Influence of different nutrient management on the growth and yield attributes of black gram

Abstract

A field experiment entitled “Effect of mycorrhiza, zinc and boron on growth and yield of blackgram” was carried out at Agronomy Unit, Dr. PDKV, Akola during kharif season of 2016-17 on clayey soil. The experiment was laid in randomized block design with nine treatments and three replications. Experimental results revealed that growth parameters were significantly influenced by application of (T6) i.e T2+ Mycorrhiza (AM) @ 10 kg ha-1 + Seed Soaking of 1% ZnSO4 followed by (T2) + Mycorrhiza (AM) @ 10 kg ha-1 + Seed Soaking 0.5% boron (T7). Similarly Yield attributing characteristics including grain and straw yield were significantly recorded higher values with the application of T2+ Mycorrhiza (AM) @ 10 kg ha-1 + Seed Soaking of 1% ZnSO4 (T6) followed by RDF + Seed Soaking of 1% ZnSO4 (T4). Straw yield and biological yield were significantly more in T2+ Mycorrhiza (AM) @ 10 kg ha-1 + Seed Soaking of 1% ZnSO4 (T6). The next best treatment was (T2) + Seed Soaking of 1% ZnSO4 (T4).
