An experiment was conducted at Horticultural Research Station Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, during 2009-11 to induce flowering in late autumn flush and to ensure regular cropping and sustainable yield in litchi cv. Bombai by pre-flowering pruning shoots in different months. The experiment comprised 9 (nine) treatments with 3 (three) replications, laid out in factorial completely randomised design. The results of experiment revealed that the per cent flowering shoots was maximum 65.52 per cent, highest number of fruits per tree (3061.53) and highest yield (74.07 kg/tree) was recorded with pruning shoots in the 2nd fortnight of November. Emergence of panicle was earlier nearly by 3-4 days by pruning shoots in the month of October and November. The better fruit set and the retention of fruits per panicle was observed in pruning of current season shoots in the 1st fortnight of November compared to control. The pruning shoots in first fortnight of November caused maximum fruit weight 24.22 g, fruit length of 3.94 cm and pulp weight of 18.33 g. The highest total soluble solids content 17.33 o brix with trees pruned during 1st fortnight of November and the highest total sugar content of 14.44 per cent was recorded with pruning at 2nd fortnight of October followed by pruning at 1st fortnight of November with 14.04 per cent. The lowest acidity content 0.33 per cent and highest TSS/acidity ratio (50.45) with pruning in 2nd fortnight of November. The pruning of current season shoots in 2nd fortnight of November showed highest vitamin-C content of 67.98 mg per 100g of pulp. It appears from the results that pruning current season shoots in 2nd fortnight of November found to induce flowering in the unproductive late autumn flush to ensure regular cropping and sustainable yield of litchi cv. Bombai.
