Kampong Thom, May 11, 2025 – The Cashew Nut Association of Cambodia (CAC) and Rohat Agrotech Co., Ltd hosted a workshop on climate-smart farming techniques at its head office, bringing together 123 farmers and delegates from 12 provinces. The event focused on sustainable practices to enhance cashew yield while adapting to climate challenges.

A key highlight was the discussion on” The role of leaf in plant growth and optimizing production,” focusing on timely pruning and balanced nutrient application to improve soil health as well as the cashew trees to be more adaptable to extreme weather. Furthermore, the cost reduction approach by adopting molasses-based HEM (Home-made Effective micro-organisms) Liquid fertilizer and compost was discussed.  Farmers were encouraged to adopt this sustainable alternative to boost resilience.

Leaves are the source of glucose derived from chlorophyll through the photosynthesis process. Glucose is the source of energy for bud break, new shoots or branches, flowers, fruit, and root development. Leaf damage normally leads to yield reduction. Thus, information on proper leaf management will be useful for the farmers to make decisions.

The workshop also addressed concerns over Thiourea; a chemical used to accelerate bud break in cashews. CAC experts cautioned against its use, citing potential long-term harm to trees and soil, and instead promoted natural alternatives.

Last but not least, the workshop also discussed the proper methods to tank-mix pesticides of different formulations and foliar fertilizers in order to help farmers avoid the wrong mixing procedure, which may result in phytotoxicity and waste money or degrade the efficiency of the pesticides and foliar fertilizer.

CAC reaffirmed its commitment to supporting farmers with climate-resilient, sustainable methods to secure Cambodia’s cashew industry.
