Response of linseed to organic and inorganic sources of nitrogen

The results of experiments indicated that the treatment T₁₆ (FYM 7.5 t + 37.5 kg N/ha) was found better with respectr to plant height at 45 days and at the time of harvest, number of tillers and capsules/plant, dry matter production, straw and grain yield of linseed. The maximum uptake of N (grain and straw), P and K by linseed straw were recorded with treatment T₁₆ (FYM 7.5 t + 37.5 kg N/ha) in 1992–93 and 1993–94. Whereas, uptake of sulphur by linseed was highest with treatment T₁₆ (FYM 7.5 t + 37.5 kg Nlha) in 1992–93 and 1993–94. The uptake of P and K was similar in linseed grain with the treatments T₁₃ (FYM 6 t + 30 kg Nlha) and T₁₆ (FYM 1.5 t + 31.5 kg N/ha) in 1992–93 and maximum uptake of P and K by linseed grain in 1993–94 with treatment T₁₃. The physico-chemical properties of soil were improved with treatment T₁₆ (FYM 1.5 t + 37.5 kg N/ha).
