“…However, potato tuber yield also decreased as irrigation water applied resulted in excessive irrigation (U23, U13 and U3) creating more wetting stress on plant roots, causing more vegetative growth, and potential leaching of nutrients from the root zone. Similar results were obtained by [10], and [9] working on potato [25] working on pepper, [26] working on cucumber, [4] working on squash and [27] working on pumpkin, all of them observed yield was negatively affected by either deficit or excessive irrigation conditions. For a given 33 rd in fall growing season under TF, PF, TP and TL methods, respectively.…”

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.

“…Water stress also decreased the accumulation of water in the fruit, fruit weight, and yield. Yavuz et al (2015) and Kuscu et al (2014) reported that crop yield increased with the amount of irrigation water, but the highest yield in our study was in I2 rather than at the highest level of irrigation. The optimum application of N amplified the effect of irrigation.…”

The objective of this study was to investigate the effects of applying different amounts of water and nitrogen on yield, fruit quality, water use efficiency (WUE), irrigation water use efficiency (IWUE) and nitrogen use efficiency (NUE) of drip-irrigated greenhouse tomatoes in northwestern China. The plants were irrigated every seven days at various proportions of 20-cm pan evaporation (E p). The experiment consisted of three irrigation levels (I1, 0.5 E p ; I2, 0.75 E p ; and I3, 1.0 E p) and three N application levels (N1, 150 kg N ha-1 ; N2, 250 kg N ha-1 ; and N3, 350 kg N ha-1). Tomato yield increased with the amount of applied irrigation water in I2 and then decreased in I3. WUE and IWUE were highest in I1. WUE was 16.5% lower in I2 than I1, but yield was 26.6% higher in I2 than I1. Tomato yield, WUE, and IWUE were significantly higher in N2 than N1 and N3. NUE decreased with increasing N levels but NUE increased with increase the amount of water applied. Increasing both water and N levels increased the foliar net photosynthetic rate. I1 and I2 treatments significantly increased the contents of total soluble solids (TSS), vitamin C (VC), lycopene, soluble sugars (SS), and organic acids (OA) and the sugar:acid ratio in the fruit and decreased the nitrate content. TSS, VC, lycopene, and SS contents were highest in N2. The harvest index was highest in I2N2. I2N2 provided the optimal combination of tomato yield, fruit quality, and WUE. The irrigation and fertilisation regime of 0.75 E p and 250 kg N ha-1 was the best strategy of water and N management for the production of drip-irrigated greenhouse tomato.

“…Every plant has specific water supply needs different amount in different time and in different soil depth (O`Shaughnessy, et al, 2012), (Yavuz, et al, 2015). Next variable in the decision process is soil -there is a need to consider all soil characteristics (Romero, et al, 2012) because of different water leakage and evaporation levels.…”

V souvislosti se změnami klimatu se setkáváme s prognózami o nedostatku srážek a vody k uspokojení potřeb obyvatel a zemědělců. O udržitelnosti těchto zdrojů rozhoduje hospodárnost při zemědělských a zahradních činnostech. Mezi tyto činnosti patří zavlažování a zalévání. Zde je prostor pro aplikaci inteligentních systémů pro udržitelné hospodaření s vodními zdroji.
