Abstract
Background and Objectives
The combined use of animal and chemical fertilizers and the use of zeolite in bean farming can have an effective role in reducing the use of chemical fertilizers and helping to provide balanced nutrients. Therefore, this research was carried out with the aim of investigating some biochemical responses and performance of two varieties of red bean with the combination of chemical fertilizer and zeolite.
Materials and Methods
A factorial experiment with three factors based on the randomized complete block design with three replications was implemented in climatic conditions of Azna city in Lorestan province in the spring 2016 and 2017. Cultivar factor includes two cultivars Goli (creeping) and Akhtar (standing); nutritional systems operating at five levels including 100% manure fertilizer, 100% urea, 75% manure with 25% urea, 50% manure with 50% urea, and 25% manure with 75% of urea; and zeolite factor in four levels including non-use of zeolite and consumption of 3, 6 and 9 tons per hectare. Based on the soil test, 100 kg/ha of nitrogen from the source of urea fertilizer and 20 tons/ha of animal manure (rotted sheep manure) were used.
Results
Meanwhile, the highest amount of soluble carbohydrates as well as peroxidase and catalase in shoot was observed from the consumption of manure. By increasing the consumption of zeolite, the plant height and the height of the first pod, the number of seeds per plant, the weight of one hundred seeds, and the yield of seeds, the harvest index and protein yield increased, but the amount of soluble carbohydrates, peroxidase and catalase of shoot decreased. In the levels of triple interaction of cultivar × fertilizer × zeolite, comparison of means showed that the maximum plant height and the height of the first pod from the ground, the number of seeds per plant, the weight of one hundred seedsو and the yield of seeds were obtained in both Goli (79.7 cm, 9.5 cm, 37.8 seeds, 38.4 grams and 2341 kg per hectare, respectively) and Akhtar (70.4 cm, 7.3 cm, 44.3 seeds, 52.4 grams and 2630 kg per hectare, respectively) cultivars from the 50:50 manure:urea treatment and six tons per hectare Zeolite. In Goli cultivar, The highest number of sub-stems (31.5 stems) and number of pods per plant (10.2 pods) from 75:25 manure:urea treatment and six tons per hectare of zeolite;The highest shoot catalase (OD 2.72 micrograms of protein per minute) was obtained from 0: 100 manure:urea treatment and no zeolite consumption; while in Akhtar cultivar, the highest maximum number of sub-stems (26.7 stems) from 100 manure treatment: chemical and nine tons per hectare of zeolite; and the highest shoot catalase (2.12 OD micrograms of protein per minute) from urea treatment and three tons per hectare of zeolite.
The results showed that the highest plant height, the first pod height from the ground, the number of seeds per plant, the weight of one hundred seeds and the seed yield in both Goli (respectively 79.7 and 9.5 cm, 37.8 seeds, 38.4 grams and 2341 kg per hectare) and Akhtar (respectively 70.4 and 7.3 cm, 44.3 seeds, 52.4 grams and 2630 kg per hectare) was obtained from the treatment of 50:50 manure:urea and six tons per hectare of zeolite.
Discussion
In total, the Akhtar cultivar is recommended with the use of 50:50 manure:urea and six tons per hectare of zeolite to achieve the maximum grain and protein yield.
