PROFITABILITY OF RED SWEET PEPPER (CAPSICUM ANNUUM L.) PRODUCTION IN FIELD CULTIVATION

The aim of the study was to assess the profitability of red sweet pepper (Capsicum annuum L.) production in relation to incurred labor and capital inputs in selected horticultural farms. The analyzed group consisted of farms producing sweet pepper in traditional cultivation in the districts of Przysucha and Radom. To determine the correlation between income in the analyzed farms and expenditure, in this study, the multiple Cobb-Douglas production function was applied. Data were generated by implementing the cost accounting method for estimating the feasibility of production and it was analyzed by using project evaluation methods, like the Pay Back Period (PBP), Benefit Cost Ratio (BCR), Net Present Value (NPV) and Internal Rate of Return (IRR). The results of the estimation of Cobb-Douglas production function parameters show that the dominant positive impact on the gross return value was the cost of seedlings, irrigation costs and overhead costs. The conducted analyzes showed that the NPV for the investment is PLN 240,148, with a B/C ratio of 1.78. On the other hand, the PBP, in this case, amounts to 1.45 crop season and the IRR reached a level of 22% annually.The sensitivity analysis carried out showed that the most important factors affecting the profitability of pepper production in field cultivation are product prices, seed costs, fertilizer costs and human labor costs.

The Cost

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

The aim of the study was to assess the relationship between the value of production, labour and capital expenditure in the production of red sweet pepper (Capsicum annuum L.) in selected horticultural farms. The study covered farms involved in the production of sweet peppers in unheated plastic tunnels in the poviat of Przysucha and Radom. The selection of farms was purposeful. The selection was based on the technical solutions used on the farms in the field of construction of plastic tunnels and farm size. The study was carried out in three growing seasons in 2017-2018. The obtained results indicated that the largest share in total costs were the costs of purchasing planting material and fluctuated within 29.5% of total costs. The average production value of red sweet pepper production under covers in tunnels with a wooden structure amounted to 3,116 PLN/240 m2, while in the case of metal structures, this value amounted to 3,449.20 PLN/240 m2. In addition, analysis of the Cobb-Douglas production function showed that the gross profit was affected by general costs, labor costs and costs of purchasing seedlings. The results of this study indicate a need to undertake further research on this topic to formulate recommendations aimed at optimizing paprika production to increase and stabilize income resulting from cultivation activity.

Douglas Production Function

This study was conducted in 2020 to determine the profitability and productivity of organic turmeric production in the Surkhet district of Mid-western Nepal. Face-to-face interviews were conducted with 60 farmers and two focus group discussions were held in four different communities. Turmeric is commonly utilized among Nepalese households in the preparation of curries and is considered one of Nepal’s top five major spice crops. Despite being one of the top five-spice crops, Nepal’s dependency on imported turmeric has been growing every year to meet domestic demand due to the gradual decline in domestic production. The simple descriptive and statistical tools including the Cobb-Douglas production function and benefit-cost analysis were used to analyze the result. The benefit-cost ratio was found to be 1.20, indicating that organic turmeric production was a low profitability sub-sector with a productivity of only 9.06 metric tons per hectare. The Cobb- Douglas production function showed that the cost on seed had a non-significant effect on gross returns and other costs like human labour cost, organic manure cost, ploughing cost, and other costs (agriculture equipment, thread, sack/doko, and rhizome treatment) were found statistically significant. Return to scale was calculated using the Cobb- Douglas production function and it was found to be 0.363, indicating that a 10% increase in the cost of production increases the rate of return by 3.63%, which is a diminishing rate of return. As a result, replacing human labour with agricultural machinery, lowering seed costs, and ensuring appropriate market prices are required to boost the productivity and profitability of organic turmeric production in the research area.

Capsicum Annuum L

Sweet pepper (Capsicum annuum L.) is one of the most important vegetable crops in the world because of the nutritional value of its fruits and its economic importance. Calcium (Ca) improves the quality of sweet pepper fruits, and the application of calcite nanoparticles in agricultural practice has a positive effect on the morphological, physiological, and physicochemical properties of the whole plant. The objectives of this study were to investigate the effect of commercial calcite nanoparticles on yield, chemical, physical, morphological, and multispectral properties of sweet pepper fruits using a combination of conventional and novel image-based nondestructive methods of fruit quality analysis. In the field trial, two sweet pepper cultivars, i.e., Šorokšari and Kurtovska kapija, were treated with commercial calcite nanoparticles (at a concentration of 3% and 5%, calcite-based foliar fertilizer (positive control), and water (negative control) three times during vegetation). Sweet pepper fruits were harvested at the time of technological and physiological maturity. Significant differences were observed between pepper cultivars as well as between harvests times. In general, application of calcite nanoparticles reduced yield and increased fruit firmness. However, different effects of calcite nanoparticles were observed on almost all properties depending on the cultivar. In Šorokšari, calcite nanoparticles and calcite-based foliar fertilizers significantly increased N, P, K, Mg, Fe, Zn, Mn, and Cu at technological maturity, as well as P, Ca, Mg, Fe, Zn, Mn, Cu, and N at physiological maturity. However, in Kurtovska kapija, the treatments increased only Ca at technological maturity and only P at physiological maturity. The effect of treatments on fruit morphological properties was observed only at the second harvest. In Šorokšari, calcite nanoparticles (3% and 5%) increased the fruit length, minimal circle area, and minimal circle radius, and it decreased the fruit width and convex hull compared to the positive and negative controls, respectively. In Kurtovska kapija, calcite nanoparticles increased the fruit width and convex hull compared to the controls. At physiological maturity, lower anthocyanin and chlorophyll indices were found in Kurtovska kapija in both treatments with calcite nanoparticles, while in Šorokšari, the opposite effects were observed.

Pepper Fruit

During the ripening of sweet pepper (Capsicum annuum L.) fruits, in a genetically controlled scenario, enormous metabolic changes occur that affect the physiology of most cell compartments. Peroxisomal catalase gene expression decreases after pepper fruit ripening, while the enzyme is also susceptible to undergo post-translational modifications (nitration, S-nitrosation, and oxidation) promoted by reactive oxygen and nitrogen species (ROS/RNS). Unlike most plant catalases, the pepper fruit enzyme acts as a homodimer, with an atypical native molecular mass of 125 to 135 kDa and an isoelectric point of 7.4, which is higher than that of most plant catalases. These data suggest that ROS/RNS could be essential to modulate the role of catalase in maintaining basic cellular peroxisomal functions during pepper fruit ripening when nitro-oxidative stress occurs. Using catalase from bovine liver as a model and biotin-switch labeling, in-gel trypsin digestion, and nanoliquid chromatography coupled with mass spectrometry, it was found that Cys377 from the bovine enzyme could potentially undergo S-nitrosation. To our knowledge, this is the first report of a cysteine residue from catalase that can be post-translationally modified by S-nitrosation, which makes it especially important to find the target points where the enzyme can be modulated under either physiological or adverse conditions.
