Hot Pepper is an important food and cash crop in eastern Ethiopia including Daro labu and Boke Districts of West Hararghe Zone. A field experiment was conducted in Daro labu and Boke Districts, under rainfed during 2016-2017 cropping season, with the objectives of to determine the influence of NP fertilizers rates and method of planting on the yield and yield components of hot pepper and to estimate the cost-benefit of application fertilize rates and planting method in hot pepper production. Mareko fana variety, which is the dominant hot pepper variety produced in the area was used as planting material for the study, The treatments consisted of five combined rates of Nitrogen and phosphorus (0/0, 41/46, 61/69, 82/92 and 102/115 kg level of N/P 2 O 5 ha-1) and three methods of planting (broadcasting, drilling and transplanting method) were used. The experiment was laid out as a randomized complete block design in a 5 x 3 factorial arrangement and replicated three times. From the combined analysis of variance over the location, the result revealed that the two main factors fertilizer rates and planting method had a significant effect on all traits, except that fertilizer and planting method had a non-significant effect on fruit diameter, from interaction effect of fertilizer rates and planting methods, the highest mean of plant height (64.24cm), canopy diameter (44.15cm) and fruit number (26.70) per plant were obtained from 102/115kg N/P ha-1 in combined with drilling planting method. The highest fruit length (9.33cm), diameter (3.92), weight (2.82 gm), marketable (2.05t/ha) and total yield (2.26 t/ha) were recorded from plots that received 102/115 kg N/P ha-1 fertilizers combined with drilling planting method, while the lowest dry pod yield (0.55t/ha) was obtained from plot received control 0/0 kg NP ha-1 combined with transplanting method. While the highest unmarketable fruit yield (0.42 t/ha) was recorded from control (0/0) with the broadcasting method. Moreover, Partial budget analysis result has shown that application of 102/115 kg N/P ha-1 fertilizer rate with combined with drilling planting method was found to be economically viable with net income 71572.25 of Birr ha-1 with 265.28% marginal rate of return was obtained from the application of 102/115 kg N/P ha-1 fertilizer rate combined with drilling sowing method.

Hot pepper production is constrained by declining soil fertility and poor management practices in Assosa area, western Ethiopia. An experiment was conducted at Assosa Agricultural Research Center, during 2017/18 cropping season to evaluate different rates of blended fertilizers on agronomic performance and pod yield, and economic profitability of hot pepper production. The treatments included were: control, recommended NP, three rates for each NPSB and NPSBZn (100, 150, 200 kg ha-1) arranged in a randomized complete block design, with three replications. In the blends since N proportion was low, supplementary N was applied from Urea to optimize N needs of the crop. The result of the study revealed that the growth parameters (plant height and number of branches), yield components (number of pod per plant, pod length and width) and marketable pod yield were significantly (p<0.05) affected by fertilizer rates and types. The marketable dry pod yield was improved by 134.7% with the application of 150 kg NPSBZn + 44 kg ha-1 N as compared to the control. Moreover, this treatment generated the highest net benefit of Original Research Article

1 SUMMARY To determine the effect of organominerals and inorganic fertilizers application on the optimum yield and nutrient composition of pepper ( Capsicum frutescence ) so as to form an effective basis for selection of fertilizer and growth improvement strategy. Pepper seedlings were subjected to two levels of nitrogen, phosphorus and potassium 15-1515 fertilizer (NPK) (0 and 250 kg. ha -1 ), , five levels of organomineral fertilizers (OMF) (0, 2, 3, 4 and 5 t. ha -1 ) and their various combinations. These were assigned randomly into three replicates and arranged in a randomized complete block design fitted into a factorial experiment. Pepper growth, fruit yield and quality attributes were assessed and subjected to Analysis of Variance. The growth parameters such as plant height and number of leaves showed increasing response to all the treatments as the rates increased. Also the yield components increased as the rates increased from 0 to 4 t OMF ha -1 and thereafter a reduction i...

A field experiment was conducted to investigate the effect of inorganic nitrogen and potassium fertilizers on the yield and physical quality parameters of hot pepper (Capsicum annum L.) in South-eastern high land of Ethiopia using supplemental irrigation in 2009/2010 production season. The treatments consisted of four levels of nitrogen (0, 50, 100 and 150 kg N hanitrogen) and three levels of potassium (0, 150 and 300 kg K 2 O ha -1 ). The experiment was laid out as a randomized complete block design (RCBD) in a factorial arrangement and with three replications. It was found that nitrogen had significant main effect on yield and quality components of the crop. Nitrogen at 100 kg ha -1 resulted in the highest total dried pod yield (3.1 t ha -1 ), marketable yield (2.7 t ha -1 ) pod length (10.6 cm) and pod width (3.4 cm).The highest unmarketable yield (0.63 t ha -1 ) was obtained at the highest level of N application (150 kg N ha -1 ). Potassium did not affect any of the parameters measured. In addition, at all levels of potassium supply, including the control treatment, the concentration of the nutrient in the leaf tissue was in the adequate range indicating that potassium supply was not limiting in the soil for uptake and growth of the plant. Furthermore, nitrogen and potassium did not interact to influence any of the yield and quality parameters measured. Application of nitrogen at the rate of 100 kg ha -1 resulted in the production of optimum dried pod yield and also improved the physical quality attributes of hot pepper.

The objective of this study was to improve the growth and yield of long cayenne pepper using 10 organic fertilizers. Organic fertilizers including tithonia compost (TC), poultry manure from a battery cage (PMB), poultry manure from dip-litter (PMD), pacesetter organic fertilizer (POF), sunshine organic fertilizer (SOF), ayeye organic fertilizer (AOF), brewery waste (BW), cow dung (CD), oil palm bunch ash (OPBA), cocoa pod husk (CPH) were collected at some specific locations in Oyo, Osun and Ondo States of Nigeria. The experiment was a 2×11 factorial experiment fitted into a randomized complete block design consisting of 10 organic fertilizers and the control at two locations (Ibadan and Ogbomoso) in 2008. The dosage of 130 kg N ha-1 of each of organic fertilizer was applied one week before transplanting. Six-week-old pepper seedlings were transplanted into a plot of 3m×2m (6m 2) with one seedling per hill. Growth and yield data collected were subjected to analysis of variance (ANOVA) and the least significant difference (LSD) at p<0.05 was used to compare the means. The results of the experiment reveal that the overall macronutrient content of the ten evaluated organic fertilizer sources was presented in the following order: SOF>OPBA=CPH>AOF>TC>POF>PMB=CD>BW>PMD. All the organic fertilizers more significantly enhanced the growth and yield of pepper than the control. The best three organic fertilizers at both locations in terms of fruit length were TC=SOF=PM. Fruit size at Ogbomoso was relatively bigger than that of Ibadan. The total fruit yield was highest under TC, SOF, PM and PMD at both locations. In conclusion, variations existed in the nutrient composition of the organic fertilizer. Meanwhile, TC, PMB, PMD and SOF were significantly similar in their ability to improve pepper yield. Moreover, PMB, TC and SOF significantly enhanced the vegetative growth of pepper.
The chilli pepper (Capsicum chinense Jacq.) is a highly prized and widely consumed vegetable throughout the world. In Burkina Faso, its production remains marginal, despite its numerous agronomic and economic potential. The aim of the study was to assess the effect of organic, mineral and organo-mineral fertilization on the agronomic performance of chilli pepper. A trial was conducted in a completely randomized block design with four treatments (Compost = 16 t/ha Compost; Compost+NPK = 8 t/ha +100 kg/ha; NPK = 200 kg/ha; and Absolute control) and four replications. Morphological, physiological, phytosanitary and harvesting parameters were assessed. The results showed that the treatments did not induce any significant difference in the physiological parameters. The NPK significantly reduced the number of harvested plants by 87 % compared with the Absolute control (p ≤ 0.01). NPK treatment significantly (p < 0.05) improved plant collar diameter by 41 %; number of fruits harvested by 73 %; number of yellow fruits harvested by 74 %; number of fruits harvested per number of plants harvested by 57 %; fruit length by 25 %; and fruit yield by 70 % of chilli pepper compared with the Absolute control. The Compost treatment significantly increased the number of perforated fruits by 79 % compared with the control. Thus, compared with other treatments, mineral fertilization (200 kg/ha of NPK) was more effective of the best agronomic performance of chilli pepper.

Field experiment was conducted within the Teaching and Research Farm of the Faculty ofAgriculture, Akwa Ibom State University, Obio Akpa Campus in Oruk Anam Local GovernmentArea in two locations. The objective was to determine the effects of rates of organo-mineral fertilizer (OMF) on soil properties and on the performance of chilli pepper (Capsicum annum L.). Four rates (0, 2, 4 and 6 t/ha) of OMF was laid out on a randomized complete block design with four replicates. The soil used for the experiment was loamy sand with a pH of 5.3. Results obtained showed that the application of OMF at all rates significantly improved the soil properties (total nitrogen, organic carbon, available phosphorus, exchangeable Ca, Mg, ECEC, base saturation) relative to control. Chilli pepper responded positively to the application of OMF at all rates but superior increases in fruit number, fruit length, fruit width, fruit weight and fruit yield were obtained from plants treated with 4 t/ha of OMF. The highest fruit yield (1.92 t/ha) was obtained from the 4t/ha of OMF closely followed by the 6 t/ha (1.82 t/ha), then the 2 t/ha treated soil (1.35 t/ha) while the least value was obtained from the control (0.31 t/ha).Relative yield increase of treated soils over the control was 335.5%, 519.4% and 487.1% for 2, 4 and 6 t/ha rates of OMF, respectively. Based on the findings from this study, addition of OMFespecially at4t/ha is appropriate for sustainable production of chilli pepper in Obio Akpa.

NPK fertilizer was applied either at 1,2,3 or 4 weeks after transplanting (WAT) to determine its effect on the following performance variables: plant height, stem girth, days to flower, number of fruits and fruit weight per plant. NPK fertilizer application within the first three weeks after transplanting resulted to taller plant than the 4WAT application. The result of the study also showed that Application of NPK fertilizer within the first two weeks after transplanting produced higher number of leaves, early flowering time and subsequently produced the highest fruit yield of pepper. It is concluded that early application of fertilizer to pepper after transplanting will result to fast and improved growth as well as increase yield of sweet pepper.
