Abstract

Limapuluh Kota Regency and Payakumbuh City, West Sumatra Province are the centers for the cultivation of Payakumbuh tobacco plants. The average Payakumbuh tobacco production is still low, namely 0.701 tonnes/ha. One of the causes of low productivity is disease caused by the cracker virus. This research aims to see the effect of naturally infected cracker virus infection on the growth and production of tobacco plants. This research is an observational study, carried out from June to September 2023, at the Payakumbuh State Agricultural Polytechnic experimental garden. The data obtained were processed using the T test at the 5%, level using the Statistical Program for Social Science (SPSS) Version 23 software. From observation and data processing it was found that cracker virus infection caused low levels of chlorophyll A, high levels of chlorophyll B and total leaf chlorophyll levels. plant, leaf length, petiole length, leaf length, leaf width, leaf fresh weight, and root fresh weight, but had no effect on the number of leaves and leaf thickness compared to uninfected plants. From this it can be concluded that cracker virus infection can reduce the growth and yield of Payakumbuh tobacco.

Abstract

Coffee is an important agricultural commodity with increasing global demand, so optimizing the growth of coffee seedlings, especially during the seedling phase, is crucial to increase productivity. The use of natural plant growth regulators offers an environmentally friendly and economical solution. This study aims to evaluate the effect of natural plant growth regulators from onion extract and bean sprout extract on the growth of robusta coffee seedlings (Coffea canephora L.) during the seedling phase. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control, onion extract, and bean sprout extract. The parameters measured included plant height, stem diameter, and number of leaves for six weeks. Data were analyzed using ANOVA and BNT test at the 5% level. The results showed that both natural plant growth regulators significantly increased the growth of coffee seedlings compared to the control. Bean sprout extract gave the best results for plant height (16.75 cm), while onion extract was superior in increasing stem diameter (4.65 mm) and number of leaves (12.20). Statistical analysis confirmed significant differences between treatments and controls for all parameters. Thus, the use of onion and bean sprout extracts as natural growth regulators has proven effective in increasing the growth of coffee seedlings in the seedling phase, offering an environmentally friendly and economical alternative for optimizing the growth of coffee seedlings.

Abstract

Tissue culture techniques provide an alternative to vegetative plant propagation efforts in conservation efforts for Karamunting, the existence of which is becoming increasingly rare. The explant as the material used is the result of in vitro germination using several concentrations of GA3. This research was structured in the form of a factorial experiment with a completely randomized factorial design (RAL) with 2 factors. The first factor is the BAP concentration with three levels, namely B1 = BAP 0.5 B2 = BAP1 ppm and B3 = BAP 1.5 ppm. The second factor is the concentration of TDZ with three levels, namely T1 = TDZ 0 ppm, T2 = TDZ 0.25 ppm and T3 = TDZ 0.5 ppm. The results of the research showed that there was an interaction between the growth regulators BAP and TDZ on the percentage of live explants and the height of karamunting explants. In terms of the percentage of live explants, giving BAP 0.50 ppm without TDZ is the best concentration with a live percentage of 100%. Treatment of 1 ppm BAP and 0.25 ppm TDZ produced the highest shoots, namely 2.83 mm. The time of emergence of shoots and the number of shoots per explant had no interaction and the influence of a single factor, several concentrations of BAP and TDZ.
