Abstract

Black pepper cultivation at different land backgrounds and fertility can affect crop productivity. This study aims to determine soil-plant nutrients for three pepper farms based on crop ages and the correlation of selected physical and chemical properties. Samples were collected in Kapit, Bintulu, and Sri Aman and analyzed for physical and chemical properties. Soil nutrient in Bintulu (6 months old) has revealed higher soil pH (4.95) with higher Fe (0.21 g/kg) and N (1.33 g/kg) contents that is caused by burnt earth residue from the burning of secondary forest. Sri Aman (12 months old) showed greater TOC (3.34%), P (0.0032 g/kg), and K (0.10 g/kg) benefitted from a long year of cultivation and proper pre-establishment earlier. Nutrient removal is high in Bintulu for Fe, Mn, N, and K, while Sri Aman for P is due to early harvesting before its mature phase, whereby the increase in nutrient accumulation in leaves to support berries. Correlation has revealed the role of soil pH in governing the availability of TOC, P, and K. The increasing soil pH increases the availability of P and K.  Hence, the availability of N, P, and K is affected by numerous reasons, such as pH and crop management.

Abstract

This research aimed to induce in vitro and identify polyploidy plantlets of Porang (Amorphophallus muelleri Blume) after colchicine treatment. In vitro shoot base explants of porang were cultured on MS medium containing different colchicine concentrations of 30, 60, 90, and 120 mg/l for four weeks while the control was medium without colchicine. After four weeks, all treated and untreated explants were multiplied and regenerated into plantlets. Flow cytometry and chromosome count were employed to determine the plantlet’s ploidy level and chromosome number, respectively. The result showed that colchicine inhibited explant growth, shoot formation, and plantlet regeneration. Increasing colchicine concentration reduces the capacity of explant in shoot formation, the number of shoots and plantlet regeneration. Of 19 plantlets regenerated from colchicine-treated explants, nine plantlets were mixoploid. Percentage of mixoploid plantlet regenerated from treated explant with 30 mg/l colchicine was higher than 60 mg/l colchicine. Mixoploid plants are mixed diploid, tetraploid, and octoploid cells. Chromosome count confirmed that the diploid cell of A. muelleri has 26 chromosomes and a colchicine-induced triploid and tetraploid cell has 39 and 54 chromosomes, respectively.

Abstract

The current method to break oil palm seed dormancy is the dry heat method which requires approximately 90 days for seeds to germinate with an average germination percentage. Therefore, hastening the process with a higher ratio of germinated seeds becomes necessary. This experiment aims to hasten and increase germination percentage by applying fine bubble water during the dormancy-breaking process. A seed lot derived from one bunch as replication is divided into two sets where fiber plugs from one of the sets are removed while the other set remains intact. Each set was re-divided into six experimental units soaked with tap water or fine bubble water for 1 to 3 days. The result showed that applying fine bubble water provided a better germination rate than tap water treatments. However, the total germination percentage between all treatments does not differ significantly. The germination peak of oil palm seed in the fine bubble water treatments occurred on the 26th day, 8 days faster than in the tap water treatments. The occurrence showed the potential use of fine bubble water application during dormancy breaking using the dry heat method.

Abstract

The work studies the effect of microbiological preparations based on the culture of B. subtilis and B. megaterium on the growth processes, photosynthetic parameters, and grain productivity of oats. Field tests were conducted in 2019 in the conditions of a micro plot experiment in the North-West of Russia. Microbiological preparations were introduced by soaking seeds and treating plants in the third leaf stage with preparations of 1 ml/l.The research finds that the introduction of microbiological preparations leads to a significant increase in growth. In the tillering stage, the leaf surface area of the experimental plants was higher by up to 40.1%, and plants' fresh and dry mass increased by 27.8–58.9%. Introducing microbiological preparations increased the average daily increments and the net productivity of plant photosynthesis by 1.080–2.801 g/m2. By the time of harvesting, the mass of the experimental plants remained higher by 13.4–23.3%. The studied preparations increased the grain productivity of oats by up to 16.3% compared to the control. The study indicated a positive effect of microbiological preparations based on B. subtilis and B. megaterium strains on oats.

Abstract

Spodoptera litura Fabricius pest control using botanical pesticide from papaya leaves extract (PLE) is an alternative to substitute chemical pesticides. The study aimed to determine the levels of PLE's activity and evaluate the effectiveness of PLE from different altitudes (low and middle lands) and cultivars (Thailand and Indonesian) against the attack of S. litura Fabricius larvae. An experimental study with a randomized block design (n=5) was conducted from December 2020 until April 2021. Each replication used 100 soybean plants and sprayed with 0% or 20% PLE of Indonesian purple cultivar low land (UR-20%), Indonesian purple cultivar middle land (US-20%), Thailand cultivar low land (TR-20%), and Thailand cultivar middle land (TS-20%), respectively and observed at 72 hours after treatment. The results demonstrate that the middle lands contained active compounds slightly higher than the lowlands. The damaged soybean leaves and intensity of soybean leaf damage are highest in control (77% and 63%) and significantly different from the treatment group, 53-60% and 29-41%, respectively. The mortality of S. litura Fabricius larvae in the control group was 11%, and in the treatment group, 47-63%. PLE from different altitudes and cultivars reduce the intensity of soybean leaf damage by S. litura Fabricius larvae.

Abstract

The rice crop intensification led to soil degradation and yield decline in the Mekong Delta, Vietnam. Therefore, it is necessary to classify soil fertility and identify the constraints for proper soil use. The soil legend classified by World Reference Based was converted to the Fertility Capability Classification system. The soil constraints and recommendations for appropriate services are suggested. The findings indicate seven primary soil categories, ten diagnostic layers, three diagnostic features, and three diagnostic materials in the rice soils of the Mekong Delta. Eleven soil constraints were found, most of which were associated with acid sulfate and saline soils. These constraints included low acidity, strong acidity, low available P, high P fixation, high potential Fe toxicity, slightly actual acid sulfate and shallow potential acid sulfate, deep potential acid sulfate, slight salinity, and strong salinity, low mineral supply capacity, limited organic carbon content, and low nutrient retention capacity. Reclamation of acid sulfate and saline soils by leaching soil toxicity and boosting soil nutritional status with organic matter and P, K treatment were recommended for degraded, acid sulfate, and saline soils.

Abstract

The tassels of corn can be utilized as a co-product for the production of phytochemicals. The objectives were to assess the impact of pigmentation and genotype on the levels of anthocyanins, phenolic compounds and antioxidant activity, and to determine the phenotypic stability of these traits. Sixteen genotypes were evaluated at two locations over two seasons. Corn genotypes in purple or pink pigmentation group had higher anthocyanin concentration and DPPH radical scavenging activity in tassel than those in normal green group. Tassel color can be used as a selection criterion to improve anthocyanin and antioxidant activity, but the trait is not effective to predict the phenolic concentration in the tassel. Genotype is an important source of variation for all parameters. The sensitivity of corn genotypes with high levels of measured compounds to the environment indicates the importance of choosing suitable locations and seasons for the production of high-quality corn tassels as a co-product of grain and vegetable corn. The findings of this study can be valuable for producers who intend to select genotypes for phytochemical production in corn tassels, as well as to corn breeders who aim to develop improved varieties with high yield and high bioactive phytochemicals in tassel.

Abstract

One of familiar green soybean, edamame is a vegetable that popularly chosen by the richest consumer. The reducing inorganic fertilizers can be realized gradually by transforming the farming from conventional to organic. Related to transformation, we observed the suitable combination of inorganic and organic fertilizers for the edamame growth and production. By a randomized block design, seven combinations of inorganic fertilizers (150 kg/ha Urea, 150 kg/ha SP-36, 100 kg/ha KCl) and organic fertilizers (compost) were applied. Three repeatations was adopted for each treatment and 30 plants per plot was used. The analysis of variance and Tukey HSD at 5% error were chosen. Based on the result, the combination of inorganic fertilizers and compost effect four plant growth and development variables such as the plant height, the number of leaves, the number of productive branches, and the time to produce 50% of a flower. The application of inorganic fertilizers at 50% and 75% combined with compost 10 t/ha increased the plant height, the number of productive branches, and the number of leaves. The number of seeded pods and the pod weight are not affected by all combinations of treatments.

Abstract

Wilt disease caused by Fusarium oxysporum is one of the most serious plant diseases in the world. There is no effective contol for. This study investigated the potential of arbuscular mycorrhizal and bacterial antagonists to control F. oxysporum through in vitro and in vivo studies. In this study, the antagonistic bacteria Stenotrophomonas maltophilia was isolated from mycorrhizal propagation media. Antagonist bacteria S. maltophilia showed antagonistic ability against F. oxysporum with an inhibition zone of 17.9 cm. Antagonistic bacteria and mycorrhizae used in this study significantly reduced the incidence of fusarium wilt in in vivo experiments. It was found that mycorrhizal and S. maltophilia inoculation showed disease incidence rates at 40% and 47.6%. While in the control treatment the incidence of disease reached 90.3%. The biocontrol agents of S. maltophilia and mycorrhizae have a promising prospective strategy to protect garlic plants. These results are expected to provide new insights for sustainable crop protection systems.

Abstract

There are three microbes that originated from the roots (Rhizosphere) of the cocoa plant (Theobroma cacao L.) as a potential biofertilizer. This research aimed to specify the ability of microbial isolates in a consortium with the addition of Biosurfactant Diethanolamide. The three microbes were observed using synergism test, molecular and population identification in the consortium. The synergism test showed the three isolates were not mutually antagonistic indicated there was no clear zone around the colony. The molecular identification showed the isolate 1 was as Bacillus substilis (99.88% hegemony), isolate 2 was as Bacillus substilis (99.75% hegemony) and isolate 3 was as Bacillus amyloliquefaciens (100% hegemony). The population consisted of  3.6 x 106 cfu/ml Azotobacter, 0.55 x 101 cfu/ml Azospirillium and 2.5 x 105 cfu/ml phosphate solubilizing bacteria. The results of the calculations on the microbial consortium with the addition of Biosurfactant Diethanolamide were 3.75 x 106 cfu/ml Azotobacter, 0.1 x 102 cfu/ml Azospirillium and 1.65 x 105 cfu/ml phosphate solubilizing bacteria.
