The experiment comprising of four levels of phosphorus, i.e., 0, 20, 40 and 60 kg ha−1 and four levels of zinc, i.e., 0, 5, 10 and 15 kg ha−1 was conducted to investigate the interaction effect of phosphorus and zinc fertilization on yield and yield attributes of green gram [Vigna radiata (L.) Wilczek] cv. SML-668. The treatments were laid out in randomized block design (factorial) with three replications. The results revealed that plant height, number of pods plant−1, 1000 seed weight, seed and stover yield were increased significantly up to 60 kg ha−1 phosphorus and 10 kg ha−1 zinc treatment levels. Further increase in zinc levels found to decrease the yield and yield attributing traits, indicating antagonistic effect of phosphorus and zinc on each other. The highest plant height, number of pods plant−1, 1000 seed weight, seed and stover yield (at 60 kg P ha−1 and 10 kg Zn ha−1 treatment level) were 48.70 cm, 27.15, 32.70 g, 957.25 and 2398.30 kg ha−1, respectively. Thus, interaction of phosphorus and zinc was significant for all the growth and yield attributing parameters.
