EFFECTS OF BIOFERTILIZER AND MACRONUTRIENTS ON THE YIELD AND YIELD COMPONENTS OF FENUGREEK SEED

Abstract

The experiment was conducted at “Central Research Farm” of Sher-e-Bangla Agricultural University, Dhaka, during November 2021 to April 2022 to study the effects of biofertilizer and macronutrients on the yield and yield components of fenugreek seed. The experimental material for the study was BARI Methi-1. The experiment consisted of single factor with total 13 number of treatments, T 0 = Biofertilizer 3 kg ha -1 , T 1 = Biofertilizer 3 kg+ 100 kg N ha ii

-1 , T 2 = Biofertilizer 3 kg + 40 kg P ha -1 , T 3 = Biofertilizer 3 kg + 60 kg K ha -1 , T 4 = Biofertilizer 3 kg + 75 kg N ha -1 , T 5 = Biofertilizer 3 kg + 30 kg P ha -1 , T 6 = Biofertilizer 3 kg + 45 kg K ha = Biofertilizer 3 kg + 50 kg N ha -1 , T 8 = Biofertilizer 3 kg + 20 kg P ha -1 , T 9 = Biofertilizer 3 kg + 30 kg K ha -1 , T 10 = Biofertilizer 3 kg + 100 kg N + 40 kg P + 60 kg K ha

= Biofertilizer 3 kg + 75 kg N + 30 kg P + 45 kg K ha -1 , T 12 = Biofertilizer 3 kg + 50 kg N + 20 kg P+ 30 kg K ha -1 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on yield and yield component of fenugreek seed and significant variation was observed for most of the studied characters, T 10 = Biofertilizer 3 kg+ 100 kg N+ 40 kg P+ 60 kg K ha treatment showed the best in seed yield. Under this investigation it was revealed that the maximum plant height (54.24 cm), number of primary branches plant -1 (7.68), number of secondary branches plant -1 (5.21), minimum days required to first flowering (36.89 days), days required to 50% flowering (57.02 days), longest pod length (12.16 cm), maximum number of seed pod -1 (15.22), weight of seed pod -1 (147.11 mg), seed weight plant -1 (12.33 g), weight of 1000 seed (13.58 g), seed weight plot -1 (429.67 g), seed weight ha -1 (1790.30 kg), highest harvest index (41.68 %), vigor index (590.33) and benefit cost ratio (3.51) was obtained from T 10 treatment . It was therefore concluded that that treatment T 10 = Biofertilizer 3 kg + 100 kg N + 40 kg P + 60 kg K ha performed positively to provide better yield and yield component of fenugreek seed.
