The production of natural rubber in Malaysia is primarily dominated by smallholders representing almost 95% of the total rubber plantation, while commercial estates constitute the remainder. The natural rubber industry is an integral part of the Malaysian economy, with 2.6% of with the total contribution of exports valued at more than RM20 billion annually. Therefore, the three key inputs that affect the productivity of smallholders in all states throughout Malaysia should be critically explored There is limited literature on the production of rubber by smallholders. The labour consumption, land area and adherence to agronomic practices are the main inputs and variables in this study. The Ordinary Least Square (OLS) was used to analyse the correlation of each input with rubber production by referring to the concept of the production function. The results discovered that 96% of rubber production yields are explained by independent variables consisting of labour, plantation area, weeding and cultivating activities. Furthermore, the total plantation area and adherence to agronomic practices positively affect total rubber production, while inefficient use of labor negatively affects total rubber production

Industrial plantations have had some of the most significant impacts on the surface of the earth, and while natural rubber is no longer hegemonic, palm oil, soybeans, maize, and coffee production, each with its own nexus of human and nonhuman agents, continue to have major impacts on the environment and human health. The conclusion briefly analyzes post-1975 memories of colonial and national plantations as participants use the memory of rubber production to negotiate their relationship to each other and to the politics of Vietnamese history in the present. Planters’ associations in France recall heroic times, the Communist Party celebrates the heroic contributions of rubber workers to the socialist revolution, and some workers use memories of colonial efficiency to critique present socialist mismanagement. Many Laotian and Cambodian farmers, and their allies, decry Vietnamese “colonialism” that is associated with the expansion of Vietnamese rubber company interests into the territory of neighboring nations, thus calling into question the continuing role of tropical commodities in shaping Southeast Asian lives.
