Abstract: The objective of this work was to evaluate the agronomic performance of cowpea (Vigna unguiculata) genotypes over three crop years, in the ecosystem of Rio Branco, in the state of Acre, Brazil. The experiments were carried out in the 2016, 2017, and 2018 crop seasons, in a randomized complete block design, with four replicates. Eight agronomic traits were evaluated in 14 cowpea genotypes, which included: 12 lines (BDO 1-5-11, BDO 1-5-15, BDO 1-5-19, BDO 1-5-24, PDO 1-5-26, PDO 1-5-4, PDO 1-5-5, PDO 1-5-7, PDO 1-5-8, PDO 1-5-10, PDO 1-5-11, and PDO 1-5-14) and two cultivars (BRS Tumucumaque and BRS Imponente). A significant difference was observed in the genotype x crop year interaction, for most traits. Although there was no statistical difference between genotypes in the studied crop years, dry seed productivity was higher than the national average. All cowpea lines and cultivars from the genetic breeding program show equivalent and favorable agronomic performances in the environmental conditions of Rio Branco. Therefore, these genotypes can be selected for incorporation into the production system of Rio Branco.

The Relationship

Cashew (Anacardium occidentale L.) is an important tropical cash crop cultivated in Ghana. It provides livelihood for about 200,000 people and contributes 6.1% to Ghana’s gross domestic product (GDP). Four Brazilian dwarf accessions were introduced to improve nut yield. Objectives of this study were to (1) assess the agronomic performance of the accessions across two contrasting ecologies, (2) determine environmental influence on juvenile growth, (3) determine the relationship between early vegetative growth and yield and (4) explore heritability and genetic advance for the measured agronomic traits. The experiment was laid out in a randomized complete block design with 3 replications. Results revealed significant (p < 0.05) environmental influence on growth and yield of cashew. Transitional savanna agro-ecology is more suitable for cashew growth and development. Crop year, location and crop year × location interactions also influenced most of the agronomic traits. Early growth characteristics alone were not enough to predict yield. Genotype B2 ranked highest yielding across the agro-ecologies. Moderate to high heritability and genetic advance estimates were observed for nut yield, plant height and girth, an indication of variability among accessions needed for cashew improvement in Ghana.

Haricot bean (Phaseolus vulagris L.) is an annual crop cultivated for food as it has high protein content. The objective of this study was to evaluate yield and yield-related traits of haricot bean varieties at the Dollo University research site. Five released and four local haricot bean varieties were used on 3 × 2 m (6 m2) experimental plots using randomized complete block design with three replications. Data pertaining to agronomic traits and yield performance of each variety were recorded and analyzed using R software version 4.0.5 and Microsoft Excel 2010. One way multivariate analysis showed a significant difference (p <0.05) in thousand seed weight. SAB-632, Local-4 (‘Burree’) and SAB-736 showed higher yield than the other haricot bean varieties. They are also high in all agronomic traits except SAB-736. Thousand seed weight and yield were high and significant with positively correlated to each other. Plant height had a high and significant positive correlation with the number of branches and seeds per plant. Generally, it is possible to say that haricot bean varieties, SAB-632 and Local-4(‘Burree’) are preferable in yield at the Dambi Dollo University research site according to the present findings. Therefore, it is good if these two haricot bean varieties are practised for multiplication at Dambi Dollo Research site and other related agro ecologies.

This study was conducted to investigate the effect of bacterial bio-fertilization A. chroococcum and P. putide and four levels of compost (0, 1, 2, 3) tons.h-1 on the leaves content of N.P.K elements. The experiment was carried out in one of the greenhouses of the College of Agriculture - University of Al-Qadisiyah during fall season 2018-2019. It designed in accordance with the Randomized Complete Block Design (RCBD) with three replicates in sandy loam soil. The means of treatments were compared with the least significant difference (LSD) at (5)% probability level. The results present that the treatments of A. chroococcum, P. putide and compost at (3) tons.kg-1 significantly increases the leaves content of K.P.K compared to all other treatments in the flowering stage (4.970, 0.5000, and 4.930) mg.kg-1, respectively. This treatment was followed by the effect of the treatment of A. chroococcum and compost at (3) tons.kg-1, which increases the values of all traits except the leaf content of (P). Bio-fertilizer with P. putide + A. chroococcum significantly increases the leaves' content of P.

ABSTRACT: In the last few cropping seasons, some soybean producers have tested the application of a hill drop sowing method, usually from three to four seeds every 30 to 40cm. However, there is a lack of information in the literature about the effect of this practice on soybean performance. Thus, the objective of this study was to evaluate the effect of a hill drop sowing with different number of plants per hole on soybean performance. The study was conducted in Londrina - PR, Brazil, during the 2013/14, 2014/15 and 2016/17 cropping seasons. The experiment was a randomized complete block design with four replications and a 2x5 factorial scheme. The first factor consisted of two soybean cultivars, BRS 359RR and NK 7059RR analyzed in the first two cropping seasons and BRS 359RR and BRS 1010IPRO in the last cropping season. The second factor was constituted by five in-hill hole-spacing treatments (HS) (8, 16, 24, 32 and 40cm), with rows spaced 50cm apart. To maintain the same plant density in all treatments (270,000 plants ha-1), sowing was performed manually, being then thinned out. After thinning, the distribution was one plant per hole at HS8, 2 plants at HS16, 3 plants at HS24, 4 plants at HS32, and 5 plants at HS40. The agronomic performance of soybean in hill drop sowing with different number of plants per hole is similar to that of an equidistant distribution of plants.

This experimental study was conducted to determine the effect of unilateral nephrectomy on kidney function through hematological and urological values after surgery using feral domestic cats.  Four (4) apparently healthy stray male cats were caught and used as experimental animals in this study. The animals were grouped into two (2) with two cats in each group. Grouping of the animals was based according to age, the 1st group – ages one year and above (>1 year) and the 2nd group – ages one year and below (<1 year).  A split plot randomized complete block design was used in the experiment. The result shows that rectal temperature and packed cell volume have been affected on both age group of cats and other urological values like the presence of urobilinogen, protein, leukocytes, erythrocytes and crystals were elevated twenty four hours after surgery. A significant increase on the level of creatinine and blood urea nitrogen has been noted from the 3rd and 15th post – operative day. However, no significant difference was noted between experimental animals and the two age groups, all of which have similar result. The findings of the study revealed that the remaining kidney could not completely compensate the function of the other kidney up to the 15th post – operative day, it may take longer than fifteen days. Hence, proper supportive treatment, post-operative care & management of animals subjected to unilateral nephrectomy is a must and should continue beyond fifteen days.

A field study was conducted at Tennessee State University's research station to evaluate the effect of hardwood bark mulch on the winter survival of garden mums. A randomized complete block design was used. Cultivars used were adorn, encore, grandchild, jackpot, legend, minnautumn, minnwhite and triump. At the end of the flowering season the tops were removed leaving a four inch stubble in the mulch. The number of mum plants that resumed growth the following spring were counted for each cultivar. There was a difference in the winter survival of the different cultivars as well as a significant difference in the mulch treated and the control. Grandchild and jackpot were most cold hardy followed by encore, minnwhite, minnautumn, triump, legend, and adorn. Grandchild and jackpot with four inches of hardwood bark mulch had an 88 percent survival while the control had a 44 percent survival. Adorn. had a 51 percent survival with four inches of mulch and a 20 percent survival in the control. This data shows that hardwood bark mulch holds a great potential for providing excellent winter protection for garden mums.

This research involved ninety-six S1 maize lines with the opaque-2 gene that carne from populations 63 (26 lines), 65 (12 lines), and 68 (58 lines) from the CIMMYT maize breeding programo The S1 lines selected in the laboratory because of their high lysine content were crossed with five testers that had a different genetic base: a synthetic variety, two early lines derived from this variety, and two single intermediate crosses of normal performance. The test crosses were evaluated and compared with five control s (two commercial and three experimental hybrids) using a randomized complete block design in two sites in Mexico during 1992. The objecti ves of this research were to select SI lines in early generations according to their agronomic performance, grain lysine content, and GCA grain yield, and to compare testers' efficiency in discriminating S1 lines. On average, the SI lines of population 63 showed a greater grain yield as compared to that of populations 65 and 68 combined with all testers, except in the case of the synthetic tester YS- 201-M. A line from population 65 combined with tester B3 x B5 showed the highest grain yield (10,23 t ha-I), representing a superiority of 4% above the best commercial hybrid, AN- 447. A total ofthirty-one Sllines were selected based on their agronomic attributes and grain yield: 13, 14, and 4 from populations 63, 65 and 68 respectively]. Tester B3 x B5 tumed out to be the best line discriminator according to the following criteria: grain yield, percentage of ears damaged by Fusarium spp., and number of rotten ears.

Abstract This study examined the effect of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid (SILOHealth™ 104L [monoglycerides]) and avilamycin on day 14 and 21 post weaning performance of E. coli (GN-Ent and O157:H7) day 5 challenged piglets fed corn/soy diets that met or exceeded current NRC (2012) recommendations. A total of 96, Choice Genetics CG32, piglets were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (4 piglets/pen x 3 treatments x 8 replications). Pigs were blocked by sex and weight and were orally dosed with 5 ml (1x109 CFU/g, strain GN-Ent and O157:H7) E. coli d 5 after weaning (Ec). The treatment were: NC with Ec; T1=NC + 3 kg/MT monoglycerides; T2=NC+ 80 ppm avilamycin. Least significant difference was used to compare means of treatment. Mortalities and pen removals were weighed and recorded. The E. coli infection model was effective in causing E. coli mortality of 25% at d14 post weaning and 33% at d21 post weaning in NC. T1 and T2 reduced mortality versus NC at d14 (25, 3 and 0%, P < 0.05) and d21 (33, 4 and 0%, P < 0.05), increased ADG at d14 (203, 255 and 259 g, P < 0.05) and d21 (456, 511 and 515 g, P < 0.05), decreased FCR at d21 (1.90, 1.85 and 1.83, P < 0.05), and decreased intestinal E. coli, log 10 of CFU/g, versus NC (4.1, 2.2 and 2.1, P < 0.05). Monoglycerides and avilamycin performance, mortality and intestinal E. coli log 10 were not significantly different at P < 0.05. In conclusion, the use of monoglycerides improved ADG, reduced FCR, reduced mortality and reduced intestinal E. coli log 10 at day 14 and 21 post weaning versus NC and monoglycerides were not significant different (P < 0.05) than avilamycin.

Set Up

Four advanced tritordeum lines were studied and compared to two commercial varieties of tritordeum and wheat cultivars in yield and quality features, in Greece. For this purpose, a two-year experiment was established in the Greek territory. The field experiment was set up in Randomized Complete Block Design (RCBD) with blocks, with different lines and varieties. Head emergence was calculated based on Growing Degree Days (GDDs), which was significantly affected by the year. The significance of differences between treatments was estimated by using Fisher’s least significant difference (LSD) test with significance level p = 0.05. The weight of 1000 seeds of the two commercial varieties differed from the equivalent weight of 1000 seeds of tritordeum lines, approximately 1 g. Yield was significantly affected by lines/varieties and year. Compared to tritordeum yield, wheat yield marked the highest values. This difference was almost 2 kg ha−1. Gluten content was significantly affected by lines/varieties. The highest gluten content was firstly noticed at wheat GENESIS (34.2%) variety and secondly at tritordeum Aucan (33.2%) variety. Protein was higher in tritordeum lines HT-1704 (15.5%), HT-1707 (15.1%) and Aucan variety (15.2%) during the first experimental year. Tritordeum seems to have significant adaptability to dry conditions in Greece and significant yields compared to the existing commercial varieties and bread wheat.

Sorghum Bicolor L

Forage sorghum [Sorghum bicolor L. Moench 'Brown midrib' (BMR)] and annual legumes lablab [Lablab purpureus L. 'Rongai' (L)] and mucuna [Mucuna pruriens L. 'Vine 90 d' (M)] are suitable fodder for the dairy industry in Puerto Rico, but BMR harvested at 90 days, usually has low crude protein (CP, 6%) content, which limits its usefulness. There is the possibility of increasing the CP by intercropping legumes with BMR, but this option has been only slightly investigated. This study proposes to compare BMR in monoculture and in intercropping with 'Rongai' (SL) and 'Vine 90 d' (SM), in addition to L and M in monoculture, in terms of total leaf mass (FM) and botanical components (sorghum, legumes and weeds) and chemical (CP and fiber fractions) at two harvest times. The experimental plots (25 m2) were sown in February and August 2008 in a randomized complete block design with five replications. At each harvest time, 2 m2 MF area was sampled 90 days after sowing. Data were analyzed by using the MIXED procedure of SAS and mean separation tests were performed by using F-protected LSD at 95% level of confidence. No significant differences (combining fodder botanical component and weeds) were detected for the total MF between BMR and BMR associated with legumes in monoculture, with mean values of 8.94, 8.81, and 8.42 Mg/ha for BMR-'Rongai', BMR-'Vine 90 d', and BMR, respectively. Overall, there was no significant difference in MF between May and August (8.1 vs. 7.5 Mg/ha). 'Rongai' yield (Mg/ha) did not change between May and August (3.6 vs. 3.0) but was lower in the intercrop (2.74) than in monoculture (3.94). 'Vine 90 d' had the lowest yield of 2.8 and 1.3 Mg/ ha in May and August, respectively. No differences (P > 0.05) in NDF and ADF content between BMR and BMR-'Rongai'-'Vine 90 d', whose values were 60.1 and 63.9% and 40.1 and 46.5%, respectively. However, differences (P < 0.05) were found in CP content between monoculture and intercropping, with values of 14.1, 11.1, and 6.0% for 'Rongai', 'Vine 90 d', and sole BMR, respectively, whereas the BMR-'Rongai' and BMR- 'Vine 90 d' CP were 9.8 and 9.1%, but these last values exceed by three units the percentage in BMR. In conclusion, BMR intercropped with 'Rongai' and 'Vine 90 d' improved the forage chemistry and helps to control weeds while favoring the performance of desirable botanical components.
