Abstract

The present investigation on "Impact of biostimulant on growth, yield, and quality of potato (Solanum tuberosum L.)" was carried out during the period of 2022–23 at "C" Block Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal. The farm is located very close to the Tropic of Cancer, having approximately 22.89°N latitude and 88.45°E longitude. The altitude of the place is about 9.75 m above sea level. The main objectives of this study were to find out the important impact of biostimulants and the ideal stage of application. In present days it shows that application of biostimultant has better opportunities for sustainable farming. The statistical analysis was done using Randomized Block Design (RBD) with three replications and seven treatments. It was noticed in the experiment that the application of biostimulants enhanced crop growth and promoted reproductive growth in later stages of the crop compared to control plants. Amongst the treatments, biostimulant application as foliar spray showed significant influences on growth, yield, and quality parameters. Seaweed extracts (Ascophyllum nodusum) applied topically had a substantial impact on the number of tubers produced per plant. Application of seaweed extracts (Ascophyllum nodusum) at 500 ml/acre during 25–30 DAPS and 40–45 DAP (T3) significantly registered the highest number of tubers per plant of 10.37. Significant responses were also observed on quality parameters with seaweed extracts, protein hydrolysates, and N-fixing growth promoters when applied as foliar sprays during different stages of plant growth. The highest value of 17.33 g/100 g of CHO was observed in the plants where seaweed extracts (Ascophyllum nodusum) were sprayed twice. Based on the results obtained from the present investigation, it may be concluded that application of seaweed extracts (Ascophyllum nodusum) twice days after planting, and again, 40–45 days after planting, may be suitable for potato cultivation for increasing production and improving the quality of potato tubers as compared to the control. T6 (protein hydrolysates and N-fixing growth promoter) also showed a good response in some parameters.

Conclusion

It can be inferred from the present findings that biostimulant application is essential to improving potato tuber yield. Although the application of stages is also one of the important factors for vegetative parameters of crop growth, based on the results obtained from the present investigation, it may be concluded that application of seed weed extract (Ascophyllum nodusum) at 500 ml/acre twice during 25–30 days after planting and again during 40–45 days after planting may be suitable for potato cultivation for increasing production and getting quality tubers of potato.
