Effect of Different Cultivation Systems on the Growth and Yield of Three Varieties of Rice (Oryza sativa L.)

Abstract

A field experiment was carried out at Al-Najaf Governorate at Rice Research Station - Mishkaab / Agricultural Research Office during the summer season of 2019 to study the effect of cultivation methods for three varieties of rice, using Randomized Complete Block Design (RCBD) in a split plot arrangement with three replicates. The study contains three varieties of Rice (Anmbar33, Yasmine and Furat1) as main treatments, whereas, sub plots contain four treatments of the cultivation methods (direct seeds drilling in plots (flat sowing) its symbol (S1), transplanting seedlings in plots (flat sowing) its symbol (S2), direct seed drilling by mastaba method (raised bed sowing) its symbol (S3) and transplanting seedling by mastaba method (raised bed sowing) its symbol (S4)). The results presented the superiority of the variety Furat1 significantly gave the best results of (weight of 1000 grains (gm), number of panicles.m2, and yield ton. ha-1. The treatment of cultivation method S4 was also superior by giving the best results of (Panicle Length cm, Number of Days from Planting to 100% Flowering, Number of Grains. panicle -1, and Yield ton. ha-1).
