Abstract:
The present investigation entitled “Study on the effect of organic manures and biofertilizers on growth, yield and quality of potato (Solanum tuberosum L.)” was conducted at Research area, College of Agriculture, Gwalior M.P. during Rabi 2020-2021 under agro-climatic and soil conditions of Northern Madhya Pradesh. Potato (Solanum tuberosum L.) is one of the most important vegetable crops widely grown in the world. It belongs to the family solanaceae and considered to be originated in South America. Potato is world’s fourth important food crop after wheat, rice and maize. The widely grown potato is an auto tetraploid with 2n=48.It is a heavy feeder of plant nutrients having very high requirement of nitrogen, phosphorus, potassium and other nutrients. The organic manures not only supply the nutrients but also improve the physical environment for better plant and tuber growth. The manures are low analysis nutrient carriers yet play a significant role in the fertilizer economy. Farm yard manure (FYM) is the most common organic manure used in India. Biofertilizers (Azotobacter +PSB) have been recognized as cheapest fertilizer input for developing countries like India as source of supplement on the application of chemical fertilizer for better crop production. The experiment was laid out in the Randomized Block Design with three replications. Each replication was comprised of 11 treatment combinations. The following treatment combinations involving RDF dose of fertilizers, vermicompost, Azotobactor and PSB were applied before planting in potato varietyKufri Chipsona-1.The result clearly shows that huge variation was noticed among the different treatment studied in this investigation for all the morphological parameters, yield parameters and quality parameters as well as economic parameters of potato. Results showed that the treatment T₈ (75% RDF + 25% Vermicompost + Azotobacter+ PSB) is the best application of organic manure and biofertilizers with different level of RDF doses and had significant effect on morphological, yield and quality parameters as well as economic parameters of potato. Treatment T₈ (75% RDF + 25% Vermicompost + Azotobacter+ PSB) gave maximum morphological parameters, yield parameters, quality parameters and economics parameters of potato as compared to all other treatments, however the minimum morphological, yield, quality and economics parameters were observed in treatment T₄ (50% RDF + 25% FYM + 25% Vermicompost).
