Effect of irrigation interval on water consumption, water use efficiency, growth and yield of rice in two area of Sulaymani governorate

The different of locations (which has different in soil and water quality) and irrigation interval has an important influence on water use efficiency and rice crop yield to determine the effects of different irrigation water management on yield and water use efficiency of rice (Oryza sativa L.) in two different locations soils and water quality, the two-field experiments were conducted on silty clay loam and silty clay soil, in earthen and western Suleimani province of Kurdistan-Iraq The experiment was a complete randomized design with a factorial arrangement of treatments with three replications. The main treatment was Irrigation interval (full irrigation (D1), one day (D2), two days (D3), and three-day irrigation (D4)) The depth irrigation were 939, 811, 726 and 681 mm, respectively for qaragol, while for chalax the depth irrigation were 980, 821, 749 and 722 mm respectively. The sub- treatment was, Qaragol (L1) and chalax (L2) locations respectively, the results showed that the effects of irrigation interval and locations and their interaction on rice grain yield and water use efficiency were significant at 5%. The highest grain yield (6263 Kg ha-1) belonged to the (L2) location and the lowest grain yield (5823.3 Kg ha-1) belonged to (L1) in Qaragol location. And the highest water use efficiency 8.547 in Qaragol location belongs to the (D4) and the lowest water use efficiency 6.387 increasing of water use efficiency (D1 vs. D4) caused a 29.5% improvement in water use efficiency. The irrigation schedule can be planned to save water without considerable reduction of crop yield

Hidrogel za poboljšanje biljne biomase i relativnog sadržaja vode u listovima kod mirođije i piskavice

Drought is the most important abiotic stress in arid and semi-arid regions of the world and causes a decrease in the yield of agricultural plants. One of the ways to deal with drought is the use of hydrogels. Two pot experiments were conducted to study the effect of hydrogel polymer on the growth and the physiological traits of fenugreek and dill plants. The study was carried out as a factorial experiment in a completely randomized design. The experiment included two factors: hydrogel polymer rates (0, 0.02, 0.04, and 0.08 grams per kilogram of soil) and irrigation intervals (irrigation intervals of 3 and 6 days). Results showed that leaf, stem and seedling fresh and dry weight were increased by hydrogel polymer application in both plant species. Hydrogel polymer increased leaf relative water content but decreased chlorophyll content. Plants treated with the polymer applied at 0.08 g kg-1 produced the highest dry matter. The improvement was probably due to the increased leaf relative water content. The highest dry weight of the seedling was measured in plants treated with the polymer applied at 0.08 g kg-1 , whereas the lowest seedling dry weight was found in plants that were not treated with the polymer. The effect of irrigation interval on growth characteristics of both plant species was not significant. Overall, the use of hydrogel improves plant biomass in dill and fenugreek. Application of amounts higher than 0.08 g/kg of hydrogel on dill and fenugreek is recommended for further research.

Effects of Irrigation Interval and Planting Spacing on the Establishment and Growth of Faidherbia albida (Del.) A. Chev. Transplants in Arid Land Soils

The study aimed to assess the establishment of Faidherbiaalbida transplants under the effect of irrigation intervals and plantingspacing in the field conditions. It consisted of three irrigation intervals of5, 10 and 15 days and three planting spacings of 1x1 m, 1x2 m, and 2x3m; and it was conducted in the premises of the Forest Research Center,Khartoum, during May 2008 to June 2009. The results showed that thetemporal growth rate of F. albida shoot heights was greater in winter(November-February), but it was seriously slowed during the summerperiod (March-June). The shoot height, diameter and biomass growth ofF. albida increased with decreasing irrigation intervals; the growth ofthese parameters was highest in 5 days interval and lowest in 15 daysinterval. Planting spacings had no direct definite effect on F. albidaseedlings’ growth parameters. Even though, in the longer irrigationintervals, transplants’ growth tented to be greater in the wider spacing.Root biomass development seemed to be higher in the longer irrigationinterval regimes. There were no significant differences in the foliarnutrient content of the transplants between the different irrigationintervals. The values of mineral elements measured in this study areindicative of moderate nutrient supply for the F. albida transplants

Effect of Irrigation Interval and Nitrogen and Phosphorus Fertilizers on Forage Yield and Water Productivity of Fodder Barley (Hordium vulgare L.) in Gezira

An experiment was conducted during three consecutiveseasons viz 2003/04, 2004/05 and 2005/06, at Gezira Research StationFarm (latitude 14°24'N, longitude 33°31'E, and altitude 405 m asl) todetermine the optimum irrigation interval and nitrogen and phosphorusfertilization of barley (Hordium vulgare L.) for forage. Experimentaldesign was split-split plot design with three replications. Three irrigationintervals, viz every 10 days (W1), 15 days (W2) and 20 days (W3) wereassigned to the main plots, two phosphorus levels, (0P) and 96 kg P 2 O5 /ha (1P) were assigned to the subplots and three nitrogen levels (0N), 96(1N) and 192 kg urea/ ha (2N) were assigned to the sub subplots. Theexperiment was run during the 3 rd week of November, with a local varietyof barley (Baladi). Quantity of the applied water, dry matter yield at milkstage and of dry forage water productivity (kg dry matter / m 3 of appliedwater) were determined. The three years mean quantity of water appliedto the treatments W1, W2 and W3 were 4525, 4320 and 4290 m 3 / ha,respectively. The dry matter yields of barley in the three seasonsdecreased with increase of the irrigation interval. The comparativelyhigher dry matter yield in 2004/05 was attributed to lower day/ nighttemperatures during tillering - milk stage (30 - 75 days after sowing). Thethree years dry forage water productivities were 1.07 kg/m 3 (W1), 0.82kg/m 3 (W2) and 0.71 kg/m 3 (W3). The forage yield increased withincrease in level of N fertilization. The effect of P fertilization on drymatter yield was not significant. The highest dry matter yield wasassociated with the combination of irrigation every 10 days and 192 kgurea /ha.Key words: Barley; forage production; irrigation intervals, N and Pfertilization

Performance of Lucerne (Medicago sativa L.) Under semi-arid Environment. I: Effects of irrigation regime and irrigation system on fodder yield of Lucerne

A field experiment was conducted during January to August2007, 2008 and 2009 in the Demonstration Farm of the Faculty ofAgriculture, University of Khartoum lat. 15°40 ́N. Long. 32° 32- and 380m asl. The objectives of the experiment were to study the effect ofirrigation intervals of 8 (W 1 ) and 12 (W 2 ) days both of which received 8mm/day and 96 mm/day respectively. In addition the efficiency ofsprinkler and drip irrigation in production of lucerne fodder under the twoirrigation intervals was evaluated. The stability or variability of fodderyield from monthly cuts with seasonal weather changes was also studied.The results of the experiment showed that the irrigation interval (W 1 )consistently produced higher yield/cut in the three years. Drip irrigationproduced higher fodder yield than the sprinkler during the experimentalperiod at both the irrigation intervals. The yield of fodder was higherduring the cool months of January and February and declined during thehot months of March, April and May. Further decline in fodder yieldresulted during the monsoon months of June, July and August.

Effects of irrigation intervals and foliar application of amino acids and humic acid on the physiological traits of strawberries under colored shading nets

BACKGROUND: The strawberry is an important commercial crop, the improvement of its yield and quality is an imperative task. OBJECTIVE: The present research aimed to study the effect of colored netting and foliar application of amino acids on the physiological characteristics of strawberries subjected to different irrigation intervals. METHODS: The study was carried out as a factorial experiment based on a randomized complete block design with three factors including colored net at 4 levels (no netting, green, red, and yellow netting), organic acids at 4 levels (control, humic acid, glutamine, and arginine), and three levels of irrigation intervals (2, 4, and 6 days) in the greenhouse of Lahijan Agricultural Research Station, Iran. RESULTS: The results showed that the highest leaf number, shoot weight, chlorophyll and carotenoid content were related to yellow netting. The highest fruit yield, anthocyanins, and flavonoids were observed in the treatments of no-netting, green netting, and red netting, respectively. Data for the effect of organic acids showed that the glutamine-treated plants exhibited the highest yield, the humic acid-treated plants displayed the highest anthocyanin and carotenoid content, and the arginine-treated plants demonstrated the highest vitamin C content. The irrigation interval of 6 days caused to the lowest leaf number, flower and fruit number, shoot weight, fruit yield, and carotenoid content. Data for the trilateral effect of ‘netting×organic acid×irrigation’ showed that the highest flower number and fruit yield were obtained from ‘green netting×glutamine×4 days’, the highest anthocyanin content was obtained from ‘green netting×humic acid×2 days’, and the highest chlorophyll content was obtained from ‘green netting×control×6 days’. The treatment of ‘yellow netting×control×2 days’ was related to the highest flavonoid content. CONCLUSIONS: The application of colored nets provides the strawberry with more optimal vegetative and reproductive growth.

Effect of Irrigation Intervals and Manure Rates on Agronomic Parameters of Dill at Different Agro-ecological Zones of Bhutan

The effect of different irrigation intervals and manure rates on agronomic parameters of dill were evaluated under three agro-ecological zones of Bhutan: ARDC-Bajo located at 1200 m asl, ARDC–Wengkhar at 1,700 m asl, and NCOA–Yusipang at 2700 m asl. The split-plot design arranged in randomized complete blocks with three replications was employed. The four levels of irrigation interval (control, every 3 days, every 7 days, and every 14 days) were allotted to main plots and four levels of manure (Control, 4 tons/acre, 8 tons/acre and 12 tons/acre) were allocated to subplots. The results showed that dill can be successfully grown in all agro-ecological zones under study. Fresh yield obtained at ARDC-Wengkhar (1.92 tons/acre) was significantly higher compared to that at NCOA-Yusipang (0.52 tons/acre) but not significant to that at ARDC-Bajo (1.41 tons/acre). Interaction of irrigation interval and manure rate significantly influenced plant height (P=0.02) and stem diameter (P=0.03) at NCOA–Yusipang, and stem per plant (P=0.02) at ARDC-Wengkhar. The irrigation interval of 3 days produced significantly better results except for the fresh to dry weight ratio at NCOA-Yusipang. Irrigation interval of 7 days yielded better results at ARDC-Bajo and ARDC-Wengkhar except for FDR at ARDC-Wengkhar. The increase in irrigation interval beyond 7 days resulted in 62% and 25% lower fresh yields at ARDC-Bajo and NCOA-Yusipang respectively. In contrast, irrigation at 3 days interval at ARDC–Wengkhar decreased the yield by 55% compared to 7 days interval. The manure treatments did not influence any of the parameters assessed at all sites. However, MR 8 tons/acre at NCOA–Yusipang, MR Control at ARDC-Wengkhar and MR 12 tons/acre at ARDC-Bajo yielded higher fresh yields compared to other manure treatments. We recommend the combined application of IR 7 days x MR 12 tons/acre, IR 7 days x MR 4 tons/acre, and IR 3 days x 8 tons/acre at ARDC–Bajo, ARDC-Wengkhar and NCOA–Yusipang respectively. Further, this research provides a reference guide for agricultural extensionists during promotional, advocacy and capacity development programs.

Review on the Effect of Irrigation Interval on Different Crop Production

In these review I have been review the effect of irrigation intervals on growth and yield of onion, effect of irrigation intervals to optimize maize yield, effect of irrigation interval on growth characteristics for Chile pepper, effect of irrigation interval on vegetative growth and yield, effects of irrigation interval on growth analysis of soybean, effect of irrigation intervals on forage production, effect of irrigation interval on growth and development of tomato, effect of irrigation level and irrigation frequency on the growth of mini Chinese cabbage and Influence of irrigation interval, nitrogen level and crop geometry on production lettuce. The best performance irrigation interval for maize, pepper, okra, soybean, forage, tomato, cabbage and lettuce are 5, 6, 1, 12, 8, 20, 1, 4 and 2 day respectively. Crop type, crop growth stage soil type, climate condition (temperature, rainfall, humidity, sunshine hour and wend speed) duration of the environment should be properly addressed and potential evapotranspiration and reference evapotranspiration should be estimated for determine of irrigating interval. In in these case some of the studies are properly addressed these important parameters but some of the study not indicates. On the other hand chemical composition of water and soil, fertilizer application, method of research design and plant geometry are should be identify to eradicate the misjudgment of your best productivity of irrigation interval.
