Effect of sulphur and zinc on yield and quality of grasses grown in silvi-pastoral system of agro forestry in various seasons

Abstract

In many sodic soils sodicity originates from the nature of the parent material and pedogenic processes. There are also sodic soils where sodicity arises from anthropogenic processes (human activity), and this is termed secondary sodification. Irrigation with sodic water or without proper drainage, forest clearing, and other land management practices that lead to water logging are key activities that may yield rapid secondary sodification. The experiment was carried out during 2011-2012 in Dalbergia sissoo based silvipastoral system raised on sodic waste land at Main experiment station Forestry of Narendra Deva university of Agriculture and Technology, Kumarganj Ayodhya (U.P). Based on the result obtained from the present investigation, it may be concluded that Sulphur application @ 60 kg ha-1 and zinc @ 15 kg ha-1 was found most effective for tree growth characters increment of tree height, dbh, canopy, length and width of Dalbergia sissoo. Plant height of grasses Pennisetum purpureum, Brachiaria mutica, Penicum maximum, number of tillers hills-1 with high chlorophyll and protein contents in grasses.
