Abstract

The experiment was conducted at the Punjab Agricultural University, Ludhiana during 2013 and 2014 on sandy loam soil to study the effect of integrated nutrient management (INM) on microclimatic variations, yield and yield attributes of baby corn (Zea mays L.). Results showed that the microclimatic parameters as well as yield and yield attributes of baby corn were significantly influenced by the treatments. At 60 days after sowing the maximum photosynthetically active radiation interception (93.2 %) and lowest soil and canopy temperature (29.8 and 32.0 0C) was recorded by the application of N-P-K 75-15-11.3 kgha-1. The corn yield and yield attributes, LAI and chlorophyll content were also significantly higher in this treatment.

Highlights

Maize, the third most important cereal crop in the world following wheat and rice, has been cultivated for centuries as a grain crop and more recently as a vegetable crop, such as baby corn and sweet maize (Zea mays var. saccharata)
The amount of absorbed photosynthetic photon flux density (PPFD) depends on the efficiency of radiation interception by the canopy, which in turn depends on plant morphology and physiology
This efficiency depends on the leaf area index (LAI) and on the extinction coefficient, which is related to the canopy structure, especially concerning the shape of the leaf and its inclination (Lindquist et al, 2005)

Summary

Introduction

The third most important cereal crop in the world following wheat and rice, has been cultivated for centuries as a grain crop and more recently as a vegetable crop, such as baby corn and sweet maize (Zea mays var. saccharata). Keywords : Baby corn; PAR interception; INM and LAI. The objective of this analysis was to examine the effects of INM on variation in intrercepted PAR and temperature on potential baby corn (Zea mays L.) yield.
