Growth, yield and quality of phalsa (Grewia subinequalis) with pruning intensity and nitrogen levels in sodic soil
Abstract
The experiment was conducted during two consecutive years of 2007–08 and 2008–09 with four levels of pruning (P0:control, P1: 30 cm, P2: 60 cm, and P3: 90 cm above the ground level) and four levels of nitrogen (N0: control, N1: 40 g, N2: 80 g and N3: 120 g plant−1) in phalsa (Grewia subinequalis D.C.) under sodic soil conditions of Lucknow (Uttar Pradesh). Mean data revealed that maximum shoot length (2.09 m) was recorded withtreatment combination P0N2, while maximum plant spread (2.01 m), number of canes bush−1 (18.47), number of fruits bush−1 (1478) and yield bush−1 (0.825 kg) were recorded with P3N2 treatment. However, the highest average values of 100-fruit weight (61.72 g) in P1N2, juice (54.30%) in P1N1, TSS (17.7 0B) in P3N3, acidity per cent (4.42) in P2N1 and ascorbic acid (38.65 mg 100−1 g) in P2N2 treatment were recorded. Overall, treatment combination of P3N2 (90 cm pruning + 80 g N bush−1) performed better.
