Beginner Gardening: Still no signs of corn after 3.5 months??, 0 by growingup

I planted sweet corn in the beginning of March. It took 3 weeks or so before it would even sprout. Now it has grown significantly, but still no signs of corn. The tassels are emerging so that is a good sign. Anyone know what my problem could be? I'm thinking fertilizer? I live in Tucson zone 8a and it is over 100* everyday. I have my drip system hooked up to quarter inch soakers and there is a soaker for every row of my garden. It comes on 3 times a day for 15 minutes. I'm thinking I might need to have it come on for 30 minutes instead of 15. Anything else I can do? Also, my corn is very close together. Should I pull some to make room, if so, how much room should be between stalks? Thanks:)
