ジャンムー地域の亜熱帯条件で2020〜2025年にわたり、4品種のコムギを対象に統合養分管理（INM）・有機農業・自然農法の長期影響を比較した。HD-3237×INMが最高の収量・炭素持続性指数・純収益と最低のカーボンフットプリントを示し、有機農業では土壌有機炭素と炭素隔離が、自然農法ではエネルギー生産性と利用効率が最大となった。農業システム選択が炭素収支とエネルギー効率のトレードオフを生むことを実証している。
English
A five-year field trial in subtropical Jammu compared integrated nutrient management (INM), organic, and natural farming across four wheat varieties, assessing carbon footprint, energy indices, and productivity. HD-3237 under INM gave the highest yield, carbon sustainability index, and benefit-cost ratio with the lowest carbon footprint, while organic farming maximized soil organic carbon and carbon sequestration, and natural farming maximized energy productivity and efficiency. The study quantifies trade-offs between carbon, energy, and yield outcomes in sustainable farming systems.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、農業分野のScope 3排出や食品バリューチェーンの脱炭素に関心を持つ企業・自治体にとって、土壌炭素隔離や投入エネルギー効率の定量化手法は参考になる。ただし日本固有の政策・制度との直接接続は薄い。
In the global GX context
This contributes to the growing body of empirical evidence on agricultural carbon accounting and energy efficiency, relevant to Scope 3 land-use emissions and food-system decarbonization under frameworks like SBTi FLAG and CSRD. It offers a replicable field-level methodology for comparing farming systems' carbon and energy performance.
👥 読者別の含意
🔬研究者:農業システム間の炭素・エネルギー・収量のトレードオフを長期圃場データで示した実証研究として参考になる。
🏢実務担当者:食品・農業関連企業がScope 3やFLAG目標を検討する際、作付体系別の炭素・エネルギー指標の比較手法を参考にできる。
🏛政策担当者:農業脱炭素政策や環境直接支払いの設計において、INM・有機・自然農法の効果差を示すエビデンスとして活用可能。
📄 Abstract（原文）
With increasing emphasis on sustainable agricultural practices, understanding their long-term impacts on crop productivity, resource-use efficiency and environmental sustainability has become essential. The experiment was conducted at Krishi Vigyan Kendra, Jammu during the rabi seasons from 2020–21 to 2024–25 to evaluate the long-term effects of sustainable farming systems on carbon budgeting, energy indices and productivity of different wheat varieties under the subtropical conditions of Jammu region. The study was laid out in a factorial randomised block design with 3 replications comprising 12 treatment combinations. Two factors were evaluated: the first factor consisted of four wheat varieties (JAUW-584, JAUW-672, DBW-222 and HD-3237) whereas the second factor included integrated nutrient management (INM), organic farming and natural farming. The results revealed that the wheat variety HD-3237 under INM recorded higher dry matter accumulation, grain yield, yield sustainability index, production efficiency, nutrient uptake, carbon sustainability index, net returns and benefit-cost ratio along with the lowest carbon footprint. In contrast, HD-3237 under organic farming exhibited higher soil organic matter, greater carbon sequestration and the lowest bulk density. Among the energy indices, HD-3237 under natural farming recorded the highest energy productivity and energy-use efficiency along with the lowest input energy requirement. Overall, the wheat variety HD-3237 under INM recorded the highest grain yield, nutrient uptake, carbon sustainability index and benefit-cost ratio. However, HD-3237 under organic farming resulted in higher soil organic carbon and carbon sequestration whereas the same variety under natural farming recorded the highest energy productivity and energy-use efficiency.
