| Abstract | ||||
| Two field experiments were conducted at the Experiment and Research Center, Fac. Agric., Moshtohor, Benha Univ., Qalubia Governorate, Egypt, in the summer seasons 2021 and 2022 to study the performance of seven genotypes of rice under three levels of nano-N spraying on growth, yield and its attributes. The most important results obtained from this study can be summarized as follows: The results of the study revealed that the maximum highest No. tillers plant-1 (23.26 tiller), No. spikes plant-1 (19.98 panicle), panicle length (25.41 cm), panicle weight (4.39 g), 1000-grain weight (29.11 g) and grain yield plant-1 (59.48 g) obtained by spraying with 800 ml fed-1 concentration treatment, while, spraying with zero and 400 ml fed-1 concentration treatments were decreased No. days to 50% flowering in the combined analyses. Rice genotypes were highly significant affected on all of the studied characters. G2 genotype was the earliest in No. days to 50% flowering compared with other rice genotypes, whereas, G1 genotype gave the highest values of No. tillers plant-1, No. spikes plant-1, panicle weight, 1000-grain weight and grain yield plant-1, while, G5 genotype gave the highest value of panicle length in the combined analyses. Effect of the interaction between nano-N spraying treatments and rice genotypes were showed highly significant for No. tillers plant-1, No. spikes plant-1, panicle length, panicle weight, 1000-grain weight and grain yield plant-1. Generally, spraying with 800 ml fed-1 concentration treatment under G1 genotype recorded the highest values for these traits except panicle length in combined data. It could be complemented that under the conditions of the experiment, planting G1 genotype with spraying with 800 ml fed-1 concentration is recommended. | ||||
