Abstract

The present investigation was conducted at Jawaharlal Nehru Krishi Vishwavidyalaya, KVK, Chhindwara (M.P.), India, during 2019-2020 and 2020-2021 to investigate the impact of NAA and RDF levels on plant growth and fruit quality of pomegranate (Punica granatum L.) in central India condition. Lot of work has been done in different part of India, however there is very limited work on pomegranate crop in central India specially Madhya Pradesh. The investigation was carried out on a seven-year-old Bhagwa plantation at a distance of 12 by 8 feet. Eighteen treatment combinations were used in the experiment, with three levels of the recommended dose of fertilizers (100%, 75%, and 125%), three levels of NAA (0 ppm, 10 ppm, and 20 ppm), and fertigate applied at intervals of 15 and 30 days with three replications using asymmetrical factorial RBD. The analysis showed that minimum days to bloom appearance, days to fruit initiation, and maximum juice (%) as well as aril (%) were observed under T13 (100% RDF + NAA 20 ppm + fertigate) at a 15-day interval. while the maximum plant height, chlorophyll content, days to bloom appearance, and days to fruit initiation were observed in treatment (125% RDF + 20ppm NAA + fertigation 15 days), while the minimum plant height, chlorophyll content, juice, and aril (%) were recorded under the combination 75% recommended dose of fertilizers + 0 ppm naphthalene acetic acid + fertigation 30 days during both years. The production and quality characteristics of pomegranates were strongly impacted by the use of chemical fertilizers (N, P, and K) as well as plant growth hormones (NAA).

Conclusion

Based on the results of this experiment, it can be determined that the combination of 100% RDF + 20 ppm NAA + 15 days of fertigation had a substantial impact on days to bloom appearance, days to fruit initiation juice (%) and aril (%) than all other treatment combinations, and the maximum plant height and chlorophyll content recorded under the combination of 125% RDF (781:313:313 g NPK per plant), 20 ppm naphthalene acetic acid per plant, and fertigation with NPK at a 15-day interval The treatment combination of 75% RDF + 0 ppm naphthalene acetic acid + fertigation with NPK at a 30-day interval had the lowest significant effect on days to bloom appearance, days to fruit initiation, plant height, chlorophyll content, juice, and aril (%) than any other combination of treatments. A considerable increase in fruit growth and quality was seen upon the application of inorganic fertilizer and naphthalene acetic acid.
