Abstract
The field investigation on influence of micronutrients as foliar spray on growth,
yield and quality of pole bean (var: Suvarna) under open field and protected conditions
was undertaken at the Department of Horticulture, UAS, GKVK, Bengaluru. The highest
vine length (334.0 cm), number of leaves plant⁻¹ (253.99), chlorophyll content (61.37),
higher number of pods plant⁻¹ (158.61), pod length (19.72 cm), pod width (8.85 mm),
higher protein content (24.54 %), higher pod yield plant⁻¹ and hectare-1
(1.46 kg and
59.00 t respectively) were recorded significantly with spray of Zn 0.5%+B 0.25%+ Fe
0.25% under protected condition. Similarly, under open field condition, higher vine
length (271.00 cm), number of leaves plant⁻¹ (224.47), chlorophyll content (59.27),
higher number of pods plant⁻¹ (144.60), higher pod length (18.66 cm), pod width (8.71
mm), higher protein content (23.71%) and higher pod yield plant⁻¹ and hectare-1
(1.02 kg
and 40.89 t respectively) were noticed with spray of Zn 0.5%+B 0.25%+ Fe 0.25%.
Similarly, the highest estimated pod yield per hectare (59.00 t ha⁻¹) and higher net returns
(Rs.12,49,668 /-) and higher cost benefit ratio (1:3.4) was recorded with the same
treatment under protected condition. In general, better vegetative growth, higher yields,
good quality pods and higher net returns were obtained in pole bean grown under from
protected conditions compared to open-field condition.
