Effect of phosphorus on growth and yield of summer mungbean (Vigna radiata L.) varieties sown after wheat
Abstract
An investigation entitled, “Effect of phosphorus on growth and yield of summer mungbean
(Vigna radiata L.) varieties sown after wheat” was conducted at Research Farm of Krishi Vigyan
Kendra, Ambala during summer season of 2014. The experiment was laid out in randomized block
design with four replications. The treatments comprised of two varieties (MH 421 and SML 668) and
four phosphorus levels (Control, 20, 40 and 60 kg P2O5 ha-1).
Mungbean variety SML 668 registered more plant height, higher dry matter accumulation
except at harvest, higher dry matter partitioning except in pods and more leaf area index than MH
421during all the stages of crop growth. Mungbean variety MH 421 produced more yield attributes
(branches per plant, pods per plant and grains per pod) grain, stover and biological yield than SML 668.
MH 421 also recorded more nutrient uptake than SML 668. Bolder grains were obtained from
mungbean variety SML 668.
Application of 40 kg P2O5 ha-1 recorded more growth, yield attributes, yield and nutrient
uptake, which was at par with 60 kg P2O5 ha-1. Mungbean variety MH 421 resulted in more net return
and benefit cost ratio than SML 668. MH 421 performed better than SML 668 and responded up to 40
kg P2O5 ha-1.
