Abstract:
A field experiment entitled “Response of Salicylic acid and Triacontanol on Growth, Yield and Quality of Ber (Ziziphus mauritiana Lamk) cv. Gola” conducted during 2020-21 at instructional Farm, Department of Horticulture, College of Agriculture, Ummedganj (Agricultural University, Kota). It consisted of 16 treatment combinations with four levels of salicylic acid (control, SA @ 100, 150 and 200 ppm) and four levels of triacontanol (control, TRIA @ 5.0, 7.5 and 10.0 ppm) and replicated thrice in Factorial Randomized Block Design. The application of salicylic acid @ 150 ppm among the different concentrations proved significantly superior over rest of the treatments in respect to growth parameters viz. tree spread E-W (6.35 m) and N-S (6.10 m), canopy volume (2.99 m³), shoot length at 30, 60 and 90 DAS (108.93, 117.83 and 120.66 cm), shoot diameter at 30, 60 and 90 DAS (6.09, 7.72 and 8.46 mm), per cent growth (12.56%), minimum days taken to flower initiation (12.01) and per cent fruit set (11.38%), maximum fruit retention per cent (54.55%) and minimum fruit drop per cent (38.95%) while, duration of flowering and days taken to maturity were found non-significant. This treatment also gives maximum fruit weight (27.58 g), yield plant^-1 (13.62 kg) and yield ha^-1 (3787 kg).
