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.

A B S T R A C TThe therapeutic efficacy of herbal medicines and pesticides has increased the need to define cultivation parameters for medicinal plants. The objective of this study was to evaluate the production of essential oil and flavonoids of chamomile under irrigation levels and organic fertilizer doses. The experiment was conducted in the experimental area of the Campus II of the University of Western São Paulo, in the city of Presidente Prudente, SP, Brazil. The experimental design was a randomized block in triple factorial (6 x 2 x 3), corresponding to irrigation depths (150, 100, 75, 50, 25 and 0% of the reference evapotranspiration (ETo)), organic fertilizers (poultry manure and cattle manure) and the fertilizer doses (0, 3 and 5 kg m -2 ), with four replicates. The following variables were evaluated: capitulum dry matter, and content and yield of essential oil and flavonoids. For the tested conditions, it is recommended to use 5 kg m -2 poultry manure and water depth equivalent to 150% ETo for the production of essential oil and flavonoid.Irrigação e adubação orgânica na produção de óleo essencial e flavonoides em camomila R E S U M O A eficácia terapêutica de fitoterápicos e fitofármacos tem aumentado a necessidade de definir parâmetros de cultivo para plantas medicinais. O objetivo do presente trabalho foi avaliar a produção de óleo essencial e flavonoides da camomila quanto a lâminas de irrigação e doses de adubo orgânico. O experimento foi conduzido em área experimental do Campus II, da Universidade do Oeste Paulista, na cidade de Presidente Prudente, SP, Brasil. O delineamento experimental foi em blocos ao acaso em esquema fatorial triplo (6 x 2 x 3), sendo a lâmina de irrigação (150, 100, 75, 50, 25 e 0% da evapotranspiração de referência (ETo)), o adubo orgânico (esterco de aves e esterco bovino curtido) e a dose do adubo (0, 3 e 5 kg m -2 ) e quatro repetições. Foram avaliados a massa seca de capítulos florais, o teor e o rendimento de óleo essencial e o flavonoide; para as condições testadas recomenda-se utilizar 5 kg m -2 de esterco de ave e lâmina de irrigação equivalente a 150% ETo para a produção de óleo essencial e flavonoide. IntroductionChamomile is a medicinal and aromatic plant of great importance for the cosmetic and phytotherapeutic industry. It is the medicinal plant of greatest economic expression in the South region with cultivated area of 2,000 thousand ha in Paraná (Corrêa Júnior & Scheffer, 2014).Irrigation management consists in the rational use of water in order to meet the requirements of the plants, increasing production and water use efficiency (Shock & Wang, 2011;Pinto et al., 2014;Afshar et al., 2014). The water balance is one way of managing irrigation, considering the processes of absorption, conduction and loss of water. The difference between the water absorbed and lost by the plant is a relevant factor for the metabolic processes of adjustment of the plant (Bilibio et al., 2010).In situations of water deficit, medicinal plants can activate the secondary metaboli...

“…These results were in agreement with those reported by [12,13], however Mao et al [7] reported a polynomials relationship between ET and yield. In this study, treatment T 1 -100 had the highest yield and treatments T 3 , 4 , 5 , 6 -80 and T 12 -40 gave fairly good marketable yield with economically saving water, fertilizers and pesticide. The result also indicated that the water productivity (WP) increased with decrease the amount of applied water, the WP were 42.3 and 61.9 kgm -3 for T 1 -100 andT 12 -40, respectively.…”

“…Agele et al [5] concluded that seasonal crop ET values were greater during reproduction growth stage in the crop. Amer et al [6] concluded that the cucumber yield significantly decreased in linear relationship with increasing water deficit. However, no significant changed when water applied above 100%ETc.…”

Deficit irrigation can play an important role in increasing water use efficiency (WUE) and reduced amount of irrigation. Deficit irrigation generally refers to fully irrigated crops where water is reduced or withheld during certain growth stages. In this study, a series of greenhouse and open field experiments were conducted using a deficit irrigation program on cucumber crops under drip irrigation during 2007-2010 growing seasons. The layout of the experiment was a completely randomized design with four replicates. Irrigation treatments consisted of five levels of ETc (30, 40, 60, 80, and 100% of ETc) in addition to traditional practice by farmers. At 60 and 80% treatments, deficit irrigation tested at different growth stages (development, med, and late stages of the growth) for a total of 14 treatments at each experiment. The maximum amount of water applied to the crop was 332 mm for the 100%ETc treatment while the minimum water applied was 100 mm for 30%Etc treatment, and 600 mm for traditional practice by the farmers in the region. The calculated ETc ranged from between 95 and 316 mm for the different treatments. The objective of the study was to determine the crop water requirements in both the open field and greenhouse and calculate crop response factor (ky) and WUE of cucumber crop using a deficit irrigation program at different stages of growth. Results indicated that a cucumber could stand the shortage of water during the growth and crop response (Ky) values ranging between 0.7 and 0.98. However, the amount of water used was much lower than that of the traditional method used by farmers in the region. Water use efficiency (WUE) and water productivity (WP) values increased when water amounts decreased with the exception of the traditional irrigation; these values decreased to 45.6 and 24 kg/m 3 , respectively. The highest values at much stressed treatment 30% ETc.
