Growth and yield response of potato crop to different sources of potash

Potassium out of macronutrients is very important for potato plant, as it regulates growth and vigour, improves quality and general health that ultimately hastens yield. Potassium also keeps potato away from various physiological disorder and infections. Organic matter like farm yard manure (FYM) improves potassium uptake by potato plants. A research project was planned to investigate the influence of different potash sources and their combination with FYM for enhanced growth and yield of potato. Results revealed that parameters like days to emergence, total emergence percentage, mortality percentage and number of stems per plant were significantly affected by potash source sulphate of potash. While number of tubers per plant and number of compound leaves per plant were significantly affected by the combination of ½ Murate of potash and ½ FYM. Plant height was found highest by the application of FYM. The yield parameters were found significantly higher by the combination of ¼ MOP and ¾ FYM. Tuber dry weight remained highest by the application of MOP alone and total soluble solids (TSS) were found boosted by the combined effect of ½ SOP and ½ FYM. In this way it is concluded that potash fertilizers with FYM can be a good policy towards obtaining higher yields of potato crop.
