Abstract
A field experiment was conducted at Students` Instructional Farm at Afghanistan National Agricultural Science and Technology University, Kandahar (ANASTU) Afghanistan during winter season of 2014-15 to study the effect of phosphorus levels on growth and productivity of wheat (Triticum aestivum L.) varieties. The treatments consisted of two varieties of wheat viz. Shashambagh-08 and PBW-154 and five phosphorus levels viz.0, 40, 60, 80 and 100 kg P2O5/ha which were evaluated in factorial randomized block design with 3 replications.
A field experiment was conducted at Students` Instructional Farm at Afghanistan National Agricultural Science and Technology University, Kandahar (ANASTU) Afghanistan during winter season of 2014-15 to study the effect of phosphorus levels on growth and productivity of wheat (Triticum aestivum L.) varieties. The treatments consisted of two varieties of wheat viz. Shashambagh-08 and PBW-154 and five phosphorus levels viz.0, 40, 60, 80 and 100 kg P2O5/ha which were evaluated in factorial randomized block design with 3 replications.
Results revealed that maximum and significantly higher growth and yield attributes viz. plant height, dry matter accumulation, leaf area index, number of tillers per square meter, length of spike, number of grain per spike, grain weight per spike, and1000-grain weight were recorded higher with Shashambagh-08, grain yield (3.53 t ha-1), straw yield (4.85 t ha-1) and biological yield (8.36 t ha-1) were also recorded significantly higher with Shashambagh-08 variety, but spikes per square meter and harvest index were registered higher in PBW-154.
Phosphorus levels significantly increased growth parameter up to 100 kg P2O5 but were at par with 60 kg P2O5 and 80 kg P2O5. With successive increase in levels of phosphorus significant increase plan height, dry matter accumulation, leaf area index number of tillers per square meter, length of spike, number of grain per spike, grain weight per spike, 1000-grain weight, grain yield, straw yield and biological was recorded only up to 60 P2O5/ha. However, maximum number of tillers per square meter, length of spike, number of grain per spike, grain weight per spike, 1000-grain weight, grain yield, straw yield and biological was recorded with 60 kg P2O5/ha.
It is conclude from the study that variety Shashambagh-08 is more productive and respond to phosphorus application up to 60 kg P2O5.
