What to do for good yield of maize?

Let's try to understand. If your maize crop starts getting blemishes or mocha, then keep moisture in the fields and use potash along with other fertilizers. Potash can also be given through spraying such as N. P.K. 13.0.45, i.e. 25 g. 5g with Nano-Red 15 L to Agvital. Dissolve it in water and spray it twice at an interval of 10 days.
