Sweet potato (Ipomoea batatas L.) is a new crop for soil and climatic conditions of Ukraine, the active implementation of which is hindered by the lack of recommendations on technological aspects of cultivation. One of the important technological measures for growing sweet potatoes is the use of soil mulching, which improves the water regime and regulates the thermal regime of the soil; prevention of weed growth and growth of sweet potato shoots to the soil. Thus, the aim of the research is to determine the efficiency of growing sweet potatoes in the Forest-Steppe of Ukraine by different methods of soil mulching. Field research was carried out on typical low-humus light loamy chernozem on loess loam. It was noted, that when growing sweet potatoes on ridges, the introduction of mulching the soil with black polyethylene film provides more active growth of the vegetative mass throughout the growing season (5.33 shoots/plant with a total length of 252.1 cm), while growing without ridges has a positive effect on plants growth due to the general absence of mulch (2.53 shoots/plant with a total length of 107.8 cm). The use of ridges and mulching the soil with black polyethylene film causes the yield of sweet potato tubers at 34.8 t/ha, while the mulching of the soil with straw, the yield was 18.3–21.9 t/ha, without mulching – 13.0–17, 1 t/ha. Mulching with black polyethylene film ensures the accumulation of vitamin C and starch in sweet potato tubers. When growing the culture on ridges by this method of mulching, the maximum level of vitamin C according to the experiment (4.78 mg/100 g) and starch (11.73 %) was noted. The introduction of mulching and ridge formation involves additional material and labor costs, but helps to reduce weed control and tuber digging costs. When growing sweet potatoes on ridges with mulching with black polyethylene film, the minimum additional labor costs for the formation of a unit of yield (1.95 man-minutes/kg of tubers) were noted, while without mulching and without ridges this figure was 6.76 man-minute/kg

The Cost

Communities in Tumbang Nusa Village, Jabiren Raya District Pulang Pisau Regency began to develop prupuk (Phragmites karka (Retz) Trin ex Steud) as a straw material to replace plastik that is difficult to decompose. This study aims to calculate the cost of production, develop a selling price scenario and conduct a feasibility study on the development of straws from prupuk. Primary data was collected from 20 people involved in making pru[uk straws and supplemented with secondary data from various previous studies and publications.The results of this study indicate that the cost of production of prupuk straws ranges between IDR 374.3 - IDR 408.68 per pcs. The proportion of prupuk straw financing is for the purchase of raw materials (59.72% to 65.14%), labor costs (34.36% to 39.58%) and overhead costs for capital financing (0.6% to 0.7 %). Determination of the selling price is done by adding the cost of goods manufactured to the desired profit (mark up method) with scenario I with a profit rate of 10% (amounting to IDR 389.04 for large packages and IDR 449.54 for small packages) to scenario VI with a level of 60% profit (IDR 565.88 for large packages and IDR 653.88 for small packages). In terms of price, determining the selling price up to scenario VI can still compete with the prices of its competitors, namely bamboo straws. Although the price of the product is competitive, the level of labor productivity is very low. At the break even point condition, the maximum labor income is only IDR 180,062.74. When compared with the UMR District of Pulang Pisau, the income contribution received from making this purun straw is very small (only 6.11%). In order to achieve an income level equivalent to the UMR of Pulang Pisau Regency, a production turnover of 383 pcs per person per day is needed or equal to 7,652 pcs per person per month. In order to improve the quality and quantity of prupuk straws, it is necessary to apply production technology.

Eight genotypes of sweet potato (Ipomoea batatas) were evaluated in four different planting seasons in the central region of Puerto Rico. Planting was in June, September, December and March. Harvesting was at 120 days after planting and data collected included yield, number of non marketable roots, average root weight and percentage of roots affected by the sweet potato weevil (Cylas formicarius var. elengatulus). Genotypes 97-031, 98-040 and 98-022 showed marketable yield (approximately 15,000 kg/ha) when harvested at 120 days after planting and also roots with few lobes, an important trait for fresh market use. Planting season significantly affected yield in the genotypes evaluated. Yields when sweet potato was planted in June, March and September doubled that of the December planting. The planting season significantly affected the percentage of root damage by the sweet potato weevil. Sweet potato planted in March showed significantly less damage than that of the other planting seasons.

ABSTRACT Peanuts are one of the high economic value commodities in the dry land area. This commodity also contributes to the social life of the dry land area. This research has been conducted in Semau Sub-district, Kupang Regency, with the aim to determine the amount of income, break event point (BEP), R / C ratio, efficiency of capital use and factors that affect the income of peanuts farming, with the number of farmer respondents as many as 92 people , simple randomly selected. Data that has been collected by survey, library and interview methods; analyzed quantitatively-descriptive using regression methods. The results showed that the total average income of peanut farming in the study location was IDR 1,739,895 with a total average income of IDR 3,498,261 and a total average cost of IDR 1,758,366. While the break event point average of production is 147 Kg and the break event point price is IDR. 6.509, while for the total average the R / C ratio is 1.99. With factors that affect income are production (X1), seed costs (X2), and labor costs (X3). From the regression results with the Cobb-Douglass function the coefficient of determination (R2) is 0.822 with the meaning that variations in independent variables such as production, seed costs and labor costs explain the dependent variable namely income (Y) of 82.20% and the rest 17.80 % is explained by variables outside of the variables analyzed. From the results of the F test (diversity test) it was found that the factors X1, X2, and X3 had a significant effect on income at ⍺ 1%, then accept H1 at least one of: βi ≠ 0. Whereas the results of the t test (partial test) obtained that factors significant effect on income, namely production (X1) and labor costs (X2), while the cost of seeds (X3) does not significantly affect income.
