ADAPTIVE RESEARCH ON RICE/POTATO ROTATION MODEL (SRI FOR RICE AND MINIMUM TILLAGE METHOD FOR POTATO) IN PADDY LAND OF PHU BINH DISTRICT, THAI NGUYEN PROVINCE

Abstract

The rice/potato rotational model (SRI-GMP model) was built and conducted in Phu Binh district, Thai Nguyen province, Vietnam during 2018 to 2019. The study was set up and compared conventional rice farming (rice monoculture does not apply SRI – control); monoculture of rice with SRI application; and SRI-GMP practice. Applying SRI-GPM created an ecological balance, reducing greenhouse gas emissions, helping people raise awareness about environmental protection and responding to climate change. The yield of potatoes reaching 25 tons/ha made an increase in income from 4.9 million VND/ha, 210.5 thousand VND/labor-day and 1.09 VND/VND for the investment capital in conventional cultivation of monoculture of rice into 141.3 million VND/ha, 644.4 thousand VND/ labor-day and 2.75 VND/VND for the investment capital in SRI-GPM cultivation, respectively. SRI-GPM created a cooperative connection between farmers, companies, scientists and government, providing opportunities for farmers to participate in the value chain to increase high added value and stable for local people.
