To understand the effect of phosphorous fertilizer on the function and functioning components of “Brassica napusl (B.N.)” Hayola No. 401 in rain fed agriculture in different groups of phosphorous soil fertility 16 tests in 4 different areas have been conducted and in each area 4 tests in 4 groups of phosphor usable in the soil ( less than 3 ppm, 6-10 ppm and more than 10 ppm) in the form of blocks have been done completely randomly in 4 different fertilizers treatment ( 0, 25, 50, 75, kilo grams of p2o5 in hectare). Triple super phosphate resources have been used in 4 repetitions for two agricultural years (2018-2019). Results obtained show that phosphorous fertilizer treatment in all groups of fertilizing soil have no meaningful effect on the seeds functioning, number of saddlebags, number of seeds in the saddlebag, weight of each 1000 seeds.

“Brassicsa napusl” is oil producing plant which plays important role in the human nutrition with its oil production, and it also has an important role in the food for animals and birds . This plant contains more than 40% oil in its seeds and about 40% protein in its meal and that is why this plant is considered very important [2-4]. High amount of oil contamination in canola and also suitable corrected acidic fat mixture cause its dominance in the world market. Since, more than 90% of the country’s eating oil is imported from abroad, therefore it is important to value this plant . Sandhu, et al.  reported in their research shortage of phosphor caused stop in the growth and formation of reproductive organs and grows very slowly and therefore the plant is short in branches and the number of saddles, weight in every 1000seeds. MaJumdar and Sandhureported that the phosphor fertilizer in the number of seeds in saddle, weight of 1000 seeds has been increased a little but their results did not have any effect in the increase of the functioning. Holmes, et al. [6-7] showed in their research that phosphorous seeds very rarely have high effects on the rape seed’s function and the height of this effect depend on the amount of phosphor in the soil. In Indian soil it has been reported that the phosphorous fertilizers have positive reaction on the functioning and functioning component but its 3effect is little [5,8- 10]. Sajed, et al.  in an analysis on the Zucchini with thin layer seeds reported that using of phosphorous fertilizer caused increase in the number of lateral shoots, functioning, number of fruit and the amount of seeds production.
Materials and Methods
The test has taken place in Behbahan in southeast of Khozistan state with the longitude 12`, 15° east and latitude of 36`, 30° north and the height of 320 meters from the sea level. Behbahan is an area with semi deserted climate which located in hot steppe climate. Average of rainfall and 10 years temperature is equal to 313.5 milli meters and 25 degrees centigrade respectively. To understand the effect of phosphorus fertilizer on the functioning and sub functioning of component of canola in the rain fed agriculture in different groups of soil phosphorous fertilizing, 16 tests have been conducted in 4 areas. In each area 4 tests in 4 groups of phosphors usable in soil (less than 3ppm, between 3-6ppm, between 6-10ppm and more than 10ppm) have been repeated in 4 treatments of phosphorous fertilizer in the form of complete random block (0, 25, 50, 75 k.g. p2 o5 in hectare) from the triple super phosphate. It means that in each group of soil fertilizing by the amount of phosphate used in the soil for test in the form of complete random block plan in 4 treatments of phosphoric fertilizer in 4 repetitions. The space between these 4 areas are about 35 to 50 kilo meters and the space from the fields to each area was between 3 to 5 kilometers therefore each test consists of 16 terraces. Each terrace with the length of 5 meters with 8 implant lines with 30 centimeters space between them and the space between the bushes on each row was 5 centimeters, the space of terraces in relation to each other in each side was 1.5 meter and the repetitions space also was 1.5 meter. The date of implanting was fixed on the date of the first rainfall in the autumn in the area. Hayolla 401 was used in the test. Method of cultivation was serial and the amount of used seeds was 8 kilograms in hectare. In all the treatments 60kg/ha pure nitrogen (1/2 base +1/2 at the time of shooting (stemming) from the urea source and 50 kilograms of K2 O in each hectare from the potassium sulfate were used as the base. Gain for removal after ripening of saddlebags from an area equal to (1.5*4 meters or 6 meters) from each terrace was done and seed’s functioning has been determined at the moisture of 10%in hectare. The numbers of bushes in unit, number of seeds in saddlebag, number of saddlebag in bush in unit and the weight of one thousand seeds were measured. In this research MSTAT software was used for statistical analysis. Comparisons of averages have been conducted according to LSD test. Variance analyses of 2 agricultural years have been conducted according to composite variance analysis.
Results and Discussion
Functioning and Functioning Components
Results of composite variance analysis of 2 agricultural year on the functioning and functioning components showed less than 3 percent ppm in the fertilizing group of phosphorous soil which shows that the effect of phosphorous fertilizer’s treatment on the seed, saddle, number of seeds in the saddle and weight of 1000 seeds isn’t meaningful but the mutual effect (area *fertilizing group) on the seed functioning is meaningful (Table 1). Results obtained from (Table 2) for comparison of fertilizer treatment with witness treatment according to “LSD” test show that there isn’t a meaningful difference through the seed functioning, number of saddle, number of seeds in saddle and thousand seeds weight between witness treatment with the fertilizing and all are located in one group. In 3-6 ppm soil phosphor of fertilizing group, effects of phosphorous fertilizer treatment on the seed functioning, number of saddles, number of seeds in a saddle and weight of 1000 seeds could be found which was not meaningful. The mutual effect (phosphorous fertilizer * fertilizing group) of this group on the seed functioning is meaningful but, on its components, it isn’t meaningful and mutual effect (areas * fertilizing group) on the seed functioning is meaningful (Table 3). According to LSD test there isn’t a meaningful difference between phosphorous fertilizer treatments with phosphorous fertilizer with witness treatment (Table 4).
Note: The effect treatment no significant for properties no mention amount (L.S.D).
The composite variance analysis in phosphorous fertilizer treatment absorbable in the soil during two years showed ppm of between 6 to 10. The effect of phosphorous fertilizer treatment and the mutual effect in this group (phosphor fertilizer * fertilizing group) on the functioning and its components was not meaningful. But mutual effect (areas * fertilizing group) on the seed functioning was meaningful. On one hand according to LSD test there wasn’t a meaningful difference between fertilizing treatments with witness treatment in the group. (Tables 5 & 6). In phosphorous soil of fertilizing group of more than 10 ppm results of composite variance analysis for two agricultural years were shown. Phosphorous fertilizing treatment and their mutual effect (phosphor fertilizer * fertilizing group) on the seed’s functioning was meaningful. (Table 7). Results of table 8 show that there isn’t a difference between phosphorous fertilizing treatment with a witness treatment according to LSD test. Considering the results of the test, it can be said that phosphorous fertilizer very rarely have much effects on the seed functioning of Brassica napuls. on the other hand, some of the soil specifications such as organic materials, moisture and the amount of phosphor absorbable in the soil are effective. In the soil with higher amount of organic materials and more suitable moisture the functioning is difference in relation to witness treatment even though it isn’t meaningful.
Note: The effect treatment no significant for properties no mention amount (L.S.D).
The amount of phosphor absorbable in soil in group of (3-6)
and (6-10) ppm in relation to phosphor group absorbable (less or
very high) has suitable effect on the seed functioning. In some of
the soil phosphor fertilizing group (medium or high), the amount
of fertilizing phosphor, number of saddles and weight of 100 seeds
increases a little but their 3effect on the seed functioning is not
enough in research on the Brassica napuls plant it has been reported
that phosphorous fertilizer does not increase the seed functioning
but the height of the plant, number of intial subshrubs and number
of saddles will increase a little and also the phosphorous fertilizer
has no effect on the number of seeds and weight in 1000 seeds.
Mojumdar and Sandhu  reported that phosphorous fertilizer increases the number of seeds and weight of 1000seeds a little.
But their results have no effects on the increment of seed function.
Holmes and AInseley [7-8] mentioned that the phosphorous
fertilizer very rarely causes effects on the B.N seed functioning and
its effect depends on the amount of phosphor in the soil.
In India regarding the effect of phosphorous fertilizer on the function and its components no positive reaction was noticed. The reason for it is due to the soil condition. Singh, et al [9-14] regarding Indian soil reported that the phosphorous fertilizers have positive effect on the functioning and its components, but it is a little. On research on the medical plant of paper seed pumpkin reported that more phosphorous fertilizer showed the number of seeds in the bush, weight of dried seed in bush and maximum weight of dried seed in each square meter. Also, the use of phosphorous fertilizer causes increase in the number of lateral shoots, functioning and the number of fruit and amount of medical pumpkin seed’s production [1,15].
Different treatment of phosphorous fertilizer in all groups of soil phosphorous fertilizing have no meaningful effect on the functioning and functioning component of B.N. (number of saddles, number of seeds in the saddle and weight of 1000 seeds.
