Yield and yield attributes of Mungbean (Vigna radiata L.) cultivars as affected by phosphorous levels under different tillage systems

Abstract

Two mungbean cultivars, Swat-1 and NM-98, four levels of phosphorous (0, 20, 40, and 60 kg ha−1) in the form of TSP, and four tillage systems, zero tillage (no tillage), minimum tillage (2-time), conventional tillage (4-time), and maximum tillage (6-time) were used. Results divulge that plant height, number of pods plant−1, number of seeds pod−1, biological yield, seed yield, 1,000 seed weight, harvest index, and protein content were significantly affected by mungbean cultivars, various phosphorous levels, and tillage systems. Cultivar swat-1 stands first in term of growth and yield. Highest thousand seed weight, seed yield, biological yield, and harvest index % were produced by P at the rate of 60 kg ha−1, while maximum plant height, number of pods plant−1, number of seeds pod−1, and protein content were given by P at the rate of 40 kg ha−1 at par with P at the rate of 60 kg ha−1. Among different tillage systems, maximum number of pods plant−1, 1,000 seed weight, biological yield, seed yield, and protein content were observed in maximum tillage system. In case of interaction between P × T, maximum pods plant−1, 1,000 seed weight, biological yield, seed yield, and protein content were produced by 60 kg P ha−1+ maximum tillage system.
