Abstract

Farmer field verification and participatory varietal evaluation trials were conducted at 1600 msal (Naudada), 1200 msal (Hemja) and 800 msal (Tutunga) of Kaski district in 2008/9 under plastic house condition. There were 4 varieties of tomato (Thims 1, Thims16, Srijana, and Bishesh) and 12 replications (one farmer as one replication) under Randomized Complete Block Design (RCBD). Altineem @3ml /lit of water; Alwin XL 2.5ml lit of water; Imidagold 1.5m/ lit of water and Lancergold 2g/lit of water were evaluated against whitefly. Similarly, ormicomin (25 g/plant), Furadan (carbofuran, 1g/plant), poultry manure (500 g /plant), mustard cake (50 g/plant),Neemajin (2 g/plant) were also evaluated for nematode. It was found that the tomato Cultivar Thims 1 produced higher yield (18.2 ton/Ropani at 1600 msal; 12.06 ton/Ropani at 1200 msal; 8.97 ton/Ropani at 800 msal) in all the altitudes respectively followed by Srijana, Thims 16 and Bishes. Similarly, fruit of Thims 1 was also recorded higher weight of per fruit i.e. 107. 21 g followed by Thims 16 (91.02 g), Bishes (69.38 g), and Srijana (55.5 g). The total number of fruit per plant was highest in the cultivar Srijana (167.0) followed by Thims 1 (126.29), Thims 16 (71.66) and Bishes (54.61). It was also found that the mustard cake treatment resulted lowest scoring of nematode followed by poultry manure and Ormicomin. Similarly, Imidagold was the most effective insecticide to control white fly.
