Abstract. Najib GA, Mustofa, Maxiselly Y, Rosniawaty S. 2026. Flower phenology and artificial pollination timing in two parental Excelsa coffee (Coffea liberica var. dewevrei). Asian J Agric 10 (1): g100142. https://doi.org/10.13057/asianjagric/ g100142. Excelsa coffee is a cross-pollinating coffee variety whose reproductive success depends on synchronization between flower phenology and pollination timing. However, information on flower development and artificial pollination timing in Excelsa coffee remains limited. This exploratory descriptive field study aimed to determine (i) the duration required for flower buds to reach the phenologically suitable stage for pollination and (ii) the artificial pollination timing associated with more rapid progression toward early fruit development under observed conditions. Field observations were conducted at Agricultural Assembly and Modernization Agency: Industrial and Refreshing Plant, Indonesia, using two six-year-old parental of Excelsa coffee plants (n=2) that pollinated multiple times and gained 12 successful pollination flowers as the samples. Flower development was monitored from inflorescence emergence (stage 51) to early fruit development (stage 71) following the BBCH scale. Parameters observed included flower bud number, flower bud length, duration to the phenologically suitable stage, and time from pollination to initial fruit development. Artificial pollination was performed at 05:00, 06:00, 07:00, and 08:00 AM, with three pollinated flowers per treatment. Data were analyzed descriptively using means, standard deviations, and population variance, and thermal accumulation was assessed using Growing Degree Days (GDD). Results showed that flower buds required approximately 25-30 days to reach the phenologically suitable stage for pollination. 70% of buds reached BBCH stage 58 on day 25, with a mean bud length of 8.03 mm, while first flowering (BBCH 60) occurred around day 30. Flower bud length exhibited greater variability during early development and became more uniform toward later stages. Following artificial pollination, all treatments reached BBCH stage 70 by day 7; however, under the observed conditions, pollination at 08:00 AM was associated with faster progression to BBCH stage 71, with 66% of samples reaching this stage by day 13. These findings provide baseline phenological information and indicate a narrow temporal window suitable for artificial pollination in Excelsa coffee under the observed conditions.

Abstract

In recent years, productivity decline in arabica coffee has become a real issue in Indonesia. This decay has been brought about by various external and internal factors that are beyond human control. Various factors, including suboptimal cultivation practices, take part in this process. The objective of the present study was to evaluate the effect of pruning combined with foliar fertilizer application (coconut water and sugarcane molasses) and 6-benzylaminopurine (BAP) on the vegetative growth of arabica coffee plants during the production phase. The research was conducted at Ciparanje Experimental Field, Universitas Padjadjaran, using a randomized complete block design with seven treatments including a control (without pruning and foliar application), application of coconut water (75%, 750 mL L⁻¹), sugarcane molasses (2 mL L⁻¹), and BAP at 60 ppm, each applied with and without pruning, and four replications. In this research, the main parameters observed included the number and length of the lateral branches, leaf chlorophyll index, leaf area, canopy width, number of fruit clusters per branch and per tree, and coffee cherry fruit weight. It emerged that the combination of pruning and the use of sugarcane molasses at 2 ml/L significantly increased lateral branch formation, leaf area, and the number of fruit clusters per tree. The integration of pruning with foliar treatments effectively supported optimal growth of productive-phase arabica coffee plants.
