    Effect of Pre-Sowing Seed Soaking On Rice Productivity under Upland (Rainfed) Condition
    (Birsa Agricultural University, Ranchi, 2002) Manoj Kumar; A.K.Verma
    Rice ( oryza staviya) I sone of the popular staple food crop in. India has largest area 40.2 million hectare followed by china and Bangladesh. Rice is primiarly a high energy or high calorie food .Rice, is primarily a high energy or high calorie food . However compares favorably who other cereals in amino – acid content . The biological value of this protein is high It is rice in Vitamin B and many other minerals with little amount of calcium It is commonly grown in almost all parts of plain sand plateau regions. Seed is protector and propagator of its kids and has paramount important in seed production. Seed production is affected by number of factors among these germination of seed play vital role , germination of seed decides the vigour health and good crop stand of the rive a little work has seed done on the effect of seed soaking under upland rainfed conditions of plateau region. Keeping these point in view an experiment entitled Effect of pre-sowing seed soaking on rice productivity under conditions was planned. The experiment was conducted in split plot desing and replicated thrice. Recommended dose of fertilizer was given in all the treatment and all due cares were taken during the period of investigation. The seed soaking (18hr water soaked) proved beneficial for getting higher percentage germination growth and yield .Maximum germination plant height number of spikelets number of filled grains number of seeds per plant 1000 – grain weight and grain yield were obtained by the use of 10 hr water soaked seeds. Minimum days to first flowering and 50% flowering were obtained by the use of 10 hr water soaked seeds. Maximum days for germination and 50% flowering were obtained when dry seeds were sown. Maximum Number of panicle (X1000/m2), Number of Spikelets (X1000/m2), number of filled grains (X1000/m2) were recorded by the rice genotype IET-15296 when 18 hr water soaked seeds were sown . Maximum percentage of filled grained was recorded by the rice genotype IET-15330 when 18 hr water soaked seed were used. Highest grain yield (451.50g/m2) was obtained by the rice genotype IET-15295 under 18 hrs water soaked seeds. The harvest index was maximum in rice genotype Birsa Gora 102(60%) when 18 hrs water soaked seeds were sown.

    Effect of Different Levels of Phosphate on Growth Parameters and Grain Yield Of Urd Bean (Vigna Mungo L.Hepper) Under Plateau Region of Chotanagpur
    (Birsa Agricultural University, Ranchi, 1998) Kishto Kumar; Dr.A.K.Verma
    The Mango because of its great utility occupies a prominent place amongst the fruits crops of India and is acknowledged as the national fruit of our country. Bihar ranks next to U.P in area and production of mango, Since mango is a cross pollinated crop, vegetative propagations of paramount importance for this crop. Although inarching is still the chief technique of propagation in Bihar, but due to several disadvantages of this method, now-a- days the detached methods such as veneer, soft wood and stome grafting are being strongly advocated. The information available on the comparative performance of these detached methods at the nursery stage and also on the establishment in the nursery under agro-climatic conditions of chota Nagpur region and lacking. Very little work has been done to standardize the period of defoliation and storage of bud wood for this region. With a view to evaluate the different techniques of detached methods of grafting for Dashehari mango and to find the best defoliation and storage period, the present study was undertaken at Ranchi Agril. College kanke, during the monsoon season of 1991 and repeated in 1992. For this study three different sets of trials were conducted with action shoot of Dashehari mango under randomized block design. There were altogether 9 treatments in each set and were replicated thrice. There were 3 defoliation periods (6, 8, and 10 days) 3 storage period(0, 3 and 6 Days).

    Studies on Physiological Basis of Higher Productivity of Upland Rice
    (Birsa Agricultural University, Ranchi, 1997) Manoj Kumar Singh; A.K.Verma
    In order to study the physiological basis of higher productivity of upland rice, twelve rice varieties were tested under upland conditions during Rainy season of 1994 in a randomized Block design with three replication. The experiment was conducted at Birsa Agricultura l university farm,Kanke ,Ranchi. The finding of experiment were summarized below. 1. The variety Birsa Gora 102 attained maximum height at all the growth stages as compared to other rice varieties. 2 .Maximum number of effective tillers per plant were produced by the rice variety BD 101 followed by Birsa Gora 102. 3.BD 101 and Birsa Gora were found to be on a par in producing longer panicles. 4. The rice variety BD 101 recorded highest panicle weight (3.32g) followed by Birsa Gora 102 (2.83g) and both are found to be significantly superior then rest of rice varieties teste 5. Maximum number of filled grains (93) was recorded by the variety BD 101 which was followed by the variety Birsa Gora (84). 6.The rice variety BD recorded highest grain weight (1.63g) followed by the variety Birsa Gora 102(53g). 7.Maximum test weight was recorded by the variety BD 101 which was significantly superior than the rest of the varieties. 8. Maximum grain yield was recorded by the variety BD 101(15.9q/ha )and found to be significantly superior than the rest o varieties tested. 9.BD 101 produced maximum straw yield followed by Birsa gora 102 and was significantly superior than the rest of the rice varieties. 10.The harvest index was maximum in rice variety BD 101 (36.87%) and found to be significantly superior to rest of the varieties tested.This was followed by the variety Birsa Gora 102(36.08%). 11The variety BD 101 attained maximum leaf area at all the growth stages as compared to other varieties tested. 12.The maximum dry matter accumulation was recorded by the variety BD 101 at both the stages and found to be significantly superior to rest of the verities tested. 13.Net assimilation rate was maximum inBirsa Gora 102 and found to be significantly superior to rest of the rice varieties tested. 14. The rice variety BD 103 attained higher leaf ratio at both the stages of growth. 15. Maximum relative growth rate was recorded by the rice variety BAU 146-16-3 followed by BAU 125-4-1. 16.The highest percentage of good quality seed was recorded by variety BD followed by Birsa Gora 102.The maximum percentage of chaff was obtained by variety BD 202.

    Effect of Nitrogen on Grain Filling And Yield In Upland Rice
    (Birsa Agricultural University, Ranchi, 1996) Lakbindra Puran; A.K.Verma
    It is rather difficult to give definite conclusion on the basis of one year’s experimental data. An attempt , however has been made to draw broad indications under the conditions of present experimentation. On the basis of the results obtained the following conclusion can be drawn. The variety Birsa Gora 102 gave highest yield at 45 Kg/N/ha (applied as three equal splits i.e. 1/3at sowing and 1/3 after 48 days of sowing)followed by BD 106 under upland condition of Bihar plateau.
