The effect of increasng doses of zinc application on the nutritionand yield of paddy (Oryzasativa L.) plantedby drip irrigation under field conditions

There are many obstacles in front of agricultural activities in today's conditions. One of them is the serious damage to the yield of agricultural products per unit area as a result of recent climate change. In order to combat this situation in rice (Oryza sativa L.) cultivation which has high added value in our country, the effect of one of the micro plant nutrients zinc (Zn) that the plant is sensitive to, on the nutrition of the plant and the increase in yield in the plant as a result of the application of the plant nutrient with increasing doses of fertilizers has been researched. In addition, it is planned to produce at maximum the yield of paddy grown in check flooding conditions using the drip irrigation method under minimum water use conditions.Trial plots applied with 1 plant x 4 replications x 5 different doses (0-20-40-60-80 mg/kg ZnSO4 7.H2O) by using paddy (Oryza sativa L.) plant under field conditions in the agricultural areas of Çatalca District of Istanbul Province. It was carried out according to the "Randomized Blocks Design".As a result of the study, the highest applied zinc content was determined as 301,15 mg/kg in the plants in the paddy parcels given 60 mg/kg zinc dose. This result, which is statistically significant at the 5% level, has been revealed as the most effective value in terms of plant nutrition and interaction with other elements. The importance of zinc fertilization in terms of quality and plant nutrients of rice plant in climate change and limited water usage conditions has been revealed with this thesis.With this research, the zinc deficiency in our country's soils reached serious levels, and paddy, which is a strategic plant, and water resources were contributed to the solution of these problems.
