    (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.

    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.

    Field experiments were conducted under loamy sand soil during rabi seasons of 2020- 21 and 2021-22 at the Horticulture farm, S.K.N. College of Agriculture, Jobner. The experiment comprising six treatments of nitrogen management through organic manure, inorganic fertilizer and biofertilizer (100 % inorganic fertilizer without biofertilizer, 100 % inorganic fertilizer with biofertilizer, 75 % inorganic fertilizer, 25 % organic manure without biofertilizer, 75 % inorganic fertilizer, 25 % organic manure with biofertilizer, 50 % inorganic fertilizer, 50 % organic manure without biofertilizer and 50 % inorganic fertilizer, 50 % organic manure with biofertilizer) were assigned to main plots and four levels of nano urea (0, 25, 50 and 75 ml/ha) in sub plots and replicated thrice in split plot design. Garlic variety ‘G 282’ was used as a test crop. On the basis of two year results, application of 100 % inorganic fertilizer and biofertilizer combined with foliar spray of 75 ml/ha nano urea was proved the most superior treatment combination in garlic representing the significantly higher net returns (` 482860/ha) and bulb yield (194.80 q/ha). However, application of 75 % inorganic fertilizer, 25 % organic manure and biofertilizer combined with foliar spray of 50 ml/ha nano urea was also found equally effective treatment combination and fetched at par bulb yield and net returns. Based on response studies, foliar spray of 66 ml/ha nano urea was found to be the optimum level of N for garlic crop. Further, it may be concluded that application of 75 % RD through inorganic fertilizer, 25 % organic manure and biofertilizer combined with foliar spray of 66 ml/ha nano urea is worth recommendable for farmers of Rajasthan Zone IIIA under loamy sand soil to get significantly better yield (q/ha) net returns (₹) and maximum B:C ratio from garlic crop.
