Abstract

This study aims to determine the response’s incompatibility of selected dwarf citrus rootstock after treated by abiotic stresses such as drought, waterlogging, and acidity on a scion. The results of this study was selected seedlings for sub-optimal lands in Indonesia with dwarf growth characteristic and compatible with the grafted-scion. The preliminary study has shown that there were 3 (three) selected rootstock accessions with dwarf characteristics, namely Citromello (Cit), Volkameriana (Volk), and Cleopatra Mandarin (CM). The seeds of these accessions were treated with 8% Polyethylene Glycol (PEG), 150% FC; 9 mM Al2SO4 at eight months after planting. Each rootstock was grafted with Pontianak orange (C. nobilis var. microcarpa). The results showed that Citromello (Cit) and Volkameriana (Volk) are incompatible rootstock and dwarf potential seedling. However, Cleopatra Mandarin has a compatibility with the grafted scion and is tolerant of abiotic stress treatments. The effect of abiotic treatment on Citromello resulted in 15% higher root length higher than other accessions. Furthermore, this variety has 40% dry weight and 25% lateral root numbers, respectively, by Al2SO4 and PEG. Meanwhile, Volkameriana had the 40% higher number of leaves.

Abstract

Virus infection in chili plants may cause various symptoms. The complexity of the symptoms and human vision ability often become limiting factors during disease investigations. Digital image analysis is expected to become a method to assist in comprehensively describing the symptoms of plant viruses. A disease survey was conducted on cayenne pepper fields in Southeast Sulawesi Province to observe symptoms of virus infection virtually and to record the symptomatic plant using an RGB camera. The split-channel method is used to process images, followed by multidimensional scaling statistical analysis. Later on, viruses associated with plants were detected serologically. Single or mixed infection of Tobacco mosaic virus, Cucumber mosaic virus, Chili veinal mottle virus, and Pepper mottle virus was confirmed by plant leaves showing yellow-mosaic and mottle symptoms. The digital image analysis method could show variations in the characteristics of symptoms based on digital numbers in that cannot be recognized based on the observation of visual symptoms. A new approach to study the interactions between plant infecting viruses and their effects based on image analysis has also been developed during this research. This method needs to be further validated through testing under controlled conditions, such as inoculating plants with a predetermined type of virus.

Abstract

Pleurotus species are the common mushrooms popularly cultivated in the Philippines while Fermented Plant Juice (FPJ) is a known organic concoction which can help crops to grow. This study aimed to find out the effects of FPJ on the mycelial growth, basidiocarp production and sensory attributes of different species of Pleurotus in culture media, grain spawn and fruiting substrates supplemented with varying amounts of FPJ. The experiment was laid out in complete randomized design and replicated thrice for culture media and grain spawn; and replicated ten times for the fruiting substrates. P. florida in 20 ml culture media supplemented with 2.4 ml of the 120 ml FPJ solution had the fastest mycelial growth while P. citronipleatus in grain spawn supplemented with water had the fastest mycelial growth. P. ostreatus grown in 750 g dry weight of fruiting substrates supplemented with 150 ml of FPJ had 6.83 higher yield than the control, thus higher profitability and Return on Investment (ROI). Significant differences were also observed on the sensory attributes such as taste, aroma and general acceptability. Majority of the respondents liked P. florida which is considered as very much palatable. As the concentration of FPJ become higher, the taste becomes better.

Abstract

The availability of seeds is one of the most essential aspects of agricultural development in developing countries and Indonesia is no exception. This requires adequate technological innovation and institutional support. This study aims to describe the synergy of innovation at the level of national companies that provide hybrid corn seeds to farmers. Three levels of company performance were compared namely well-established companies, middling, and less-developed companies. The results showed the performance of hybrid corn seed companies from 2019 to mid-2022 was mainly influenced by the degree of synergy between seed companies and their supporting institutions in implementing improvements in seed production technology. Established companies have better synergy with supporting institutions, hence, they can adequately apply seed production technology producing 4,900 tons of quality seeds, and distributing them to various regions specifically 12 provinces. Meanwhiles, companies that have low synergies with their supporting institutions are very weak, producing seeds only in small quantities at 400 tons. This implies that technological innovations and institution synergy for hybrid corn seed production can be applied by national companies with adequate support from local institutions.

Abstract

One aim of productivity improvement on red beet was to restrain over-reducing the betacyanin as a secondary metabolite.  Different nitrogen (N) sources were projected to affect growth, yield, and both primary and secondary plant metabolites.  The research was carried out to find the effect of different sources and dosages of N on the production improvement and betacyanin.  The N sources consisted of 5Ca(NO3)2NH4NO310H2O, NH4NO3NH4H2P04KCI, NO3H2P04KCI, CO(NH2)2, and (NH4)2SO4 with the N dosages of 75, 150, 225 kg N/ha and without N treatment as a control.  The results showed that the enhancement of N dosages increased higher beet root fresh weight (BRFW) for about 42-50% than control.  The 5Ca(NO3)2NH4NO310H2O and CO(NH2)2 increased BRFW and were higher than other N sources.  The said N sources also contributed to 36% and 25% higher total betacyanin (BT) than those of (NH4)2SO4 and control, respectively.  BRFW had the similar with BT, yet opposite patterns with betacyanin content (BC). The increase N dosages from any source diminish 20-33% BC, which was correlated with the increase of BRFW and BT following the sigmoidal pattern based on the logistics model during the growing period.

Abstract

Amorphophallus oncophyllus Prain ex Hook. f. synonym A. muelleri Blume is the main source of glucomannan that is used as a food additive and dietary supplement. The crop has become a favorite in several parts of Indonesia. The plant has been known to have several pests and diseases that can cause significant losses. This review aims to highlight the importance of pests and diseases of konjac and its control strategy. Several pests and diseases attacking the konjac plant have been identified, such as mealybug, scale insect, dry and soft root, collar rot, bacterial blight, leaf spot, and mosaic. The majority of them are seeds or soil born and could be carried from the field to storage. Understanding the causal agents and their ecology is critical in formulating integrated pest management (IPM). Cultivating healthy seeds and mixed cropping with nonhost food crops (maize and rice), or as a second crop under estates’ and industrial forests’ conditions, as well as biological control, are the most applicable IPM. No specific regulation has been formulated for minimizing pests and diseases of konjac; however, it could adopt general protocol from other crops, such as taro (Colocasia esculenta) in India.

Abstract

Biochar quality is influenced by the type of its raw material and pyrolysis temperature. Nevertheless, the quality criteria of biochar as a nutrient carrier remain unanswered. This study aimed to find the chemical properties, micromorphology, and optimum pyrolysis temperature from various agricultural wastes to obtain good biochar as a nutrient carrier. This experiment was conducted at three level temperatures: 400, 500, and 600°C, and the raw materials were coconut shells, oil palm shells, and corn stalks. The chemical and physical properties of biochar were: pH-H2O, OC, CEC, total N, P, K, Mg, Ca, and Na, ash, functional groups, amorphous carbon, morphology, and SSA. The results show that the coconut shells and oil palm shells biochars contained high levels of N-total and the chain-C aromatic, and the pore structure was solid and regular. Corn stalks biochar containing ash is high, and C-aromatic is low and fragile. Increased temperature of pyrolysis produced well-crystallized minerals. It is concluded that 500°C is the optimum temperature for oil palm shells pyrolysis resulting in biochar with the highest C-aromatic structure and arrangement of pores which are strong, regular and uniform, and high stability, but the nutrient content was low.

Abstract

There has been a tendency of decreasing sugarcane productivity (Saccharum officinarum Linn) in Indonesia due to poor soil available potassium. There has also been evidence that available soil potassium relates directly to soil condition. For this reason, the management of sugarcane engaging Site Specific Nutrient Management (SSNM) must be pursued. The first and most important stage in SSNM is assessing variability, which can be used to recommend particular fertilizer. This research’s main aim is to assess the variability of Potassium and Brix content for uses in the Potassium (K) fertilizer recommendation. The methodology used in this research is collecting data in the field, analyzing with Geographical Information Systems (GIS) using Kriging techniques, and developing a site-specific K prescription map. The results show that (1) spatial analysis assisted in developing a prescription map for K management in sugarcane; (2) spatially, the area can be classified into three classes (low, medium, and high) of K with the recommendation of 300 kg/ha (low), 200 kg/ha (medium) and 0 kg/ha (high) respectively. The results suggest that spatial analysis of soil available potassium and Brix content can provide a whole and specific picture of the area studied, which is beneficial for SSNM.

Abstract

Studies of the effects of landscape composition on pests and their natural enemies on agroforestry systems is still limited, whereas the system can maintain biodiversity. This research investigated the impact of agricultural landscape composition on shaping the interaction between pests and natural enemies in cacao agroforestry. The study was conducted in twelve cacao plantations spread across five districts in East Java, Indonesia. A sampling of insects was carried out by observing the intensity of pest attacks and the diversity and abundance of predators. The surrounding landscape of the cacao field was characterized by manually digitalizing the land use. The results found two main pests attacking all cacao plantations: cacao pod borer, Conophomorpha cramerella (CPB) with attack intensity 0.72-12.05%, and Helopeltis sp. with attack intensity 12.39-42.24%. Management of cacao plantations, such as intensification and canopy cover, significantly affected the attack intensity of CPB but not Helopeltis sp. Based on the generalized linear model, the landscape composition, especially the patch number of natural habitats, positively impacted CPB attack intensity and predator abundance. However, predator abundance harmed CPB attack intensity. In conclusion, the proportion of natural habitat in agricultural landscapes contributes to reducing the attack intensity of pests via maintaining natural enemy abundance.
