Title: Productivity of Sesame (Sesamum indicum L.) Varieties as Influenced by Seed Rate.
Abstract: A field trial was conducted during the dry season of 2013 at the Institute for Agricultural Research Institute (IAR) farm at Samaru latitude (11 o 11n, Longitude 7 o 38E and 686m above sea levels in the Northern Guinea Savannah) Ecological zone of Nigeria. The treatments consisted of three sesame varieties (E8, Pbtil, and Ex-Sudan) and three seed rates 2.0, 3.5, and 5.0kg/ha. The treatments were arranged in a Randomized Complete Block Design (RCBD) with three replications. The results showed that increase in seed rate from 2.0 to 5.0kg/ha decrease plant height, number of branches, and total dry matter per plant. A similar trend was observed for number of capsules, and grain yield per plant. However, grain yield per hectare was found to have increased with an increase in seed rate up to 3.5kg/ha. Further increases beyond this decrease the grain yield per hectare. The results further showed that Pbtil produced significantly taller plants but showed a decreased number of branches and total dry matter compared to E8 and Ex-Sudan. The variety, ExSudan, produced significantly higher number of capsules, grain yield per plant and grain yield per hectare compared to E8, which in turn performed better than Pbtil in these characters. Based on the results obtained in this trial, it can be concluded that Ex-Sudan planted at seed rate of 3.5kg/ha gave the highest grain yield of sesame; it is therefore more suited to Samaru ecology.
