Impact of various moisture regime on selected growth-production characteristics of Medicago sativa L. and Trifolium pratense L.
Article Details: Received: 2019-04-08 | Accepted: 2019-06-03 | Available online: 2019-06-30https://doi.org/10.15414/afz.2019.22.02.52-57The aim of the experiment was to find out the impact of different moisture regime on selected indicators of the growth and production process of Medicago sativa L. cv. Zuzana and Trifolium pratense L. cv. Poľana. The pot experiment was carried out at the Department of Grassland Ecosystems and Forage Crops, FAFR SUA in Nitra in 2015. There were evaluated two variants of irrigation: 1st – irrigation once a week and 2nd – irrigation twice a week with a single dose of 300 ml of water per pot. The results of the experiment showed a positive effect on the height of Medicago sativa L. and Trifolium pratense L. plants (p = 0.006 and p = 0.316), the number of stems (p = 0.001 and p = 0.002), dry phytomass production (p = 0.001 and p = 0.044) and the quantity of harvest residues of evaluated legume forages (p = 0.100 and p = 0.146) with a general more visible effect under irrigation twice a week. By comparison of both species, irrigation twice a week was more effective for Medicago sativa L. on plant height, number of stems and weight of above-ground phytomass, whereas for Trifolium pratense L. only on the weight of harvest residues compared to irrigation once a week.ReferencesABBERTON, M.

Green fallow soil vs. intensive soil cultivation – a study of soil structure along the slope gradient affected by erosion process
Article Details: Received: 2019-09-19 | Accepted: 2019-10-01 | Available online: 2019-09-30https://doi.org/10.15414/afz.2019.22.03.76-83 The type of slope and its interaction with soil management practices are one of the most important factors affecting soil structure along the slope gradient. In this study, the effects of fallow in greening and intensive soil cultivation both located on slopes on changes soil properties especially soil structure were evaluated. Soil samples were collected from two fields (neighbouring fields) between Trakovice and Bučany villages (Slovakia). The terrain of both fields was sloping with a WN – ES orientation and a slope of <8°. Field 1 is used as arable land with intensive cultivation of crops (IC). In field 2, the fallow in greening (G) was established in 2012 and in 2018 soil samples were taken in five zones of both slopes as follows: on the summit slope, shoulder, back slope, toe slope and flat. Results showed that structure coefficient (K) was strongly affected by both land use (p = 0.0000) and slope position (p = 0.0206)as well as by the interaction of land use and slope position (p = 0.0010). The statistically significantly highest structure coefficient of water-stable aggregates (Kwsa) and opposite the lowest macro-aggregate destruction (PAD) were found for G compared to IC. In G, the index of crusting (Ic) increased by 9% compared to IC. The critical level of soil organic matter (St) was strongly affected by both land use (p = 0.0114) and slope position (p = 0.0000). The values of St were statistically significantly influenced by interaction of land use and slope position. When land use and slope position were assessed together, positive significant correlations were observed between silt and carbonate contents and Ic. On the other hand, the St values were strong effected soil organic matter (SOM) quantity and quality. In IC, positive correlations between CL (r = 0.773, P <0.01) and K were observed. Ic correlated with silt (r = 0.650, P <0.05), carbonates (r = 0.704, P <0.05) and lower humus stability. A higher silt and carbonate contents as well as highercontent of SOM and better humus quality resulted in higher St values. In G, the K values positive correlated with silt and carbonate contents. Higher humus quality and stability improved soil structure evaluated on the base of Kwsa.Keywords: intensive cultvation, greening, fallow, slope gradient, soil structure ReferencesAMÉZKETA, E.

Differences in soil properties and crop yields after application of biochar blended with farmyard manure in sandy and loamy soils
Article Details: Received: 2018-07-07 | Accepted: 2018-01-18 | Available online: 2019-01-31https://doi.org/10.15414/afz.2019.22.01.21-25In recent years, the importance of biochar application in world´s soils have increased tendency mainly due to its opposite effects. Therefore, the effort of many companies is based on the development of soil amendment which together improved properties and crop productivity in a lot of soils. In this short study, we have verified the effectiveness of biochar blended with farmyard manure named Effeco on soil properties and crop yields in different textural soils (1. sandy soil in Dolná Streda and 2. loamy soil in Veľké Uľany). Our results showed that the Effeco increased soil pH in both soils. In sandy soil, the Effeco more significantly affected sorptive parameters and soil organic carbon content than in loamy soil. Water retention in capillary pores after Effeco application in sandy and loamy soils was higher by 22% and 4%, respectively compared to control. On the other hand, more significant effect of Effeco application on soil structure was observed in loamy soil. The total crop productions in sandy and loamy soils due to the Effeco application were higher by 82% and 16%, respectively, compared to control plots. All in all, we concluded that the effects of biochar blended with farmyard manure differ mainly on soil texture.Keywords: Effeco, sorptive parameters, soil organic matter, water retention, soil structure, loamy soil, sandy soilReferences:Agegnehu, G. et al.

Replacement value of cassava vinasse meal for maize on growth performance, haematological parameters and organoleptic properties of Japanese quails (Coturnix japonica)
Article Details: Received: 2018-10-01 | Accepted: 2018-10-22 | Available online: 2019-01-31https://doi.org/10.15414/afz.2019.22.01.7-12Two hundred and twenty eight (228) one day old quails were used to assess the suitability of cassava vinasse meal (CVM) as a replacement for maize at varying inclusion levels of 0.0%, 5.0%, 10.0% and 15.0%. The birds were fed an adequate starter diet for the first week before being randomly alloted into 4 dietary group of 3 replicate of 19 birds each. The feeding trial lasted for six weeks. The crude protein, crude fibre, ether extract, ash, moisture, nitrogen free extract and metabolizable energy of the dehydrated cassava vinasse were 19.26%, 7.96%, 3.72%, 9.33%, 5.68% and 12.17 MJ kg-1 ME respectively. The results showed that final weight, average daily weight gain and feed conversion ratio were significantly (P <0.05) influenced as inclusion level of cassava vinasse meal increases. Significant differences were observed on the haematological parameters such as haematocrit and mean corpuscular volume (P <0.05). The analyzed panelist response on organoleptic parameters showed that tenderness, juiciness and texture were significantly different (P <0.05) with birds fed 10.0% CVM having the least values. In conclusion, 10.0% CVM (21% replacement for maize) in the diet of quails had no deleterious effect on the feed conversion ratio, haematological parameters and meat acceptability. Moreover, further research could be geared towards the use of exogenous enzymes and the performance of other poultry species including broiler chicken.Keywords: blood, cassava, quail, sensory properties, vinasseReferencesABU, O.

Productive and physiological characteristics of West African dwarf goats fed cassava root sieviate-cassava leaf meal based diet
Article Details: Received: 2019-01-06 | Accepted: 2019-04-15 | Available online: 2019-09-30https://doi.org/10.15414/afz.2019.22.03.64-70West African Dwarf (WAD) goat is an important livestock and its production is indispensable in the country’s food chain. The WAD goat is a trypanotolerant breed reared mainly for meat. This breed can be bred all year-round, attains sexual maturity early and prolific; thereby satisfying a part of the meat requirement. However, in Nigeria, scarcity, poor utilization of agro-waste and seasonality in feed availability undermines this goat breed in achieving better performance. Hence, the effect for feeding cassava root sievate – cassava leaf meal (CRSCLM) diets on the productive and physiological characteristics of WAD goats were investigated for 97 days. Thirty six (36) WAD goats of about 8–10 months of age and averaging 7.19kg in weight were selected from the College flock for this experiment. The goats were randomly divided into four groups of nine animals each with three goats constituting a replicate. Feed intake and body weight changes were recorded accordingly. Blood samples were drawn from each goat on the last day of the trial and evaluated for haematological, biochemical and electrolyte profiles. Daily feed intke, daily weight gain and feed conversion ratio were not (P >0.05) influenced by the treatment diets. The haematological parameters indicated no significant difference (P >0.05) among the treatment groups. There was significant (P <0.05) difference for globulin (23.80–31.40), Creatinine (0.085–1.025) Cholesterol (97.125–120.46) and alanine aminotransferase (ALT) (13.96–18.22) across the treatment groups. Cholesterol and ALT were significantly (P <0.05) increased with increasing levels of CRSCLM. Globulin and creatinine however did not follow any specific trend with increasing or decreasing levels of CRSCLM. Sodium, potassium and chloride were significantly (P <0.05) different across the treatment groups with sodium being significantly (P <0.05) higher among the treatment groups than the control. The study revealed that CRSCLM in the diet of WAD goats had no deleterious effect on the growth performance and blood indices of WAD goats and could therefore be included in goat diets up to 60%.ReferencesADEWUSI S.R.A. and BRADBURY, J.H.

Identification and relative abundance of native arbuscular mycorrhizal fungi associated with oil-seed crops and maize (Zea mays L.) in derived savannah of Nigeria
Article Details: Received: 2019-07-22 | Accepted: 2019-10-10 | Available online: 2019-09-30https://doi.org/10.15414/afz.2019.22.03.84-89A field survey was conducted to assess root colonization, spore densities and relative abundance of native arbuscular mycorrhizal fungi (AMF) based on morphological aspects. Roots and rhizosphere soil samples were collected from established fields of selected oil seed crops [soybean (Glycine max L.), sesame (Sesamum indicum) and sunflower (Helianthus annuus)] and maize (Zea mays L.) grown in derived savannah agro-ecology of Southwest Nigeria. The mean percentage of AMF colonization across all crops was 60.8%, ranging from 34% to 87.5%, with highest root colonization observed in soybean. The spore densities retrieved from the different rhizospheres were relatively high, varying from 124 to 298 spores per 50 g dry soil, with highest spore densities observed in maize rhizosphere soils. The spore densities in the soil significantly correlated (r = 0.52, and P <0.05) with the root colonization. A total of 4 morphologically classifiable genera (Glomus, Gigaspora, Acaulospora, and Scutellospora) of AMF within the phylum Glomeromycota were detected. The dominant genus was Glomus in all the crops with highest relative abundance of 60.9%, followed by Acaulospora (21.3%) and Scutellospora (12.8%), with lowest relative abundance of AM spores observed for Gigaspora (5%). This study could contribute significantly to a better understanding of AMF community structure in derivedsavannah agro-ecology of Nigeria.Keywords: Arbuscular mycorrhizal fungi, community structure, oil-seed crops, root colonization, spore densityReferencesAZCÓN-AGUILAR, C. and BAREA, J.M.

Analysis of coat quality of Chinchilla rabbit breed
Article Details: Received: 2018-10-25 | Accepted: 2018-11-27 | Available online: 2019-01-31https://doi.org/10.15414/afz.2019.22.01.17-20Between breeders, Chinchilla rabbit is very popular as it has standard body shape and high quality of typically coloured fur. The aim of this study was to analyse quality of Chinchilla rabbit fur. Coat samples were gathered at the National Animal Exhibition in Nitra. We collected samples from three different body areas – those being scapula, back and thigh. Altogether, we obtained 153 samples of different individual animals. We observed different parameters of the fur. Those were – thickness and length of coat, height and width of the undercolour, ticking and height of the guard hair. We found out that average thickness of coat in the examined population was 0.106 mm in the area of scapula; 0.104 mm in the thigh area and 0.113 mm from the back area. Length of the guard hair from area of scapula was 35.8 mm; 37.9 mm in the thigh area and 36.4 mm in the back area. Height of the undercolour was 26.9 mm in the back area, 26.4 mm in area of scapula and 27.6 mm in the area of thighs. Observed width of intermediate colour was 5.1 mm in thigh area; 4.3 mm in back area and 4.8 mm in scapula area. Measured height of terminal black line of hair was 4.7 mm in area of scapula; 5.3 mm in the back area and 5.3 mm in thigh area. The differences among the evaluated body areas were not significant.Keywords: fur, quality, hair, rabbit, ChinchillaReferencesBRUMWELL, W. (1928) The Chinchilla Rabbit – Its Breeding For Profit.

Cytotoxic effect of aluminium ions on unicellular eukaryotic organism
Article Details: Received: 2019-10-08 | Accepted: 2019-11-26 | Available online: 2019-12-31https://doi.org/10.15414/afz.2019.22.04.130-137Aluminium is abundant in nature, food, or water and thus its exposition is part of everyday life. However, overexposure can result in cellular malfunctions. Therefore, the aim of this study was to investigate the effects of aluminium on eukaryotes, with the use of Schizosaccharomyces pombe as model organism. Spectrophotometry at OD600, inductively-coupled plasma optical emission spectroscopy (ICP-OES) and microscopy techniques were used to analyse aluminium responses on the living system. Our results revealed that exposition of increasing aluminium concentrations lead to cell growth inhibition in a concentration dependent manner. Furthermore, aluminium incorporation by the cell from media markedly increased with rising Al concentration. Our results indicate that the yeast self-protection system in the presence of lower Al(OH)3 concentration in the environment avoids to large extent dramatic uptake of aluminium by the cell while cells surrounded by higher aluminium concentrations lose this ability. Supplementation of the growth media with 100 μM Al(OH)3 doubled the amount of Al in the cell compared to untreated control (232 mg/kg vs. 459 mg/kg), whereas addition of 1 mM Al(OH)3 caused more than hundred fold increase of intracellular Al content (27,781 mg/kg). Here we also show that high concentrations of aluminium have an impact on cell morphology leading to cell integrity disruption. Findings presented in this study have the ambition to bring more light in an issue of how aluminium mediates impairments of the living organism.ReferencesANOOP, V.M. et al.

Influence of soil texture and compost on the early growth and nutrient uptake of Moringa oleifera Lam
Article Details: Received: 2019-01-15 | Accepted: 2019-06-03 | Available online: 2019-06-30https://doi.org/10.15414/afz.2019.22.02.26-33Soil is the main reservoir of water and nutrients, and thus controls the availability of most essential plant nutrients for crop growth and establishment. Therefore, a study was conducted at Ladoke Akintola University of Technology, Ogbomoso, Nigeria to investigate the effects of soil texture and compost on early growth of Moringa oleifera (M. oleifera). The experiment was a split plot laid out in a randomized complete block design with three replications. The main treatment comprises of three soil texture; sand, loamy sand, and clay while the sub-plot treatment was compost at four rates of 0, 2.5, 5 and 10 tha-1 per 10 kg of soil and NPK 15:15:15 at the rate of 90 kg Nha-1. Data on plant height, number of leaves, stem diameter were measured at 2 week interval for 10 weeks. Results showed that Moringa plant produced in loamy sand was superior in plant height, number of leaves and stem girth irrespective of compost applied. At 10 weeks after sowing, fresh shoot weights/pot was 73.3, 31.7, 30.3 g respectively for loamy sand, clay and sand. M. oleifera N uptake in loamy sand was significantly (p<0.05) greater by 57 and 50%, respectively, than sand and clay. P uptake was significantly higher at 5 ton ha-1 than the control and other treatments. The study concluded that, combination of loamy sand and 5 ton ha-1 of compost was suitable for the early growth of M. oleifera.ReferencesADEBAYO, A.G. et al.
