Effect of different orchard management practices on the growth and production of rejuvenated of pomegranates (Punica granatum L.) cv. Kandhari Kabuli

Abstract

Orchard management practices are the most important cultural tools for successful and sustainable cultivation of any fruit crop including pomegranate. Orchard management systems have an effect on growth, yield and fruit quality through their smoothening effects on the availability of nutrients, conservation of moisture and reduction of weed competition. Orchard management practices treatments viz., five orchard floor management treatments viz., T1: Grass mulch (10 cm thick), T2: Black polythene mulch, T3: Clean basin + Herbicidal treatment (Glyphosate 7ml/ litre), T4: Ridge basin + Grass mulch and T5: Control (No mulching). The results of the experiment, black several that polythene mulch proved to be most effective in increasing plant growth (51.80 cm), yield (13.05 kg/plant) of superior fruits and also in conservation of soil moisture. Grass mulch was better when compared to other orchard floor man-agement practices in terms of growth (47.00 cm) and yield (12.35 kg). The orders of the orchard floor management practices in moisture conservation are: black polythene mulch 13.51 %> grass mulch 12.38 % > ridge basin + grass mulch 9.31% > clean basin + Herbicidal treatment (Glyphosate 7 ml/litre) 9.20 %> control 7.64 %. Orchard floor management treatments did not exert any significant effect in controlling bacterial blight disease on leaf and fruit surface.

Effect of rejuvenation pruning on the growth, productivity and disease incidence in declining trees of pomegranate (Punica granatum L.) cv. Kandhari Kabuli

“…The maximum TSS: Acid ratio (42.10%) was observed in T 1 , whereas minimum TSS: Acid ratio (21.86%) was observed in T 5 (Table 3). The results are in accordance with the earlier findings that percent TSS and other physicochemical characters increased significantly with severe pruning treatments (Hassani andRezaee, 2007 andSharma et al, 2017). Disease incidence on fruit and leaf surface: The present investigation revealed that the disease incidence in the fruit and leaf surface were affected significantly by all the pruning treatments over control.…”

“…However, the effect of pruning treatments on the durations were non-significant and maximum disease incidence was recorded in T 5 (control). The results relating to the decrease in disease severity by different pruning treatments over control are in agreement with the findings of (Riedle, 2010) in grapes, (Lemus, 2010), in walnut (Yang, 2009) in persimmon and apricot Sharma et al (2017).…”
