Effect of NPS and Nitrogen Fertilizer Application Rates for Small Pod Hot Pepper Production (Capsicum annuum L.) Variety at Kellem and West Wollega Zones

Agricultural Reviews, Volume 45 Issue 1: 170-176 (March), 2024

Background: Small pod hot pepper is grown as an annual crop and produced for its fruits. It is one of the most important vegetable crops for fresh consumption, for processing and as a spice (for making stew). The current study aimed to identify the response of different NPS and N fertilizer rates on growth, yield and yield components of small pod hot pepper production in West and Kellem Wollega zones and to determine the optimum and appropriate application rates of NPS and N fertilizer in the study area. Methods: A field experiment was conducted at HaroSabu Agricultural Research Center on Station, Sedi Canqa and Lalo Qile sub sites of Kellem Wollega zone, Western Ethiopia, during the 2020 and 2021 main cropping seasons. Thirteen fertilizer combinations were used as experimental materials. Result: The combined analysis of variance for total yield and other agronomic traits revealed highly significant differences in, plant height, plant canopy length, number of pods per plant and total dry pod yield; whereas days to flowering, days to maturity, number of primary branches per plant, pod length, pod diameter and pod weight revealed non-significant effect. In this experimentation, the combination of 150 kg/ha NPS and 150 kg/ha N (urea) fertilizer rate was found superior in terms of economic yield (marketable yield), and yield component parameters. The marginal rate of return also directed the highest net benefit from the combined fertilizer rate of 150 kg/ha NPS and 150 kg/ha N (urea). Thus the combined fertilizer rate of 150 kg/ha NPS and 150 kg/ha N (urea) is recommended for the yield increment of small pod hot pepper in the studied areas of Western Oromia.

Evaluation of hot pepper (Capsicum annuum L.) cultivars for growth and dry pod yields against different blended fertilizer and nitrogen rates in raya Azebo, Southern Tigray

2021

Hot pepper (Capsicum annum L.) is the most widely cultivated and economically important crop. However, its production and productivities are constrained by different factors in which Cultivar and fertilizer level are the major ones. Thus, the experiment was conducted on two hot pepper cultivars (Melka Shote and Melka Awaze) and six rates NPSZn + urea; to determine the growth and yield response of hot pepper cultivars to different levels NPSZn + urea and interaction effect of both factors. A factorial RCBD (2*6) was used for the experiment and each treatment was replicated thrice. Growth, penological and yield data were collected and and analyzed using SAS version 9.3. ANOVA revealed that plant height, days to first harvest, total leaf area, leaf area index, number of pods plant-1, marketable, unmarketable and total dry pod yield and pod length were significantly (p

African journal of agricultural research

Hot pepper is widely cultivated in different parts of Ethiopia but, its productivity is low due to inadequate nutrient supply, moisture and poor agronomic practices. This experiment was conducted to determine the amount of N and P nutrients required to produce optimum amount of hot pepper marketable yield. Four different rates of DAP and urea fertilizers (25, 50, 75 and 100 kg/ha and control) were used as treatments. There was significant difference (p < 0.05) among treatment means for marketable yield; and highly significant difference (p < 0.01) for branch, fruit and height were observed. Mean comparison for marketable yield was non-significant difference (p > 0.05) between the control, and plots received 25 and 75 kg/ha DAP and urea. In contrast, the amount of marketable yield harvested from an experimental plots received 50 and 100 kg of DAP and urea fertilizers per hectare were significantly different (p < 0.05) from control. Mean comparison revealed marketable yiel...

Effects of eco-green and inorganic nitrogen fertilizer rates on growth and green pod yield of hot pepper (Capsicum annum L.) in Bahir Dar Zuria District of Amhara Region, Ethiopia

Discover sustainability, 2024

Hot pepper (Capsicum annum L.) is one of the most important vegetable crops produced in Ethiopia. However, production and productivity of the crop is far below the world average, which is mostly associated with soil fertility depletions as a result of inappropriate application of fertilizer. Therefore, this field experiment was conducted to evaluate the effects of organic eco-green and inorganic nitrogen fertilizer on the growth and green pod yield of hot pepper during the growing season of 2019/2020. The experiment was designed in factorial combinations of four levels of N (0, 59, 82 and 105 kg ha −1) and four levels of eco-green (0, 75, 125 and 175 L ha −1) which were laid down in Randomized Complete Block Design (RCBD) with three replications. Results revealed that application of N and eco-green (EG) fertilizers very highly significantly (P < 0.001) influenced plant height, numbers of different levels of branches, days to 50% flowering, days to 50% pod setting, days to first harvest, marketable, unmarketable and total green pod yields. Generally, the combination of high levels of nitrogen and EG increased the growth parameters of hot pepper including plant height and number of branches. The highest marketable (17.98 t ha −1) and total green pod yield (18.19 t ha −1) of hot pepper were recorded from the treatment combinations of 59 kg N ha −1 and 125 litter EG ha −1. The same treatment combination had also recorded the highest net benefit (318,516.91 ETB ha −1) with acceptable marginal rate of return (1706%) which can be recommended for economical production of green hot pepper in the study area and areas with similar agro-ecology.

Growth and Productivity of Hot Pepper (Capsicum annuum L.)as Affected by Variety, Nitrogen and Phosphorous at Jinka, Southern Ethiopia

A field experiment was conducted to assess the growth and productivity of hot pepper (Capsicum annuum L.) at Jinka, southern Ethiopia during the 2009 cropping season under rain fed condition using supplementary irrigation. The study consisted of 3 released hot pepper varieties (Mareko Fana, Melka Shote and Melka Zala), 4 levels of nitrogen (0, 50, 100 and 150 kg N ha-1) and 4 levels of phosphorous (0, 46, 92 and 138 kg P 2 O 5 ha-1) in Split-Split plot design with three replications where, variety was assigned as main plot factor nitrogen and phosphorous were arranged as sub and sub-sub plot factors, respectively. Melka zala variety failed to grow after transplanting due to bad season. Data were collected for phenology, growth, fruit yield and yield components. Analysis of variances (ANOVA) revealed that varieties differed significantly (P≤0.05) in number of leaves, stem diameter, fruit length, fruit number per plant, fruit diameter, fruit dry weight, seed number per fruit, total biomass and harvest index. Nitrogen affected positively and significantly (P < 0.05) days to flowering, days to fruiting, days to maturity, plant height, number of leaves, leaf area index, branch number, fruit yield, fruit length, fruit number per plant, fruit diameter, fruit dry weight, seed number per fruit and total biomass but had no significant effect on thousand seed weight and harvest index. Days to flowering, days to fruiting, days to maturity, plant height, number of leaves, leaf area index, stem diameter, fruit yield, fruit length, fruit number per plant, fruit diameter, thousand seed weight, total biomass and harvest index of hot pepper responded positively and significantly (P < 0.05) to increasing phosphorous level; but phosphorous had no significant effect on branch number, fruit dry weight, seed number per fruit. There was no significant interaction between variety, nitrogen and phosphorous levels for all observed parameters except for fruit dry weight and harvest index. In this study, the highest dry fruit yield was achieved using Mareko Fana variety at 150 kg N/ha and phosphorus at 138 kg P 2 O 5 /ha which was by 91% higher than the control. However, according to the partial budget analysis, the highest economic benefits of 74,096 birr/ha was obtained at 50 kg N/ha and 92 kg P 2 O 5 /ha. Therefore, Mareko Fana with application of 50 kg N ha-1 and 92 kg P 2 O 5 ha-1 could be appropriate for hot pepper production in the test area. However, further testing is required in different locations and on different soils.

International Journal of Plant & Soil Science

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
