:The results of present investigation indicated that, among the different shading intensities 50 per cent shading intensity recorded the minimum number days required for germination (8.00) and emergence of third leaf (13.50) as compared with remaining shading intensities. The highest number of leaves, plant height, number of branches, internodal length of leaves were observed in 50 per cent shading intensities (21.92, 19.17cm, 6.17 and 6.08 cm, respectively). The highest leaf area was observed in 50 per cent shading intensities (4.67 cm 2 ) while among the varieties, the variety, JD-1 recorded the highest leaf area (4.40 cm 2 ). The minimum days required for harvesting of coriander was recorded in 50 per cent shading intensities (36.67 days) as compared to open conditions (42.17 days). The highest yield per plot (3.40 kg) and per hectare ( 50.23 q) of coriander was recorded in 50 per cent shading intensity as compared to other shading intensities while highest yield per plot and per hectare was recorded variety of JD-1 (2.53 kg per plot) and (37.44 q per ha.), respectively. The interaction effect between shading intensities and variety, all the growth and yield parameters of coriander cultivars were found to be non-significant.

Cherry tomato (Solanum lycopersicon var cerasiforme) is small size fruits, with a bright red colour resembling to cherry and becoming popular in the retail chains which are marketed at a premium price. The field experiment was conducted to study the effect of different (35, 50 and 75 per cent) shading intensities on growth and yield (qha , respectively). Among the different shading intensities and genotypes, maximum plant height was observed in 75 per cent shading intensity and genotype KSP -113 at 30 days interval (74.70 and 60.95 cm, respectively). The minimum days to 50% flowering of cherry tomato were observed in cherry tomatoes grown under 35 per cent shading intensity (45.00 days) as compared to other shading intensities while minimum days to 50% flowering were observed in genotype KSP-113 (44.00 days). The maximum length of the cluster (9.58 cm), the weight of cluster (27.67 g), number of fruits per cluster (9.42) and number of pickings (11.67) were observed in 35 per cent shading intensities and in genotype KSP-113. The cultivation of KSP-113 genotype under 35 per cent shading intensity was found to be most sustainable for improving growth and yield of cherry tomato during the summer season.
