Abstract

Smallholder sago plantations generally use simple technology, resulting in the determination of harvest time based solely on the physical appearance of plants. This study aims to identify the agronomic characteristics of sago that influence starch yield. The research was conducted on smallholder sago plantations, and samples of sago plants were collected at four harvest phases based on local customs: Dewasa, Jantung, Rusa, and Bunga. Observations on agronomic เว็บสล็อต | R4shub characteristics included the number of suckers, plant height, pith diameter, number of leaves, number of leaf scars, number of leaflets, leaflet length, and leaflet width. ANOVA and multiple comparisons were utilized to identify differences between treatments in starch yield. Regression analysis was employed to establish the relationship between starch yield and agronomic characteristics, while path analysis determined the direct/indirect effects of agronomic characteristics on starch yield. The results indicated that the optimal harvest time is during the Jantung and Rusa phases. The agronomic components that significantly influence sago starch yield are pith diameter and leaf scars. According to the coefficient of determination value, the production model can be expressed as Y = -63.26 + 2.44x1 (R2=37%). To enhance starch yield, it is crucial to improve plant spacing. When the plant spacing is too close, with a population density exceeding 200 clumps/ha, overlapping leaves occur, negatively impacting sago starch formation. This negative effect intensifies with an increase in the number of leaves and the size of leaflets in terms of length and width. Keywords: sago plantations, agronomic characteristics, harvest time determination, starch yield, smallholder agriculture

Abstract

Leaf organs have an important function as a place for photosynthesis and protein biosynthesis. Photosynthesis ability can be influenced by leaf morphology such as leaf color, leaf area and thickness, number of stomata and leaf shape. Pepper leaves have a variety of shapes that can be used as characteristics of a cultivar. The study aims to obtain information on nitrate reductase activity (NRA) from the leaf morphology of several pepper cultivars planted on peat land. The study was conducted using a non-factorial completely randomized design. The treatments consisted of Bengkayang pepper cultivar leaves divided into three leaf groups (wide, medium and narrow), Indian pepper cultivar leaves and 2 wild peppers in the form of Piper retrofractum and P. colonum. Samples were taken from community plantation, the third youngest leaf of 6 pepper stalks was selected. The results showed that in the Bengkayang pepper population there was a diversity of NRA values. Pepper with the highest ANR was shown in broad-leafed and Indian Bengkayang. The NRA values of broad-leaf, medium-leaf and small-leaf pepper were 5.92; 5.90; 5.81; and 5.78 µmol/hour/gr leaf weight, respectively. In the field, leaf area is an indicator of fast or slow growth rate. The leaf size of wild pepper Piper colonum and P. retrofractum ranges from medium to narrow and has better NRA compared to narrow-leaved Bengkayang

Abstract

Efforts to overcome R. solanacearum which causes bacterial wilt (BW) in ginger in peatlands are through a strategy to suppress the initial population. One of the efforts is to use endophytic fungi (CE) as biological control agents. This study aims to examine the use of several endophytic fungi isolates from pepper to suppress bacterial wilt disease and improve the growth of ginger. The treatment of CE biological agents in the form of Aspergillus spp., Fusarium sp., T. harzianum, and T. viride to suppress wilt disease in vivo and the use of biological agents as biofertilizers in the field. The source of the pathogenic bacterium P. solanacearum was obtained from samples of wilted rhizomes from community ginger field isolated on NA media. This study was arranged based on a completely randomized design with five replications. The research variables were wilt disease severity, plant height, number of leaves, number of stems, stem diameter & rhizome weight. The results showed that R. solanacearum caused symptoms after an incubation period of 9 days after inoculation. The four CE isolates were able to suppress the symptoms of ginger wilt in the range of 70-80%. The use of CE isolate was also able to improve the growth of ginger, but it has not been followed by an increase in the production of ginger rhizomes. It is suggested that the use of CE as a biofertilizer needs to be increased in the frequency of its application.

Abstract

This study aims to test the effectiveness of chitosan compounds in controlling anthracnose disease (Colletotrichum capsici) on large chili plants (Red pepperL.). The study was conducted in September 2022-January 2023 for 4 months at Jl. Purnajaya 1, Siantan Hilir District, Kota. The study used a Completely Randomized Design with 6 levels of treatment doses, namely 0.05% chitosan, 0.10% chitosan, 0.15% chitosan, 0.20% chitosan, a negative control without treatment, and a positive control in the form of propineb 70% 2 g/l. The variables observed were disease incidence and disease severity after application of various treatment concentration levels. Data analysis used analysis of variance in the Minitab v.19 program. The results showed that the treatment of chitosan compounds on the development of anthracnose disease in the field test had no significant effect on the variables of disease incidence, disease severity, AUDPC calculations and regression. It is suspected that the absence of the effect of chitosan compounds in suppressing the development of anthracnose disease is due to the concentration given being too low so that the chitosan compound does not work effectively in protecting chili fruit

Abstract

Edamame has high yield potential; however, production in Indonesia remains limited. Edamame production on peatlands faces several obstacles, including the nature of peat, which often has low nutrient content and high acidity levels that do not support the formation of root nodules. One way to form root nodules to increase edamame productivity is to use salicylic acid and Bradyrhizobium bacteria. This study aims to determine the effects of the timing of salicylic acid and Bradyrhizobium treatment on edamame productivity in peatlands. This research was conducted in Siantan Hilir, North Pontianak, during July-September 2024. The experimental design used was a factorial RAL split-plot design consisting of two factors. The first factor is the treatment of Bradyrhizobium bacteria, and the second factor is the timing of salicylic acid treatment. There are six treatment combinations with 6 times replications. The variables observed include plant height, number of leaves, number of root nodules, root length, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. The results showed no significant interaction between salicylic acid treatment and Bradyrhizobium bacteria. Salicylic acid treatment significantly affected the number of root nodules, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. Still, it did not significantly affect plant height, leaf number, or root length. Bradyrhizobium bacteria treatment significantly affected the number of root nodules, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. Still, it did not significantly affect plant height, leaf number, or root length. The treatment of salicylic acid and Bradyrhizobium bacteria individually had a significant effect on the number of root nodules, number of pods, pod weight, and yield per plot and per hectare.
