Abstract
A field experiment was carried out on crops sesame and black gram
during Kharif 2020, and the same field INM study was carried out in Rabi season 2020-21 on
chickpea and mustard crops. The experiments were conducted on heavy clay soil at
Agriculture Research Farm, College of Agriculture, Banda University of Agriculture &
Technology, Banda. The experimental design was split-plot with main factor two cropping
systems viz. Sesame – Chickpea and Blackgram-Mustard and sub-factor eight integrated
nutrient management viz. farmer fertilizer practice (T1), 100 % RDF (T2), 100% RDF + FYM
(T3), 100 % RDF + FYM + Zn(10 kg ha-1
) (T4), 125 % RDF + FYM+ biofertilizer consortia
(BC) (Rhizobium spp., PSB and Azotobacter spp.) (T5), 100 % RDF + FYM+BC (T6), 75%
RDF + FYM+BC (T7) and 50 % RDF +FYM+BC (T8), all treatments were replicated thrice.
The FYM was applied @ 5 t ha-1
. The physicochemical properties of experimental soil were as
follows; neutral pH (7.58), electrical conductivity (0.16 dSm-1
), low in organic carbon (3.80 g
kg-1
) and medium in available phosphorus (16.4 kg ha-1
) and available potassium (250.5 kg ha1
). The experimental results revealed that application of 125% and 100 % RDF along with
FYM and biofertilizer consortia increased significantly nodule number, nodule weight per
plant and number of pods per plant, thereby increased grain yield of chickpea significantly in
comparison to farmers fertilizer practice (T1), sole application of 100 % RDF (T2) and 50 %
reduction of RDF along with FYM and biofertilizer consortia (T8). The similar results were
obtained with the mustard crop. The growth, yield attributes, and yield were significantly
improved by applying 125% and 100 % RDF along with FYM and biofertilizer consortia (T5
and T6) treatments. The maximum B:C ratio was obtained with T6 treatment (3.05) and
minimum in T8 i.e., 2.52, irrespective of the cropping systems. A slight improvement in
organic carbon and available phosphorus was observed from the initial value. The watersoluble carbon (WSC) was higher in treatments T5 and T6 than sole fertilizer application in T1
and T2, irrespective of the cropping systems. Sesame-Chickpea cropping system also had
higher WSC than a black gram –mustard system. The available phosphorus was also higher in
T5 and T6 treatments than T1-T4 and T8 treatments. Overall, the study recommends addition of
100 % RDF along with FYM (5 t ha-1
) and biofertilizer consortia to chickpea and mustard
crops during the initial year of cultivation in low organic carbon and available phosphorus
soils for the better productivity, profitability and sustain of soil fertility. As 75 % RDF with
FYM and biofertilizer also performed good and slight changes in soil fertility observed. Longterm studies on INM in various cropping systems are, thus, required in order to monitor
changes in soil properties and reduce fertilizer dose across a wide range of ecologies.
