“…In earlier growth stages, full irrigation can supply enough water to plants and thus maintain adequate turgor, which improves the development and growth of plant stem and branches (Shiri-e-Janagard et al 2009). Full irrigation permitted optimum transpiration and faster growth of the aerial parts (Quezada et al 2011;Khakbazan et al 2011). Application of HA further improved vegetative growth traits compared with the control plants (Table 1).…”

This study assessed effects of irrigation water regimes and humic acid (HA) application on vegetative growth, yield, tuber quality and water use efficiency (WUE) of potato. Five irrigation treatments were applied at three developmental stages; (WR1) control (100 % crop evapotranspiration, 100 % ETc) at all plant growth, (WR2) 75 % ETc at all stages, (WR3) 75 % ETc at stage S1 (vegetative growth), (WR4) 75 % ETc at stage S2 (tuber initiation), and (WR5) 75 % ETc at stage S3 (tuber bulking). HA was applied at a rate of 1.5 g L −1 30 day after seed pieces planting. Plants experiencing water stress at S1 were shorter with fewer branches and lower fresh and dry vine weights. Water stress imposed at S2 significantly reduced tuber number, size, and yield. HA application increased vegetative growth, tuber weight, yield, WUE, and tuber quality (specific gravity and starch content). Thus, applying 1.5 g L −1 HA during vegetative growth and a 75 % ET water regime at S3 can increase potato production and tuber quality while reducing water use.Resumen En este estudio se evaluaron los efectos de los regímenes de agua de riego y la aplicación del ácido húmico (HA) en el crecimiento de la planta, rendimiento, calidad de tubérculo y la eficiencia del uso del agua (WUE) de la papa. Se aplicaron cinco tratamientos de riego en tres estados de desarrollo; (WR1) testigo (100 % evapotranspiración del cultivo, 100 % ETc) a todo el crecimiento vegetativo, (WR2) 75 % ETc en todas las etapas, (WR3) 75 % ETc en la etapa S1 (crecimiento vegetativo), (WR4) 75 % ETc en la etapa S2 (iniciación de tubérculo), y (WR5) 75 % ETc en la etapa S3 (llenado de tubérculo). Se aplicó HA a un nivel de 1.5 g*L-1 30 días después de la siembra de las unidades de semilla. Las plantas que experimentaron agobio hídrico en S1 fueron más cortas con menos ramas y pesos más bajos fresco y seco del follaje. El agobio hídrico impuesto en S2 redujo significativamente el número de tubérculos, el tamaño y el rendimiento. La aplicación de HA aumentó el crecimiento vegetativo, el peso de tubérculo, el rendimiento, WUE, y la calidad del tubérculo (gravedad específica y contenido de almidón). De aquí que la aplicación de 1.5 g*L-1 de HA durante el crecimiento vegetativo y un régimen de agua de 75 % de ET en S3 puede aumentar la producción de papa y la calidad del tubérculo mientras se reduce el uso del agua.

“…Water use efficiency and water expanse efficiency was recorded the highest with irrigation by drip irrigation method (M 2 ) at 0.4 IW/CPE ratio followed by micro sprinkler method (M 1 ) at 0.4 IW/CPE ratio and the lowest Water expense efficiency and water use efficiency were recorded under surface irrigation method (M 3 ) and 1.0 IW/CPE ratios (Table 5). Quezada et al (2011) reported that, the lower water use efficiency at 1.2 IW/CPE and 100 per cent CPE might be due to a greater expense of water use and comparatively lower yield in carrot. This might be on account of ease with which moisture was available for crop growth due to more number of irrigations resulted in application of more quantity of water which enhanced the CU of water by luxuriant growing plant body which in turn increased the evapotranspiration losses.…”

The current study was carried out to investigate the effect of different irrigation methods with water level based on IW/CPE ratio on growth and seed yield of fenugreek during the rabi season of 2 consecutive years (2016-17) at ICAR-National Research Centre on Seed Spices (NRCSS), Tabiji, Ajmer, Rajasthan. This investigation consisted of four irrigation regimes (IW/CPE ratio viz 0.4, 0.6, 0.8 and 1.0) and three irrigation methods ie. (Micro sprinkler, Drip irrigation and Surface irrigation). The experiment was laid out in factorial randomized block design with four replications. Among the irrigation methods tested, drip and micro sprinkler system gave maximum irrigation efficiency and minimum yield loss than surface irrigation. Results showed that irrigation regimes 0.6 IW/CPE ratio with drip irrigation gave superior seed yields (2049.80 kg ha-1) of fenugreek compared to other treatments. Total water applied was 321.96 mm by different irrigation methods. Water productivity and water use efficiency was found highest in 0.4 IW/CPE ratio followed by 0.6 IW/CPE ratio from the finding of the investigation. It was inferred that farmers were over irrigating their farms without equivalent returns. The water saved through use of optimized irrigation method and level can be used more profitably to irrigate supplemental lands, thus achieving a more efficient and rational use of land and water resources.

“…Soil moisture, fertilizer and temperature are important factors affecting plant growth and agricultural production (Quezada et al 2011;Hattori et al 2013). Soil moisture can play a vital role in the mineralization process of fertilizers and organic amendments, which release nutrients in soil for use by plants.…”

Potassium utilization efficiency (KUE) for plants is related to genotype difference, soil characteristics, application of fertilizer and irrigation. Up to now, the KUE of different genotypes worldwide has been extensively studied, but the influence of environment stress on KUE of cotton is infrequently reported. Thus, we selected a high K utilization efficiency cotton genotype (HEG) and a low K utilization efficiency cotton genotype (LEG) as indicator plants. The results showed that both soil water stress and K stress limited the growth of cotton genotypes. The change of soil water levels had significant influence on yield, KUE, rates of fallen leaves and bolls (RF), biomass and potassium accumulation in cotton. Deficient of soil water restricted the uptake and translocation of K. The absence of soil K greatly increased the proportion of biomass of reproductive organs and K distribution to reproductive organs in this experiment. The HEG exhibited higher physiological compared with LEG under the stress conditions, especially under low K treatment.
