Title: “Evaluation of establishment method and nano nitrogen on seed yield and quality of finger millet (Eleusine coracana (L.) Gaertn.)”
The present investigation was conducted during kharif season of 2021 at Research and Extension Centre, Gaja, Collage of Forestry, Ranichauri, Tehri Garhwal of VCSG Uttarakhand University of Horticulture & Forestry, Bharsar, Pauri Garhwal, Uttarakhand, at 30̊ 16’17” N latitude and 78̊ 25’21” E longitudes to investigate the establishment method and nano nitrogen on seed yield and quality of finger millet (Eleusine coracana (L.) Gaertn.). The experiment was laid out in randomized block design with three replications under field conditions. The treatments comprises fourteen treatments viz., T1- TP + RDF, T2- DS + RDF, T3- TP + PK, T4- DS + PK, T5- TP+ 50%N+ ST, T6 - TP+ 50%N+ RD, T7 - TP+ 50%N+ FS, T8 - TP+ 75%N+ ST, T9 - TP+ 75%N+ RD, T10- TP+ 75%N+ FS, T11 - DS+ 50%N+ ST, T12 - DS+ 50%N+ FS, T13 - DS+ 75%N+ ST and T14 - DS+ 75%N+ FS. The recommended dose of fertilizer was used NPK 40:20:20 kg/ha. In treatment T3 and T4, no nitrogen was applied and NPK was applied at the rate of 0:20:20 kg/ka. While laboratory experiments were conducted in completely randomized design (CRD) with four replication to assess the seed quality of the harvested seeds.
The establishment method and nano nitrogen had significantly influenced the growth parameters, yield attributes parameters, yield and economics of finger millet. The significantly higher growth parameters and seed yield were recorded in DS + RDF followed by TP+ 50% N+ ST, TP+75 %N+FS and DS+50%N+FS. The economics of finger millet was significantly higher in DS + RDF. The higher B:C ratio was recorded in DS + RDF followed by DS+50% N+ ST and DS+50%N+FS.
The seed quality attributes, under standard germination test viz., germination parentage, seedling total length, seedling fresh and dry weight, seedling vigour indices, radicle emergence and speed of germination were recorded higher in DS+RDF followed by DS+50%N+FS and TP+75 %N+FS. Under stress tests viz., accelerated aging, cold test and water sensitivity test, the significantly higher value of seed quality parameters were recorded in DS+RDF and DS+50%N+FS.
On the basis of investigation, it could be concluded that drill sowing of finger millet with recommended dose of fertilizer (NPK 40:20:20 kg/ha) was useful to get higher return from the finger millet crop. To reduce the use of chemical fertilizer without compromising seed yield and seed quality of finger millet significantly, DS+ 50%N+FS and TP +75%N+FS can be used.
