In general, most plants grow by absorbing nutrients from the soil. Their ability to do this depends on the nature of
the soil. Depending on its location, a soil contains some combination of sand, silt, clay, and organic matter. The
makeup of a soil (soil texture) and its acidity (pH) determine the extent to which nutrients are available to plants.
This experiment was carried out at in two location with rich soil farm at Rice Research Institute of Tonekabon and
poor soil farm at Ramsar, Mazandaran, Iran in 2012, as split split plot in randomized complete blocks design based
three replications. Macro element in five levels {M1: NPK, M2: PK, M3: NK, M4: NP and M5: 1/3 NPK} was chosen
as main plots, Micro elements in two levels as sub plots {N1: Mn-Zn-Si and N2: non application} and cultivars as
sub sub plots including line 843 and cv. Shiroodi. The results showed that the most panicle length and number of
filled spikelet per panicle were as noted for M1. Number of filled spikelet per panicle in Line 843 more than cv.
Shiroodi. At double interaction of L*C the most number of filled spikelet per panicle was observed at interaction of
L1C1 and L2C2. As, at double interaction of N*C the highest number of filled spikelet per panicle had obtained at
N1C2. Grain width in Line 843 more than cv. Shiroodi. At triple interaction of L*M*N the maximum grain width had
shown at L1M3N2. The maximum grain yield equivalent to 6499.2 and 6433.8 kg/ha was produced in M1 and M2.
Grain yield in Line 843 because of increase number of filled spikeler per panicle, grain length and grain width more
than cv. Shiroodi. At double interaction of L*M the most grain yield was produced at interaction of L2M1 and L2M3.
As, at double interaction of N*C the highest grain yield was obtained in N2C2. At triple interaction of L*N*C the
most grain yield had produced in L2N1C2 and L2N2C2, as the least grain yield in this interaction had observed at
L1N1C2 and L1N2C1. At double interaction of M*C the most harvest index was observed at M4C1, M4C2 and M5C2,
respectively.
