    Effect of Nitrogen Phosphorus Potassium and PGR on Growth Yield Quality and Processing of Cape -Gooseberry (Physalis Peruviana Linn)
    (Birsa Agricultural University, Ranchi, 1988) Keshow Kumar Jha; B.P. Jain
    Studies on the effect of four levels of nitrogen (60Kg, 80Kg, 100Kg and 120Kg/ha), three levels of phosphorus (50kg, 75kg, and 100 Kg/ha) and two levels of potassium (50 kg and 100Kg/ ha) and two levels of GA3 (20 and 40ppm) and ethrel (200and 300ppm) were made on growth, yield , quality and storage capability of cape gooseberry during 1991-1992 and 1992-1993 in the department of horticulture, Birsa Agriculture university kanke Ranchi. Higher dose of nitrogen (120Kg/ha) phosphorus (100 Kg/ ha) and potassium (100Kg/ ha) had shown promising effect on growth, yield and quality of cape- gooseberry. Jam can be stored upto 365 days at room temperature with very good taste in N3P3K2 treatment. In second experiment crop was grown with the recommended dose of N,P, K i.e 80:80:80 (singh et. al , 1977). Higher dose of GA3 (40ppm) gave 54.25q/ha and ehtrel (300 ppm ) gace 51.05q/ha whereas control gave only 48.50 q/ha. A yield of 74.18 q/ha was attained with the application of NPK @ 120, 100, and 100Kg/ ha in control with maximum cost : benefit ratio of 1:2.13.

    Some Aspect of Mastitis in Buffaloes
    (Birsa Agricultural University, Ranchi, 1987) Praveen kumar; Dr. A.K.Sinha
    Hazarduous effect of mastitis on the socio-economic status of the farmers through the loss of milk and health of the animals leading to their culling and sacrifice is well established. With a view to asses the incidence and prevalence of mastitis in buffaloes in and around Ranchi in different farms with respect of daily milk yield, month of lactation, parity, types of infection and quarterwise infection by different indirect tests, the present investigation work was undertaken. To study these aspects of mastitis in buffaloes one organised farm, three unorganised farms and several private owners comprising the mixed group in and around Ranchi were taken for this study. Out of 259 milch animals 112 buffaloes were examined for incidence and prevalence of mastitis by indirect tests viz.trypsin inhibitor test, modified California mastitis test and bromothymol blue indicator card test and clinical observations were carried out to detect clinical, subclinical and chronic mastitis in these animals. To find out the causative organisms of mastitis and for their cure; culture, isolation, identification, sensitivity to different drugs, biological test for confirmations and drug trials for their treatment with different drugs were carried out in 29 buffaloes who were found positive for mastitis. Comparison of indirect tests for its suitability in detecting mastitis and efficacy of treatment for selection of drugs and line of treatment were carried out to have a better result of the research,

    To Evaluate Relative Efficiency of Mussoorie Rock Phosphate and Purulia Rock Phosphate as Source of Phosphorus and Calcium and Their Effect on Various Physico-Chemical Properties of Soil
    (Birsa Agricultural University, Ranchi, 1985) Sagar Pasad Singh; K.P. Singh
    A field experiment was conducted at the research farm of Birsa Agricultural University, Ranchi in the year 1983 with application of Tata basic slag, Mussoorie Rock Phosphate, Purulia rock phosphate, Single super phosphate to compare their efficiency as a source of phosphorus and calcium on yield of soybean crop and various soil properties. The efficiency of utilization/added phosphorus by soybean crop depended on the source of phosphatic ferti lizer and their effect soil pH, available P content, exchangeable Ca content of soils, lime potential, phosphate potential, phosphate fixing capacity of soils, and P-trans formations in soils. The highest yield of grain and straw was obtained in case of single super phosphate followed by basic slag followed by Mussoorie Rock Phosphate followed by Purulia Rock Phosphate when applied at the rate of equal P₂05 content basis. The yield of soybean was significantly positively correlated with pl, available P, exchangeable Ca and line potential of soils and Fe-P and Al-P fractions of soils. The yield of soybean was significantly negatively correlated with Phosphate potential and phosphate fixing capacity of soils. The lime potential was significantly positively correlated with exchangeable Ca of soils. The pH of soils was significantly positively correlated with available P, exchangeable Ca and lime potential of soils and significantly negatively correlate with phosphate potential and P fixing capacity of soils.

    Cumulative Effect of Long-Term Manuring and Fertilization On yield And Some of The Properties of An Acid Paleustalf Soil Under Irrigated Condition In Multiple Cropping System
    (Birsa Agricultural University, Ranchi, 1989) Shailendra Kumar Singh; B.S.Mathur
    The present project was undertaken to assess the changes brought out by the cumulative effect of manure, lime, sulphur and fertilizers, after 15 years of continuous application, on status of major nutrients, different forms of aluminium, phosphate fixing capacity etc. in surface and subsurface layers. The important findings are summarised below : 1.The fine particles in the surface and subsurface soil increased without affecting the textural class clay loam. 2. Fertilized soils were more reddish than the control and the colour did not change due to continuous cropping. 3. Acidity increased in surface and subsurface soil in fertilized plots and it was more in ammonium sulphate than the urea treated soil on equal nitro gen basis. Acidity increased with time. Treatment N was more acidic than NP and NPK. 4. With the increase in soil acidity all forms of Al also increased from the initial value in both the layers. 5. P-fixing capacity of soils increased with increase in soil acidity. 6. Organic carbon level of surface soil increased by 15.5 per cent over the initial value after 6 years of continuous application of FYM but decreased after 10 years. Use of chemical fertilizer lowered its level ranging between 4.9 and 29.6 per cent Organic carbon content in the surface was not affected. soil 7. Available N, P and K increased in surface and subsurface soils with passing of time. 8. Normal dose of NPK was better than subnormal or super-normal doses. Urea proved better than ammonium sulphate in increasing the yield of crops. 9. NPK was better than N, NP or PK in increasing the yield of crops.

    Changes in Soil Properties under Different Toposequence And Land Use System
    (Birsa Agricultural University, Ranchi, 1983) Ashok Kumar Jaiswal; B.S.Mathur
    From the studies made in this project on soils, developed from the same parent material - Granite gneiss, under similar climatic conditions but differing in land situations and management practices, the following conclusions can be drawn in respect of the variations in their properties. A. Land situations (Upland vs Medium land): 1. Uplands have sandy loam texture under farmers practice while medium land have sandy loam to loam texture. 2. Bulk density and moisture retention at 15 bar and 1/3 bar at 15-30 cm depth are more on uplands. 3. Porosity and aggregation are less on uplands. 4. pH, w/s Al & C.E.C. are low on uplands. 5. Uplands under irrigated condition and medium land under unirrigated condition have more organic carbon. 6. Available P (Bray P₁ & P) is high but available K is less on uplands. 7. Exchangeable Ca + Mg is low but exchangeable H and exchangeable Al at pH 4.8 and 7.0 (under un irrigated condition) are high on uplands. B. Management practices (Improved cultural practice Vs farmers cultural practice): Improved cultural practices has an edge over farmers practices in the following ways: 1.More clay in surface soils on uplands while irrigated medium land soils have more clay in sub-surface soils. 2. Porosity and aggregation are high but bulk density is low. 3. 1/3 bar is less on uplands but more in medium land. Moisture retention in subsoil at 15 bar and 4. Organic carbon is high. 5. Available P (Bray P₁ & P₂) is low under irrigated and high in irrigated uplands while available.

    Urea Fertilizers And Their Management Practices For Lowland Rice
    (Birsa Agricultural University, Ranchi, 1982) Ganesh Prasad Saha; B. N. Mitra
    Based upon the finding of experiments summarized above, it may be concluded that there is considerable possibility in the improvement of grain yield and N content in grain of lowland rice by growing improved varieties with suitable from of urea and their appropriate N management practices .For a long duration variety like Pankaj ,application of LCU as single basasl or in two equal splits at an interval of 30 days can increase the yield considerable .For a short duration variety like Pusa 33, a high level of production can be expected even with OU if applied in two equal splits particularly the basal half by plough sole method. A medium duration variety like Ratan whose N requirement is moderate ,split application .In the soils of medium fertility , 54 KgN/ha is adequate to achieve high yields as well as recovery during wet season. The results further suggest that a high yield variety even of moderate N requirement if grown during dry season is necessarily to be supplied with higher level of N as compared to wet season. Under continuous flooded conditions –Common feature of lowland, application of LCU is more promising than other indigenous from of urea for increasing the yield as well as recovery of N. This also holds true for irrigated lowlands, where wet season rice is mostly followed by a dry season rice. Application of OU by broadcast –incorporation is to be avoid as far as possible and , insect, plough sole method may be adopted after 3-5 days of puddling or just before transplanting. For obtaining good response with USG placement in two equal splits at planting and at 30DAT is most appropriate and single basal placement in higher dose if necessarily to be avoided. Under limited supply of N, even with 27 Kg N/ha, high yield can be expected if aslow releases form like LCU is applied in place of other comparatively fast- releasing forms. In soils where leaching loss of N is considerably low, USG may prove to be as good as slow release forms like LCU. Both these forms, being indigenous, hold promise to the present day lowland rice cultivation where sustained efforts are being made extensively to improve the utilization of N from Urea.

    Studies on Maize Germplasm Complexes By Line X Tester Analysis
    (Birsa Agricultural University, Ranchi, 1986) Dilip Kumar Ganguli; D.P.Srivastava
    Present investigation was taken up to evaluate some newly developed germplasm complexes of maize for their future utilization in crop improvement programme. Eleven diverse germ plasm complexes used as females were crossed with three open pollinated heterozygous testers, of different genetic base, as males. Thirtythree cross combinations along with fourteen parents and one check variety were evaluated for two years for variability, heterosis and combining ability. The line x tester analysis for combining ability was done with crosses alone. Pooled analysis of variance components, combining ability variances and combining ability effects were done for twelve quantitative characters. Simple correlation and rank correlation was done to ascertain the association of parental performance and general combining ability effects and also for determining tester efficiency. The parents and crosses were found to differ significantly for almost all the characters in both the years. The mean values of the crosses were more than the parental mean of various characters. The phenotypic coefficient of variation was higher for grain yield, ear height, number of kernels/ear and 100-grain weight. Large number of crosses were found to give significant heterosis over mid-parent, better parent and over the check variety in majority of the characters. The manifesta tion of heterosis was strongest for some characters in the less favourable environment while for other characters a better envi ronment gave better heterotic effect.

    (Birsa Agricultural University, Ranchi, 1987) Birendra Kumar Singh; Dr. B. K. Singh
    The present investigation was conducted to compare the reproductive performance of three breeds of pigs viz. Large white Yorkshire, Landrance and Hampshire during three seasons. The relationship between reproductive efficiency and blood biochemical profile during different stages of reproduction was also studied. Furthermore, the changes in vaginal epithelium during different stages of oestrous cycle and pregnancy were observed using biopsy technique. 1. The average age at puberty in large white Yorkshire landrace and Hampshire was noted as 320.54, 1.95, 314.68, 1.62 and 316.52, 1.56 days. The influence of breed on attainment of puberty was significant (P-0.05). The influence of season on puberty attainment was also significant(p0.01) and gilts born during rainy season attained puberty earlier as compared to gilts born during winter and summer season. 2. The mean duration of oestrous cycle and average duration of oestrus did not differ significantly between breeds during different seasons. A significantly (p-0.01) higher occurrence of oestrus was recorded during winter (42.06 +0.47%) than summer (24.16=0.51) and rainy season (33.10 +0.49). 3. The mean duration of 1st, 2nd and 3rd stage of farrowing was 2.49 -.18, 2.27+.162 and 2.31 + 0.19 hours respectively. The total duration of farrowing was 5.46 +.628, 8.95 +.74 and 6.87 +.60 hours in large white Yorkshire, landrace and Hampshire respectively and the differences were statistically significant (P 0.01). The overall placental weight was 1.25 +0.54 Kg.
