THE RESPONSE OF LIGNITE FLYASH, A BY PRODUCT OF THERMAL UNIT ON YIELD AND YIELD ATTRIBUTES OF SUNFLOWER

Abstract :

Investigations were carried out with four levels of lignite flyash viz.,5, 10,15, and 20t ha⁻¹ with or without pressmud an agro industrial by product with the objective of studying their influence on sunflower during 2010 (Rabi) and 2011(Summer). This study revealed that lignite flyash @ 5t ha⁻¹ with pressmud exerted a remarkable influence on all the yield attributes. It significantly recorded the highest values of plant height (148 cm),capitulam diameter(19.1cm) and seed yield(1994kg ha⁻¹ ). With regard to sole application of lignite flyash, LFA @ 5t ha⁻¹ registered significantly the highest values in plant height (89cm), capitulam diameter (16cm) and seed yield (1415kg ha⁻¹). The same trend was followed in 2011, summer also. From this study it was concluded that application of LFA @ 5t ha⁻¹ with pressmud and RDF enhanced the grain yield in sun flower.
