Effect of different spacings on growth and yield of lima bean (Phaseolus lunatus L.)

Abstract

A field experiment was conducted at Main Garden, Department of Horticulture, Dr. P.D.K.V. Akola during 2015-2016 to study the influence of seven different spacing i.e. 0.75m x 0.75m.1.0m x 0.5m, 1.0m x 0.75m, 1.0m x 1.0m, 1.5m x 0.5m, 1.5m x 0.75m and 1.5m x 1.0m on growth and yield of lima bean. The results revealed that all the growth and yield parameters were significantly influenced by various spacing. The growth parameters like plant height, length of primary branch, length of secondary branch was found to be maximum in spacing 0.75m x 0.75m whereas trifoliate leaves per plant, primary branches per plant, secondary branches per plant and leaf area was obtained maximum in the spacing 1.5mx 1.0m. As regards the yield and yield contributing parameters number of pods per cluster, length of pod, width of pod, seeds per pod, weight of fresh pod, weight of fresh seed, weight of dry seed, weight of dry seed per pod, weight of 100 dry seeds, seed yield per plant and seed yield per hectare were found to be significantly maximum in the plant spacing of 1.0m x 0.75m.
