A scientific paper by W. Lawrence Balls, Part III of his series on analyzing agricultural yield, studying how environmental factors such as water-table, soil fertility, soil depth, temperature, sowing date and variety affect flowering and bolling in Egyptian cotton. It draws on field experiments at Giza (the Terraces, 1909-1911, and spacing and sowing-date trials, 1912-1913), Talbia, Gemmaiza, Salaka, Mit Khalaf and Neguila. It discusses how daily flowering fluctuations can be pre-determined from main-stem and branch growth, and how a rising water-table curtails flowering. It includes many flowering-curve graphs and an appendix of data tables.
