Optimizing wheat yield through seed rate and planting method interactions: A study for enhanced crop productivity and food security

Abstract

Wheat (Triticum aestivum) is a vital cereal crop, contributing significantly to the global food supply. This study conducted between 2020-2021 and 2021-2022, aims to assess impact of different planting methods and seed rates on wheat productivity. Its goal is to optimize wheat yield sustainably by examining various factors affecting wheat production and related traits. It employs the Randomized Complete Block Design (RCBD) with a double-factor split-plot arrangement. The study included three replications and evaluated three seeding methods: P₁ (broadcast method), P² (bed method), and P₃ (drill method). Additionally, five seeding rates were considered: S₁ (25 kg ha^-1), S₂ (50 kg ha^-1), S₃ (75 kg ha^-1), S₄ (100 kg ha^-1) and S₅ (125 kg ha^-1). The study indicates that seeding rates and planting methods significantly impact wheat yield parameters during both years. So, the drill method exhibited uttermost performance by using the seed rate 75 kg ha^-1 (3560 and 3430 kg ha^-1). The maximum yield was achieved at 3231.1, 3122.2 kg ha^-1 during 2020-2022 using a seed rate of 75 kg ha^-1 and drill planting method depicting 3135, 3033.3 kg ha^-1. It can be concluded that the integration of the P₃ (drill method) with S₃ (75 kg ha^-1) has potential to enhance wheat productivity by improving crop stand and resource acquisition. Thus, there is potential to benefit both the farming and scientific communities by enhancing food security, advancing agricultural knowledge, and supporting sustainable wheat production practices.
