Abstract

A field experiment was conducted at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) during Rabi 2015-16. The soil of the experimental field was clay in texture (Vertisols), neutral in pH (6.68), normal in EC (0.18 m mhos m-1 at 25oC), medium in organic carbon (0.50%) and had low in available nitrogen (226 kg ha-1), medium in phosphorus (12.64 kg ha-1), and high in available potassium (367 kg ha-1) contents. The linseed var. ‘RLC-92’sown on 22nd Nov, 2015 using experimental techniques of factorial randomized block design with three replications and eighteen treatments. The treatment consisted of two seed rate viz. 25 kg ha-1 (S1), 30 kg ha-1 (S2), three nutrient management viz. RDF 60:30:30 N, P2O5 & K2O Kg ha-1 (N1), RDF + Incorporation of FYM @ 5 t ha-1 (N2), RDF + FYM placement in rows @ 5 t ha-1 (N3) and three foliar of water spray at 15, 40, 65 and 90 DAS (F1), foliar spray of Nitrobenzene @ 0.06% at 15, 40, 65 and 90 DAS (F2) and foliar spray of 2% urea at 15, 40, 65 and 90 DAS (F3). Recommended agronomic practices were followed for raising linseed. The crop was harvested on 12th March, 2016 for seed yield purpose.

Recommended agronomic practices were followed for raising linseed. The crop was harvested on 12th March, 2016 for seed yield purpose.

The application of RDF + FYM placement in rows @ 5 t ha-1 (N3) recorded higher growth parameter viz. plant height 78.92 cm, 87.06 cm, and 88.44 cm at 60, 90 DAS and at harvest, respectively, yield attributes viz. seed yield (2100 kg ha-1), stover yield (4885 kg ha-1) and energy input, net gain energy and energy output - input ratio (1039.34).The uptake of N, P and K were also observed significantly higher in the same treatment viz. 52.55, 18.36 and 77.24 kg ha-1 respectively. In case of foliar spray, application of 2% urea at 15, 40, 65 and 90 DAS (F3) gave higher growth parameter viz. plant height 78.92 cm, 86.89 cm and 88.37 cm at 60, 90DAS and at harvest, respectively, yield attributes viz. seed yield (2089 kg ha-1), stover yield (4772 kg ha-1) andseed production efficiency (246.99). However, it was statistically at par with the application of foliar spray of 0.06% Nitrobenzene at 15, 40, 65 and 90 DAS (F2). The uptake of N, P and K were also observed significantly higher in the same treatment viz. 50.99, 18.13 and 75.57 kg ha-1 respectively. Interaction among seed rate 30 kg ha-1 (S2) X RDF 60:30:30 N:P:K kg ha-1(N1) with foliar application of 2% urea at 15, 40, 65 and 90 DAS (F3)(S2 XN1X F3)recorded the higher value of seed production efficiency.
