How to grow Alfalfa

Lifecycle of Alfalfa Crop. In a few words, alfalfa can be sown during autumn or spring. Suppose we sow the seeds during the spring of year 1. If all things go right, about 60-65 days later, we can normally harvest our first cut. 35-45 days later, we can harvest the second cut, and generally every 35-45 days we can harvest alfalfa cuts up until late fall (the end of October – November)

6 FAQs about [Is it okay to grow alfalfa under photovoltaic panels ]

Can PV panels be used for agrivoltaic systems?

PV panels with mirrored backings might also increase the availability of sunlight for crops by multiplying the reflection of incoming light to the ground. Further research is required to couple new PV panel technology to agrivoltaic systems. Another area of research is the development of suitable PV modules for agrivoltaic systems.

Do mobile panels increase alfalfa production?

Conclusions This study shows that over the two years of experimentation the presence of mobile panels allowed an increase in alfalfa production (+10 %) for shading percentage between 29 % − 44 % compared to a full sun situation (835 g.m −2 .year −1 ).

Are PV panels beneficial for crops?

Several factors may explain why incorporating PV panels into agriculture can be beneficial for crops. First, the light saturation point of each crop seems to be a key concept. Actually, only a small fraction of the incident sunlight is required for plants to reach their maximum rate of photosynthesis.

How do photovoltaic panels affect crops?

The main impact of photovoltaic (PV) panels on crops is their shadow, which reduces the available photosynthetically active radiation needed for photosynthesis. There is a debate about the shade ratio that is acceptable in AV systems.
