Abstract

The purpose of this research is to determine the growth components and productivity of three corn varieties (Zea mays L.) in response to the frequency of water irrigation. The treatments were arranged in a two-factor factorial design within a Randomized Complete Block Design (RCBD). The first factor was the frequency of water irrigation, consisting of 3 treatment levels: once a day (F1), every 2 days (F2), and every 3 days (F3). The second factor was the variety factor (V), comprising 3 varieties: Bonanza F1, hybrid variety Pertiwi 5, and variety Bisi 18, resulting in 9 treatment combinations. Each treatment was replicated three times, yielding a total of 27 experimental units. The parameters observed in this study included plant height, leaf count, stem diameter, flowering age, cob length, cob diameter, and cob fresh weight. The results of the research indicate that the frequency of water irrigation significantly affects the leaf count at 14 days after sowing (HST), stem diameter, cob length, cob diameter, and cob fresh weight. Meanwhile, the variety factor significantly influences plant height and leaf count at 14 HST and post-flowering, stem diameter, cob diameter, and cob fresh weight. The interaction between the frequency of water irrigation and variety has a significant impact on stem diameter, cob diameter, and cob fresh weight. The best varieties for all frequencies of water irrigation are Pertiwi-5, and varieties tolerant to drought stress are Pertiwi-5 and Bisi-18.

Abstract

This research was conducted at the Dryland Laboratory of Nusa Cendana University Kupang from September to December 2022. The purpose of this study was to determine the effect of interaction of doses of solid bokashi fertilizer made from a mixture of kirinyu and banana stem and hormonic concentration on the growth and yield of Cauliflower and determining the combination of those interaction that provides the best growth and yield of Cauliflower plants. This research was a factorial experiment, using Randomized Complete Block Design (RCBD) with three blocks and consisting of nine treatment combinations per blocks. The observed variables were plant height increse (cm), increase in leaves number, increase in stem circumference (cm), gross weight (g) and net weight (g). The observation data were analyzed by analysis of variance (ANOVA) and and followed by DMRT test (significant level 0.05%). The results showed that the interaction between the application of doses of bokashi and hormone concentration significantly affected the increase in height, increase in leaf number, and net fresh weight of cauliflower plants. The combination of treatment doses of bokashi at 10 tons/ha with a hormone concentration of 8 cc/L was the best interaction, with a net fresh weight of cauliflower plants reaching 265.71 g/ plant.
