ABSTRACT

A field experiment was conducted during kharif and rabi seasons of 2002-2003 and 2003-2004 on a saline soils, to study the effect of various levels, methods of application and residual effect of Zn on yield, nutrient concentration and uptake of blackgram ( Vigna mungo). Twelve treatments comprising of four ZnSO4 levels (0, 12.5, 25 and 50 kg ha-1) were distributed to the two crops of rice-blackgram in a cropping system. The maximum grain and haulm yields of blackgram were recorded with treatment that received 25 kg ZnSO4 ha-1 to blackgram. The effect of all foliar treatments applied at different stages of crop proved to be at par with each other. The performance of the treatments was in the order: soil application > foliar treatments > residual fertility. The nutrient status of soil at the end of rice-blackgram cropping sequence indicated that the available N and Zn status of soil increased and that of K to decrease when compared with the initial soil status.
