Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    Title: RESPONSE OF WHEAT TO SURFACE AND SUBSURFACE DRIP IRRIGATION SYSTEMS UNDER DIFFERENT LATERAL AND EMITTER SPACINGS
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-02-18) Authors: LOKHANDE, JAYA NARENDRA; Advisor: Deshmukh, Dr. M. M.
    Abstract: A field experiment was conducted in clay loam soil at Jain Irrigation Systems Ltd., Jalgaon during rabi seasons of 2016-17 and 2017-18. Experiment was consist of eighteen treatments with three replications. The experiment comprised of three factors; (i) Irrigation methods – Surface (S1) and subsurface (S2) drip irrigation, (ii) Lateral spacings - 60 cm (L1), 80 cm (L2) and 100 cm (L3), and (iii) Emitter spacings - 20 cm (E1), 30 cm (E2) and 40 cm (E3). In subsurface drip irrigation lateral was placed at 20 cm depth in soil. 100 days wheat variety AKAW-4210-6. (PDKV Sardar) was sown at 20 cm crop spacing. The experiment was framed in Split-split plot design. Control was check basin irrigation method in which irrigation’s were given at six critical growth stages of wheat crop. Total water requirement of wheat was found to be 404.5 mm (40.45 ha-cm) under surface and subsurface drip irrigation method; whereas it was found 603.4 mm (60.34 ha-cm) in check basin method of irrigation; which results in 32.96 per cent saving of water through drip irrigation methods. Soil moisture content in 0-45 cm depth of soil gradually decreases with increase of both lateral spacings and emitter spacings. The soil moisture content in subsurface drip irrigation for different lateral and emitter spacings was found maximum between 15-30 cm soil depths; whereas in surface drip irrigation it was found maximum up to 20 cm soil depth only. The soil moisture content under L1 (60 cm) with all three emitter spacing was found more uniform in comparison with L2 (80 cm) and L3 (100 cm). The study indicated that maximum plant growth, flag leaf area, number of effective tillers per square metre, number of grains per earhead, test weight, grain yield and straw yield were recorded in L1 and E1. However growth and yield parameters were found to be statistically at par in surface and subsurface drip irrigation methods. The combination of L1E1 recorded desirable growth and yield parameters as compared other treatment combinations. Similarly surface and subsurface drip irrigation methods recorded higher growth and yield parameter as compared to check basin irrigation method. L1 recorded significantly highest yield of wheat compared to L2 and L3. E1 recorded significantly highest yield of wheat as compared to E2 and E3. As regards the water use efficiency (WUE) in wheat crop, treatment combination S1L1E1 recorded higher irrigation WUE (1.58). Whereas check basin irrigation method exhibited lower irrigation WUE (0.52). Economic analysis revealed that, maximum gross monetary returns (GMR) (114242 Rs ha-1) and net monetary returns (NMR) (72662 Rs ha-1) were observed in the treatment S1L1E1. While, minimum GMR (53120 Rs ha-1) and NMR (23813 Rs ha-1) were recorded in the control treatment T19 i.e. check basin irrigation method. The highest benefit cost ratio of 2.75 was recorded by the treatment combination S1L1E1 and lowest benefit cost ratio (1.71) was recorded by the treatment combination S2L3E3.
