Optimizing Productivity and Economics of Linseed By Different Organic and Liquid Organic Manures

The declining rate of productivity and environmental sustainability is forcing growers to use
organic manures as a source of nutrient supplements in linseed farming. The present investigation
was conducted during Rabi season of 2021-22, 2022-23 and 2023-24 at AICRP on Linseed and
Mustard, college of Agriculture, Nagpur, Dr. PDKV, Akola to evaluate the productivity and
economics of linseed influenced by different organic manures and liquid organic manures. In
Linseed organic production systems, major challenges like crop-weed competition, nitrogen stress
at critical growth stages due to slow mineralization of organic manures, pest infestation impede to
the optimal yield of linseed. The experiment was laid out in Randomized Block Design (RBD)
consisting of ten treatments and three replications. The results of pooled data of three years
indicated that application of FYM to supply 33% RDN + Neem cake to supply 33% RDN
followed by foliar spray of vermiwash (10%) at branching, flowering and capsule development
stage recorded significantly higher linseed seed yield, gross monetary returns, net monetary
returns and benefit-cost ratio. The combined application of FYM to supply 33% RDN + Neem
cake to supply 33% RDN followed by foliar spray of vermiwash (10%) at branching, flowering
and capsule development stage also registered 7.70% and 16.12% higher seed yield of linseed
than the application of FYM to supply 33% RDN + Neem cake to supply 33% RDN followed by
foliar spray of cow urine (2.5%) at branching, flowering and capsule development stage and
combine application of FYM to supply 33% RDN and Neem cake to supply 33% RDN without
foliar spray of liquid organic manures. The combine application of organic manures and foliar
spray of liquid organic manures was reflected as an economically viable practice as evidenced
from higher yields and monetary benefits.
