Agriculture University, Kota

The Agriculture University, Kota (AUK) was established on 14th September, 2013 after bifurcation of the Maharana Pratap University of Agriculture & Technology (MPUAT), Udaipur and Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner through promulgation of Act No. 22 of 2013. The University has been created for the agricultural development in South-East and Eastern Rajasthan which is having diversified agriculture situations from rainfed to canal irrigated agriculture. The Agriculture University has its Headquarter at Borkhera Farm, Kota & is located on Kota-Baran National highway-76. Kota district is situated in the South-Eastern part of Rajasthan and comes under Humid South-Eastern Plain Zone (agro climatic zone V). It lies between 23045’ and 26038’ North latitude and 75037’ and 77026’ East longitude. The jurisdiction of AUK is spread over in 6 districts namely Kota, Baran, Bundi, Jhalawar, Karauli and Sawai Madhopur. It accounts for 9.98 % geographical area, 12.67 % total human population, 9.4 % live stock population, 31.59 % forest area and 20.6 % net sown area of the state. Development and education of modern practices in the field of Agriculture, Horticulture & Forestry for sustainable livelihood of the rural masses is the main thrust of the service area of AUK.

    Study on date of planting and size of bulblets on growth and yield attributes of kharif onion (Allium cepa L.) cv. Agrifound Dark Red
    (College of Horticulture and Forestry, Jhalawar, 2019-05-01) Kush, Amar; Maurya, I.B.
    A field experiment entitled “Study on date of planting and size of bulblets on growth and yield attributes of kharif onion (Allium cepa L.) cv. Agrifound Dark Red” was conducted during Kharif season, 2017-18 at the Department of Vegetable Science, College of Horticulture and Forestry, Jhalawar, Rajasthan. The experiment consisting 15 treatment combinations with two factors i.e. date of planting with five levels (20th July, 30th July, 10th August, 20th August and 30th August) and size of bulblets with three levels (1.5 to 2.0, 2.0 to 2.5 and 2.5 to 3.0 cm) was laid out in Factorial Randomized Block Design with three replications each. The individual application of date of planting treatment D2 (30th July) recorded maximum establishment of bulb (97.92 %), plant height (41.14 cm), numbers of leaves per plant (7.12), length of leaf (34.91 cm), width of leaf (0.79 cm), chlorophyll content in leaves at 45 DAP (0.57 mg/g), pseudostem length (4.72 cm), minimum neck diameter after harvest (0.96 cm) were recorded under D5 (30th August), average bulb weight (67.92 g), yield per plot (29.49 kg), estimated bulb yield (441.50 q/ha.), estimated marketable bulb yield (407.19 q/ha.), minimum un-marketable bulb yield (34.20 q/ha), percent marketable bulb yield A grade >3.5 cm (34.33), B grade 2.5 – 3.5 cm (24.92), minimum C grade 1.5 – 2.5 cm (12.63), polar diameter (4.44 cm), equatorial diameter (4.72 cm), TSS (12.52 °Brix), dry matter content (15.32 %) and minimum incidence to stem phylum/purple blotch (0.71) as compared to other treatment. The minimum day to maturity (118.11) were recorded under treatment D5 (30th August) and bolters (4.80 %), double bulb (1.13 %) and minimum incidence of thrips (1.92) were recorded under treatment D1 (20th July) as compared to other treatment. Similarly, the individual effect size of bulblets treatment B2 (2.0 to 2.5 cm) gave maximum plant height (40.38 cm), numbers of leaves per plant (7.27), length of leaf (35.37 cm), width of leaf (0.82 cm),chlorophyll content in leaves at 45 DAP (0.55 mg/g), psuedostem length (4.55 cm), minimum neck diameter after harvest (0.90 cm) recorded under B1 (1.5 to 2.0 cm), average bulb weight (62.79 g), yield per plot (24.49 kg), estimated bulb yield (408.12 q/ha), estimated marketable bulb yield (369.58 q/ha), minimum un-marketable bulb yield (38.47 q/ha), percent marketable bulb A grade >3.5 cm (33.73), B grade 2.5 – 3.5 cm (24.35), minimum C grade 1.5 – 2.5 cm (13.40), polar diameter (4.37 cm), equatorial diameter (5.06 cm), TSS (12.63 °Brix), dry matter content (14.72 %) minimum day to maturity (122.53), and minimum incidence to stem phylum/purple blotch (1.09) as compared to other treatment. Exhibited maximum establishment of bulb (97.51 %) individual effect of size of bulblets B3 (2.5 to 3.0 cm) and exhibited minimum bolters (4.14 %), double bulb (1.47) and incidence of thrips (3.72) individual effect of size of bulblets B1 (1.5 to 2.0 cm) as compared to other treatments. Further, the interaction effect of application of date of planting and size of bulblets had significant effect on growth and yield over the other treatment. The maximum number of leaves per plant (8.07), length of leaf (38.63 cm), average bulb weight (75.19 g), yield per plot (29.30 kg), estimated bulb yield (488.72 q/ha), estimated marketable bulb yield (454.66 q/ha), polar diameter (4.88 cm), equatorial diameter (5.37 cm ) was recorded under treatment D2B2 (30th July + 2.0 to 2.5 cm) and minimum neck diameter after harvest (0.84 cm) was recorded under treatment D5B1 (30th August + 1.5 to 2.0 cm) as compare to other treatment.
