Effect of plant spacing and integrated nutrient management on the yield performance of Binadhan-14

Abstract

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from June to December 2014 with a view to finding out the effect of plant spacing and integrated nutrient management on the yield of Binadhan-14. The experiment consisted of three spacing viz., 25 cm × 15 cm, 20 cm × 20 cm and 20 cm × 15 cm and seven nutrient management viz., recommended dose of inorganic fertilizer @ 180-150-70-65-8 kg ha^-1 of Urea-TSP-MoP-Gypsum-ZnSO₄ respectively, cowdung @ 10 t ha^-1, poultry manure @ 5 t ha^-1,  50% recommended dose of inorganic fertilizer + cowdung @ 5 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha^-1, 50% recommended dose of inorganic fertilizer + cowdung @ 10 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. Crop characters, yield components and yield of Binadhan-14 were significantly influenced by spacing, integrated nutrient management and their interaction. The highest number of effective tillers hill^-1(6.81), 1000-grain weight (22.67 g) and grain yield (4.78 t ha^-1) were recorded at the spacing 20 cm × 15 cm while in case of integrated nutrient management, the highest number of grains panicle^-1 (64.47) was found with 50% recommended dose of inorganic fertilizer + cowdung @5 t ha^-1, on the other hand, 1000- grain weight (22.91g), and grain yield (5.02 t ha^-1) were found with 50% recommended dose of inorganic fertilizer +  poultry manure @ 5 t ha^-1 while the lowest values  from  poultry manure @ 5 t ha^-1. The highest grain (5.53 t ha^-1) and straw (6.23 t ha^-1) yields were found at the interaction of 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. It can be concluded that short duration Binadhan-14 can be transplanted at the 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @5 t ha^-1 to obtain maximum grain yield.
