Abstract:
A field experiment was conducted during kharif season of 2020-21 at Mega Seed, Pulses and Castor Research Unit, Navsari Agricultural University, Navsari to study the effect of different herbicide on growth, yield and available N in pigeon pea growing soilunder large plot technique design. Pendimethalin 1000 g a.i./hashowed significantly higher plant height and number of plant branches at 60,90 DAS and seed yield and stalk yield at harvest whereas it was remained at par with treatment of pendimethalin 2000 g a.i./ha followed by all the treatment except control. The treatment i.e. application of pendimethalin 2000 g a.i./ha showed significantly highest available N in soil at 60, 90 DAA and at the time of harvest it was remained at par with treatment of pendimethalin 1000 g a.i./ha followed by control, Imazethapyr 150 g a.i./ha, Imazethapyr 75 g a.i./ha and oxyfluorfen 250 g a.i./ha respectively.
