“…However, the LCA research about rice variety selection is not well developed. Especially, in Iran, the literature has concentrated on the level of farm technology [49][50][51], the cultivation method [30,49], and the socioeconomic characteristics of farmers [52], to date. There are just very few studies about variety comparison: [53][54][55] carry out the assessment under experimental conditions, thereby failing to provide evidence about the real-world production context; and [56] focus on cover-crop-rice rotations, thereby failing to provide evidence on the baseline cultivation method in the area, i.e., rice monoculture [29].…”

This article aims to show the potential contribution of high-yielding rice varieties to achieve sustainable intensification in paddy farming, by focusing on a developing country. A comparative life cycle assessment of traditional vs. high-yielding varieties is carried out by comparing the area-based and yield-based results. Primary data are collected through a farm survey (49 farms in the Mazandaran province, Iran; spring 2018). The results highlight that high-yielding varieties can reduce the yield-scaled impacts. However, area-scaled impacts are subject to increase for most impact categories. Statistically significant trade-offs involve global warming potential (+13% per ha and −28% per t in high-yielding varieties) and fossil resource depletion (+15% per ha and −26% per t in high-yielding varieties). Pesticide management is the most alarming practice. High-yielding varieties increase pesticide consumption and related toxicity impacts both per t and per ha. This study is a new contribution to the literature by improving and broadening the mainstream productivity perspective of current life cycle assessment research about crop varieties. The lessons learnt from this study suggest that the trade-offs between yield-scaled and area-scaled impacts should be carefully considered by decision-makers and policymakers, especially in developing countries that, like Iran, are affected by the overexploitation of natural resources. Targeted policy and the development of farmer education and advisory services are needed to create the enabling conditions for farm management changes, including conscious use of production inputs while avoiding heuristics.

“…(Tabari, Fathi, Nouri-Ganbalani, Moumeni, & Razmjou, 2017). Mazandaran province located in the north of Iran is the largest rice-producing area of Iran, with 235,000 hectares of rice cultivation (Youseftabar, Heidari Sharifabad, & Majidi Heravan, 2020). The striped stem borer, Chilo suppressalis (Walker, 1863), is one of the main destructive pests of the rice crop in Iran (Tabari et al, 2017) and the world (Lei, Zhang, Yun, Zhou, & Peng, 2020).…”

Rice striped stem borer, Chilo suppressalis (Walker, 1863), is considered as a major destructive pest in paddy fields in the most regions of Iran. In this study, the impact of the rice cultivars, Tarom and Shiroudi, and the insecticides, cypermethrin, tebufenozide and the emulsion and granule formulations of diazinon were examined on the damage indices, percentages of dead heart and whitehead. The study was performed as factorial randomized complete block design using artificial infestation in semi-field conditions in Amol County. No significant interaction was found between rice cultivar and insecticide for all indices in both vegetative and reproductive stages (P>0.05). The results of main effects in both phenological stages indicated that the weight of live larvae and damage indices were significantly higher on Tarom than those of Shiroudi (P≤0.05), while no significant difference was detected in larval mortality on the cultivars (P>0.05). The main effects of insecticide were significant for all biological and damage indices (P≤0.05). The efficacies of tebufenozide and cypermethrin in terms of larval mortality were 47.57 and 74.90 % at vegetative stage reaching to 79.15 and 92.08% at reproductive stage, respectively. The 254 SEYYEDI-BADELY, S. M. et al.lowest efficacy in terms of larval mortality (73.33%) was obtained on plants treated by diazinon emulsion. At reproductive, the survived larvae weighed 170.80 mg.seedling -1 and the corrected whitehead index compared to the control reached 50.04% on plants treated by diazinon emulsion. According to the results, tebufenozide, regarding its relatively high efficacy and environmental compatibility, is suggested to be assessed further for integrated C. suppressalis management in the field conditions.
