Abstract

Year round production systems of high yielding vegetables inside the naturally ventilated polyhouse was evaluated at Horticulture Research Station, Malepatan, Kaski in fiscal year of 2020/21 and 2021/22. Year round production of high value vegetables is not profitable in open field thus development of technologies for protected structure is envisaged. The standard cultivation practices inside poly houses were followed for the crop cultivation period of major vegetables. The crops were grown in the defined area (m2 ). Total yield and the marketable price per kilogram were recorded for evaluation. During 2020/21, the high yielding commodities were capsicum (18-20 t/ha) planted in second week of May, tomato (50-60 t/ha) planted in second week of June, pole bean (50-55 t/ha) planted in first week of August, cucumber (80 t/ha) planted in the last week of December. Similarly during 2021/22, capsicum (20 t/ha) planted in first week of May, tomato (50-60 t/ha) planted in third week of June, pole bean (50-55 t/ha) planted in first week of August, Broad leaf mustard (BLM) (40-50 t/ha) planted in first week of August, cucumber(80-100 t/ha) planted in last week of December and tomato (60-65 t/ha) planted in last week of February were high yielders. From the two year's result, cropping sequence of Capsicum/Tomato-Asparagus bean/French bean-Cucumber or Leafy vegetables (BLM)/Coriander-Tomato-French bean/Asparagus bean sequence were identified for proper utilization as well as to increase the income from protected structure in the mid hill region of similar climates.
