Abstract:
The potato (Solanum tuberosum L.) is the most important non-cereal world food crop and it is next only to rice, wheat and corn as a major crop in terms of total food production.It requires large dose of chemicals in terms of fertilizers and pesticides. Due to environment and health concerns, it is important to produce organic potatos. The present study deals with the development of carrier based formulations of beneficial microbes like Azotobacter chrococcum, Pseudomonas fluorescens, Bacillus megaterium and evaluating them in potato production. The three carriers namely Charcoal, Karanja cake and Telcom powder were used for preparation of formulations. The effect of these formulations were studied on growth, yield and biochemical parameters of selected vegetable crop. Total eight treatments were applied including control, three treatments involving application of formulations, three treatments with 50% chemical required in combination with formulations and one treatment with 100% chemical(N,P,K) required for potato. The significant increase in % germination (81.73 %) and % survival (90.47%) and growth parameters of potato crop like plant height (42.4. ±1.37 cm), no of leaves (46.5±1.29), fresh weight (891.5±6.75) and dry weight (98.73±3.5) were observed in combined application of Karanja cake based formulation+50 % chemical (N,P,K). The plant nutrient content N (41.7±2.86mg/g), P (11.55±.23mg/g), K (33.31±.56mg/g) chlorophyll Ch a (2.967±.014 mg/g), Ch b (.234±.004 mg/g) and total chlorophyll (3.469±.026mg/g) were also found maximum in Karanja cake based formulations+50% chemical required. The total sugars 9.42±.19 mg/g ,fibre content24.62±1.1 mg/Kgstarch12.11±.90g/Kg were found.
