Abstract
A field experiment entitled “Effect of Vermiwash From Different Organic
Resources on Growth, Yield and Quality of Organic Blackgram [Vigna mungo (L.)
Hepper]” was conducted at Organic farming unit, Rajasthan College of Agriculture,
MPUAT, Udaipur during kharif, 2018. The soil of the experimental site was clay loam
in texture with 241.2, 20.9 and 351.3 kg ha-1 available nitrogen, phosphorus and
potassium, respectively in 0-30 cm soil depth with pH 8.1 and 0.55 per cent organic
carbon. The experiment consisted of nine treatments [vermiwash from 100% cow
dung, vermiwash from 100% buffalo dung, vermiwash from 50% cow dung + 25% dry
farm waste + 25% green farm waste, vermiwash from 50% buffalo dung + 25% dry
farm waste + 25% green farm waste, vermiwash from 90% green waste incubated with
10% cowdung, vermiwash from 90% green waste incubated with 10% buffalo dung,
vermiwash from 90% dry waste incubated with 10% cow dung, vermiwash from 90%
dry waste incubated with 10% buffalo dung and water spray (control)]. The nine
treatments were replicated thrice in Randomize Block Design. Blackgram variety PU-
31 was used as test crop.
A significant increase in plant height and dry matter at 45, 60 DAS and at
harvest, root length at 45 and 60 DAS, number of effective root nodules at 50%
flowering, chlorophyll a, chlorophyll b and total chlorophyll at 45 DAS, number of
pods plant-1 and number of seeds pod-1, test weight, seed yield, haulm yield and
biological yield, nitrogen, phosphorus, potassium, zinc and iron content in seed and
haulm and their uptake and protein content in seed were observed with the application
of vermiwash from 100% cow dung over control and other treatments. Vermiwash
from 100% cow dung have minimum pH and electric conductivity and contain
maximum organic carbon, nitrogen, phosphorus, potassium, calcium and magnesium
followed by vermiwash from 50% cow dung + 25% dry farm waste + 25% green farm

waste under 35 days after collection of vermiwash over other vermiwash treatments.
Significantly the highest seed yield (800 kg ha-1) and net returns ( 62,592 ha-1) of
blackgram was obtained with the application of vermiwash from 100% cow dung.
Application of vermiwash from different organic resources had no significant effect
on plant population, harvest index and soil pH, electrical conductivity (EC), organic
carbon content, available nitrogen, phosphorus, potassium, zinc and iron content of
soil after harvest of blackgram.
