Abstract:
A field experiment was conducted to evaluate the impact of hydrogel on productivity of linseed variety Kartika under rainfed conditions during Rabi 2016-17 under AICRP on Linseed, RRTTS, Keonjhar, Odisha. The experiment was laid out in Randomised Complete Block Design (RCBD) in factorial treatment design with three hydrogel treatments in the main plot viz. H₁-100% hydrogel (2.5 kgha^-1), H₂-75% hydrogel (1.88 kgha^-1), H₃-50% hydrogel (1.25 kgha^-1) and four carriers viz. Sand, FYM, Vermi-compost and Gypsum in the sub plot. Carriers were applied @ 25 kg/ ha. Results revealed that application of hydrogel (100%) @2.5 kg ha^-1 with vermi-compost recorded the highest plant population (202 plants/m²), higher plant height (59.4 cm) and average no of capsules per plant (24.4) over other treatments. The data reveals that the highest seed yield (989 kgha^-1) was found with application of hydrogel (100%) @2.5 kg/ha with FYM followed by 100% of hydrogel with vermi compost (909.7 kgha^-1) and 50% of hydrogel with FYM (878.0 kgha^-1). The highest B:C ratio 1.77 was recorded with hydrogel (100%) @2.5 kgha^-1 with FYM. Therefore application of hydrogel (100%) @2.5 kgha^-1 with FYM is recommended to linseed for higher productivity and profitability.
