the effect of irrigation intervals and consumption of super absorbent polymers on yield and yield components of the local mung beansinkhash region.  -  super absorbent material
Climate change and population growth are two important challenges facing agriculture in the world today.
Drought and the resulting pressure are the most common environmental pressures that limit agricultural products, so one of the most important limiting factors for agricultural products on semi-dry soil [11].
Every agricultural operation aimed at achieving high yield usually improves water consumption efficiency.
Water consumption efficiency of plants related to plant types, environmental conditions and weather conditions [12]
Mung bean has high production capacity under low moisture conditions [1].
Materials that can absorb at least 20 times their mass are named super absorbent materials.
The water absorption of these polymers depends on the amount of formula, water and salt, ranging from 20 to 2000 times the mass.
Green beans, yellow beans (L. )
Is the summer final of the short growing season planted by rain-fed method in Central and Southeast Asia [4].
The main key to saving more water and improving irrigation efficiency and maintaining sustainable irrigation agriculture is to determine the critical time of irrigation and the time of irrigation (
Water quantity and irrigation time)
Based on the real needs of the factory [8].
Ghasemi Golozary and others. (1997)
According to reports, the water stress of peas led to a decrease in green coverage and a decrease in unit yield per area.
Some researchers have reported an increase in grain protein under drought stress and believe that this will contribute to infiltration regulation and balance under water stress [2,3,5]. Shafiee [10]
In addition to better plant growth and reducing the negative effects of soil salt on plants, the use of super-absorbent polymers can save up to 50% of water consumption, he said.
Another advantage of super absorbent is to maintain moisture and nutrition for a long time, reduce the number of irrigation times, use water evenly for plants, grow faster and more ideal roots, reduce washing water and nutrition in soil, reduce irrigation costs, effective use of fertilizers, better soil ventilation, possibility of planting in desert and slope areas, increased activity and proliferation of fungi, and enhanced stability and stability of soil structures [9].
The materials and methods were tested in khash field (
Southeast Iran)
Determine the water spacing of local mung beans and the influence of the yield and yield components of super absorbent resin.
Kashgar city is located in the geographical location of 61 degrees 29 minutes east longitude, 31 degrees 13 minutes north latitude and 489 kilometers north latitude.
2 metres above sea level.
The soil texture of the experimental site is sand pile.
The chemical analysis results of the saturated fraction show that the conductivity (EC)of soil was 1. 34 dS/m.
The experiment was done in a split graph of 3 repeated completely random blocks.
The main plots are A1: 5 days irrigation, A2: 10 days irrigation and 3: 15 days irrigation at three levels of irrigation intervals.
The sub-graphs are S1: 0, S2: 15 kg/ha, S3: 30 kg/ha, S4: 45 kg/ha, and the super-absorbed polymer consumption at four levels.
In this experiment, superabsorbent polymers of dry particle type produced from deimgostaranatieh, Iran were used.
Results vs. discussion stem diameter: analysis of variance showed that stem diameter was not affected by irrigation intervals, but the application of super-absorbent polymers had a significant effect on stem diameter.
Biological yield: analysis of variance showed that high suction water treatment had a significant impact on biological yield.
The average comparison of the data also shows that the application of a high adsorption agent will increase the biological yield.
The maximum biological yield was obtained using a polymer of 45 kg/ha (2761 kg/ha)
And the minimum rate of return accumulated in control (1919kg/ha)
This indicates an increase in production by increasing aggregate consumption to 30. 5 % (Figure 2). Grain yield (economic yield)
The results showed that the effect of irrigation intervals and superabsorbent polymers on yield was significant at a probability level of 1%.
The average comparison showed that the irrigation interval effect of watering for 10 days and 15 days was 1087 and 78, respectively.
8 kg/ha, 31 respectively.
The difference in food production was 39%.
Using a 1019 kg/ha high water absorbent polymer, the most average grain yield was 45 kg/ha, and the least was 688 kg/ha observed in control treatment (Table 1). The 32.
49% as compared to the control treatment, the difference between the two treatments increased with the use of superabsorption.
Harvest index: gain index by dividing grain output by biological output multiplied by 100.
Analysis of variance shows that irrigation intervals have a significant impact on the harvest index, and the increase in drought stress reduces the harvest index, making the harvest index of the 10-day irrigation interval (43. 91)was 26.
63% irrigation intervals over 15 days (Table 1).
The same results were found in other studies of mung beans [6].
Protein percentage: protein percentage is one of the quality features with special value in beans.
The results showed that irrigation intervals, high water absorption polymer consumption and the percentage of proteins significantly affected by their interactions.
An increase in moisture loss increases the percentage of grain protein (Table 1).
Dehydration such as high temperature will increase protein, so the application of irrigation intervals in breeding causes the greatest pressure on mung beans.
Increase the number of dry stress grains and 1000-
The grain quality is reduced, so more nitrogen belongs to the grain, and the percentage of grain protein increases.
Mung bean protein is greatly affected by environmental conditions.
These changes vary greatly between different genotypes, so seed proteins in 6 environments vary from 23. 59% to 27.
49% and 7 gene types, with an average of 24.
Of the 20 genotypes, a higher proportion of protein was 85% [7].
The results of the ANOVA showed that irrigation intervals and super absorbent polymer consumption and the interaction between them had a significant effect on the percentage of seed proteins (Figure 3).
The highest protein content occurs in 15 days (22. 23%)
Comparison of irrigation intervals 5 (5. 94%)and 10 (20. 29%)day intervals.
The average comparison of the dosage of high water absorbent resin shows that the average dosage of protein in 45 kg/ha is more than 11.
Compared with control treatment, 18% (Figure 4).
