Impact of Organic Wastes (Bagasse Ash) on the Yield of Wheat (Triticum aestivum L.) in a Calcareous Soil

ABSTRACT Impact of various rates of bagasse ash on Wheat (Triticum aestivum L.) in a calcareous soil was studied in a field experiment. It was applied @ 0.1, 0.5, 1.0, 2.0, 5.0 and 10 % along with a basal dose of 120, 90, and 60 kg ha -1 of NPK. From the soil analysis, before sowing it was concluded that the soil under discussion was calcareous having 16.3 % CaCO 3 . The results showed that yield and yield components of wheat increased significantly with various rates of bagasse ash over control. However, significantly maximum plant height (102.8 cm), spike length (11.0 cm), number of productive tillers m -2 (333.5), number of grains spike -1 (49.5) and grain yield (5.2 t ha ) was significantly higher with 10.0 % bagasse ash and 1000-grain weight (41.20 g) with 1.0 % bagasse ash. The overall response of wheat crop was significantly higher by the application of bagasse ash @ 2.0 % to the calcareous soil
