“…The authors stated a bigger average tuber weight in wetter than dry years and diversified response of varieties to moisture conditions concerning formation of the number of main stems but also the number of set tubers. Obtained results are compatible also with the reports of Badr et al (2012), who revealed that deficiency of water has a more unfavourable effect on average tuber weight than on the number of set tubers.…”

“…An average tuber weight is determined by many factors which directly or indirectly affect the value of this feature. Planting density, nitrogen fertilization, cultivar properties and moisture conditions have the greatest direct influence (Zebarth et al 2006, Lutra et al 2009, Badr et al 2012. The number of tubers per plant depends mainly on the number of main stems, which is a cultivar feature highly correlated with seed-potato size.…”

The effect of nitrogen fertilization and microbial preparations on yielding and development of potato tuber yield components were assessed in field experiments conducted under soil conditions of Luvic Chernozem. The factors of the experiment were nitrogen fertilization levels: 0, 60, 120 and 180 kg N/ha and the following preparations: BactoFil B10, effective microorganisms and UG max soil fertilizer. Nitrogen fertilization caused a significant increase in marketable yield of potato tubers. Yield increments on individual fertilizer treatments ranged from 66% to 140%. An evident effect of this factor was also visible regarding the yield components values. Increase in the number of main stems per 1 m 2 under the influence of growing nitrogen doses occurred from the fertilization level 120 kg N/ha, whereas the number of tubers per 1 stem increased only to the level of 60 kg N/ha. Each nitrogen dose applied within the range to 180 kg N/ha caused a marked increase in an average tuber weight. Conducted investigations demonstrated an unfavourable effect of microbial preparations on the marketable crop yield of tubers and formation of yield components. On the objects where microbial preparations were applied, the marketable yield was lower by 1.5 to 2.3 t/ha than in the control. Analysis of linear regression revealed occurrence of significant dependencies between the total tuber yield and the values of individual yield components. The relationships were the most visible for an average tuber weight formation as evidenced by the value of coefficient of determination (R 2 = 0.983).

“…They found that high frequency irrigation enhanced potato tuber growth and water use efficiency. Reducing irrigation frequency from once every day to once every 8 days resulted in significant yield reductions by 33.4% and 29.1% in 2001 and 2002, respectively. Potato is an important commercial crop that has gained popularity in the Mediterranean region [12]- [14]. Potato is normally grown in soil under conditions using trickle, sprinkler and furrow irrigation methods during spring and fall seasons in order to respond to the high demand of potato on both national and international markets.…”

Potato growth, yield, and quality under improved irrigation methods and non-uniformity of their irrigation applications are important to enhance water management in arid regions. A field experiment was conducted in 2014 spring and fall growing seasons using potato (Solanum tuberosum) grown in northern Egypt at Shibin El Kom, Menofia, Egypt to evaluate potato response to furrow or trickle irrigation. A Randomized Split-Plot Design with irrigation method randomly distributed and non-uniformity of irrigation applications evaluated along either irrigation furrow or trickle lateral as dependent variables measured at the 3 rd , 13 th , 23 rd , 33 rd , 43 rd and 53 rd m along the 55 m irrigation line. Traditional (TF) and partial (PF) furrows as well as trickle point (TP) and line (TL) sources were used as irrigation methods. Each treatment was repeated three times. For a 33 rd m treatment, seasonal optimum water use by potato was 328, 234, 269 and 292 mm over 118 days in spring and 200, 164, 178 and 186 mm over 122 days in fall under TF, PF, TP and TL irrigation methods, respectively. Potato tuber yield and quality were significantly affected by growing season (S), irrigation method (I) and non-uniformity of irrigation application (U). Tuber yield, total soluble solid (TSS) and leaf area index (LAI) were significantly affected by I and U, and their interaction I * U; harvest index (HI) was not affected by I but U. Except for TSS by S * I and HI by U * I and S * I, results showed no significant differences. Moreover, tuber weight, number and marketable yield were significantly affected by S, I, U and I * U interaction, except medium tuber size and culls by S. A given 33 rd treatment under partial furrow and trickle irrigation, relative to that of traditional furrow, enhanced tuber yield and improved quality in both growing seasons. In non-uniform irrigation application over two growing seasons, potato crop response was developed under varied irrigation methods. Tuber yields were significantly affected in a linear relationship (r 2 ≥ 0.75) by either water deficit or excessive water under irrigation methods.

“…On average, N removed per tonne of fruit was of similar magnitude to the values reported by Mullins et al (2007). However, these are very low values (∼10%) if compared to amounts of N usually removed by annual crops, such as maize and potato, which can amount to more than 200 kg N ha −1 (Kirda et al, 2005;Badr et al, 2012). The amounts of the other nutrients removed in grape were 3.2, 28.7, 8.2 and 2.5 kg ha −1 and 36.1 g ha −1 , respectively for P, K, Ca, Mg and B.…”

Guidelines for fertilizer use in vineyards based on nutrient content of grapevine parts

a b s t r a c tPlant analysis plays a major role in fertilizer recommendations for perennial tree crops and vines. Plant analysis, however, does not quantify the rate of nutrients to apply. The approach developed in this work takes into account the content of the nutrients in grapevine parts and their dynamic within the plant to assist in the estimation of the amount of fertilizer to apply. Groups of three vines were cut at ground level on four different dates from September 14th to November 28th. On the first sampling date the vines were separated into trunk, cordons, canes, leaves and clusters for determination of dry matter content and elemental composition. On the following dates the vines were separated into the plant parts that were still present, since the clusters were only present on the first sampling date and the leaves on the first two. To assess the mobility of nutrients within the plant, samples of phloem vessels and sawdust of the entire trunk were taken as well as samples of chlorotic and green leaves. Nitrogen (N), potassium (K), phosphorus (P) and boron (B) showed mobility within the plant whereas calcium (Ca) and magnesium (Mg) did not. The removal of nutrients in clusters is critical for estimating N and K fertilizer rates. Clusters removed 19.9 kg N ha −1 and 28.7 kg K ha −1 . In the case of N, it is also important to assess the system's ability to recycle the nutrient contained in the leaves and canes which amounted to 49.4 kg N ha −1 . Phosphorus, calcium and magnesium applications might not justify being taken into account in the annual fertilization plan. Thus, the establishment of the fertilization programme should be a nutrient-specific exercise which takes into account all sources of information, including target yield and nutrient content in clusters, the vineyard management strategies influencing nutrient use efficiency from fallen leaves and prunings and soil testing and plant analysis.
