A laboratory experiment were undertaken to study effect of potassium humate and deproteinised Juice (DPJ) of Lucerne and Fenugreek on seed germination and seedling growth of wheat (Triticum aestivum L.) cv. Lokvan and jowar (Sorghum vulgare L.) cv. Local. Seeds of wheat and jowar were treated with potassium humate (1.0%), either alone or in combination with deproteinised leaf juice (DPJ) of Lucerne and Fenugreek and water served as control. Seeds were then sown on moist blotter papers and percent seed germination (%) and seedling growth (root length and shoot length) of wheat and jower were recorded at the end of tenth day. Results obtained during this investigation clearly indicated that DPJ with potassium humate treated crop plants showed significant increase on seed germination and seedling growth of wheat and jowar than either potassium humate (1.0%), DPJ or control (untreated).
