Accomplishments during 2013-14

    1. Design and Installation of Solar Energy Operated Greenhouse: A 200 square meter solar energy operated greenhouse equipped with fan-pad cooling system and low pressure drip Fertigation system was designed and installed at CPCT farm. Solar photovoltaic power plant of 2.6 Kwp was installed to energize the greenhouse of 200 square meter area. SPV system consists of solar module mounting structure, solar module, battery, solar PCU and wires. The greenhouse has two exhaust fans each of 500 watts and 1.0 hP pump and motor for cooling pad and Drip Irrigation. Capsicum and Cucumber grown in soil-less cultivation system inside solar energy operated greenhouse.



    1. Energy Budgeting in Solar Greenhouse : The total power required to energize the 200 sqm greenhouse was standardized as 2 Kw. Two exhaust fan each of 500 watt capacity, pump of 1 Kw to run the motor for sprinkling the water in the cellulose pads and low pressure drip fertigation system and 1.5 Kw heating rod were used in the greenhouse. The total energy consumption in the greenhouse varied from 300-800 Kw hr on monthly basis. The maximum energy consumption of 800 Kw hr was found in the month of June, mainly for cooling the greenhouse with fan-pad combination. The total annual energy cost was estimated as Rs 24,400/ to meet the energy requirement of 6100 Kw hr.



    1. Identification of new indeterminate tomato OPV linesIdentification of new indeterminate tomato OPV lines (SPT-1 and SPT-2) for polyhouse cultivation.

    1. Evaluation of Pusa Cherry Selction-1
      A promising cherry tomato line, Pusa Cherry Selection-1 was evaluated for performance under naturally ventilated greenhouse which gave a fresh fruit yield of 6.06 Kg/ plant.


    1. Evaluation of parthenocarpic cucumber with and without plastic mulch under different protected structures Evaluation of parthenocarpic cucumber
      Three parthenocarpic cucumber varieties viz; Kian, Isatis, and Hilton were evaluated for yield under naturally ventilated polyhouse (NVH), forced ventilated polyhouse (FVH) and insect proof net house (IPNH) with and without mulch. Isatis gave maximum yield (34.2 kg/m2) in FVP with mulch. However, the yield (32.40 kg/m2) was found with mulched condition under NVP with cost benefit ratio was 1:2.90 against 1:2.33 and 1:2.15 under FVP and IPNH respectively.



    1. Comparative studies of Capsicum with plastics mulch under different protected structures
      Two capsicum hybrids viz; Swarna and Indra were evaluated for yield under naturally ventilated polyhouse (NVH), forced ventilated polyhouse (FVH) and insect proof net house (IPNH) with and without mulch. Swarna gave maximum yield (14.2 kg/m2) in FVP with mulch. However, the yield (11.90 kg/m2) was found with mulched condition under NVP with cost benefit ratio was 1:2.60 against 1:2.15 and 1:1.46 under FVP and IPNH respectively.
      Capsicum with plastics mulch under different protected structures


    1. Comparative studies of Tomato (GS 600) with plastics mulch under different protected structures:
      A tomato hybrid GS 600 was evaluated for yield under naturally ventilated polyhouse (NVH), forced ventilated polyhouse (FVH) and insect proof net house (IPNH) with and without mulch. It gave maximum yield (24.5 kg/m2) in FVP with mulch. However, the yield (19.30 kg/m2) was recorded with mulch under NVP.



    1. Regulation of plant growth and flowering in short day planted chrysanthemum flowering in short day planted chrysanthemum
      A significant increase in plant height (from 22.5 cm to 84.7 cm) and flower size (7.4 cm to 18.3 cm) in plants of Thai Chen Queen was recorded due to application of GA3 at 150- 200 ppm.




    1. Evaluation of carnation varieties for cut flower production under naturally ventilated polyhouse
      Among four varieties of carnation, namely Guadina, Liberty, Ambrose and White Liberty evaluated for growth and  flowering characteristics under naturally ventilated greenhouse, variety Evaluation of carnation varieties for cut flower productionAmbrose produced quality cut flowers with stem length (81.5cm), stem diameter (0.72cm), flower diameter (5.20 cm), followed by Guadina and Liberty.


    1. Evaluation of IARI released chrysanthemum varieties for their suitability under naturally ventilated polyhouse.
      IARI released varieties namely; Pusa Chitraksha, Pusa Anmol, Pusa Aprajita, Pusa Centenary, Haldighati, Little Pink, Golden Ball, Thai Chen Queen and Addition were evaluated under naturally ventilated greenhouse for stem length and flower quality. Except Pusa Chitraksha and Thai Chen Queen, none of the varieties could produce acceptable stem and flower quality.


  1. Studies on crop water requirement of capsicum grown in coco-peat grow bags.
    The crop water requirements for Capcicum grown in coco- peat grow bags under low cost polytunnel green house varied from 300 ml to 800 ml per plant during December to April.
