09. Impact of tillage systems on growth and yield of Mungbean (Vigna radiata L., Wilczek) varieties under dryland condition
Main Article Content
Abstract
The objective of this experiment was to study the impact of different tillage systems (zero, conventional, maximum and minimum) on growth and yield performance of four mungbean varieties (NM-92, NM-93, NF9M12-12 and Local) under dryland condition. The experiment was laid out in randomized complete block design with split plot arrangement having four replications. Tillage systems were allotted to the main plots and varieties to subplots. The results revealed that higher emergence m-2 (19 seedling m-2), delayed emergence (6 days), higher number of branches (5 branches plant-1) and number of pods plant-1 (20), taller plants (54 cm), heavier 1000-grains (26.08 g) and highest grain yield (384 kg ha-1) was recorded for variety NM-92. Increase in number of tillage had resulted in significantly higher number of seedlings m-2 (24), early emergence (6 days), minimum number of branches plant-1 (4), taller plants (66 cm), higher number of pods plant-1` (23), higher biological (2023 kg ha-1) and grain yield (402 kg ha-1). It was concluded from this study that growing mung variety “NM-92” under maximum tillage system showed promising results in terms of higher yield and yield components under dryland condition.
