Effect of planting geometry on yield attributes and yield of Indian mustard, Brassica juncea L.

Abstract

The experiment was conducted in rabi 2017-18 at Research Farm, College of Agriculture, Tikamgarh, J.N.K.V.V. (M.P.). The experiment was laid out in split plot design allocating three varieties to main plots and five planting geometries to sub-plots and replicated thrice. Pusa bold, RH-749 and RGN-73 with five planting geometries viz., 30 x 10, 30 x 15, 45 x 10, 45 x 15 and 60 x 10 cm were taken. Among varieties, RGN-73 produced significantly higher number of siliquae (plant-1) followed by RH-749 and Pusa bold. RGN-73 resulted into significantly higher seed, stover, biological yield and Harvest index. Among different planting geometries, 45 cm x 15 cm produced significantly a greater number of siliquae (plant-1), number of seeds, higher 1000-seed weight and higher harvest index (g). However, planting geometry 30 cm x 10 cm produced significantly higher seed yield and biological yield. RGN-73 under plant geometry 45 x 15 cm led to significantly higher yield of mustard and can be recommended.
