Abstract
Investigation of the effect of planting density and different levels of iron fertilizer on the yield and yield components of rapeseed Hyola 401
In order to investigate the effect of plant density and different levels of iron fertilizer on the yield and yield components of rapeseed Hayola 401 in 2018, a split plot experiment was carried out in the form of a randomized complete block design with three replications in an area located 2 km from Noorabad Mamsani. The factors investigated were: plant density at three levels (30, 50 and 70 plants per square meter) The main plots and different levels of iron fertilizer at three levels (1x1000), (2x1000) and (4x1000) as sub-factors in the sub-plots. The attributes evaluated include the number of pods per plant, the number of seeds per plant, the number of pods in the main and secondary branches, the height of the plant, the weight of one thousand seeds, oil yield and oil percentage per unit area, which are the results of the statistical analysis of the data that was done using the spss method. It showed that both the effect of planting density and the effect of different levels of iron fertilizer on all investigated traits had a significant difference at the 5% probability level, that the highest seed yield among the interaction effect of planting density and iron fertilizer level is related to the density of 70 plants per square meter and the level of iron fertilizer (1000 x 4). In general, based on the obtained results, the planting of Hayola 401 rapeseed with a density of 70 plants per square meter and the level of iron fertilizer (4x1000) is recommended for fall cultivation in Noorabad Mamsani region. rtl;">
Introduction
Many years ago, the great European theorist Malthus stated that in contrast to the geometric exponential growth of the population, the growth of agricultural production has an exponential exponential trend, and he predicted the occurrence of famine and the consequences related to it for humanity, although today it seems that his predictions were not very accurate, but the obvious and hidden hunger in human societies cannot be hidden. If the current growth rate of the population, especially in third world countries, is not adjusted, in the near future we will witness a human disaster of widespread death due to hunger, and the desire for self-sufficiency is the ultimate goal of agricultural planning in all countries of the world, especially third world countries (Rastegar, 1377). All scientific, research and executive levels and assemblies of the country, but it must be acknowledged that our country has a long way to go before achieving self-sufficiency in all agricultural products, and now there is a large need for imports in products such as oilseeds, sugar, and corn (Hikaritnia, Rajaee 1387). The country's annual edible oil production is estimated to be about one million tons, while domestic production meets only 10% of this need, and more than 90% of the country's edible oil is imported from abroad with an amount of over 500 million dollars. In order to reduce the financial burden of importing edible oil and increasing domestic production in recent years, the authorities of agriculture have paid increasing attention to the planting and exploitation of oil plants. rapeseed cultivation has been considered (Hikaritnia, Rajaee 1387).
Due to the amazing growth of science and development of technologies in all fields of applied sciences, including agriculture, we are witnessing an increase in production per unit area day by day, and through globalization and the creation of the global village and the expansion of trade exchanges and the membership of most countries in the World Tariff and Trade Organization (GAT), of course, farmers will be successful in being able to maximize production per unit area. with minimum cost.One of the most important factors in achieving this result is the correct use of agricultural inputs such as chemical fertilizers. Chemical fertilizers, both in terms of having a major contribution in increasing production, and in terms of the cost that farmers bear to prepare them, and in terms of observing environmental issues, play a very important role in agronomic and agricultural studies, as well as the review and integration of study materials.
In recent years, a lot of attention has been paid to the development of rapeseed cultivation in order to achieve There has been insufficient production of edible oil in the country, and due to the new nature of this cultivation at the global level and especially in Iran, not many research works have been done on this plant, and on the other hand, every year, new varieties of rapeseed are imported into the country, the potential of producing these varieties in different regions is not known, and it is especially important to check the performance of the varieties in specific climatic conditions. rtl;">

ABSTRACT
INVESTIGATION OF SOWING DENSITY AND DIFFERENT LEVELS OF FE FERTILIZER ON YIELD AND COMPONENT YIELD OF CANOLA CULTIVAR HYOLA 401
for surveying the effect of implant and different surface of iron fertility on canola performance and canola performance hyola number 401 for surveying the effect of sprig aggregation and different surface of iron fertilizer on canola performance hyola 401 in 2007 tentatively in the form of split plat as complete block pattern with three times implemented in area placed in 2km of Nurabad which surveying factors are as follow sprig aggregation in three surface (30,50,70 sprig/m2) as a main factor in main kart and different surface of iron fertilizer (1x1000), (2x1000) and (4x1000) as tributary factor in tributary kart. Measuring characteristic is consisting of the number of sheath in sprig, the number of seed in sprig, the number of sheath in main and tributary branch, the height of plant, the weight of thousand speed oil performance and oil percent in surface unit. which its analyzing statistical result which was done based on spss method shows that both the effect of aggregation of implanting and the effect of different surface of iron fertilizer on all measuring characteristics in probably surface %5 has meaning full difference which the most performance of speed between counter effect of implant aggregation and the surface of iron fertilizer related to aggregation of 70 sprig/m2 and the surface of iron fertilizer is (4×1000). Generally based on giving result, implanting Hyola canola 401 with aggregation of 70 sprig/m2 and iron fertilizer surface (4x1000) for autumn implanting in Nurabad is recommended.
