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.

    Effect of water volumes and mulches on growth and development of sweet orange (Citrus sinensis Osbeck) cv. Mosambi
    (College of Horticulture and Forestry, Jhalawar, 2020) CHOUDHARY, KALPANA; Singh, Dr. Jitendra
    The present investigation entitled “Effect of water volumes and mulches on growth and development of sweet orange (Citrus sinensis Osbeck) cv. Mosambi” was conducted for two consecutive years (April, 2018 to March, 2020) at the Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The experiment consisting of 15 treatments comprising three levels of water volume (100% ETc, 80% ETc and 60% ETc,) and five levels of mulches (no mulch, black polythene mulch, transparent polythene mulch, coriander straw mulch and dry grass mulch) was laid out in Randomized Block Design with three replications. Amid different irrigation treatments, application of treatment T1 (100% ETc) was found significantly superior over all other treatments with respect to plant growth and development parameters including soil physical and chemical properties. The rootstock girth (36.61%), scion girth (36.85%), height of the plant (28.64%), canopy spread (E-W: 63.82%, N-S: 63.87%), number of internodes/shoot (1.95%), canopy volume (2.49%), number of shoots/branch (2.17%), number of nodes/branch (67.64%), number of leaves/shoot (67.65%), petiole length (48.84%), leaf length (59.52%), leaf width (59.92%), leaf area (2.30%), leaf perimeter (59.95%), leaf area index (1.84%), leaf chlorophyll content (2.40 mg/g) and leaf NPK content (N: 2.39%, P: 0.16%, K: 1.57%) increased significantly over all other treatments in T1 treatment. Whereas, better moderation in soil parameters like soil pH (7.24), electrical conductivity (0.39 dSm-1) and bulk density (1.34 mg.m-3) along with higher increase in organic carbon (0.53%), porosity (49.48%), water holding capacity (42.87%) available soil N (314.11 kg.ha-1), P (28.93 kg.ha-1) and K (291.53 kg.ha-1) was evident in treatment T1 (100 % ETc) in rhizosphere soils of the sweet orange plants. Amid different treatment of mulches, the plant height (30.31%), rootstock girth (37.90%), scion girth (38.95%), number of shoots/branch (2.18%), number of nodes/branch (73.00%), number of leaves/shoot (73.31%), number of internodes/shoot (1.97%), canopy spread (E-W: 67.56%, N-S: 67.90%), canopy volume (2.52%), petiole length (49.52%), leaf 150 length (62.68%), leaf width (63.83%), leaf area (2.34%), leaf perimeter (64.01%), leaf area index (1.88%), leaf chlorophyll content (2.41 mg/g) and leaf NPK content (N: 2.40%, P: 0.17%, K: 1.59%) were noted significantly maximum under M1 treatment (Black polythene mulch). Soil parameters such as pH (7.25), electrical conductivity (0.39 dSm-1), bulk density (1.33 mg.m-3) moderated better besides organic carbon (0.54%), porosity (49.93%), water holding capacity (43.67%) available soil N (315.70 kg.ha-1), P (29.38 kg.ha-1) and K (293.19 kg.ha-1) increased significantly higher in treatment M1 (Black polythene mulch) as compared to other treatments in soils of rhizosphere of sweet orange plants. As regard to interaction of treatments, though all plant parameters were found significantly higher in treatment T1M1 (100% ETc with black polythene mulch) but treatment T2M1 (80% ETc with black polythene mulch) was recorded at par with it. In treatment T2M1 per cent increase in shoot parameters like rootstock girth (41.68%), scion girth (42.80%), height of plant (32.77%), canopy volume (2.58%), canopy spread (E-W: 72.98%, N-S: 73.05%), number of internodes/shoot (2.02%), number of leaves/shoot ( 81.19%), number of nodes/shoot (80.68%) and number of shoots/branch (2.21%); leaf parameters like leaf length (67.37%), leaf width (67.87%), leaf area (2.39%), leaf perimeter (68.68%), leaf area index (1.91%), leaf chlorophyll content (2.47 mg/g) and leaf NPK content (N: 2.45%, P: 0.18%, K: 1.66%) was noted at par with T1M1 (100% ETc with black polythene mulch). Further, in this treatment (T2M1) moderation in soil pH (7.18), electrical conductivity (0.37 dSm-1) also bulk density (1.31 mg.m-3) and increase in organic carbon (0.56 %), porosity (50.26 %), water holding capacity (45.02 %) also available soil N (320.19 kg.ha-1), P (30.94 kg.ha-1) and K (298.54 kg.ha-1) was at par with the treatment T1M1 (100 % ETc with black polythene mulch). On the basis of present investigation carried out for two consecutive years (April, 2018 to March, 2020) it may be concluded that among the irrigation treatments T1 (100% ETc); amid mulching treatment M1 (Black polythene mulch) and betwixt the combination of treatments T2M1 (80% ETc with black polythene mulch) proved significant impact on plants and soil parameters in Mosambi orchard as well. In this treatment T2M1 (80 % ETc along with black polythene mulch) total saving of water was worked out as 78979.8 liters/ha as comparied to treatment T1M1 (100 % ETc along with black polythene mulch).
