Influence of Different Age of Seedlings and Micro Nutrient Management Practices on Growth and Yield Attributes of Rice (Oryza sativa L.) under System of Rice Intensification

Abstract

Background: The age of the seedlings at transplanting is a crucial component in achieving uniform rice stands since it influences prospective agronomic features. A micronutrient is the relative amount of a nutrient necessary for plant development. It participates in metabolic activities, enzymatic mechanisms. As a result, all of these, directly and indirectly, contribute to plant growth and development. The growth of rice depends on both the age of seedlings and micronutrients. So, based on the above considerations, we conducted our experiment entitled “Influence of different age of seedlings and micronutrient management practices on growth attributes and yield attributes of rice (Oryza sativa L.) under system of rice intensification.” Methods: An experiment was conducted at experimental research farm Rampur, Selaqui, Doon PG College of Agriculture and Allied Sciences, Dehradun during kharif season of 2016. The experiment was laid out in factorial randomized block design with twelve treatments and was replicated thrice viz., in which factor A consists of different age of seedlings viz., 14 days, 21 days and 28 days and factor B consists application of micronutrients at different days viz., 0.5% ZnSO4, FeSO4 at 20 and 30 DAT. Result: The results of the study revealed that the 14 days age of seedling with the foliar application of 0.5% ZnSO4 + 0.5% FeSO4 at 20 and 30 DAT resulted in maximum plant height, no. of tillers/m2 and highest grain and straw yield.
