Abstract:

Jute fibre producing states are completely dependent for its most vital critical input i.e., seed on import from South and West Indian states of India like Maharastra, Andhra Pradesh, Telengana and Karnataka. For self-sufficiency, jute seed production potential of irrigated midlands (0-30 ponding) were tested by developing shallow ridges (15 cm high and base width 50 cm) on puddled rice soil from Mid-August to January. Scanty rainfall coupled with cool and dry weather from November to January has opened up a new vista for jute seed production in traditional jute fibre producing areas of Eastern India. Jute seed production was recorded highest (635.83 kg/ha) using N:P2O5:K2O::60:40:40 kg/ha (Recommended Dose of Fertiliser, RDF) along with bone meal 1.0 t/ha (23% more over control). In control (RDF) the jute seed production potential was only 518.33 kg/ha. The RDF along with jute leaf manure @ 0.5 t/ha produced 542 Kg jute seed/ha (5% more over control). Combination of recommended fertiliser and Neem cake @ 0.2 t/ha produced 580 kg jute seed/ha (11.89% more over control). Amongst sole chemical fertiliser treatments, treatment T3 (N:P2O5: K2O:: 100:40:40) produced 579.17 kg jute seed /ha (12% more than RDF). Thus, 3.1 to 3.8 kg jute seed can be harvested from 1.5 cent (60 m2) rice midlands, which is sufficient enough to meet the jute seed requirement of one hectare area, using jute seed drill or jute sowing by regulated broadcast method. Incidentally more than 80% of jute farmers are small and marginal in nature and they grow jute in less than one hectare area. RDF+ jute leaf manures @ 0.5 to 1.0 t/ha recorded higher net returns (` 28600 to ` 32800/ha) owing to its low cost of production and relatively higher seed yield over RDF alone in both the years with higher B:C ratio from 1.56 to 1.63. Application of augmented chemical fertilization T2, N:P2O5:K2O::80:40:40 kg/ha fetched higher net returns (` 30560 to ` 36510/ha) and B: C ratio from 1.58 to 1.70. Thus judicious management can achieve jute seed production in Eastern India and Bangladesh.
