    Effect of Seed Priming, Plant Bioregulators and Boron on Qualitative and Quantitative Performance of Bottle Gourd [Lagenaria siceraria (Mol.) Standl.]
    (Agriculture University, Jodhpur, 2024-04-06) Anupama; Moond, S.K.
    The present experiment entitled “Effect of seed priming, plant bioregulators and boron on qualitative and quantitative performance of Bottle gourd [Lagenaria siceraria (Mol.) Standl.]” was conducted under Randomized Block Design (RBD) with three replications using cultivar Pusa Naveen at the Instructional Farm and Laboratory of the Department of Horticulture, College of Agriculture, Jodhpur during summer seasons of 2020 and 2021. The research was conducted into two sub experiments. In the first experiment, the seeds of bottle gourd cultivar Pusa Naveen were primed with 7 different priming agents with 2 different soaking periods (12 and 24 hours) keeping unprimed seeds as control which consisted fifteen treatments i.e. Osmopriming with PEG 6000 @ -0.5 MPa for 12 and 24 hrs, Harmonal priming with GA3 @ 100 ppm for 12 and 24 hrs, Halopriming with Na2HPO4 @ 1% for 12 and 24 hrs, KH2PO4 @ 1% for 12 and 24 hrs, KNO3 @ 2% for 12 and 24 hrs and CaCl2 @ 2% for 12 and 24 hrs and Hydropriming with distilled water for 12 and 24 hrs and a control (untreated). It was found that seeds primed with GA3 @100 ppm for 24 hrs (T11) exhibited best results in terms of germination percentage (95.86%), speed of germination (7.25 days), field emergence (86.68%), speed of field emergence (5.22 days), seedling root length (12.04 cm), shoot length (19.74 cm), seedling length (31.78 cm), seedling dry weight (1.17 g), vigour index-I (2755) and vigour index- II (101.87) which was closely followed by PEG 6000 @-0.5MPa for 24hrs (T10) on the basis of pooled analysis. In the field study parameters, treatment of seeds with GA3 @100 ppm for 24 hrs proved to be the best treatment for characters like days to first female flower anthesis (57.46 days), 50 per cent flowering (58.23 days), vine length (5.56 m), number of primary branches (9.87), days to first picking (69.58 days), number of fruits per vine (8.63), fruit length (27.29 cm), fruit diameter (6.67 cm), fruit weight (682 g) and fruit yield per vine (6.07 kg/ha) and yield per ha (270.29 q) with maximum net returns (Rs.1,96,053) and B:C ratio (3.64). Amongst the various seed priming treatments, Bottle gourd seeds were primed with GA3 @100 ppm for 24 hours was rated as the most cost-effective treatment which produced the maximum fruit yield per hectare, net returns and B:C ratio. The second experiment consisted 21 treatment combinations i.e three plant bioregulators (Ethrel, NAA and GA3) with two different concentration and two levels of boron applied at 2 to 4 true leaf stage and 30 days after first spray during both the years. The results showed that borax 0.05% + ethrel 500 ppm (T11) significantly increased the plant growth, yield and quality parameters as compared to control treatment. On the basis of pooled analysis, the longest vine length (5.83 m) was recorded with the treatment borax 0.05% + GA3 50 ppm. The minimum number of days to first male flower anthesis (43.83 days), minimum days to first female flower anthesis (45.40 days), minimum days to 50 per cent flowering (46.05 days), minimum days to first picking (58.37 days), lowest number of node on which first female flower appeared (14.04), highest number of primary branches per vine (11.73), highest number of nodes on main vine (54.86), maximum number of fruits per vine (9.07), maximum fruit yield per vine (6.43 kg) and per hectare (286.15q/ha), maximum TSS (3.47 ᵒBrix) and ascorbic acid content (7.59 mg/100g) were recorded with borax 0.05% + ethrel 500 ppm (T11) which was statistically at par with the treatments borax 0.05% + NAA 100 ppm and borax 0.05% + NAA 200 ppm on pooled basis. The longest fruit (27.88 cm) with maximum diameter (6.95 cm) and the heaviest fruit weight (720 g) were recorded under the treatment borax @ 0.05% + NAA 200 ppm (T15) on pooled basis. Based on economics, borax @ 0.05% + ethrel 500 ppm was found to be more profitable in terms of net returns (Rs. 2,16,451 per ha) with highest B:C ratio (4.11) followed by foliar spray of NAA @100 and 200 ppm with borax @ 0.05%. On the basis of experimental findings, it is concluded that bottle gourd cv. Pusa Naveen sprayed with borax 0.05% + ethrel 500 ppm (T11) at 2 to 4 true leaf stage and 30 days after first spray provided the maximum income with a cost benefit ratio.

    (Agriculture University, Jodhpur, 2022-03-12) Kherwa, Radhe Shyam; Bhardwaj, Raju Lal
    An investigation was undertaken with a view to evaluate the magnitude of heterosis, combining ability, G x E interactions and stability parameters for fruit yield and its component characters following Line × Tester design involving (4 females and 8 males) varieties/genotypes of brinjal (Solanum melongena L.). These twelve parents and their 32 F1s with Pusa Uttam as standard check were tested for sixteen characters under three growing transplanting season. viz., E1: Summer Season – April, E2: Kharif Season – July, E3: Early Winter Season – October, in the year of 2020-2021, at Instructional Farm, College of Agriculture, Jodhpur, in randomized block design with three replications. The analysis of variance for all the traits revealed presence of considerable genetic variability in the genotypes studied. Appreciable influence of environment which showed the genotype × environment interaction was significant for all the characters. While the mean squares due to G × E interactions were significant for most of the traits. The most heterotic crosses over mid parent, better parent and standard check for fruit yield and other contributing characters were PR-5 × BCB-71-1, PR-5 × Swarna Mani, PLR-1 × Swarna Mani, PLR-1 × BCB-71-1, PLR-1 × BCB-464, PR-5 × BCB-464, VR-2 × CO-2, IIHR- 563 × BCB-71-1 and IIHR- 563 × BCB-464. These crosses were considered promising for their use for improvement of yield characters with earliness and quality traits in brinjal. The environment wise combining ability analysis revealed significant differences for gca and sca variances for all the characters indicating importance of both additive and non-additive gene effects in the genetic control of all the characters studied. The mean sum of squares due to females × environments (seasons) were significant for fruit yield which indicated that gca variance of females were influenced by the environments. The combining ability studies indicated that among female parents, PR-5, PLR-1 and VR-2, whereas among male parents BCB-464, BCB-71-1, Swarna Mani and CO-2 were emerged as good general combiners for fruit yield and most of the contributing characters. Whereas, the crosses viz., PR-5 × BCB-71-1, PR-5 × BCB 464, PLR-1 × BCB-71-1, PLR-1 × Swarna Mani, VR-2 × CO-2, IIHR- 563 × BCB 464 and VR-2 × Swarna Mani were exhibited high sca effect for fruit yield and most of the contributing characters. These crosses could be of immense potential in brinjal improvement programme. The analysis of variance of phenotypic stability indicated highly significant G × E interaction for most of the traits indicating differential response of genotypes to varied environments. The mean sum of squares due to pooled deviation (non-linear) were also significant for most of the characters indicating role of unpredictable causes affecting stability and the prediction of these attributes would be difficult. Joint consideration of mean performance and stability parameters revealed that parents BCB-464, BCB-71-1, PR-5, IIHR- 563, Swarna Mani and PLR-1 was more responsive for fruit yield and associated characters, therefore these were considered suitable for better environment. The crosses PR-5 × BCB-464, PR-5 × BCB-71-1, PLR-1 × BCB-71-1, PLR-1 × Swarna Mani, IIHR- 563 × BCB-71-1 and PLR-1 × BCB-464 was stable over wide range of environments for most of fruit yield traits with earliness and quality attributes, showing their suitability for variable environments. Overall, on the basis of high per se performance, significant gca effects for fruit yield with earliness as well as quality characters and stability, the parents PR-5, BCB-464, BCB-71-1, PLR-1 and Swarna Mani were found superior. Out of 32 crosses studied, PR-5 × BCB-464, PR-5 × BCB-71-1, PLR-1 × BCB-71-1, PLR-1 × BCB-464 and PLR-1 × Swarna Mani were found to have superior on the basis of high per se performance, sca effects, significant heterotic effect in desirable direction and good stability in all three environments as well as poled over environments for fruit yield and most of the associated traits like earliness and quality traits, offer good opportunity for future brinjal improvement programme.

    (Agriculture University, Jodhpur, 2023-08-19) Choudhary, Rajneesh; Moond, S.K.
    A field experiment was conducted on 10 genotypes of gladiolus (‘Suchitra’, ‘Gunjan’, ‘Jyotsna’,‘White Prosperity’, ‘Chandni’, ‘Pusa Shanti’, ‘Creamy Green’, ‘Rani’, ‘Green Spire’ and ‘Punjab Dawn’) in a Randomized Block Design with three replications, at the Instructional Farm, College of Agriculture, Jodhpur, during the Rabi season (November to April) of 2022-23, to study performance and expression of genetic variability of gladiolus genotypes under Jodhpur (Rajasthan) conditions. The performance of genotypes depicted that ‘White Prosperity’ were recorded tallest plants (107.33 cm), longest spikes (86.00 cm), maximum number of leaves per plant (10.30), leaf width (4.13 cm), leaf length (50.10 cm), spike diameter (0.87 cm), rachis length (66.00 cm), number of florets per spike (16.17), floret diameter (8.23 cm), number of cormels produced per plant (40.00), weight of cormels per plant (27.77 g) and vase life of spike (8.74 days). The genotype ‘Punjab Dawn’ yielded the highest number of spikes per plant (2.40) and higher spike yield of (157.57 thousand per hectare) amongst all the genotypes. The genotype ‘Chandni’ required the minimum days to spike emergence (59.41 days) and the minimum days to first floret opening from spike emergence (8.53 days). The genotype ‘Gunjan’ had the highest yield of corms per plant (2.94) and estimated corm yield per hectare (169.696 thousands) as well as maximum diameter of corm (4.71 cm) & weight of corm (59.00 g). Genetic variability among the genotypes was estimated in terms of range, GCV and PCV, and correlation among the 20 parameters of study was analysed. The number and weight of cormels produced per plant recorded high order estimates for GCV indicating that these characters were governed by the additive gene effects and hence, selection could be effective for their improvement. Analysis of variance exhibited significant differences for all the characters. Analyses of correlation, genotypic correlation was higher corresponding to phenotypic correlation for most of the parameters.

    (Agriculture University, Jodhpur, 2023-09-10) Nehra, Nitu; Choudhary, Santosh
    A field experiment on “Genetic Variability and Path Coefficient Analysis Study in Cauliflower (Brassica oleracea L. var. botrytis) Under Arid Climatic Conditions” was carried out during Rabi, 2022-23 at the Instructional Farm of the College of Agriculture, Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 16 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, the correlation between yield and other characters, the direct and indirect effect of yield contributing traits through path analysis. Significant differences in the analysis of variance for each attribute indicated that there are great inherent genetic variances among the genotypes. For each of the investigated traits, the phenotypic coefficient of variance was slightly greater than the corresponding genotypic coefficient of variation. High estimates of heritability and genetic advance as per cent of mean were observed for the characters viz., curd yield per plant followed by curd yield per plot, curd yield per hectare, ascorbic acid, days to 50% curd initiation, days to 50% curd maturity, plant height, leaf width, leaf length, curd circumference. The moderate heritability was recorded for SPAD Unit, curd width and plant spread. Correlation coefficient analysis among the traits studied revealed that curd yield per plant has a strong positive significant association with characters like plant height, plant spread, leaf length, leaf width, days to 50% curd initiation, days to 50% curd maturity, curd circumference, curd width, ascorbic acid and SPAD Unit. Path coefficient analysis of various quantitative characters indicated that cured width, days to 50% curd initiation, days to 50% curd maturity, ascorbic acid and curd circumference exhibited a positive direct effect on curd yield per plant while, plant height exhibited the maximum negative direct effect on curd yield per plant. Based on yield and yield attributes, among varieties Sabour Agrim and in hybrids Fortaleza were found superior and can be recommended for testing in large environments to check its suitability for growing in arid region of Rajasthan

    (Agriculture University, Jodhpur, 2023-09-13) Kalpana; Choudhary, Santosh
    A field experiment entitled “Effect or nano urea fertilization on growth yield and quality of Nagauri methi (Trigonella corniculata L.)” was carried out during Rabi season of 2022-23 at the College of Agriculture, Jodhpur. The experiment consisted 12 treatments viz., control, 2 ml/l nano urea, 4 ml/l nano urea, 50% RDN, 50% RDN + 2 ml/l nano urea, 50% RDN + 4 ml/l nano urea, 75% RDN, 75% RDN + 2 ml/l nano urea, 75% RDN+ 4 ml/l nano urea, 100% RDN,100% RDN + 2 ml/l nano urea and 100% RDN + 4 ml/l nano urea, and was laid out in Randomized Block Design (RBD) with three replications. The results of the study clearly indicate that application of 100% RDN + 4 ml/l nano urea recorded the highest plant height, number of branches per plant, internodal length, total number of cuttings and minimum number of days taken for first cutting and shortest average cutting interval over the control. The treatment 75% RDN + 4 ml/l nano urea remained at par with 100% RDN + 4 ml/l nano urea. Quality parameter of Nagauri methi like iron content of leaves, chlorophyll content, protein contents of leaves and seed were significantly higher with application of 100% RDN + 4 ml/l nano urea over the control and statistically at par with 75% RDN + 4 ml/l nano urea. The lowest values of these parameters were recorded with control treatment. The maximum fresh and dry herb yields and seed yield were recorded markedly higher with application of 100% RDN + 4 ml/l nano urea, being statistically at par with 75% RDN + 4 ml/l nano urea. The lowest values of these parameters were recorded with control treatment. Significantly higher net returns (₹ 322565/ha) and B:C ratio (3.05) were obtained with application of 75% RDN + 4 ml/l nano urea over the control followed by 100% RDN + 4 ml/l nano urea net returns (₹ 322540/ha) and B:C ratio (3.04). Hence, 75% RDN + 4 ml/l nano urea application can be beneficial for producing higher productivity and net returns of Nagauri methi in western Rajasthan.

    (Agriculture University, Jodhpur, 2023-09-25) Jat, Asha; Moond, S.K.
    The present experiment entitled “Effect of Water Regimes, Land Configurations and Mulching on Growth, Yield and Quality of Onion (Allium cepa L.)” was conducted at Instructional farm, College of Agriculture, Jodhpur during rabi season of 2020-2021 and 2021-2022. The experiment had 24 treatments in Split-Split Plot Design including three factors i.e., A) one main factor: water regime having three levels (I1 - 1.0 IW/CPE, I2 - 0.8 IW/CPE and I3 - 0.6 IW/CPE) and two sub factors B) land configuration having two levels (B1 - flat bed and B2 - raised bed) and C) mulching having four levels (M1 - no mulch, M2 - black mulch, M3 - silver-black mulch and M4 - white-black mulch). The 0.8 IW/CPE water regime substantially enhanced growth, yield and quality attributes of onion viz., plant height (50.26 cm), leaf length (45.01 cm), leaf diameter (18.93 mm), neck length (5.25 cm), number of leaves per plant (13.32), neck diameter (21.28 mm), time taken to maturity (114.77 days), bolting (1.68%), leaf chlorophyll content (19.25 µg/100g), leaf N content (173.68 mg/100g), leaf P content (42.09 mg/100g), leaf K content (224.54 mg/100g), leaf S content (0.44%), weight of fresh bulb (80.75 g), weight of cured bulb (72.15 g), polar diameter of bulb (5.32 cm), equatorial diameter of bulb (5.99 cm), number of bulb scales (11.49), thickness of bulb scale (2.58 mm), bulb yield (33.37 t/ha), dry matter content (17.35%), double bulb (1.90%), sulphur content (0.49%), allyl propyl disulphide content (6.92 µmol/g), weight loss (6.00%, 14.71% and 34.52% at 30, 60, 90 DOS, respectively) and bulb rotting (2.49% and 5.42% at 60 and 90 DOS, respectively) over 0.6 IW/CPE on the basis of pooled analysis. Additionally, significantly higher net returns (` 3,51,684 per ha) and B:C ratio (3.36) were also recorded with 0.8 IW/CPE. This treatment remained at par with 1.0 IW/CPE. However the maximum water use efficiency (67.98 kg/ha-mm) was recorded with 0.6 IW/CPE. The raised bed land configuration significantly improved growth, yield and quality attributes of onion viz., plant height (51.03 cm), leaf length (45.71 cm), leaf diameter (19.28 mm), neck length (5.32 cm), number of leaves per plant (13.49), neck diameter (22.04 mm), time taken to maturity (115.30 days), bolting (1.74%), leaf chlorophyll content (19.68 µg/100g), leaf N content (175.46 mg/100g), leaf P content (42.73 mg/100g), leaf K content (226.78 mg/100g), leaf S content (0.44%), weight of fresh bulb (82.04 g), weight of cured bulb (74.40 g), polar diameter of bulb (5.41 cm), equatorial diameter of bulb (6.13 cm), number of bulb scales (11.67), thickness of bulb scale (2.58 mm), bulb yield (34.14 t/ha), dry matter content (17.59%), double bulb (2.03%), sulphur content (0.49%), allyl propyl disulphide content (6.96 µmol/g), net returns (` 3,62,804 per ha), B:C ratio (3.43) and water use efficiency (63.31 kg/ha-mm) over the flat bed land configuration on pooled basis. The application of black mulch considerably enhanced the growth, yield and quality attributes viz., plant height (52.50 cm), leaf length (46.99 cm), leaf diameter (19.68 mm), neck length (5.51 cm), number of leaves per plant (13.79), neck diameter (22.15 mm), time taken to maturity (116.36 days), bolting (1.86%), leaf chlorophyll content (19.80 µg/100g), leaf N content (177.78 mg/100g), leaf P content (43.17 mg/100g), leaf K content (229.56 mg/100g), leaf S content (0.44%) weight of fresh bulb (82.64 g), weight of cured bulb (75.58 g), polar diameter of bulb (5.44 cm), equatorial diameter of bulb (6.29 cm), number of bulb scales (11.75), thickness of bulb scale (2.66 mm), bulb yield (34.47 t/ha), dry matter content (17.94%), double bulb (2.08%), sulphur content (0.49%), allyl propyl disulphide content (7.00 µmol/g), weight loss (6.08%, 15.12% and 35.48% at 30, 60, 90 DOS, respectively) and bulb rotting (2.58% and 5.59% at 60 and 90 DOS, respectively) over white-mulch and no mulch on the basis of pooled data, but remained at par with silver-black mulch. Moreover, significantly enhanced net returns (` 3,67,291 per ha), B:C ratio (3.45) and water use efficiency (63.91 kg/ha-mm) were also recorded with black mulch. The most profound interaction effect with the maximum neck diameter (24.89 mm), weight of fresh bulb (94.26 g), weight of cured bulb (85.23 g), polar diameter of bulb (6.24 cm), number of bulb scales (12.52), bulb yield (39.25 t/ha), net returns (` 4,38,927 per ha) and B: C ratio (3.93) was found with I1×B2 on pooled basis. Similarly, the most improved weight of fresh bulb (96.13 g), polar diameter (6.29 cm), bulb yield (39.99 t/ha), net returns (` 4,49,581 per ha) and B:C ratio (3.99) were observed with I1×M2 (being at par with I1×M3). The maximum weight of fresh bulb (90.35 g), weight of cured bulb (81.58 g), bulb yield (37.79 t/ha), net returns (` 416746 per ha), B:C ratio (3.77) and water use efficiency (69.37 kg/ha-mm) were observed in B2×M2 (being at par with B2×M3). The maximum weight of fresh bulb (110.83 g), bulb yield (46.59 t/ha) and net returns (` 5,48,071 per ha) were recorded under I1×B2×M2. Thus, based on pooled data analysis, it may be concluded that the application of 0.8 IW/CPE, raised bed land configuration and black mulch may be recommended for rabi onion cultivation under Agro-Climatic Zone IA (Arid Western Plains Zone) for higher yield of onion.

    (Agriculture University, Jodhpur, 2022) Kuri, Ronak; Choudhary, Santosh
    A field experiment was conducted at Instructional Farm, College of Agriculture, Jodhpur to assess the “Effect of zinc and iron application on growth and yield of garlic (Allium sativum L.)” during Rabi, 2021-22. The experiment comprised 13 treatments consisting of three levels each of ZnSO4 and FeSO4 at 5, 10 and 15 kg/ha as soil application and three levels of each as a foliar application at 0.3, 0.5 and 0.7% concentration at 60 and 90 DAP and control. The experiment was laid out in a randomized block design with three replications. The results revealed that all the growth parameters, yield parameters, quality attributes, and economics of garlic were influenced significantly by different levels of soil and foliar application of ZnSO4 and FeSO4. Among the different levels of Zn, soil application of ZnSO4@15 kg/ha and foliar application of ZnSO4@0.7% being at par with ZnSO4@10 kg/ha and ZnSO4@0.5%, respectively recorded significantly higher growth and yield attributes over control. Therefore, the growth and yield parameters under ZnSO4@15 and 10 kg/ha; and ZnSO4@0.7 and 0.5% were recorded statistically at par with each other. Further, among different levels of Fe, soil application of FeSO4@15 kg/ha and foliar application of FeSO4@0.7%, being at par FeSO4@10 kg/ha and FeSO4@0.5%, respectively recorded significantly higher growth and yield attributes over control. Similar to Zn levels, FeSO4@15 and 10 kg/ha, and FeSO4@0.7 and 0.5% recorded growth, yield and quality parameters statistically at par with each other. A significant residual effect of ZnSO4 and FeSO4 in soil was recorded with soil application of both nutrients. The highest net returns (`4,65,154/ha) were obtained from foliar application of ZnSO4@0.7%; whereas the highest B: C ratio (3.08:1) was obtained from soil application of ZnSO4@15kg/ha. Moreover, with soil and foliar application of FeSO4 highest net returns (`4,32,621/ha) and B: C ratio (2.84:1) were recorded with FeSO4@0.7% over control and other treatment of FeSO4. Hence, soil application of Zn and Fe by ZnSO4 and FeSO4@15 kg/ha or their foliar application at 0.7% concentration can be beneficial for producing higher productivity and net returns of garlic in western Rajasthan.

    The present investigation entitled “Effect of pre-sowing seed treatments on germination and seedling vigour of Ber (Ziziphus rotundifolia Lamk.)” was conducted at Nursery of Instructional Farm, College of Agriculture, Jodhpur, from February, 2022 to June, 2022. The experiment was laid out in completely randomized design with three replications with 18 pre-sowing seed treatments i.e., Sulfuric acid (30% concentration) soaking for 15, 30, 45 and 60 minutes, Gibberellic acid soaking @ 250 ppm for 12 and 24 hours, Gibberellic acid soaking @ 500 ppm for 12 and 24 hours, Potassium nitrate soaking @ 0.5%, 1.0%, 1.5% and 2.0% for 12 hours, Boiling water soaking for 5, 10, 15 and 20 minutes, tap water soaking for 24 hours and control. Amongst the different pre-sowing seed treatments, soaking with GA3 @ 250 ppm for 24 hours resulted in the highest germination at 45 DAS (48.91%) and 60 DAS (50.0%), shoot length of seedling at 60 DAS (52.40 cm) and 90 DAS (72.10 cm), root length of seedling (32.13 cm), number of primary roots per seedling (33.43), number of primary branches per seedling at 90 DAS (4.10), fresh weight of seedling (14.97 g), fresh weight (11.0 g) and dry weight (4.98 g) of shoot, fresh weight (3.94 g) and dry weight (2.0 g) of root, seedling survival (100%), Vigour Index-I (3605.0) and Vigour Index-II (300.0) at 90 DAS, collar diameter of seedling (2.78 mm and 4.44 mm), number of leaves per seedling (46.0 and 69.10), inter-nodal length (2.35 cm and 2.90 cm) and leaf size (4.90 cm2 and 6.0 cm2 ) at 60 and 90 DAS, respectively, with the highest net returns (1549.0) and B:C ratio (1.22) which was significantly superior than other treatments except while the earliest seed germination (21.90 days) was recorded with sulphuric acid soaking for 60 minutes treatment.
