Abstract
French bean (Phaseolus vulgaris L.) is one of the precious and highly relished
vegetables of family Leguminoseae (Fabaceae). As per worldwide consensus, sole
dependence on chemical input based agriculture is not suitable in long run and only
integrated plant nutrient systems (IPNS) involving a combination of fertilizers, organic
manures and bio-fertilizers are essential to sustain crop production, preserve soil health
and biodiversity. Use of organic manure with optimum rate of fertilizer under intensive
farming system increases the turnover of nutrients in the soil plant system.
An experiment entitled “Integrated nutrient management on French bean
(Phaseolus vulgaris L.)” was proposed and conducted during Rabi 2018-19. The
experiment was laid out in Randomized Block Design (RBD) with nine treatments
replicated thrice with a view to study yield and economics of French bean. The
treatments were 50%RDF + 25%FYM + 25% Vermicompost (T1), 75% RDF + 25%
FYM (T2), 75% RDF + 25% Vermicompost (T3), 75%RDF + 25%FYM + Bio-fertilizer
(Rhizobium + PSB) (T4), 75% RDF + 25% Vermicompost + Bio-fertilizer (Rhizobium +
PSB) (T5), 75%RDF + 12.5%FYM + 12.5% Vermicompost + Bio-fertilizer (Rhizobium
+ PSB) (T6), 100%RDF (Chemical fertilizer) (T7), 100%RDF (Organic Matter) (T8) and
Control where no treatment was given (T9). Soil of the experimental site was sandy
loam with pH 6.1, available nitrogen (229.79kg/ha), available phosphorus (35.4kg/ha)
and available potassium (237kg/ha). The variety used was Swarna Priya. The
observations regarding growth were recorded at 30 days interval and yield parameters
were recorded at harvest.
Results revealed that maximum yield of 97.93 q/ha was obtained by applying
75% RDF + 25% Vermicompost + biofertilizer (PSB + Rhizobium), which was
significantly higher than sole application of recommended dose of fertilizers that
produced 71.99 q/ha. Application of 75% RDF + 25%Vermicompost + Bio-fertilizer
(Rhizobium+PSB) also produced maximum B:C ratio of 2.82.
On the basis of one year experiment it may be inferred that for obtaining higher
yield of French bean, application of 75% RDF + 25% Vermicompost + biofertilizer (PSB
+ Rhizobium) is beneficial that yielded 97.93 q/ha of fresh French bean costing Rs.
52,064/- with net benefit of Rs. 94,830/- and B:C ratio of 2.82.
