An experiment was conducted to study the effect of crop geometry and irrigation levels on sugarcane under drip irrigation at Main Sugarcane Research Station, Junagadh Agricultural University, Kodinar during 2011-14. The treatment consisted of three crop geometry (90 cm normal planting, paired row planting (60: 90 cm) and paired row planting (60: 120 cm) and three drip irrigation levels (0.5 PEF, 0.7 PEF and 0.9 PEF) and with an extra treatment (control) having surface irrigation (90 cm) at 1.0 IW/CPE ratio. Experimental results indicated that paired row (60: 90 cm) planting gave significantly higher cane yield (101.04 t/ha) over 60: 120 cm paired row planting (88.82 t/ha) and remained at par with 90 cm row spacing (97.34 t/ha). Drip irrigation level of 0.9 PEF gave significantly higher cane yield (108.63 t/ha) over 0.7 PEF (96.01 t/ha) and 0.5 PEF (82.56 t/ha). Juice quality parameters like brix, sucrose, purity and sugar recovery percent were not affected significantly due to either crop geometry or different drip irrigation levels. Significantly higher cane yield was recorded under drip irrigation (95.74 t/ha) compared to surface irrigation (76.86 t/ha). The total water use was not affected due to different crop geometries. Water use decreased constantly in 0.7 and 0.5 PEF compared to 0.9 PEF and accordingly WUE increased.

The effect of irrigation and bio-stimulant (ComCat) applications on fruit quality parameters at the ‘Rubygem’ strawberry variety was investigated. The amounts of irrigation water applied were 0.50, 0.75, 1.00 and 1.25 times of water surface evaporation measured Class A pan placed over the crop canopy and the corresponding regimes were denoted as IR50, IR75, IR100 and IR125. Furthermore, bio-stimulant is applied four times with three weeks interval, approximately two months after planting. Applications of bio-stimulant were not efficient on examined parameters. Decreasing of the irrigation levels were significantly increased TSS and sugar/acid ratio which affects the fruit taste. The highest TSS and sugar/acid ratio was determined at IR50 plot with 9.42% and 21.7 values, respectively. However, fruit weight was significantly decreased except of IR100 plot. Moreover, deficient irrigation (IR50 and IR75) may cause a decrease at fruit weight. Recently, it could be crucial strategy to improve sugar and sugar/acid ratio which were prominent for consumers on the eating quality. Also, improving fruit taste with bio-stimulant application at optimum irrigation level (IR100) without any decreasing of fruit weight was determined.

Although water-saving measures are increasingly being adopted in orchards, little is known about how different irrigation methods enhance water use efficiency at the root system level. To study the allocation of water sources of water absorption by cherry roots under two irrigation methods, surface irrigation and drip irrigation, oxygen isotope tracing and root excavation were used in this study. We found that different irrigation methods have different effects on the average δ18O content of soil water in the soil profile. The IsoSource model was applied to calculate the contribution rate of water absorption by cherry roots under these irrigation methods. During the drought period in spring (also a key period of water consumption for cherry trees), irrigation water was the main source of water absorbed by cherry roots. In summer, cherry roots exhibited a wide range of water absorption sources. In this case, relative to the surface irrigation mode, the drip irrigation mode demonstrated higher irrigation water use efficiency. After two years of the above experiment, root excavation was used to analyze the effects of these irrigation methods on the distribution pattern of roots. We found that root distribution is mainly affected by soil depth. The root system indexes in 10–30 cm soil layer differ significantly from those in other soil layers. Drip irrigation increased the root length density (RLD) and root surface area (RSA) in the shallow soil. There was no significant difference in root biomass density (RBD) and root volume ratio (RVR) between the two irrigation treatments. The effects of these irrigation methods on the 2D distribution of cherry RBD, RLD, RSA and RVR, which indicated that the cherry roots were mainly concentrated in the horizontal depths of 20 to 100 cm, which was related to the irrigation wet zone. In the current experiment, more than 85% of cherry roots were distributed in the space with horizontal radius of 0 to 100 cm and vertical depth of 0 to 80 cm; above 95% of cherry roots were distributed in the space with the horizontal radius of 0 to 150 cm and the vertical depth of 0 to 80 cm. Compared with surface irrigation, drip irrigation makes RLD and RSA more concentrated in the horizontal range of 30–100 cm and vertical range of 0–70 cm.

The foliar application of nutrients help the plant leaves to readily absorb the applied nutrients through the nutrient solution and increases the nutrient use efficiency and thus improves the crop yield. The field experiment was conducted for two consecutive years to find out the affect of foliar spray of NPK and micronutrient on cane yield, yield parameters and juice quality of sugarcane during 2019-20 and 2020-21.The present study was carried out on clay loam soils of Research farm of Regional Research Station, CCS Haryana Agricultural University, Karnal, Haryana. The research revealed that cane yield and yield parameters i.e., cane length, and cane weight was significantly affected with the foliar spray of NPK and micronutrient but non-significant effect was observed for cane girth and number of internodes. With respect to juice quality parameters viz., commercial cane sugar (CCS) %, pol % and sugar yield, significantly affected with foliar spray of NPK and micronutrient. The highest cane yield, cane weight and cane length was recorded with the foliar application of 2% NPK (19:19:19) + 0.5% ZnSO4 +1% FeSO4 (78.16 t/ha, 1.21 kg and 207.3 cm) followed by foliar spray of 0.5% ZnSO4 + 1% FeSO4+ 2.5% urea recorded 76.75 t/ha, 1.20 kg and 207.1 cm, respectively. The lowest cane yield (70.68 t/ha) was recorded with the application of recommended dose of fertilizer (RDF) alone. The highest CCS % (12.16), pol % (17.36) and sugar yield (9.51 t/ha) was observed in the treatment 2% NPK + 0.5% ZnSO4 +1% FeSO4. Thus, foliar application with NPK and micronutrient could significantly improve the cane yield, yield parameters and juice quality of sugarcane crop.

Abstract Production of quality greenhouse and nursery crops is dependent on high quality and quantities of water. At present, in some regions, insufficient water supply is a growing concern. This study was conducted to evaluate growth of New Guinea impatiens (Impatiens hawkerii 'Celebrate Salmon'), when watered with a polyoxyethylenesorbitan monolaurate (C58H114O26) solution commercially known as Tween 20, at differing irrigation levels compared with a conventional water regimen without the surfactant, and also to determine how Tween 20 would affect photosynthesis and transpiration. The treatment design was a 3 by 6 complete factorial design plus a control. The two factors were irrigation and Tween 20. Irrigation levels of 20%, 40%, or 60% of the full crop evapotranspiration (ET) requirements were used in combination with Tween 20 concentrations of either 0, 25, 50, 75, 100, or 125 mg·L−1 (0, 0.003338, 0.00668, 0.0100145, 0.01335, or 0.01669 oz per gallon). The control group was watered with tap water to container capacity with about 30% leachate. Evapotranspiration was determined as the difference of the applied water amount minus the leachate of the control. Plants irrigated with Tween 20 from 25 to 125 mg·L−1 (0.003338 to 0.01669 oz per gallon) at the 40% or 60% irrigation level had the same height and growth index as plants in the control after three months of growth. Plant fresh and dry weights were not different between the control and the treatments of Tween 20 from 50 to 125 mg·L−1 (0.00668 to 0.01669 oz per gallon) at the 60% irrigation level or the treatment of Tween 20 at 100 mg·L−1 (0.01335 oz per gallon) at the 40% irrigation level. Tween 20 had no effect on net photosynthetic rate. Tween 20 decreased the amount of transpired water of New Guinea impatiens 'Celebrate Salmon'. When the Tween 20 concentration increased from 0 to 100 mg·L−1 (0 to 0.01335 oz per gallon) at the 60% irrigation level, the transpiration rate and stomatal conductance decreased markedly by 43% and 47%, respectively, and water use efficiency was increased by 47%. Results from this study suggest that Tween 20 is able to increase plant water use efficiency through regulation of stomatal conductance or transpiration under deficit irrigation.

The field experiment was conducted to study the effect on yield, water use, economics and storability of onion during rabi season of 2014-17 at Interfaculty Department of Irrigation Water Management, MPKV Rahuri. The experiment comprised of 100, 80 and 60 per cent recommended dose of fertilizer through fertigation, irrigation N and K through drip and P application in soil, drip with conventional fertilizers application in soil, surface irrigation with conventional fertilizers as control and micro-sprinkler irrigation with 100 % RDF through fertigation. The drip irrigation was beneficial than surface irrigation in increasing the yield (78.8 %) and saving the fertilizer. The total seasonal water requirement in drip irrigation was 480.3 mm compared to 807.2 mm in surface irrigation. The drip irrigation with 100 % RDF though fertigation was profitable higher net seasonal income of Rs. 2,74,445 per ha, compared to control (Rs.1,41,955 per ha) with B:C of 4.62 and water productivity of Rs. 566 per mm of water used. The micro-sprinkler irrigation with 100 % RDF through fertigation had significantly maximum total storage losses of 21.10 per cent followed by surface irrigation with 100 % RD of conventional fertilizer (19.86 %) and drip irrigation with 100 % RDF through fertigation. The results revealed that drip fertigation with 100 % RDF through fertigation in 13 weekly splits as per schedule is the best treatment to improve the yield, economical returns and storability of onion (var. N-2-4-1) cultivated in silty clay loam soils of Western Maharashtra.

Irrigation Levels

With water resources constantly becoming scarcer, and 70% of freshwater used for the agriculture sector, there is a growing need for innovative methods to increase water use efficiency (WUE) of food production systems and provide nutrient-dense food to an increasing population. Sensor technology has recently been introduced to the horticulture industry to increase resource use efficiency and minimize the environmental impacts of excessive water use. Identifying the effects of irrigation levels on crop performance is crucial for the success of sensor-based water management. This research aimed to optimize WUE in a soilless microgreen production system through identification of an optimal irrigation level using a sensor that could facilitate the development of a more efficient, low-cost automated irrigation system. A dielectric moisture sensor was implemented to monitor water levels at five irrigation setpoints: 7.5, 17.5, 25, 30, and 35 percent of the effective volume of the container (EVC) during a 14-day growth cycle. To validate the sensor performance, the same irrigation levels were applied to a parallel trial, without sensor, and water levels were monitored gravimetrically. Plant water status and stress reaction were evaluated using infrared thermal imaging, and the accumulation of osmolytes (proline) was determined. Results showed that, proline concentration, canopy temperature (Tc), canopy temperature depression (CTD), and crop water stress index (CWSI) increased at 7.5% EVC in both sensor-based and gravimetric treatments, and infrared index (Ig) and fresh yield decreased. The dielectric moisture sensor was effective in increasing WUE. The irrigation level of 17.5% EVC was found to be optimal. It resulted in a WUE of 88 g/L, an improvement of 30% over the gravimetric method at the same irrigation level. Furthermore, fresh yield increased by 11.5%. The outcome of this study could contribute to the automation of precision irrigation in hydroponically grown microgreens.

ABSTRACT The use of shading screen in vegetable crops sensitive to the radiation excess, associated with the effective water use via irrigation, allows for yield gains. This study aimed to evaluate the yield characteristics of cherry tomato cultivated with and without shading screen and different irrigation levels. A randomized block design was used, in a 4 x 2 factorial arrangement, with four irrigation levels (140 %, 160 %, 180 % and 200 % of the reference evapotranspiration - ETo) and two cherry tomato hybrids (Wanda and Dolcetto). The irrigation level corresponding to 200 % of the ETo provided the highest values for number of flowers and clusters formed, number of fruits per plant and fruit diameter. The Wanda hybrid was more fruitful, with a higher emission of clusters, while Dolcetto was more floriferous. The use of shade screen for cultivating cherry tomato provides an increase in the yield characteristics, if compared to the cultivation in open areas.

Abstract. Irrigation amount is one of the most important factors that need to be considered in the management of center-pivot irrigation systems for alfalfa producers. In 2014 and 2015, a field study was conducted at Saiwusu, Inner Mongolia, China. Three irrigation levels (100%, 80%, 60% ET) were used to evaluate the effects of irrigation amount on alfalfa yield and quality. For assessing the effects of water distribution variation of center-pivot systems on alfalfa yield and quality, the water application depth, alfalfa yield, and quality between the first span, second span, overhang, and end gun were also compared. The results showed no significant difference in annual yield between the 100% and 80% ET irrigation levels. Compared to irrigation at 100% and 80% ET, irrigation at 60% ET caused significant reductions in yield of 10% and 11%, respectively. As the irrigation amount decreased, total crop water use significantly declined from 617 to 405 mm, and water use efficiency (WUE) increased from 21.8 to 29.8 kg ha-1 mm-1. The water production functions of alfalfa were parabolic for each harvest. The proportions of seasonal actual water applied to each cutting were approximately 25%, 32%, and 43%, with contributions to annual yield accounting for 54%, 30%, and 16%, respectively, indicating that the third harvest of alfalfa had great potential for improving WUE and saving water. Irrigation level had a noticeable effect on the relative feed value (RFV) but no effect on crude protein (CP) concentration. The 60% ET irrigation level was conductive to increased CP concentration and RFV of alfalfa but was of no help to improve alfalfa quality grade. The spatial distributions of annual yield and quality were highly related to the spatial distribution of water for the center-pivot system. The coefficients of variation (CVs) for annual yield, RFV, and CP of the whole system were 5% to 12%, 2% to 8%, and 1% to 8%, respectively, while the CVs for actual irrigation amount ranged from 11% to 13%. Over-irrigation caused by the end gun slightly increased alfalfa annual yield, but it reduced the quality and WUE. Therefore, the end gun in a center-pivot irrigation system should be carefully selected for improving the uniformity of water application. The 80% ET irrigation level in the first and second cuttings and the 60% ET irrigation level in the third cutting are recommended for alfalfa production in semi-arid regions, such as western Inner Mongolia in China. Keywords: Alfalfa, Center-pivot irrigation, Quality, Water management, Yield.

Agriculture uses more than 80% of water resources in Morocco. The sector isinefficient in terms of water use due to the dominance of surface irrigation. Toaddress this issue, there have been efforts in Moroccan strategies to convert surfaceirrigation to localized one. This paper analyses the dynamics of conversion fromsurface irrigation to drip irrigation in Fez-Meknes region (north-eastern Morocco)through the lens of the Multi-Level Perspective (MLP) on socio-technicaltransitions. MLP framework suggests that transitions are the results of dialecticinteractions among a niche (cf. novelty of drip irrigation), a regime (cf. traditionalsystem of surface irrigation) and the socio-technical landscape (e.g. policies). MLPwas complemented with a multi-capital approach to better assess transitionimpacts. Results show that the area equipped with drip irrigation in Fez-Meknesregion increased from 2174 ha in 2008 to 39290 ha in 2016. Different programshave been implemented in the framework of the Green Morocco Plan to fosterirrigation transition e.g. the National Irrigation Water Saving Program (PNEEI),launched in 2007, aims to convert 550,000 ha to localized irrigation (e.g. dripirrigation) in 15 years. Thanks to these programs, financial and technical supporthas been provided to farmers to promote the adoption of water-saving irrigationtechniques and practices. Farm-level results show that transition to localizedirrigation decreases irrigation water use, increases yields and profitability (cf. grossmargin per ha), and improves water productivity. Despite an enabling policylandscape and positive transition impacts, surface irrigation is still maintained inthe region and farmers are reluctant to change for many reasons (e.g. age andeducation level, unclear land tenure, financial and administrative difficulties).Efforts are still needed to train farmers on irrigation scheduling and on the use ofsmart irrigation techniques to save water. Further research is required to betterunderstand current bottlenecks in the irrigation transition process and designappropriate and context-specific transition governance strategies.
