Abstract
The investigation was undertaken during 2017-18 to study the effect of conjoint use of organic and inorganic sources of nutrient on soil properties, yield and uptake of nutreints in french bean and wheat under poplar based agroforestry system at at old site of Agroforestry Research Centre, Patharchatta of G.B.

The experiment comprised of nine different treatments having different combinations of organic and inorganic nutrient sources which were replicated 3 times in randomized block design. The experimental soil was an Aquic Hapludoll with sandy loam texture. The soil sample were collected from surface and subsurface soil and results revealed the highest amount of organic carbon (1.52%), SOC stock (31.34 Mg ha-1),
available N (340.77 kg ha-1), available P (24.93 kg ha-1), available K (239.68 kg ha-1) , DHA (384.52 μg TPF g-1 soil 24 h-1), phosphatase activity (292.59 μg PNP g-1 soil h-1) and SMBC (381.81 μg g-1 soil) was observed in treatment T7 (50% N through VC + FYM + 50% through RDF + inoculum) after harvesting of french bean. While after harvesting of the wheat crop, the highest amount of organic carbon (1.50%), SOC stock
(28.94 Mg ha-1), available N (338.68 kg ha-1), available P (24.61 kg ha-1), available K (238.56 kg ha-1) , DHA (347.10 μg TPF g-1 soil 24 h-1), phosphatase activity (260.89 μg PNP g-1 soil h-1) and SMBC (365.42 μg g-1 soil) was observed in treatment T8 (100% NPK + FYM+ VC).
The highest plant height (55.63cm), number of pods per plant (37.66), pod length (13.60 cm) and number of grains per pod (6.66) in french bean were observed in the T7 (50% N through VC + FYM + 50% through RDF + inoculum). While in wheat crop the highest plant height (96.77 cm), spike length (10.31 cm) and number of grain per ear (50.00) were recorded with the T8 (100% NPK + VC + FYM). The highest grain yield (25.5 q/ha), straw yield (29.53 q/ha) and biological yield (55.03 q/ha) of french bean were observed in treatment T7. On the other hand the
highest grain yield (37.14 q/ha), straw yield (65.17 q/ha) and biological yield (102.31 q/ha) of wheat were recorded with the T8 (100% NPK + VC + FYM). Therefore, from this experiment it is concluded that the conjoint use of organic and inorganic sources of nutrient i.e. T7 and T8 in french bean and wheat crop, respectively significantly improved the soil physiochemical, biological properties, crop growth, yield and nutrient uptake.
