Abstract

Khasi mandarin is commercially the most important citrus fruit in North Eastern Region of India. While significance of vegetative propagation had been established; its adoption by the nurserymen and preference by growers in this region is limited. Still, they are continuing plantation of seedlings. Prevalence of nucellar seedlings in Khasi Mandarin can be effectively explored in this aspect. Nucellar seedlings perform consistently and reproduce similarly to their mothers. Enhancing the growth of seedlings becomes essential in Khasi mandarin. The present investigation was carried out at Fruit nursery, Department of Fruit Science, College of Horticulture and Forestry, Pasighat during 2021-22 to study the Influence of media, VAM (Vesicular Arbuscular Mycorrhizae) and supplementary nutrients on growth of Khasi Mandarin seedlings (Citrus reticulata Blanco) in the nursery. The experiment was planned in two factorial CRD and replicated thrice, consisted of 12 treatments with different potting media, VAM and supplementary nutrients, and their effect was studied after transplanting to polybags till one-year of age. The results indicated that, seedlings were found to better with respect to vegetative growth parameter viz. plant height, number of leaves, stem diameter and physiological growth parameter like fresh and dry weight of leaves, stem and shoot; length of the longest root, number of primary roots, root volume. Biochemical parameters like chlorophyll ‘a’, ‘b’ and total chlorophyll; leaf carbohydrate and leaf protein. The medium combination of (M2) soil + vermicompost (2:1) with (V3)VAM (Glomus mosseae) @ 5gm and NPK 19:19:19 @ 1% had given significant results among different combination in 12 months old seedlings. This would ensure raising of seedlings more productively in shorter cycle of nursery production.

Keywords

Khasi Mandarin, Media, VAM, Nucellar seedlings

Conclusion

The study revealed that media (M2) of soil + vermicompost (2:1) with VAM (V3) of Glomus mosseae and NPK 1 % 19:19:19 (Pramukh) spraying are more preferable for reducing the nursery growth period of seedlings. Therefore, farmers or nursery man who are interested in mass multiplication Khasi mandarin through seedlings are advised to use these combination treatments (Citrus reticulata Blanco).
