Eco-friendly plasma technology is appeared as promising for the improvement of crop yield and hence it was applied to study the paddy plant growth and yield. Applications of plasma technology in this study are two-fold: (1) paddy seeds (Oryza sativa L.) were treated with low pressure (100 torr) glow air discharge (LPGAD) plasma for duration of 30, 60, 90, 120 and 150 s for finding the highest germination rate for field application, and (2) plasma activated waters (PAWs) were prepared and applied as foliar spray to the plants grown from the treated seeds to investigate the combined effects on plant growth, yield and total soluble protein and sugar concentrations in the produced paddy grains. Seedlings grown from the 90 s LPGAD plasma treated seeds, depending on the results obtained from seed germination test, were transplanted in the field and PAWs were applied 1–5 times during vegetative growth stage of the paddy plants. The results reveal that (a) the maximum paddy seed germination rate of ~ 7% with respect to control was obtained from 90 s treatment duration, out of five treatment durations, with LPGAD plasma, (b) plants growth parameters were enhanced due to the combined effects of plasma seed treatment along with PAW application, (c) defense mechanisms of plants were improved through enhancement of enzymatic activities, (d) concentrations of total soluble protein and sugar were enhanced in the paddy grains, and (e) finally yield was increased by ~ 16.67%.

环保的等离子技术似乎有望改善作物的产量，因此被用于研究水稻的生长和产量。等离子技术在这项研究中的应用有两个方面：（1）水稻种子（Oryza sativa L.）经过低压（100 torr）辉光空气放电（LPGAD）等离子体处理，持续30、60、90、120和150 s的持续时间，以求出最高的发芽率以用于田间应用;以及（2）等离子体活化水（PAW）制备了叶面喷雾剂，并将其作为叶面喷雾剂施用于处理过的种子所生长的植物上，以研究其对植物生长，产量以及所产生的稻谷中总可溶性蛋白质和糖浓度的综合影响。从90年代经LPGAD等离子处理过的种子中生长的幼苗，根据种子发芽试验的结果，被移植到田间，在水稻植物的营养生长阶段施用PAW 1-5次。结果表明：（a）从90 s的处理时间（五个处理时间）中获得的相对于对照而言，最大的水稻种子发芽率约为7％。
