    LAND SUITABILITY ASSESSMENT FOR MAIZE IN KRISHNA DELTA REGION OF ANDHRA PRADESH USING REMOTE SENSING AND GIS
    (Acharya N.G. Ranga Agricultural University, 2016) SIVA JYOTHI, V; PRASUNA RANI, P
    The present investigation entitled “Land suitability assessment for maize in Krishna delta region of Andhra Pradesh using remote sensing and GIS” was carried out to characterize and classify the soils of Krishna delta and to assess the suitability for maize. The maps depicting the changes in cropping pattern were prepared using remote sensing data and GIS. Soil samples for characterization, classification of study area were collected from representative pedons selected using remote sensing data (LANDSAT-8) and ground truth information. The samples were analyzed for physico-chemical, physical and chemical properties using standard procedures and were classified following USDA soil taxonomy classification (Soil Survey Staff, 2014). Suitability and capability classification of the study area was carried out as outlined by FAO (1976) and Sehgal (2008), respectively. The soil map including suitability classes was prepared using ARC GIS. The yield gap analysis was done using AquaCrop model. The study on temporal changes in cropping pattern during 1996-97 to 2015-16 revealed considerable reduction in rice-pulse system with corresponding increase in rice-maize system. The study area was characterized by semi-arid monsoonic climate with distinct summer, winter and rainy seasons. The soils were developed from fluvial sediments and coastal sediments. The soils were deep to very deep, very dark grayish brown to very dark gray in colour, clay to sandy in texture and single grain to angular blocky in structure. The bulk density values of the soils were low at surface compared to subsurface layers. Pore space, water holding capacity, volume expansion and sticky point values varied according to clay content. The soils were near neutral to slightly alkaline in reaction, non-saline to slightly saline, low to high in organic carbon and low to medium in CaCO3. The CEC values were varied from 3.37 to 66.20 cmol (p+) kg-1 and the exchange complex was dominated by calcium followed by magnesium, sodium and potassium. The analytical data of nutrient status of Krishna delta indicated that the soils were low to medium in available nitrogen, low to high in available phosphrous and potassium and deficient to sufficient in available sulphur, sufficient in manganese however remaining micronutrients (Fe, Zn and Cu) were deficient to sufficient. Chemical composition of soils revealed silica and sesquioxides were the dominant fractions followed by calcium and magnesium oxides. The coarse textured pedons registered high silica content revealed that siliceous nature. Based on morphological, physical, physico-chemical properties of the soils and climate of the region the maize growing soils of Krishna delta region were classified as: Pedon 1 : Fine, smectitic, isohyperthermic, Typic Haplustepts. Pedons 5 and 10 : Fine, smectitic, isohyperthermic (calcareous), Typic Haplustepts. Pedon 2 : Very-fine, smectitic, isohyperthermic, Udic Haplusterts. Pedons 3 and 6 : Fine, smectitic, isohyperthermic, Typic Haplusterts. Pedons 7 and 14 : Fine, smectitic, isohyperthermic (calcareous), Typic Haplusterts. Pedon 4 : Very-fine, smectitic, isohyperthermic, Typic Haplusterts. Pedon 13 : Very-fine, smectitic, isohyperthermic (calcareous), Typic Haplusterts. Pedon 8 : Fine, smectitic, isohyperthermic (calcareous), Vertic Haplustepts. Pedon 9 : Loamy, smectitic, isohyperthermic, Udic Ustorthents. Pedon 11 : Siliceous, isohyperthermic, Typic Ustipsamments. Pedon 12 : Siliceous, isohyperthermic, Oxyaquic Ustipsamments. The soils represented by pedons 1, 2, 3, 4, 5, 7, 8, 10 and 14 are moderately suitable (S2) due to moderate limitations of wetness, soil physical characteristics, fertility, soil salinity and alkalinity while, pedons 6, 9 and 13 are marginally suitable (S3f) with severe limitations of soil fertility (f) while, pedons 11 and 12 exhibited severe limitations of wetness (w) to maize, soil physical characteristics (s) and soil fertility (f). Based on the soil properties, the maize growing soils of Krishna delta were classified into land capability classes and sub-classes viz., IIIswf (pedons 1, 4, 6, 7, 8, 9, 10 and 13), IIIws (pedons 2, 3, 5 and 14), IVf (pedon 11) and IVsf (pedon 12). Yield gap of 28 to 58 per cent of observed yield and 21 to 39 per cent of simulated yield with potential yield was observed in the study area. The yield gap between potential yield and simulated/observed maize yield was wide in biomass than kernel. The mean yield gap was found to be lowest in clay textured soils followed by loamy sand and sand.

    DYNAMICS OF SOIL CHARACTERISTICS AS INFLUENCED BY ORGANIC AND INORGANIC SOURCES OF NUTRIENTS IN RICE FALLOW MAIZE CROPPING SYSTEM
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) MOHANA RAO, PULI; Dr. P.R.K. PRASAD
    In order to arrive at a profitable and eco-friendly nutrient management, it is necessary to consider cropping sequence as a whole rather than an individual crop, as the need for different nutrients by a crop would vary depending upon the preceding crop and its nutrient management. With this background, a field experiment was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laidout in a randomized block design for rice in kharif season with four treatments and replicated five times. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. The experiment on rice - maize sequence as detailed above was repeated on a separate site but in the same block during kharif 2012 and rabi 2013, respectively. Popular cultivars of rice and maize, BPT – 5204 and 30 V 92, respectively, were used for the study. Data collected on growth parameters viz., plant height, dry matter accumulation, yield attributes, grain yield, straw yield and nutrient content of rice were significantly higher with the application of 100%NPK in combination with FYM @10t ha-1. However, it was on par with that of green manuringtogether with 100% NPK during both the years of the study. Data collected on succeeding maize on growth parameters, yield attributes, yield, and nutrient content and uptake were significantly influenced by the nutrient management imposed to preceding rice crop, irrespective of NPK levels given to succeeding maize in the sequence. Plant height, dry matter accumulation, cob length, number of kernels cob-1 and kernel weight cob-1, test weight, kernel yield, stover yield, nutrient content and uptake of maize recorded in all those plots, which received organics along with 100% NPK to preceding rice were more than those received fertilizer NPK alone. Irrespective of nutrient management in kharif rice, increased N PK application to maize (75% to 175%) increased the kernel yield significantly in both the years (6825kg ha-1 to 8949kg ha-1 and 6544kg ha-1 to 8367kg ha-1, respectively). The maximum kernel yield (9116kg ha-1) of maize during 2012 was recorded with the application of 175% NPK and the residual effect of green manuring along with 100% NPK imposed to preceding rice crop whereas it was recorded with the application of 175% NPK and the residual effect of FYM @ 10t ha-1 along with 100% NPK imposed to preceding rice crop during 2013. The data regarding influence of organics applied to preceding rice crop and NPK levels applied to maize on nutrient content and uptake at different growth stages during both the years of the study was increased significantly with increase in level of NPK application to maize up to 125% NPK (N3) whereas, the treatments N3, N4 and N5 were on par with each other regardless the organics applied to preceding rice crop during both the years of the study. Application of organics in combination with inorganic fertilizers to preceding rice crop, irrespective of NPK levels, resulted in significant increase in nutrient content and uptake of succeeding maize in rabi than the treatment that had not received organics during both the years of study. In general, the available nutrient status and soil fertility status after harvest of each cropping sequence was higher by following organics along with 100% NPK imposed to preceding rice crop than that of 100% NPK alone.
