EFFECT OF SOME AGRICULTURE TREATMENTS ON YIELD PRODUCTIVITY OF SQUASH

Abstract

Two filed experiments were conducted _ The first was performed in summer season to evaluate the productive characteristics of three squash cultivars (Obodas, hybrid, Arlika hybrid, Esbndmani) that fertilized through five systems (I OO%mineral fertilizer, I 00% biogas fertilizer + salicylic acid (SA) sprays +SO% mineral fertilizer +50% biogas+ GE )IOO%covers 60kg N/fed _ The second, in winter, season , dealt with the effect of seed vernalization (non or vernalized )and fertilization system (!00% biogas fertilizer, 50% biogas+SO%, mineral fertilizer and I 00% mineral fertilizer, 50% cultivars (Eskandarani and Arlika hybrid productive characteristics_ Each experiment was conducted in two successive seasons _ Summer squash experiment showed that the most productive cultivars was Arlika hybrid and the most pronouncing fertilization system was that contained 100% biogas fertilizer +GE. Winter squash experiment favoured that of Arlika hybrid , seed vemalization and 100% biogas fertilizer in gcnral.
