Abstract

Experiments were simultaneously conducted at the Tamil Nadu Agricultural University, Coimbatore with fifteen soybean genotypes in three environments to study the lodging pattern and to identify the lodging resistance or susceptability of soybean genotypes for appropriate use in various cropping systems. Soybean plants lodged severely within two coconut stands due to shade effect. The mean lodging per cent was 83.9 and 95.3 under eight and eighteen year old coconut plantations, respectively. The variety Hardee and Monetta recorded very low (less than 10 per cent) lodging percentages under eight year old coconut plantation. Besides these UGM 21 recorded low lodging per cent under eighteen year old coconut plantation which showed their shade tolerance
