Pomegranate is known as a drought tolerant crop, yet regular irrigation is mandatory to commercial yield production.
Water levels and optimal irrigation regime depend on a plurality of factors as soil type, tree size, physiological phase and potential evaporation.
As a rule the tree needs little supplemental irrigation. The commonly used irrigation regime in pomegranate orchards relies mainly on the experience gained by growers and less on formal experiments led in Israel and/ or other countries.
- Fruit and agro-industrial crop
- Climatic change & water scarcity concerns
- Rising fertilizer & labour costs
- Leaching and washing away of nutrients by runoff
- Low water & fertilizer use efficiency
- Low productivity/ha
Need for drip
- Economic importance of pomegranate in meeting growing demand
- To conserve water, increase water & fertilizer use efficiency and optimize cane yields

- Agronomic & Technical support: Varietal selection; Pruning; Soil preparation; Crop water requirement & irrigation scheduling (depth and frequency of water application; water quality consideration, measurement of applied water) & fertigation scheduling (soil & water analysis, estimation of nutrient dose, selection of fertilizers & compatibility, application skill via drip system, foliar diagnosis for nutrient deficiencies etc); System operation (pressure reading & maintenance, valves operation, measurement of applied water) & maintenance (cleaning of filters, fertilizer tank, acid treatment, chlorination etc).
- Training & capacity building: Soil water plant relationships, drip irrigation & fertigation principles, benefits, limitations & utility; water quality & herbicide usage.
- Improved total fruit yield: Surface drip 45 to 48 tons/ha)/li>
- Yield under control plots: 25 to 35 tons/ha
- Improved fruit quality: Large & uniform size (> 450 g/fruit) and bright colour.
- Irrigation water requirement: Surface drip 4500 m3/ha ( mm/ha)
- Saving in water over conventional irrigation scheduling practice: 3000 m3/ha
- Additional area irrigated by saved water: 0.66 ha.
- Other benefits: Saving in fuel expenses, uniform flowering, higher fruit size, bright fruit colour, bold arils; improvement in fertilizer use efficiency, management flexibility, less weed growth, uniform irrigation of pomegranate on undulated terrains etc
- Drip irrigation of pomegranate in Israel is a feasible eco-technological and economically viable technology
- Use of scarce water resources sustainably in pomegranate cultivation to bring larger area under cane cultivation
- Higher productivity & improved fruit quality and increased income to farmers
- Pomegranate best management practices – Variety, Pruning, Surface or Subsurface Drip Irrigation & Fertigation scheduling
Grow More: 37% Fruit yield
With Less: Water saving 66%
