The Effects of Different Irrigation Applications and Different Planting Methods on the Yield and Growth Parameters of Paddy

Abstract

Paddy is one of the most important cereal crops, which is a basic food source for more than half of the world's population. In order to feed the increasing world population sustainably, the need to intensify studies on the development of agricultural irrigation methods and efficient use of water resources is increasing. It is estimated that rice uses 34-43% of irrigated agricultural land. Water resources are rapidly decreasing on a global scale and the total amount of irrigation water needed for paddy production varies according to various factors such as the type of paddy used, soil properties and planting methods. The study was designed as a 'Randomized plots' experimental design. In the study, 2 varieties, 2 different irrigation methods (Conventional, AWD) and 3 different planting methods (Irrigated, Dry and Seedling) were carried out in 36 lysimeters as three replications. In the study, characteristics related to rice such as plant height, main stem thickness, cluster length, number of plants per square meter, grain yield, thousand grain weight, yield with and without breakage were examined. It was determined that the research topics had a statistical effect on the parameters examined. In terms of grain yield, it was determined that grain yield decreased by 25% between traditional irrigation and AWD irrigation in water application. In terms of planting methods, Irrigated planting, dry sowing and seedling methods followed each other. As a result of the research, it was determined that the highest grain yield was obtained in the water planting method and with traditional irrigation.
