Effects of spacing on the growth and yield of Okra (Abelmochus esculentus) L. Moench in Obubra, Cross River state
Abstract
The effects of plant population on growth and yield of Okra (Abelmoschus esculentus L. Moench) was investigated for two planting seasons (2008 and 2009) in the teaching and research farm, Department of Agronomy,
Cross River University of Technology, Obubra . Treatments were five Okra plant populations : 111,111, 55,555,35,714, 27,77 and 23,810 Okra plants/ ha. High plant population significantly( P< 0.05) reduced number of leaf blades per plant, number of branches per plant and dry matter of plant fraction. The highest plant height of 1.01.3cm and leaf area index of 5.1 were obtained from plant population of 111, 111 plants/ha and this was significantly( P<0.05) higher than values obtained from others. The least plant population of 23,810 plant/ha produced more higher okra fresh pods and weight per pod and seeds per plant as compare with other higher plant population of 55, 555 and 35,714 Okra plants /ha. The highest Okra fresh pod yield of 7.36 and 7.43 tons/ha were obtained from plots treated with 111,111/ha during 2008 and 2009 planting seasons respectively ,The lowest yield values of 3.45 and 3’36 tons/ha were obtained from 23,810 okra plants/ha in the two planting seasons (2008 and2009)respectively.
