Field studies were conducted at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria, to compare the plant population estimates by physical counting and by using existing mathematical formula, on sole crop fields of tomato (Lycopersicon esculentum (L.) Mil.), amaranth (Amaranthus cruentus L.), cock`s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). Each crop was established on a 5x10 m (50 m2) plot and sowing was done at one plant per stand. The planting spacing used were 50x50 cm, 20x20 cm, 20x20 cm and 1.0x1.0 m for L. esculentum, A. cruentus, C. argentea and T. cucumerina, respectively. Results showed that there was a significant difference between the estimate by physical counting and estimation by the existing mathematical formula. On the basis of the variation observed in the plant population estimation by physical counting and existing mathematical formula, a new formula was developed. The formula is flexible and can be used for direct estimation of plant population in any given four dimensional fields of sole crop. The optimization analysis of the farm field was also considered. |
