and 46 days after planting significantly increased the height of 118 day old rice (Oryza sativa L.). The 1.25 mg per liter of triacontanol applied at the rate of 25 ml per plant at transplanting significantly increased early maturity, total yield and the total number of fruits of Tabasco pepper grown in the field during the first summer. In the following summer the 1.25 mg per liter of triacontanol applied at the rate of 25 ml per plant at the time of transplanting and again at first bloom significantly increased early maturity, total yield, total number of fruits, height and diameter of Tabasco pepper plants. Fish wash, 454 grams of Mackerel head soaked and washed in 2 liters of distilled water for 15 minutes, applied at the rate of 50 ml per plant at the time of transplanting in the field during the first summer significantly increased early maturity, total yield, plant diameter and total number of fruits of Tabasco pepper. Similar results were obtained when 50 ml of fish wash were applied at the time of transplanting and again at first bloom in the following summer.
