| Abstract | ||
| This study examined the different rates of both bentonite and vinasse as mineral and organic soil conditioners, in combinations, to improve soil chemical properties which should be reflected on pea (Pisum sativum. L,Variety Master B) productivity during the two winter seasons of 2014 and 2015, on sandy soil under drip irrigation system. The experiment was implemented in Ismailia Agricultural Research Station (latitude, 30o 35' 41.901" N and longitude, 32o 16' 45.834" E). The objective of the work is to study the effect of the treatments for bentonite applied were rates of 2, 4 and 6 ton fed.-1 but vinasse with five rates treatments at 0, 0.25, 0.5, 0.75 and 1.0 ton fed-1,respectively. The obtained results revealed that pH values decreased as affected by applied all treatments compared to control treatment, especially with the gradual concentration increase of vinasse. Conversely, both EC and organic matter values increased with increased rates of vinasse and bentonite, in combination. Furthermore, data indicated that values of soil availability nitrogen, phosphors and potassium rise with high rates of bentonite and vinasse as combination compared to control treatment. Moreover, evaluation of pea yield (pods, seeds, straw), as affected by treatments, revealed an increase in yield components. Similar trend was found with total content of macronutrients in pea crop (straw and seeds) in both two studied seasons. Finally, the combination of bentonite and vinasse, working together as mineral and organic soil conditioners respectively, improved the chemical properties of sandy soil, which reflected on the developed pea plant. | ||
