When choosing what to plant it can seem difficult to understand what to choose. Each variety has its own characteristics with its inherent pros and cons. Different varieties do well in one area and not so well in another. To start off, The Beaumont (or 695) is the most common variety in South Africa with around 70% of all trees. The Beaumont has a good root system, a high yield but not the highest crack-out. It is a tough tree and a good base for any mac farm. It should bear fruit in 3-4 years after planting and create around 4 tons per Ha after 8-10 years. The A4 will take longer to produce nuts but the crack-out (size/quality) will be higher. The tonnage might be slightly lower than the beaumont but the bottomline can still be better.
It could seem then that you should plant a lot of different varieties to be on the safe side and mix it up as much as possible. Well, this is not true. If you do that you will run into problems. Different varieties mature at different times and drop to the floor accordingly. The Beaumont doesn’t even drop naturally but only after spraying the tree and if you spray immature nuts of other varieties those immature nuts will also drop and you loose income. The 791 is the only one that will not let its immature nuts drop even if you spray it. Therefore you can mix 791 with Beaumonts in the same row but keep the A4s in separate rows.
