Abstract
In ber (Zizyphus mauritiana Lamk.), budding has been found to be the best method for commercial multiplication.
However, its degree of success depends on various factors like time of budding, condition of budding, varietal compatibility, etc.
For commercial multiplication of ber in an area, such factors to be standardized for getting maximum success.
With the view to above objectives, the study was made at the Regional Research Station, Jhargram, West Bengal of Bidhan Chandra Krishi Viswavidyalaya where the climate is dry sub-tropical in nature.
To know the cultivars compatibility with the local rootstock (Zizyphus rotundifolia), ten cultivars viz., Banarasi Karka, Chhuhara, Dandan, Ilachi, Gola, Jogia, Kaithali, Mundia, Seb and Umran were patch budded on 25th June in 2004 and 2005. The cultivars Ilachi and Gola showed the best compatibility with the local rootstock as it resulted in 100% success with maximum in budling growth while Banarasi Karka gave lowest of 70% success.
As Banarasi Karka is one of the good popular cultivar in West Bengal, an attempt was made to improve the grafting success by using 50 and 75% shed-net.
The study indicated that the budded scion of Banarasi Karka performed best in open condition than under shed-net.
To know the best time for budding under nursery (seedlings grown in polybags) and open field condition, budding operation was carried out in 12 months of 2004 and 2005 using one year old seedlings in both the cases.
Results indicated that the month of May, June and September were the best time for in situ budding as it showed cent per cent success with maximum plant growth while for polybags grown seedlings in the nursery, the month of May and June were only the good time with 75 to 85% success.
The rate of plant growth after budding was more in open field (in situ budding) as compare to nursery condition.
