The nutritional quality of the food has become a serious concern in existing agricultural system as the present world aims to enhance only the food production. A field experiment was carried out to study the effect of different fertilizers on growth, vitamin C and calcium content in yield of Capsicum chinense at Regional Agricultural Research and Development Center, Makandura consisting four treatments as without fertilizer (control/ T1), only compost (T2), compost + inorganic fertilizer (T3) and only inorganic fertilizer (T4) with a randomized complete block design (RCBD) replicating four times. Vitamin C content was measured by Indophenol dye redox titration method and calcium content was analyzed by atomic absorption spectrophotometer. Data was analyzed using analysis of variance. The highest growth was recorded in T3 and no significant differences between treatments in growth parameters at 50% flowering stage.The Vitamin C content was highest in treatment with only compost (T2) and the lowest in treatment compost + inorganic fertilizer (T3). The results indicated that yield from organically managed crops contain significantly higher amount of vitamin C (9.24±2.27 mg/100g, p= 0.0274). The highest calcium content was found in T1 (control) (1.1±0.05 %) and a significant difference (p= 0.0296) was observed between T1 (control) and T3 (calcium=0.75±0.12 %). Compost alone can be used to produce food with high amount of vitamin C. Use of inorganic fertilizer alone or integration of compost with inorganic fertilizer was less effective in producing high quality nutritious foods.

Agriculture has been the most contributing sector towards Uganda’s economy. However, its output has always been hampered by declining soil fertility leading to reduced yields, increased agricultural losses, and malnourishment among low-income earners. In Uganda, there is scanty research about the effectiveness of either organic or inorganic fertilizers in crop production. Therefore, there was a need to establish the effectiveness of inorganic fertilizer (N: P: K; 17:17:17) and organic fertilizer (poultry manure/litter) on the growth, and productivity of rhizobia inoculated and non-inoculated bio-fortified NAROBEAN 2 variety, which is rich in iron and zinc, high yielding and drought resistant.  A randomized complete block design experiment was conducted at Mbarara Zonal Agricultural Research and Development Institute (MBAZARDI). Poultry litter was applied at the rate of (10t/ha), N: P: K 17:17:17 at 20.3 kg ha-1, and Rhizobia at 250g per 15 kg of beans. Treatments were; Rhizobia + N: P: K 17:17:17 (M 1), Rhizobia + Poultry litter (M 2), Rhizobia only (M 3), Poultry litter only (M 4), N: P: K 17:17:17 only (M 5) and the control (M 6). Growth parameters included the number of leaves, branches, and shoot height; and productivity parameters included the number of pods produced per plant and economic yield. Statistical analyses were done at 5% level of significance. The growth parameters showed no significant difference (P > 0.05) while the bean grain yield and productivity were significantly different (p < 0.05) under the various treatments. Rhizobia + Poultry litter and N: P: K 17:17:17 only, produced the highest effect on both growth and productivity as compared to other treatments. Application of rhizobia with poultry manure was the best soil treatment for increasing the growth and productivity of NAROBEAN 2. This will increase production, food security, abate malnutrition, and sustainably improve soil quality.

This study aims to determine the concentration of starfruit juice and dragon fruit peel on the quality of jam. The experimental design used was a one-factor Randomized Block Design (RAK) with six treatments and three replications to obtain 18 samples. The treatments were the concentration of starfruit juice and dragon fruit peel extract with P1 (100% : 0%), P2 (85% : 15%), P3 (70% : 15%), P4 (55% : 45%), P5 ( 40% : 60%) and P6 (25% : 75%). Parameters observed were vitamin C levels, antioxidant activity, spread, and color as well as sensory tests (color, aroma, and taste). Data analysis results were tested by analysis of variance at a significance level of 5% using Co-Stat software. If there is a significant difference, then the orthogonal polynomial further test is carried out, while the physical and sensory tests are further tested using the Honest Significant Difference test at a significance level of 5%. The results showed that the concentration of star fruit juice and dragon fruit pulp did not have a different effect on vitamin C levels but had a significantly different effect on antioxidant activity, spread, and color. P6 treatment resulted in the highest antioxidant activity of 77.27%, 12.80 mg of vitamin C content, 10.1 cm of smearing power, and sensory properties that were acceptable to the panelists.

Correction: In the last line of the abstract, the word 'increase' was replaced with the word 'reduced' on 25th November 2015. The correct sentence now reads "The application of PRH, Calsol and Magic Growth significantly reduced rice yield than that obtained with recommended fertilizer dose."AbstractInherent soil fertility and application of exogenous fertilizer generally affect rice yield. Fertilization would be soil fertilization or foliar feeding through leaf area. Plant growth promoting substances also improve plant performance through modulation of its growth and yield. The study was conducted at BRAC Agricultural Research and Development Center (BARDC), Gazipur. The aim of the study was to find out the growth and yield of Boro rice as influenced by plant revitalization hormone (PRH) and liquid fertilizer Calsol and Magic Growth during dry season 2012-13 using randomized complete block design with three replications. Treatment consists of; T1=Recommend fertilizer dose of NPKS and Zn (Control), T2=T1+ recommended PRH, T3=T2 + half of the PRH, T4=Half of doses of T1 + PRH, T5=PRH, T6=Recommended fertilizer dose of NPK with three N top dressed along with Calsol, T7=Recommended fertilizer dose of NPK with 1st and 3rd split of N application and along with three split of Calsol application, T8=Recommended dose of liquid fertilizer Magic Growth. The effect of different treatment combinations of PRH and liquid fertilizer Calsol and Magic Growth showed significant difference (p<0.05) in panicle m-2, unfilled grain panicle-1, total grain panicle-1, and grain yield. However, none of the treatments out yielded the existing fertilizer application method. The application of PRH, Calsol and Magic Growth significantly reduced (corrected on 25th Nov. 2015) rice yield than that obtained with recommended fertilizer dose.Bangladesh Rice j. 2015, 19(1): 33-39

Cassava Varieties

Since there is a variety of performance in cassava varieties for different agroecologies and there was no cassava production before in Ethiopian Somali regional state, Fafen district in particular. Investigation of the performance of higher tuber yielded cassava variety is the main concern for this study. Thus, the objective of this study was to evaluate tuber yield performance of cassava varieties. To do so, four varieties (kello, Qulle, Hawassa-4, and Chichu) were collected from Hawassa Agricultural Research Center and planted in Fafen district where there is arid climatic condition. Thirty-centimeter-long stakes were planted with 1 m × 1 m intra- and inter-row spacing with Randomized Complete Block Design (RCBD). There were four rows, five plants per row and twenty plants per plot. Phenological, growth, and agronomic parameters were analyzed using SAS software; mean differences were compared using LSD at p≤0.05. The result revealed that days to 50% establishment of the stem cuttings of variety “Qulle” were performed within 15.6 days. Among all varieties, Chichu and Hawassa-4 had the highest number of plant stand count, 88.3 and 86.7%, respectively. The highest number of mean multiplication ratio, secondary branches per plant, and mean plant height were obtained with variety “Qulle.” With regards to tuber yield and its components, there was significant difference among understudied cassava varieties. The highest tuber yield (23.93 t/ha) was registered in variety “Hawassa-4” followed by Kello (19.90 t/ha) and Qulle (18.73 t/ha). It implies that variety “Hawassa-4” performed best in the test area and hence recommended in test area.

Background for the Study: Groundnut (Arachis hypogaea L.) is an important crop both in subsistence and commercial agriculture in Ghana. Early leaf spot (Cercospora arachidicola) and late leaf spot (Cercosporidium personata) are major limiting factors to groundnut productivity in Ghana. Aim: The objective of the study was to screen groundnut genotypes for resistance to Early and Late leaf spot diseases. Study Design: The treatments were arranged in a randomized complete block design and replicated three (3) times. Place and Duration of Study: The research was conducted from May to December 2013 at the Savanna Agricultural Research Institute experimental site at Nyankpala in the Northern Region. The site lies between latitude 9°25´141 North and longitude 0°58’142 West and an altitude of 183 m. Methodology: The land was done using a tractor and field divided into plots of 2 m x 5 m with 1 m interval between plots. Sowing was done on 3rd June 2013. One seed was planted per hole at a depth of approximately 4 cm. Early and late leaf spot ratings were recorded at 30, 60 and 90 days after planting, using a ten-point scale. At pod maturity, plants from the middle two rows of each plot were hand-harvested and weights of the above ground foliage and underground pods were oven-dried to obtain dry haulm weight and pod yield respectively. Data collected were subjected to analysis of variance using Genstat statistical package (12th edition). Means were separated using the least significant difference at 5%. Results: The were significant differences (P < .001) among the groundnut genotypes in terms of severity for both early and late leaf spot diseases. F-Mix, NC 7, PC 79-79, F-Mix × SINK 24 and NKATIE-SARI had lowest score for both early and late leaf spot diseases. Among the 21 groundnut genotypes, F-Mix recorded the highest pods yield of 1100kg/ha and haulm weight of 5867 kg/ha followed by NC 7 with total pods yield of 900 kg/ha and haulm weight of 5373 kg/ha. PC 79-79 had a total pods yield of 666.7 kg/ha and haulm weight of 4867kg/ha. The pods yield of F-Mix × SINK 24 was 533.3 kg/ha and haulm weight of 4600 kg/ha. NKATIE-SARI recorded pods yield of 500 kg/ha and haulm weight of 4633 kg/ha. Conclusions: From the study, the genotypes F-Mix, NC 7, PC 79-79, F-Mix × SINK 24 and NKATIE-SARI were found to be resistance to both early and late leaf spot disease whereas Chinese, Doumbala, GM 120, GM 324 and ICGV 86015 were susceptible to both diseases.

Fruits of Capsicum chinense, a native species of Amazon Basin, express high levels of bioactive components such as vitamin C and carotenoids; some of them with pronounced pro-vitamin A activity such as β-carotene, which confers high economic potential to this species. The characterization of C. chinense germplasm helps in its management and conservation. Therefore, this practice is considered crucial for the identification of genotypes with superior characteristics, especially in relation to agronomic aspects and chemical-nutritional characteristics of fruits. This study aimed to characterize 55 C. chinense accessions collected from the Brazilian Amazon in terms of their agronomic and chemical-nutritional descriptors aiming to identify superior genotypes for these traits. The characterization was performed in a completely randomized design with 5 replications in non-heated environment. There was significant difference for all descriptors, confirming the variability among accessions. High heritability estimates for descriptors, such as fruit yield (95.1%) and vitamin C content of fruit (92.4%), was found to be associated with high CVg/CVe ratios of these traits, indicating a favorable condition for the selection of superior genotypes for these characteristics. A considerable part of the accessions expressed averages higher than the checks, notably for the fruit yield and the content of vitamin C. The cluster analysis resulted in the formation of 11 groups, corroborating the high variability of accessions for the agronomic and chemical-nutritional aspects of fruits. The evaluated C. chinense germplasm thus expressed high fruit yield and vitamin C content in the fruits, which makes it a promising source for the selection of superior genotypes.

Low productivity characterizes the production of groundnut among smallholder farmers in Malawi. There is a need to explore options capable of increasing the productivity of the crop sustainably more especially under the changing climate. Against this background, experiments were conducted during the 2016/17 cropping season to investigate the potential to enhance the productivity of groundnut in Malawi through the combined use of inoculants (Graph-Ex and Histick-BASF) and foliar application of nutrients using Allwin fertilizer (legumes). The experiments were established at Bvumbwe and Chitala Agricultural research Stations and were laid in a randomized complete block design (RCBD) replicated four times. Data collected were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance (ANOVA) at a 95% level of confidence. Means were separated by the least significant difference (LSD0.05). In general, foliar application of Allwin fertilizer alone particularly when conducted twice at two and four weeks after emergence produced a positive significant (p<0.05) groundnut grain yield response (97.8-170.8%) above the control. The yield increase is attributable to enhanced growth and development of the groundnut through the foliar supply of nutrients. In general, under the changing climate and amidst other constraints foliar feeding of nutrients using Allwin fertilizer alone particularly when conducted twice can increase significantly groundnut productivity in Malawi.

The field experiment was conducted in the season of 2017-2018 at the Agricultural Research Department-AL-Azafrinih/Baghdad-Iraq. This study aimed to determine the effect of adding the Foliar Fe fertilization (Nano-Fe) and ground fertilization of (N, P) in the growth and production yield of rapes (Brassica napus L.). The experiment included three levels of foliar fertilization (Nano-Fe) that is (0, 5, 10 Kg. ha-1) and one level of ground fertilization (N 100 Kg. ha-1, P 250 Kg. ha-1). The experiment designed according to Randomized Complete Block Design (R.C.B.D) with three replications each parameter. The studied traits were nutrients content (macro-micro) in seeds and soil, the percentage of protein, oil, and carbohydrate. All data were analyzed and used statistically. Results showed a significant difference between Nano-Fe fertilization and nutrient content (N, Mn, K, Ca, Mg, S, and Cu), pH in soil at the level of 10 kg. ha-1, compared to no-fertilization. Moreover, the significant difference between Nano-Fe fertilization, yield (1425.6 kg. ha-1), the percentage of oil (52.16%), protein content in seeds (46.5%), carbohydrate (26.8%), Nutrient content N and P in seeds at the level of 10 kg. ha-1, compared to no-fertilization and the nutrient content (Ca, Mg, Fe) in seeds at levelof5 kg. ha-1, compared to no-fertilization. Current results suggested that Nano-Fe fertilization at the level of 10 kg. ha-1 can be adopted as the best level for rapes (Brassica napus L.) cultivation under semi-arid conditions.
