I recently conducted an experiment to test how much sunlight would be best for growing watermelon plants. I planted 50 watermelon seeds. 10 in a shady spot, 10 in a spot that receives two hours of sunlight a day, 10 in a spot that receives 4 hours of sunlight a day, 10 in a spot that receives 6 hours of sunlight a day and 10 in a spot that receives 8 hours of sunlight a day. All plants were given equal amounts of soil, water and fertilizer and were protected from bugs and other pests. At the end of the experiment I counted the number of watermelons grown in each plot.
