    Effect of Plant Growth Regulator and Growing Media on Growth of Root and Shoot in Dragon fruit [Hylocereus undatus L.]
    (2022) Dengri, Dollshree; L.N. Bairwa
    An experiment entitled “Effect of Plant Growth Regulator and Growing Media on Growth of Root and Shoot in Dragon fruit [Hylocereus undatus L.]” conducted during August – November 2021 in shade net house of Horticulture farm, S.K.N. College of Agriculture, Jobner- Jaipur (Rajasthan). The experiment was laid out in Factorial CRD and replicated three times with 16 treatment combinations including four plant growth regulator (IBA) concentrations (control, 2000, 4000 and 6000 ppm) and four growing media (control, sand : cocopeat, sand : vermicompost and sand : vermicompost : cocopeat). The result revealed that the dragon fruit cuttings treated with IBA at 6000 ppm performed superior in all the parameters viz., least number of days taken for root initiation (15.06 days), maximum percentage of rooted cuttings (85.88%), length of longest root (20.60 cm), average length of roots per cutting (13.52 cm), average number of roots per cutting (22.15), diameter of root (1.38 mm), least days taken for sprouting (25.03 days), percentage sprouting (59.98%), sprouts per cutting (2.35), shoot length per cutting (14.80 cm) and diameter of shoot (36.99 mm) at 75 days of planting, where IBA at 4000 ppm was reported at par with 6000 ppm of IBA. Similarly, sand : vermicompost: cocopeat (1 : 1: 1) growing media showed significantly higher results for all parameters viz., least number of days taken for root initiation (15.04 days), maximum percentage of rooted cuttings (85.81%), length of longest root (20.05 cm), average length of roots per cutting (13.28 cm), average number of roots per cutting (22.16), diameter of root (1.35 mm), least days taken for sprouting (25.01 days), percentage sprouting (59.53%), sprouts per cutting (2.35), shoot length per cutting (14.80 cm), diameter of shoot (36.47 mm) at 75 days of planting. Dragon fruit stem cuttings treated with 6000 ppm of IBA and grown in sand: vermicompost: cocopeat (1 : 1 : 1) media proved significantly superior combined treatment in maximum average root (17.14 cm) and shoot (18.64 cm) length. The maximum net return (₹ 854.94 per bed) and B:C ratio (2.21) was recorded under treatment combination G2M2 (IBA at 4000 ppm + sand : vermicompost) which was found to be significantly superior over the rest of the treatment combinations.

    Effect of Organic Manures and Mulching on Growth, Yield and Quality of Radish (Raphanus sativus L.)
    (2022) Rathore, Pooja; S.P. Singh
    A field experiment entitled „„Effect of Organic Manures and Mulching on Growth, Yield and Quality of Radish (Raphanus sativus L.)” was conducted during Rabi season 2021-22 at Horticulture Farm, S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan). The experiment comprised of sixteen treatment combinations including four treatments of organic manures (Control, FYM @ 9 t/ha, vermicompost @ 3 t/ha and poultry manure @ 3.6 t/ha) and four treatments of mulching (Control, saw dust @ 10 t/ha, plastic mulch and wheat straw @ 5 t/ha) were taken in Factorial Randomized Block Design with three replications. The results of the study clearly indicated that application of O2 (Vermicompost @ 3 t/ha) significantly increased the plant height (17.28 and 31.19 cm), number of leaves per plant (6.41 and 12.46) at 30 and 45 DAS respectively, leaf area (272.00 cm2 ), chlorophyll content (1.76 mg/g) in leaves, root diameter (6.13 cm), length of root (25.03 cm), shoot weight (48.00 g), root weight (128.48 g), shoot : root ratio (2.63), root yield (9.52 kg/plot and 264.54 q/ha), ascorbic acid content (12.95 mg/100g), net returns (Rs 282606/ha) and B:C ratio supervision of Dr. S.P. Singh, Assoc. Professor, Department of Horticulture, S.K.N. College of Agriculture, Jobner. (2.47) except treatment O3 (Poultry manure @ 3.6 t/ha), which was statistically at par with O2 in terms of net returns. Similarly, application of M2 (Plastic mulch) significantly increased the plant height (17.66 and 31.66 cm), number of leaves per plant (6.42 and 12.43) at 30 and 45 DAS respectively, leaf area (270.44 cm2 ), chlorophyll content (1.78 mg/g) in leaves, root diameter (6.21 cm), length of root (24.89 cm), shoot weight (48.34 g), root weight (128.51 g), shoot : root ratio (2.65), root yield (9.69 kg/plot and 269.31q/ha), ascorbic acid content (12.60 mg/100g). However, application of M3 (Wheat straw @ 5 t/ha) gives higher net returns (Rs 280068/ha) and B:C ratio (2.62) except treatment M2 (Plastic mulch), which was statistically at par with M3 in terms of net returns. Further, the combined application of O2M3 (Vermicompost @ 3 t/ha with Wheat straw @ 5 t/ha) were proved to be significantly superior in terms of net returns (Rs 333640/ha) and B:C ratio (3.06). Thus, on the basis of net returns and B:C ratio combined application of O2M3 (Vermicompost @ 3 t/ha with Wheat straw @ 5 t/ha) is worth recommended to fetch maximum net returns per hectare from radish.

    Effect of Organic Manures and Micronutrients on Root Yield and Seed Production of Carrot (Daucus carota L.)
    (2022) DHAKA, ASHA; Yadav, D.K.
    A field experiment was conducted to study the „„Effect of Organic Manures and Micronutrients on Root Yield and Seed Production of carrot (Daucus carota L.)” during rabi season 2021-22 at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Raj.). The experiment consisted of sixteen treatment combinations including four organic manures (no manure, FYM @ 10 t/ha, vermicompost @ 3.5 t/ha and poultry manure @ 2.5 t/ha) and four foliar spray of Micronutrients (control, FeSO4 @ 0.5 %, Borax @ 0.5% and ZnSO4 @ 0.5 %) were under taken in factorial randomized block design with three replications. The results of the study clearly indicated that application of poultry manure @ 2.5 t/ha to carrot significantly increased the plant height (cm), number of shoots per plant, chlorophyll content in leaves, days to 50% umbel initiation, average weight of marketable root (g),diameter of roots (cm),length of roots, shoots : roots ratio, core diameter (cm), roots yield (q/ha), number of umbels per plant, number of seed per umbel, diameter of umbel, seed weight per plant, days to seed maturity and seed yield per hectare(q/ ha) ,carotene content in roots, sugar content in roots, test weight of seed and net returns ( 334519/ha) and B:C (3.22) ratio of roots yield and net return ( 395741 ) and B: C (3.81) ratio of seed yield seen as for compared to control and FYM @ 10 t/ ha which was statistically at par with vermicompost @ 3.5 t/ha except net return and B:C ratio of root yield . Similarly, application of ZnSO4 @ 0.5 per cent as foliar spray significantly increased the plant height (cm), number of shoots per plant, chlorophyll content in leaves, days to 50% umbel initiation, average weight of marketable root (g), diameter of roots (cm), length of roots, shoots : roots ratio, core diameter (cm), roots yield (q/ha), number of umbels per plant, number of seed per umbel, diameter of umbel, seed weight per plant, days to seed maturity and seed yield per hectare( q/ha) carotene content (mg/ 100g) and sugar content (total sugar, reducing sugar and non – reducing sugar), net returns ( 340879/ha) and B:C ratio (3.50) of root yield and net returns( 400842/ha) and B:C (4.13) ratio of seed yield as compared to control and FeSO4 @ 0.5 percent which was statistically as per with borax @ 0.5 per cent except reducing sugar and net return and B:C ratio of root yield . Further, it can be concluded that combined application of poultry manure @ 2.5 t/ha with foliar spray of ZnSO4 @ 0.5 per cent proved to be the most superior treatment combination as it fetched comparable root yield (342.87 q/ha), seed yield (7.17 q/ha), net return ( 410334/ha) and B:C (3.95) ratio of root yield and net return ( 469393/ha) and B:C (4.51) ratio of seed yield
