Influence of municipal solid waste compost [MSWC] on the growth and yield of green gram Vigna radiate [L wilczek], fenugreek [Ttrigonella foenum-graecum L.] and on soil quality

ABSTRACT

Pot culture experiments were carried out to study the effect of characterized municipal solid waste compost [MSWC] amendments [0, 50,100,250, 500, 750 and 1000 g] with garden soil [6 kg] on the growth and the yield of green gram [Vigna radiata [L] wilczek] and fenugreek [Trigonellafoenum-graecum L.] as well as changes on soil quality. The growth and the yield of green gram and fenugreek were enhanced by MSWC application upto 500 g. Soil amended with > 500 g MSWC inhibited the plants biometric parameters neither with-significantly nor without-significantly suggest a possible toxic effects to both plants. No dosage effect was detected for total chlorophyll synthesized, except green gram grown in 1000 g of MSWC amendments. Compared with control, percentage of protein was increased significantly upto 250 g for green gram and 500 g for fenugreek. A significant reduction in percentage of carbohydrates was observed above 750 g of MSWC exposure for green gram and above 500 g for fenugreek. There was no specific trend and significant changes were observed in percentage of reducing sugars in both plants except green gram exposed to 50 g MSWC exposure. There was no significant difference in all plant yield parameters of both plants except fenugreek seed weight in 250 g MSWC amendment. Generally, chemical parameters of soil are improved by the addition of MSWC, after 90 d of experimental period
