RLF BORON PLUS DELIVERS HIGH YIELD HONEY POMELO CROP
Healthy Early Growth and Development is the Key
Spring is when the early stage development of honey pomelo occurs. The growing of shoots, flowering and fruiting are the crucial periods for setting yield potential.

About the Crop and its Nutrition Needs

Spring is when the early stage development of honey pomelo occurs. The growing of shoots, flowering and fruiting are the crucial periods for setting yield potential.

Despite the beautiful flowers many farmers experience the problem of malformed flowers in their orchards. The malformed flowers are characterised by partial flower organ development or flower shape deterioration. This lowers fruit setting rate as well as the ability by the tree to retain nutrient.

The honey pomelo belongs to the ‘big fruit category’ and has a relatively high demand for nutrients, especially calcium, magnesium, zinc, boron and other trace elements. Boron deficiency can cause pollen grain germination and developmental abnormalities of the flower organs such as the pollen tubes. As a result, honey pomelo is severely effected and the fruit setting rate is low.

The honey pomelo production areas are mostly in southern regions of China such as Fujian, Guangxi, and Sichuan. The southern soil is mostly red, with acidic pH and low boron content. Therefore, the lack of boron in honey pomelo is a common problem. In order to check on the application effects of RLF crop nutrition products on honey pomelo, the RLF Sales Manager in Guangdong Province Shen Zhiqiang paid a visit on the honey pomelo growers in Wenfu Town, Jiaoling County, Meizhou City, Guangdong Province.

The Honey Pomelo Trial Record

Trial Dates 3rd February 2018 and 23rd February 2018
Trial Address Wenfu Town, Jiaoling County, Meizhou City, Guangdong Province
Farmers Wu Hanlin and Huang Gankun
Method Used Foliar spray with RLF Boron Plus 20ml with 40 Jin water as compared with foliar spray the competitor product 20ml with 40 Jin water
Trial Purpose Select the same honey pomelo tree to compare flower bud growth, strong flower effect and the growth of spring shoots after application of RLF Boron Plus and the competitor products.


Comparison by Leaf Width

Above, RLF-treated. Below competitor product.

The average leaf width of honey pomelo treated with the RLF Boron Plus is 7cm and the length is 13cm.

The average leaf width of the competitor product is 4.5cm and the length is 11 cm.

The side treated with Boron Plus has wider and longer leaves, which will lay the foundation for the nutrient supply to protect the swelling fruit of honey pomelo.

Comparison by Flower Buds

Below is RLF-treated. Above is competitor product.

The flower buds sprayed with the RLF Boron Plus grew evenly and full, with no abnormal flowers.

The probability of malformed flowers on the competitor product’s side of the tree is 70% – that is there are 7 inflorescence with malformed flowers per 10 inflorescence.

The comparison on 33 flower buds picked up from the honey pomelo tree.
Below is RLF-treated. Above is competitor product.

It was detected that 100% of the flower buds treated with the RLF Boron Plus reached a width of 1cm or more.

Only 60% of the competitor product flower buds reached 1cm or more.

Comparison on Style Length

Below is RLF-treated. Above is competitor product.
The average style length of those treated with RLF Boron Plus measured 1.54cm, with the average competitor product style length measuring 1.29cm.
The good performance of style can greatly improve the ability of pollination and fertilisation. It also reduces fruit drop caused by poor pollination and fertilisation.

Overall Trial Results

By foliar spraying with RLF Boron Plus on two occasions, the honey pomelo trees were rapidly replenished with nutrients. This resulted in greater leaf surface, reduced number of deformed flowers, increased pollination and fertilisation capacity and improved fruit setting rate of normal flowers.

All of these factors ensuring a good harvest in autumn.
