Abstract

In order to study the effect of DENSITY and time of UREA FOLIAR APPLICATION on yield and yield components of BLACK CUMIN (Nigella sativa L.) a field experiment was conducted at Research Station of Faculty of Agriculture, Azad University of Birjand in 1387 growing season. Three UREA FOLIAR APPLICATION times [I-control 2-at 8-10 leaves stage 3-at 10% flowering 4-100% flowering] and three plant densities (100, 200, 300 plant m-2) were compared in split plot based on complete randomized block design with three replications. Studied components were 1000 seed weight, biological yield, seed yield, HARVEST INDEX, number of capsules per plant, number of seeds per capsule. Results showed that UREA FOLIAR APPLICATION times had significant effects on seed number per capsule and HARVEST INDEX. DENSITY had significant effects on capsules number per plant, seed yield, biological yield and HARVEST INDEX. Between all densities 200 plant m-2 and urea application at 8-10 leaves stage had the highest seed yield (593/33 kg/ha) and 100 plant m-2 and foliar application at 8-10 leaves stage had the lowest (243/33 kg/ha) seed yield. It seems that 300 plants m-2 and urea application at 100% flowering is the best treatment for BLACK CUMIN yield in birjand.
