Varietal and micronutrient trials on spring and rainy season tomato conducted at outreach research sites, 1995/96.

A pre-production verification trial on summer season (off-season) tomatoes was planted at 4 Outreach Research (OR) sites (650-1100 m asl) to compare and verify the performance of tomato cultivars CH-154 and Pusa Ruby with or without the application of trace elements. Irrespective of the application of trace elements, CH-154 was 4, 2 and 7 days earlier than Pusa Ruby at Dhanubase, Khabara and Kudule, respectively, to produce marketable fruits. Varietal effect on marketable fruit yield was significant at 2 sites where, irrespective of trace element application, CH-154 outyielded Pusa Ruby by 32% at Khabara but Pusa Ruby outyielded CH-154 by 77% at Hemja. The effect of trace elements on marketable fruit yield was significant only at Khabara where irrespective of cultivar, trace elements increased marketable fruit yield by 23%. A farmers' field trial on rainy season tomatoes was planted at 4 OR sites (650-1100 m asl) to identify the appropriate cultivar(s) of tomato for rainy season cultivation in l

ow-to-mid-hill areas. The overall treatment mean indicated that PT-4225 and BL-410 were the earliest cultivars (57 days) which produced marketable fruits 4 days earlier than the latest cultivar BL-350 (61 days). Varietal effect on marketable fruit yield was significant at all 4 sites. The overall treatment mean across the locations indicated that BL-355 produced the highest fruit yields: 24%, 25%, 42% and 77% more marketable fruits than BL-410, PT-4225, BL-350 and CL-1131, respectively. However, BL-355 was not liked by farmers and traders. BL-410 was found the most suitable cultivar in terms of good yield, attractive fruit shape and size and comparative freedom from insect pest and disease damage. Similarly, PT-4225 was also found appropriate on the basis of fruit yield and postharvest shelf life.
