Abstract

The results of the present investigation indicated that, different levels of pruning severity viz., 50%, 30% and 10% and planting density viz., D1: 2.0 m × 1.0 m, D2: 2.0 m × 2.0 m, D3: 2.0 m × 3.0 m, D4: 2.0 m × 4.0 m, D5: 6.0 m × 6.0m highlight the significant effect on vegetative growth of newly planted Guava (Psidium guajava L.) cv. Allahabad Surkha under open based environment condition. The results of the study revealed that among the various pruning based treatment combinations the best 10% and 30% pruning intensity proved significantly superior over other pruning treatments for vegetative growth parameters. On other hand the results of the research study showed that among the various planting density treatments, the density i.e. D4: 2.0 m × 4.0 m, D5: 6.0 m × 6.0m conclude the significant effect and found more superior over other pruning treatments for their vegetative growth performance during rainy and winter season based research experiments. The interaction effect of different levels of pruning intensity and planting density was also found significant on vegetative growth parameter of Guava cv. Allahabad Surkha. The maximum increase plant height (cm), number of leaves per plant, no. of branches per plant, plant spread (cm) (E-W and N-S), days to 1st emergence of new shoots per plant (in days), stem girth (cm), stem length (cm), leaf area (cm2) and LAI (Index %) was recorded best with T19 (P3 10% + D4D4: 2.0 m × 4.0 m) and T20 (P310% + D5 6.0 m × 6.0 m). It is concluded from the results obtained in research findings that 10% and 30% pruning intensity and planting density D5 6.0 m × 6.0 m and D4 2.0 m × 4.0 m proved as best in terms of growth parameters of Allahabad Surkha Guava in Prayagraj Agro-Climatic region.

Conclusion

It is concluded from the results obtained in research findings that 10 and 30% pruning intensity and planting density i.e. D5 6.0 m × 6.0 m and D4 2.0 m × 4.0 m was found to be most effective to improve growth parameters like plant height (cm), number of leaves per plant, no. of branches per plant, plant spread (cm) (E-W and N-S), days to 1st emergence of new shoots per plant (in days), stem girth (cm), stem length (cm), leaf area (cm2) and LAI (Index %) of Guava cv. Allahabad Surkha.
