Abstract
A field experiment was conducted during Rabi 2015-16 at Holta Organic Farm of Department of
Organic Agriculture, CSK HPKV, Palampur to study the response of gram to organic and
inorganic sources of nutrients under rainfed and irrigated conditions. The experiment consisted of
8 treatments comprising of combinations of four nutrient management practices i.e. organic
nutrient management [soil treatment with jeevamrit & seed treatment with Rhizobium + PSB,
vermicompost (VC) @ 5 t ha-1 & 3 sprays of vermiwash], inorganic nutrient management
(recommended NPK), integrated nutrient management (2.5 t ha-1 VC + 50% of recommended
NPK) and farmer’s practice (1.25 t ha-1
VC + 25% of recommended NPK) with two conditions
i.e. irrigated and rainfed were tested in split plot design with three replications. Results revealed
that growth, yield attributes, grain and straw yield of gram were increased with irrigated
condition and nutrient management practices. Under irrigated condition, 15.20 per cent higher
yield and 10.41 per cent higher net returns per rupee invested were recorded over rainfed
condition. Among nutrient management practices, organic nutrient management recorded
significantly higher seed yield (1060.1 kg ha -1
) as compared to other treatments, followed by
integrated nutrient management practice. At the same time organic nutrient management recorded
highest net returns (₹ 52467 ha-1
) and 7.10 net returns per rupee invested. Integrated nutrient
management was the second best treatments, recorded higher net returns (₹ 32210 ha-1
) as
compared to inorganic and farmers practice. The available nutrient status of soil (NPK) was
significantly higher under organic nutrient management as compared to other treatments.
