A field experiment was carried out at Breeder seed Production Centre (BSPC), Debiganj, Panchagarh during the Rabi season of 2016-2017 to study the effect of five levels of sulphur application on yield and quality attributes of three potato varieties. The main objective of the experiment was to determine the effect of sulphur on the yield and quality of potato varieties. There were five treatments comprising different levels of sulphur such as T1 (control-no sulphur), T2 (75% RDS), T3 (100% RDS), T4 (125% RDS) and T5 (150% RDS). Three BARI released potato variety; BARI Alu 36 (4.26 R), BARI Alu 40 (4.45W) and BARI Alu 25 (Asterix) were used in this experiment. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The tuber yield and yield contributing characters were significantly influenced by the application of sulphur. Maximum tuber yield (39.28 t/ha) was recorded in BARI Alu 40 (4.45 w). Highest dry matter content, specific gravity and starch content were found in BARI Alu 40 (4.45 w), which was followed by BARI Alu 36 (4.26 R) in case of specific gravity and starch content. Sulphur application in potato varieties showed significant influence on tuber yield of potato. This parameter increased with increasing dose of sulphur up to 100% RDS. Thereafter, further increase in sulphur did not showed any remarkable influence. Besides, sulphur application in potato varieties showed significant influence on tuber quality of potato. The maximum dry matter yield and starch yield were recorded in the treatment T3, which was followed by all other  treatments except T1. The minimum dry matter yield and starch yield were recorded in the treatment T1. Combined effect showed insignificant influences between varieties and sulphur levels. BARI Alu 40 (4.45 w) was found superior over other varieties in terms of yield and quality attributes. Treatment T3 (100% RDS) was found superior over other treatments in terms of yield.

The effect of microfertilizer «Agro-Master» on the yield and quality of early and medium early of potato tubers varieties was studied, carried out at the experimental field of North Caucasus Research Institute of Mountain and Foothill Agriculture - branch of the VSC of RAS in the forest-steppe zone of Republic of North Ossetia-Alania on grass rotation in the period from 2017 to 2019 yy. The experimental data indicate that the use of microfertilizer «Agro-Master» in a specific soil and climate zone is a promising technique that can improve the productivity and quality of potato tubers in the field. The data of our studies on leached chernozems showed no clear differences in the timing of the onset of the development phases of potatoes. The intensity and speed of emergence of seedlings to a greater extent depends on weather conditions and varietal characteristics. It was found that when spraying potatoes with microfertilizer «Agro-Master» in different doses, the process of dying of tops is slowed down in comparison with the control options. So, in the Zukofsky early variety, the top-off phase begins 7-8 days earlier than the Red Scarlett variety and 10-11 days of the Predgorny variety of local selection. The maximum yield increase was observed when processing of the microfertilizer «Agro-Master» at a dose of 2 kg/he on the pre-mountain local breeding grade – 27,5 tons per hectare, while the increase in yield to control was 5,0 tons per hectare, for varieties of Zukofsky early and Red Scarlett – 5,0 and 4,7 tons per hectare respectively. The highest dry matter content was on the experimental version (dose 2 kg / ha) for the Predgorny variety – 26,6 %, the Zukofsky early and Red Scarlett varieties – 25,9 and 23,8 %, that accordingly is more than control on 3; 2 and 3 %. The starch content in the studied potato tubers in the experimental varieties was diverse. The maximum starch content in potato tubers was obtained using the variant treated with Agro-Master at a dose of 2 kg/he for Predgorny variety (16,0 %), which is explained by the favorable influence of microfertilizer «Agro-Master» and the manifestation of varietal characteristics.

The Impact

Gaining high yield of potato is very crucial for farmer and quality also has a great impact on their production. Beside the quality and yield using the amount of irrigation also important to reduce water lose. The tuber yield and quality of potato (Solanum tuberosum L.) is impacted by irrigated water. This study was carried out in two respectively season (2017 and 2018) in Halabja province of Kurdistan regional of Iraq to evaluate the impact of irrigation interval on quality and tuber yield in potato cultivars. In this study there are  four irrigation intervals (3,5,7 and 9 days) used by furrow irrigation method which subjected in complete randomized design (CRD) with three replications. The potato tuber production in 3 day interval showed highest percentage also protein and starch content was recorded highest in both year of cultivation, but the abscisic acid was affected by more irrigation which in 3 day interval irrigation the rate was less than other. Also in 5 day interval irrigation the rate was acceptable because there is no significant difference in terms of tuber yield, protein and starch content if compare with 3 day interval irrigation in particular for those area faced restricted in using water irrigation.

Abstract Wheat is a plastic crop and therefore occupies a huge area, spreading in the north to the cold pole (Verkhoyansk), and in the south to the border of cultivation of cultivated plants. In some regions of Azerbaijan, it is sown in fields below sea level, and in Peru, it rises in the mountains up to 4000 m. Cultivation of wheat on a huge territory is possible due to the high adaptive properties of the culture, its resistance to frost and drought. Almost half of the bread composition is represented by carbohydrates, in which starch takes the main place (up to 80%). Under the influence of enzymes, it is broken down to simple sugars that the body needs. The total digestibility of bread carbohydrates reaches 90-92%. The protein substances of bread are of the utmost importance, thanks to which a third of a person’s daily needs are often covered in our diet. Bread is the main source of supply for the body with vitamins B1, B2, PP. It is rich in phosphorus, potassium, magnesium, sulfur.

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.

The effect of F. culmorum inoculation on the yield and quality of grain of AF Cesar and AF Lucius barley varieties was monitored. Field experiments were conducted between 2015-2017 at two locations. In grain harvested from plots grown under natural infection conditions, the deoxynivalenol content was very low. Inoculation caused a decline in germination, a certain reduction in yield and a change in some qualitative parameters (reduction in protein and fiber content, increase in starch content), but the effect of inoculation was weak and significantly influenced by the environment and the variety. The β-glucan content was not affected by inoculation. The varieties differed significantly from each other in β-glucan content (AF Cesar > AF Lucius). The deoxynivalenol content of both varieties was comparable after the inoculation while it differed under conditions of the natural infection (AF Cesar < AF Lucius).
