The experiment consisted of two main plots treatment of farmyard manure and pressmud compost and five subplots treatment organic manure levels of 0, 5, 10, 15 and 20 MT ha-1 along with full recommended dose of fertilizer of tomato crops followed by full recommended dose of fertilizer in green gram, replicated thrice in a split plot design in the same plots after harvest of tomato crop. Results showed that the seed yield of green gram crop increased significantly on the use of 10 MT ha-1 of farmyard manure and pressmud compost and further increased non-significantly over the control. The percentage increase in seed yield was 40.3 and 47.6, respectively for farmyard manure and pressmud compost in the treatment 10 MT ha-1 along with recommended dose of fertilizer over the control. Soil samples were analyzed for all the soil parameters and were found to be statistically similar across all treatments after the green gram crop. Thus it may be concluded that residual benefits could be possible in a subsequent legume crop even after heavy feeder crop like tomato crop is grown.

Considering the importance of plant analysis in fruit crops, the present investigation was carried out in an established orchard (since, 1979) at ICAR Research Complex for Eastern Region, Ranchi Centre to study the nutrient concentration in leaves of Litchi orchard as well as interrelationship between available nutrients present in leaf with crop productivity for developing a sound fertilizer management programme. Collection of leaf samples from established orchard was done during the 2006-07; analysis of leaf samples for secondary nutrients (Ca, Mg and S) in plant (leaf) part was carried out. The concentration of secondary nutrients varied from 0.099 to 0.225, 0.050 to 0.114 and 0.070 to 0.076 percent for Ca, Mg and S, respectively. However, mean leaf nutrient concentration was 0.162, 0.082 and 0.073 percent for Ca, Mg and S, respectively. Highest concentration of Ca, Mg and S was observed for the 4 th pair of leaves. Significant negative relationship between yield and concentration were observed in 2 nd and 4 th pair of leaves.

AFSs can sequester carbon and amend the organic matter, thereby enhancing the crop productivity. Carbon sequestration depends on the type of AFSs, climate, cropping pattern, and management practices. The aim of this study was to evaluate different AFSs for their potential to sequester carbon and impact on soil organic matter (SOM) in the eastern sub-Himalayas, India. Hedge-, alder-, and guava-based AFSs were established along with control (without any tree), and the maize–mustard–potato cropping pattern was followed in each AFS. Soil samples were collected after the fifth crop cycle and further analyzed. The results showed that crop productivity was significantly higher in all the AFSs than control. On average, soil organic carbon (SOC) was found to be significantly higher by 62 and 64% in hedge-based AFSs as compared to guava-based AFSs and control, respectively, and at par with alder-b...

For overcoming these constraints crop residue management is one of the best alternatives because of its diverse and positive effect on soil health. Crop residues management improves organic carbon and N content in soil, affects soil pH through accumulation of CO2 and organic acids produced during their decomposition in the soil, reclamation and management of saline and alkaline soil, behave as a reservoir for plant nutrients, decreases the bulk density of soil and increases the porosity of the soil, provides energy for growth and activities of microbes. We know that sustainability of the most of the cropping system depends on soil quality and improving the level of soil organic matter through incorporation of crop residues and other organic sources leads to improve soil quality and nutrient cycling and which also simultaneously provide alternative means for biomass disposal. Subsurface placement of rice residue as well as time of residue incorporation had a large impact on decomposition of rice residue (Singh et al., 2004b). The carbon and nutrient held in various soil organic matter pools are subsequently decomposed and assimilated by soil biomass resulting in additional mineralization. Immobilization process occurs simultaneously with mineralization process and the rate at which nutrients are available for plant uptake depends on net balance between mineralization and immobilization. In a long term experiment on a loamy sand soil in Punjab Agricultural University, Ludhiana, incorporation of residues of both crop in rice-wheat rotation increased the total and available P and K content of soil over removal of residues (Beri et al., 1995). Grain yield of wheat increased when it is sown in rice residue (Sidhu et al., 2011) and when residue is incorporated into soil (Ramesh Chandra, 2011). Management of crop residues offers sustainable and ecologically sound alternatives for meeting the nutrients requirements of crops and improving crop productivity.

Severe waterlogged situation poses to negative impact on agricultural production and productivity. In this context, the present study was investigated to assess the flood-prone areas of different panchayats in Sabour block with the aid of modern tools of RS&GIS. Landsat ETM+ , IRS-LISS III and Carto DEM have been employed to delineate the vulnerable zones in flood-prone areas of Sabour block, and had a visible impact on Kharif and Rabi crops. NDVI and spectral enhancement techniques had also been advocated to characterize and trace out tress less ecology in Tal land (heavy textured) and Diara land (light-textured soils). The results revealed that, out of 100%, only 32% of the agricultural lands (Chandheri, Baijalpur, Khankitta and Parghari panchayat) were highly affected due to frequent subsequent flood. From physio-chemical properties of soils, soil pH value was ranged from 6.25 to 7.89 which justify the slightly acidic to neutral in reaction. While the EC value content is found to be less than 1 dSm −1 and enable to justify safe for agricultural operation. From fertility point of view, low oxidisable organic carbon and available nitrogen have been observed in flood-prone areas. Whereas, low to medium and medium to high available phosphate and available potassium content were observed in the studied area. The geostatical point of view, there was more coefficient of variation of observed (>20%) in all soil nutrient's except soil pH, i.e., all soil nutrients geographically well distributed in study areas. From ongoing discussion, we could emphatically conclude that judicious application of organic and inorganic fertilizer enables to maintain the soil health and soil quality, and adequate land use planning offers to promote suitable aquaculture in spite of fallow land situation after recession of flood.

The data of long term experiment revealed that maximum grain yield of 46.83 qha-1 in wheat was obtained when 100% RDF applied through mineral fertilizers after 50% N of RDF being substituted with FYM in rice. Grain yield of wheat declined under control and sub-optimal fertilizer inputs (50% or 75% recommended fertilizer NPK), whereas positive yield increment was observed under treatments receiving organic supplements. The analysis of soil samples showed that soil pH reduced from initial value of 7.40 to 7.22, organic carbon build-up from 0.46% to 0.76%, available N from 194.00 to 225.95 kgha-1 available P2O5 from 23.60 to 49.54 kgha-1 and available K2O from 155.00 to 189.95 kgha-1 However, available Sulphur and DTPA-Zn increased from...
