| Summary: | Field experiment was conducted for two years at Central Potato Research Institute Campus, Modipuram to study
the effect of organic+homeopathic and inorganic treatments on potato. Potato (Solanum tuberosum L.) harvested
after curing were stored at elevated temperature (12±0.5oC) with CIPC, (Isopropyl-N-(3-chlorophenyl carbamate) as
per modern technology adopted by farmers. The experiment was laid out in sub-plots with three sources of nutrition
(organic+homeopathic nutrition) and inorganic treatments and three cultivars Kufri Bahar, Kufri Sindhuri and Kufri
Chipsona-3 in main plots. Results showed that dry matter responded positively to inorganic treatment over organic.
Variety Kufri Chipsona 3 recorded maximum dry matter followed by Kufri Sindhuri, while lowest dry matter was
reported in Kufri Bahar. Organic and homeopathic nutrition resulted in significantly superior chip colour as compared
to inorganic treatment. During both the years, potato chips prepared from cv. Kufri Chipsona 3 tubers with organically
treated one had better chip colour. Organic and homeopathic nutrition significantly reduced mean reducing sugars in
stored potatoes as compared to inorganic treatment. During both the years of experiment, reducing sugars were low
in organically fertilized potatoes in comparison to inorganically fertilized crop. Mean sucrose content in potatoes
stored at this temperature was at par in first year, while significantly lower values were observed in second year of
experiment in organic+homeopathic treatment. Phenols content were significantly lower in organic and homeopathic
treatment over inorganic nutrition across the genotypes in both the years during storage. |
