Abstract:
The present study investigate the assessment of growth regulators on offseason flowering in Moringa var. Jaffna. The treatments viz., T₁ – Farm Yard Manure @ 2 t/acre/year; T₂–July pruning + 0.5% Nitrobenzene (Boom flower); T₃- July pruning + MC @ 50 ppm (Chamatkar) are assessed in this research paper. T₁ recorded higher number of pods i.e.221 and lower in T₃ (181.8). T₁ recorded higher than the mean value of 198.33 pods per tree. The tree canopy ranged between 3.76 m T₂ to 4.38 m inT₁. The mean tree canopy spread was 3.97 m. The percent decrease over the farmers practice was 15.01% which might contribute to higher number of pods per tree. The TNAU technology of July pruning + 0.5% Nitrobenzene recorded the highest pod weight of 96.00 g and 23.07% percent above the farmers practice. The PAJANCOA & RI technology of July pruning + MC @ 50 ppm (Chamatkar) recorded the highest pod length of 96.60 cm and 17.08% percent above the farmers practice. The total yield per ha in farmers practice was 17.32, however the technologies T₂ recorded 18.45 t and T₃ was 15.63 t/ha. The percent increase over the farmers practice by T₂ was 6.50%, and also it was observed that the farmers practice out yielded the T₃ by 10.81%.
