Influence of Phosphorus Levels on Growth and Yield of Four Lentil Varieties

Abstract

An adequate supply of phosphorus (P) is important for the proper growth and yield of lentil, particularly in poor fertile soil. As such an experiment was carried out to evaluate the effects of phosphorus (P) fertilizer application on growth, yield, and yield components of lentil at the agronomy research field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during 2013-201. Four lentil varieties (BARI Masur-4, BARI Masur-5, BARI Masur-6, and BARI Masur-7) and four levels of P (0, 20, 40 and 60 kg P2O5 ha-1) were used in this experiment as treatment variables. Interaction of cultivar and P levels showed a significant influence on all the plant characters studied except plant height and branch production. The highest seed yield (1.98 t ha-1) was obtained from the combination of BARI Masur-7 with 40 kg P2O5 ha-1, and the lowest (1.08 t ha-1) was from BARI Masur-5 with 0 kg P2O5 ha-1. Addition of P fertilizer beyond 40 kg ha-1 decreased seed yield irrespective of varieties. Results revealed that the application of P fertilizer offers a large scope for obtaining a higher yield of lentil in Bangladesh. However, the application of P fertilizer at the rate of 40 kg P2O5 ha-1 would be the optimum for achieving higher yield irrespective of varieties.

Impact of Phosphorus Levels and Spacing on Growth, Yield and Development of Cowpea (Vigna unguiculata L. Walp.)

“…Significant and higher plant height was observed with application of phosphorus (50kg/ha) might be due to a sufficient quantity of phosphorus can stimulate biological activity. Similar findings have been reported by Sonet et al [11] in lentil. Further, higher plant height was observed with spacing (30cm×30cm) might be due to plant get sufficient space under wider spacing for light, air and nutrition for better growth and development.…”

Responses of Phosphorus and Zinc on Growth and Yield in Chickpea (Cicer arietinum L.)

“…The application of 90 kg P2O5 ha -1 resulted in the highest number of main and secondary branches, with values of 5.93 and 10.26, respectively while minimum values in control (3.61 and 6.40, respectively). Kumar et al [17], and Sonet et al [18] reported similar results. The data (Table -1) indicate that the number of primary and secondary branches per plant recorded at harvest increased significantly with zinc application in the crop.…”

“…The plant height exhibited a significant increase, rising from 46.19 cm under normal conditions to 53.71 cm when subjected to a dosage of 90 kg [17], and Sonet et al [18].…”

Assessment of Seed Quality Parameters of Mungbean Under Integrated Nutrient Management in Mollisols

“…Besides, phosphorus application stimulates crop growth along with dry matter production, leading to improved photosynthate translocation and sink development resulting in higher 100 seed weight (Karnavat et al, 2018). It also boosts nitrogenase activity of root nodules and prolongs crop maturity, having an impact on test weight in pulses (Sonet et al, 2020). Ram and Dixit (2001) and Hussen et al (2020) also observed higher test weight @ 60 kg P 2 O 5 ha -1 .…”
