Abstract
A field experiment was conducted during kharif season of 2018 at
Instructional Farm (Agronomy), Rajasthan College of Agriculture, Udaipur
(Rajasthan) to study the “Effect of Enriched Compost and Zinc on Soil Fertility
and Productivity of Blackgram (Vigna mungo L.) in Typic Haplustepts”. The
experiment was laid out according to Randomized Block Design with three
replications. The treatments consisting of four levels of enriched compost (0, 2, 4 and
6 t ha-1) and four levels of zinc (0, 2, 4 and 6 kg ha-1) were applied to the blackgram
var. PU-31 as soil application with uniform application of nitrogen and phosphorus as
per recommended doses. The main findings of investigation are summarized as:
1. The increasing levels of enriched compost application increased the number of
nodules per plant, number of pods per plant, number of seeds per pod, test
weight, seed and straw yield as well as content and uptake of nitrogen,
phosphorus, potassium and zinc in seed and straw, protein content in seed and
net returns as compared to control. The pH and electrical conductivity of soil
decreased whereas, organic carbon and available nitrogen (N), phosphorus
(P2O5), potassium (K2O) and zinc (Zn) content of soil at harvest stage of crop
was increased significantly with increasing levels of enriched compost.
2. The application of zinc increased significantly the number of nodules per plant,
number of pods per plant, number of seeds per pod, test weight, seed and straw
yield, content and uptake of nitrogen, phosphorus, potassium and zinc in seed
and straw, protein content in seed and net returns as compared to control. The
application of zinc significantly enhanced the available nitrogen (N), potassium
(K2O) and zinc (Zn) content in soil and available phosphorus (P2O5) in soil
decreased whereas, the pH, electrical conductivity and organic carbon were
found to be non-significant at harvest stage of crop.
3. The significantly maximum seed yield and net returns ware observed under the
treatment EC3 (Enriched compost @ 6 t ha-1) and Zn3 (Zinc @ 6 kg ha-1),
respectively. However, the increase was significant upto EC2 (Enriched compost
@ 4 t ha-1) and Zn2 (Zinc @ 4 kg ha-1) which was also found to be statistically at
par with EC3 and Zn3, respectively. Therefore, in this tract for blackgram variety
PU-31, the application of enriched compost @ 4 t ha-1 and zinc @ 4 kg ha-1 as a
most profitable dose is being recommended for higher seed yield and net returns
per hectare in sub-humid Southern hills and Aravali region of Rajasthan.
