Agronomic practices and bio-stimulants for persian lime (Citrus latifolia Tan.) production in Mexico

Abstract

Objective: To evaluate biostimulants and cultural practices for floral induction in Persian lime (Citrus x latifolia Tanaka ex Q. Jiménez) to obtain production during the winter season, when the highest price in the market is offered with. Design/methodology/approach: From July to September period, biostimulants and cultural practices were applied to six-year-old trees with different treatments as follows: 1. Pruning only, 2. Pruning + urea, 3. Pruning + urea + ringing, 4. Pruning + biofol® + ringing. Additionally, during September, two more treatments were included: 5. Pruning + calcium prohexadione, and 6. Pruning + Citomax®. The design used was randomized blocks with four repetitions. The experimental unit was one lime tree. Flowering, yield, physical-chemical quality and cost-benefit ratio were evaluated. Results: The outstanding effect of pruning and the effect of nitrogen were confirmed with the foliar application of granulated urea (6.0 kg ha-1) during the period from July to September, obtaining an average yield of 23 t ha-1 during the harvest from December to March, with a B/C 2.5 ratio. The quality of the fruit was kept within the NMX-FF-077-1996 Mexican standard. September applied Pruning + Citomax® (cytokinins) showed a yield of 30 t ha-1, with a B/C 3.1 ratio. Findings/conclusions: Pruning + nitrogen, and pruning + cytokinins induce flowering and produce Persian lime with the best winter yields.

Assessment and selection of flowering inducers to increase productivity of mango cv. Ataulfo (Mangifera indica L.)

“…Ataulfo, it has reduced the vegetative growth and increased flower budbreak under the edaphoclimatic conditions of Nayarit (Pérez-Barraza et al, 2016). On the other hand, cytokinins have promoted greater flowering in fruit trees such as mango and Persian lime (Moreira et al, 2002, Ambriz et al, 2021. However, the inducers show different effects based on edaphoclimatic conditions, nutritional status of the tree, and others (Singh, 2013).…”
