Angora Goats

There is increasing interest in the diversification of animal production systems to produce products which are not in surplus nationally. Fine fibre production from goats is one such subject area. Previous studies (e.g. Huston, 1980; Calhoun et al, 1988) in other countries have suggested that the yield and quality of mohair fibre may be influenced by nutritional factors such as protein and energy. The aim of the work reported here was to investigate the effects of differences in dietary protein and energy on body growth and yield and quality of mohair fibre produced by British Angora goats.Twenty four male castrate British Angora goats of Australasian origin with an initial liveweight of 23.5 kg were used in a 112 day study. The goats were housed in individual pens and introduced to pelleted diets over a period of three weeks. The animals were allocated to four dietary treatments by randomised block design according to liveweight. The animals received diets containing, per kg dry matter, concentrations of estimated metabolizable energy of 10.2 MJ (LE) or 11.9 MJ (HE) and crude protein concentrations of 108 g (LP) or 180 g (HP) in a 2 x 2 factorial experiment. The animals were offered high energy diets (30 g/kg liveweight) which were increased when live weight increased by 1.0 kg. The goats on the low energy rations were offered amounts equivalent to 0.85 of the ME intake from HE diets. The live weight gain and food intake were recorded weekly.

Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

There is a developing interest in the use of fibre-producing goats in the United Kingdom. Information on nutritional requirements under UK conditions and for different genotypes of goats is limited. The aim of this study was to investigate further the role of dietary protein in determining the yield and quality of (a) mohair Fibre and (b) meat with emphasis on fat composition in Angora goats.Ten Texan cross male castrate Angora goats aged about 10 months and weighing 21.6 kg initially were used. They were individually penned and allocated to good quality diets containing (per kg dry matter (DM)) approximately 10 MJ metabolisable energy and either 110 (LP) or 178 (HP) g crude protein. The diets were restricted to intakes of 37 g/kg liveweight (LW) and the study lasted for 70 days. The goats were weighed weekly and food intake was recorded daily. Blood samples were collected pre-feeding by jugular venepuncture at approximately 0900 hrs on day 0, 35 and 70 and at 07.30,09.00,10.30,12.00 and 13.00 hrs on day 63.

Crop bio-life is used as a foliar spray to enhance the symbiotic effect between roots and soil micro-organisms enabling the plant to better assimilate nutrients essential for growth. The aim of the study was to assess the effect of crop bio-life on growth, yield and quality of wild okra. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. The experiment consisted of four treatments. The treatments were different crop bio-life concentrations of 0, 25, 50 and 75 ppm.  The highest plant height (103.5 cm) was obtained in plants treated with 25 ppm crop bio-life and the lowest plant height (91.2 cm) was in plants treated with 75 ppm crop bio-life. Plants with the highest chlorophyll content (29.08 µmol per m2) were those treated with 50 ppm crop bio-life while the lowest (18.6 µmol per m2) was 0 ppm treatment.  The highest wild okra yield of 22.3 g leaf wet mass was obtained in plants treated with 25 ppm crop bio-life and the lowest yield (12.9 g) obtained from plants applied with 75 ppm crop bio-life. From the results of this study, it was observed that the plants treated with 25 ppm crop bio-life grew better and had a higher yield, therefore, it is the treatment recommended to farmers.

Cultivation of cauliflower with bio-slurry and phosphorus fertilizer was done as an effort to improve soil fertility to increase growth and yield of cauliflower. The study was conducted to determine the effect of bio-slurry with phosphorus fertilizer on growth and yield of lowland cauliflower. The experiment was carried out at Agrotechnopark of Jember University screenhouse from February to May 2018. The research method used a Randomized Block Design (RBD) with split plot enviromental design on 3 levels of bio-slurry factor and 4 levels phosphorus factor was repeated 3 times. The first factor was liquid bio-slurry consisting of no bio-slurry; 500 ml bio-slurry / plant; 1000 ml of bio-slurry / plant. The second factor was phosphorus fertilizer (TSP) consisting of 0 g / plant; 1.5 g / plant; 3 g / plant; 9 g / plant. The experimental results showed that the interaction between the bio-slurry dose and phosphorus fertilizer had a significant effect on the yield and quality of the flowers except for the fresh weight of the flower. The treatment of TSP fertilizer affects growth except for chlorophyll content and total leaf area. The bio-slurry treatment can increase the fresh weight of cauliflower.Keywords:cauliflower, bio-slurry and phosphorus

There is an immense need to replace chemical fertilizers with biofertilizers to address the soil, environment, and health issues. Endophytic bacteria act as biocontrol agents and promote plant growth and yield. Present study was designed to evaluate the microbial effect of endophytic bacteria on growth, fruit yield and quality of phalsa (Grewia asiatica L.). Three years old healthy, disease and insect-pest free plants were selected for the study. Experiment was laid out in randomized complete block design with four treatments; control, two bacteria such as Burkholderia phytofirmans strain PsJN, Bacillus sp. strain MN54 and their combination (PsJN + MN54) with three replications. The treatments were applied after pruning (January) and flowering (March) as plants need nutrition for both vegetative and reproductive growth. Combined application of PsJN + MN54 resulted in greater vegetative and reproductive growths of plants i.e. number of shoots/plant (29.6), number of leaves/shoot (15.9), number of fruit clusters/shoot (14.0), number of fruits/cluster (14.1), fruit weight (13.7 g) and yield/plant (8.8 kg) than PsJN or MN54 alone and control. Fruit biochemical characteristic i.e. TSS (8.78 °Brix), TA (0.53%), ascorbic acid (44.44 mg 100 mL-1), total sugar (12.29%), reducing sugar (9.59%) and non-reducing sugar (4.92%) contents were also higher in plants treated with PsJN + MN54. All growth, yield and biochemical parameters correlated positively with each other except titratable acidity. Based on performance, the combined treatment (PsJN + MN54) can be applied at two stages, after pruning and at flowering, for better growth, yield and quality of phalsa crop.

Different crops have variations in their responses to applied micronutrients in soil. A study was conducted on floodplain soil of Bangladesh to explore the response of potato to application of micronutrients in soil. The experimental site was located at farmers’ field in Chandina upazila under Cumilla district of Bangladesh covering the soils of Old Meghna Estuarine Floodplain (AEZ 19) during 2011-12. Randomized complete block design with 3 replications of each treatment was used in the experiment, where seven treatments including a control were tested. Additive element trial technique was followed while designing the treatments taking six micronutrients i. e. Zn, B, Cu, Mn, Fe and Mo at the rate of 3, 2, 2, 3, 5 and 1 kg ha-1, respectively. Macronutrients, such as N, P, K and S were applied at recommended rates to all plots. The highest tuber yield (28.7 t ha-1) was produced by the combined application of Zn and B. Only Zn application was sufficient to obtain the highest content of protein as well as content of almost all the nutrients in potato tuber. Antagonistic relation between Zn and P in soil-plant system was recorded in the study. Zinc and boron application influenced different growth and yield parameters of potato while the other four added micronutrients did not have any significant effect but combined application of Zn, B, Cu, Mn, Fe and Mo had beneficial role for better plant growth and production. Proper management of zinc and boron fertilizers including optimization of application rates of those nutrients can help to uphold the yield and quality of potato in floodplain soil. SAARC J.

Growing Conditions

Brinjal is a crop grown widely all over India and preferred by both rich and poor. The Chhotanagpur plateau of Jharkhand is famous for quality vegetable production and brinjal is very commonly grown in this region almost throughout the year. However, the most of the commercial growers using plant protection chemicals and synthetic fertilizers those are so expensive that poor farmers can’t afford. The extensive uses of agro-chemicals and synthetic fertilizers also reduce the quality of both the produce and the cultivated soil. In this context, an attempt has been made through the present investigation by growing different varieties of brinjal by adopting Vedic (Enriched Sanjeevani) Farming and Homa Induction (Agnihotra) techniques with their respective four non-chemical alternative growing approaches, viz.  E1C1: Enriched Sanjeevani (1%), E1C2: Absolute Control (inherent fertility status of the experimental plot); E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra). Five varieties of the crop, viz. V1: Swarna Pratibha; V2: Swarna Neelima; V3: Swarna Shakti; V4: Mukta Jhuri; V5: Long Green were grown with their four replications under four growing conditions and the Randomized Completed Block Design was adopted for field trials. Different growth, yield and quality attributing characters of the crop were taken into account and findings revealed that E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) was the most suitable growing condition for V2 (Swarna Neelima) with the maximum yield (72.37 t ha-1). Different growth and yield attributes of the crop varieties (especially in the case of V2: Swarna Neelima) were highly influenced by Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) [E2C1] growing condition resulting higher benefit cost ratio of 6.78. Quality contributing attributes were also highly influenced by homa induction (Agnihotra), as a consequence, higher level of dry matter, TSS, and ascorbic acid contents were estimated from almost all samples collected from E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra) growing conditions.

Economic use of organic and inorganic fertilizers following their availability is necessary for livestock-based Nepalese farming systems. However, how best to integrate these fertilizers in an appropriate manner is not yet clear. Thus, this study was conducted in the horticulture farm of the Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal from November 2018 to February 2019 to evaluate the effect of organic and inorganic sources of nitrogen (N) on growth, yield, and quality of beetroot (Beta vulgaris L.) varieties. The experiment was laid out in a two factorial randomized complete block design with four replications consisting of two beetroot varieties, i.e., Madhur and Ruby Red, and five N source combinations, i.e., N1: 100% poultry manure (PM), N2: 50% PM + 50% urea, N3: 100% farmyard manure (FYM), N4: 50% FYM + 50% urea, and N5: 100% urea (120:80:40 kg NPK ha−1). Results of this study indicated a significant impact of N sources and varieties on the assessed parameters. During harvest, a significantly higher plant height (41.84 cm), number of leaves per plant (14.68), leaf length (34.56 cm), leaf width (11.38 cm), and beetroot diameter (72.15 mm) were observed in the N2 treatment. Likewise, higher economic (49.78 t ha−1) and biological yields (78.69 t ha−1) were also recorded in the N2 compared to other N sources. Out of the two varieties, the Madhur variety was significantly better in most growth and yield parameters. Similarly, the Madhur variety showed a significantly higher economic (44.49 t ha−1) and biological yields (69.79 t ha−1) compared to the Ruby Red variety. However, the physiological weight loss was higher in the Ruby Red variety. Therefore, the current study suggests that an integration of poultry manure along with the combination of N fertilizer and the Madhur variety is the best combination for quality beetroot production in the Terai region of Nepal.

AbstractTen Scottish male castrated cashmere-yielding (C) and 10 Angora (A) goats with initial live weights of 38·2 (C) and 32·1 (A) kg respectively were used in a 112-day study in the time period August to December. The goats were blocked within genotypes according to live weight and randomly assigned to one of two treatments: either no supplementation (O) or dietary supplementation (S) with 2·5 g/kg dry matter (DM) intake of rumen-protected intestinally available methionine (Smartamine™ M, Rhone Poulenc, Animal Nutrition, Antony 92164, France) in a 2 × 2 factorial arrangement.The goats were offered a basal diet in the proportion of 0·6, grass hay and 0·4 concentrate according to their live weight. Diet metabolizable energy (ME) and crude protein (CP) concentration per kg DM were estimated as 9·9 MJ (ME) and 107 g (CP) and DM intake was restricted to 28 g/kg live weight daily. Apparent digestibility and nitrogen (N) balance studies were conducted from days 24 to 40 and 51 to 64. Measurements were made within three time periods of days 0 to 40, 41 to 75 and 76 to 112.Angora goats excreted less urinary N than cashmere-yielding goats and had lower values for plasma urea and glucose and greater overall retention ofN, associated with a two- to three-fold greater total fibre yield. Cashmere as a proportion of total fibre by weight, (guard hair plus cashmere) varied from 0·27 to 0·43.The main effects due to methionine supplementation were improvements in live-weight gain and food conversion ratio. Reductions in urinary N excretion and increases in N retention were recorded, which were generally greater for Angora than for cashmere-yielding goats, and were again associated with the larger responses in fibre production. Clear evidence was also obtained for methionine-induced increases in the weight of raw cashmere, although not guard hair up to day 58. This response was obtained in the absence of significant effects on cashmere diameter, although methionine supplementation consistently increased the average diameter of mohair fibres.
