Effect of Phosphorous and Potassium on Growth Parameters, Yield and Yield Attributes of Chickpea (Cicer arietinum L.) under the Rainfed Condition in Chitrakoot, India

Abstract

The present study investigate the effect of phosphorous and potassium on growth parameters, yield and yield attributes of chickpea (Cicer arietinum L.) under the rainfed condition in Chitrakoot, India. Field experiments were carried out to investigate the effect of phosphorus and potassium on chickpea growth parameters, yield components, and yield during the rabi season of 2021-22 at Rajoula Agriculture farm, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.). The experiment consist of nine treatments combinations in factorial randomized block design with three replications consisted of three levels of phosphorous (50, 60 and 70 kg ha-1) and three potassium levels (30, 40 and 50 kg ha-1). Chickpea variety IPC-2011-112 was grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the growth parameters maximum plant height at 90 DAS is 37.40 cm, maximum number of branches at 90 DAS is 32.53 and maximum number of nodules plant-1 at 45 DAS is 46.00 during the study were associated with the treatment T9 [70 kg P2O5 ha-1+ 50 kg K2O ha-1]. Similarly, among the yield components and productivity parameters maximum values in relation to number of pod plant-1 (69.33), number of seed pod-1 (1.73), 100 grain wt. (22.66 gm) and grain yield (16.85 q ha-1) was also found in the treatment T9 [70 kg P2O5 ha-1+ 50 kg K2O ha-1].

Effect of Seaweed Extract (Algareen-Twin) and Bio-Fertilizer (Optimus-Plus) on the Growth and Yield of Barley

“…These results are consistent with what was found by [32,33,34] The results of Table (6) showed that there was a significant difference among the levels of the Optimus-plus (bio-fertilizer) in terms of the number of spikes, as it reached (428.06 spikes.m -2 ) at the level of (150 ml.100 L of water -1 ), the reason for the increase in the number of spikes is that the amino acids present in the bio-fertilizer and the organic materials contributed to an increase in cell expansion, which ultimately led to an increase in the spikes number. This result is in line with what was reported by [35,36].…”

Integrated foliar application of potassium with soil applied nitrogen and phosphorus improves productivity of chickpea (Cicer arietinum L.)

“…Nitrogen, phosphorus and potassium are deficit in soil under chickpea cultivation in Punjab (Pakistan). The N, P and K are indispensable to improve growth, yield and yield attributes of chickpea (Rajput, 2018;Tembhare et al, 2022). Nitrogen is a crucial nutrient for plant growth and development, plays a key role in photosynthesis, phytohormonal regulation, proteomic changes, and overall, to complete plant lifecycle.…”

“…Potassium also plays a key role in nitrogen metabolism (Xu et a., 2020) and thus improves nitrogen use efficiency. co-application of phosphorus with nitrogen (Ivanov et al, 2021) and phosphorus with potassium is proved to offer higher yield than their individual use in chickpea (Ali et al, 2010;Tembhare et al, 2022). Expensive potassium fertilizers are the primary reason for avoiding potassium application in pulses.…”
