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.”
e3“Increasing phosphorus rate from 0 to 36 kg P2O5/ha significantly increased leaf area index, number of tillers/m2, number of panicles/m2, panicle length, panicle weight, number of filled grains/panicle, grain yield and harvest index in the two seasons.”

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 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 Phosphorus rates had no significant effect on plant height in the two seasons.
- 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.
