Abstract

A field experiment was conducted in the sandy loam soil (Fluventic Haplustept) of Pandit Jawaharlal Nehru College of Agricult-ure and Research Institute, Karaikal, during Kharif 2015 to investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium. The experiment was laid out in Randomised Block Design with three replications. As such, the treatments consisted of three factors viz., sources, split and foliar applications. The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2). The results of field experiment revealed that the growth parameters like plant height, leaf area index, number of tillers, productive tillers, dry matter production and root biomass were significantly influenced by sources, split and foliar application of potassium. Similarly, the yield components viz., panicle length, panicle weight, test weight, number of grains per panicle, number of spikelets per panicle, spikelet fertility, high density grains per panicle were also found to be significantly influenced by the sources, splits and foliar application of potassium.


On the whole, this investigation had revealed that KClO3 could also be used as one of the sources of potassium for the growth and yield of aerobic rice. The application of potassium either through KCl or KClO3 in three equal splits at basal, panicle initiation and flowering stages along with foliar   application could be suggested as a strategy of potassium management for yield maximization in aerobic rice.
