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...
The overall objective of this study was to evaluate the effect of different rates of NPK on the growth and yield of two local pepper varieties. The trial was conducted at the Kabala Horticultural Crops Research Centre, Ogoo Farm, Freetown from November 2015 to February, 2016 cropping season. The experiment was laid out in a randomized complete block design with three replications using two varieties of local pepper (Small hot pepper and Gbengeh) grown in the Inland Valley Swamp. Almost all parameters measured showed significant differences for the two local pepper varieties with respect to different rates of fertilizer applied. However, small pepper at 4 weeks after transplanting had no significant difference for canopy spread and weight of nonmarketable fruit. For the gbengeh variety, T3 (120 Kg/ha) recorded the highest 100 fruit weight while in the small pepper T4 (150 Kg/ha) had the highest 100 fruit weight. The Control treatment had the least values for all measured parameters. The rate of fertilizer can influence growth and yield of pepper considerably. However, increasing the rate of fertilizer above 120 Kg/ha showed some negative effects on certain parameters. Best fertilizer regimes observed fall between 90 – 120 Kg/ha.

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. Therefore, it could be recommended for the production of hot pepper crops in the study area and similar agro ecology.

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.

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.

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

A field experiment was conducted on sweet pepper for yield and quality of fruits using different types of organic and inorganic fertilizers at the farm of Patuakhali Science and Technology University. Inorganic and organic fertilizers treatments were tested on California variety of sweet pepper. The fertilization treatments were T1, (Urea +TSP+ MOP): (260+120+124) kg/ha; T2, Cow dung: 9 t/ha; T3, Poultry manure: 7 t/ha; T4, (Urea + cow dung): (195kg +2.5 t/ha); T5,(Urea + poultry manure): (180 kg + 2t/ha); T6, (Urea + cow dung): (130kg + 4.5 t/ha); T7, (Urea + poultry manure): (140kg +3 t/ha);T8, Control: no manure and fertilizer. Randomized complete block design (RCBD) with three replicates were used to conduct this experiment. Physiochemical properties of soil were increasing after harvesting of sweet pepper. Obtained results showed that urea with cow dung (130kg + 4 tons)/ha (T6) increased sweet pepper production. Combined application of urea with cow dung showed significant increase in leaves number per plant (174), Leaf area (48.6cm2), Root/canopy (15.2%), Plant fresh weight (378.5g), No. of fruits/plant (16.6), Fruit length (9.9cm), Fruit diameter (5.8cm), Average green fruit weight (142.1g), Average dry fruit weight (84.6g), yield/replicate (38.5Kg), no. of branching (10.6). Urea with cow dung influenced the total yield per replicate and extended the period of pepper fruit production compared to other treatments.
