{"title":"PHENOTYPIC CHARACTERIZATION OF INDIGENOUS FREE RANGE CHICKENS IN KALOMO, ZAMBIA","authors":"S. Liswaniso, N. Qin, X. Shan, X. Sun, R. Xu","doi":"10.36899/japs.2023.3.0658","DOIUrl":"https://doi.org/10.36899/japs.2023.3.0658","url":null,"abstract":"The study was conducted in Kalomo district of Zambia to phenotypically characterize indigenous chickens in the area in order to initiate the base for strategic improvement of the indigenous chickens. In this study, 476 chickens (245 males and 231 females) were used. The phenotypes were recorded through observation by the researcher while quantitative traits were measured using the tailor’s measuring tape as guided by the FAO guide. Out of 476 birds, 85.29% had normal feathers. The most common shank color was gray-blue (29.41%) with the single comb type being the most dominant (91.18%). The red-white earlobe color was predominant (44.12%). Brown eyed chickens were the most common (52.93%). Body weight was taken using a digital scale. There was a significant difference (P˂0.05) in body weight between males and females, males being heavier than the females (2331±587grams and 1586±245grams, respectively). The overall average body weight was 1969±589grams. There was significant (P˂0.05) positive correlation between all linear body measurements with body weight. Two principal components PC1 (54.50%) and PC2 (11.28%) were extracted which both cumulatively accounted for 65.78% of the total variability. The first principal component accounted for 54.50% of variance and had high significant loadings on all body measurements except for shank circumference. We, therefore, theorize that PC1 can be exploited as selection standards for body weight improvement in Zambian indigenous chickens. The many variations found in this study indicated the huge potential that indigenous chickens have for improvements through selection and good breeding strategies","PeriodicalId":17736,"journal":{"name":"June 1","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79612562","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}

It grows well on calcareous slopes, and produces a fragrant essential oil. The aim of study was to evaluate foliar application of gibberellic acid (GA 3 ) and delaying harvesting for different durations on essential oil and components of English lavender after foliar treatment with 0, 200, 400 and 600 mg l -1 gibberellic acid (GA 3 ). Clevenger apparatus-based water-vapor distillation method was used to determine essential oil and its components by GC-MS. The experiment was established in split plots in randomized complete block design with two factors and 3 replications. The main plots were formed at harvest time and the sub-plots were created by GA 3 applications. Statistical analyzes were made using MSTAT-C package program. When the GA 3 doses and harvest times interaction were evaluated together, the average essential oil yield of the harvested lavender flowers ranged 6.20 to 8.20 % showing the prominent influence of the concentration of GA 3 and delay in harvesting (in hours) on concentrartration of alkaloids. More than 50 components were identified, the most important among these was 1.8-cineole, linalool, camphor, borneol, lavandulol, and terpinene-4-ol. The amount of linalool, which improves the quality of the essential oil ranged 34.49-38.75%. The minimum and the maximum essential oil values were noted from the flowers harvested after 30 hours (control treatments), and 54 hours from 400 mg l-1 GA 3 treated plants in the same order. However, essential oil contents showed a slight decrease at higher GA 3 treatments and prolonging duration of harvest after respective GA 3 treatments. GA 3 treatments enhanced the quantity of essential oil substantially, and the optimal dose was determined as 400 mg l -1 GA 3 on samples harvested after 54 hours following application. The results further showed that the quantities of essential oil's primary components varied according to harvest time.","PeriodicalId":17736,"journal":{"name":"June 1","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88738673","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}

The experiment was carried out in both kharif and rabi season of the years 2019-20 and 2020-21. The experiment was laid out in a split plot design with four nutrient management practices in rice viz. recommended dose of fertilizer (RDF), RDF + 25% additional phosphorus(P) through FYM, RDF + 25% additional phosphorus(P) through fertilizer and 75% of RDF (RDF75) in main plots and five nutrient management practices in greengram viz. Control, RDF, RDF + PSB inoculation (RDF+ PSB), RDF + Foliar spray of 2% DAP (RDF + FS) and RDF + PSB inoculation + Foliar spray of 2% DAP (RDF + PSB + FS) in subplots and replicated thrice. Effect of system based phosphorus management had significant effect on productivity, profitability and nutrient uptake by the system. Application of 25 % additional phosphorous to rice through fertilizer improved the rice equivalent yield (REY) and P uptake of the rice - greengram system by 6.6 and 7.1% compared to the application of recommended dose of phosphorus to rice. The same treatment also resulted in significantly highest net returns and B:C ratio from the cropping system compared to all other treatments including application of 25% additional phosphorus through FYM. However, application of PSB and foliar spray of 2% DAP along with recommended dose of phosphorus to greengram improved the REY and P uptake of the system to the tune of 23.4 and 21.3%, respectively, compared to non fertilized plots where as 6.2 and 9.6%, respectively, over recommended dose of P to greengram with highest net return and B:C ratio. Further, application of 25% additional phosphorus through FYM or fertilizer along with RDF to rice followed by application of PSB and foliar spray of 2% DAP along with RDF to greengram produced the highest grain and straw yield, nutrient uptake, gross return, net return and B:C ratio.","PeriodicalId":17736,"journal":{"name":"June 1","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79359501","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}

Application of fertilizers based on the Nutriexpert was (112-31-58) higher nitrogen, lower phosphorus and potassium than the recommended dose of fertilizers (90-60-60) during kharif season for rice. The treatments included recommended fertilizer (T1), Site Specific Nutrient Management (SSNM) based on Nutrient expert (T2), SSNM based on Leaf Colour Chart (50% N as basal and rest 50% based on LCC (T3), T2 minus Nitrogen (T4), T2 minus Phosphorus (T5), T2 minus Potassium (T6), Absolute control (without N, P and K) (T7) and Farmer's Practice (T8) . The results revealed that the highest grain yield (6317 kg ha-1) and straw yield (7663 kg ha-1) of rice was recorded in T2- SSNM (NE) which is significantly superior over all other fertilizer treatments. Application of major nutrients based on nutriexpert recorded higher uptake of nitrogen (128.50 kg ha-1), phosphorus (27.15 kg ha-1), and potassium(137.32 kg ha-1). Nutrient omission and control treatments recorded significantly lowest grain and straw yields of rice and also nutrient uptake.

Phenotypic coefficient of variation exhibited higher values but maintained close relation with genotypic coefficient of variation for all the traits. Additive gene action was prominent for traits like plant height, panicle length, number of filled grains per panicle and 1000 grain weight. A correlation study showed that grain yield per plant was positive and significantly correlated with tillers per plant, panicles per plant, number of filled grains per panicle, total number of filled grains per plant and 1000 grain weight. The principal component analysis revealed that total number of filled grains per plant had a strong relation with grain yield.
