A promising approach to recycle the residual distillery waste as a potential liquid fertilizer has been discussed in this paper. Field studies were conducted on Brassica compestris to assess the potential of the diluted post- methanated distillery effluent. The results indicated that there was not much variation in pH, conductivity and nitrate of soil, whereas total dissolved solids, conductivity, nitrate and chemical oxygen demand of the well water increased slightly but well within the permissible limit. However, there was a significant increase in the plant biomass, diameter of the shoot and root, area of leaf, as well as number and length of pods and root hairs. The hydrophilic colloids of the seed increased significantly (p < .01) and the yield of mustard seeds was increased by 30% as compared to the conventional fertilizer. The carbohydrate, chlorophyll and ascorbic acid content of the leaf, stem and root were also analysed and its morpho- physiological significance is also presented in this paper.

With the growing importance of transmitting data over the network, data encryption is becoming critical. Encryption helps safeguarding the data transmitted over the network from an unwanted entity. The two methods to encrypt data are-Substitution and Transposition. Transposition refers to changing the position of characters in a given text. On the other hand, substitution is the process of replacing each character of the plaintext with some other character. Playfair cipher is an illustration of substitution cipher. The classical playfair cipher has a 5x5 matrix. To increase the resistance of playfair cipher, this paper proposes to introduce double Myszkowski transposition on a modified 6x6 playfair matrix. The 6x6 matrix includes the all the alphabets along with the single digit numbers. A comparison with the classical 5x5 playfair cipher proves the enhanced security of the proposed algorithm.
