“…With regard to the labour force, Alam, Kobayashi, Matsumura, Eshan, Faridullah, and Siddighi (2012) and Sithole, Lagat, and Masuku (2014) pointed out that the head farmer would have more time to engage in O&M when family members are there to contribute their labour. The availability of more household labourers was good when adopting adequate technologies for intensive farming (Bhatta, Matsuoka, Sapkota, & Shrestha 2010). Muchara, Ortmann, Wale, and Mudhara (2014), Nhundu, Mushunje, Zhou, and Aghdasi (2015) and Wang, Chen, and Tao (2014) reported a positive and significant effect on farmers' participation when the number of working adults in the household is high.…”
