Abstract:
A field experiment was conducted at Agronomy Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during rainy season of 2016-17, to study the effect of preparatory tillage systems on soil physical properties and soybean productivity. The experiment was laid out in randomized block design, assigning eight different tillage treatments and replicated thrice. Experimental results revealed that deep tillage treatment of PTtB (ploughing + 2 tyne harrow + blade harrow) recorded minimum value of penetration resistance and higher seed yield of soybean but remain statistically at par with another deep tillage treatment PTR (1 Ploughing + 1 Tyne Harrow + 1 Rotavator). Conversely the highest values of penetration resistance were recorded with treatment BR (Blade Harrow + 1Rotavator) and minimum lowest soybean productivity was recorded with treatment ZT (zero tillage).
