Abstract
An investigation on “Fertilizer reduction techniques in cabbage (Brassica
oleracea var. capitata L.)” was carried out at Main Horticultural Research and
Extension Centre (MHREC), University of Horticultural Sciences, Bagalkot
(Karnataka) during rabi season of 2017-18. The field experiment was laid out in a
Randomized Complete Block Design (RCBD) with three replications consisting of
thirteen treatments.
The experimental results with respect to growth, yield, quality, economics and
nutrients uptake have significantly influenced by foliar fertilizer application at
different concentrations (2.5%, 5.0% and 7.5%) with minimum soil application of
RDF at different levels and crop growth stages (20, 40 and 60 DAT).
Among the different treatments , T9 (66 % RDF + 2.5 % FA) has proved most
beneficial as manifested in the maximum plant height (15.83 cm), number of loose
leaves per plant (15.85), leaf length (22.46 cm), leaf breadth (22.48 cm) and leaf area
(504.90 cm2). Further yield parameters like weight of individual head (0.96 kg), head
diameter (15.78 cm), total yield (54.09 t ha-1) and marketable yield (53.26 t ha-1)
were proved to be positively and significantly influenced by the treatments and also
Quality parameters viz., highest TSS (4.58o brix), ascorbic acid (53 mg/100 g), highest
dry matter of the head (7.20 g) and highest chlorophyll content (29 mg/100 g)
followed by T10 (66 % RDF + 5 % FA) were enhanced due to various treatments.
With respect to B: C ratio, T9 was found to be tremendously reduce the cost of
fertilizers (about 34 %) with highest net return (Rs. 2,67,484) as compared to T13
(Rs. 2,19,156).
It was concluded that T9 not only remunerative but also increases efficacy of
cabbage plant nutrient uptake and reduce the soil pollution Hence the foliar
fertilization is an important practice and novel measure for sustainable and succesful
cabbage production.
