Abstract

This study aimed to analyze the response of growth and production of Median potatoes to the application of various doses of Phonska NPK fertilizer in Rurukan Village, North Sulawesi Province. This research was conducted from August to November 2020 in Rurukan Village, East Tomohon District, Tomohon City. The design used was a Randomized Completely Blocked Design (RCBD) with six (6) treatments and three (3) replications consisting of P1 Fertilization Treatment (150 kg/ha), P2 NPK Fertilization Treatment (300 kg/ha), P3 NPK Fertilization Treatment (450 kg/ha), P4 NPK Fertilization Treatment (600 kg/ha), P5 NPK Fertilization Treatment (750 kg/ha) and P6 NPK Fertilization Treatment (900 kg/ha). The results showed that (1) the treatment with Phonska NPK fertilizer at a dose of 450 kg/ha had a significant effect on the growth and production components of the Medians potato plant in Rurukan Village, North Sulawesi Province and (2) the highest plant productivity was obtained in the treatment of Phonska NPK fertilizer with dose 450 kg/ha = 18, 11 tons/ha.

Abstract

This study aims to determine the interaction of varieties and drought stress on the growth and yield of two varieties of soybean (Glycine max (L.) Merill). This research was carried out using polybags in the greenhouse of the Faculty of Agriculture, Sam Ratulangi University with the experimental design used in this study was environmental design and treatment design was Completely Randomized Design (CRD). Research data from all observational variables were analyzed by analysis of variance ANOVA and if there was a difference between treatments, it was continued with the 5% BNT test. The results of this study indicate that the character of soybean harvesting age is influenced by the interaction of varietal factors and drought stress factors. Drought stress factors affect the character of plant height, number of main branch books, number of pods planted, and number of seeds planted. Varieties and drought stress factors did not affect the observed characteristics of the first flowering age, the number of root nodules, the number of empty pods, and the weight of 100 seeds per plant.

Abstract

This study aims to: (1) determine the content of sulforaphane in several types of broccoli sprouts. (2) Knowing the difference in sulforaphane content in the combination of NAA, BAP and types of broccoli grown on MS media; (3) knowing the difference in sulforaphane content in the combination of NAA and types of broccoli sprouts grown on MS media; (4) knowing the difference in sulforaphane content in the combination of BAP and the type of broccoli sprouts grown on MS media. This study used a completely randomized design (CRD) arranged in a factorial manner, namely factor A: NAA 0, 0,5, and 1 ppm. B: BAP 0, 1, 2 ppm and C : 2 Types of Broccoli. The variables observed were: germination time, germination weight, and sulforaphane content. The data were analyzed by analysis of variance and continued with the 5% BNT test. The results showed that germination time began to appear on day 3 and all seeds germinated. Sprout weight varied greatly, and the combination of treatments N1, B0 and BR2 gave the highest average weight and calculated concentration (ENT) of sulforaphane, followed by treatments N0B2BR2 and N0,5B0BR1.
