Areas of Interest: 

1. Genetic improvement of Luffah i.e. sponge gourd (Luffa cylindrica (Roem) L.), ridge gourd (Luffa acutangula (L.Roxb.) and satputia (Luffa hermaphodita).

2. Coordinating and monitoring of  breeder seed production programme and other related works of Project Coordinating Cell under AICRP on Vegetable Crops and involved in seed production of vegetables seeds at the Institute level.

Major Research Accomplishments: 
  • Developed 14 vegetable varieties/hybrids (04 in Sponge Gourd, 03 in Bottle Gourd, 02 in Tomato, 01 each in Ridge gourd, Pointed Gourd, Bitter Gourd, long melon & Pumpkin.  Out of these, 05 varieties/hybrids were identified and released for cultivation in different agro climatic condition at National level and 9 at U.P. State level.
  • First record of melon weevil (Coleoptera: Curculionidae) from ridge and sponge gourd in the world from India and its bionomics, diurnal activity and ecofriendly management: The melon weevil is a serious emerging pest of Luffa crops. About 70–80 percent fruits and 30 percent shoots are damaged by this weevil. 
  • Coordinating and monitoring of breeder seed production at national level under AICRP on Vegetable Crops and involved in seed production of vegetables seeds at the Institute level.
  • Looking after the work of  DUS Testing of vegetable crops, a Central Sector Scheme of PPV&FRA, New Delhi for protection of IPR issues of candidate varieties.

B. TECHNOLOGIES DEVELOPED (4)

1. Pre-emergence application of pendamethalin @ 0.75 kg ai/ha followed by  one hand weeding  at 40DAS is the best treatment for weed control in pea cv. Kashi Udai as it gives the highest B:C ratio and highest seed yield at IIVR, Varanasi of agroclimatic zone-IV (Vegetable Science 43 (1):1-12:142-144).

2. Seed treatment with carbendazim @ 2g/kg seed + imidacloprid @ 2ml/kg seed + micronutrient mixture @ 20g/kg seed resulted in maximum germination and vigour indicec in chilli cv. Kashi Komal at IIVR, Varanasi (Proceeding of XXXIV Annual Group Meeting of AICRP-VC), page no. 28). 

3. Seed priming with K2HPO4 (0.01M) or GA3 (100ppm) for 24h improved germination (71%) and vigour of less viable brinjal cv. Kashi Taru seed at ICAR-IIVR, Varanasi (Proceeding of XXXV Annual Group Meeting of AICRP-VC), page no. 91). 

4. Sowing of Palak cv. All green during October with one cutting gave a significantly higher yield (15.66q/ha) along with highest seed quality at Varanasi.The BC ratio was also higher. Hence, it is recommended for agro-climatic condition of zone-IV (Proceeding of XXXVI Annual Group Meeting of AICRP-VC), page no. 100).
