Abstract
A field experiment on “Standardization of fertilizer levels and placement of
emitters on growth, yield and quality of banana cv. Grand Naine at different plant
densities’’ was conducted at Horticulture Research Station, UAS, GKVK, Bengaluru,
during the year 2018-19 and 2019-20. In experiment one, plant height at shooting and
yield per hectare were registered significantly highest in treatment S1, F2 (1.5 x 1.5 m, 125
% RDF) whereas, the lowest was found in the treatment S3, F3 (2 x 2 m, 75 % RDF). Other
growth parameters viz., (pseudostem girth, number of leaves and leaf area per plant,
number of functional leaves at flowering and at harvesting, days taken from planting to
shooting, days taken from shooting to harvesting and days taken from planting to harvest)
were found significantly highest in the treatment S3, F2 (2 x 2 m, 125 % RDF). However
the lowest was observed in treatment S1, F1 (1.5 x 1.5 m, 75 % RDF). Quality parameters
like (total sugar, reducing sugar, non reducing sugar and total soluble solids) were also
registered highest in the same treatment S3, F2 (2 x 2 m, 125 % RDF). With respect to
experiment two the highest plant height and yield per hectare were registered in treatment
S1, E2 (1.5 x 1.5 m, placement of emitters at 40 cm) and the lowest was observed in the
treatment S3, E1 (2 x 2 m, placement of emitters at plain). Rest of growth parameters were
recorded highest in treatment S3, E2 (2 x 2 m, placement of emitters at 40 cm). Similarly
quality parameters were also registered highest in the treatment S3, E2 (2 x 2m, placement
of emitters at 40 cm) and the lowest was found in the treatment S1, E1 (1.5 x 1.5 m,
placement of emitters at plain). This was observed in plant crop (2018-19) and similar trend
was also noticed in ratoon crop (2019-20).
