Abstract:

Field experiments were conducted at Instructional farm of Department of Vegetable Science, UBK, West Bengal. The study was aimed to evaluate about the effect of different combinations of organic nutrient sources and bio mulches on growth, physiology and yield of okra (cv. Arka Anamika) in the year 2017 and 2018. The experiment was carried out in Randomized Block Design (RBD) with three replications. There were two factors of the experiment such as factor N- Organic nutrient sources and factor M – Bio-mulches, each having four levels. The different levels were under factor N were (N1 –Farmyard manure (25 t/ha) + Azophos biofertiliser +Humic Acid; N2 –Farmyard manure (25 t/ha) + Azophos biofertiliser + Seaweed extract; N3–Vermicompost (5 t/ha) + Azophos biofertiliser + Humic acid; N4 - Vermicompost (5 t/ha) + Azophos biofertiliser +Seaweed extract) and under factor M (M1 - Rice Straw; M2- Dry water hyacinth (Eichhornia crassipes); M3- Dry local weed (Polygonum persicaria); M4- Dry vegetable legume plant residues) which in total comprises of 16 treatment and combinations. Random samples were collected and analysed at various growth phases. The results of the experiment revealed that application of biofertiliser enriched vermicompost with three time foliar spray of seaweed extract @ 2ml/lit at 30, 40 and 50 days after sowing along with dry vegetable legume plant residue (N4M4) exhibited maximum height (65.85 cm at 60 DAS), leaf chlorophyll content (41.91 SPAD value), total yield per hectare (16.65 t/ hectare) in pooled. However there was significant effect of different treatment combinations in growth, yield and physiological attributes of okra.
