“…For their part, Sikora et al ( 2020 ) recommend the use of slow-release fertilizers as a way to reduce agricultural emissions. Yang et al ( 2022 ) show that higher farmer education with low nitrogen input contribute to eco-efficiency. Along the same lines, Shahbaz et al ( 2022 ) reveal that farmers in a province of Pakistan are changing their use of fertilizers in order to counteract the effects of CC, and also demonstrate the importance of ensuring the efficiency of innovation.…”

The EU supports agricultural policies to help farmers meet the challenges of climate change (CC) by promoting more sustainable and environmentally friendly practices. This study focuses on the European primary sector (agriculture, forestry, and fisheries), productive activities that meet humanity’s basic needs, although this sector does not account for a dominant share of GDP. The analysis uses a panel data sample of 22 European countries for the period 2012–2019, and seeks to answer the following research questions: Is there a direct relationship between agricultural innovation efficiency and the technological advances implemented? What effect do GHG emissions and innovation efficiency have on CC? Which agricultural practices have the greatest effect on the volume of GHG emissions? The results indicate that the European primary sector has registered an average rise in productivity of 4%, mainly driven by technological improvements. This underscores the need for agricultural innovation policies that focus not only on improving aspects related to technology but also on making better use of existing resources. In addition, the econometric models estimated confirm that efficiency levels are the most influential determinants of temperature change, while GHG emissions are primarily explained by their own historical values. Ultimately, research and development is a tool that can be used to curb CC, along with the proper use of land and fertilizers. There is thus a need to foster novel agricultural practices that help reduce emissions while ensuring the efficiency of the sector.

“…Sugarcane is mostly cultivated under rainfed condition, often in low fertile N-limited soils. It is highly responsive to N supply and, consequently, overuse of inorganic N fertiliser to boost cane yield is widespread (Robinson et al, 2011;Yang et al, 2022). For instance, N application rate for sugarcane ranges from 400 kg ha −1 in certain production regions in India to 1381 kg ha −1 in some areas of China, the two major sugarcane producing countries (Robinson et al, 2011;Yang et al, 2022).…”

As with most other crops, NUE of sugarcane is relatively low, with crop recovering 20-40% of N applied even in wellmanaged production systems following best crop management practices (Luo et al, 2022).…”

Excessive use of nitrogen (N) fertilizer for sugarcane cultivation is a significant cause of greenhouse gas emission. N use-efficiency (NUE) of sugarcane is relatively low, and considerable effort is now directed to exploit biological nitrogen fixation (BNF) in sugarcane. We hypothesize that genetic base-broadening of sugarcane using high-BNF Saccharum spontaneum, a wild progenitor of sugarcane, will help develop N-efficient varieties. We found remarkable genetic variation for BNF and growth in S. spontaneum accessions, and BNF in some accessions remained highly resilient to inorganic N application. Physiological and molecular analyses of two S. spontaneum accessions with high-BNF capacity and growth, namely G152 and G3, grown under N replete and low N conditions showed considerable similarity for total N, NH4-N, soluble sugar, indoleacetic acid, gibberellic acid, zeatin and abscisic acid content; yet, they were strikingly different at molecular level. Global gene expression analysis of G152 and G3 grown under contrasting N supply showed genotype effect explaining much of the gene expression variation observed. Differential gene expression analysis found an over-representation of carbohydrate and amino acid metabolism and transmembrane transport genes in G152 and an enrichment of lipid metabolism and single-organism processes genes in G3, suggesting that distinctly divergent metabolic strategies are driving N-related processes in these accessions. This was attested by the remarkable variation in carbon, N, amino acid and hormone metabolism-related gene expression in G152 and G3 under high- and low-N supply. We conclude that both accessions may be achieving similar BNF and growth phenotypes through overlapping but distinctly different biochemical and molecular mechanisms.

“…Sugarcane belongs to a highly suitable substrate to produce bio-products for foods, feeds, fiber, as well as renewable bioenergy. It requires policy to overcome the conflicts of interests of its functionalities, on which life cycle assessment consideration, including greenhouse gas emission, environmental problems, and human health [7,8,9], especially when organic soil, wetland, or peat soil for the cultivation development [10] would be taken in the development program. It is also to consider the subsidence potency regarding the sustainability of the cultivation systems [11].…”

Probably effective application of fly ash granules for ameliorants on sugarcane has not been meaningful reported in tropical agricultural systems and no exact results have not been established. The experiment was arranged from January 2014 up to May 2015 at IPB Bogor, Indonesia. This study aimed to determine the improvement level of additional fly ash granules as soil ameliorants on peat soil in sugar cane cultivation compared to the application of dolomite. The experiment used a complete randomized block design in sub-optimal peat soil. There were five levels of treatment at 50 kg peat soil weight at polybag as the following: without the addition of ameliorant as control (C0) at pH=4.0; Mixing with fly ash granule at pH 6.0 (C1); Mixing with fly ash granule at pH 7.0 (C2); Mixing with dolomite at pH 7.0 (D1), Mixing with dolomite at pH 6.0 (D2). The fly ash granule and dolomite application at a starting value of pH 6.0 or pH 7.0 exposed reliable impact to maintain the pH value of peat soil at least for one year during the growth of the sugarcane plant biomass until harvest. The application of fly ash granule at the starting value of pH 6.0 showed a better effect on plant growth biomass and was sufficient to ameliorate the peat soil to achieve the optimum sugar yield. More than this application rate would be luxurious, it causes no increase in sugar production.
