Abstract
A field experiment entitled “Integrated nutrient management in blackgram
(Phaseolus mungo L.)” was conducted on clay loam soil having medium fertility
(268.40, 19.50 and 370.80 kg, available N, P2O5 and K2O ha-1, respectively), EC 1.13
dSm-1 and pH 7.8 at Agronomy Farm, Rajasthan College of Agriculture, Udaipur
during 2003-04 and 2004-05. The experiment consisted of 32 treatment combinations
comprising of two levels of farm yard manure (0 and 5 t ha-1), four levels of
phosphorus (0, 50, 75 and 100 % on the basis of STR) and four levels of biofertilizers
(No inoculation, PSB, VAM and PSB + VAM). Experiment was conducted under
split plot design having FYM and phosphorus in main plots and biofertilizers in sub
plots with three replications and blackgram as a test crop. The residual effect of
treatments were evaluated with wheat crop in sequence.
Treatments were evaluated in terms of seed/grain, stover/straw and biological
yields and uptake of nutrients (macro and micro) by blackgram and succeeding wheat.
Post harvest soil properties were also determined after each crop to assess the change
in physico-chemical properties and fertility status due to cropping and treatments
under investigation.
The results of the study showed that application of FYM @ 5 t ha-1 or
application of 40 kg P2O5 ha-1 (100 % as based on STR) increased significantly the
seed, stover and biological yield of blackgram as well as of succeeding wheat grown
in sequence on residual FYM + P. Biofertilizers viz., PSB, VAM and PSB + VAM
(dual inoculation) inoculation to blackgram significantly increased the seed, stover
and biological yields of blackgram and yields of succeeding wheat grown in
sequence.
