Effect of phosphorus fertilisation on growth, yield and quality of pea (Pisum sativum)

Abstract

In the present study, experiments were undertaken during 2016-2017 to examine the effect of phosphorus application on pea (Pisum sativum L.) cv. Arkel and Azad P-1. Four levels of phosphorus (0, 60, 90, 120 kg/ha) keeping the N at K dose constant at 25 and 50 kg ha-1 respectively with 3 replications were used in two way factorial analysis. The effects of different doses of phosphorus were judged on growth, yield and quality attributes. Evaluation of comparative performance of pea varieties Arkel and Azad P-1 in the climatic condition of Western plain zones of Uttar Pradesh suggested better performance of Azad P-1 over Arkel. However, on studying the interaction between NPK levels and Variety, Azad P-1 with P @ 120 kg ha-1 registered maximum pod yield (9.24 kg/plant) than Arkel (8.55 kg/plant). Results revealed that the performance of pea variety Azad P-1 was better than the variety Arkel. The higher number of pods per plant (17.94), weight of pods per plant (124.86 g), number of grains per pod (7.72) and pod yield per plot (7.79 kg) was recorded in the variety Arkel than Azad P-1. The study also revealed that ascorbic acid as well as total sugar content in harvested pods showed a declining trend with higher level of phosphorus irrespective of variety. Thus, pea variety Azad P-1 was found to be performing better with phosphorus application of 120 kg/ha in terms of growth, yield and quality attributes. This variety can hence be recommended for integration in horticulture based farming systems of Western Uttar Pradesh.

Productivity of Three Pea (Pisum sativum L.) Varieties as Influenced by Nutrient Supply and Meteorological Conditions in Boreal Environmental Zone

“…Pea varieties respond differently to fertilization [ 23 , 28 ] and environmental conditions [ 2 ]. The main traits that determine the level of adaptability in peas are a high harvest index, good ripening, disease resistance, resistance to shatter, high potential yield, seed weight, and seed number per pod [ 25 , 29 ].…”

Effect of Foliar Application of Gibberellic Acid on Plant Growth, Flowering and Yield Attributes in Pansy (Viola × wittrockiana Gams.)

“…Khangjarakpam et al [14], also observed similar results in marigold with application of GA 3 in China aster. Husain et al [15] also observed increase in seed yield with GA 3 application in pea.…”

Zinc Biofortification and Nutrient Management Effect on Growth, Yield and Yield Efficiency Index of Garden Pea under Himalayan Conditions

“…Ismail (2016) and Badr and Fayed (2020) reported, fertilization with a combination of N, P and K at different percentages has a positive impact on pod quality traits such as pod length, diameter, weight and seeds per pod. W here, phosphorus promotes reproductive growth, leading to higher pod yield, longer pods, more grains and more pods per plant Husain et al (2019) and potassium is crucial for plan t energy status, assimilate transloc ation and maintenance of tissue water relations. The results are in conformity with Akter et al (2020).…”
