With the aim of providing a multi-crop thresher to local farmers, the IAR-sorghum thresher was evaluated using varieties of wheat. Among the factors which were varied in the randomized complete block design experiments used in the evaluation were 2 levels of moisture content, 2 levels on feed rate, 3 levels of cylinder speed and 3 replications of each treatment. The indices used to measure the effectiveness and efficiency of the thresher to process wheat were threshing efficiency, cleaning efficiency, scatter loss from thresher and its output capacity. The fuel consumption rates of carrying the tasks out were also determined for the 2 moisture contents of each variety. These indices translate into the economics qualities and quantities which would influence the acceptance or other of the thresher by targeted farmers. It was found that the thresher could thresh the crop to a threshing efficiency of 95%, cleaning efficiency of 82%, scatter loss of 10% achieved by the thresher was rather high, and the output capacity of 9 kg hr-1 was not satisfactorily. Hence, the recommendation on how to improve on the thresher performance and the rate of fuel consumption were provided.

Borneo sour eggplant, a popular indigenous fruit vegetable in Borneo, has become an important fruit not only to local people, but also to tourists who visit Borneo. One of the challenges in planting this crop is lacking information, particularly in finding suitable media for its growth, eventually inhibiting local farmers from growing the crop commercially. This study was conducted to investigate the effects of 4 growing media compositions (M1: topsoil, M2: topsoil and compost, M3: topsoil and cocopeat and M4: topsoil, compost and cocopeat) on the germination and growth performance of sour eggplant seedlings. The experiment was tested in a randomized complete block design (RCBD) with 10 replicates. At the end of germination period, seeds planted in M4 medium produced the highest germination rate of 96.67% and was significantly different (P < 0.05) from those sown in other growing media. However, the performance of the seedlings in terms of height, stem diameter, number of leaves and length of leaves showed significant increase (P < 0.05) in M2 medium. This study has demonstrated that M2 medium could improve the growth performance of the seedlings and therefore is recommended as suitable growing media for planting sour eggplant. Keywords: Growth performance, growing medium, indigenous fruit, sour eggplant.

Sorghum is a major source of food for most families and as raw material to many industries in Nigeria. Cleaning is among the most important post-harvest operation after threshing. However, manual cleaning of crop is quite tedious, time and labour intensive. A prototype thresher has already been developed at Institute of Agricultural Research (IAR) but yet it has been associated with many difficulties during operation. Among the problems of IAR prototype sorghum thresher are low operating performance such as higher scatter loss and low cleaning efficiency thus the need for modification to improve the above mentioned parameters. This study was undertaken to modify the cleaning system of the IAR sorghum thresher with the aim of minimizing the drudgery involved in its operation and to improve its performance. The major modifications were on shaking mechanism and sieves. The number of sieves was increased from one to three while the connecting rode for shaking mechanism was changed from horizontal to vertical orientation. The sizes of the pulleys were also changed. Randomized Complete Block Design (RCBD) experimental design was used for determining the effect of moisture content, speed and feed rate on the cleaning performance of the machine. The maximum performance achieved were 99.95 %, 5.45 %, and 250 kg/h for cleaning efficiency, scatter loss and throughput capacity respectively.

Aim: This study evaluates the effects of soil amendment with organic manure-OM and agricultural lime-AL on the growth and yield of Phaseolus vulgaris and Vigna aconitifolia grown on soils with 3 different pH (locations) in Southern Cross River State. Study Design: The study was laid in randomized complete block design (RCBD) with three replications. Place and Duration of Study: This study was carried out at the Greenhouse, Department of Plant and Ecological Studies, University of Calabar for a period of 3 months. Methodology: The three locations were: Akamkpa with pH 4.0, Calabar Municipality with pH of 7.0 and Odukpani with pH of 9.0. The treatments were; control (0 g), OM1 (100 g organic manure), OM2 (200g organic manure), AL1 (100 g agricultural lime), AL2 (200 g agricultural lime), OM1 + AL1 (50 g organic manure + 50 g agricultural lime) and OM2 +AL2 (100 g organic manure and 100 g agricultural lime. Results: Results obtained from the physico-chemical properties of the soil before treatment application revealed low nutrients and minerals which increased after treatment application. Six weeks after planting, there were significant increase in plant height (p<0.05) of P. vulgaris and V. aconitifolia on soil from Akamkpa (169.66 cm) and Odukpani (146.63 cm) treated with OM2 + AL2 compared to 43.77 cm and 71.77 cm from control. Leaf area, petiole length, number of leaves were all significantly improved especially at 8 weeks after planting. Fresh weights of leaf, stem and root revealed higher yield (p<0.05) at the final harvest recorded as 8 weeks after planting than the amount at 4 weeks after planting. The results obtained from the pod number, pod weight and number of seed showed significant improvement after treatment application. Conclusion: The findings of this study strongly support the use of organic manure and agriculture lime as affordable and accessible sources of manure especially for our local farmers.

Abstract Automatic feeding systems are being used more frequently to understand individual cattle behavior and intake variation when cattle are group housed. The objective of this experiment was to evaluate if bunk preference exists, and if so, how bunk preference affects performance, intake, or efficiency of feedlot steers. Angus steers (n = 123; initial BW = 293 ± 33.8 kg) were blocked by BW and sire and assigned to 1 of 4 pens, each containing 6 automated feed bunks (Insentec RIC; Hokofarm Group, Marknesse, Netherlands), in a randomized complete block design. Steers were fed a common diet and free to consume feed from any bunk within the pen without restriction. A steer’s preferred bunk was defined as the bunk from which the most feed was consumed. In any week, 80% of steers consumed less than 29% of that week’s total feed intake from the preferred bunk, indicating no strong preference for a specific bunk. The maximum weekly feed intake consumed from a preferred bunk was 57%. Further, the percentage of intake from the preferred bunk did not affect overall ADG, feed intake, or G:F (P &gt; 0.64). These results suggest that a few steers may have a relatively strong preference for a specific feed bunk, however this preference was not associated with performance, intake, or efficiency. Researchers can design experiments (at a stocking density of 5 steers per bunk) that restrict or alter an individual animal’s access to any specific bunk, because such access, or lack of access, does not alter the animal’s performance or feed intake.

An experiment was conducted at a farmer’s field in Bakergonj Upazilla of Barisal district from July 2014 to October 2014 to study the adaptive performance of six aman rice varieties. The varieties included in the study were BRRI dhan62, BINA dhan7, BINA dhan8, BINA dhan10, BINA dhan11, and Maloti (local). The experiment was laid out in a randomized complete block design with three replications. Variety Maloti produced highest plant height (126cm) and BRRI dhan62 produced least plant height (93cm). Variety BINA dhan7 and BINA dhan11 produced highest LAI, total dry matter (g plant-1). Yield of different rice varieties varied significantly. Variety BINA dhan11 gave the highest yield (5.033 t ha-1) which was statistically at par with that of BINA dhan7 (5.00 t ha-1) and BINA dhan8 (4.50 t ha-1), BINA dhan10 (3.933t ha-1), BRRI dhan62 (4.167t ha-1). The highest grain yields of these varieties were obtained to the highest number of bearing tillers m-2. The lowest grain yield (3.50 t ha-1) and straw yield (4.840 t ha-1) were found in Maloti. The shortest period for first flowering (66 days) was observed in BRRI dhan62. Among the varieties, the longest maturity stage (139 days) was observed in local var. Maloti. While the shortest period was observed in BRRI dhan62 (94.5 days). So, the experiment concluded that BINA dhan11 was the highest performing short duration variety followed by BINA dhan7, while BRRI dhan62 and, BINAdhan8, BINAdhan10 performed better among the short duration varieties respectively during aman season to evade cyclonic effect and for cultivating boro rice in Bakergonj Upazilla of Barisal district.Asian J.

Abstract A developmental Bacillus based direct-fed microbial (DFM) was added to nursery pig diets to evaluate the effect on growth and health in two 35-d randomized complete block design experiments blocked on initial BW and sex. Experiment 1 used 315 weaned pigs (20.1 d of age; 6.11 kg initial BW) allotted to one of three diets: 1) Negative Control (NC; no antibiotics but with pharmacological Zn or Cu), 2) NC+DFM 0.55x109CFU, 3) NC+DFM 1.1x109CFU. Experiment 2 used 376 weaned pigs (17.8 d of age; 5.99 kg initial BW) allotted to one of four diets, the same 3 diets from Experiment 1 plus a lower inclusion rate: 4) NC+DFM 0.275x109CFU. Both studies had 15 replicates/treatment, 6–7 pigs/pen. Pigs were budget fed phase 1–3 diets (1.13 kg/pig; 2.72 kg/pig; and 6.35 kg/pig, respectively) and ad libitum fed Phase 4 diet to d35. For Experiment 1, during week 1 pigs fed the DFM tended to linearly decrease ADFI (P = 0.086) and linearly increase G:F (P = 0.085). During day 21–35 of Experiment 1 pigs fed DFM linearly increased ADG (P = 0.035) and quadratically increased ADFI (P = 0.027). Overall for experiment 1, ADG (P = 0.114) and ADFI (P = 0.104) tended to quadratically increase and G:F linearly increased (P = 0.012) with increasing concentrations of DFM. Experiment 2; during week 1 and 3 ADFI (P = 0.084, P = 0.050, respectively) quadratically increased and G:F (P = 0.081; P = 0.022, respectively) quadratically decreased as DFM increased in the diet. During d21–35 of experiment 2, ADG (P = 0.064) quadratically increased and G:F (P = 0.012) quadratically decreased as DFM increased. Overall for Experiment 2 ADFI numerically increased (4.3%) with no increase in ADG, resulting in a quadratic decrease in G:F (P = 0.010) as the DFM increased in the diet. Summarizing these two studies, the DFM product had its greatest effect increasing ADFI while inconsistently impacting gain and efficiency.

Abstract Randomized complete block design experiments (n = 6 experiments) were conducted in large-pen feedlot research facilities between 2015 and 2018 comparing an 80 mg trenbolone acetate (TBA) and 8 mg estradiol-17β (E2) initial implant and re-implant with 200 mg TBA and 20 mg E2 protocol (IH/200) to a single 80 mg TBA and 8 mg E2 uncoated; 120 mg TBA and 12 mg E2 coated implant at arrival (XH) on growth and carcass responses in finishing heifers. Experiments occurred in Nebraska, Oklahoma, Washington, and Texas. Similar arrival processing was used across experiments where 17,675 heifers [initial BW = 333 kg SEM (4.1)] were enrolled into 180 pens (90 pens/treatment with 65 to 240 heifers/pen) and fed for 152 to 214 d. Only IH/200 heifers were removed from their pen at re-implant. Diets contained monensin and tylosin, consisted of ingredients common to each region, and contained greater than 90% concentrate. Ractopamine hydrochloride was fed for a minimum of 28 d prior to harvest. Linear mixed-models were used for all analyses; model-adjusted means for each implant group and the corresponding SEM were generated. Distributions of USDA quality (QG) and yield grade (YG) were analyzed for ordinal outcomes. No differences (P ≥ 0.11) were detected for any performance parameters except DMI, where XH had greater (P = 0.02) DMI (9.48 vs. 9.38 ± 0.127 kg) compared with IH/200. Heifers implanted with IH/200 had greater (P ≤ 0.02) HCW by 1.3%, caused by greater dressing percentage, and ribeye area; lesser (P ≤ 0.01) back fat by and calculated YG, while marbling scores were similar (P = 0.74) compared with XH heifers. Distributions of USDA YG and QG were impacted (P ≤ 0.03) by treatment, IH/200 had fewer USDA Prime and YG 4 and 5 carcasses. These data indicate that heifer growth performance did not differ between implants, but HCW and muscling did; IH/200 is suited for grid marketing and XH is suited for heifers sold on a live basis.
