Brassica alba, one of the very anciently well known plants, was used as biofertilizer long time before. Pot culture technique was introduced and three different pots were prepared. Plants of first pot provided only normal dose of urea, in second pot additionally 10% B. alba liquid manure sprayed along with the normal dose of urea. Third pot was provided with blue green algal fertilization and 10% of B. alba liquid manure. Various parameters like plant height, leaf length, leaf number and inflorescence length were evaluated in test culture receiving different
dose of urea and bio-fertilizer. In pot-1, plant height, length of inflorescence, grain yield , husk yield , grains per panicle , number of panicle per plant and weight of 1000 grains was found to be 84.30 cm, 19.50 cm, 2800 kgha-1, 4300 kgha-1, 42 grains per panicle, 4 panicle and 24.80 gm respectively, whereas in pot-2 plant height, length of inflorescence, grain yield, husk yield, grains per panicle, number of panicle per plant and weight of 1000 grains was found to be 98.50 cm, 21.40 cm, 3700 kgha-1 ,5600 kgha-1, 56 grains, 6 panicle and 29.30 gm respectively and in test pot-3, plant height, length of inflorescence, grain yield, husk yield, grains per panicle, number of panicle per plant and weight of 1000 grains was found to be 112.80 cm, 24.30 cm, 3850 kg ha-1, 5630 kgha-1, 60 grain per panicle, 6 panicle, and 30.60 gm respectively. The results clearly indicated that in comparison to urea, B. alba treated paddy plant performed higher plant height, higher yield production, higher husk production, larger number of grain per panicle and panicle length and higher grain weight.
