Abstract

Molecular techniques have been applied as fast and accurate detection methods of plant pathogenic bacteria. Bacteria-specific primer 27F paired with the universal primer 1492R was used in PCR to detect plant pathogenic bacteria in symptomatic leaves of tomato (Solanum lycopersicum L.), chili pepper (Capsicum annum L.), napa cabbage (Brassica rapa subsp. pekinensis L.), cabbage (Brassica oleracea var. capitata L.), and longan (Dimocarpus longan Lour.). The targeted single bands with length of 1400 bp were obtained but bidirectional sequencing of the PCR products recovered partial sequence of chloroplast instead of bacterial genomes. Thus, this result confirmed cross amplification of 27F/1492R primer pair against chloroplast genome of plants. Phylogenetic tree was constructed to separate the tested isolates according to their taxonomic relations: Order Sapindales, Solanales, and Brassicales. In-silico analysis on the new five and nineteen selected sequences in NCBI GenBank detected at least seven conserved regions with some single nucleotide polymorphisms. This report might be a cautionary advice for other researchers to avoid false positive results which could lead to misdiagnosis of bacterial plant diseases.

Abstract

Rice contributes a significant function in reducing food insecurity in sub-Saharan Africa including Nigeria. This study evaluates the nexus between farm size, fertilizer input, and technical efficiency (TE) of rice production, Nigeria. Data covered 200 rice farmers proportionally distributed in Kano and Kaduna states. The TE levels were obtained using parametric approach such as stochastic production efficiency frontier model (SPEFM) and descriptive statistics. The production constraints of rice farmers were evaluated using PCA (Principal Component Analysis). The average TE score of rice producers is 53.13% leaving an efficiency gap of 46.87% for improvement. Inferential analysis showed that the significant predictors influencing TE of rice production include fertilizer, farm size, agrochemicals, seed, and family labour. The addition of the first-order of the production predictors which is called the scale elasticity shows increasing RTS (return to scale) which is estimated at 1.958. The sources of TIE (technical inefficiency) of rice production were age, experience in rice farming, education level, members of cooperatives, and amount of credit accessed. The coefficient of variance ratio, the gamma is 0.7827, this connotes that 78.27% of variations in the output of rice were due to differences in TE. The major production constraints facing rice producers include lack of access to farm land (1st), high cost of fertilizers (2nd), and lack of agrochemicals (3rd). The cost of fertilizers should be reduced and made affordable for increased rice productivity and efficiency, secondly, easy access to farm land is necessary in terms of policy formulations and implementations.

Abstract

According to the Food Security and Vulnerability Atlas (FSVA) standard, of the 309 villages in Karawang, 63 are classified as food insecure. This study aims to determine the land conversion factors that affect food security in Karawang and to identify the factors influencing food access at the farm level. Using quantitative methods, including multiple linear regression analysis and logistic regression, the results show that the variable “number of industries” has a significant impact on food security, while income per month and farming experience significantly affect food access at the farm level. Additionally, food security (represented by the percentage of the poor) and regional security (represented by the crime rate) demonstrate a linear correlation.

Abstract

The fulfillment of rattan needs in the future will continue to increase, and it is estimated that rattan sources from natural forests will not be able to provide sufficient quantities. Therefore, rattan development is still needed, especially in cultivating it on community land or in community nurseries. Rattan cultivation needs to be developed by procuring good and quality rattan seedlings, one form of effort in increasing the productivity of rattan stems is through maintenance so that to obtain quality seedlings, additional materials are needed in the media to provide nutrients that support plant growth. One of the organic fertilizers that plays a role in soil quality and plant growth is cow manure compost where this fertilizer is processed animal waste or cow manure that is given to the soil to improve soil fertility. This study provides information on the effect of giving various doses of cow manure on the growth of rattan stem seedlings (Calamus zollingeri Becc) in polybags so that it can be used as a guide in utilizing the cow manure optimally. This study used a completely randomized design (CRD) consisting of five treatments, P0 = soil without cow manure (control), P1 = 1000g soil + 200g cow manure, P2 = 1000g soil + 300g cow manure, P3 = 1000g soil + 400g cow manure, P4 = 1000g soil + 500g cow manure, Each treatment was repeated 10 times so that it required as many as (5x10) = 50 experimental seed units.

Abstract

This study examines the impact of rice field conversion on the availability of rice in Jakarta Province from 1981 to 2023. Over this period, Jakarta experienced rapid urbanization, transforming agricultural land especially rice field area into urban infrastructure. The rice field area shrank from 7,720 hectares in 1981 to only 341 hectares in 2023, with rice production declining from 70,387 tons to 2,674 tons. Meanwhile, rice demand surged from 474 million kilograms in 1981 to 874 million kilograms in 2023 due to population growth. The study employs secondary data analysis, utilizing regression models to assess the influence of population density and productivity on rice field area. The results indicate that population density is the primary driver, with every unit increase leading to a loss of 104 hectares of rice field area. Conversely, productivity improvements had no significant impact on land size. The findings of current study highlight a growing dependency on external food sources, exposing Jakarta to food security risks. This research underscores the urgency of sustainable land management policies to balance urbanization and agricultural preservation. Recommendations include integrating land-use planning with food security strategies to ensure a stable and sufficient food supply for Jakarta's growing population.

Abstract

Red chili peppers (Capsicum annuum L.) is a type of vegetable that has economic value high and contains various compounds that are useful for human health. The aim is to determine the extent of the effect of Nitrogen and phosphore on the vegetative growth of red chili plants. This study used a two- factor factorial Randomized Block Design (RAK) method. The first factor is the dose of Nitrogen Fertilizer consisting of three levels, namely N1 (5 gr/plant), N2 (10 gr/plant), and N3 (15 gr/plant), the second factor is the dose of Phosphore fertilizer with two levels, namely P1 (10 gr/plant) and P2 (15 gr/plant). Observation variables include plant height, number of leaves, and number of branches. The results showed that there was a real interaction between nitrogen and phosphore fertilizers. Nitrogen Fertilizer treatment was significantly different from plant height, number of leaves and number of branches. The best Nitrogen Fertilizer treatment was at the N3 dose level (15 gr/plant). Furthermore, in the Phosphore fertilizer treatment, the best results were obtained at the P2 level (15 gr/plant) which affected plant height, number of leaves, and number of branches.

Abstract

This study aims to evaluate the response of K01 variety of Chinese cabbage (Brassica rapa) to different concentrations of AB fertilizer in a hydroponic system. The experiment was conducted for six weeks at the Horticulture Research Center, MARDI Serdang, Malaysia, using a Completely Randomized Design (CRD) with five AB fertilizer concentration treatments (T1 to T5), five replications, and six samples per replication. The tested AB fertilizer concentrations ranged from 0.8 to 2.0 EC. Parameters observed included leaf number, plant height, chlorophyll content, and leaf area index (LAI). The results showed that treatments with higher AB fertilizer concentrations (T2 and T3) produced the best results in leaf number, reaching 33.4 leaves by the sixth week. In contrast, treatments with lower AB fertilizer concentrations (T1 and T4) resulted in lower leaf numbers. This study concluded that optimal AB fertilizer concentrations can enhance leaf number and growth of K01 variety Chinese cabbage in a hydroponic system. Therefore, proper fertilizer concentration management is crucial in hydroponic cultivation of Chinese cabbage to achieve maximum growth.
