Abstract
The choice of suitable cultivar(s), for a set of agro-climatic condition, is of paramount importance for its commercial profitability.
A number of ber cultivars have been recommended for cultivation in different parts of India but no such recommendation is available for West Bengal, an eastern state of the country.
Besides, most of the cultivars evaluation trials were conducted in a wide spaced orchard and on directly planted budded plants.
Due to modern urbanization, availability of cultivable or culturable wastelands are diminishing and technology development for vertical growth is now greatly needed.
Hence, a long term investigation was undertaken in a private orchard in Paschim Midnapore district of West Bengal, to find out the suitable cultivar(s) for close spaced orcharding under top-work system of raising.
Results from 5 years of investigation after top-working, indicated that the cultivar Jogia gave highest fruit yield of 72 kg/plant and estimated to have obtained 32 tonnes yield/hectare at a spacing of 5×4.5 m followed by Gola (54 kg/plant and 24 tonnes/ha). Fruit weight was highest in Jogia (30 g) and lowest in Ilachi (8 g). Natural fruit drop was highest in Kaithali (90%) and lowest in Gola (66%). The fruits of Ilachi having highest pulp content with maximum in Total Soluble Solids (21.1°B), sugar/acid ratio (54.2) and vitamin C (180 mg/100 g pulp). Fruits of Sanur-2 and Kaithali had maximum storage life (18 days) while Seb had the minimum under normal room temperature.
Ber titbits (salted) of Gola and Kaithali had the maximum storage life (180 days) in normal room temperature kept in closed glass jar.
A good number of cultivars showed resistance against powdery mildew under field condition.
