This experiment was conducted to evaluate the influence of different harvest timings on shallot yield and bulb characteristics, focusing on the Indian Variety, and to provide insights into optimizing shallot cultivation practices. The experiment was carried out at MARDI Serdang, employing a randomized complete block design with four replications. Consumption bulbs of the Indian Variety were harvested at five different time points: 45, 55, 65, 75, and 85 Days After Planting (DAP). Data analysis was performed using SAS version 9.4, with Duncan New Multiple Range Test (DNMRT) for specific differences. The highest yield was recorded at 65 DAP, with a dried bulb weight of 13.3 kg per plot, equivalent to 6.6 tons per hectare (t/ha). Harvesting before 65 DAP resulted in diminished yields due to bulbs still in the growing stage or delayed germination. Harvesting beyond 65 DAP also led to reduced yields, primarily caused by an increased number of rotten bulbs. Furthermore, the study revealed that the harvested shallots could be categorized into two types: single and aggregate bulbs, with each type constituting approximately 50% of the total. Single bulbs were larger than aggregate bulbs, and the 75 DAP and 65 DAP harvests produced the heaviest and widest bulbs for both categories. The findings suggest that Indian Variety shallots are best harvested at 65 DAP to achieve optimal yields. Harvesting before or after this critical period significantly impacts yield. Additionally, the use of consumption bulbs as planting material may result in the development of two distinct bulb types: aggregate and single bulbs. This study provides valuable insights into shallot cultivation practices and can guide efforts to enhance shallot production and food security.

Abstract

This experiment was conducted to evaluate the influence of different harvest timings on shallot yield and bulb characteristics, focusing on the Indian Variety, and to provide insights into optimizing shallot cultivation practices. The experiment was carried out at MARDI Serdang, employing a randomized complete block design with four replications. Consumption bulbs of the Indian Variety were harvested at five different time points: 45, 55, 65, 75, and 85 Days After Planting (DAP). Data analysis was performed using SAS version 9.4, with Duncan New Multiple Range Test (DNMRT) for specific differences. The highest yield was recorded at 65 DAP, with a dried bulb weight of 13.3 kg per plot, equivalent to 6.6 tons per hectare (t/ha). Harvesting before 65 DAP resulted in diminished yields due to bulbs still in the growing stage or delayed germination. Harvesting beyond 65 DAP also led to reduced yields, primarily caused by an increased number of rotten bulbs. Furthermore, the study revealed that the harvested shallots could be categorized into two types: single and aggregate bulbs, with each type constituting approximately 50% of the total. Single bulbs were larger than aggregate bulbs, and the 75 DAP and 65 DAP harvests produced the heaviest and widest bulbs for both categories. The findings suggest that Indian Variety shallots are best harvested at 65 DAP to achieve optimal yields. Harvesting before or after this critical period significantly impacts yield. Additionally, the use of consumption bulbs as planting material may result in the development of two distinct bulb types: aggregate and single bulbs. This study provides valuable insights into shallot cultivation practices and can guide efforts to enhance shallot production and food security.
