This factorial experiment carried out in the research field in Al-
Mussaib technical college during 2018-2019 with the aim of increasing
the qualitative and chemical growth parameters of the vinca
plants cultured in plastic pots by the effect of adding different ratios
from bokashi (0, 10, 20, 30 and 40%) from pot weight. While the
second factor was use and don’t use the Azosperillium bio fertilizer.
The experiment was designed according to C.R.D. of five replicates
for each treatment, each replicate contains five pots. The results
showed that the study factors had a significant effect on the all studies
characteristics, the interaction (30% bokashi with Azosperillium)
gave highest levels of the leaves content of (Chlorophyll 42.48
SPAD, N 2.684%, P 0.402%, K 1.38% and carbohydrates 5.094 %)
and the number of branches roots 30.2 root, also the interaction (40%
bakashi with Azosperillium) gave the highest rate of root length
31.4cm. While the plants of control treatment showed a significant
increase in the leaves content of proline acid 1.17gm.L-1

Factorial trail was conducted out at Al-Watifiyah region 40 km
northern Babylon in winter agricultural season 2018 with the aim of
knowing the effect of bio-fertilizers and phosphate fertilizers in terms
of vegetative and flowering growth of fennel plant(Foeniculum vulgare
Mill), where factorial experiment was applied to Randomized
Complete Block Design (R.C.B.D) with three replicates, The first
used factor were included the use of four levels of bio-fertilizers,
(without addition, mycorrhiza, and Azotobacter spp , Mycorrhiza
+Azotobacter spp). Second factor was the use of four levels of phosphate
fertilizer P2O5 (0, 40, 60 and 80 kg.ha-1). Data were collected,
statistically analyzed, and arithmetic averages were compared according
to the LSD test, the probability at the level of 5% . Showed
that the bio-fertilizers had a results significantly effect on the studied
traits, where treatment of Azotobacter bacteria and added phosphorus
of 60 kg.ha-1 excelled and giving the highest average plant height
(159.67 cm), number of vegetable branches (15.0 branch.plant-1), dry
weight of the vegetative growth (12.92 g) . While the interaction of
Mycorrrizae and the adding the phosphorous at 60 kg.ha -1 achieved a
significant increase in the number of umbel (12.67 umbe.plant-1), the
number of umbellate per umbel (9.67 florets. Inflorescence-1), the
1000 grains weight (10.0 g), total fruit yield (1.83 tons.ha-1) while the
control treatment gave the lowest average of all studied traits.

The present study was conducted to determine the feeding preferences
of grass carp (Ctenopharyngodon idella) for three aquatic
plants : water fern (Azolla filiculoides), duckweed (Lemna spp.) and
water hyssop (Bacopa monnieri), in two different water temperatures
(22-24 and 27-29 oC ) for the period from 30 Oct.2019 to 12 Dec.
2019. Water hyssop were neglected from the second temperature experiment
since no plant consumed in the first trail. The average fish
weight in 22 -24 oC was 91.85±12.59g and in 27-29 oC was
89.19±16.18g. Mean daily feeding rates (DFR) of grass carp from
water fern and duckweed were not significantly different (P>0.05),
but both plants were eaten in significantly (P<0.05) greater quantities
than water hyssop plant which was not eaten by grass carp. The consumed
plants were 48.00 and 39.77% Body Weight/day from water
fern and duckweed in temperature 22-24 oC, while in 27-29 oC it
was 47.19 and 41.83 % Body Weight /day respectively. It was concluded
from the present study that grass carp equally prefer water
fern and duckweed but not water hyssop; this may be associated with
the nature of and leaves structure.
