Abstract:
The present investigation was aimed that, “Effect of nutrient sprays and plant growth regulator on growth, yield attributes and yield of chickpea (Cicer arietinum L.)” was conducted during Rabi 2020-21 at Experimental Farm (Block-B), Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The soil of experimental plot was clayey in texture and it is low in available nitrogen, medium in phosphorus and organic carbon, rich in available potassium and slightly alkaline in reaction. The experiment was laid out in randomized block design with eight treatments and three replications. Treatments consisted of foliar application of nutrient sprays xiii viz., T₁ - (Control), T₂ - (2% Urea spray at flower initiation and pod development), T₃ - (2% DAP spray at flower initiation and pod development), T₄ - (1% Urea + 1% DAP spray at flower initiation and pod development), T₅ - (2% KNO₃ spray at flower initiation and pod development), T₆ - (Organic plant extract @ 1% spray at flower initiation and pod development), T₇ - (Seaweed extract @ 0.2% spray at flower initiation and pod development), T₈ - (Grade II foliar spray of nutrient @ 2% at flower initiation and pod development). The gross and net plot size were 5.4 m x 4.5 m and 4.5 m x 4.2 m respectively. Among all the treatments Grade II foliar spray nutrient @ 2% (T₈) were significantly recorded the highest growth attributes, yield attributes, yield and economics of chickpea. Organic plant extract @ 1% (T₆) and 2% KNO₃ (T₅) which are at par with Grade II foliar spray nutrient at flower initiation and pod development stage.
