Nousbo Jumbo Tabs evaluation results for Lime Tree in Mexico. Research Summary
(Summary of the study of Nousbo Jumbo Tabs effect on Lime Tree growth and yield performances in Mexico)
Nousbo Jumbo Tabs NPK/MgO (13-11-2-5 + microelements + NPS) is a slow release nugget type fertilizer for tree, shrub and vine, that reduces labor costs by slowly releasing nutrients around the root zone for about 6 month. This fertilizer provides nutrients needed for growth and production of high quality fruits. In order to determine the effect of Nousbo Jumbo Tabs on the growth and yield of Lime Tree, the product was evaluated for its efficacy as one-time application product for complete nutrient supply for Lime Trees from October 2019 to December 2019 in Tecoman town, Colima State, Mexico.
(Lime Tree)
Nousbo Jumbo Tabs (27g) were manually applied once at the beginning of the test by burying tabs at a rate of 1 tab per hole, 20 tabs per tree evenly distributed around the dripping areas of the tree foliage, which is 540g per tree in total. No other fertilization was performed to any group during the time of the study. Conventional fertilizer used for this experiment was the granulated solid inorganic macronutrient fertilizer (12-8-16 +3 +TE) at the rate of 1000g per tree. Selected trees were located in the same area and had same height, comparable shape and size. Results are summarized in the following table.
Yield of Lime Tree affected by various kinds of treatments
The application of Jumbo Tabs showed statistically significant effect on the yield of Lime Trees. With Jumbo Tabs fertilization, the buds were bigger and more resistant to falling-off. Lime tree blooming in the Jumbo Tabs group started 1 week before the control group, which was immediately perceived by the farmer as a great sign of efficacy. More flowers per tree were found with more retention at the tree stems and branches. For the first fruit harvest period, farmer reported an increase of 1.2 Kg more fruit per tree (+22.5%) in the Jumbo tab group vs control. This means the average fruit obtained in the Jumbo Tabs group was 5.6 kg/tree while only 4.34 kg/tree were obtained in the control fertilizer group. For the second harvest period farmer reported 10.3 kg of fruit for the Jumbo Tabs group and only 9.8 kg per tree in the control group (+4.85% yield with Nousbo product). For the third harvest period farmer obtained 4.0kg per tree with Nousbo fertilizer treatment while only 3.8kg with the control group (+5% yield with Nousbo fertilizer).
(Lime Tree farm in Mexico)
Based on the results of the study, Nousbo Jumbo tabs is established as an efficient fertilizer suitable to be successfully used in the Mexican lime tree strain, showing a better performance when compared to the local fertilizer (both are SRF) during the entire test period. Even though both fertilizers are recommended to be applied every three months, it was very notorious that the farmer required to use around 50% less fertilizing with Nousbo Jumbo Tabs when compared with Control Fertilizer, obtaining superior results. The overall appearance, heath status and phenology of both groups was similar, but the final yield was superior in all Nousbo trees after 3 cuttings.
