Abstract

Custard apple is a very important dry land fruit tree of India. Now-a-days, this crop is becoming popular and commercial. Due to imbalanced nutrition, diseases and pest attack and lack of adoption of advanced technology or improved production techniques the productivity of custard apple has become very low. Among these factors, probably nutrition is a key factor affecting the productivity of custard apple trees. Imbalanced and non-judicious use of chemical fertilizers is a common practice adopted by the farmers. The use of organic fertilizers with inorganic fertilizers as a supplement is a new approach to maintain a balance, regulate cropping and with a view of getting higher outcome. Hence, a field experiment entitled “Effect of different combinations of organic manures and inorganic fertilizers on growth and establishment of custard apple (Annona squamosa) cv.NMK-1 Golden” was conducted during the October 2020 to February 2021, at the Central Research Farm, Sam Higginbottom Uni

Conclusion

On the basis of results obtained, it is concluded that the treatment T3 having RDF(25%) + Vermicompost (75 %) was found best in terms of growth parameters viz., plant height (30.68 cm), number of leaves per plant (25.67), number of branches per plant (2.40), plant spread (37.18 cm), stem girth (2.71 cm), leaf area (28.16 cm2), days taken to emergence of 1st new leaf after treatment (6.47 days) and chlorophyll content (35.55 %). The maximum chlorophyll content (39.55%) of custard apple cv. NMK-1 Golden was observed with treatment T3. Moreover, the treatment T3 also showed 100% establishment of the custard apple plants cv.NMK-1 Golden. On the basis of the above findings the best combination of organic manures and inorganic fertilizers was RDF (Recommended Dose of Fertilizer) (25%) with Vermicompost (75%) as observed in all the parameters of custard apple plant. However, these findings are based on one season trial. Therefore, further evaluation trials are needed to substantiate the f
