Amrapali under high density orcharding. The maximum Plant height ( and cm), Plant spread ( and cm), number of panicles per plant (98.00 and ), was recorded with the application of T % RDF + 40 kg PSB /plant, closely followed by T 13 75%RDF + 20 kg PSB/plant and fruit set ( and 30.03%), fruit yield (22.72 and kg/tree), fruit yield ( and q/ha) and physic-chemical parameters viz., maximum fruit length (9.62 and 9.70 cm), width ( 6.22 and 6.39 cm), weight ( and g) was recorded with the application of T % RDF + 20 kg PSB /plant closely followed by T 14 75%RDF + 40 kg PSB/plant. However, the chemical composition of fruit viz., maximum TSS ( and Brix), reducing sugars (8.10 and 8.24%), non reducing sugar (9.65 and 9.94%), total sugar (17.75 and 18.18%) and minimum acidity content (0.124 and %) were recorded with the application of T % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB /plant closely followed by T 14 75%RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB/plant. Key word: Mango, Npk, Psb, Azotobacter and Vermicompost INTRODUCTION Mango (Mangifera indica L.) is a premier fruit crop of India considering its acreage, production and popularity among the people and therefore it is designated as the National Fruit of India. The fruit is excellent source of vitamin A, C and nutrients as well as carbohydrates 8. No other fruits are so intimately connected with the history and literature of India as mango. This premium fruit has been in cultivation in Indian sub continent for well over 4000 years.

2 Indiscriminate use of chemical fertilizers, biofertilizers on the sustainable production and pesticide and herbicides in horticultural crops fruit quality of Amrapali mango under high over four decades has adversely affected the density planting Ahmad et. al. 2,and Yadav soil fertility, biodiversity, ground water et.al. 10. Recommendation is also not available pollution and human health. Owing to these for the integrated nutrient management system limiting factors, conventional (chemical based) of crop production in Amarpali mango under farming has became non-sustainable. There are the climatic conditions of western UP which sufficient evidences that the intensive has been recognised as Agri. export zone of agriculture system has also caused decline in mango by the government of India. vitamin and mineral contents of fresh fruit. A It was therefore realised that the poor supply of nutrient seems to be one of the investigation on the balanced use of nutrients main causes for tree decline, low yield and through different sources in dwarf mango poor fruit quality. Since mangoes are mostly cultivar under high density planting would be consumed as fresh, they should be devoid of useful for sustainable production of quality fertilizer and pesticide residue. An mango. economically attractive and potential source of Keeping in view of above facts and the bearing plant nutrients in a balanced proportion is the potential of Amrapali mango in high density need of the day in maintaining the fertility and orcharding, the present investigation were productivity of agricultural soil. undertaken to find out the combined effect of The integrated nutrient management organic manures, inorganic manures and refers to a system which aims at improving biofertilizers on flowering, fruiting, yield and and maintaining the soil fertility for sustaining quality of mango fruits. increase in crop productivity and involves the use of inorganic fertilizers in conjunction with MATERIAL AND METHODS organic manures/wastes with inputs through The field investigations were laid out on 13 biological processes.

The organic sources of nutrients, i.e. FYM,(100 Kg/plant) and vermicompost two type dose 20Kg and 40 Kg/plant were applied around tree basin during first week of September. The biofertilizers, Azotobacter and 250 g per tree each were applied in first week of October at a depth of 30 cm around the tree trunk in respective treatment. The RDF of NPK (1000, 500, 1000g/tree) was applied to two type different dose (100%, 75%, RDF). The observations were recorded on flowering, fruiting, yield and quality was analysed as per AOAC (1). RESULTS AND DISCUSSION The application of organic sources of manure, biofertilizers and inorganic nutrient, improved the plant height, plant spread, number of panicles/plant, fruit set per panicle during both the years of experimentation (Table 1). The maximum plant height, plant spread, number of panicles/plant and fruit set per panicle was recorded with T 13 (75 % RDF + 20 kg PSB /plant followed by 75 % RDF + 40 kg PSB/plant (T 14 ). These values were minimum with T 1 (FYM + recommended NPK).The results were in accordance with the findings of Singh et al. (8) in bael. The flowering pattern was influenced due to treatments containing biofertilizers (Azotobacter and PSB) showed better results other than non-biofertilizer treatments. The role of Azotobacter in fixation of atmospheric nitrogen and PSB involved in solubilisation of phosphate in soil are responsible to compensate the reduced 1/4 th dose of NPK and maintaining better soil environment which ultimately reflect on the flowering of the tree. Positive response of Azotobacter and PSB were also reported in mango by Yadav et al. 10. Results are in close conformity with the findings of Singh et al. 8 in bael. The data presented in Table 2 revealed that the improvement in physical characters of fruits with respect to fruit size (fruit length and width), fruit weight in response to organic source of nutrients, Similar results have been reported by in Yadav et al.(9) in aonla and Yadav et al. 10 in mango. The maximum fruit size (length and width) was recorded with T 13 (75 % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB plant followed by 75 % RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB/plant). However, fruit weight showed similar pattern as for as the size of fruit. The fruit yield per tree influenced due to various treatments and recorded maximum with T 13 (75 % RDF + 20 kg PSB /plant followed by 75 % RDF + 40 kg PSB/plant). Similar findings were recorded by Ram and Rajput (5) and Yadav et al. (10). Increase in yield attributing characters with reduced NPK doses in association of biofertilizers 75 % RDF + 20 kg PSB /plant followed by 75 % RDF + 40 kg PSB/plant. Biofertilizers and organic fertilizers was due to the optimum supply of plant nutrients and growth hormones at desired amount during entire period of fruit growth, ultimately resulted in accumulation of more photosynthetic resulted into more length, diameter, fruit weight and yield of fruit. At same level of organic source of nutrient, biofertilizers was found more effective to improve yield and yield attributing The qualitative parameters of fruit were affected by different treatments and showed in Table 3. The results obtained from the study revealed the maximum total soluble solids with the application of T 13 (75 % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB /plant followed by 75 % RDF + 40 kg PSB/plant.) during both the years and it was minimum with T 1 while, reducing sugars, nonreducing sugar, total sugars, However, maximum reduction of acidity was noted with Copyright June, 2017; IJPAB 69

This results are in accordance with availability. On the basis of experimental the findings of Singh et al.(8) in aonla and findings, it can be concluded that the among Mahendra et al.
