Effect of planting geometry on growth and yield of mustard varieties

Field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, UP during Rabi season of 2011–12. The experiment was carried out in a randomized block design (RBD) with 12 treatment combinations comprising of three varieties NRC-HB 101, Rohini and Narendra Rye-8501 and four spacings 30 x 10, 45 x 10, 45 x 15 and 60 x 10 cm. All the treatment combinations were replicated three times. The maximum plant height was recorded in Narendra Rye-8501 that was significantly superior over Rohini and NRC-HB 101 with plant geometry 45 x 15 cm at 30, 60 and 90 days after sowing and at harvest stage of crop growth which was significantly higher over 30 x 10 cm, 45 x 10 cm and 60 x 10 cm plant spacing at all the stages of crop growth except at 30 DAS and other growth attributes viz primary branches, secondary branches and total branches/plant were also significantly superior in Narendra Rye-8501 under plant geometry of 45 x 15 cm at all growth stages. Number of seeds/siliqua was significantly increased in Narendra Rye-8501 under plant geometry 45 x 15 cm which led to significantly maximum seed yield of mustard superior to other treatments.
