Nanotechnology opens an enormous scope of novel application in the fields of biotechnology and agricultural industries, because nanoparticles (NPs) have unique physicochemical properties, i.e. high surface area, high reactivity, tunable pore size and particle morphology. Present study was carried out to determine the role of silver NPs (SNPs) to improve yield of L. SNPs (10-100 nm) were synthesised by green method using extract of Royle. Pea seeds were soaked and seedling were foliage sprayed by 0, 30, 60 and 90 ppm SNPs. The experiment was arranged as split-split plot randomised complete block design with three replicates. The application of SNPs enhanced significantly number of seeds pod, number of pods plant, hundred seed weight, biological yield and green pod yield over control. The highest yield was found when 60 ppm SNPs were applied. However, exposure to 90 ppm SNPs, the yield of the pea decreased significantly as compared with 30 and 60 ppm. This research shows that SNPs have definite ability to improve growth and yield of crops. Nevertheless, a comprehensive experimentation is needed to establish the most appropriate concentration, size and mode of application of SNPs for higher growth and maximum yield of pea.
纳米技术在生物技术和农业产业领域开启了广阔的新型应用前景，因为纳米颗粒（NPs）具有独特的物理化学性质，即高比表面积、高反应活性、可调节的孔径和颗粒形态。本研究旨在确定银纳米颗粒（SNPs）对提高豌豆产量的作用。采用绿色方法，利用翅果油树提取物合成了10 - 100纳米的SNPs。将豌豆种子浸泡，并对幼苗进行叶面喷施0、30、60和90 ppm的SNPs。试验采用裂区裂区随机完全区组设计，重复三次。与对照相比，施用SNPs显著提高了每荚种子数、单株荚数、百粒重、生物产量和青荚产量。施用60 ppm SNPs时产量最高。然而，与30 ppm和60 ppm相比，暴露于90 ppm SNPs时，豌豆产量显著下降。本研究表明，SNPs具有提高作物生长和产量的一定能力。然而，需要进行全面的实验，以确定SNPs最适宜的浓度、尺寸和施用方式，从而实现豌豆更高的生长量和最大产量。
