Agriculture University, Jodhpur

Agriculture University, Jodhpur was established on 14th September, 2013 by Government of Rajasthan under Agriculture University, Jodhpur Act 21 of 2013 to focus on holistic development of arid and semi-arid regions of the state covering 6 districts (Jodhpur, Barmer, Nagaur, Pali, Jalore and Sirohi), constituting 28% of total geographical area which is sustaining 20.8% human and 28.4% animal population of the state. The districts under jurisdiction of the university cover 3 agro-ecological zones of the state. These are Arid Western Plain Zone Ia (Jodhpur and Barmer districts), Transitional plain of Luni Basin Zone IIb (Jalore, Pali, and Sirohi districts) and part of Transitional Plain of Inland Drainage Zone IIa (Nagaur district). The university has 1 institute of diploma and 3 colleges to produce highly competent educated human resources in agriculture and allied sciences besides 2 agricultural research stations, one each in zone Ia & IIb and 3 agricultural research sub stations, one in each zone to prepare, plan and perform highly need based research in this acute water scarce but naturally rich bio-diversified zone of the country. The third most important part in tri-pillar (Teaching, Research & Extension) of agricultural development, the extension for transfer of technologies are reached to doorsteps of the farming community by 6 Krishi Vigyan Kendras (K-V-Ks), 2 in Nagaur district and 1 each in Jodhpur, Barmer, Jalore & Sirohi districts under the umbrella of the university. The different units of teaching, research and extension are coordinating to systematically run by the headquarter situated at Mandor, Jodhpur.

    Effect of Nano Fertilizers on Productivity of Wheat (Triticum aestivum L.)
    (Agriculture University, Jodhpur, 2024-03-16) Borana, Hitesh; Singh, Ishwar
    A field experiment was carried out to study the “Effect of nano fertilizers on productivity of wheat (Triticum aestivum L.)” at Instructional Farm, College of Agriculture, Jodhpur (Agriculture University, Jodhpur, Rajasthan) during Rabi seasons of 2021-22 and 2022-23. The field experiment was laid out in randomized block design (RBD) with fourteen treatments replicated thrice. The treatments comprised of T1-100% RDF + two foliar spray of nano N at 35 & 55 DAS, T2-100% RDF + foliar spray of nano P at 35 DAS, T3-100% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T4-75% RDF + two foliar spray of nano N at 35 & 55 DAS, T5-75% RDF + foliar spray of nano P at 35 DAS, T6- 100% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T7-50% RDF + two foliar spray of nano N at 35 & 55 DAS, T8-50% RDF + foliar spray of nano P at 35 DAS, T9-50% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T10-Foliar spray of nano P at 35 DAS + two foliar spray of nano N at 35 & 55 DAS, T11-ST with nano P at 5 ml/kg seed + foliar spray of nano P at 35 DAS + two foliar spray of nano N at 35 & 55 DAS, T12- ST with nano P at 5 ml/kg seed + two foliar spray of nano N at 35 & 55 DAS, T13- 100% RDF through conventional fertilizers and T14-Control. Findings based on pooled analysis indicate that the highest plant height (93.5 cm) and dry matter accumulation (1004.7 g/m2 ) at harvest stage were recorded with the application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS which was statistically at par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Similarly, the highest values of CGR between 40-80 DAS (16.40 g/m2/day) and 80 DAS-at harvest (3.86 g/m2/day) were also recorded with application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS, on pooled basis. Application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS substantially improved yield attributing characters viz., number of tillers/m2 (431), no. of spikes/m2 (414), spike length (17.03 cm), no. of grains/spike (45.24) and test weight (46.32 g) over control. Application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS recorded significantly higher grain yield (4,399 kg/ha), straw yield (5,525 kg/ha) and biological yield (9,923 kg/ha) and crude protein content (10.45%) over control on pooled basis. Considerably higher N (25.97 & 83.10 kg/ha) and P (4.39 & 19.81 kg/ha) uptake by wheat plant at 40 & 80 DAS were recorded under application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS over control, respectively. However, it remained at par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Significantly higher nitrogen and phosphorus uptake by grain (80.63 & 15.39 kg/ha) and straw (27.99 & 10.47 kg/ha) were recorded by 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS over control, on pooled basis. Post-harvest soil fertility analysis of wheat crop revealed that application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS significantly enhanced available nitrogen (182.49 kg/ha), phosphorus (24.14 kg/ha) and potassium (323.23 kg/ha) recorded in soil after harvest of wheat over 50% of RDF in combination with nano fertilizers and control, on pooled basis. The microbial population of bacteria (55.55 × 107 CFU/g of soil) and fungi (29.07 × 104 CFU/g of soil) recorded at post-harvest stage were the highest with application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS which was on par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Economic analysis predict, that application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS gave maximum grain yield (4,399 kg/ha), net return (₹ 79,814/ha) and B: C ratio (2.94). Thus, based on the data of two years, it can be concluded that wheat grown under the agro-climatic condition of Zone-Ia, can be fertilized with 100% RDF (90 kg N/ha, 40 kg P2O5 and 20 kg K2O/ha) along with seed treatment with nano P @ 5 ml/kg of seed and two foliar spray of nano N @ 4 ml/L of water at 35 & 55 DAS for higher production and net return from wheat.
