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.

Abstract

A bulbil, as planting material, is difficult to stimulate to grow in a dormant state. This study examines the hydropriming effect on shoot emergence and the shading treatments on leaf and cormel growth during the vegetative stage. The priming was carried out by soaking the bulbils in distilled water for 0, 3, 6, 12, and 24 hours and the shading treatments at 0, 40, and 80 percent. The results show that the imbibition occurred immediately during the first 3 hours and continued to increase up to 24 hours. The bulbil re-drying process reached the pre-treatment water content in less than three days. Significantly the earlier emergence was observed in the plants exposed to the 80% shading. The petiole sheath breakup was not affected by the hydropriming and shading. The konjac planted in the shading treatment produced more sprouts, longer but slender petioles, larger but thinner leaves, and larger cormel size. The differences in fresh and dry weight were more related to tuber moisture content than the direct effect of the shading treatment. The SPAD value of konjac leaves immediately increased within a few days after the application of the NPK fertilizer and consistently lasted for four weeks.

Abstract

Superior upland rice varieties can be obtained through the plant breeding process. Upland rice lines that are carried out from crossing have different potentials. The research aims to determine upland rice promising lines with high yields in acid-dry land. The study is conducted on Ultisol soil. The first season is in 2019 for F6 lines, and the second is in 2021 for F7 lines. The experimental methods use factorial Randomized Block Design (RBD). The treatment at the preliminary yield test use 5 lines 4 varieties, and 1 landrace. The advanced yield test uses 5 F7 lines (selected from F6 lines) and 5 types. Analysis data use ANOVA and LSI test. The result shows that lines GH8 and GH10 have the highest yields on acid-dry soils during two planting seasons. The GH10 line has a 7.20-9.53 kg/plot yield, and the GH8 line has a 5.22-6.26 kg/plot. The highest yield potential was the GH10 line of 3.69-4.77 t/ha, more increased than Balok, Banyuasin, Danau Gaung, Inpago 8, and PBM-UBB1 varieties. GH10 and GH8 lines are recommended as candidates for new superior varieties of upland rice that are adaptive to acid-dry soils.

Abstract

Red clover (Trifolium pratense L.) is a perennial plant of the legume family (Fabaceae). It is grown both in pure culture and in crops with perennial grasses. This study aims to assess the yield of red clover for hay (two cuttings) and pasture (four slopes) use in the soil and climatic conditions of the Western region of Ukraine. The subject of the study is four breeding numbers created by hybridization and selection methods. The placement of variants is systematic in a sequential arrangement of repetitions in several tiers. Field experiments were carried out over three years (2018–2020) in competitive variety testing. The study found that, on average, the period from regrowth to slope ripeness lasted 67–95 days, from regrowth to pasture ripeness (30–61 days), and from regrowth to economic ripeness of seeds (136–172 days), depending on the years of cultivation. With the hay use of red clover, the yield is 41.14–44.78 t/ha, with the pasture 50.18–52.38 t/ha.

Abstract

The objective of this study was to obtain a seed-origin onion (Allium cepa L.) that was able to grow in the tropical riparian soil. Research designed with non-experimental. Two cultivars were studied, namely Sanren and Lokananta. Onion seeds were planted directly without transplanting, there were three plots (4 m x 1.6 m x 0.3 m) and three germination testplot (1 m x 1.6 m x 0.3 m). Soil tillage, spacing/ population, fertilization, plant maintenance and pest-diseases control in accordance with the recommendations. Research result obtained Sanren had higher germination (94.40%) and vigor index (60.60) then Lokananta. The growth of two onion cultivars showed good performance because there was no transplanting. Almost all the the variables for seedlings, vegetative organs and bulbs were significantly different between two cultivars. From the boxplot test, it was found that the data were of symmetry for Sanren (number stems, dry weight of leaves, and dry weight of bulb), and the Lokananta cultivar (vigor index, number of stems, number of bulbs, plant height and leaf dry weight). There was a significant correlation for Sanren (plant height with bulbs weight and number of roots), and Lokananta cultivars (number of roots with number of stems and leaf dry weight). Fresh bulbs weight per clump from Sanren (46.71 g) and Lokananta (17.84 g).

Abstract

Field and laboratory investigations of tobacco plants were carried out to analyze the distribution of Verticillium wilt caused by V. dahliae. V. dahliae is isolated from field Z (Tarkhai, Yarhussain region of Swabi). Species of Fusarium and Actinomycetes were detected in field B (Shaheedan, Yarhussain region of Swabi), while no V. dahliae was isolated from these fields. V. dahliae was identified based on its colony and conidia morphology. The colony was white, having oval spores and septate mycelium with phialides. The isolate also produced irregularly elongated dark brown to black color microsclerotia of various sizes. The spores count for V. dahliae isolate was 3.61 × 108 conidia/ml. The average colony diameter of V. dahliae after 9 days of incubation on PDA and CM media was 6.55 cm and 5.5 cm, respectively. The biology of Verticillium spp. in tobacco plants and soil in Swabi has not been studied. For the first time, this study reported the presence of V. dahliae in the tobacco fields of Swabi, KPK Pakistan. Detection and isolation of V. dahliae from field soil are necessary for studying the ecology and virulence and creating deterrent control strategies for Verticillium wilt diseases.
