This research work was carried out to evaluate the immune response of 3 turkey strains to salmonella and Newcastle vaccines measured via antibody titre. The study deployed a total of 120 poults (40 black, 40 white and 40 lavender) strains. To ascertain the initial antibody titre of all the birds, blood samples were obtained from their wing veins immediately after acclimatization for salmonella and Newcastle antibody titre.  The test for salmonella and Newcastle antibody titre responses of the birds were performed using widal and haemagglutination inhibition (HI), respectively. The birds were divided into two broad groups tagged as A and B, which represented Salmonella and Newcastle vaccines, respectively. Each group had 3 sub-groups denoting the 3 strains of turkey used for the study. After vaccination, blood samples were collected from all the birds at 3 and 5 days for laboratory assessment of antibody titre response. The results showed that there was significant increase (p<0.05) in the antibody titre response of all the turkey strains after vaccination. Results obtained on the time of exposure of the birds to vaccine revealed that higher antibody titre values were obtained from the black and white turkey strains at 3 days than at 5 days after administration of Newcastle vaccine, except in the lavender strain, which had higher titre value at 5 days after Newcastle vaccination. Following administration of salmonella vaccine, black and lavender strains had statistically higher antibody titre response (2.03 and 2.10 mean loge widal, respectively) than white strain (1.86 mean loge widal). Similarly, the black strain also had higher antibody titre value when Newcastle vaccine was administered (2.35 mean loge HI) followed by lavender (1.99 mean loge HI) and white strain (1.71 mean loge HI). Black strains showed more antibody titre response and by implication, stronger immunity to Salmonella and Newcastle vaccines. More importantly, the differential response of the 3 turkey strains to vaccine could give turkey breeders the choice of selection of turkey breeds for disease resistance breeding.

Aims: The objective of this study was to determine the optimal fertilizing method and NPK fertilizer dosage for plant physiology and nutmeg yield.

Study Design: The experimental design was a completely randomized block design (CRBD) in a 4x3 factorial arrangement with three replicates. The first factor was four NPK fertilizer doses: 1, 1.5, 2.0, and 2.5kg NPK (15:15:15)/tree/year. The second factor was the manner of fertilizer application: (1) fertilized in spot, (2) fertilized in-furrow trenches trunked and (3) fertilized in hole.

Place and Duration of Study: The research was conducted in Tobelo North Halmahera (1°44'45.3"-1°44'54.4" N, 127°59'54.4"-127°59'53.2" E), North Maluku, Indonesia from January 2019 to May 2020.

Methodology: The nutmeg trees used was 30 years old. The population of trees plants in the study area was 40 trees. Observation parameters on leaves are chlorophyll a, b and total, nitrate reductase activity (NRA), N, P, K, proline content, number of young and old fruits.

Results: The fertilization treatment with the fertilizer application method into the crack/hole fertilizer with a dose of 2.5 kg NPK significantly produced high levels of chlorophyll a, chlorophyll b,         total chlorophyll of leaves and old fruit. The number of old fruits is positively correlated with chlorophyll a content (0.615*), chlorophyll b (0.663*), total chlorophyll (0.634*) and number of young fruits (0.748 **). The application of fertilizer hole produces plants that recover quickly from drought stress, as evidenced by the highest proline content.

Conclusion: NPK fertilization using the hole method and at doses of 2.0-2.5 kg/tree/year are recommended for improving plant physiology and yield.

DOI: 10.9734/arrb/2021/v36i330351

Aims: To identify the chemical components of five wild Botanical oils (BOs) and their larvicidal influences on the anti-nutritional indices of the 4th instar larvae of Agrotis ipsilon.

Study Design: A comparative study with the randomized design, using five plant Extracts replicated five times.

Place and Duration of Study: Mentha longifolia, Artemisia judaica, Majorana hortensis, Origanum syriacum, and Achillea santolina were collected from the Sinai desert, Egypt. Study procedures were done at the Laboratory of Botany and Zoology, Faculty of Science, Zagazig University, Egypt, between December 2018 and June 2020.

Methodology: An analysis of the tested BOs components was done using a Shimadzu GC-9A gas chromatograph. Five sub-lethal concentrations of each plant were prepared (5 replicate/treatment) to evaluate medium lethality against A. ipsilon larvae (20 larvae/replicate). Untreated larvae were used distilled water only as a control. Ten larvae of each treatment were treated with only one LC50 to estimate the effect of different tested BOs on anti-nutritional Activities.

Results: The main component of the M. longifolia and A. judaica oil was Piperitone at 39.79 and 37.55%, respectively; whereas the M. hortensis, O. syriacum, and A. santolina oil was Terpinen-4-ol, Thymol, and Fragranyl acetate at 29.82, 31.21, and 25.67%, respectively. According to LC50 of the tested BOs, the toxicity of A. judaica, M. longifolia, O. syriacum, respectively, were the most effective oils, while M. hortensis and A. santolina oils were the least susceptibilities. The more toxic oils reduced food consumption, causing a significant decrease in relative consumption rate (RCR), growth rate (RGR), and efficiency of conversion of ingested food (ECI)/digested (ECD). The previous oils also showed a significant increase in metabolic cost (MC) and anti-feeding activities against A. ipsilon larvae compared to M. hortensis and A. santolina.

Conclusion: It is suggested that A. judaica and M. longifolia extracts contain high Piperitone content and could be accepted as toxicants to control A. ipsilon.

Introduction: The Chilika lagoon in south Odisha, India was ecologically degraded from 1985 onwards by reduction of its aquatic (fish + prawn + shrimp) catches along with reduction in salinity, hydraulic regime, water exchange, aquatic weeds invasion, and sediment influx. The aquatic catch was 8669MT in year 1985-1986 gradually reduced to 1274MT during 1995-1996 from Odisha Fisheries Dept. records which resulted in poor economic condition of ≈0,2million fishermen and they migrated to adopt other livelihood. One direct tidal inlet dredged (Sipakuda) and Naraj barrage in the apex of South Mahanadi Delta were the major hydraulic interventions made to regain hydraulic regime. After the hydraulic interventions, the eco system restored, and the aquatic catch surged but it was insufficient to livelihood sustenance for the fishermen community of the Chilika,     so   that  they are forced for alternate occupation and migration.

Methodologies: Fish catch data collected for 30 years and soft computing models linear regression, Multi Linear Perception (ANN), SMOorg (SVM) and the Random Forest algorithms (Weka Software) are used to predict the fish catch data of the lagoon for coming decade from 2020 to 2030. The effects of major hydraulic interventions are analyzed and the soft computing method of the fish and shrimp catch prediction of the Chilika has been attempted for the first time except some statistical approaches.

Results: The Random Forest is found to be the preferred algorithm followed by the MLP model. The amount of catch remained around 12-13TMT if the variables and the present status of the lagoon is maintained. The combined effect of the Sipakuda Tidal inlet and the effective operation of the Naraj barrage have maintained the sustainable aqua catch. The present study shall be an immense help for the lake users and policy makers to augment aquatic catch, and alternate livelihood fishers community of the Chilika lagoon.

Aims: An experiment was conducted to analyze the DNA fingerprinting and genetic diversity of nine potato (Solanum tuberosum L.) somaclonal variants and three check varieties.

Place and Duration of Study: The experiment was carried out at the Biotechnology laboratory of the Department of Biotechnology, Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh during November, 2013 to December, 2014.

Methodology: The somaclonal variants investigated were SIP-3, SIP-5, SVP-6, SVP-18, SVP-19, SVP-25, SVP-55, SVP-56 and SVP-68, while the check varieties were Cardinal, Diamant and Asterix. Six RAPD primers were used to perform PCR reaction after genomic DNA was extracted from young leaves.

Results: The selected 6 primers produced total 54 distinct and differential amplified DNA bands of size range 88 bp to 3265 bp, where 47 bands (~87%) were polymorphic and 7 bands (~13%) were monomorphic. The pair-wise inter-genotype similarity indices were ranged from 61.59% to 93.55% with an average of 74.31%. The Nei’s genetic distance among 12 potato genotypes was estimated from 0.0972 to 0.6217 whereas, genetic identity was between 0.5370 and 0.9074. Here, the distantly linked accessions among the somaclonal variations with check varieties were SVP-6 (to Cardinal and Diamant) and SVP-25 (to Asterix). In addition, the UPGMA dendrogram segregated the 12 potato genotypes into two broad clusters containing 8 and 4 genotypes, respectively. Furthermore, the dendrogram also displayed the highest genetic distance between SVP-6 vs SVP-68 genotype pair.

Conclusion: Significant relationship and diversity were found among the studied 12 genotypes. This genetic diversity among the potato genotypes would be utilized for further potato improvement.

Soybean (Glycine max (L) Merr.) planted in land space among stands of other crops especially forest trees experience shading stress due to less sunlight penetration. The objective of the study was to identify the performance and yield stability of soybean genotypes in various shading environments. Field research was conducted in 2018 on 15 soybean genotypes consisted of 12 promising soybean lines and three check varieties (Dena 1, Dena 2, and Grobogan) in 10 shading environments (cassava, maize, orange, teak, eucalyptus, oil palm, and no shading). Randomized block design and repeated four times was used in each location. Result of the study showed that the response of the genotypes to grain yield was significantly difference in each environment or location. Stability of genotypes were grouped into 3, namely 1 genotype classified as unstable and recommended for less optimal environments, 6 genotypes (5 promising lines and 1 check variety) which were classified as stable and adaptive in 10 test locations, and 8 genotypes (6 promising lines and 2 check varieties) classified as unstable in 10 test locations. Based on seed yield and yield components average, one line (Grob/Pander-395-2) had a high average seed yield (1.84 tha-1), high seeds weight per plant (14.8 g), high weight of 100 seeds (21.6 g), and stable in 10 location (indicated by non significant both regression coefficient and regression deviation). Therefore, Grob/Pander-395-2 could be recommended for being grown in shading environments across the country.
