Aims: To evaluate the effects of organic amendment in the rehabilitation of two moribund cacao plantations at Ibadan (Oyo State) and Owena (Ondo State) using organic materials that included Cocoa Pod Husk (CPH) and Neem Leaf powder (NL). Study Design: The experiment was laid out in a Randomized Complete Block Design in four replicates with four treatments which were CPH, CPH+NL (90:10), CPH+NL (80:20) and untreated. Place and Duration of Study: Cocoa plantations at Ibadan and Owena, Nigeria between May, 2014 and Dec 2017. Methodology: Initial soil sampling was done. Organic materials were applied to eight cacao trees in a ring at the base of trees in treated plots at the beginning of the rains in April/May and August/September. The treatments are: CPH Only @ 0.5 kg/tree, CPH Fortified with Neem Leaf (90:10) @ 0.45 kg + 0.05 kg/tree, respectively, CPH fortified with Neem Leaf (80:20) @ 0.40 kg + 0.10 kg/tree respectively. No application (control treatment). Results: Eleven fungi species assigned to seven genera were recovered across the treatments. Organic amendments significantly (p<0.05) increased soil mineralization, microbial populations and pod production. After the second year of applications, CPH had the highest percentage of pod production over the control (64%) in Ibadan, while in Owena, CPH, CPH+NL (80:20) and CPH+NL (90:10) had percentage pod increase of 68, 64 and 63%, respectively, over the control. Organic materials had significant (p≤0.05) effect in raising the soil pH in the two locations from 6.41 to 6.82 in Owena and from 6.50 to 6.89 in Ibadan, compared to untreated soil. Conclusion: The use of organic amendments in the rehabilitation of old and moribund cocoa (near death), improved soil nutrients as well as increased pod production and the microbial populations from the two plantations.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.

ABSTRACT Mechanizing the harvest of Jalapeño pepper involves changes in the production system. Spacings between plants in rows (10 to 40 cm; 60 cm fixed between rows) were evaluated in relation to plant architecture, productivity and fruit quality of cultivar BRS Sarakura during three years, in a randomized complete block design with five replicates. Productivity (41.9 to 78.8 t ha-1) and plant height (40.1 to 47.3 cm) responded linearly to density; on the other hand, productivity per plant responded negatively (0.48 to 1.04 kg plant-1). The stem first bifurcation height was little influenced. Fruit chemical analyses were carried out in the second year of the experiment; spacing significantly influenced pH (5.36 to 4.84), total titratable acidity (TTA) (0.48 to 0.36%) and total soluble solids (TSS)/TTA ratio (11.5 to 15.6); no influence on TSS (5.65%) was noticed, though. The increase of plant population provided an increase in productivity without affecting fruit quality; the highest height of the first bifurcation achieved may not be enough to enable mechanized harvesting of the cultivar BRS Sarakura.

Currently in Mexico there are few studies on agronomic management in olive production. The objective of this experiment was to evaluate eleven olive cultivars for table and oil production (Arbequina, Koroneiki, Arbosana, Kalamata, Barnea, Pendolino, Empeltre, Manzanilla of Sevilla, Carboncella, Frantoio and Cassaliva) under hot and arid environment of Mexico. The experiment was carried out during two consecutive years in 2015 and 2016 at National Research Institute for Forestry, Agriculture and Livestock (INIFAP) in the Experimental Station of Caborca, Sonora, Mexico. The plantation was done on March, 2012 using a density of 100 trees ha-1 (10 x 10 m) under drip irrigation system. The parameters evaluated were vegetative parameters, yield, fruit quality and oil content. The experiment was analyzed using a randomized complete block design and five replications. The results showed statistical differences for all parameters evaluated. Arbequina obtained the highest olive yield with 34.5 and 70.3 kg per tree for the first and second year production, respectively and Barnea recorded the highest oil content with 19.2%. Finally, Manzanilla of Sevilla and Barnea varieties represent a good option as double-purpose varieties.

The effect of different rates of boron application on wheat cv. Bijoy was studied through a field experiment at    Bangladesh Agricultural University (BAU) farm, Mymensingh during 2009-10 rabi season. The BAU farm belongs to    Old Brahmaputra Floodplain agroecological zone (AEZ 9). Texturally the soil was silt loam, with 7.2 pH, 0.81%    organic matter and 0.15 mg kg-1 available boron content. The experiment was laid out in a randomized complete    block design with five boron rates and four replications. Boron rates were 0, 0.75, 1.5, 2.25 and 3.0 kg ha-1, with boric    acid as a source. Every plot received blanket doses of 115 kg N, 25 kg P, 75 kg K and 15 kg S ha-1 from urea, TSP,    MoP and gypsum, respectively. Treatment receiving B @ 2.25 kg ha-1 produced the highest grain yield (4.22 t ha-1) which was statistically identical with that obtained with 1.75 kg B ha-1. However, the crop response curve showed    1.90 kg ha-1 to be the optimum boron rate for the maximization of wheat yield. The lowest grain yield (2.84 t/ha) was    recorded with control treatment. There was a positive relationship between grain yield and number of grains spike-1.   Boron had significant influence on N, P, K, S and B uptake by the crop which, in deed, was more influenced by crop    yield and less by nutrient concentration, except N and B uptake where concentration had more influence than yield.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.10987   J.

Abstract This study presents a novel find of a Feed NSPase Enzyme, Natugrain TS, reducing finish pig hemorrhagic bowel syndrome (HBS) mortality. A total of 3,750 weaned pigs (28 kg), (PIC 337 x Camborough), 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 (25 pigs/pen x 5 treatments x 30 replications). Pigs were blocked by sex and weight and were fed mash corn/soy/DDGs diets formulated to meet or exceed current NRC (2012) recommendations. Treatments were T1= 0 g/MT Natugrain TS, T2= 100 g/MT Natugrain TS, T3= 150 g/MT Natugrain TS, T4= 200 g/MT Natugrain TS and T5= 250 g/MT Natugrain TS. At the finishing phase, Natugrain TS significantly decreased intestinal E. coli log 10 (7.12, 4.95, 4.02, 3.21 and 3.25 log 10, P < 0.05, respectively), significantly decreased intestinal lesion score (0–5 score) (4.21, 4.02, 2.98, 2.25 and 2.26, P < 0.05, respectively). Microbiota was analyzed in fresh, manually collected, rectum fecal samples. Microbiota was separated into prevalent in Natugrain TS control (0) and 200 g/ton. In the control treatment, there was a prevalence of Desulfoyibrio, Oscillospira, Campylobacter, Anearoctruncus, Mogibacterium and Brachyspirae, etc., while in the 200 g/ton treatment there was a prevalence of Synergistales, Burkolderiales, Dehabacteriaceae, Bifidobacterium, Roseburia, Lactobacillus and Bacilli, etc. Natugrain TS significantly decreased mortality (4.8, 3.6, 2.7, 1.9 and 2.1 %, P < 0.05, respectively), significantly decreased specifically HBS mortality (3.50, 1.98, 0.68, 0.40 and 0.46%, P < 0.05, respectively). In conclusion, Natugrain TS changed the microbiome by breaking down arabinoxylans, decreasing intestinal E. coli and intestinal lesion score, changing the microbiota to prevalent Bifidobacterium, Roseburia, Lactobacillus and Bacilli, and Natugrain TS up to 200 g/ton specifically decreasing hemorrhagic bowel syndrome mortality from 3.5% to 0.5%.

Abstract One of the factors limiting crop growth is weeds. The weeds lead to a reduced performance of the crops. Chemical control methods are considered appropriate for controlling weeds. Therefore, in the fight to control weeds in triticale, the performance of the dual-purpose herbicide sulfosulfuron(Apirus®), mesosulfuron + idosulfuron(Atlantis®), metsulfuron methyl+sulfosulfuron(Total®) with surfactant and isoproton + diflufenican(Panther®) from the sulfonylurea group, and narrow leaf herbicides clodinafobpropargyl( Topik®), pinoxaden(New Axial®), diclofop-methyl(Iloxan®), pinoxaden + clodinafob-propagyl (Traxos ®), fenoxaprop-pethyl + mefen-pyper-d-ethyl(PumaSuper®), tralkoksidim(Grasb®) with 1 liter oil, flam-prop-m-isopropyl(Suffix BW®), and control treatment without herbicides were evaluated. The test was carried out in a randomized complete block design with four replications. Spraying was carried out using a back sprayer. For evaluation of ocular damage, the European Weed Research Council (EWRC) standard method was used. According to the performed studies, the narrow leaves of wild oat and barnyard grass were the dominant weeds. Results showed that all herbicide, except the herbicide tralkoksidim, were effective in weed control. The triticale yield was maintained with the use of these herbicides and none of herbicide had an adverse effect on the crop. In the first weeks of herbicide use, the triticale leaves appeared pale but this problem resolved over time. It seems that the herbicides discussed in this paper can be used on the triticale plant.

<p>Improper intercropping of <em>Elaeis guineensis</em> with other crops has impaired the growth and development of the oil palm due to competition for environmental resources. The study was conducted to investigate the impact of intercropping on the growth of juvenile oil palm for 2 years. The research commenced during the rainy season of 2016 at an established juvenile oil palm plantation in Ala, Akure-North Local Government of Ondo State. Four fruit vegetables were intercropped separately within the alley of the plantation at 1, 2 or 3 m away from the oil palms in a randomized complete block design. Growth parameters of the juvenile oils were assessed. Results revealed that at 16 weeks after intercropping (WAI), the intercropped oil palm recorded better growth performance with higher canopy spread, number of frond, number of leaflets and trunk height (218.20, 37.00, 87.48 and 38.17 cm) respectively, than the sole oil palms (214.67, 32.83, 72.89 and 31.67 cm) respectively. There were no significant difference in all the growth parameters examined except canopy height (<em>p</em> &lt; 0.05). Juvenile oil palm cultivated in rainforest agroecological zone of Nigeria can be intercropped with fruit vegetables without any deleterious effect when intercropped at minimum of 1 m away from the oil palms.</p>

Dietary intake of a variety of vegetables is very important for disease prevention and may help in the treatment of certain maladies. Experiments were conducted to evaluate yield and the content of antioxidants and phenolics of vegetable Amaranth (Amaranthus hybridus), Celosia (Celosia argentea), Gboma (Solanum macrocarpon), and Long Bean (Vigna unguiculata) in response to poultry litter (PL) and a hydrolyzed fish fertilizer [Megabloom (MB)]. The experiments were conducted as a randomized complete block design with a four × three factorial treatment and four replications. The treatments were applied based on soil test recommendations in a single band 15 to 20 cm away from the plants 1 week after transplanting. Plants were harvested sequentially during the season as foliage and fruits became physiologically mature and once over at the end of the season. Species were analyzed for vitamin C content, total phenolics, and β-carotene content as well as antioxidant capacity. Organic amendments did not significantly influence biomass production, whereas species impacted fresh and dry biomass. Amaranth, Celosia, and Long Bean produced greater fresh and dry biomass than did Gboma. Vitamin C content was highest among Amaranth and Celosia plants receiving nitrogen–phosphorus–potassium (NPK) compared with the other two treatments, whereas that of Gboma was higher among plants receiving MB.
