For Castanea growers who remember the ‘Half Cost, Better Castanea’ Demonstration Meeting held in Fujian Province during August of 2020, the results are now in. Under the same field management and at half the cost, RLF’s Better Castanea Foliar Program has delivered a better result and effect than the Control program.
Mid to late September is the maturing time for Castanea, so it was at this time that the RLF Technical Team revisited the fields to test the true yield and quality.
For those who need a reminder, Castanea is a member of the chestnut family.
The RLF Better Castanea Program
|Location||Shui Yuan village, Jian ‘ou City, Fujian Province|
|Crop Type||Castanea Henryi|
|Crop Nutrition Program||Application Date||Products Used and Usage Amounts|
|28th April, 2020||Foliar: Broadacre Plus 200ml + Boron Plus 50ml + Water 250kg|
|4th July, 2020||Foliar: Broadacre Plus 200ml + Boron Plus 50ml + Water 150kg|
|31st July, 2020||Foliar: Broadacre Plus 200ml + Boron Plus 50ml + Water 150kg|
- Leaf Comparison
The leaves in the control area became brittle, and the ageing leaves degenerated. Demonstration area leaves touched thickness, toughness and glossy. Meanwhile, the retention rate of ageing leaves is higher. This is vital to the accumulation of nutrients in the tree body after harvest. It will directly affect the differentiation of flower buds and the ratio of male and female flowers next year, thus improving the “only have flowers but not fruit”.
- Fruit Comparison
Fifty samples were randomly picked in the RLF-treated and Control areas respectively.
- Cost and Yield Comparison
Under the same crop management, the foliar Control scheme used regulator + boron fertiliser + micro fertiliser. The cost was 42 yuan/time/mu.
The RLF-treated demonstration area foliar scheme, used Broadacre Plus and Boron Plus. The cost was 19.5 yuan/time/mu. The cost of the RLF foliar fertiliser program was only half the cost of the Control.
|Average fruit weight(g)||Average weight (g)||Estimated yield (kg/per tree)||Estimated yield (kg/per mu)||Increased yield (kg/per mu)|
There was an average of forty trees per mu in both the Control and Demonstration areas.
It is expected to yield 433kg per mu in the Control, whilst the RLF-treated area is expected to produce 594kg per mu. This means that the yield is estimated to increase by 160kg per mu.
According to the fresh fruit purchase price of 12 yuan/kg in 2020, and after deducting the input cost (19.5 yuan/time *3 times =58.5 yuan), using RLF’s ‘Better Castanea’ crop nutrition program, the benefit per mu would increase by 1861.5 yuan.
