Influence of irrigation regimes, row spacing and varieties on biomass partitioning in summer mungbean (Vigna radiata (L)) under middle gujarat agro-climatic zone

Field experiment was conducted at B. A. College of Agriculture, Anand Agricultural University, Anand during summer season for two consecutive years 2015 and 2016 to study the influence of irrigation regimes (I1: 0.8 IW: CPE ratio, I2: 0.6 IW: CPE ratio and I3:0.4 IW: CPE ratio) and row spacing (S1:45 cm and S2:30 cm) on biomass partition of two varieties (V1: Meha and V2: GM-4). Results revealed that periodical leaf weight, stem weight were recorded highest at all 10 days interval with irrigation scheduling at 0.8 IW: CPE (I1) ratio while lowest was recorded at 0.4 IW: CPE (I1) ratio. Variety Meha (V1) produced higher biomass as compared to GM-4 (V2) from 50 DAS till harvest of crop resulted in higher biomass accumulation and final yield. Row spacing 30 cm (S2) produced higher biomass viz., leaf dry weight, stem dry weight and root dry than 45 cm (S1) during both the year. Highest root weight was recorded with irrigation scheduling at 0.4 IW: CPE (I3) ratio while lowest recorded under treatment 0.8 IW: CPE (I1). | Influence of irrigation regimes, row spacing and varieties on biomass partitioning in summer mungbean (Vigna radiata (L)) under middle gujarat agro-climatic zone
