The Effect of Irrigation Interval and Different Doses of Zeolite on the Growth and Yield Indices on White Bean (Phaseolus lanatus L.)
Journal Title: Iranian Journal of Pulses Research - Year 2024, Vol 15, Issue 1
Abstract
IntroductionThe increasing demands for pulse crops and the lack of water resources in most parts of Iran, especially in dry areas, need to employ new strategies to increase water productivity of pulse crops. One of the new methods in managing water and soil resources is the use of zeolite as a storage tank, which prevents wastage and increases the efficiency of irrigation water particularly in light soils. The purpose of this research was to determine the effect of different amounts of zeolite and irrigation interval on growth and yield indices in Pak cultivar of white beans (Phaseolus vulgaris L.). Materials and MethodsThis research was conducted in order to investigate the effect of different amounts of zeolite and irrigation interval on the growth and grain yield in Pak cultivar of white bean (Phaseolus vulgaris L.), in a split plot design based on randomized complete block design with three replications in a farm located in the bojnord city - north Khorasan in the agronomic year 2023-2024. The study factors included 7, 10 and 13 days irrigation interval in the main plot and three levels of zeolite in the soil (0 (no use), 5 and 10 t.ha-1) in the sub plots. Data were analyzed using SAS 9.4 statistical package and figures were drawn by Excel program. Mean comparison were arranged by least significant differences in the 95% probability. Results and DiscussionThe results revealed that the white bean plants attained their shortest height across all three irrigation levels when zeolite was not applied in the plots. Conversely, when a zeolite level of 10 t.ha-1 was introduced, there was an observed increase of 18.15% in the number of nodes per plant compared to scenarios where no zeolite was utilized. The highest level of zeolite consumption caused an increase of 13.88% in the seed weight compared to the level of no zeolite consumption. The highest seed yield of 4651.5 kg.ha-1was recorded in the 7 day irrigation interval and zeolite consumption of 10 t.ha-1. The lowest amount of electrolyte leakage related to irrigation interval of 10 and 7 days and consumption of 10 t.ha-1 of zeolite was 14.8 and 12.34%, respectively. The consumption of 10 t.ha-1 of zeolite caused a 21% increase in protein compared to the non-use of zeolite in white beans, and with the increase of the irrigation frequency from 7 to 10 days, although the amount of seed protein decreased, it did not have a significant difference with the level of irrigation once every 7 days. And when the irrigation cycle reached once every 13 days, the amount of seed protein decreased significantly by 6.8% compared to the irrigation cycle once every 7 days. It was also found that the addition of 10 tons of zeolite per hectare to the soil caused a 41.5% decrease in the amount of proline in white bean leaves compared to the absence of zeolite. In this research, it was found t.hat the level of 10 t.ha-1 the highest biological yield of 13475 kg.ha-1 recorded and it increased by 29.2% compared to the no zeolite consumption. By reducing the irrigation interval to 10 and 7 days, with the increase of zeolite consumption, the harvest index increased, and in the meantime, the highest index related to the irrigation cycle of 7 days and zeolite consumption of 10 tons was 35.5%. ConclusionsBased on the obtained results, it can be concluded that water stress resulted in a reduction in the growth characteristics and overall performance of white bean plants. The lowest values ââof parameters calculated in this research were observed at the level of no zeolite consumption and irrigation cycle of 13 days, and their highest values ââwere observed at the level of zeolite of 10 t.ha-1 and irrigation cycle of 7 days, which shows that Zeolite, help more water absorption and water return when the plant needs water, and increase the growth of different plant tissues and production of more products. Overall, it can be inferred that applying zeolite at a rate of 10 t.ha-1, particularly in conjunction with a 7-day irrigation cycle, can optimize the yield and growth characteristics of white beans, specifically the Pak cultivar. However, we recommend further investigation into higher levels of zeolite application across various soil textures to enhance our understanding and refine cultivation practices.
