Effect of Magnetized Water and Seeds on the Growth and Yield of Sesame (Sesamum indicum L.) under Irrigation

Abstract

Magnetic treatment is hypothesized to result in the
improvement of the performance of some crops. A field study was
conducted to evaluate the effect of magnetized water and seeds on growth
and yield of sesame (cv. Promo). An experiment was carried out for two
consecutive seasons (2004/05 and 2005/06) in the Demonstration Farm,
Faculty of Agriculture, Shambat, Sudan. The seeds were either sown
directly or after passing them through a magnetic field. The crop received
equal quantities of either normal or magnetized water every 14 days. The
results showed that magnetized water and seeds consistently had non-
significant positive effect on mean plant height, number of leaves per
plant and stem diameter. The plants irrigated with magnetized water took
significantly fewer days to flower than their respective untreated plants.
Magnetized water and seeds significantly increased seed yield due to
increased number of capsules per plant. In contrast, all treatments had no
significant effect on mean 1000-seed weight and oil content of seeds.
