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. Harvesting data (i.e. on 87 days after showing) was considered for enumeration of productive panicle length and number of productive tiller. The length of productive panicle (cm) gradually increased from control to treatment-1, treatment-2 and then to treatment-3. Treatment-4 showed lower panicle length compared to treatment-3. The average number of productive tiller exhibited almost same in control and all treatments at the time of harvest (87DAS) of the crop. Variance analysis pertaining to length of productive panicle showed significant F values (p ≤ 0.05) whereas no significant variation was observed in case of number of productive tillers among the control and treatments exposed to various concentration of chlor-alkali solid waste effluent.
