    EFFECT OF NANOSCALE ZINC OXIDE PARTICLES ON THE YIELD AND YIELD ATTRIBUTES OF MAIZE
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) VENKATA SUBBAIAH, L; PRASAD, T. N. V. K. V.
    Revealing biological effects of nanoscale materials, especially in plants, is an important research area in bio-nanotechnology. Evaluation of the effects of nanoscale materials on agricultural crops is currently under exploitation. The present investigation was initiated considering the micronutrient deficiencies in the food crops especially the zinc. From the human health point of view, the enrichment of cereal grains with zinc is a desired outcome and in recent days there is an increasing interest in making the cereal grains with optimum zinc concentration. In the present study maize was selected as a test crop. Nano ZnO particles were prepared using modified oxalate decomposition method. As prepared ZnO nanoparticles were characterized using the techniques viz., UV-Vis spectrophotometer, Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and zeta potential analyzer. The mean size of the particles was found to be 25nm. A series of concentrations (50,100,200,400,600,800,1000,1500,2000ppm) of nano ZnO particles were examined to know the effect of nano zinc oxide particles on the germination, growth and development, yield and yield attributes of maize along with the bulk ZnSO4 and control. The highest germination percentage (80%) and seedling vigor index (1923.20) were observed at the 1500 ppm of nano ZnO particles whereas at the field level the physiological parameters such as plant height, leaf area, number of leaves and dry weight were significantly influenced by 400 ppm of nano ZnO particles. The yield (42% more when compared to the control and 15% higher compared to the ZnSO4 @ 2000 ppm) and yield attributes like cob length, number of rows cob-1, number of grains row-1 and test weight of maize grains were also highly influenced by the foliar application of nano ZnO particles (400 ppm). ICP-MS (Inductively coupled plasma – mass spectrophotometer) analysis revealed the higher accumulation of zinc in the grains (35.96 mg kg-1; 37% and 29% higher than control and bulk ZnSO4 @ 2000 ppm respectively) with the application of 100 ppm followed by 400 ppm (31.05 mg kg-1) of nano ZnO particles due to the net remobilization of zinc from the leaves to the grains during grain filling period; whereas at higher concentrations the zinc accumulation in the grains was low because of membrane saturation with Zn at higher concentrations. These results indicate that the nano ZnO particles have significant effects on the growth, development, yield enhancement of agricultural crops, maize in particular, and also enhances the zinc content of grains which is an utmost important feature in terms of human health perspective.

    GENESIS, CLASSIFICATION AND EVALUATION OF SOILS IN CHENNUR MANDAL OF KADAPA DISTRICT, ANDHRA PRADESH
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) SREEDHAR REDDY, K; NAIDU, M.V.S.
    The present investigation involves study of genesis, classification and evaluation of soils in Chennur mandal of Kadapa district, Andhra Pradesh. For this, eight representative pedons were selected in eight different locations of the study area covering all types of soils. All the eight pedons were described for their morphological features in the field and horizonwise samples were collected and analyzed in the laboratory for physical, physico-chemical and chemical properties. The study area was characterized by semi-arid monsoonic climate with distinct summer, winter and rainy seasons. The pedons selected were located on plains, very gently sloping and gently sloping topography. Pedon 1was developed from limestone whereas remaining pedons were developed from weathered gneiss. The morphological features indicated the presence of AC or AR (Pedons 1, 2 and 6) and ABC (Pedons 3, 4, 5, 7 and 8) profiles. The soils were shallow to very deep in depth, very dark grayish brown to dark brown in colour, sandy clay loam to clay in texture and had sub-angular blocky, angular blocky and crumb structure. The clay content decreased with depth in pedons1and 7. Pedons 3, 4, 6 and 7 showed no specific trend with depth. Physical constants like water holding capacity, loss on ignition and xv volume expansion followed the trend of clay content. All pedons exhibited an irregular trend of bulk density with depth, corresponding to decreasing organic carbon content with depth. The pedons were slightly alkaline to alkaline in reaction, non-saline and low to medium in organic carbon. All the pedons registered medium to high CaCO3 status. CEC values were low to medium and exchange complex was dominated by Ca+2 followed by Mg+2, Na+ and K+. Chemical composition of soils revealed that all the pedons had high silica content indicating siliceous nature. Regarding nutrient status, the soils were low to medium in available nitrogen, medium to high in available phosphorus, low to high in available potassium and high in available sulphur. However, soils were deficient in available iron and sufficient in available zinc (except in pedon 4 and subsurface horizons of pedon 3), copper and manganese. Based on morphological, physical, physico-chemical, mineralogical and meteorological data, the soils of Chennur mandal were classified as: Pedon 1: Fine, siliceous, isohyperthermic Lithic Ustorthent Pedon 2: Fine-loamy, siliceous, isohyperthermic Typic Ustorthent Pedon 3: Fine-loamy,smectitic, isohyperthermic Typic Haplustept Pedon 4: Fine,smectitic, isohyperthermicVertic Haplustept Pedon 5: Fine-loamy, smectitic, isohyperthermic Typic Haplustept Pedon 6: Fine-loamy,siliceous,isohyperthermic Typic Ustifluvent Pedon 7: Fine,smectitic,isohyperthermic Typic Haplustept Pedon 8: Fine,smectitic, isohyperthermic Vertic Haplustept Based on the soil properties, the soils of the Chennur mandal have been classified into land capability classes and sub-classes viz., IIw (Pedon 5), IIs (Pedon 8), IIIs (Pedon 1), IIIse (Pedons 2, 4 and 6), IIIwe (Pedon 3), IVew (Pedons 7). The soil-site suitability evaluation of study area revealed that pedons1, 2 and 6 were marginally suitable (S3) for rice and temporarily not suitable (N1) for groundnut and bajra, pedons 3 and 7 were marginally suitable (S3) for rice and bajra and temporarily not suitable (N1) for groundnut, pedons 4 and 8 were marginally suitable (S3) for rice, groundnut andbajra, pedon 5 was temporarily not suitable (N1) for rice, groundnut and bajra and pedon 6 was marginally suitable (S3) for rice and temporarily not suitable (N1) for groundnut and bajra.

    EFFECT OF NITROGEN AND POTASSIUM ON YIELD AND QUALITY OF PEARL MILLET
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) BHANU PRASAD REDDY, S; NAGA MADHURI, K.V.
    An experiment was conducted on sandy loam soils of S.V. Agricultural College Farm, Tirupati (A.P.) during kharif, 2013 in a randomized block design with eight treatments (nutrient management practices) viz., Control (no fertilizers) (T1), 60 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1 (RDF) (T2), 80 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1 (T3), 100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1 (T4), 60 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1 (T5), 80 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1 (T6), 100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1 (T7) and Application of N, P2O5 and K2O based on Soil Test Values (78 kg N ha-1 + 21 kg P2O5 ha-1 + 14 kg K2O ha-1) (T8). These treatments were replicated thrice. The pearl millet hybrid PHB-3 was tested with an inter and intra row spacing of 45 cm x 15 cm to find out its nutrient requirement. The recommended dose of fertilizer (100 % RDF) was 60 N + 30 P2O5 + 20 K2O kg ha-1. The entire quantity of P and K and half of N were applied at the time of planting while the remaining half of N was applied at 30 Days after transplanting (DAT). Nutrient management practices significantly influenced the growth characters (plant height and dry matter production at different stages of crop growth), yield (grain and straw), grain quality parameters (total protein, total amino acid and total carbohydrate content), nutrient content and uptake (N, P and K) by straw and grain at different stages of crop growth and soil fertility status after harvest. The growth parameters viz., plant height was maximum with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1) and dry matter production, was maximum with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1).While lowest values were observed with T1 (control) for plant height and dry matter production. Significantly highest grain and straw yields were obtained with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) which was on par with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1). The lowest grain and straw yields were obtained with control (T1). The maximum value of harvest index was noticed with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1), while minimum was observed with T1 (control). In case of grain quality parameters, the highest contents of total protein, total amino acid and total carbohydrate were recorded with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) which was followed by T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1). The lowest content was obtained with T1 (control). With respect to the content and uptake of nutrients by the crop, the highest content and uptake of N, P and K were recorded with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1). The least content and uptake of N, P and K was recorded with T1 (control). In grain, the highest nitrogen, phosphorus and potassium content and uptake was recorded with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) and the least was recorded with T1 (control). After harvest, at 0-15 cm soil depth, maximum values of available N was noticed with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) and highest available P was observed with T5 (60 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) while the highest available K content was with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1). Whereas at 15-30 cm soil depth, maximum values of available N and P were noticed with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1) while the highest available K content was with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1). The highest B : C ratio was recorded with T4 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1) which was on par with T7 (100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1). The lowest B : C ratio was noticed with T1 (control). Based on the above results, it may be concluded that for higher production with good grain quality, pearl millet crop has to be supplied with 100 kg N ha-1 + 30 kg P2O5 ha-1 + 40 kg K2O ha-1. However, for optimum and economic production, application of 100 kg N ha-1 + 30 kg P2O5 ha-1 + 20 kg K2O ha-1 can be recommended. Based on results, application of fertilizers based on Soil Test Values also resulted good yields with compared B : C ratio but lower than T4 and T7. This shows that the present RDF has to be changed for optimizing the yields.
