THE USE OF KNO3 FERTILIZER TO IMPROVE THE QUANTITY AND QUALITY OF BOTANICAL SEEDS (TSS) THREE VARIETIES THE RELATIONSHIP OF VIGOR AND VIABILITY OF SHALLOTS (Allium var. ascalonicum)

The use of seed tubers as material for shallot propagation has several problems, including the low availability of TSS seeds in the market, low seed quality, low productivity, and expensiveness. One of the potential technology alternatives to be developed as seeds is the use of true shallots seeds (TSS). KNO3 is one of the best sources of potassium and nitrogen, this can be seen from the production of quantity and quality of botanical seeds (TSS = true shallots seed), accelerating shoot formation and vegetative growth by treating three varieties of shallots planted, namely 1. Sanren, 2 . Superpilip, 3 Headers. All varieties were given a dose of KNO3 fertilizer; with 4 levels, namely the first treatment without KNO3 fertilizers, the second was given KNO3 with a dose of 7 grams, 3 KNO3 a dose of 9 grams and the fourth treatment was given a dose of 11 grams, and given a growth regulator BAP with the best 250 ppm dose of treatment. Previously, all varieties were treated, starting from October 2019 to June 2020. The results obtained were 40.70 cm plant height, quality and quantity of shallot bulb seeds, 63 flower tubers, 26 lower pithy capsules, number of tubers per samples 13, tuber boot per plot 10, tuber production 18 tones h-1 in Superpilip varieties, seed weight of TSS 35 grams, percentage of seeds germinating 44%, but based on the results of the viability and vigor index analysis test 58, 00% best shallot seed from all aspects of seed analysis is the Sanren variety.
