Influence of planting geometry and nitrogen level on rice Shashank Shekhar Singh

A field experiment was conducted on the topic entitled "Influence of planting geometry and nitrogen level on rice (Oryza sativa L.)" during two consecutive kharif seasons of 2017 and 2018 at Agronomy Research Farm, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (U. P.) Experiment was comprised with sixteen treatment combinations viz. four planting geometry and four nitrogen levels in split plot design. Four planting geometry i.e. 15x10 cm, 15x15 cm, 20x10 cm and 20x15 cm were kept in main plots and four nitrogen levels i.e. 0 kg N/ha, 60 kg/N ha, 120 kg N/ha and 180 kg/N ha were kept in sub plots. The experiment was replicated three times. As per requirement of seedlings, seeds NDR-359 variety of rice was used as per treatment of planting geometry Crop was uniformly fertilized with 60 kg P2O5, 40 kg K2O and nitrogen as per treatments. Results reveal that planting geometry of 20×10cm was found suitable for higher yield attributes and yield of rice. Application of 120 kg nitrogen/ha was found suitable for higher production of rice.
