Lime Pulps from Arhar Sticks (Cajanus Sp.) and Jawar Stalks (Sorghum Sp.)

Laboratory experiments on the production of lime pulps suitable for strawboard manufacture from arhar sticks (Cajanus sp.) and jawar stalks (Sorghum sp.) are described. Arhar sticks give pulps of higher yield whereas the strength properties are better in the case of jawar pulps. The strength properties of board sheets in both the pulps are higher than prescribed in I.S.I. Standards for strawboards and the yields are in both cases higher than rice straw and wheat straw.
