Abstract

This study was conducted to find out the effect of different concentrations (control 5, 10, 25, 50, 100 and 200 mg/l) of chromium on growth, yield of black gram (Vigna mungo L.). Pot culture experiments were carried out with black gram seeds with different concentrations of chromium solution. The morphological growth parameters were recorded at 15, 30, 45 and 60 days old chromium treated plants. The yield was recorded at the time of harvest. The study revealed that, the increase in chromium reduce the growth and and yield in black gram plants.

Highlights

Rapid industrialization has contributed all kinds of pollution in the environment including water pollution due to discharge of untreated industrial effluent containing heavy metals [1]
The plant samples were collected at 15, 30, 45 and 60 d after sowing and they were used for recording the various morphological growth parameters viz., plant height, total leaf area [10] and plant dry weight
The effect of different concentrations of chromium on plant height, total leaf area and plant dry weight of blackgram were recorded at 15, 30, 45 and 60 d after sowing. In this pot culture experiment, the maximum growth of black gram plants was observed at control plants and the minimum growth was observed at 200 mg/l chromium concentrations

Summary

INTRODUCTION

Rapid industrialization has contributed all kinds of pollution in the environment including water pollution due to discharge of untreated industrial effluent containing heavy metals [1]. These heavy metal contaminated polluted water is being used for the irrigation in some dry areas. Chromium plays a major role in polluting the environment. In addition to leather tannery, there are many industries which contribute heavy metal pollution [5]. The research work of chromium on growth and yield response of crops is very meagre. An attempt has been made to examine the impact of various concentrations of chromium on growth, and yield parameters of blackgram (Vigna mungo L.) through pot culture experiments
