Abstract
Under arid and semiarid climate conditions, application of muriate of potash (KCl) results in salinity problem due to its higher chloride (Cl -) contents. In order to combat this problem, KCl was blended with different sources of compost (fruits and vegetables, poultry, press mud and cow dung) in order to get a dilution effect of composts. A pot experiment was conducted to evaluate the comparative efficacy of KCl blended composts and KCl or K2SO4 alone on growth, physiology and K nutrition of maize. Different composts applied @ 500 kg ha -1 were blended with KCl in such a way that each combination received the same amount of K as in case of recommended KCl and K2SO4 alone. Muriate of potash blended poultry compost significantly improved various growth parameters like plant height (19%), root length (60%), root (100%) and shoot fresh weight (64%), root (88%) and shoot dry weight (81%) and chlorophyll contents (29%) compared to KCl alone. However, the maximum physiological parameters were observed with KCl blended press mud compost. Similarly, KCl blended poultry compost significantly increased K concentration and uptake in shoot (26 and 122%) and root (39 and 133%) compared to KCl alone. Post-harvest soil analysis showed an increase of about 2 folds in K contents in KCl blended poultry compost compared to KCl alone. Based on the above results, KCl blended composts proved better in improving various growth, physiological and K nutrition of maize compared to the application of KCl and K2SO4 alone.
