the effect of stages of pinching of apical bud and spraying with nutritious solution (premium) on seeds and oil yield of Fenugreek (Trigonella foenum- graecum L.) ( PREMIUM) (Trigonella foenum- graecum L.)

A field experiment was conducted in a silt clay loam during the winter season of 2016-2017 in Diyala province using a factorial experiment according to Randomized Complete Block Design (RCBD) to study the effect of stage of pinching of apical bud at (without pinching, 35, 50 days) after germination and spraying with three levels of nutrition solution (PREMIUM) (0 , 0.4, 0.8 g.L-1) on seeds and oil yield of fenugreek plants. There was a significant effect and a probability level of 0.05 for the interaction treatment (pinching after 50 days of germination and spraying with nutritious solution 0.8 g.L-1) in the seed yield, biological yield and oil yield was 2080 kg.h-1, 16.61 g.plant-1 and 158.49 kg.h-1, respectively. while the interaction treatment of (pinching after 50 days of germination and spraying with the nutritious solution 0.4 g.L-1) gave a significant increase in oil percentage of (7.75%).نفذت تجربة حقلية في تربة طينية غرينية اثناء الموسم الشتوي 2016-2017
