Effect of Combined Application of Boron (B) Foliar Fertilizer and Micoseed Cookies (MSC) to <i>Canavalia ensiformis</i> (Jack Bean) Mother Plants on the Physiological Quality of Seeds Produced

Abstract Canavalia ensiformis is a versatile crop with high economic value, especially cultivated as animal feed. To support optimal cultivation and produce high quality seeds, optimal amounts of fertilizer and planting medium were key factors to support plant growth. The objective of this study was to evaluate the physiological quality of the mother plant crop Canavalia ensiformis seeds by administering different doses of B fertilizer in combination with MSC diameter. This study used a 4x3 factorial randomized block design with four replicate blocks based on the combination of different B fertilizer dosages and MSC diameter in each block: B dose: 0, 23, 46, 69 mg L -1 , MSC diameter: 4, 5, 6 cm. From the research results the conclusions can be drawn: the combination of treatment with boron fertilizer at a dose of 46 mg L -1 (P3) combined with MSC with a diameter of 5 cm (M2) gave a positive response to seed production, weight of 1000 grains, germination test, vigor index of Canavalia ensiformis and can speed up the harvest time only 4-months after planting time and produces large size Canavalia ensiformis seeds.
