e0“Two field experiments were conducted at the Experimental Farm of El-Sirw Agricultural Research Station, Dammietta Governorate, Egypt, in 2007 and 2008 seasons, to study the effect of phosphorus rate (0, 18, 36, and 54 kg P2O5/ha) and Zinc rate (0, 12, 24 and 36 kg ZnSO4/ha) on productivity of some rice cultivars (Giza177, Giza 178 and Sakha104 as inbred cultivars and hybrid cultivar SK2034H) under saline soil conditions.”
e5“There were no significant differences in plant height among phosphorus rates in the two seasons of study.”

Other claims from this paper (19)
- Association SK2034H was superior to other cultivars in leaf area index, dry matter production and number of tillers/m2 in both seasons.
- Association SK2034H was superior to other cultivars in number of panicles/m2, panicle length and number of filled grains/panicle in both seasons.
- Association SK2034H was superior to other cultivars in grain yield, straw yield and harvest index in both seasons.
- Association SK2034H was superior to other cultivars in nitrogen, phosphorus and protein content of grains in both seasons.
- Association SK2034H was superior to other cultivars in plant height, only in the second season.
- Association Giza 177 gave the heaviest 1000-grain weight among the cultivars.
- Association Increasing phosphorus rate from 0 to 36 kg P2O5/ha significantly increased leaf area index, number of tillers/m2, number of panicles/m2 and panicle length in the two seasons.
- Association Increasing phosphorus rate from 0 to 36 kg P2O5/ha significantly increased panicle weight, number of filled grains/panicle, grain yield and harvest index in the two seasons.
- Association Application of 54 kg P2O5/ha gave the highest dry weight, 1000-grain weight, straw yield and N, P and crude protein contents of grains.
- Association Increasing zinc rate from 0 to 36 kg ZnSO4/ha significantly increased leaf area index, dry matter production and panicle length.
- Association Increasing zinc rate from 0 to 36 kg ZnSO4/ha significantly increased panicle weight, 1000-grain weight and grain yield.
- Association Increasing zinc rate from 0 to 36 kg ZnSO4/ha significantly increased straw yield, harvest index and N and crude protein contents of grains.
- Association Increasing zinc rate reduced unfilled grain percentage and phosphorus content of grains.
- Intervention effect Applying 24 or 36 kg ZnSO4/ha, compared with no zinc fertilizer, increased tillers/m2, panicles/m2 and filled grains/panicle, not significantly.
- Association Zinc fertilizer rate had no significant effect on plant height in both seasons.
- Association The first and second order interactions of phosphorus and zinc rates and cultivar had significant effects on grain yield.
- Association The maximum grain yield of SK2034H was obtained with 54 kg P2O5 + 36 kg ZnSO4/ha or 36 kg P2O5 + 24 kg ZnSO4/ha in the two seasons.
- Association Giza 178 and Sakha104 gave the highest grain yield with 36 kg P2O5 and 36 kg ZnSO4/ha.
- Recommendation Sowing SK2034H with 54 kg P2O5/ha and 24 or 36 kg ZnSO4/ha could be recommended for optimum grain yield under saline soil.
