The National Geographic and Rolex Perpetual Planet Everest Expedition is a multidisciplinary project dedicated to understanding climate change and its impacts, improving climate predictions, and providing a framework for future research in mountain environments. This issue of One Earth offers a first look at the science emerging from the expedition. 2019 Everest Expedition scientific disciplines (with institutions involved in field sampling and/or analyses), sub-disciplines, and interdisciplinary interactions.

The experiment was conducted at the end of July in NHRC, Khumaltar (1332 masl) located at Longitude 27.6485o N and Latitude 85.3253o E situated at Province no. 3, Lalitpur, Nepal in 2077/04/18 to 2077/04/28. The experiment was carried out in Randomised Complete Block Design (RCBD) with four treatments and five replications. The genotypes Trishuli, Chaumase, Semi Light Long and Semi Long Green Bean were used as treatment. Phenotypic traits like Plant Height, Days to maturity, Number of node at harvest in main stem, Flower colour, No of pod per plant at harvest, Dry pod colour, Single pod weight at harvest, pod length, Seed yield per plant, Seed weight per pod, 1000 seed weight, Moisture %, Seed weight per plant(gm), seed weight per pod after drying per plant (gm), seed weight after drying were taken. Plant height was highest in Semi long ligh which is 332 cmt and lowest in Trishuli which is 294.48 cm. Total number of seed was found highest in Semi Long Green 8.6 and least in Trishuli 7. The highest yield was found in Trishuli 2.69 ton/ha followed by Chaumase 2.56 ton/ha, Semi long green 2.33 ton/ha, and the lowest was seen in Semi Long Light 1.51 ton/ha.
