    Response of okra (Abelmoschus esculentus L. Moench) to drip Irrigation, fertigation under different mulch conditions
    (Punjab Agricultural University, Ludhiana, 2023) Arshdeep Singh; Pathak, Mamta
    The present investigation was conducted at Department of Soil and Water Engineering Farm and Biochemical Laboratory, Department of Vegetable Science, Punjab Agricultural University, Ludhiana with the objectives to determine the yield, economic viability and optimum moisture regime under different mulch, fertigation and drip irrigation system in okra. Okra variety Punjab Suhawani was used as experimental plant material. The treatments included three levels of drip irrigation regimes i.e. at 100 per cent crop evapotranspiration ETc (I1), 80 per cent ETc (I2) and 60 per cent ETc (I3) along with three mulch treatment of silver polythene mulch (M1), straw mulch (M2) and non mulch (M3) under main plot treatments and three level of fertigation i.e. 100 per cent recommended dose of fertilizer (RDF) (F1), 80 per cent RDF (F2) and 60 per cent RDF (F3) was considered under sub plot treatment. Therefore, 27 treatments combinations including control were tested in the present study. Data of present study depicted the best results for combination of drip irrigation at 100 per cent ETc (I1), RDF 100 per cent (F1) and silver polythene mulch (M1) for 50 per cent germination (6.83 days), length of main shoot at 30, 60 and 90 days after seed sowing was 17 cm, 50.78 cm and 90.93 cm respectively. Number of branches 30, 60 and 90 days after seed sowing were 6.95, 10.58 and 14.56 respectively. Whereas, number of fruits per plant (12.43), average fruit weight (10.56), yield (199.89 q) and marketable yield was 191.62 q/ha. Total yield was recorded 39.77 per cent higher than I3M3F3 treatment combination. All quality parameters vitamin C (54.88 mg/100 g), chlorophyll (8.30 per cent), fiber (8.30 per cent), iodine (55.95 ppm), mucilage (4.02 per cent), soluble protein (1.33 per cent) showed highest results with I1M1F1 treatment combination.
