This research was aimed to know the response of flowering synchrony and seed quality of several lines of sweet corn (Zea mays subsp. mays L.) under boron fertilizer application. The research was conducted at the Experimental Garden of PT. Benih Sumber Andalan (BSA) in Dramaga District, Bogor Regency - West Java, from October 2022 to February 2023. This research used a Split Plot Design with two factors. Sweet corn line as the main plot consisted of five levels, namely BSA1 line, BSA2 line, BSA3 line, BSA4 line, and BSA5 line. The dose of boron fertilizer as sub plots consisted of four levels, namely 0, 10, 15, and 20 kg ha-1. The results showed that the BSA1 sweet corn line had the best effect on the male flowering time parameter. The dose of boron fertilizer 15 kg ha-1 had the best effect on the parameters of male flowering time , female flowering time, ASI (Anthesis Silking Interval), cob weight without cobs, seed weight per cob, number of seeds per cob, and seed germination rate. Combination treatment of BSA1 sweet corn line with boron fertilizer dose of 15 kg ha-1 is able to increase the synchronization on male flower flowering time and female flowering time.ABSTRAKSinkronisasi pembungaan dan mutu benih dalam upaya meningkatkan hasil benih jagung manis dapat dilakukan dengan mengembangkan galur-galur yang unggul dan pemupukan yang tepat.

The research was conducted in greenhouse of Agriculture Faculty, Universitas Jember, from November 2021 – April 2022. It used a completely randomized design with two factors and three replications: ameliorant materials namely organic matter (A1), gypsum (A2), dolomite (A3), and NPK fertilizer (A4). The second factor was the inoculation of growth-promoting bacteria, namely without inoculation of bacteria (P0), phosphate solubilizing bacteria (PSB) (P1), potassium solubilizing bacteria (KSB) (P2), and a combination of PSB and KSB (P3).

The research method used a randomized block design (RBD), with six combination treatments of tapping frequency and fertilization. The results showed that the highest volume of latex was produced in the S/2 d3 ET treatment of 2.5% 100% fertilization, while the variable dry rubber content (DRC), tapping frequency treatment d3 (B, D, F) produced higher DRC and was significantly different compared to tapping frequency treatment d2 (A, C, E).

Samples were taken from blocks A, B (planted in 1988) and C, D (planted in 2016). The parameters observed included the number of losses in the circle, path, and collection point of FFB, areas, plant age, and the suitability and completeness of equipment. Treatments included spraying on circles, paths, and collection points of FFB, as well as the placement of employees based on their experience level and the provision of tools.
