Orange Fleshed Sweet Potato

The research work conducted at the Teaching and Research Farm of University of Abuja was aimed at assessing the effect of Moringa oleifera, selected leguminous plants and inorganic fertilizer on the performance of orange fleshed sweet potato in Alley Cropping System. Randomized Complete Block Design (RCBD) using five treatments with three replications was applied. Data collected include: percentage survival of sweet potato, length per vine (cm), number of leaves per vine, leaf area of sweet potato, weed dry matter (g/m2), yield of sweet potato roots. Highest number of leaves (28) per plant was recorded in the control plot while the plots with NPK fertilizer had the highest length per vine (94.55cm) though not significantly (p>0.05) different from others. Higher percent survival (88%) of sweet potato was recorded from control plots. Stands grown in Arachis hypogeae plots produced the highest leaf area (0.202m2) while plots in which NPK fertilizer was applied experienced highest weed dry matter (4.083g/m2) although highest root yield (1.2t/ha) was recorded from the plots with NPK fertilizer.

<p><em>Cauliflower is one of the vegetables for consumers. The demand for cauliflower was rising so it must be scaled up with fertilizer. The purpose of this study was to study the effect of chicken manure and NPK fertilizer on the growth and yield of cauliflower. The study was conducted in Sukasenang Village, Banyuresmi Sub-district, Garut Regency from July to August 2019. The study used a Randomized Block Design (RBD) in two factors each of the 3 rates with 2 replications. The first factor was the rates of chicken manure which consisted of 0, 10 and 20 tons ha<sup>-1</sup>; the second factor was NPK fertilizer which consists of 0, 100 and 200 kg ha<sup>-1</sup>. The parameter of this research was plant height, number of leaves, leaf area, weight and diameter crud. The results showed that there was no interaction between the chicken manure and NPK fertilizer. The treatment of 20 tons ha<sup>-1</sup> chicken manure affected the variable plant height, the number of leaves and leaf area. The rates of 200 kg ha<sup>-1</sup> NPK fertilizer had affected plant height, number of leaves, weight and diameter crud.</em></p>

An experiment was conducted to evaluate the yield of forage, silage and nutrients composition of two maize accessions: West Atlantic Seed Alliance 1 (WASA1) and an accession from Shika tagged (SHIMAZ). The maize seeds were planted in plots of 5 m x 5 m (25 m2) size with four replicates for each accession. The results showed that, there was no significant (P > 0.05) difference between the accessions for plant height and number of leaves at 4, 6, 8 and 10 weeks after sowing (WAS), but leaf area index (LAI) was significantly (P < 0.05) higher in SHIMAZ accession at 6 and 10 WAS. The number of leaves per plant, green leaves, leaf area and forage yield at 91, 105 and 119 days after sowing (DAS) were not significant (P > 0.05) in the two accessions of maize, but leaf area and LAI were significantly (P < 0.05) higher in WASA1 accession.. The percentage dry-matter (DM) content was significantly (P < 0.05) lower in WASA1, although leaf, and stem ratios were significantly (P < 0.01) higher at various stages of harvest. The crude protein (CP) and nitrogen free-extract (NFE) were significantly (P < 0.01) higher in WASA1 accession while crude fibre (CF) was significantly (P < 0.01) higher in SHIMAZ. The proximate components (ash, EE and CP) and NDF were significantly (P < 0.01) higher in WASA1 silage, but NFE and ADF were higher (P < 0.05) in SHIMAZ accession.

Glyphosate Drift

ABSTRACT Chemical ripeners are frequently used on sugarcane crops in order to increase profitability. However, the drift of these products to neighbouring fields can expose susceptible non-target plants, such as sunflower, to these agents causing indirect impacts on growth and development. Therefore, this study aimed to assess the toxicity characterize possible changes in the growth of sunflower plants exposed to simulated drift of the ripeners glyphosate and trinexapac-ethyl. For each ripener, the following doses were used: glyphosate (0 (control), 3.6, 7.2, 14.4, 28.8 and 86.4 g a.e ha-1) and trinexapac-ethyl (0, 3.12, 6.25, 12.50, 25 and 75 g a.i ha-1). The effects of these products on plant height, number of leaves, leaf area, stem diameter and dry matter (leaves, stem, flower, root, shoot and total) were evaluated. We also conducted a visual analysis of symptoms of phytotoxicity after exposure. The effects of the ripeners on sunflower plants varied depending on the type of agent used and the dose. Plants treated with glyphosate showed altered growth patterns, indicating high sensitivity of these plants to the herbicide. With increasing doses, glyphosate drift promoted lower growth and development of sunflower plants and negatively affected productivity. Nevertheless, trinexapac-ethyl drift, in the evaluated doses, did not affect sunflower plants.

Since shading often occurs under normal growing conditions in various cropping systems (for example, intercropping, alley cropping), field experiments were carried out to determine the effects of shading on stomatal density, leaf size, leaf dry matter, and leaf lamina thickness in the major tropical root and tuber crops, tannia (Xanthosoma sagittifolium), sweet potato (Ipomoea batatas), yam (Dioscorea esculenta), cassava (Manihot esculenta), and taro (Colocasia esculenta). Shading decreased stomatal density in the lower epidermis of tannia, sweet potato, yam and cassava, and in the upper epidermis also in tannia and sweet potato; the upper epidermis of yam and cassava were devoid of stomata. In contrast to the other species, taro under shade had an increased stomatal density in both the upper and lower epidermis, a finding which was confirmed in subsequent pot experiments. This response of taro was postulated as a possible manifestation of greater shade adaptation by the species.For all the species, shading generally resulted in the production of larger (in terms of surface area) but thinner leaves, with a decreased dry matter concentration. For the two species (yam and cassava) that had stomata only on the lower epidermis, normal sun-grown plants had about twice as many stomata per unit area of lower epidermis than did corresponding plants of the other three species. The agronomic and physiological significance of the findings are discussed.

he prevailing climate of the semiarid region in the northeastern region of Brazil along with inadequate irrigation management, have caused the formation of halomorphic soils, which have hampered agricultural production and environmental sustainability of this region. Therefore, this study aimed to evaluate the emergence and initial growth of the cotton cultivar ‘BRS Topázio’ cultivated in soil with different levels of exchangeable sodium percentage (ESP) and concentrations of organic matter (OM) in a greenhouse from April to June 2014. The experiment was set in a randomized block design in a 5 × 4 factorial scheme, with three replicates, and the treatments consisted of five ESP levels (13.6, 22.4, 30.1, 39.0, and 48.0) and four OM concentrations (0, 5, 10, and 15% based on soil volume). Soils with an ESP ranging from 13.6 to 48.0 did not interfere with the emergence and number of leaves of cotton at 10 days after seeding (DAS). At 44 DAS, in the period preceding the flowering stage, ESPs ranging from 27 to 30 promoted greater plant height, stem diameter, and shoot fresh and dry matter. Increasing OM increased the emergence percentage and emergence speed index and, at 44 DAS, increased plant height, stem diameter, and shoot fresh and dry matter. Increasing OM mitigated the effect of the exchangeable sodium up to an ESP of 30 on the number of leaves, plant height, stem diameter, and leaf area at 10 DAS, and up to mean ESPs of 28.5 and 34.0 for the number of leaves and leaf area, respectively, at 44 DAS.

ABSTRACT Seedling quality is a key factor to achieve success in vegetable production. The present work aimed to evaluate the production of gherkin seedlings in substrate of coconut fiber fertirrigated with different concentrations of nutrients. The experimental design was completely randomized in a 3 × 5 factorial with four replications. The treatments consisted of combinations of three cultivars of gherkin (Do Norte, Liso de Calcutá, e Liso Gibão) with five concentrations of nutrients in the solution (0, 25, 50, 75, and 100%). The nutrient solution, considered standard, matches the recommended solution for melon in hydroponic systems. We evaluated the variables: chlorophyll index, shoot length, number of leaves, stem diameter, main root length, dry weight of leaves, roots, and stem, mass of total dry matter, leaf area, specific leaf area, and leaf area ratio. All variables were affected by the ionic concentration in nutrient solutions. The use of coconut fiber in the production of gherkin seedlings is more efficient with nutrient solutions in concentrations ranging from 75 to 100% of the recommended solution for melon cultivation.

Four orange fleshed sweet potato (OFSP) genotypes viz., CIP 194513.15, CIP 194515.15, CIP 441132 and CIP 440267.2 collected from International Potato Centre (CIP) and four BARI (Bangladesh Agricultural Research Institute) - hybrid orange flesh sweet potato genotypes viz., H16/06, H19/06, H3/07 and H6/07 were evaluated against BARI SP-3 and BARI SP-4 having orange fleshed at Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong for yield and quality. The highest (31.59 t/ha) tuberous root yield was found in CIP 194513.15 which was followed by CIP 440267.2 (30.97 t/ha) and the lowest yield (13.34 t/ha) was obtained in BARI SP 3. The maximum dry matter (29.83%) was obtained in H6/07 while the minimum dry matter (17.61%) was obtained in CIP 441132. Among the tested genotypes the highest (approximately) Vitamin A (919.2 ?g/100 g RE, FW) was recorded in CIP 440267.2, which had red skin and latex absent flesh and the lowest was (approximately) in H6/07 (Vit A 0.0 ?g/100 g RE, FW). The results of the present study indicated that CIP 440267.2 is suitable among the OFSP genotypes for cultivation in Bangladesh on the basis of yield and quality mainly carotinous.

Aims: To assess the field establishment of two tea cultivars under Cocoa Pod Husk (CPH) and Poultry Manure (PM). Study Design: Randomized complete block design arranged in Split-plots (cultivars as main plots and organic amendments as sub-plots) with four replications. Place and Duration of Study: Cocoa Research Institute of Nigeria stations in Ibadan and Owena, Southwest Nigeria between May 2016 and November 2017 (Rainy and dry seasons of 2016; Rainy season of 2017).  Methodology: Milled CPH and cured PM were applied each at the rates of 150 and 300 kg Nha-1 to established C143 and C318 tea cultivars on the field; unfertilized tea cultivars served as control. Data on number of leaves, number of branches, leaf area, plant height and stem diameter were collected on monthly basis; while dry matter was assessed at 15 months after transplanting. The data were analyzed with ANOVA and correlation at α.05. Results: The C143 performed better than C318 and 150 kg Nha-1 of CPH and PM enhanced the vegetative growth and dry matter of tea better than 300 kg Nha-1 in Ibadan and Owena. Cultivar 143 was significantly (P=0.05) better than cultivar 318 in number of leaves, number of branches and stem diameter in Ibadan; and in number of leaves and leaf area in Owena. CPH at 150 kg Nha-1 increased number of leaves, number of branches, leaf area, plant height and total dry matter by 135.11, 88.19, 346.12, 65.33 and 428.11% at Ibadan; and by 349.09, 245.41, 376.89, 80.89 and 231.49% at Owena, compared to control. On the interaction, tea cultivar 143 that received 150 kg Nha-1 CPH produced significantly (P=0.05) higher number of leaves, leaf area and total dry matter at Ibadan and Owena. Leaf area was positively correlated with number of leaves (r=0.87) in Ibadan and stem diameter (r=0.80) in Owena. Conclusion: CPH at 150 kg Nha-1 enhanced the growth and dry matter content of C143 tea established on the field in Ibadan and Owena, and is therefore recommended for tea cultivation in Southwest of Nigeria.
