    Title: “Optimization of nano-DAP fertilization for improvement in growth, yield and seed quality of finger millet (Eleusine coracana (L.) Gaertn.)” The management of nutrients is crucial for increasing finger millet's yield. The overuse of fertilizers haveresulted in lower fertilizer efficiency due to leaching losses, volatilization and denitrification losses. The availability of phosphorus is lesser due to fixation of phosphorus at soil collides. In order to avoid or minimize such losses and fixation, seed treatment with foliar application of nano-DAP is one of the fastest ways to enhance crop growth. The current investigation was conducted in kharif 2022, with variety VL-352 at Research and Extension Centre, Gaja, College of Forestry, Ranichauri (Tehri Garhwal), Uttarakhand. The experiment comprised of ten treatments viz., T1- NK 100% (Control), T2- NPK 100%, T3- 75%P+ 100%N+ 100%K, T4- 50%P+ 100%N+ 100%K, T5- 75%P+ 100%N+ 100%K+ ST+FS(2ml), T6- 75%P+ 100%N+ 100%K+ ST+FS(4ml), T7- 50%P+ 100%N+ 100%K+ST+FS(2ml), T8- 50%P+100%N+100%K+ST+FS (4ml), T9- 50%P + 100%N + 100%K +ST+FS(2ml)+FS(2ml), T10- 50%P+100%N + 100%K + ST+FS (4ml)+FS(4ml) and was laid out in Randomized Block Design (RBD) with three replications. The seed quality parameters of freshly harvested finger millet seeds were assessed for seed quality parameters in Complete Randomized Design (CRD) with three replications at laboratory of the Department of Seed Science and Technology, College of Forestry, Ranichauri. The significantly higher plant growth parameters, yield attributing parametersand seed yield were recorded in T10- 50%P+100%N + 100%K + ST+FS (4ml)+FS(4ml) which was found to be statistically at par with T2- NPK 100% and significantly lower yield was recorded in T1- NK 100% (Control). The seed quality attributes like germination percentage, seedling length, seedling fresh and dry weight, vigour index, speed of germination, germination percentage under stress tolerance tests were recorded significantly higher in the treatment T10- 50%P+100%N + 100%K + ST+FS (4ml)+FS(4ml). Based on the present investigation it can be concluded that the use of 50% P through DAP and 100% NK along with seed treatment by nano DAP @5ml/kg seed as well as two foliar sprays of nano-DAP @4 ml/l of water, first at 30-35 days after germination and second at 45 days after seed germination gave significantly higher plant growth, seed yield and seed quality of finger millet.

    (College of Forestry, Ranichauri, 2023) Bisht, Aditya Raj; Paliwal, Arunima(Dr.); Kumar, Ajay(Dr.) (Member); Kumar, Pankaj (Dr.) (Member); Rawat, Deepa(Dr.) (Member)
    Title: “Response of promising adzuki bean (Vigna angularis) genotypes to different fertility levels” Azuki bean (Vigna angularis) belongs to a group of legumes known as the Asian Vigna. China is the largest producer of adzuki with an estimated production of about 260 thousand tons in the year 2019-20 and followed by Japan. In India, it is considered as a potential crop and its cultivation is limited to the North-eastern and Northern hill zones. It mainly grown in Chamba, Kangra, Mandi and Bilaspur districts of HP. The current investigation was conducted in kharif2022, at Research and Extension Centre, Gaja, College of Forestry, Ranichauri (Tehri Garhwal). The experiment comprised of two factors viz., fertility levels (F): F1- Control, F2- 75% NPK, F3- 100% NPK and F4- 125% NPK in main plot and genotypes (V): V1- EC0000264, V2- IC455396, V3- IC469174, V4- IC469175 and V5- HPU-51 in sub plot with total of 20 treatment combinations that were evaluated in split plot design with two replications. The seed after harvest were analysed for seed quality parameters in 2 factors complete randomized design with three replications at Department of Seed Science and Technology, College of Forestry, Ranichauri. The data was analysed using OP Stat with figures from SAS (proc glm). Among the fertility levels, F3 performed well in field conditions compared to others. Among various genotypes, V3 showed maximum growth with V2 having better yield attributes, yield and economics of adzuki bean as compared to other genotypes. On the basis of laboratory experiments, F3 performed well as compared to other fertility levels. Among different genotypes, V3 showed significant results over others. Also, the interactions between fertility levels and genotypes were found significant for quality parameters under standard germination and stress tolerance tests. Among all the traits, number of branches per plant exhibited highest GCV, PCV and ECV followed by grain yield, dry weight, number of pods per plant and fresh weight. High heritability was observed for fresh weight, biological yield and dry weight. High genetic advance was observed for test weight followed by fresh weight and harvest index. For genetic advance per cent mean, the maximum was found in seed yield, while minimum in plant height. High heritability coupled with high genetic advance indicates the presence of high additive gene effects providing scope for the improvement through hybridization and selection. Based on the study, it can be concluded that application of recommended fertilizer (100% NPK) enhances the growth, seed yield and economic of adzuki bean ofV2 (IC455396) genotypeand seed quality ofV3 (IC469174) of adzuki bean.

    (College of Forestry, Ranichauri, 2023) Rawat, Anchal; Kumar, Ajay(Dr.); Paliwal, Arunima(Dr.) (Member); Kumar, Pankaj (Dr.) (Member); Rawat, Deepa(Dr.) (Member)
    Title:“Seed quality enhancement of Asian spiderflower (Cleome viscosa Linn.) through chemical priming” The Cleome viscosa Linn.is an annual herb and a condiment plant which is locally known as “jakhiya” in hills of Uttarakhand and globally as Asian spider flower. The seed quality and germination of older and freshly harvested seeds of Cleome viscosa Linn.were recorded poor due to dormancy and other factors. Therefore, the research was planned to assess the seed quality and chemical priming in two lots of Asian spiderflower genotypes. The seed quality assessment experiment was conducted in FRBD (factorial randomized block design), which comprised of three factors viz. two seed lots (2021 and 2022), two temperatures (300C and 260C) andfour genotypes of Asian spiderflower (GPPA, GPUT, GPCH and GPTE) in three replications. The other seed quality assessment tests like physiological, bio-chemical and stress tests were also conducted in FRBD which comprised of two factors viz. two seed lots (2022, and 2021) and four genotypes (GPPA, GPCH, GPUT and GPTE) in three replications.The three seed quality enhancement experiments were conducted separately toassess the different chemical priming to enhance the seedqualityofCleome viscosa Linn. genotypes inthree FRBD with three replications viz, seed lots(2022and2021), genotypes (GPPA, GPCH, GPUT and GPTE) and chemical priming either with KNO3 (0.20g/l, 0.50g/l and 1.0 g/l) or CaCl2 (1%, 3% and 4%) or salicylic acid (0.1mM, 0.5mM and 1.0mM). In each experiment the data were recorded for germination percentage, seedling length, fresh weight, dry weight, seedlingvigourindices. The seeds of all genotypes of two lots were found viable. The average germination percentage recorded 24.9% and 32.2% in 2021 and 2022 seed lot respectively. The significantly higher standard germination was recorded at 300C than 260C. The physical seed quality tests viz. test weight, moisture content and bio-chemical testslike electrical conductivity wererecordedsignificantlyhigherin2021than2022seedlot. The other seed quality attributes viz. germination percentage, mean daily germination, seedlingfresh and dry weight and seedling vigour indices under standard germination test and stress test were recorded significantly higher in 2022 seed lot of Cleome viscosa Linn. than 2021 seed lot. GPCH recorded significantly higher seed quality parameters which were statistically at par with GPUT than GPPA. The germination percentage, seedling length, fresh weight, dry weight, seedlingvigourindex-I andII of all genotypes under both the seed lots were improved by chemical priming with 1.0g/l KNO3 or 3% CaCl2 or 1.0 mM of salicylic acid for 24 hours which were found to be effective than standard germination. The GPCH genotype had recorded significantly higher germination parameters which were statistically at par with GPUT than GPPA. Based on the present investigation, the freshly harvested seeds should be preferred to grow Asian spiderflower crop over older seeds. On the basis of seed quality parameters,GPCH and GPUT of 2022 seed lot were found mostsuitable genotypes totake a good crop of Asian spiderflower. The chemical priming of either KNO3 at 1.0g/l or CaCl2at 3% or salicylic acid at 1.0mM for 24hourswas recommendedto improvegermination and vigourof Asian spiderflower (Cleome viscosa Linn.). If farmer had one year old seed, the chemical priming with salicylic acid at 1.0mM for 24hoursshould be recommended for better germination of crop and germination establishment.

    Title: “Seed quality of quinoa (Chenopodium quinoa Willd.) influenced by geometry and fertility levels” Quinoa (Chenopodium quinoa Willd.) is a native of the Andes that has sparked a worldwide interest due to its unique nutritional value.It is characterised as pseudo-cereals crops, with broad leaf plant and starchy dicotyledonous seed and consequently not a cereal. It can be used as a substitute for dairy proteins. Quinoa seed have an orthodox magnificent nutritional food quality and were also called “the mother grain”. Furthermore, the quinoa plant is cold, salt and drought resistant, which is why it is known as the "golden grain”. The current investigationwas conducted in kharif2022, withgenotype “EC507742” at Research and Extension Centre, Gaja, College of Forestry, Ranichauri (Tehri Garhwal). The experiment comprised of two factorsviz., geometry (S): S1-20 x10 cm, S2-30 x 10 cm and S3-40 x 10 cm in main plot and fertility levels (F): F1- Control, F2- 75% NPKS, F3- 100% NPKS and F4- 125% NPKS in sub plot with total of 12 treatment combinations that were evaluated in split plot design with three replications.The seed obtained after harvest were analysed for seed quality parameters in 2 factors complete randomized design with three replicates at Department of Seed Science and Technology, College of Forestry, Ranichauri.The data was analysed using OPSTAT with figures from SAS (procglm). Among the geometry, S2 (30 x 10 cm) performed well in field conditions compared to others. Among various fertility levels, F3 (100% NPKS) showed maximum growth, yield attributes, yield and higher returnof quinoa as compared to other fertility levels. On the basis of laboratory experiments, wider spacing of S3 (40 x 10 cm) performed well as compared to other geometry. Among different fertility levels, F3 (100% NPKS) showed significant results over others.Also, the interactions between geometry and fertility levels were found significant for growth, yield attributes, yield and quality parameters under standard germination and stress tolerance tests. Based on the study, it can be concluded that application of recommended fertilizer (100% NPKS) with optimum spacing of 30 x 10 cm enhances the growth, yield and higher return of quinoa and with wider spacing of 40 x10 cm enhances the seed quality of quinoa.
