Production efficiency (kg/day/ha) and economic efficiency (Rs./day/ha)
The data pertaining to production efficiency (kg ha
-1 day
-1) and economic efficiency (Rs. ha
-1 day
-1) of the cropping system during both the years are presented in Table 2, 3 and 4. The mean production efficiency (kg ha
-1 day
-1) were 43.30, 41.18, 42.29 and economic efficiency (Rs. ha
-1 day
-1) were 1122, 1231, 1177 during first year, second year and on pooled mean basis, respectively.
Crop sequences
The data in Table 1 show that Soybean-onion (CS
1) recorded significantly more economic efficiency and production efficiency than soybean-potato (CS
2) in first year of research. This might be due to higher yield of onion than potato in soybean based cropping sequence. Similar results were reported by
Pacharne (2014) and
Thorat et al., (2018).
Integrated nutrient management levels to soybean (kharif)
Soybean crop supplied with IN
3 (100% RDN applied with FYM@ 5 t per ha and biofertilizer) and IN
2 (75% RDN applied with FYM@ 5 t per ha and biofertilizer) both being at par with each other registered significantly higher production efficiency and economic efficiency than IN
1 (50% RDF applied with FYM@ 5 t per ha+ biofertilizer (Table 2). This might be due to rapid release of nutrients through inorganic sources of nutrient during early phase of growth and development of soybean and gradual release of nutrients during later phase of growth and development of soybean by the organic sources. In addition to that seed of soybean treated with biofertilizer which help to fix atmospheric nitrogen and solublize insoluble phosphorus in soil. Similar results were recorded by
Thimmegowda (2006) and
Thorat et al., (2018).
Recommended dose of fertilizer levels to onion and potato (rabi)
The application of 125 % RDF (F
3) level to
rabi crop recorded significantly higher production efficiency and economic efficiency than lower levels of recommended dose of fertilizer (Table 2). This might be due to residual effect of integrated nutrient management levels applied to
kharif crop enhanced the nutrient uptake and yield potential of
rabi crops. These results were similar findings of
Gaud (2004),
Gudhade (2008),
Senthivelu et al., (2009), Shanwad et al., (2010), Subehia and Sepehya (2012),
Thorat et al., (2018).
Interaction
Production efficiency (kg/day/ha) and Economic efficiency (Rs./day/ ha)
The data presented in Table 3 and 4 indicate that soybean crop supplied with IN
3 and
rabi crops (onion and potato) supplied with F
3 registered highest production economic efficiency over other treatments except combination of IN
2 to soybean and F
2 to
rabi crops(onion and potato).
