The implementation of agronomic activities, based on the use of biostimulants, is an important element of agroecological practices. Therefore, a comprehensive field trial was carried out to evaluate the potential of biostimulants in growth promotion across four districts of Maharashtra (Jalna, Ahmednagar, Aurangabad and Nasik). The study aimed to evaluate the candidacy of selected biostimulants in improving onion (Allium cepa L.) extracted from proprietary technology involving adaptive molecular re-engineering for plant growth biostimulants category. Three biostimulants were preliminary analyzed for their nutritional content. Compositional analysis revealed the presence of several macro, micronutrients as well as humic, fulvic acid. The concentration of humic and fulvic acid in sediment extract were ranged from 34-38 and 10.5-10.8 g/100g respectively. The organic carbon, total nitrogen, phosphorus, and ash contents ranged between 54-57,0.4-0.6, 0.3-0.4, and 3.3-7.2% respectively. Ash and total nitrogen content were the same for the extract 0.2% and 7.8% respectively. Onion crops were treated in three different modes, seed treatment, root drenching and foliar spray. Biostimulants were applied in combination with three different levels of chemical fertilizer 50%, 75%, and 100% RDF and compared with Control (100%RDF without biostimulants). Several qualitative and quantitative parameters such as firmness, pungency, neck diameter, bulb diameter, and yield were analysed. It was observed that all three biostimulants (Asaava, Somrith, and Yuvaani) significantly(P<0.001) affected all the measured plant traits. In addition to this, overall, we found excess chemical fertilizer imposed adverse effect on plant growth parameters. Moreover, it was concluded that with seed treatment followed by root drenching and foliar spray and optimized dosage scheduling, yield can be further improved. The best effect in overall growth and yield potential of the plants were noticed in Asaava treated plants.

The most exquisite flowers and long-lasting qualities of ORCHIDS make them among God's creations regarded as the most beautiful in the entire world. They are perennial herbs that are members of the Orchidaceae family. In addition to hybrids regularly created, there are reported to be nearly 25000 orchid species spread across 730 genera. Epiphytes include orchids, which are plants that grow on trees. Terrestrial refers to those that grow on the ground. Lithophytes are those that grow on rocks, while saprophytes are some relatively unknown ones that grow on decomposing matter or rotting logs. A few orchid species can grow partially submerged in water, with only the inflorescence occasionally reaching the surface.

An experiment on the growth and yield responses of cassava (Manihot esculenta Crantz) using two compound fertilizer types was conducted at the Teaching and Research Farm, Rivers State University Port Harcourt between March 2021 and February 2022. The treatments consisting of three cassava varieties (TME 419, TMS 95/0289, TMS 96/0523) and two compound fertilizer types (NPK 20-10-10, NPK 15-15-15) and a control without fertilizer application were combined in a split plot arrangement with cassava varieties to the main plot while fertilizer types took the subplots, in a Randomized Complete Block Design (RCBD) replicated three times. Parameters evaluated were plant height and leaf number at four weekly interval starting at ten weeks after planting, also tuber number and tuber weight. Results show that cassava variety TME 419 interacting with NPK 15-15-15 produced the highest plant height (288.3cm) while TMS96/0523 without fertilizer application produced the lowest plant height(199cm) at harvest. Cassava variety TMS 95/0289 interacting with NPK 15-15-15 produced the highest tuber number per plot (241.3) and per stand (10.1) respectively. Cassava variety TMS 96/0523 interacting with NPK 15-15-15 produced the highest leaf number per stand (103.3). Application of NPK fertilizer especially NPK 15-15-15 enhances tuber number, leaf number and plant height. Cassava variety TMS 95/0289 produced the highest tuber number and tuber weight. Thus it is recommended that TMS 95/0289 be recommended to farmers as it produced highest tuber number and tuber weight. Also, fertilizer NPK 15-15-15 is a preferred NPK fertilizer as it produced high yield in tuber number per stand and tuber weight.

Background and Objectives: Farmers currently employ nationally approved fertilizer rates and plant spacing when growing onions, but knowledge of plant population density and fertilizer rates that may produce the best bulb production for different cultivars and locations is limited. As a result, gardeners frequently use nonspecific plant population densities for various cultivars, resulting in sub-optimal bulb yields. Materials and Methods: A field experiment was conducted in 2019 from August to December to study the effects of intra-row plant spacing and levels of nitrogen on yield and quality of onion (Allium cepa L.) variety Nafis under irrigation. Results: The main effect of intra-row spacing on stand count and both nitrogen levels and intra-row spacing on plant height and the number of leaves per plant was observed. The interaction of nitrogen level and intra-row distance affected days to maturity, leaf length, leaf diameter, bulb diameter, mean bulb weight, marketable and unmarketable bulb yield, and all bulb size categories. Increased intra-row spacing to 10.5 cm and N rate of 82 kg ha-1 increased marketable and total bulb yield by approximately 3.14 and 3.21 t ha-1, respectively, spacing and decreased unmarketable bulb yield by 1.38 t ha-1. Conclusion: The use of 82 kg ha-1 N at the intra-row spacing of 10.5 cm was optimum for bulb production of onions. 82 kg ha-1 N at 10.5 cm intra-row spacing resulted in the highest net benefit.
背景和目的:农民目前在种植洋葱时使用国家批准的肥料用量和种植间距，但对不同品种和地点的植物种群密度和肥料用量可能产生最佳鳞茎产量的知识有限。因此，园丁经常对不同品种使用非特定的植物种群密度，导致球茎产量次优。材料与方法:于2019年8 - 12月进行了大田试验，研究了灌溉条件下行间距和施氮水平对洋葱(Allium cepa L.)产量和品质的影响。结果:行距对林分数的主要影响是氮素水平和行距对株高和单株叶数的影响。氮素水平和行内距离的互作影响了催熟天数、叶片长度、叶片直径、鳞茎直径、平均鳞茎重、可售和滞销鳞茎产量以及所有鳞茎大小类别。增加行距至10.5 cm和施氮量为82 kg hm -1，可使滞销鳞茎产量分别增加约3.14和3.21 t hm -1，但可使滞销鳞茎产量减少1.38 t hm -1。结论:行间距10.5 cm施用82 kg hm -1氮肥最适宜洋葱鳞茎生产。行间距为10.5 cm，施氮量为82 kg hm -1，净效益最高。

Increased intra-row spacing to 10.5 cm and N rate of 82 kg ha-1 increased marketable and total bulb yield by approximately 3.14 and 3.21 t ha-1, respectively, spacing and decreased unmarketable bulb yield by 1.38 t ha-1. \u0000Conclusion: The use of 82 kg ha-1 N at the intra-row spacing of 10.5 cm was optimum for bulb production of onions. 82 kg ha-1 N at 10.5 cm intra-row spacing resulted in the highest net benefit.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117296182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: Mealybugs are protected on plants by ants for honeydew. They were identified and assemblages were characterized in Douala suburbs (Littoral-Cameroon). Study Design: Basic information is needed on pest’s occurrence for the pest control strategies. We determined host plants and characterized the community structure of mealybugs and foraging ants. Place and Duration of Study: Field investigations were conducted from March to August 2020 in Douala suburbs in 16 transects (10x1,260 m each) and 126 quadrats (10x10m each). Methodology: Stems, the underside of leaves, flower buds and fruits were inspected on weeds, plant bases and canopy of trees. Mealybugs and ants were captured. When the plant was highly infested, the average number of insects was determined on 10 randomly chosen plant organs. Abundances were noted and captured specimens were stored in vials containing 70° alcohol, identified to the species level and the community structure was characterized. Results: A total of 24,640 specimens belonged to 23 families, 54 genera and 85 species were collected in this research. A low species richness, low diversity and low dominance were detected. Assemblage of foraging ants in Yassa functioned according to the brokend-stick model. Scale insects in Ngoma functioned according to Motomura’s model. Assemblages of host plants in Lendi, Yassa, global host plants, global scale insects, foraging ants in Lendi and the global settlement, functioned according to the lognormal model. Host plants in Ngoma, scale insects in Yassa, and foraging ants in Ngoma functioned according to Zipf’s model while Zipf-Mandelbrot was adapted to scale insects in Lendi suggesting that these communities had sufficient time to develop a complex network of information close to natural environments and presented a fairly regeneration force. Conclusion: Due to the abundance pest insects, resources are available and once they will be well developed; they will cause plant pathologies and yield loss.

A field experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during November, 2020 to February, 2021. The experiment was laid out in a Randomized Complete Block Design with three replications. The experiment had two factors (Different levels of salicylic acid, S0= No salicylic acid (control), S1= 60 ppm of salicylic acid, S2= 90 ppm of salicylic acid and different levels of zinc, Z0= No zinc sulphate (control), Z1= 25 ppm of zinc sulphate, Z2= 50 ppm of zinc sulphate. Different levels of salicylic, zinc sulphate and also their combinations showed significant influence on different growth, yield contributing parameters and yield of squash. The treatment, S2 showed highest results in fruit yield per plant (2422.7 g), fruit yield per plot (9.68 kg) and fruit yield per ha (37.83 t) compared to control. In case of zinc treatments, the highest results in fruit yield per plant (2597.1 g), highest fruit yield per plot (10.38 kg) and highest fruit yield per ha (31.74 t) were found from Z1 compared to control. Likewise, the treatment combination of S2Z1 (90 ppm of salicylic acid and 25 ppm of zinc sulphate) gave the highest fruit yield per plant (3045.4 g) fruit yield per plot (12.18 kg) and highest yield per ha (47.57 t) where the lowest results were found from the treatment combination of S0Z0 (control). The highest gross return (BDT 1189425), net return (BDT 881669) and BCR (3.86) were obtained from the treatment combination of S2Z1 where the lowest was obtained from S0Z0. It can be concluded that from economic point of view, S2Z1 (90 ppm of salicylic acid and 25 ppm of zinc sulphate) treatment combination is suitable for squash cultivation than other treatment combinations.

An experiment was carried out to ascertain the effect of light regimes (continuous day light, continuous darkness and alternating day light and darkness) on the growth of A. flavus on tiger nut at temperature of 28oC and 30oC. The experiment was a 2 x 3 factorial laid out in a completely randomized design (CRD) replicated 10 times. A. flavus was isolated from naturally infected tiger nuts obtained from different sellers at Delta Park, Abuja Park and Choba campus, University of Port Harcourt, Rivers State, Nigeria. The isolation and sub-culturing were done using Malt Extract Agar (MEA). A tiger nut-based-medium (15ml/Plate) was centrally inoculated with 6-day-old inoculums of A. flavus and incubated appropriately. Assessment of fungal growth was done daily for 10 days and mycelia diameter and mycelia growth rate obtained from the data. Result from the statistical analysis showed that the effect of light regime and temperature on the mycelia diameter of A. flavus was highly significant (P<0.001) and the interaction between light regime and temperature was also significant (P<0.0.01). Growth rate also showed significant (P<0.001) main effect of temperature and light regime and the light regimes x temperature was also significant (P=0.03). The highest mycelia growth rate and mycelia diameter occurred in continuous day light, followed by continuous darkness and finally alternating day light and darkness, with all higher at 30oC. Thus, storage of tiger nut under continuous day light and/or at temperature 28oC and above should be discouraged, in order to reduce microbial spoilage caused by Aspergillus flavus.
