The effect of type and amount of natural zeolite on yield and yield components of millet (Panicum miliaceaum L.)
Journal Title: Journal of Agroecology - Year 2023, Vol 15, Issue 2
Abstract
IntroductionIn recent years, due to the excessive consumption of agricultural inputs, especially chemical fertilizers and common methods of crop production, problems have arisen that have led to more attention to sustainable agriculture.Zeolite is one of the natural minerals that also has nutritional value and can be considered a step towards achieving sustainable agriculture.Materials and methodsIn order to investigate the effect of type and amount of zeolite on the yield of common millet, an experiment was conducted in the crop year of 2017-17 at the research farm of the Faculty of Agriculture of Birjand University. This factorial experiment was performed using randomized complete block design with 3 replications. Experimental treatments included two types of calcium and potash zeolites in two forms of powder and granules, which were considered at two levels (5 and 10 tons per hectare) with a control treatment without zeolite. In this study, common millet (Pursu) was used for cultivation.Results and discussionNumber of clusters per plant: Analysis of variance of data showed that the effect of treatment on this trait was not statistically significant at the level of 5% probability. However, the control treatment had fewer clusters than the potassium powder and granular treatments of 10 tons per hectare and the calcic powder and granule treatments of 10 tons per hectare. Also, the control treatment had more clusters than the calcium granular and powder treatments of 5 tons per hectare and the potassium granular and powder treatments of 5 tons per hectare. Comparison of the average effect of zeolite content on the number of clusters per plant showed that increasing the application of zeolite from 5 tons per hectare to 10 tons per hectare caused a significant increase in the number of clusters per millet plant at a probability level of 5%.Thousand-grain weight: Analysis of variance of 1000-grain weight data as a treatment, to compare with the zeolite control treatment showed that the effect of zeolite treatment on millet 1000-grain weight was significant at 5% probability level. The results of factorial analysis of variance showed that the simple effect of zeolite type on 1000-grain weight was significant at 5% probability level. But the simple effect of zeolite content as well as the interaction effect of type and amount of zeolite on this trait was not significant.Grain yield: The results of analysis of variance of grain yield data to compare treatments containing zeolite with control treatment without zeolite showed that the effect of zeolite treatment on grain yield was significant at the level of 1% probability. The results of factorial analysis of variance showed that the simple effect of zeolite content at 1% probability level and the effect of type and amount of zeolite at 5% probability level on grain yield were significant. But the simple effect of zeolite type had no significant effect on this factor. The results of comparing the average amount of zeolite on grain yield showed that increasing the amount of zeolite increased millet grain yield at a probability level of 5%.Water use efficiency: The results showed a significant effect of zeolite treatment on water use efficiency at a probability level of 1%. The results of variance for water use efficiency showed that this trait was significantly affected by the simple effect of zeolite content and the interaction between type and amount of zeolite at 5% level but the effect of zeolite type on it was not significant. The results of comparing the average amount of zeolite on water use efficiency showed a statistically significant difference between the application of 5 and 10 tons per hectare of zeolite at the level of one percent.ConclusionThe results showed that the application of different types of zeolite caused a significant increase in 1000-grain weight and number of grains per panicle at a probability level of 5% and grain yield, water use efficiency at a probability level of one percent compared to control treatment (no application of zeolite). Increasing the application of zeolite from 5 to 10 tons per hectare significantly increased the number of spikes per plant, number of seeds per spike, 1000-seed weight, biological yield, grain yield and water use efficiency. Therefore, with the optimal using of this fertilizer, the effects of drought stress on plants are somewhat reduced and it is recommended for using in dry areas.
