Effect of calcium silicate and need based nitrogen on pests management in aerobic rice (Oryza sativa L.)

Abstract

The dynamic and severity of pests attack has shifted with the adaptation and spread in rice. Excessive use of chemicals for pest and diseases control in agriculture is known to degrade the environment. Use of silicon (Si) and nitrogen (N) management in aerobic rice involves a proper choice and blend of compatible tactics to keep the pests at low level. The present investigations were done to know the effect of calcium silicate and nitrogen on the pest infestation in aerobic rice. The results revealed a significant decreases of pests i.e. Leaf folder (Cnophalocrosis medinalis), Brown plant hopper (Nilaparvata lugens), White backed plant hopper (Sogatella turcifera), Green leaf hopper (Nephotetticx virescens) with the application of calcium silicate at 2 t ha -1 and 90 kg N ha -1 (30 kg N ha -1 as basal+ LCC-3) and par with 60 kg N ha -1 (No basal + LCC-3). This study suggested the importance of Si and LCC based N application for achieving to keep the pests population and higher grain yield and straw yield.How to view point the article : Kumara, B.H., Yogendra, N.D., Prakash, N.B. and Kumar, Amarendra (2016).

Influence of Calcium Silicate on the Chemical Properties of Pleurotus ostreatus var. florida (Jacq.) P. Kumm

“…Silicon (Si) is the second most abundant element in the earth’s crust and its effect on organisms may be different, serving as a cellular chemical element or providing a natural morphological modification [ 7 , 8 , 9 , 10 , 11 ]. As a cellular chemical element, it plays an important role in the mineral nutrition of plants, aiding development by increasing the organism’s biomass.…”

“…On the other hand, calcium silicate is also used to provide a natural morphological modification in insects, that is, when ingested occurs damage to the oral apparatus of pests that attack plants, due to its crystalline physical structure [ 9 , 12 , 13 , 14 , 15 , 16 ]. Previous studies have reported reduced insect feeding on turf treated with calcium silicate, as well as others that show that calcium silicate enhances resistance of sugarcane to the African talk borer Eldana saccharina [ 13 , 17 ].…”

Antioxidant and Antimicrobial Influence on Oyster Mushrooms (Pleurotus ostreatus) from Substrate Supplementation of Calcium Silicate

“…They are used in the biomedical field, where they have shown great biocompatibility, antibacterial activity, and bioactivity; the latter plays a fundamental role in the regeneration and healing of tissues, and the performance of calcium silicate materials is largely attributable to their bioactivity [8][9][10]. It has also been widely used in the production and cultivation of different plant crops [11][12][13][14][15]. The high compatibility of calcium silicate and mushrooms when compared to other supplementation materials has attracted attention towards its supplementation in several crops.…”
