ENHANCEMENT OF SHELF LIFE OF SIKKIM MANDARIN
            Problem diagonised: less shelf life of Sikkim Mandarin and lowest price in the market during harvesting.    Technology selected for assessment/refined: Use of honeywax as waxing material for enhancing the shelf life     Thematic area: Post Harvest management
CONTROL    Duration(days after harvest):0.    Avg.weight(gm):121    %damaged by mould:0     appearance:fresh    Duration(days after harvest):20.    Avg.weight(gm):113    %damaged by mould:10     appearance:start shriveled    Duration(days after harvest):30.    Avg.weight(gm):90    %damaged by mould:50     appearance:shriveled and shrink    Duration(days after harvest):40.    Avg.weight(gm):85    %damaged by mould:75     appearance:shriveled,Unmarketable    weightloss after 40 days=29.7%
WAXED FRUIT        Duration(days after harvest):0.    Avg.weight(gm):119     %damaged by mould:0    appearance:fresh    Duration(days after harvest):20.    Avg.weight(gm):110     %damaged by mould:5    appearance:fresh    Duration(days after harvest):30.    Avg.weight(gm):99     %damaged by mould:10    appearance:Look fresh    Duration(days after harvest):40.    Avg.weight(gm):95     %damaged by mould:10    appearance:Look fresh    Duration(days after harvest):50.    Avg.weight(gm):87     %damaged by mould:20    appearance:crack wax
weight loss after 40 days=20.8%    Recommendation:honeywax can be use for enhancing shelf life of Sikkim Mandarin    Constraint identified and feedback: Method of application for small and large scale may be introduce.
VARIETAL AND ADOPTIVE TRIAL ON PAHELI DAL
             Problem diagonised:Poor yield and loss of genetic purity    Technology selected for assessment/refinement:PD-3,PD-1, local(check)    Thematic area: Varietal and adoptive trial of local selection    Character studied:PD-3: Avg. no. of pod/plant=46,avg.on.of grains/pod=6,avg.fresh weight/24 plants=338gms,avg.dry weight/24plants=294gms,maturity period=107days.    PD-1:Avg.no.of plant/pod=46,avg.no.of grains/pod=5,avg.fresh weight/24plants=347gms,avg.dry weight/24plants=302gms,maturity period=107days.     Local(check):Avg.no.of plant/pod=50,avg.no.of grains/pod=6,avg.fresh weight/24plants=428gms,avg.dry weight/24plants=372gms,maturity period=114days.    RECOMMENDATION:Local is still performing better under better management practices however PD-1 can be a promising selection for better yield and duration of crop.    Constraints identified and feedback:: proper organic package of practice
VARIETAL EVALUATION ON LARGE CARDAMOM
             Problem diagonised:Adoptive cultivars viz.Ramsey,Sawney and Bhallangey in the district are susceptible to disease like Chirkey, Phoorkey and Blight.    Technology selected for assessment/refinement:ICRI Sikkim selection SK-1, SK-2, Sawney local Check.     Thematic area: Varietal and adoptive trial for disease resistance.    EVALUATION:SK-1:No.of pseudostem/plant=15,disease uprooted(%):8,    SK-2:No. of pseudostem/plant:14,disease uprooted(%):11.    Local Cv.Sawney:No. of pseudostem/plant:16 ,disease uprooted(%):20.
VARIETAL EVALUATION ON STRAWBERRY
            Problem diagonised:Strawberry not cultivated in the district    Technology selected for assessment/refinement:Cultivar Chandler, Cultivar Ofra    PLASTIC MULCH AND TUNNEL:Spacing:Chandler(45x45cm),Ofra(45x45cm)     No.of leaves/plant after 50days:Chandler(10),Ofra(12)    No.of crown:Chandler(2),Ofra(3)    Plant spread:Chandler(16cm),Ofra(19cm)    Berry weight:Chandler(9.4gm),Ofra(12.3gm)    Avg.yield/plant:Chandler(112gm),Ofra(105gm)    OPEN CONDITION:Spacing:Chandler(45x45cm) ,Ofra(45x45cm)    No.of leaves/plant after 50days:Chandler(8),Ofra(7)    No.of crown:Chandler(2),Ofra(2)    Plant spread:Chandler(12cm),Ofra(14cm)    Berry weight:Chandler(9.0gm),Ofra(8.6gm)    Avg.yield/plant:Chandler(70gm),Ofra(89gm)    Thematic area: Varietal evaluation     RECOMMENDATION:Strawberry can be grown successfully in the district under plastic tunnel and open condition.    Constraints identified and feedback:The production is under organic condition,some contingent measures for pest and disease infestation may workedout and package of practices may be develop.Birds-the major enemies.
