you mentioned experiments what else have you learnt about other kinds of plants and vegetables in your experiments
i noticed that a few of corn plants have top tassels were purple what does that mean (just a few of many) but i applied some urea and its starting to perk up a little
I read online purple color means soil has a shortage of something that can be corrected with fertilizer. I had several purple colors this year on the north west part of the corn crop. There are lots of trace elements in wood ash I burn old lumber & tree limbs I save the wood ash in 5 gallon buckets. Corn is a very heavy feeder it uses up all of the K in the soil that causes purple color. K shortage causes sugar in corn leaves to not be able to move to the ears & kernels. This year when I saw purple color I did Google search then gave my plants 15-15-15 fertilizer and wood ash in the area where plants are purple color. I decided to do the same thing to the rest of the corn it might turn purple too if I don't. This year corn was exceptionally good year for corn I think it was because we had rain several times at the correct time corn needed rain.
We usually only have 1 small rain every month June to Oct corn is often small. In the past I also grew 72 day corn this year I grew 90 day corn. 90 day corn ears & kernels are 2 times larger than 72 day corn it takes 250 ears of 72 corn to equal 150 ears of 90 day corn. G-90 corn that I grew this ears is better suited for hot weather. 40 years ago we grew yellow corn then we tried white silver queen we grew that for 20 years now we like bicolor corn I have tried several bicolor corn so far G90 is the best & flavor is just as good as Peaches & Cream corn. I tried 2 different kinds of SUPER sweet, sweet corn germination in only 50% to 60% I learned to plant 6 rows of corn then transplant corn to 3 rows to fill in the blank spots. Transplant 150 corn plants 1 shovel of soil each time is too much work. Last year I did not transplant corn we had 6 rows over very spotty corn that wasted a lot of garden space.
Next year I will only plant 3 rows of G90 corn 50 plants per 34 foot long row and hope for the best. If I am forced to water plants 150 plants will won't a big job like 500 plants we had this year. I did over kill this year to make sure we finally got a very good crop and we had corn to give away. If my garden space was bigger I could afford to plants several types of sweet corn all in the same season to learn what works best in our crazy 100° hot blistering summer heat with no rain.
Years ago when we lived in a different house my garden was much smaller than what we have now. I use to plant 10 rows of corn in a 10' x 10' crop. I planted 10 rows of corn with rows spaced 12" apart with seed spacing 6" apart. 200 corn plants in a 10 ft square crop. Corn planted this close together I could not weed with the tiller only things I could do was with weed from all 4 sides with the hoe. Corn crop was extremely easy to grow that small and we always had a very good harvest.
