Abstract

A field experiment was conducted at Karnal during rainy season of 2012 to study the effect of nitrogen, phosphorus and zinc on growth, yield and economics of teosinte (Zea mexicana L.) fodder. Plant height, plant girth, number of leaves, leaf area index, number of tillers and branches increased with increase in levels of nitrogen, phosphorus and zinc. Green and dry fodder yield and gross returns, net returns and benefit: cost ratio increased significantly upto 160 kg N/ha, 40 kg P2O5/ha and 30 kg Zinc sulphate/ha. The treatment combination of N160 kg/ha, P2O5 40kg/ha and Zinc sulphate 30 kg/ha estimated as advantageous for production of teosinte fodder.
