Effect of Integrated Application of Inorganic and Organic Sources on Soil Properties, Yield and Nutrient Uptake by Rice (Oryza sativaL.) in Intermediate Zone of Jammu and Kashmir

Effect of Urea Briquettes in Combination of Organics on Root Growth and Nitrogen Losses in Rice Field

“…The treatment T9 performed better due to slow and regular release of nitrogen as briquettes with organics provide better nutrient use efficiency and minimum nutrient losses so that plant can easily uptake nutrient in their critical growth period. Similar result was reported by Mishra et al, (1999), Laxminarayana (2006 and Sunitha et al, (2010) and Chesti et al, (2015). Overall findings indicate that, Urea+FYM briquette application among different sources of fertilizer nitrogen was found most suitable for irrigated ricein terms of better root growth and minimum nitrogen losses.…”

Effect of different phosphorus sources applied with phosphate solubilizing bacteria on bio-geochemical properties and phosphorus release pattern in vertisol

“…Present study results are in line with those ofMarschner et al,2003;Amitava et al, 2008;Chesti et al(2015),they opined that soil microbial community structure was affected by addition of organic amendments, composted water hyacinth material could serve as quality manure for improving soil health and manurial application attributes direct addition OC content to soil which stimulate growth and activity of microorganisms, respectively. Further,Zhao et al (2010) reported a close relationship between microorganism growth and activity to organic matter content in the soil.…”

Influence of Integrated Nutrient Management Strategies on Soil Fertility

“…The integrated nutrient management treatment 50% N through FYM + 50% NPK through fertilizers recorded the highest available P content in soil . Chesti et al, (2015) reported that incorporation of FYM along with 100% NPK recorded significantly higher available P as compared to all other treatments. The increased availability of available P with organics could be ascribed their solubilising effect on the native insoluble P fractions through release of various organic acid, thus resulting into a significant improvement in available P status of soil (Urkurkar et al, 2010).…”

“…There was a significant build up of available N in soil receiving 100% NPK along with FYM @ 10 t ha -1 over other treatment. This may be due to optimal fertilizers input (Chesti et al, 2015). Verma et al, (2012) reported that the balanced use of fertilizers alone or conjoint use of inorganics with organics resulted in a significant build up of available N over three decades leading to sustained soil fertility.…”

“…The status of available K declined in almost all the treatments except 100% NPK + FYM @ 10 t ha -1 as compared to initial status. The increase in available potassium under irrigated treatment might be due to addition of organic matter that reduce K fixation and released K due to interaction of organic matter with clay (Chesti et al, 2015). Singh et al, (2006) reported that available K status of soil increased with the application of organic manure viz., FYM, rice straw, dhaincha and chemical fertilizer individually or in combination by 180-660 kg ha -1 after rice and 25.1-78.4 kg ha -1 after wheat.…”
