    Studies on effect of plant growth regulators in polyhouse grown tomato (Solanum lycopersicum L.)
    (palampur, 2021-09-12) juma, Muhammad; Sharma, Parveen
    The present investigation entitled “Studies on effect of plant growth regulators in polyhouse grown tomato (Solanum lycopersicum L.)” was carried out at Vegetable Research Farm of the Department of Vegetable Science and Floriculture, CSK HPKV Palampur, Himachal Pradesh during spring-summer and autumn-winter season with the objectives to study the effect of different plant growth regulators on yield, quality and to work out the economics of production under protected conditions. The experiment was laid out in a Factorial Randomized Block Design with three replications and data were recorded on horticultural and quality traits in tomato. The recommended package of practices and plant protection measures were followed from time to time to grow healthy crop. Among the different plant growth regulators GA3 @75 ppm resulted maximum number of fruits per plant, fruit weight and marketable yield per plant, marketable yield per m2 area, ascorbic acid content plant height and minimum number of days to 50 % flowering. Highest fruit yield (27.65 kg/m2 ) with maximum net returns (394.00 /m2 ) and higher benefit: cost ratio (2.48) was obtained with the treatment combination involving T16 (GA3 @ 75ppm + All above three stages) during autumn-winter season. The combined effect of growth regulators at different stages of plant growth showed that A2B4 (GA3 @ 75 ppm sprayed at flowering stage) and A2B1 (NAA @ 50 ppm sprayed at flowering stage) recorded maximum (27.40 and 30.97 mg/100 g) ascorbic acid content for first and second season. The combined effect of growth regulators at different stages of plant growth showed that A2B4 (GA3 @ 75 ppm sprayed at flowering stage) recorded maximum (24.59 kg and 27.65 kg) marketable yield per m2 during both the seasons which was significantly superior from all other two-way interactions. Therefore, it has been concluded that tomato plants sprayed with GA3 @ 75ppm at flowering stage recorded maximum marketable yield and its contributing characters.

    Effect of methods and frequency of boron application on maize productivity and its use efficiency in an acid Alfisol
    (Palampur, 2021-08-13) Thakur, Pratibha; Kumar, Pardeep
    A field investigation was carried out during Kharif 2020 on maize (Zea mays L.) at the Nutrient Management Section of Department of Soil Science, COA, CSK HPKV, Palampur. The experiment comprised of fourteen treatments replicated thrice in a randomized block design (RBD) in order to figure out the efficacy of two methods of boron application (soil or foliar), foliar applications at three rates (0.017, 0.034 and 0.051%) and variable frequencies (two and three sprays). All these combinations received recommended dose of fertilizers. Basal application of boron @ 2 kg ha-1 through borax and three rates of foliar application i.e. half of recommended (0.017 %), recommended (0.034 %) and 1.5 times of recommended dose (0.051 %) with boric acid were tested. The foliar feeding of boron was done at knee height, tasseling and grain filling stages. The growth parameters, yield attributes and yield, nutrient uptake, boron use efficiency and soil properties were significantly affected by different boron treatments. The maximum grain yield (46.1 q ha-1 ) was recorded in the treatment where boron was supplied through conjoint soil and foliar application @ 2 kg ha-1 and 0.051 per cent (three foliar sprays), respectively which was 29.0 per cent higher than the boron deprived treatment. The highest boron use efficiency was recorded in the treatment that received sole foliar application of boron at recommended rate with two foliar sprays. The boron and micronutrient cations uptake by grains and stover were also enhanced when boron was applied and maximum uptake was recorded with conjoint soil and foliar application @ 2 kg ha-1 and 0.051 per cent, respectively, with three foliar feedings. Boron treatments had non significant effect on soil pH and organic carbon content, however, a significant effect was recorded in available N, P, K and B after harvest. Highest net returns of ₹ 53,448 ha-1 and benefit cost ratio (2.19) were registered when basal application of boron @ 2 kg ha-1 was supplemented with its three foliar feedings @ 0.051 per cent. The study highlight the importance of boron application in enhancing the maize productivity in acid soils.

    (Palampur, 2021-10-26) Kumar, Vikas; Singh, Ravinder
    The present investigation entitled “Evaluation of Colocasia (Colocasia esculenta L.) genotypes under natural farming condition” was undertaken at Research Sub Station, Berthin, Bilaspur during Kharif, 2020 in which 26 genotypes including Muktakeshi, used as standard check (SC), were evaluated in Randomized Complete Block Design (CRBD) with three replications to assess various parameters. The data was recorded on five competitive plants in each entry for corm yield and related horticultural traits. Based on the performance of local collections (LC); LC-10, LC-14 and LC-15 were the top three genotypes in exceeding the total yield performance with 162.40%, 89.56% and 77.89% over Muktakeshi (SC). The number of cormels per plant were maximum in LC-14 followed by LC-10 and LC-8, whereas, cormel length and diameter were highest in LC-12 and LC-15, respectively. Highest cormel and corm yield were recorded in LC-10 and LC-9, respectively, whereas, total yield was recorded highest in LC-10 followed by LC-14 and LC-15. Leaf length and breadth of LC-20 was highest, whereas, maximum leaf length and breadth ratio of LC-5 was observed. Number of leaves per plant were observed highest in LC-17 and the plant height was highest in LC-7. The minimum days were taken for 50% corm sprouting in Rajindra-1 followed by LC-18 and LC-24. In Muktakeshi and LC-12 lowest incidence of leaf blight disease was observed. Leaf area and leaf area index was highest in LC-17 and Muktakeshi, whereas, highest value of harvest index was recorded in LC-14. Genotypes investigated showed different shapes by visual observations. For quality attributes of colocasia, crude protein was highest in LC-3 followed by Muktakeshi (SC) and LC-1. The highest value for anthocyanin content was observed in LC-24, whereas, oxalate content was lowest in LC-15. Starch, sugar and total phenol content were highest in LC-7, LC-1 and LC-4, respectively. The promising genotypes identified on the basis of mean performance for corm yield and related traits under natural farming are LC-10 (collection from Baijnath of Kangra district, HP) for 10 traits, LC-15 (collection from Kolar of district Sirmour, HP) and LC-8 (collection from Gagret of district Una, HP) for six traits each and LC-14 (collection from Sarkaghat of Mandi district, HP) and LC-9 (collection from Bassi of Mandi district, HP) for five traits. Based on the performance of these genotypes, they can be utilized as source of germplasm in colocasia improvement program under natural farming conditions.

    Genetic assessment for fruit yield and component traits in bell pepper (Capsicum annuum (L.) var. grossum).
    (Palampur, 2021-12-09) Sharma, Tejal; Sood, Sonia
    The present research entitled “Genetic assessment for fruit yield and component traits in bell pepper (Capsicum annuum (L.) var. grossum)” was carried out at the Experimental Farm of Department of Vegetable Science and Floriculture, CSK HPKV, Palampur to collect information on nature and magnitude of gene action, combining ability effects, residual heterosis and inbreeding depression by following 6X6 half diallel involving six parental lines. Parents, their 15 F2 cross combinations along with standard check ‘California Wonder’ were evaluated in Randomized Complete Block Design (RCBD) with three replications during summer-rainy season of 2020. Data were recorded on fruit yield and component traits along with reaction to bacterial wilt disease. Sufficient genetic variability was present for all quantitative and quality traits. The diallel analysis revealed significant differences due to parents, crosses and parents vs crosses for majority of the traits indicating appreciable genetic diversity in the experimental material. Mean squares due to GCA and SCA were significant for all the traits studied. Among visually observed characters, light green, dark green, green, yellowish green and medium light green fruit colour at horticultural maturity, blocky fruit shape, cordate and lobate fruit shape at pedicel attachment, sunken, sunken and pointed fruit shape at blossom end, pendent, upright and intermediate fruit position and resistance reaction to bacterial wilt disease in all parents and cross combinations were recorded. Parents BWR-6-1, BWR-39 and EC-464107 were good general combiners for fruit yield and related traits. BWR-1 X EC-464107, BWR-29 X EC-464115 and BWR29 X EC-464107 were good specific combiners for fruit yield and component traits. Non-additive gene action was predominant for majority of the traits. Additive gene action was present for plant height, fruit length, fruit width and pericarp thickness. Average degree of dominance showed overdominance for days to 50 per cent flowering, harvest duration, fruits per plant, fruit yield per plant, marketable fruits per plant and marketable fruit yield per plant. Thus, the improvement of these characters would be effective through heterosis breeding. Significant amount of residual heterosis for fruit yield and component traits was exhibited by BWR-29 X EC-464107 and BWR-29 X EC-464115. Inbreeding depression was also present in the traits studied. Based on mean performance, SCA effects, residual heterois and inbreeding depression BWR-29 X EC-464107, BWR-29 X EC-464115 and BWR-1 X EC464115 were the most promising cross combinations for further exploitation. Pedigree method would be the effective future breeding strategy.

    (Palampur, 2021-09-14) B R, Sinchana; Chadha, Sanjay
    The present investigation was undertaken to study the effect of dates of sowing on different genotype of radish under organic and natural farming conditions. The trial was laid out in Split-split plot design comprising of three sowing dates (main plot factor) viz., 10th October, 25th October and 11th November, three sub-plot factor (farming conditions) viz., natural farming, organic farming and control and three sub-sub plot factors (varieties) viz., Him Palam Mooli-1, Palam Hriday and Japanese White; with three replications at the ‘Model Organic Farm’ of the Department of Organic Agriculture and Natural Farming, CSKHPKV, Palampur during Rabi 2019-20. The main objectives of the study were to evaluate different genotypes of radish under varied sowing dates and production system, and to study the economics of different treatments. The data were observed on different horticultural and quality traits along with economic indices parameters viz., number of leaves per plant, root length (cm), root diameter (cm), fresh weight of roots (g), shoot length (cm), fresh weight of leaves per plant (g), total fresh weight of plants (g), root-shoot ratio, number of marketable roots per plot, root yield per plot (kg), gross yield per plot (kg), gross yield per hectare (q), total soluble solids (0Brix), dry matter content of leaves (%), dry matter content of roots (%), gross returns, net returns and benefit-cost ratio. Crop sown on 10th October was observed significantly superior in all growth, qualitative, yield parameters and economics followed by 25th October. Among farming condition, Organic farming condition showed superiority over natural farming and control conditions for root length, root diameter, fresh weight of roots, shoot length, total fresh weight of plants, root-shoot ratio, dry matter content of leaves, dry matter content of roots, yield per plot, gross returns and net returns but benefit-cost ratio was maximum in natural farming condition. The cumulative interaction effect among sowing dates, farming conditions and varieties revealed that variety Japanese White sown on 10th October under natural farming conditions (S1F1V3) gave the highest net returns and benefitcost ratio of ₹633983/ha and 9.18, respectively. The second most remunerative treatment combination was S1F1V1 i.e., Him Palam Mooli-1 sown on 10th October under natural farming condition which gave net returns and benefit-cost ratio to the tune of ₹ 593823/ha and 8.60, respectively.

    (Palampur, 2021-11-30) Thakur, Shipra; Katoch, Viveka
    The present investigation was undertaken to optimize the spacing and nutrient requirement of the newly developed powdery mildew resisitant pyramid line of garden pea, Line 1-2. The experiment comprising of 12 treatments i.e. three spacings (30×10 cm, 45×10 cm and 60×10 cm) and four fertility levels viz. 100% recommended dose of fertilizer, 75% recommended dose of fertilizer, 125% recommended dose of fertilizer and 50% N through FYM + 50% N through urea + 100% PK and Azad Pea-1 as standard check was conducted in randomized block design with three replications at the Research Farm of Department of Vegetable Science and Floriculture, CSKHPKV, Palampur for two consecutive years during rabi 2019-20 and rabi 2020-21. Both spacings and fertility levels significantly influenced the yield and majority of its attributing traits. Spacing of 45×10 cm resulted in maximum number of primary branches per plant, number of nodes per plant, pod yield per hectare, pod length, number of seeds per pod, gross returns, net returns and benefit cost ratio. Among ferility levels, 125% RDF was the most promising fertility level for number of pods per plant, pod yield, shelling percentage and protein content. Seed yield and returns were highest in 100% fertility level. Quality traits viz. TSS and ascorbic acid content were recorded highest at 50% N through FYM +50% N through urea + 100% PK. Interaction effects between spacings and fertility levels revealed that sowing of Line 1-2 at spacing of 45×10cm with application of 100% recommended dose of fertilizer had significantly higher pod and seed yield, pods per plant and provided maximum returns, whereas 50% N through FYM +50% N through urea + 100% PK got second rank. Line 1-2 outperformed the standard check Azad Pea-1 for yield and yield attributing traits, returns and benefit cost ratio at 100% recommended dose of fertilizer( 25:60:60 + 20t/ha FYM) and spacing of 45 ×10cm.

    (Palampur, 2021-10-26) Sharma, Shimalika; Sharma, Akhilesh
    The present investigation was undertaken to evaluate the morphological and molecular diversity among the garden pea genotypes during winters 2019-20 and 2020-21. The experimental material comprising of 56 genotypes was evaluated in randomized completeblock design with three replications and data were recorded on pod yield per plant along with component traits. Sufficient genetic variability was observed for all morphological, yield and yield contributing, and quality traits during both the years of 2019- 20 and 2020-21. Genotypes SP-6, SP-22, SP-3, 2018/PMVAR/1 and 2019/PMVAR/1 were observed to be top ranking five promising genotype on the basis of yield and related traits. High heritability coupled with high genetic advance was observed for pod yield per plant which revealed the importance of additive gene action and phenotypic selection would be effective for improvement in the early generations. Correlation and path coefficient analysis revealed that pods per plant, average pod weight, shelling (%) and seeds per pod could be considered as the best selection parameters for evolving high yielding genotypes. The multivariate analysis revealed considerable genetic diversity present in the 56 genotypes studied and were arranged into 8, 5 and 6 clusters in 2019-20, 2020-21 and pooled over years, respectively. Number of pods per plant contributed maximum towards total genetic divergence during both the years and pooled over years, respectively. By virtue of desirable characters as well as maximum inter-cluster distance genotypes SP-6, SP-3, SP-22, SP-12, SN-8-2, DPPMFWR-30, Pusa Shree, Matar Ageta, Palam Triloki, Palam Priya, SN-2, SP-18, 2019/PMVAR/6 and Palam Sumool were identified. Molecular diversity analysis using UPGMA method indicated the presence of considerable diversity in the population as genotypes were grouped into two main clusters. Twelve genotypes viz., 2019/PMVAR/1, 2019/PMVAR/7, 2017/PMVAR/5, 2018/PMVAR/1, 2017/PMVAR/6, 2018/PMVAR/5, Pb89, SN-5, SP-18, SN-6, SP-10 and SN-10 were found common while comparing morphological and SSR data and, thereby exhibiting the consonance between morphological and SSR data. These genotypes offera scope for utilization in hybridization as parents for the isolation of transgressive segregants in garden pea.

    (Palampur, 2021-11-25) Rana, Sheetal; Sood, Sonia
    The present investigation entitled “Genetic evaluation and characterization of induced mutants of okra (Abelmoschus esculentus (L.) Moench)” was undertaken with the objective of getting the information on magnitude of genetic variability present among pod yield and component traits, characterization of induced mutants on the basis of different descriptors and to identify superior mutants. The experiment was undertaken in 25 mutants, six checks including parent variety P-8 and one inbred line 9801 evaluated in Randomized Complete Block Design with three replications at Experimental Farm of Department of Vegetable Science and Floriculture, CSK HPKV, Palampur during summer-rainy season, 2020. Data were recorded on days to 50 per cent flowering, days to first picking, plant height (cm), number of primary branches per plant, duration of availability of edible pods (days), node at which first pod set, nodes per plant, internodal length (cm), pod length (cm), pod diameter (cm), average pod weight (g), pods per plant, pod yield per plant (g), mucilage (%) and dry matter (%). The analysis of variance revealed significant differences among mutants for all quantitative and quality traits along with disease reaction studied. The maximum pod yield per plant was observed in mutant 16/3 (244.90 g) followed by 29/2 (237.94 g), 6/1 (231.51 g), 22/4 (218.47 g) and 24/7 (202.04 g). The estimates of PCV and GCV were highest for primary branches per plant, mucilage content, node at which first pod set and internodal length depicting the presence of substantial variability. High heritability coupled with high genetic advance was observed for primary branches per plant, mucilage content, pod yield per plant and internodal length revealing the importance of additive gene action. Hence, these characters could be improved through direct selection. Among visually observed characters, immature pod colour, intensity of pod colour, pod : pubescence, pod : surface between ridges, pod : constriction of basal part, pod : shape of apex, pod : number of locules, leaf blade : depth of lobing and leaf blade : dentation of margin were recorded. Based upon correlation and path-coefficient analysis, nodes per plant, pod length, average pod weight and pods per plant could be considered as the reliable selection parameters for evolving high yielding mutants. On the basis of overall performance, mutants 16/3 and 29/2 were observed to be promising for pod yield per plant coupled with traits viz., nodes per plant, internodal length, node at which first pod set and pods per plant. They also exhibited green immature pod colour with medium intensity of green colour, downy pubescence, flat surface between ridges, narrow acute apex shape, five number of locules and medium dentation of margins revealing thereby, theses mutants are most desirable for further selection. Among top yielding mutants, 29/2 and 6/1 were the only mutants which also exhibited excellent quality traits viz., mucilage (1.43%) and dry matter (9.39%), respectively along with cercospora leaf spot disease resistance. These mutants can be directly used after multi-location testing
