The present investigation entitled "Response of Integrated Nutrient Management on different physical characters of bael (Aegle marmelos Correa) cv. Narendra Bael-9" was carried out at Main Experiment Station, Horticulture, N. D. University of Agriculture and Technology, Kumarganj Faizabad (U.P.) 224 229 under sodic soil condition during the years 2014-15 and2015-16 to access the response of organic manure, inorganic fertilizer and Bio-fertilizers on different physical characters of bael fruit. There were nine treatments and were randomly replicated four times each treatments have different doses of organic manure, inorganic fertilizer and Bio-fertilizers like T1-100% NPK, T2-50 Kg FYM, T3-50 Kg FYM+ 100% NPK, T4-50 Kg FYM + 75% NPK, T5-50 Kg FYM + 50% NPK, T6-50 Kg FYM + 200g each (Azotobacter+ PSB),T7-50 Kg FYM + 100% NPK + 200g each (Azotobacter+ PSB), T8-50 Kg FYM + 75% NPK + 200g each (Azotobacter+ PSB) and T9-50 Kg FYM + 50% NPK + 200g each (Azotobacter+ PSB). The different parameters viz. fruit length (cm), fruit width (cm), fruit weight (kg/fruit), pulp weight (kg/fruit) and shell weight were noted after harvesting of fruits. These characters were statistically analyzed with the theory of Panse and Sukhatme. The treatment T7-50 Kg FYM + 100% NPK + 200g each (Azotobacter+ PSB) was found significantly superior for all the characters while the characters like specific gravity, number of seeds/fruit, number of cavities/fruit and shell thickness did not affected by the treatments and they found nonsignificant during both the years of experimentation (2014-2015 and 2015-2016).

The present investigation was carried out at the experimental farm of Doon (P.G.) College of Agriculture and Allied Science, Rampur, Selaqui, Dehradun during rabi season of 2018-19. The experiment comprised of eight treatments comprising basal and foliar application of nitrogen and potassium fertilizers along with a control treatment arranged in Randomized Block Design (RBD) with three replications. The observations were recorded for various growth and yield parameters. Results of the experiment indicated significant effect of different nitrogen and potash doses application on various parameters. The treatment T8 (50% RDK + Spray of K2SO4 @ 2% at 30 DAP) was found to be the best for improving growth characters, while treatment T4 (RDF160:100:120kg NPK/ha) was found best in terms of yield parameters. Based on the results of present investigation, it could be concluded that application of RDF 160: 100: 120 kg NPK/ ha can still be adopted by the farmers but with split applications of nitrogen and potassium as recommended dose for commercial cultivation of potato under present climatic conditions to achieve higher net returns per unit area provided all other agronomic package of practices are followed.
