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.

    RESIDUAL SOIL FERTILITY AND PRODUCTIVITY OF RAINFED ORGANIC COTTON IN VERTISOLS.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-07-07) SAPKAL, KALYANI ANIL.; Bhoyar, Dr. S. M.
    The present experimentation entitled "Residual soil fertility and productivity of rainfed organic cotton in Vertisols” was conducted to study the effect of continuous use of organic manures on physical and chemical properties of soil after harvest of rainfed organic cotton at Cotton Research Unit (CRU) Central Research Station, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola in kharif 2017-18. There were eight treatments replicated three times in Randomized Block Design. The organic sources used were FYM, vermicompost, sunhemp and castor cake. The soil sample were collected from surface and subsurface layers for analyzing various physical and chemical properties of soils. The soils of experimental site were classified under order Vertisol. Initially (2010-11) soils were low, medium and high in available nitrogen, phosphorus and potassium, respectively. After 7th cycle of fixed frame plot experimentation, continuous incorporation of FYM @ 10 t ha-1 showed significant improvement in soil physical and chemical properties as well as overall residual nutritional status of soil. Significantly lowest pH at surface and subsurface soils 7.81 and 7.91 and EC 0.11 and 0.12 dSm-1 were observed respectively. Same treatment 10 t ha-1 FYM showed significant improvement of organic carbon content of soils at surface (6.04 g kg-1) and subsurface (5.64 g kg-1) layers, as well as due to incorporation of higher dose of bulky organic manure 10 t ha-1 reflected on significantly superior improvement of available N (240.4 and 226.2 kg ha-1), available potassium (379.2 kg ha-1 and 331.3 kg ha-1) and available micronutrient of viz. Zn (1.28 and 1.24 mg kg-1), Cu (1.36 and 1.19 mg kg-1), Fe (15.71 and 15.20 mg kg-1), Mg (6.84 and 5.67 mg kg-1) in surface and subsurface soils, respectively. However, significant improvement of available phosphorus (34.31 kg ha-1 and 28.03 kg ha-1) at both soil layers observed in vermicompost @ 5 t ha-1 treatment. A regards of physical properties of surface and subsurface soils significant improvement in bulk density(1.23 and 1.27 Mg kg-1), hydraulic conductivity (1.29 and 1.24 cm hr-1), available water capacity (17.3 and 9.71%) and mean weight diameter (1.84 and 1.64 mm) was recorded due to bulk application of organic matter through FYM @ 10 t ha-1. Significantly, higher and statistically equal seed cotton yield harvested under the treatment FYM 10 t ha-1 (19.28 q ha-1) and concentrate organic manure 500 kg ha-1 (19.16 q ha-1) which led to higher PRI under both the treatments i.e.175.27 and 174.18 q ha-1 per cent due to their continuous use of seven years. Thus, after 7th cycle of the experimentation on organic cotton production, it can be concluded that, significant improvement of physical and chemical properties of Vertisols can be possible due to continuous use of organics as sources of nutrients to deshi cotton crop over the absolute control as well as initial status of soil. In general it was noticed that, surface soils showed more improvement as regards to all properties than the subsurface Vertisols. Furthermore, improvement of residual fertility status and was reflected on the productivity rating index of deshi cotton variety (AKA-8). However, as per the availability of bulky organic manure or concentrate organic manure either FYM @ 10 t ha-1 or castor cake @ 500 kg ha-1 can be used for obtaining optimum yield of deshi cotton in rainfed condition.
