Abstract

Analysis of the effect of drought stress and Humic Acid organic fertilizer and Nitroxin Biofertilizer on the features such as 100 seeds weight, plant height, the amount of a and b chlorophyll and cartenoids of pea crop (Cicer arietinum) an experiment was conducted in case of split split-plot in the frame base design of completely randomized blocks in 3 replications in Dehbakri zone of Bam city in 2013-2014. Experimental factors were considered in 2 dry levels such as (6 days irrigation, without stress) and (9 days irrigation, stress) and Humic Acid organic fertilizer at 2 levels such as non-use of Humic Acid and use of Humic Acid in the amount of 100 kg per hectare and nitroxin biofertilizer at 2 levels such as non-inoculation of fertilizer and inoculation of fertilizer in the amount of 2 liters per hectare. Parameters studied were 100 seeds weight, plant height, a and b chlorophyll pigments amount and cartenoids. The results showed that drought, Humic Acid organic fertilizer and Nitroxin Biofertilizer have significant effect on the studied features. The amount of increasing dry level of 100 seeds weight, plant height, a and b chlorophyll decrease, the amount of cartenoids will increase with the increase of level stress, and also by using the organic and biological fertilizer all features showed increasing and significant effect and the interaction of treatments with each other showed significant effect on the different features.
