Effect of Chlor-alkali solid waste effluent on 50 percent flowering of a little millet crop

K. L. Barik

Abstract :

<p>&nbsp;The little millet (Panicum sumatrense Rath ex. Roem and Schult) crop variety SS. 81-1, exposed to chlor-alkali solid waste effluent @ 100 g m-2 (treatment - 1),200 g m -2 (treatment - 2), 300 g m-2 (treatment - 3) and 400 g m-2 (treatment - 4) was studied in vivo at the Agriculture Research Station, Ankuspur in the District of Ganjam, Odisha at an interval of 15 days starting from 30 days after sowing (DAS) till harvest of the crop following the ICAR technology proposed by Seetharam (1994) with little modification depending upon the soil condition and climate of the locality. Days to 50 percent flowering did not show any variation. Plants in control and all treatments exhibited 50% flowering at 58 days after sowing. It indicates that the crop can tolerate the waste soil concentration applied in the soil. However, this concentration of chlor-alkali solid waste effluent used in field would vary from place to place and also from crop to crop because of soil quality and climatic variation of the place. Besides, the soil amendment practices with modern improved technology as well as the genetic set up of the crop might be responsible for detoxification of waste soil concentration applied in soil in some extent.</p>
