Linseed (Linum usitatissimum L.) is one of the oldest rabi oilseed crop under cultivation.
Linseed is cool weather loving crop grown either as sole crop or mixed crop. The productivity of
linseed in Maharashtra is low due to cultivation under residual soil moisture, no input condition,
utera system of cropping and major linseed growing areas are under moisture stress situation and
protected irrigation facilities not available. To meet the requirement of growing population, it is
necessary to increase the productivity of the crop and nutrient management is one of the answers
to this issue. (Chaudhary2009). The main reason for low productivity of linseed is its cultivation
in marginal and sub marginal lands under poor management and input starved rainfed conditions.
Further lack of balanced nutrient management is one of the major causes of low yield.
Methodology
The experiment was conducted at Agricultural Research Farm, Department of Agronomy,
College of Agriculture Parbhani, Maharashtra duringRabi season of 2020. The soil of the
experimental plot was clayey in texture and slightly alkaline in reaction having low in organi
ccarbon, available nitrogen and phosphorus, but marginally high in available potassium.
Experiment was conducted in Split plot design with three replications. The treatments were
consisting of four spacing as main plot treatments and three sulphur levels as sub plot treatments.
The treatments are T1–30×15cm 2 , T2–30 ×10cm 2 , T3–45 ×10cm 2 , T4–45 ×15cm 2 , S1–0,S2–
10Kgha -1 S3–20Kgha -1 .
Results
Results revealed that the mean growth attributes of linseed was significantlyobserved under the
treatment T2 (30cm x10cm) while minimum growth characters was
recordedundertreatmentT4(45cmx15cm). In case of Sulphur levels maximum observations
pertaining to growth was recorded in treatmentS3 where 20 kg sulphur per ha was applied. It was
significantly superior over restof the treatments.
