Influence of Fertigation, Microbial Consortium and Biostimulants on Bulb Yield of Tuberose (Polianthes Tuberosa L.) Cv. ‘Prajwal’

An experiment was conducted for two consecutive years during 2015-16 and 2016-17 at T. Pudhupatti village, Dindigul District of Tamil Nadu to study the influence of fertigation, microbial consortium and bio-stimulants on bulb yield of tuberose (Polianthes tuberosa L.) cv. ‘Prajwal’. The treatments consisted three levels (125, 100 and 75 per cent) of recommended dose of fertilizer through fertigation (RDFTF), microbial consortium (MC) of 12.5 kg ha-1, foliar spray of panchagavya (3 and 4 per cent) and humic acid (0.4 and 0.5 per cent). The results revealed that, 100 per cent recommended dose of fertilizer through fertigation + microbial consortium @ 12.5 kg ha-1 + panchagavya @ 3 per cent and humic acid @ 0.4 per cent recorded significantly higher number of bulbs, bulblets, length of bulb, diameter of bulb and bulb yield. Fertigation of recommended dose of fertilizer along with microbial consortium and foliar application of panchagavya and humic acid increased the bulb yield by 14 to 47 per cent, compared to the rest of the treatments. Therefore, an integrated approach with specific emphasis on fertigation, microbial consortium and biostimulants could be recommended for obtaining higher bulb yield in Tuberose.
