Abstract:

The experiment was conducted during rabi season of 2015-16 and 2016-17 at District Seed Farm under Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal with a view to performance of rabi groundnut under polythene mulch and finally to validate the productivity enhancement through inoculation of newly isolated rhizobium. The design of the experiment was split plot with three replications. The main plot comprises viz., Mo: Without mulch; M1: With mulch and subplot treatment was nutrient management viz., F1: 100% RDN; F2: 75 % RDN; F3: 50 % RDN; F4: 100% RDN+ rhizobium; F5: 75% RDN+ rhizobium; F6: 50% RDN+ rhizobium; F7: Rhizobium. White, transparent 7 micron polythene was used as mulching. The newly isolated rhizobium strain was inoculated with groundnut variety TG51. Germination % was found maximum and days to germination were less under polythene mulch as compared to without mulch. Plant height increased steadily under both polythene mulching and soil application of inorganic fertilizer (100% of RDN) along with rhizobium. Dry matter production, CGR and number of nodules plant-1 were further influenced under inorganic fertilizer application to groundnut rather polythene mulch but it was further increased when rhizobium was supplemented with inorganic fertilizer. Polythene mulch had greater influence to increase the yield attributes and kernel yield of groundnut and significantly higher kernel yield was found under polythene mulch over without mulch. Incremental doses of soil application of inorganic nitrogen either 75% or100% of RDN gave the higher kernel yield as compared to 50 % of RDN. Higher BCR was found under polythene mulch treatment and 100 % RDN along with rhizobium. 25 % of soil application of inorganic nitrogen could be replaced by inclusion of location specific strain of a fresher rhizobium to achieve the optimum yield of groundnut kernel.
