Abstract
An experiment was conducted at University Research Farm, Banda University of
Agriculture and Technology, Banda (U.P.) on the topic entitled “Response of greengram
[Vigna radiata (L.)] varieties to various NPK doses under Bundelkhand Agro-climatic
conditions” during kharif 2022. The main aim of this experiment is to find out the best
performing greengram variety, most suitable dose of fertilizer and interaction among them.
The experiment comprises of two factor treatments conducted in Split plot design with three
main plot factors and three sub-plot factors. The total combination of treatments was nine
and each treatment replicated thrice. The main plot consists of three greengram varieties,
IPM 02-3, IPM 410-3 and PDM-139. Further, each main plot is divided into three sub-plots
consists of three different recommended doses of fertilizers viz., 75%, 100% and 125% RDF
where, 100% RDF consist of 25:50:30 NPK kg ha-1
. The soil in which experiment conducted
was silty clay, pH value is (7.85), E.C. (0.28 dSm-1
), Organic carbon (0.41%), available N2
(192 kg ha-1
), P2O5 (9.42 kg ha-1
), K2O (208.04 kg ha-1
).
Observations on growth parameters, quantitative and qualitative attributes of
greengram were recorded as and when required. The following conducted study reveals that
the greengram variety IPM 02-3 performs better in comparison to other varieties i.e., IPM
410-3 and PDM-139. Among doses, 125% RDF of NPK had recorded better performance
regarding growth attributes viz., Plant height (cm), plant dry matter (g plant-1
), number of
branches (plant-1
) and LAI and yield attributing parameters viz., Number of pods (plant-1
),
length of pods (cm), test weight (g), straw yield (q ha-1
) and biological yield (q ha-1
). The
interaction of variety IPM 02-3 with 125% RDF of NPK in growth viz., LAI and rhizobium
root nodule count (plant-1
) and yield viz., Number of pods (plant-1
), biological yield (q ha-1
)
is found to be best in comparison to 75% and 100% RDF. Economically, 100%
recommended dose of fertilizer of NPK was significantly higher in gross return, net return
and B:C ratio. Based on the experimental observations, it was concluded that farmers under
Bundelkhand Agro-climatic conditions can cultivate greengram variety “IPM 02-3” with
100% recommended dose of fertilizer for achieving maximum growth, yield and economical
benefits.
