Effect On Yield

Seaweed extract has been reported to have various beneficial effects on many crops. A study was conducted in 1989 and 1990 to evaluate the effects of Response 9-9-7, a seaweed extract fortified with NPK, on yield of staked tomatoes and cucumbers. Plants were sprayed to the runoff weekly, biweekly, every 3 weeks and every 4 weeks with 1:500, 1:250, 1:150 and 1:125 v/v Response/water respectively. Results indicate that spring tomatoes sprayed with Response 9-9-7 at all rates outyielded the check which was sprayed with plain water. However, the only significant difference was obtained when tomatoes were sprayed with 1:150 Response/water in 1989 and 1:500 in 1990. Response/water at 1:500 rate significantly increased the quality and marketable yield of cucumber in both years. Response 9-9-7 had no effect on yield of tomatoes grown in the summer under heat stress.

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.

N-3 polyunsaturated fatty acids (PUFAs) have been suggested to affect depressive disorders. This review aims to determine the effect of n-3 PUFAs on depressive symptoms in people with or without diagnosed depression. Medline, PsycINFO, and Cochrane CENTRAL databases were searched for randomized controlled trials (RCTs) assessing the association between n-3 PUFAs and depressive symptoms or disorders as outcomes. A random-effects meta-analysis of standardized mean difference (SMD) with 95% confidence intervals (CI) was performed. Twenty-five studies (7682 participants) were included. Our meta-analysis (20 studies) indicated that n-3 PUFA supplementation lowered depressive symptomology as compared with placebo: SMD = −0.34, 95% CI: −0.55, −0.12, I2 = 86%, n = 5836, but a possible publication bias cannot be ruled out. Subgroup analyses indicated no statistically significant difference by treatment duration of <12 vs. ≥12 weeks, presence of comorbidity, or severity of depressive symptoms. Nevertheless, beneficial effects were seen in the subgroups of studies with longer treatment duration and with no depression and mild to moderate depression. Subgroup analysis by eicosapentaenoic acid (EPA) dosage revealed differences in favor of the lower EPA dosage. Sensitivity analysis including studies with low risk of bias seems to confirm the overall result. Supplementation of n-3 PUFA appears to have a modest beneficial effect on depressive symptomology, although the quality of evidence is still insufficient.

Abstract This study was conducted to evaluate effects of chilled drinking water and cooled floor pads on behavior of lactating sows under heat stress. Sows were housed in individual farrowing stalls in two rooms with temperatures being controlled at 29.4°C (0700h to 1900h) and 23.9°C (1900h to 0700h). Sows in one room (treatment), but not in the other room (control) were provided with chilled drinking water (13 to 15°C) and cooled floor pads (15 to 18°C). Behavior of sows (n=15 sows/treatment; parity=1 to 6) was video recorded during farrowing, and d 1, 3, 7, 14, and 21 after farrowing. Videos were viewed to register birth time of each piglet. Number of drinking bouts and duration of each bout were registered for 2 h (1530h to 1730h) each day after farrowing. Postures (lying laterally, lying ventrally, sitting, and standing) were recorded by scanning video-recordings at 5-min intervals for 24 h each day after farrowing, and time budget for each posture was calculated. Data were analyzed using the Glimmix Procedure of SAS. No effect of treatment was detected for litter size born, farrowing duration, or birth interval (P &gt;0.33; Table 1). Neither frequency nor duration of drinking bouts was affected by treatment (P &gt;0.27). No significant difference was observed in time budget for each posture (P &gt;0.46) between treatment and control groups. As lactation progressed, sows increased drinking frequency (from 1.2 drinks/2h on d 1 to 4.9 drinks/2h on d 21; P&lt; 0.001) and time spent lying ventrally (8% to 14%; P&lt; 0.0001), standing (4% to 10%; P&lt; 0.001), and sitting (2% to 4%; P&lt; 0.0001), and decreased time spent lying laterally (86% to 67%; P&lt; 0.0001) in both control and treatment rooms. These results indicate that chilled drinking water and cooled floor pads did not affect behavior of sows during farrowing and lactation in the current study.

The research was conducted to study the effect of heat stress on carcass characteristics and meat quality in indigenous sheep. Nine sheep were divided into three groups which were almost similar in age, sex and weight. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure to direct sunlight. During experimental period temperature–humidity index (THI) value was calculated as 27.09 which indicated T4 and T8 groups were subjected to heat stress condition for at least four hours and eight hours respectively every day. Slaughter weight, body length and heart girth had no significant difference among the treatment groups. Dry matter, ash and ether extract had no significant difference (p>0.05) among the treatment groups but crude protein were increased with the increase of heat stress from T0 to T8 group (p<0.05). Drip loss was increased (p<0.05) in non-exposure group than treated groups but there is no significant result (p>0.05) found in pH and cooking loss. Carcass weight and eye muscle area had no significant difference (p>0.05) among the treatment groups but dressing percentage was decreased with the increase of time in heat treated groups (p<0.01). Significant difference (p<0.05) were found in weight of heart, kidney, lung + trachea and pluck between control and heat treated groups. The significant difference (p>0.05) in empty gut was found in gut with content and gut fill in heat treated groups. It can be concluded that heat stress had significant changes on carcass characteristics and meat quality of indigenous sheep.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20717 Bang. J. Anim.

The aim of this research was to observe the effect of heat stress on milk yield and milk compositions of Holstein Friesian crossbred (HF) dairy cows. To fulfill the objectives, a total of 9 Holstein Friesian crossbred cows were selected for this study. Green grasses (German, Para) were supplied adlibitum and concentrate feeds (mixture of wheat bran, rice polish, mustard oil cake, di-calcium phosphate and salt) were supplied at the rate of 2.0 kg/day/cow. Management practices for all the cows were similar following the BAU Dairy farm practices. Data were collected on milk yield (l/h/d), relative humidity (%) and barn temperature (0C). The obtained temperature humidity index (THI) of July, August, September and October were 84.95, 81.99, 81.40 and 79.57, respectively. The highest THI was found in July which indicated higher heat stress during this month. A significant difference (p<0.05) in milk yield of cows was found among different months of July to October. The highest milk yield (6.10±0.50 l/h/d) was found in October among observed months. The compositions of milk such as total solids (TS), solids-not-fat (SNF), fat, protein, lactose, and ash also differed significantly (p<0.01). The highest values (%) of TS, SNF, fat, protein, lactose and ash content of milk were found in October as 12.63, 8.80, 3.83, 3.69, 4.39 and 0.72, respectively and lowest values (%) were in July as 12.20, 8.50, 3.71, 3.50, 4.30 and 0.69, respectively due to the high THI value. From these results, it is concluded that heat stress has strong effect on milk yield and milk composition of HF cows in Bangladesh. Management strategies are needed to minimize heat stress and attain optimal dairy animal performance.Asian J. Med. Biol. Res. June 2016, 2(2): 190-195

<em>Saligrama</em> otherwise called <em>Shaligram</em> or <em>Salagrama</em> is a fossilized shell stone usually recovered from the banks of the Gandaki river in Nepal. It is supposed to be a sacred symbol of Hindus. Soaking the stone in water for twenty to thirty minutes and partaking the water was considered to give good health. Hence, we mobilized two stones which were authorized as original by experts. The first one was worshipped for more than 5 years and the other one for two years. The water soaked was around 25 ml which was analysed for antioxidant activity by DPPH assay with plain water without soakage as control. The antioxidant property was significantly found in both the stones with more activity in the stone worshipped for more than 5 years. We did not standardize the volume and the duration of soakage to exact values while it was approximated to around 20 – 30 minutes. We suggest more refined studies with estimation of rare elements needs to be performed to establish the beneficial effects of this sacred <em>saligrama</em> stone.

Aims: This study aimed to determine the effective percentage of telang leaf meal on feed to increase antioxidant levels in tilapia liver feed. Study Design: A total of 12 aquariums with sizes 60 x 40 x 40 cm3and volume 96 L prepared and filled with 30 L water. Heater was installed and the temperature was raised slowly until it reached 34℃. Feed in the form of a mixture of telang leaf flour and commercial feed was given 3 times a day according to treatment and with the provisions of 3% of body weight of fish per day. Analysis of antioxidant levels was analyzed from the content of the superoxide dismutase enzyme as an antioxidant bioindicator in the body of the fish. Place and Duration of Study: The cultivation was carried out at Ciparanje Hatchery and Fisheries Area, Faculty of Fisheries and Marine Science, Universitas Padjadjaran and Dismutase Superoxide Level Analysis was carried out at the Central Laboratory of Universitas Padjadjaran in June and July 2019. Methodology: This research was carried out by giving high temperatures as a source of stress, for 40 days. Tilapia were given a mixture of telang leaf meal as a source of anti-oxidants. At the end of research, Test liver fish taken superoxide dismutase levels were observed and analyzed descriptively. Daily growth and survival rate of fish were analysed using F test at 5% level, and if there were significant differences, Duncan's test was performed. Results: By giving heat stress continuously for 40 days the result is obtained the highest average superoxide dismutase level in treatment B (telang leaf meal 5%) as much -0.92 inhibition and lowest in treatment D (telang leaf meal 15%). A decrease in SOD levels identifies a decrease in antioxidant activity in the body of Tilapia. Daily growth rate obtained showed no significant difference. The fish will continue to grow but not as rapidly, because tilapia utilize protein up to 40% of commercial feed used to repair cells damaged during stressful periods and as a source of energy. Survival of fish decreases with increasing concentration of telang leaf flour, where the feed given has been mixed and resulted in the fish's response to the feed decreases, consequently not only the fish adapted to the environment, fish also adapt to new types of feed. Conclusion: Based on the results of research that has been done then conclusions can be drawn that the addition of telang leaf mealup to 15% in commercial feed by giving heat stress since the beginning of the culture period does not provide an effect of increasing antioxidant levels.

Chipping Potato

The cost of seed accounts for nearly 10% of the estimated production cost of chipping potato (Solanum tuberosum) production in Florida. Optimizing seed piece spacing can reduce costs without affecting potato yield. This study evaluated the effects of seed piece spacing on yield, quality, and economic revenue of chipping potato production in north Florida. A field experiment was conduct during the spring of 2013, 2014, and 2016 in Hastings, FL, with a split-plot randomized complete block design. In-row seed piece spacings of 10, 15, 20 (industry standard), 25, and 30 cm were assigned as the main plot and S. tuberosum potato cultivars (Atlantic, Harley Blackwell, and Elkton) as the subplots. Marketable tuber yield ranged between 10.8 and 15.2 Mg·ha−1 in 2013, 10.1 and 12.8 Mg·ha−1 in 2014, and 9.9 and 19.7 Mg·ha−1 in 2016. Overall lower yields in 2013 were due to three freeze events early in the season. Widening seed piece spacing resulted in a linear decrease in total and marketable yield in 2013 and 2014. Conversely, seed piece spacings of 10 and 15 cm showed lower marketable yields in 2016. There was no interaction between in-row spacing and cultivar in any year tested. Cultivars performed variably across years for total and marketable yield and specific gravity. Tuber specific gravity was unaffected by seed piece spacing, except in 2013, when 25 and 30 cm resulted in slightly higher values. There was no significant difference in total and marketable yield between the industry standard seed piece spacing 20 and 25 cm in any year. In-row spacing of 25 cm in 2013 and 30 cm seed piece spacing in 2014 and 2016 provided the greatest economic return. Net revenue can be increased by adjusting the in-row seed piece spacing from the commercial standard of 20 to 25 cm, which reduces production cost without negatively impacting yields.

Sensorimotor Performance

Abstract Background: Music-supported therapy (MST), a type of biofeedback therapy with multi-sensory information input, has been proposed as an effective approach to improving motor control in people with sensorimotor deficits. However, currently, MST training is restricted to being extensively applied for patients with various levels of defects in fine motor skills and cognitive functions. Therefore, the integration of passive haptic learning (PHL) with MST has been adopted as a motor training strategy intended to enhance “motor memory” learning through the use of vibration stimuli. The current study was designed to investigate differences in the sensorimotor performance of older adults’ hands under baseline, a single session of standard MST, and PHL-based MST conditions. Methods: Thirty healthy older adults were recruited and randomized to receive either the single session of 30-minutes of PHL-based MST or 30-minutes of standard MST at the beginning of the experiment. After a one-week washout period, they switched their treatment programs and then were assessed to study the training effects of both approaches through measuring precision pinch performance, hand function, and sensory status. Results: The results of the Pinch-Holding-Up Activity test revealed a statistically significant difference in the FRpeak parameter (F = 14.37, p < 0.001, η² = 0.507) under the PHL-based MST condition compared to the baseline and standard MST conditions. In addition, significant beneficial effects were found on the results of the barognosis (F = 19.126, p < 0.001, η² = 0. 577) and roughness differentiation subtests (F = 15.036, p < 0.001, η² = 0.518) in the Manual Tactile Test for the participants in the PHL-based MST group. In addition, the participants under both the standard MST and PHL-based MST conditions exhibited better performance in the three subtests of the Purdue Pegboard Test as compared to under the baseline condition (p < 0.016). Conclusions: The findings indicated that PHL-based MST potentially improves the precision pinch performance of hands in healthy older adults. In addition, the add-on effect of vibrotactile stimulation to the MST condition provides beneficial effects on the sensory functions of the upper extremities.
