The main problem is that, not ploughing increases the need for pesticides, currently around 8% of energy used and reduces yield. While not ploughing increasing requiring 3x the pesticides might not be the case, a 20% reduction in yield seems plausible.
The main energy consumption in farming is fertilizer at around 50%, but more importantly half the emissions are related to animal agriculture. Cutting back on that would actually make a difference.
