Effect of seeding method and fertilizer application on weed biomass and yield of wheat (Triticum aestivum)

Abstract

A field experiment was conducted on sandy loam soil analysing low in N and medium in P and K during rabi season of and at Varanasi to 1993-94 1994-95 evaluate the effect of different methods of sowing and fertilizer application in wheat (Triticum aestivum L. emend. Fiori & Paol.). Line sowing and placement of fertilizer in rows 5 cm below the seed showed significant reduction in weed biomass and increased the yield of wheat over broadcast sowing and fertilizer application. Seed emergence was markedly reduced when fertilizer and seed were mixed and then sown in rows. The root weight of plants grown with broadcast sowing was lower than of row sown crop. The row sowing of seed and placement of fertilizer in rows or broadcast of fertilizer but sowing of seed in rows removed higher amount of N, P and K than broadcast of seed and fertilizers.
