    Response of organic manures on growth, flowering and spike yield of tuberose (Polianthes tuberosa L)
    (CCSHAU, Hisar, 2021-08) Manisha; Beniwal, B. S.
    The present study entitled “Response of organic manures on growth, flowering and spike yield of tuberose (Polianthes tuberosa L.)” cv. Prajwal was carried out at Deen Dayal Upadhyay Centre of Excellence for Organic Farming, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2020-21. In this experiment, three sources of organic manures viz., FYM, vermicompost and poultry manure were taken along with their five levels (control, 2 Kg/m2 , 3 Kg/m2 , 4 Kg/m2 and 5 Kg/m2 ). This experiment comprising of fifteen treatments laid out in split plot design with three replications. The plot size was kept 1.5 m x 1.5 m with spacing 30 cm x 30 cm between row to row and plant to plant. Among the different organic manures vermicompost gave best results followed by poultry manure and FYM. Days taken to initiation of sprouting and complete sprouting were minimum with the application of poultry manure while early spike emergence, early opening of first floret, maximum plant height, length of leaves, number of leaves per clump, length of spike, length of rachis, stem diameter, number of florets per spike, spike weight, number of bulbs per clump, diameter of bulb, weight of bulb, spike longevity under field and vase conditions were observed when fertilized with vermicompost @ 4 Kg/m2 whereas maximum organic carbon in soil & potassium content in leaves and soil with the application of vermicompost @ 5 Kg/m2 . Nitrogen & Phosphorus content of plant and soil was observed maximum with poultry manure @ 5 Kg/m2 . Among microbial activities, dehydrogenase activity was maximum with FYM and alkaline phosphatase activity with poultry manure @ 5 Kg/m2
