Irrigation for late season perennial fruit crops during drought conditions

As New Jersey continues to experience record low precipitation levels since September, the state Department of Environmental Protection has declared a drought warning throughout the state. It is important to note that the drought warning does not call for any mandatory water use restrictions or bans. However, if the drought conditions worsen, the state may implement stricter measures to prevent further losses.

We have received many questions from growers, most who have completed harvesting for the season, on whether plants should still be receiving irrigation. Our recommendation is to continue to irrigate plants until they defoliate. For perennial fruit crops, in the fall months flower buds are forming for the next year’s crop. The leaves that remain on the tree are actively working to photosynthesize, converting light into energy the plant needs to grow.

Once leaves begin to turn yellow, brown, and drop off, you can stop supplemental watering. However, if you are in a prolonged drought, as we are currently, there are some factors to consider. For perennial crops that overwinter, severe drought can compromise their ability to store sufficient reserves, which can lead to reduced vigor and potential losses during the winter. It can be the case that during periods of drought, plants may invest more energy into developing deeper root systems; however, over a prolonged period of time, persistent stresses can hinder root development, which can negatively impact water intake and nutrient availability. Additionally, whereas hydrated soils can buffer the penetration of freezing temperatures through the soil surface, dry soils do not offer the same protection, and freezing temperatures can penetrate deeper.

There are several strategies that can be adopted to mitigate the impact of drought on fruit crops.

  • A proper irrigation schedule that includes supplemental watering during growth stages can help alleviate drought impacts and stress. When possible irrigate trees through leaf drop, and avoid irrigation on warm days (60°F and higher).
  • Mulch can be applied around plants to help conserve soil moisture and reduce evaporation.
  • Soil sensors equipped with data loggers can be deployed in the field to measure soil moisture and water stress and report measurements to a computer or mobile device.
  • Regularly monitoring your crop for signs of drought stress including wilting, leaf curling and discoloration, and reduced growth, is critical for timely intervention and applying appropriate measures.

The Rutgers Agrivoltaics Program launches a new website

The Rutgers Agrivoltaics Program is a multidisciplinary group of Rutgers faculty and staff committed to designing and conducting applied agrivoltaics research and outreach for stakeholders in New Jersey and throughout the region.

The Rutgers Agrivoltaics Program (RAP) was initiated over 3 years ago with the signing and passage of the Dual Use Solar Act by the New Jersey legislature. In 2023, Agrivoltaics research installations were established at three Rutgers-New Jersey Agricultural Experiment Stations (NJAES). One at the Clifford E. and Melda C. Snyder Research and Extension Farm in Pittstown, NJ; one at the Animal Farm on the Rutgers New Brunswick (SEBS) Campus, and one at the Rutgers Agricultural Research and Extension Center (RAREC) near Bridgeton, NJ. Members of the Rutgers RAP Team in collaboration the New Jersey Board of Public Utilities, NJ Department of Agriculture, and NJ-DEP are now in the process of implementing the Dual-Use Solar Energy Pilot Program.

The agrivoltaics research at the Rutgers Agricultural Research and Extension Center (RAREC) near Bridgeton, New Jersey has been designed to study the effects of agrivoltaic (AV) systems on the production of specialty crops and soybeans. This year eggplant, pepper, fresh-market tomatoes, and soybeans are being grown under three three different treatments: single-axis tracking array with one row of panels, single-axis tracking array with two rows of panels, and no panels (conventional production as a control) to determine the effects caused by the presence of the panels on specialty crop and soybean plant growth and yield.

At the Clifford E. and Melda C. Snyder Research and Extension Farm in Pittstown, NJ the effects of a single-axis tracking array with one row of panels on hay production is being studied.

At the Rutgers SEBS Campus Animal Farm in New Brunswick, New Jersey, which hosts equine and livestock facilities, the AV research has been designed to study pasture forage production and animal grazing patterns in combination with vertical bifacial solar panels.

Stakeholders interested in keeping up the what’s going on can now subscribe to the new website and have information send directly to their email account. Just go to our contact page and follow the instructions to subscribe! 

The Rutgers Agrivoltaics Program in collaboration with the American Farmland Trust will be holding upcoming workshops for those stakeholders in New Jersey interested in learning more. Please click here for more information on these upcoming events.

Agrivoltaic farmer trainings in New Jersey!

The Rutgers Agrivoltaics Program and the American Farmland Trust are excited to host our inaugural agrivoltaics farmer trainings in New Jersey! This Technical Assistance Program for Agrivoltaics (TAPAS) will introduce the dual-use of land for both agricultural and solar energy production, and explore the opportunities it may present for greater farm viability in New Jersey.

There are three training events, but due to limited capacity, we are encouraging participants to only register for one training session so we may train as many producers as possible. The in-person events have a capacity of 20 participants. Register today to secure your spot as soon as possible! While these trainings are exclusively held for farmers and ranchers, we will have other opportunities in the future for non-farmer participants to learn from our team of experts.

Training Opportunities

Session 1: Full-day training intended for specialty crop farmers on Tuesday, August 13, 2024 at the Rutgers Agricultural Research and Extension Center, 121 Northville Rd, Bridgeton, NJ 08302

Session 2: Half-day training intended for livestock producers or those who focus on grazing and forage on Tuesday, August 27 at the Round House next to 65 Sheepfold Lane, New Brunswick, NJ 08901
