PhD thesis
Potassium contributes significantly to growth, development, yield, and quality of the crop plants. Application of unbalanced potassium fertilization leads to low productivity and quality of cereals and other crops. Hence, there is an urgent demand to find out the balanced source of potassium fertilizer through utilization of nutrient management approaches. In the current study, we applied farmyard manure (FYM) as an alternative source of potassium fertilization, combination of FYM and muriate of potash (MOP) to show their role on growth, development, yield. Expression study of potassium transporter in corn (PEHM2 variety) also carried out. A field experiment was carried out using 0, 60, 90 kg K/ha through MOP, FYM and their combinations in corn-wheat cropping system during two consecutive years 2010-11 and 2011-12. Results showed that potassium fertilization played a significant role in the enhancement in growth and development of shoot as well as root. The high expression of ZmKUP gene, associated with translocation of potassium in plants with fertilization of potassium resulted in an improvement in growth and yield which further leads to an increase in yield of corn. Application of MOP and FYM both as potassium fertilizer showed a significant improvement in growth and yield of corn through an enhancement of ZmKUP expression. So, here we are showing that FYM as an alternative source of potassium fertilization as a suitable option for sustainable yield. |
