Potato (Solanum tuberosum L) is a strategic national food security crop in that can be used as a supplement for carbohydrates. It is the fastest growing staple food crop and source of income for poor smallholder farmers. There is limited documentation on effects of earthing up irish potatoes on yield and yield components in Zimbabwe. A field experiment was conducted in Zaka district of Masvingo province in Zimbabwe during the 2018/19 cropping season. The aim of the study was to investigate the effect of time of earthing up on yield and yield parameters of BP1 potato variety. The treatments consisted of four levels of time of earthing up (no earthing up (control), three, four and five weeks after plant emergence), replicated three times on a Randomized Complete Block Design (RCBD). Results on earthing-up at three weeks recorded significantly (P<0.013) the highest total tuber yield (21.97 t ha-1) which is 10% higher compared to no earthing up which recorded 14.43 t ha-1. Moreover, earthing up at two weeks had the least number of greening tuber yield (3%), 11% pest damaged tuber yield, 6% unmarketable tuber yield and 45% marketable tuber yield. This is in contrast with no earthing up which recorded 91% greening tuber yield, 25.3% on pest damaged tubers, 59% on unmarketable tubers and 10% marketable tuber yield. Based on the results, first earthing up should be done at three weeks after complete plant emergence at the study area under rain fed conditions for the production of potatoes with improved yield and better tuber quality.

N Rates

Meadow soils could supply significant amounts of N for several years and reduce N requirements for the potato (Solanum tuberosum L.). We examined a combination of three crop sequences, three cultivars and six N rates in relation to tuber yield and quality. Superior, Kennebec and Snowden were grown as follows on a Tilly silty loam between 1993 and 1995: (1) 3-yr continuous potato cropping of Superior, (2) 3-yr continuous potato cropping starting with Snowden and followed by 2 yr of Kennebec, and (3) 3-yr sequence of Kennebec, oat (Avena sativa L. 'Marion') and Superior. There were six N treatments (0, 70, 105, 140, 175 and 210 kg N ha−1) and a split application of 140 kg N ha−1 (half at seeding and half before hilling). The seasons were either favorable to growth (1993), relatively wet (1994) or relatively dry (1995). In 1993 and 1994, total yield varied between 37 and 50 t ha−1. In 1995, continuous cropping of Kennebec and Superior produced 28 t ha−1 compared with 37 t ha−1 under crop rotation. The rotation increased total yield of Superior by 34% and graded yield by 42% in 1995. The N requirement was closely related to yield, rather than cultivar. Compared with continuous cropping of Superior, tuber-quality index was highest with the rotation for rhizoctonia (Rhizoctonia solani) (67 vs. 57) and common scab (Streptomyces scabies) (90 vs. 82). The incidence of both diseases decreased when at least 70 kg N ha−1 was applied. For common scab, skin coverages was higher at rates of 0, 175 and 210 kg N ha−1 than at intermediate rates of 70–140 kg N ha−1. Mineral N accumulated in the 0–60-cm layer in the interrow and increased rapidly when N rates exceeded 105 kg N ha−1. After sod breakup an N rate in the range of 70–100 kg N ha−1 and crop rotation with cereals sustained the productivity of the potato during 3 yr while minimizing the environmental impact of mineral N. Key words: Crop rotation, common scab, rhizoctonia, reduced N rates, Solanum tuberosum L.

Nitrogen Fertiliser

Thirteen field trials were conducted on ferrosols and tenosols in Tasmania to assess the response of potatoes (Solanum tuberosum L., cv. Russet Burbank) to basal (up to 250 kg/ha) and topdressed (up to 100 kg/ha) nitrogen fertiliser. Economic yield responses to basal nitrogen were obtained at 9 sites. Topdressing did not increase yield compared with equivalent rates of basal nitrogen, and often failed to compensate for a lack of nitrogen applied at planting. This lack of response may reflect the inability of the potato crop to make use of nitrogen applied during tuber bulking. Nitrogen fertiliser decreased tuber specific gravity at several sites. The effects of nitrogen on misshapen tubers, bruising susceptibility, crisp colour and hollow heart were inconsistent and often of no practical importance. However, at 2 sites, nitrogen fertiliser increased yields of misshapen tubers at the expense of processing tuber yields. At 1 of these sites, nitrogen topdressing decreased the yield of misshapen tubers. Otherwise, topdressing had similar effects on tuber quality to those of basal nitrogen. Growers should fertilise with nitrogen to optimise their yields. Optimum rates were greater in paddocks that had been continuously cropped for more than 10 years (average rate 193 kg/ha), than in those that had been in pasture (average rate 48 kg/ha).

Two field experiments were conducted to investigate the effects of three drip irrigation regimes (G1: 120% crop evapotranspiration (ETc), G2: 100% ETc, and G3: 80% ETc) and four nitrogen (N) source treatments (S0: non-fertilized; S1: urea, S2: ammonium nitrate, and S3: ammonium sulfate on water consumption use, water utilization efficiency, chlorophyll, yield and tubers quality of potato (Solanum tuberosum L.; cv Diamond) under a drip irrigation system during two successive winter seasons (2015/16 and 2016/17)). Nitrogen fertilization was applied at 380 kg ha−1 as standard application for potato in the investigated area. The highest tubers yield was obtained from potato grown with G1 S2 (65.8 Mg ha−1), G1 S3 (63.6 Mg ha−1), G2 S2 (64.1 Mg ha−1), and G2 S3 (62.4 Mg ha−1), while the lowest tubers yield was obtained from potato grown with G3 S0 (10.1 Mg ha−1) and G2S0 (17.4 Mg ha−1). Different treatments of N source resulted in a significant increase for water use efficiency (WUtE) compared with unfertilized treatment. For the interaction effect, the highest WUtE was obtained from potato grown with G3 S2 (18.1 kg m−3), followed by G3 S3 (17.6 kg m−3), while the lowest WUtE was obtained from plants grown with G3S0 (3.0 kg m−3). However, the highest chlorophyll content was obtained from plants grown with G1 and any N source, followed by G2S1-3, while the lowest chlorophyll content was obtained from those grown with G3S0. The highest N, S, protein, and P contents in tubers were obtained from plants grown with G3S3, G3S2, and G2S2, while the highest K content in tubers was obtained from plants grown with G1S1 and G1S2. In concussion, the integrative effects of G1 or G2 with S2 or S3 is recommended for high productivity, while the integrative effects of G3S3 and G3S2 are recommended for high quality tubers.
