Replacement of mineral fertilizer with organo-mineral fertilizer products made with animal manures is one strategy for reducing the environmental impact of agricultural production. This study evaluated a pelletized organo-mineral fertilizer product with a nutrient analysis of approximately 7-4-4 produced from composted solid poultry, solid dairy and liquid hog manure as a N source for processing potato (Solanum tuberosum L.) production in Atlantic Canada. The availability of N in the organo-mineral fertilizer product was estimated, and tuber yield, size distribution and quality parameters and soil NO3-N content at harvest were compared at similar application rates of N as mineral or organo-mineral fertilizer. Field trials were conducted in 2000 to 2002 to compare different rates of mineral (0–200 kg N ha-1 as NH4NO3) or organo-mineral (0–3 t product ha-1) fertilizer band-applied at planting, followed by split applications of variable rates of mineral fertilizer. Apparent recovery of N from the mineral fertilizer, estimated as the slope of the regression of plant N accumulation against the rate of N applied and expressed as a percentage, was 65, 33 and 78% in 2000, 2001 and 2002, respectively. Apparent recovery of total N in the organo-mineral fertilizer was 6 0 , 26 and 57% in 2000, 2001 and 2002, respectively. Fertilizer N equivalency of the total N in the organo-mineral fertilizer, estimated as the apparent recovery of organo-mineral fertilizer N divided by apparent recovery of mineral fertilizer N and expressed as a percentage, was 92, 79 and 73% in 2000, 2001 and 2002, respectively. Application of equivalent rates of N as mineral or organo-mineral fertilizer at planting generally resulted in comparable values of tuber yield, size distribution and quality parameters and soil NO3-N content at tuber harvest. We recommend application of 1.5 t ha-1 of organo-mineral fertilizer at planting, with additional mineral fertilizer applied as a split application if warranted, as a suitable N source for processing potato production.

Tuber Size Distribution

This study evaluated the effect of rate and timing of N fertilizer application on tuber yield, tuber size distribution and tuber specific gravity of potato (Solanum tuberosum L.) in two sites in a commercial field in 1999–2001. One trial was established at each of the two sites chosen to represent two management zones (MZ) previously delineated by soil electrical conductivity, and differing in soil water availability, as controlled by depth to a clayey substratum. Each trial had 21 treatments including five rates of ammonium nitrate (0–200 kg N ha-1 in 1999; 0–240 kg N ha-1 in 2000 and 2001), each applied according to five application timings (100, 75, 50, 25 or 0% of N applied at planting with the remainder applied at hilling). Increasing N rate increased total and marketable tuber yields in both sites. The N rates required to optimize economic return ranged from 167 to 239 kg ha-1 among years and between sites. Nitrogen fertilizer applied all at planting or all at hilling decreased tuber yields in both sites compared with split N application. The percentage of N rate applied at planting to achieve the maximum marketable tuber yield varied among years from 34 to 61% and allowed a yield increase of 2 to 20%. The proportion of large tubers was higher in the site with a greater depth to the clayey substratum (DMZ site) than in the site with a shallower depth to the clayey substratum (SMZ site). Tuber yield and tuber N uptake were higher in the SMZ site than in the DMZ site when no fertilizer N was applied, and tuber yield was more responsive to fertilizer N rate in the DMZ site than in the SMZ site in one year; however, these differences are not sufficient to justify different fertilizer N management for the two sites. The two sites frequently differed in terms of tuber yield, tuber size and specific gravity, which are important parameters in determining tuber processing quality but the optimal N rate and N timing were similar. These differences may be sufficiently large to justify different potato management practices (e.g., nutrient management, seedpiece spacing) to optimize potato production for the chip processing market.

A study using 15N~labelled fertilizer was initiated in a lysimeter facility to quantify the amount of N assimilated by maize plants and that which remained in the soil at the end of a cropping season. Maize was planted in 0.43 m2 by 1.35 m deep intact Marah clay loam soil cores removed from an improved pasture in mid-October 1983. Two irrigation treatments, flood-impounding water on the soil for up to 72 h, and control-applying enough water to prevent plant stress without ponding, were employed. The crop was harvested in early April 1984 and the amount of fertilizer- and soil-derived N in the plant and remaining in the soil was determined. Grain yields were reduced about 33% by flood irrigation. Although about 30 kg N ha-1 more fertilizer N was lost from the flood-irrigated system, the difference in N recovery between the flood- and control-irrigated soils was not sufficient to account for the reduced grain yield. Flood-irrigated plants were less efficient in transporting fertilizer N to the seed than were control irrigation plants. The data suggest that the reduced seed yield and total N content of maize plants grown under flood irrigation was metabolically controlled rather than being derived from a difference in soil mineral N content compared with control-irrigated soils.

Irrigation is required for profitable commercial potato (Solanum tuberosum L.) production. Excessive or deficit soil water availability during the growing season can have adverse effects on tuber yield, quality, and storability. A field study was conducted during the 2018 and 2019 field and storage seasons in Central Wisconsin, a region in the U.S. with a high volume of potato production, to evaluate the impacts of different irrigation rates on three chipping potato varieties, Hodag, Lamoka, and Snowden. The treatments were implemented during the late-tuber bulking and tuber maturation growth stages, and consisted of irrigation at 125%, 100%, 75%, and 50% of crop evapotranspiration (ET). Irrigation before the treatment period was at 100%ET for all plots. With the industry standard irrigation practice being at 100%ET, other treatments were designated as over-irrigation or deficit irrigation. The impact of these watering rates on tuber yield and quality was evaluated at harvest, and tuber storage quality was assessed by measuring chip fry color and sugar concentrations at 0, 4, and 8 months of storage. It was found that compared to the standard practice, the over-irrigation treatment at 125%ET when tubers reached late bulking resulted in no significant increase in total yield, marketable yield, tuber quality at harvest and during storage, as well as reduced irrigation efficiency (IE) and water-use efficiency (WUE). This treatment also increased nitrate leaching potential in both years. In comparison, deficit irrigation at 75%ET or even 50%ET during the late season had no impact on tuber growth, could increase IE and WUE in one of the two years, and showed reduced drainage. In both years, irrigation rate had no significant effects on hollow heart incidence, tuber specific gravity at harvest, and fry quality during the 8-month storage period. This study suggested that over-irrigation was not beneficial for potato production in Central Wisconsin of the U.S., and deficit irrigation during late tuber bulking and tuber maturation stages could potentially result in more sustainable water use while not penalizing tuber yield, quality and storability of chipping potatoes.

The effects of 15N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L. `Meeker') plants were measured over 2 years. Four nitrogen (N) treatments were applied: singularly at 0, 40, or 80 kg·ha-1 of N in early spring (budbreak), or split with 40 kg·ha-1 of N (unlabeled) applied at budbreak and 40 kg·ha-1 of N (15N-depleted) applied eight weeks later. Plants were sampled six times per year to determine N and 15N content in the plant components throughout the growing season. Soil also was sampled seven times per year to determine inorganic N concentrations within the four treatments as well as in a bare soil plot. There was a tendency for the unfertilized treatment to have the lowest and for the split-N treatment to have the highest yield in both years. N application had no significant effect on plant dry weight or total N content in either year. Dry weight accumulation was 5.5 t·ha-1 and total N accumulation was 88 to 96 kg·ha-1 for aboveground biomass in the fertilized plots in 2001. Of the total N present, averaged over 2 years, 17% was removed in prunings, 12% was lost through primocane leaf senescence, 13% was removed through fruit harvest, 30% remained in the over-wintering plant, and 28% was considered lost or transported to the roots. Peak fertilizer N-uptake occurred by July for the single N applications and by September for the last application in the split-N treatment. This uptake accounted for 36% to 37% (single applications) and 24% (last half of split application) of the 15N applied. Plants receiving the highest single rate of fertilizer took up more fertilizer N while plants receiving the lower rate took up more N from the soil and from storage tissues. By midharvest, fertilizer N was found primarily in the fruit, fruiting laterals, and primocanes (94%) for all fertilized treatments; however, the majority of the fertilizer N applied in the last half of the split application was located in the primocanes (60%). Stored fertilizer N distribution was similar in all fertilized treatments. By the end of the second year, 5% to 12% of the fertilizer acquired in 2001 remained in the fertilized plants. Soil nitrate concentrations increased after fertilization to 78.5 g·m-3, and declined to an average of 35.6 g·m-3 by fruit harvest. Seasonal soil N decline was partially attributed to plant uptake; however, leaching and immobilization into the organic fraction may also have contributed to the decline.

A field experiment was conducted from February to June, 2020 at Bhatkanda, Dadeldhura, Nepal to assess the effectiveness of plastic mulches in potato production. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications comprising of five treatments viz: T1: white plastic mulch (white on black colored), T2: silver plastic mulch (silver on black colored), T3: perforated black plastic mulch, T4: black plastic mulch and T5: control (without mulch). Results revealed that the black plastic mulch significantly increased the rate of emergence while perforated black plastic exhibited highest values of all other studied growth parameters, yield components and quality parameters. The highest marketable tuber yield was obtained in perforated black plastic (6.05 kg/m2) followed by silver plastic (5.62 kg/m2), white plastic (5.46 kg/m2), black plastic (5.14 kg/m2) and lowest marketable tuber yield was obtained in control condition (4.07 kg/m2). Similarly, temperature difference between controlled and mulched condition at 15 cm depth of soil was observed up to 2.8°C with its highest value in black plastic mulch and lowest in control condition. The perforated black plastic mulch was found most economical with maximum value of net return (NRs. 1904.31 thousands/ha) and B: C ratio (5.83). This study concludes that the use of perforated black plastic mulch is most economical with optimum plant growth and yield, producing best quality potatoes under climatic condition of Dadeldhura, Nepal.

Abstract. Nur MSM, Arsa IGBA, Malaipada Y. 2019. The effect of cattle manure and mineral fertilizers on soil chemical properties and tuber yield of purple-fleshed sweet potato in the dryland region of East Nusa Tenggara, Indonesia. Trop Drylands 3: 56-59. A field experiment was carried out to study the effect of combination of cattle manure and mineral fertilizer on the soil chemical properties and yield of purple-fleshed sweet potato in the Integrated Field Laboratory of Archipelagic Dryland Center of Excellence, Universitas Nusa Cendana during November 2017 to March 2018. The experiment was arranged in a Randomized Block Design, with six treatments and four replicates. The assigned treatments were P0 = without manure and without mineral fertilizer, P1 = 100% recommended dosage of manure (20 tons ha-1), P2 = 75% recommended dosage of manure (15 tons ha-1) + 25% recommended dosage of mineral fertilizer (25 kg urea ha-1, 25 kg SP-36 ha-1 and 37.5 kg KCl ha-1), P3 = 50% recommended dosage of manure (10 tons ha-1) + 50% recommended dosage of mineral fertilizer (50 kg urea ha-1, 50 kg SP-36 ha-1 and 75 kg KCl ha-1), P4 = 25% recommended dosage of manure (5 tons ha-1) + 75% recommended dosage of mineral fertilizer (75 kg urea ha-1, 75 kg SP-36 ha-1 and 112.5 kg KCl ha-1), and P5 = 100% recommended dosage of mineral fertilizer (100 kg urea ha-1, 100 kg SP-36 ha-1, 150 kg KCl ha-1). The results showed that P1 and P2 treatments produced the highest contents of organic-C, total-N, available-P, exchangeable-K and soil Cation Exchange Capacity. However, the highest tuber weight was obtained in the treatment P3. These results indicated that the combination of 50% recommended manure dosage (10 tons ha-1) + 50% recommended mineral fertilizer dosage (50 kg urea ha-1, 50 kg SP-36 ha-1 and 75 kg KCl ha-1) could provide a balanced nutrient content in sufficient quantities that meet the sweet potato requirements from the early growth stage to the tuber formation stage, and create soil physical conditions that support the sweet potato tuber development.
