Abstract: The experiment was carried out during the year 2009-2010 in Randomized Block Design (RBD) with five replications and eight treatments allocating mulching with different irrigation levels viz., 100%, 80% and 60% of water through drip and flood irrigation. The guava variety L-49 was taken with the objectives to study scheduling of irrigation under drip irrigation system, to workout the water requirement of guava and to assess the effect of black plastic mulch on growth and yield parameters of guava. The use of 80 per cent water through drip irrigation with plastic mulch was found effective for guava plants. The plants in respect of canopy spread, number of fruits per plant, fruit yield per plant and per hectare, days to 50 % flowering (minimum), days to fruit maturity (minimum) were found superior under 80 per cent water through drip with plastic mulch. While, highest plant girth and more number of primary branches were observed under 100 per cent of water through irrigation by flood system. The maximum number of leaves and twigs was observed with the treatment 60 % of water through drip irrigation.
