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.

    EXPLORING RESILIENCE OF RAINFED COTTON TO WEATHER VARIABILITY THROUGH HIGH PLANT DENSITY AND FERTILIZER REGIME: FIELD AND SIMULATION STUDY
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2018-12-17) GANVIR, MAHIPAL MAROTI.; Karunakar, Dr. A.P.
    A field experiment entitled “Exploring resilience of rainfed cotton to weather variability through high plant density and fertilizer regime: Field and simulation study” was conducted during kharif season of 2013-14 and 2014-15 at the All India Coordinated Research Project for Dryland Agriculture (AICRPDA), Dr. PDKV, Akola. The experiment was laid out in split plot design with three replications keeping six combinations of two weather variability viz., monsoon sowing and late sowing , with three plant densities i.e. 60 x 15 cm (1,11,111 plants ha-1), 60 x 10 cm (1,66,666 plants ha-1) and 45 x 10 cm (2,22,222 plants ha-1) under main plot and three fertilizer regimes viz., 100% RDF (60:30:30), 150% (90:45:45) and 200% (120:60:60) NPK kg ha-1 under sub plot. Cotton crop under monsoon sowing exhibited better growth and development with better canopy radiation interception and yielded higher seed cotton encountering comparatively better rainfall and thermal regime across the growing period with prevalently high canopy temperature depression and accrual of higher thermal units with high photo-thermal use efficiency. Population density of 60 x 15 cm (1,11,111 plants ha-1) produced higher growth and yield attributes of individual plant compared to population density of 60 x 10 cm (1,66,666 pl/ha) and 45 x10 cm (2,22,222 plants ha-1). However, higher planting density of 45 x 10 cm (2,22,222 plants ha-1) produced maximum seed cotton yield per hectare as increased number of plants compensated for fewer yield attributes plant-1 and cumulatively yield output was higher.Application of higher fertilizer regime 120:60:60 NPK kg ha-1 exhibited increased growth and yield attributes and; produced higher seed cotton yield availing higher thermal units with high photo-thermal use efficiency. Late sowing, higher plant density and lower fertilizer regime prompted earliness in phenological events and total crop duration. Crop under monsoon sowing, higher plant density and higher fertilizer regime recorded higher uptake of N, P and K in cotton seed, stalk of cotton and total uptake. Fibre length and micronaire value was more with monsoon sowing and higher fertilizer regime. Monsoon sowing and normal plant density showed higher seed index.By and large, rainfall, minimum temperature and humidity positively influenced the seed cotton yield whereas higher day time (maximum) temperature and diurnal temperature showed negative impact on seed cotton yield.CROPGRO-Cotton model simulation performance in respect of phenological phases was found to be reliable. The model predicted the seed yield reliably under weather variability and fertilizer regimes; however, performance of simulation of seed cotton yield was closely predicted in normal population density (100%) and with a greater degree of variability (underestimation) across higher population density (150% and 200%) . Both monsoon and late sowing recorded maximum seed cotton yield under high planting density of 45 X 10 cm (2,22,222 plants ha-1) with fertilizer regime of 120:60:60 NPK kg ha-1 followed by plant density of 45 X 10 cm (2,22,222 plants ha-1) with fertilizer regimes of 90:45:45 NPK kg ha-1. Pooled net monetary returns was statistically equal with the application of fertilizer 120:60:60 NPK kg ha-1 and 90:45:45 NPK kg ha-1 with similar benefit:cost ratio.
