Abstract

Rice is Indonesians' main source of nourishment. Farmers get the seeds for growing their paddy crops from both non -local rice genotypes and local genotypes. The two main consideration factors influencing the decision to use the seed varieties are high production of the varieties and customer preferences. Local rice genotypes in Kuantan Singingi Regency have potential to fulfill the เว็บสล็อต | R4shub requirements. This study aimed to ascertain the response the regional rice genotypes in Kuantan Singingi Regency to planting system technology. The experiment was designed in Split Plot Design in a Completely Randomized Design (CRD), the main plot consisted of multiple cultivation systems (Factor S) as follows: Tile system, Jajar legowo system (2:1), and Rice Intensification systems. The following genotypes were then employed in subplots using a completely randomized design (CRD): Kuning Umur Panjang (G07), Samo Putiah (G09), Limbayang (G10), Singgam Putih (G14), Pulut Kari (G16) and Kuning (G18). The findings showed that.local rice genotypes responded differently to the planting system technology. Limbayang genotype had dry milled grain weight per clump of 105.57 grams, while the Singgam Putih genotype had plant height of 141.00 cm. The rice intensification system (SRI) gave the best growth and production to Limbayang and Singgam Putih. The findings of the study can be taken into consideration for future research, such as plant breeding efforts to enhance the traits of local rice genotypes.

Abstract

In Indonesia, chili is a valuable horticultural commodity. On the other hand, chili productivity in West Sumatra shifted from time to time. One of the factors causing unstable chili production is pests. Genotype, environment, and the interaction of genotype and environment all impact plant productivity. Plant productivity increases as the environmental conditions surrounding the plant are favorable, and nutrient availability is sufficient to meet the needs of plant life. Environmental factors such as nutrient availability and genetic factors such as plant genotypes significantly impact crop production. The aim of the study was to determine the best growth and yield of several genotypes of local West Sumatra chili fertilized with potassium at various doses. The study employed a completely randomized design (CRD), 2 factor,  replicated three times. The first factor was the chili genotype consisting of 6 local red chilies ie. Pesisir Selatan, Ateng Pasaman Barat, Dhamasraya 2, Ateng Maninjau,  Tanah Datar and Kampung Manangah Solok Selatan. The second factor was the dose of potassium fertilizer (K2O) consisted of 180 kg/ha, 240 kg/ha and 300 kg/ha. The native chili genotype Ateng Pasaman Barat produced the highest crop yield when fertilized with potassium at a dosage of 300 kg/ha. A potassium fertilizer dose of 300 kg/ha generated the best growth and yield, as shown by higher plant height, number of fruits per plant, and fruit weight per plant. Keywords: local chili, genotype, potassium, plant growth.

Abstract

Pakchoy is a leafy vegetable that is great demand by Indonesians. The increase in population has had a major impact on agricultural land, which has encouraged an urban farming system, using polybags for crop production. The use of soil media in polybags often experiences compaction and lack of nutrients, so it is necessary to modify the composition of the planting media and put additional fertilization. This research was conducted to evaluate the response of pakchoy to local microorganisms based on rice waste and to determine the best composition of growing medium for pakchoy plants. This study used a completely randomized design (CRD) with 2 factors. The first factor was the local microorganism (LMO) doses of rice waste consisted of 4 levels, namely 0 ml, 500 ml, 1000 ml, and 1500 ml per plant. The second factor was the composition of the planting medium (Soil : Sand: Cow Manure) at 4 levels, namely Soil 100%, 1:1:1, 1:1:2, 1:1:3. Data were statistically analyzed with ANOVA at 5% level. Mean separation was tested further with Duncan Multiple Range Test. The results showed that the LMO 0 ml and 500 ml performed higher effects on plant height, number of leaves, plant fresh and dry weight, root fresh and dry weight, and root length compared to the application LMO at 1000 ml and 1500 ml. The highest plant fresh weight was 193.1 g at 0 ml LMO, followed by 160.35 g at 500 ml LMO.   The composition of the planting medium 1:1:1 and 1:1:2 resulted in a higher number of leaves, plant dry weight, and root weight than other treatments. Incorporating a high portion of manure into the pakchoy planting medium was not beneficial. All growth variables and yield were higher compared to the control medium (soil 100%).  Key Words: pakchoy, local microorganism,  planting media

Abstract

The uses of liquid organic fertilizer (LOF) have been increasingly practiced in organic vegetable to increase the effectiveness of solid organic fertilizer application. Farmers can produce LOF by using locally available green biomass in the surrounding production areas, including leaves of Leucaena leucocephala (Lam) de Wit. This experiment aimed to determine the best concentration of Leucaena leaf-based LOF on เว็บสล็อต | R4shub growth and yield of Pak Choi (Brassica rapa Subsp. Chinensis). An experiment was arranged in Randomized Complete Design with seven replicates. Treatments are several concentrations of Leucaena leaf-based LOF, 0%, 25%, 50%, 75% and 100%.  Although, the concentration of 50% was likely able to increase shoot length, leaf area and leaf greenness of Pak Choi, but the effects of Leucaena leaf-based LOF on leaf numbers, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight of Pak Choi were insignificant.  Consistency effects of Leucaena leaf-based LOF in the production of Pak Choi should be re-evaluated

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

The impact of Azolla compost (AC) substitution for synthetic N fertilizer (NF) on nitrate leaf content and agronomic performances of green onion in Ultisols have not been well understood. Therefore, this study aimed to assess the effects of equal replacing NF with AC on growth, yield, and nitrate accumulation in the green onion leaf. The polybag trial was performed in June 2020 on the crop research farm of the Agriculture Faculty in a completely randomized design with six treatments in five replications. เว็บสล็อต | R4shub Green onion was subjected to five 92 kg ha−1 N equal combinations of NF and AC, i.e., NF100 (100% NF+0% AC), NF75 +AC25 (75% NF+25% AC), NF50 +AC50 (50% NF+50% AC), NF25 +AC75 (25% NF+75% AC), and NF0 +AC100 (0% NF+100 % AC) and no NF and AC as a control. Results demonstrated that NF+AC treatments significantly improved plant height, leaf number, tiller number, stem diameter, and plant fresh weight. Treatment of NF25+AC75 resulted in similar responses to the recommended dose of N fertilizer, as evidenced by plant height, number of green leaves, root fresh weight, shoot dry weight, tiller numbers per hill, stem diameter, shoot fresh weight, and plant fresh weight. Lower leaf nitrate contents occurred under increased substitution of NF with AC. Thus, partial substitution of NF with AC could be a sustainable option for improving growth and yield while reducing nitrate accumulation in the leaf of green onion in Ultisols.
