Abstract
Introduction
Increasing the yield of agricultural products per unit area is very important for preparing the food needed by the growing population of the country. One of the solutions is to add fertilizers in different forms and compositions to the soil to increase crop yield and strengthen soil fertility. Far away has been common all over the world.
Materials and Methods
In order to investigate the effect of different levels of camel manure and manganese sulfate on growth and yield and yield components of Setaria italic, a factorial experiment in the form of a randomized complete block design with three replications in 2009-2010 in Abuzar well cultivated lands. Khosf city was implemented. Experimental treatments included: camel manure at three levels (0, 10 and 20 t / ha) and manganese sulfate at four levels (0, 30, 60 and 90 kg/ha).
Results and Discussion
The results of statistical analysis of the data showed that different levels of manure and manganese sulfate and the interaction between them had a significant effect on biological yield, number of grains per panicle and grain yield. So that the highest values of the above indices were observed in the treatment of manure 20 tons per hectare and 90 kg per hectare of manganese sulfate. The highest and lowest number of panicles were obtained in the treatment of 20 tons of camel manure and the application of 30 kg/ha of manganese sulfate and the control treatment without the use of camel manganese and manganese sulfate. The length of the panicle was also affected by the main effects of manure and manganese sulfate. So that the maximum panicle length was obtained in the treatment of 20 tons per hectare of manure and the treatment of 90 kg per hectare of manganese sulfate. The effect of manure levels on number of tillers per plant, number of spikes per plant and number of plants per square meter was significant, but other effects had no significant effect on these traits and the highest number of tillers per plant, number of spikes per plant and number of plants In the treatment of 20 tons per hectare of camel manure were obtained per square meter. The main effects of different levels of manure and manganese sulfate at the level of one percent probability had a significant effect on 1000-grain weight and millet harvest index, but the interaction of these factors did not have a significant effect on these traits. The highest 1000-seed weight was observed in the treatment of 20 tons per hectare of camel manure and the treatment of 90 kg per hectare of manganese sulfate. Also, the highest harvest index was related to the treatment of 20 tons per hectare of camel manure and also the highest harvest index was obtained from the consumption of 60 kg per hectare of manganese sulfate.
Conclusion
Finally, it can be concluded that the best treatments in this experiment were the use of 20 tons per hectare of camel manure and 90 kg per hectare of manganese sulfate. In fact, manure improves plant growth by gradually providing elements and using micronutrients. The use of manure is one of the appropriate solutions to achieve ecological agriculture that can increase agricultural production and due to the fact that most of the soils of South Khorasan province are calcareous and manganese deficient, the use of this element can be Help to remove this limitation and increase plant yield.
