Abstract

A two-year field experiment (2021-2023) was conducted to assess the yield and quality of Ashwagandha (Withania somnifera) under various environmental conditions. The C1cultivar (NMITLI-118) exhibited the highest yields of dry leaves (0.63 t ha^-1) and roots (1.08 t ha^-1) in the summer season (S2). Cultivar NMITLI-118 (C1) performs better in the summer season (S2, February sown), with average temperatures between 30-35 °C, where reduced moisture availability and heat stress stimulate higher synthesis of secondary metabolites and their constituents such as withanolides (0.36%), starch (24.24%), and starch-fibre ratio (0.80). Additionally, higher net returns of 2044.58 USD ha^-1 were obtained with NMITLI-118 during the summer season (S2). Furthermore, this approach allows farmers to utilise the lean period between the Rabi and Kharif seasons effectively treating ashwagandha as a bonus crop. The study also indicates that winter crops might be better for withaferin production, despite lower yields of roots and leaves.

环境条件对不同品种印度甘薯产量和品质的影响

通过为期2年（2021-2023）的田间试验，对不同环境条件下印度甜菊（Withania somnifera）产量和品质进行了评价。c1品种（NMITLI-118）夏季干叶（0.63 t ha-1）和根（1.08 t ha-1）产量最高（S2）。栽培品种NMITLI-118 （C1）在夏季（S2, 2月播种）表现较好，平均温度在30-35℃之间，水分有效度降低和热胁迫刺激了次生代谢物及其成分的合成，如金戊内酯（0.36%）、淀粉（24.24%）和淀粉纤维比（0.80）。此外，NMITLI-118在夏季获得了2044.58 USD ha-1的较高净收益（S2）。此外，这种方法使农民能够利用拉比和哈里夫季节之间的淡季，有效地将ashwagandha作为奖励作物。该研究还表明，尽管根和叶的产量较低，但冬季作物可能更适合生产冬氨酸。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
