Influence of Silicon Fertilization on Nitrogen Fractions and Nutrient Status of Rice Grown Soils in Telangana State
Excessive N application may limit the crop yields, and it could be minimized by the use of Silicon in rice ecosystem. Initially, a survey was conducted and revealed that rice grown soils were low in available Si (73.62 to 96.41 kg SiO2 ha-1 ) ). As well as Si concentration of rice genotypes ranged from 1.54 to 3.15% and grain yield ranged from 2653 to 6860 kg ha-1 and exerted a significant positive correlation (r = 0.55**). Based on initial phase of results, a field experiment was conducted A field experiment was conducted with each four levels of N (0, 80, 120 & 160 kg ha-1) and Si (0, 200, 400 & 600 kg ha-1). Among the N and Si doses, application of T16(N160 + Si600) recorded highest grain yield (7180 kg ha-1 ) and was on par with the treatments received N@120 and 160 kg ha-1 along with Si@200, 400 and 600 kg ha -1. . The status of available nutrients viz., N, P2O5, K2O, SiO2, Zn, Cu, and N-fractions were . The status of available nutrients viz., N, P2O5, K2O, SiO2, Zn, Cu, and N-fractions were . The status of available nutrients viz., N, P2O5, K2O, SiO2, Zn, Cu, and N-fractions were obtained high with T16 (N160 + Si600), which was at par with the treatments of T15 (N160 + Si400) > T14 (N160 + Si200) > T12 (N120 + Si600) > T11 (N120 + Si400) > T10 (N120 + Si200).
Influence of Silicon on Reduction of Methane Emissions for Sustainable Rice Production
The increasing human population requires greater rice production and methane is the second most potent greenhouse gas emitted from rice soils under anaerobic conditions. To address this, an experiment was carried out in two phases. In the first phase of the experiment, Si content accessed in the rice index leaves and recorded the mean values of 2.50, 2.48, 2.51 and 2.43% at Jagtial, Warangal, Rajendranagar and Rudrur varietal display plots in Telangana. For the second phase of field experiment, one with high Si (JGL-3855) and another with low Si (RNR-2354) content genotypes were selected with each four levels of N (0, 80, 120 & 160 kg ha-1) and Si (0, 200, 400 & 600 kg ha-1) in strip plot design. Conjunctive application of N and Si to both genotypes, JGL-3855 recorded significantly higher grain and straw yield compared to RNR-2354, among the different combinations of Si and N, application 160 kg N + 600 kg Si ha-1 recorded significantly higher grain and straw yields (7180 and 9693 kg).The treatments which received higher
dose of Si@600 kg ha-1 in combination with N@ 80, 120 and 160 registered the lower emission of
methane@ 25.7, 24.6 and 24.3 mg m-2 hr-1 and there was a significant scaling down of pest and
disease incidence was noticed in treatments wherever increased Si doses (0, 200, 400 and 600 kg )were included
Influence of silicon and nitrogen fertility rates on rice (Oryza sativa L.) yield and uptake
Negative impacts of excessive nitrogenous fertilizers could be minimized by the use of silicon. In order to study the effects of silicon and nitrogen on rice yield and uptake, a field experiment was conducted in two phases. Initially Si concentration in rice index leaves and available silicon status accessed and found low status of available silicon (73.62 to 96.41 kg ha-1) content. As well as, the mean Si concentration in rice index leaves also low, ranged from 1.54 to 3.15 per cent with an overall mean of 2.48 per cent. The grain yields ranged from 2653 to 6860 kg ha-1 with a mean of 5624 kg ha-1 and both were exerted a significant positive correlation (r = 0.55**). Based on these results, second phase of field experiment was conducted with sixteen combinations of Si and N with high Si (JGL-3855) and low Si (RNR-2354) content genotypes in strip plot design. Conjunctive application of N and Si to both genotypes, JGL-3855 recorded significantly higher grain and straw yields, nutrient content and total uptake compared to RNR2354. Among the different combinations of Si and N, application of 160 kg N + 600 kg Si ha-1 recorded significantly higher grain and straw yields, nutrient concentration and total uptake over control N0 + Si0 and was on par with N160 + Si400, N160 + Si 200, N120 + Si600, N120 + Si400 and N120 + Si 200.
Land suitability evaluation for crops in Warangal district of Telangana under Narsampet division
Six typical Pedon’s from central and eastern parts of Warangal district , Telangana were evaluated for their suitability to major crops Viz, rice, maize, cotton, chilly and red gram. The suitability classes ranged from highly suitable to permanently not suitable to these crops. Pedon’s 1,2,3,4,5,6 were highly suitable for cotton, rice, maize, chilly and red gram. Pedon 1,2,3,6 where Pedon’s 4,5 were moderately suitable for chilly, maize red gram and marginally suitable for Pedon 1,5,6 for different growing five crops.All the Pedon’s were not involved in temporarily not suitable and permanently not suitable any crop.Pedon 1 was also classified as marginally suitable for red gram and moderately suitable for rice, maize, chilly and cotton. Highly suitable for cotton due to alkaline PH and higher ESP. Soils are deep to very deep wetness, O.C. PH and CaCo3 content were limitations in all the Pedon’s. Texture was limiting factor
Influence of silicon fertilization on the incidence of rice insect pests and diseases in Telangana
Most of the pest and disease control measures used by farmers affect the soil fertility and plant resistance, which together leads to high control costs and make the rice cultivation unfeasible. To address this, an experiment was carried out in two phases. In the first phase of the experiment, Si content is accessed in the rice index leaves by utilizing 133 varieties with a mean value of 2.50, 2.48, 2.51 and 2.43% at Jagtial, Warangal, Rajendranagar and Rudrur varietal rice display plots of Telangana. For the second phase of field experiment, one with high Si (JGL-3855) and another with low Si (RNR-2354) content genotypes were selected with sixteen treatmental combinations of Si and Nin strip plot design. Conjunctive application of N and Si to both genotypes, JGL-3855 recorded significantly higher grain and straw yields compared to RNR-2354, and among the different combinations of Si and N, application 160 kg N + 600 kg Si ha-1 recorded significantly higher grain and straw yields (7180 and 9693 kg ha-1) over control (5622 and 7197 kg ha-1). The incidence of pests and diseases was significantly higher with the application of increased N levels by 0, 80, 120 and160 kg ha-1alone when compared to the conjunctive use of N and Si. However, significant scaling down of menace was noticed in treatments wherever increased Si doses (0, 200, 400 and 600 kg ha-1) included.

Six typical Pedon from central and eastern part of Warangal district, Eturunagaram division in Telangana
State were evaluated for their suitability to major crops viz, rice, cotton, maize, redgram and chilli. In the
study area, 6 pedons samples were collected and characterized. Crop suitability classification was carried
our adopting FAO guidelines. The suitability classes ranged from highly suitable to permanently not
suitable to these crops. Pedon 1 was not suitable for rice, moderately suitable for maize and chilliess and
highly suitable for redgram. Pedon 2 was highly suitable for maize chillieds and redgram slightly suitable
for rice cultivation and moderately suitable for cotton cropping. Pedon 3 moderately suitable for
cultivationof the irrigated-dry crops maize, cotton, chilli and redgram and highly suitable for rice
cultivation due to drainage related constraints. Very severe soil limitations in pedon 4 made it unsuitable
to cultivation of arable crops except redgram, for wchih it was slightly suitable. Maize, chilli and
redgram cultivation was highly suitable for pedon 5 soils. Pedon 6 was moderaly sutiable for cultivation
of the irrigated dry crops and highly cuitable for cultivation of rice crop. Soil constraint analysis was
done and remedial measures were also suggested
