Abstract
A field experiment was conducted at Agronomy Field Unit, Zonal
Agricultural Research Station, University of Agricultural Sciences,
G.K.V.K., Bengaluru during Kharif, 2012 to study the effect of foliar
application of water soluble NPK fertilizer on growth, yield and quality of
lima bean (Phaseolus lunatus L.). The experiment was laid out in a
Randomized Complete Block Design with three replications and eight
treatments using a bush type lima bean variety. The results revealed that
application of 25:50:25 kg NPK ha-1 + foliar application of WSF (19:19:19
at 0.5%) at branching, 50% flowering and pod development stage (T8)
recorded significantly higher plant height (58.0cm), number of primary
branches plant-1 (9.3), leaf area (723 cm2 plant-1), number of pods plant-1
(63.97), 100 seed weight (39.3g) and seed yield plant-1 (37.3g) has
resulted in higher seed yield of 1408 kg ha-1 over control (1007kg ha-1).
Further significantly higher NPK uptake (80.38, 19.5 and 98.05 kg ha-1,
respectively) was recorded besides registering higher net returns
(Rs. 1,14,398 ha-1) and B:C (4.8) than all other treatments.
Among different RAPD markers used, OPG 09 and OPE 16 could
be used to identify the bush type lima bean from pole type.
