A comparative study on growth and nutritive value of Azolla pinneta and common duck weed (Lemna minor) under agro climatic condition of Assam

Azolla pinneta and common duckweed (Lemna minor) were cultured in concrete tanks separately under field conditions for 30 days, at the farm of Livestock Research Station, Assam Agricultural University, Mandira, Assam. The biomass production, doubling time and relative growth rate of A. pinneta was recorded as 173.33±13.16g, 5.55±2.35days and 0.124±0.35 g/g/d respectively and L. minor was 143±11.95g, 8.15±2.85 days and 0.084±0.28 g/g/d respectively. The values significantly (P
