A study was conducted during 2004-08 on the impact of black polyethylene film (100 Jl thick) on root growth, flowering and fruiting characteristics and nutritional and hydrothermal properties of soil, anatomical changes in roots and pedicel and ;stomatal behaviour of leaves in 'Chausa' and 'Langra' mango (Mangifetra indica L.). Mulching treatment stimulated the lateral root growth in nutrient rich upper soil layer in particular. The anatomical structure of roots of mulched trees showed more unicellular and tubular root hairs with prominent conductive tissue compared to nonnmulched ones. Primitive abscission zone in the pedicels with increase in size of stomatal pore in leaves of mulched tree was categorically noticed. Enhancement in flowering (35 to 50%), maximum fruit retention (381.61 and 566.47) and minimum fruit drop (14 and 51) with enhancement in yield (82.60 and 117.50 kg/tree) in both the cultivars was recorded in mulched trees compared with the non-mulched ones. Alleviated soil temperature (21.0-25.8) was also noticed in the mulching treatments. The data on nutritional status clearly revealed the improvement in the level of N (2.50%), P (18.69 ppm), K (130.0 ppm), Ca (521.95 ppm), Zn (0.93 ppm), Cu (1.61 ppm), Fe (4.90 ppm), in soil and leaves in both the cultivars with different magnitude with mulching. However there was no significant changes in Mn level, pH of soil, organic content in mulched as compared to non-mulched soil. Significant increase with cultivars variation in gas exchange parameters and chlorophyll fluorescence was recorded in mulched trees.
