Impact of In-Situ Moisture Conservation Techniques on Yield in a Pomegranate Orchard

In-situ soil moisture conservation involves capturing rain and retaining it in soil for plant utilization which can result in better growth ultimately leading to enhanced biomass yields. Soil and Water Conservation Research Institute in Chakwal, conducted this research spread over the span of three years (2019-2021) with a focus on evaluating the effectiveness of in-situ moisture conservation techniques in a pomegranate orchard. The experiment was designed using a Randomized Complete Block Design and aimed at assessing the impact of various treatments on soil moisture content and fruit yield. The study revealed significant improvements in mean soil moisture content, with the maximum increase observed in the treatment involving the application of black sheet combined with gypsum (55% higher than the control). Additionally, the use of grass mulch with gypsum application showed a notable increase of 43% over the control. Fruit yield, a crucial parameter in orchard productivity, showed highest values in the treatment utilizing black sheet with gypsum application, resulting in a remarkable 50% increase compared to the control. Similarly, the control treatment revealed the lowest fruit yield at 16 fruits per plant. The in-situ soil moisture conservation technologies were considered suitable for Barani area conditions. The experimental findings reveal the potential of in-situ moisture conservation techniques in optimizing soil moisture levels and enhancing pomegranate fruit yield. The study provides valuable insights into sustainable agricultural practices, demonstrating the practical benefits of incorporating moisture conservation strategies for improved orchard management, economics and productivity. The in-situ soil moisture technologies have potential to increase orchards crop productivity and are viable for greater farmer adoption. It is recommended that these technologies be verified further by scientists and farmers through participatory approaches for wider promotion and adoption.
