Field experiment reveals higher chickpea yield and soil fertility under reduced tillage with residue mulch in vertisols, suggesting sustainable productivity in rainfed systems.
A field study entitled, impact of conservation tillage on soil fertility, yield and nutrient uptake by chickpea in soybean–chickpea sequence on vertisols was conducted at the research farm of Dryland Agriculture unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, during Rabi 2021–22. The Vertisol of the study area was moderately alkaline in reaction, low in available nitrogen, medium in available phosphorus and high in available potassium. A randomized block design with four replications and five treatments consisted of conventional tillage with crop residue mulch and without crop residue mulch, reduced tillage with crop residue mulch, zero tillage with crop residue mulch, permanent BBF with crop residue mulch. The results indicated the improvement in soil fertility, higher nutrient uptake and yield of chickpea grown in Vertisols under rainfed conditions with reduced tillage and broad bed furrow in conjunction with crop residue mulch and application of pre-emergence herbicide.
