                                    PRODUCTION TECHNOLOGY FOR SUGAR CROPS

               Sugar cane and sugar beet

               By product (leaves, top) are used for the preparation of paper and also use as feed for animals. By product
               (molasses) are used as alcohol and remaining part of molasses called bagasses. Most of sugarcane
               cultivars are male sterile and therefore they donot change into reproductive stage. But there are two areas
               jaban (dargai) and karachi where sugarcane reach to its reproductive stage. Sugar beet reprodcuting stage
               is called bolting stage which occur in second year which is undesirable because sugar content decreases.
