PERFORMANCE OF AGRO INDUSTRIAL WASTES UNDER DIFFERENT LEVELS ON GROWTH AND YIELD ATTRIBUTES OF MAIZE (GANGA 5)

D.kumari Mani Muthu Veeral

Abstract


Field experiments were conducted to evaluate the effects of lignite flyash at four levels viz., 10, 15, and 20t ha⁻¹ with or
without pressmud, an agro industrial by product and RDF on Maize for consecutively four years during 2012-16. Lignite
flyash @ 10t ha⁻¹ with pressmud exerted a remarkable influence on all the yield attributes, ultimately leading to increased grain yield of 42.5
percent over control. With regard to sole application of lignite flyash, LFA @ 5t ha⁻¹ registered significantly the highest values in plant
height(89cm), LAI (4.3),DMP (61.0g pl⁻¹),cob length (15.4cm) cob diameter (5cm), grain number cob⁻¹ (340.5) and grain yield (5100 kg ha⁻¹).
From this study it was concluded that application of LFA @ 10t ha⁻¹ with pressmud and RDF enhanced the grain yield in maize.
