EFFECT OF CHLOR-ALKALI SOLID WASTE EFFLUENT ON NUMBER OF GREEN LEAVES OF A LITTLE MILLET CROP

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. The Number of green leaves per plant in control and treatments were counted and averaged. The number of green leaves per plant gradually increased from 30 days after sowing (DAS) to 45 DAS then to 60DAS and thereafter started decreasing till harvest (87DAS). Number of green leaves in control and treatments exhibited a trend of control < Treatment - 1 < Treatment – 2 < Treatment – 3 > Treatment -4 in most of the sampling periods.
