Effect of zinc in combination with lime on the growth and yield of rice

Abstract

A pot culture experiment was carried out using the Vellayani Kayal soil in a randomized block design to study the effect of zinc in combination with lime on the growth and yield of rice. The number of tillers per plant was increased significantly by lime, but not by zinc. Neither lime, nor zinc had any significant effect on the number of productive tillers, whereas these treatments resulted in significant increase in the height of plants. The panicle length was increased significantly by lime and the number of grains per panicle was increased by both lime and zinc. The effect of zinc on the yield of grain and straw was inconsistent whereas the yield of grain tended to increase with increase in the levels of lime.
