Influence of SSNM and STCR approach on growth and yield attributes of maize (Zea mays L.)

Abstract

The field experiment was conducted during kharif 2024 at Post Graduate Research Farm, Agronomy Section, College of Agriculture, Dhule to study growth and yield attributes of maize (Zea mays L.).” on variety Phule Champion as influenced by nutrient management through SSNM and STCR fertilization approaches. The experiment was laid out in randomized block design with three replications. The treatments comprised of eight nutrient management viz., T1- Absolute control, T2 - GRDF (120: 60: 40 N: P2O5: K2O kg ha-1 + FYM 10 t ha-1), T3- SSNM Yield target 8 t ha-1, T4- SSNM Yield target 10 t ha-1, T5 - SSNM Yield target 12 t ha-1, T6 - STCR Yield target 8 t ha-1, T7 - STCR Yield target 10 t ha-1 and T8 - STCR Yield target 12 t ha-1. Among the treatments, SSNM through fertilizers for targeted yield of 12 t ha-1 (T5) recorded higher plant height, number of functional leaves plant-1, leaf area plant-1 (dm2), dry matter plant-1, cob length with husk, cob girth with husk, weight of cob with husk, number of grain rows cob-1, number of grains row-1 and grain weight cob-1 as compared to other treatments.
