A field experiment was carried out to study the effect of types of irrigation and organic mulches on growth of mulberry at Department of Sericulture, University of Agricultural Sciences, Bangalore during Kharif 2021. The experiment was laid out in Factorial Randomized Complete Block Design (FRCBD) with fourteen treatment combinations and three replications. Main plots include two different types of irrigation viz., Surface drip irrigation- I1 and Subsurface drip irrigation- I1 at 15-20 cm depth both at 0.75 Cumulative Pan Evaporation (CPE) and Organic mulches (M1 -Mulching with glyricidia leaves, M2 - Mulching with pongamia leaves, M3 - Mulching with neem leaves, M4 -Live mulch with cowpea, M5 - Live mulch with horsegram and M6 - Live mulch with dhaincha and M7 -control without mulch, observations were recorded at 30, 45 and 60 Days After Pruning (DAP). The results of the experiment revealed that the subsurface drip irrigation at 0.75 CPE recorded highest shoot length (79.14, 111.38 and 143.33cm, respectively), number of shoots plant-1 (15.32, 19.69 and 27.43 no. respectively), number of leaves plant-1 (141.72, 252.02 and 350.96 no. respectively) and leaf area (115.45, 165.31 and 115.45 cm² respectively). Among mulches live mulch with cowpea showed highest shoot height (90.53, 118.78 and 149.82 cm respectively), number of shoots plant-1 (16.10, 21.20 and 25.30 no. respectively), number of leaves plant-1 (146.05, 259.81 and 360.96 no. respectively) and leaf area about 119.25, 170.09 and 246.54 cm2 respectively. However, effect of irrigation methods and different mulches differed non-significantly. [ABSTRACT FROM AUTHOR] |
