Important Disease

Potato (Solanum tuberosum L.) has various biotic constraints in its production due to pest attack. Among these, common scab caused by streptomyces scabies is an important disease in potato which causes economic loss with respect to plant yield and quality of tubers. The present study was conducted to determine the pathogenicity, pathogenic variation, characterization of morphological, physiological and biochemical aspects of Streptomyces associated with potato tubers grown in Rawalpindi district. Severity data and pathogenic variation of disease was studied by using different isolation and characterization techniques.

This investigation was carried out during the two summer seasons of 2015 and2016 in sandy soil on potato culitvar "Sante" to study the effect of using 100%compost (15 t/fed.) and 50% compost + nitrogen fixing bacteria (Azotobacter, andPseudomonas alone or together) on potato yield and quality as compared to theconventional mineral fertilization (120-75-150 kg/fed. NPK + 5 toncompost/fed.(control)). No significant differences in tubers yield/fed. were detectedbetween mineral fertilization (control) and using 100% compost (15t/fed).However, control treatment significantly produced a high yield per feddan,more than using 50% compost + any biofertilizer treatment.Using composttreatment at 15 t/fed.execeed all biofertilizer treatments in marketable yield in bothseasons, but without significant differences as compared with mineral fertilization(control).No significant differences in tuber dray matter and content of starch intuber were found between using compost treatment at 15 ton/fed. and mineralfertilization treatment (control)in both seasons. Nevertheless, application of 50%compost+ 4 applications of Azotobacter and Pseudomonas had the highest tuberconcentrations of starch and nitrogen with significant differences as compared withthe mineral fertilization.Using50% compost + 4 applications of Azotobacter orPseudomonas or both (Azotobacter + Pseudomonas )and application of 100%compost caused producing potato tubers with the lowest concentration of nitratewith significant differences as compared with the mineral fertilization. Nosignificant differences were detected between mineral and organic fertilizersconcerning P and K concentrations in tubers.

SUMMARYThe effects of planting potato tubers on four different sides of two ridge orientations was investigated. Soil temperature was coolest on the northern side, followed by the western, eastern and southern sides. Fifty percent emergence took place in 24, 42 and 49 days for tubers planted on the northern, western and eastern sides, respectively. Only 22% of tubers planted on the southern side emerged. The best yield and quality was obtained by planting on the northern side, followed successively by the eastern, western and southern sides of the ridge.

As a result of the conducted research, it was found that in the conditions of the non-Chernozem zone, potato varieties of Madeira and Morning on sod-podzolic medium-loamy medium-cultivated soil are able to form a yield of tubers up to 33 t / ha. The influence of the sideral precursor on the yield and quality of potato tubers is scientifically justified.

В статье приведены результаты исследований по изучению влияния минеральных удобрений и куриного помета на продуктивность клубней картофеля отечественной и зарубежной селекции. В исследованиях, проведенных в 2017-2019 гг. на черноземе выщелоченном в условиях Пензенской области, установлено, что при внесении куриного помета и минеральных удобрений повышается урожайность и качество клубней, что непосредственно связано с обеспеченностью растений питательными веществами. Применение куриного помета в дозе 2 т/га позволило повысить общую урожайность клубней исследуемых сортов картофеля на 22,6-29,5, товарных клубней на 24,3-35,5 по сравнению с вариантом без удобрений. Наибольшую урожайность наблюдали на вариантах с совместным применением мочевины в дозе N30 и сульфата калия в дозе К60 и на вариантах с совместным применением аммофоски в дозе N30Р30К30 и сульфата калия в дозе К30. Применение умеренных доз минеральных удобрений и куриного помета в дозе 2 т/га увеличивает не только урожайность клубней картофеля, но и содержание в клубнях сухого вещества, крахмала и нитратов, не превышающих значения ПДК. Совместное применение азотно-калийных и азотно-фосфорно-калийных удобрений с добавлением сульфата калия в дозах К60 и К30 позволяют улучшить качественные показатели клубней по всем изучаемым сортам.The article presents the results of studies on the influence of mineral fertilizers and chicken manure on the productivity of potato tubers of domestic and foreign selection. In the studies conducted in 2017-2019 on leached chernozem under the conditions of the Penza region, it was found that when chicken manure and mineral fertilizers are applied, the yield and quality of tubers increases, which is directly related to the supply of plants with nutrients. The use of chicken manure at a dose of 2 t/ha allowed to increase the total yield of tubers of the studied varieties of potatoes by 22.6-29.5, marketable tubers by 24.3-35.5 compared with the variant without fertilizers. The highest yields were observed in variants with the combined use of carbamide in a dose of N30 and potassium sulfate at a dose K60 and in variants with a combined use of ammophos at a dose N30P30K30 and potassium sulfate at a dose K30.The use of moderate doses of mineral fertilizers and chicken manure at a dose of 2 t/ha increases not only the productivity of potato tubers, but also the content of dry matter, starch and nitrates in the tubers, not exceeding the MAC value. The combined use of nitrogen-potassium and nitrogen-phosphorus-potassium fertilizers with the addition of potassium sulfate at doses of K60 and K30 can improve the quality indicators of tubers for all studied varieties.

The different potato planting dates in southern Brazil have different climatic factors that affect the yield and quality of the tubers produced. The objective of this work was to test the effect of planting date and potato cultivars on the postharvest greening of tubers. The treatments consisted of three planting dates (October, December, and February) and three potato cultivars (Agata, BRS Clara, and BRS F63 Camila). It was observed that the tubers harvested in February were less susceptible to greening, probably due to the higher physiological maturity of the tubers produced in this planting date. Tubers of cv. BRS Clara had lower greening than the tubers of the other cultivars. In addition to the light conditions, the cultivar and storage air temperature are also important factors that affect greening rates. Care must be taken with these factors to avoid losses of tubers by greening.
