Abstract:
In order to investigate the effects Azoto of irrigation cutting and chemical and biological fertilizers, Azoto Barvar 1 and phosphate Barvar 2 on grain yield, essential oil and biochemical properties cumin, an experiment was conducted as split plot based on a randomized complete block design with three replications at the University of Zabol Research Farm during 2016. Main plots included four levels of irrigation cutting; conventional irrigation, irrigation cutting in between stem elongation to flowering, irrigation cutting in between flowering to beginning of the grain filling period and irrigation cutting in between beginning to end of grain filling period. The subplot was the different type of phosphorous fertilizer including control (no fertilizer application), Azoto Barvar 1 and Phosphate Barvar 2 and triple superphosphate. Results indicated that the interaction of irrigation cutting and phosphorous fertilizer was significant on seed yield, oil percentage, carbohydrates, proline, total protein, absorption of nitrogen, phosphorous and potassium. The greatest seed yield, oil percentage, total protein, nitrogen, potassium and phosphorus obtained at conventional irrigation along with the application of Azoto Barvar 1, while the greatest proline was achieved at irrigation cutting between beginnings to the end of grain filling period along with the application of triple superphosphate. The greatest carbohydrate was observed at irrigation cutting between beginnings to the end of the grain filling period along with the application of Phosphate Barvar 2. In conclusion, results indicated positive effects of biofertilizers on the improvement of nutritional conditions of plants under irrigation cutting conditions
