ABSTRACT: Flash flood or submergence is a common phenomenon in rice growing rainfed lowland areas that seriously affects crop establishment leading to severe yield losses. A few submergence–tolerant rice varieties have been developed by introgressing SUB 1 gene into mega rice varieties of South Asia. Performance of this variety can be further enhanced through adoption of appropriate management practices. One field experiment was conducted using Swarna- sub-1 during kharif, 2015 at Erasama block of Jagatsinghpur district. Results of this experiment revealed that the use of seeding density @50kg/ha, application of balanced doses of N-P₂O₅-K₂O @ 80-40-40 Kg/ha in transplanting aged seedlings significantly improved plant survival, yield attributing trials and grain yield. An additional N-dose of 20kg/ha at 7 days after receding of flood water resulted in better post submergence recovery and maximum yield..

ABSTRACT: The study was conducted on affected cattle which were selected on the basis of clinical signs, appearance of ticks, history and presence of Theileria diagnosed by thin blood films and Polymerase Chain Reaction (PCR). Total of 300 blood samples from cows and 2400 samples from buffaloes were collected from urban and peri urban areas of Hyderabad. Results revealed 90 % and 80% prevalance of thielarial infection in cow of urban and peri-urban areas respectively. Whereas higher percentage of infection was observed in cows at urban areas as compare to peri-urban areas of Hyderabad. Similar trend was observed in bufffaloes with 65% and 75% prevalance.............

ABSTRACT: Citrus black spot, which is caused by the fungus Phyllostictacitricarpa, affects almost all varieties of citrus and causes major problems in the commercialization of fruits in natura. To minimize the use of chemicals, biological control strategies have become increasingly attractive, and many Bacillus species have been reported to act as biocontrol agents. Therefore, this study aimed to elucidate the different mechanisms of action of bacteria against P. citricarpa. The production of antifungal substances (volatile, thermostable and cell-free molecules) and hydrolytic enzymes (β-1,3-glucanase and chitinase) werestudied............

ABSTRACT: Surveys of ratoon stunting disease (RSD) incidence in sugar cane crop (Sacharrum officinurum L) in Mumias were conducted between 2012-2016. Majority of farms constituted seed cane and commercial fields were randomly selected for survey purposes. Samples from 967 farms in four main growing zones including the miller-owned nucleus estate were collected and diagnosed. Multi-stage random sampling method was used to select 967 households, while purposive sampling was used to select commercial fields. The collected data was analyzed using descriptive statistics..............

ABSTRACT: Brown rice paddy is one of the germplasm untapped as a source of genetic diversity in breeding programs. This paper aims at describing the role of genetic parameters in determining the appropriate selection method in paddy (Oryza sativa L.) of brown rice. It is a descriptive method with data collection (literature) through books, journals, and scientific articles from previous studies. The finding shows genotype correlation coefficient value is greater than the correlation coefficient phenotypic; the genotypic correlation coefficient values is in line with the value of phenotypic correlation coefficient.............

ABSTRACT: In many farm animal species, the preference of a specific sex is obvious mainly due to commercial implications; so for comprehensive and efficient results in the livestock management plans specially breedingand selection programs, it is necessary to include acost-effective and reliable strategy for early determination of fetal sex. Several invasive and non-invasive approaches have been established for fetal gender detection in farm animals at early gestational age. Non-invasive determination of fetal sex based on analysis of cffDNA in maternal plasma would be a useful tool for management decisions andprovides opportunities for prenatal genetic diagnosis.............

ABSTRACT: The objective of this research was to increase the ethanol production of sweet sorgum stalks by panicle removal. This field experiment was conducted using a randomized complete block design with three replicates. The first factor was stages of panicle removal (50% booth, 100% flowering, and 50% grain filling) and non-panicle removal as control. The second factor was the variety of sweet sorghum (White Local Belu, Numbu, Kawali and Sugar Graze). Variables measured were seedling emergence, stages of 50% booth, 100% flowering and 50% grain filling, stalk fresh weight, juice production.............

ABSTRACT: A survey was conducted in ChalanBeel to determine the fish production and livelihood status of fish farmers for a period of thirty six months (July 2011-June 2014). The survey was conducted on 90 fish farmers of 52 villages under 3 Unions. Data were collected through personal visit and interviewsfollowing a detailed questionnaire. Total fish production from the ChalanBeel was 11999 tons in 2012, being comprised of 715.33, 3549.93, 3932.24, 3801.50 tones from river, beels, flood plain, and pond and borrow pitsrespectively. The total fish production in the ChalanBeel declined by 45% in 2012 compared to the production in 1982. Among the fish farmers 23.3% was illiterate where as 14.4.............

ABSTRACT: A pot experiment was conducted using P32 tracer technique at the Radioisotope Laboratory, Tamil Nadu Agricultural University, Coimbatore, during 2013-2014 to study the yield response of okra to P fertilization and its interaction with Zn. To study the fertilizer Zn use efficiency under varying levels of P, double tagging technique was employed using 65Zn and 32P as radiotracers. The treatments included four levels of P (0, 50, 100 and 150 kg P2O5 ha-1 applied as 32P labeled single superphosphate) and two levels of FYM (0 and 25 t ha-1), replicated thrice in a completely randomized design.............

ABSTRACT: This study investigated the factors that influence household wellbeing in oil and non-oil producing communities of selected states in Niger Delta. A multistage sampling procedure was used to select 454 respondents for the study. Structured interview schedule was used to collect data on respondents' and the data was analysed using descriptive statistics and multiple linear regressions at α 0.05. The study found out that the factors influencing household wellbeing were similar for both, except for livelihood activities in oil producing communities and access to livelihood resources being implicated in non-oil producing communities. The study recommends the need for government and relevant stakeholders to improve access to livelihood resources by rural households because of the significant and positive impact of these resources on wellbeing of rural households.
