His counterparts present at the expo in Mutithi village, Mwea constituency, urged farmers and Kenyans at large to plant trees.
"It's the rainy season, please let us plant trees," Forestry PS Gitonga Mugambi said.
"I urge each household member to plant at least 30 trees and help build a sustainable environment for agricultural farming now and in the future."
Cooperatives PS Patrick Kilemi said it is important for farmers to work together in groups and cooperatives.
"Agriculture has now established a good foundation that incorporates the youth," he said.
He praised the Agitech Expo and Yara Knowledge Centres for "offering learning opportunities and knowledge sharing to promote the uptake of agribusiness by the youth across the country".
Energy PS Alex Wachira called on farmers to plant trees and take care of the physical resources that provide water for farming and electricity generation.
"For us to reduce our power bills, we need to increase generation from the hydro and geothermal resources, which are dependent on trees and availability of water," he said.
"Let us, therefore, take up this tree initiative by the government as they are targeted to benefit us all now and in the future."
During the two-day expo, farmers were encouraged to embrace good agricultural practices (GAP) from land preparation all the way to post-harvest handling.
They were told this would increase crop productivity, quality and household incomes, in line with the government's agenda of providing food security for all.
