Abstract Potato is one of the most important highland crops that highly contribute to food security in different parts of Ethiopia as well as in the world. A major constraint for potato production and productivity includes lack of high yielding varieties, low soil fertility, poor crop management practice, drought, Insect pest, diseases, weeds, poor post-harvest handling techniques, and poor linkages of value chain actors, low dry matter and starch content. The major objectives of this project are to introduce best-performed genotypes with good pest resistance, improve potato cultivation techniques with appropriate agronomic practices, to identify and manage major pests of potato and their effects on yield loss, analyses potato value chain actors and production economics, evaluate post-harvest handling of potato. The project will be carried out using different experimental designs (Randomized Complete Block Design, split plot, lattice arrangement, single plot), sampling methods (random and systematic sampling techniques), both qualitative and quantitative data will be collected and analysed using different statistical software packages (SAS, SPSS, Genstat, PBTools).

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

Potato production is adversely affected by aphid infestation across the globe. Understanding the mechanism of host plant defense against aphids under drought stress is paramount for insect pest management. This study was conducted to examine the cross-talk of phytohormones in potato glycoalkaloids’ defense against green peach aphids under greenhouse conditions. A 3 × 2 × 2 factorial experiment comprising three potato cultivars (Qingshu 9, Longshu 3, and Atlantic) and two levels each of water availability and aphid infestation was conducted. The results show that under drought stress, green peach aphids thrive well on host plants, which contain a relatively high water content. The resistant cultivar DXY, which exhibited a higher level of phytohormones, also demonstrated higher α-chaconine and α-solanine contents in both leaf and root, under drought and aphid stress. Conversely, the susceptible cultivar QS9, which exhibited a lower level of phytohormones, also demonstrated low α-chaconine and α-solanine contents in both leaf and root, under drought and aphid stress. The DXY cultivar, which possessed high resistant traits such as α-chaconine and α-solanine, can be used in areas where green peach aphid infestation is a major setback.

In Uganda, agricultural commercialization has been promoted to reduce poverty and improve household food security. South-western Uganda, the major producer of potato, has been considered the food basket of the country but it has one of the highest prevalence rates of stunting in children under 5. This study considered potato enterprise as a key pathway for enhancing household food and nutrition security because it has become a major income source and staple in the diets of many households in the area and most urban areas in the country. The objective was to determine factors that influence farm household nutrition and food security outcomes. Through a survey, data were collected from 434 randomly selected potato farmer households. Descriptive and econometric methods were used in data analysis. Results show that household dietary diversity score was low (3.2) for most (57%) of the households. Only 38% were food secure. The main factors enhancing household nutrition outcomes were size of land, livestock units owned, proportion of household income spent on food, and education of household head, while farmer’s experience in potato production had a negative effect. The size of land owned, crop diversification, income from potato, age and education of household head, and a famer being male enhanced household food security outcomes. The study recommends promoting improved production practices to maximize land productivity, integration of livestock in potato production, and training women and men in household food and nutrition and related use of income.

<p>Potato (<em>Solanum tuberosum </em>L.), is one of the important crops grown in the world which is important as food and nutritional security option at the global level. The experiment was laid out as randomized complete block design in three replications with six nutrition treatments consisted of control, NPK, Mog bio-fertilizer, Nano-Ca, Nano-Zn+B and Nano-Com. The treatment-by-trait (TT) biplot analysis was applied to data to examine its usefulness in visualizing relationships among trait as well as treatments and showed that the first two principal components accounted 80% of total variation. Tuber yield, mean tuber diameter, mean tuber weight, tuber weight per plant, starch content of initial fresh, number of tubers per plant, number of leaves and dry matter content were in the same sector, with Nano-Com fertilizer treatment as the best treatment. Based on ideal entry biplot, the Nano-Com treatment is closest to the position of an ideal treatment and it is ranked the highest in term of morphological performance. Also, the best fertilizer treatment for obtaining of high tuber yield could be found as Nano-Com treatment following Nano-Zn+B treatment. The studied nanofertilizers showed a good potential compared to the commercial bulk and bio fertilizers.</p>

Potato (Solanum tuberosum L.) is a versatile crop and a source of inexpensive energy in the human diet in many countries. It can be used as fresh products and commercially processed foods such as French fries and chips. Potato varieties development research previously conducted in Ethiopia related to processing quality were limited in their scope of quality parameters. This experiment was conducted at Holetta Agricultural Research Centre, Ethiopia during the main crop season of 2017. Twenty-four potato genotypes were evaluated for 23 quantitative and six qualitative traits in randomized complete block design with three replications to determining the nature and magnitude of common genetic diversity and to screen out genetically diverse parents by using cluster and principal component analysis. The first eight principal components accounted for 90.26% of the observed variations among 24 potato genotypes. The first three PC accounted for 60.43% of the variation. The genetic distances among the 24 potato genotypes ranged from 3.40 to 11.80 and the genotypes were grouped into eight clusters based on quantitative and qualitative traits. Cluster II consisted of 25%, Cluster IV, I, III contained 20.83%, 16.67% and 12.5% of genotypes, respectively, while Cluster VI, VII and VIII each consisted of one genotype. In conclusion, genotypes grouped under Cluster II and VIII worth further evaluation to obtain genotypes with highest total tuber yield, the specific gravity of tuber, dry matter content, total starch content, acceptable tuber physical and frying quality with other desirable traits.

Among food crops in terms of consumption, potato ranks fourth, most important and valuable crop worldwide in terms of production and area harvested after maize, wheat and rice. In the coming years, potato production must keep pace with global population expansion nutritiously and sustainably which can partially be achieved by reducing the yield losses caused by the destructive pest and disease activities to the crop. The challenge of 70–80% total microbial crop yield loss posed by pathogens must be addressed for sustainable potato production in order to properly alleviate the global starvation problem. Potato as a food security crop can help to achieve the four food security requirements: food availability, quality, accessibility and stability. Health benefits of potato have shown the presence of phytochemicals as well as resistant starch which serve as anticancer and antidiabetic. The role of potato in the global food security should not be over emphasized, hence in this chapter we want to give an overview on the global hunger and food security at present, and the role played by potato as a food security crop. In addition, potato yield losses caused by pests and diseases especially phytopathogens, their etiology and the role of crop protection in sustainable potato production to alleviate global starvation problem will be discussed.

The highland of Bale is known with potato production, but post harvest quality of the crop is not emphasized yet. Therefore, this study was conducted to evaluate six potato varieties with the objective of assessing the effect of varieties and growing on tuber nutritional and process quality of potato grown in Sinana and Dinsho highlands of Bale. The experiment was laid out in randomized complete block design with three replications. The varieties showed highly significant (P<0.05) differences for all the parameters studied across the locations. The highest specific gravity, dry matter content and starch content (1.107, 26.61 and 19.19) were recorded from Dinsho location for Guddene variety while the lowest specific gravity, dry matter content and starch content (1.084, 19.41 and 14.61) were recorded from Sinana location for Ararsa variety. Most of the varieties were recorded as the highest values of specific gravity, dry matter and starch content at Dinsho indicating that it is an ideal location for potato production to be used for processing while Sinana is suitable for the production for home consumption. However, it is necessary to evaluate these varieties for a number of seasons and locations to recommend with high post harvest quality parameters required by the processors.Int. J. Agril. Res.

This study aimed to evaluate the growth and yield of two potato genotypes (S) due to three sources of nitrogen (G) fertilizer on medium plains. The study was arranged in a two-factor, randomized block design factorial and was repeated three times. The first factor is the source of N fertilizer, consisting of three levels: S1 = ZA ((NH4)2SO4), S2 = urea (CO(NH2)2), and S3 = ammonium nitrate (NH4NO3). The second factor was potato genotype, consisting of two levels G1 = MS 13 genotype and G2 = At 4 genotype. The data obtained were analyzed by F test at 5% level (ANOVA) to determine the effect of treatment and further LSD test was carried out to determine differences between treatments, and multiple regression analysis to determine the most influential factors on potato tuber starch content. The results showed that the highest starch content was obtained by the At 4 genotype of 18,50% and was suitable for medium plains. While the starch content of the MS 13 genotype was 17,53%. For fertilizing nitrogen sources, it is recommended to use ammonium nitrate, because it obtains the highest yield of 27,30 tons ha-1 from other nitrogen fertilizer sources.

The eastern sub-Himalayan plain of India is a popular potato growing belt in which vast scope exists to introduce processing grade cultivars. The selection and introduction of a better quality processing grade cultivar in this region may pave the way for the processing industries. Keeping these in the backdrop, this study was conducted at Instructional Farm of Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India under eastern sub-Himalayan plains during winter seasons of 2016–17 and 2017–18 in which seven processing type potato cultivars (Kufri Chipsona-1, Kufri Chipsona-3, Kufri Chipsona-4, Kufri Frysona, Kufri Himsona, Kufri Surya and Kufri Chandramukhi) were evaluated in terms of different quality parameters pre-requisite for chips processing viz., dry matter content, specific gravity, starch content, chips colour score, crispiness and hardness of chips through randomised complete block design (RCBD). The study revealed wide variation in all quality parameters amongst the cultivars. Cultivar ‘Kufri Frysona’ showed the highest specific gravity (1.121) as well as dry matter content (23.35%) followed by ‘Kufri Chipsona-3’. The cultivar ‘Kufri Frysona’ showed the highest starch content (28.52%) too. Chips prepared from ‘Kufri Chipsona-1’ were recorded to be crispier with a relatively lower value of deformation before the first break and less hardness value. All processing type potato cultivar reflected the chips colour score <3 (evaluated, based on 1–10 scale, 10 being the darkest and least desirable) though ‘Kufri Frysona’ had the lowest chips colour score (1.50) signifying its superiority for the region. ‘Kufri Frysona’ cultivation could be recommended in this agro-climatic region particularly for chips manufacturing potato industries.
