The experiment comprised of 3 planting density; normal distance sowing (P1), high density sowing fb alternate row harvesting for fodder at 35 DAS (P2) and high density sowing fb alternate row harvesting for mulch at 35 DAS (P3) in main plots and five treatments of nitrogen management [control (N0), 60 kg N ha-1 as basal (N1), 30 kg N ha-1 as basal + 30 kg N ha-1 as side dressing (N2), 75 kg N ha-1 as basal (N3) and 37.5 kg N ha-1 as basal + 37.5 kg N ha-1 as side dressing (N4)]. Maximum production efficiency (13.54 kg ha-1day-1), net returns (42213 ha-1) and monetary efficiency (338 ha-1day-1) were recorded under P2. Whereas, seed yield (1681 kg ha-1) was founded maximum in P3 treatment. The highest protein yield (326 kg ha-1) and water-use-efficiency (8.26 kg ha-1mm-1) were recorded from treatment P3 and consumptive water use (210.8 mm) and rate of moisture use (1.69 mm day-1) were realized from treatment P2. Among N-management treatments, N4 resulted in the highest seed yield (1893 kg ha-1), production efficiency (15.51kg ha-1day-1), net returns (52371 ha-1) and monetary efficiency (419 ha-1day-1). The same treatment also recorded highest grain protein content (19.70%), protein yield (373 kg ha-1), oil content (38.0%) oil yield (720 kg ha-1), consumptive use of water (211.7 mm) and water-use-efficiency (8.95 kg ha-1mm-1)
Potability of deep-well water sources in calbayog samar Philippines
No full textThe physico-chemical properties, microbiological quality and protective structures of deep-well water sources in selected urban barangays of Calbayog City, Samar, Philippines were evaluated. Results revealed that physico-chemical characteristics of deep well water sources in barangays Aguit-itan, West Awang, Central and East Awang in terms of pH, temperature and total dissolved solid passed the permissible limits of the Philippine National Standards for Drinking Water (PNSDW). However, turbidity, salinity, dissolved oxygen, biochemical oxygen demand and total suspended solids exceeded the PNSDW. For Microbiological analysis (MPN/100 mL) such as total coliform, E.coli and fecal coliforms, results were beyond the PNSDW. Water samples were contaminated with different microbial contaminants and not acceptable for drinking and cooking purposes. Deep-well water sources of the four selected urban barangays are not suitable for drinking if untreated but can be used for bathing and washing clothes. Protective structures help minimized adulterations but with the presence of houses nearby the deep-wells and the establishment of septic tanks in near houses may leak and contaminate the deep-well water source and could result to presence of fecal coliforms
Effect of edible oils on different stages of pulse beetle (Callosobruchus chinensis L.) on chickpea grains
No full textAmong the five edible oils viz. olive oil (Olea europaea L), coconut oil (Cocos nucifera L.), groundnut oil (Arachis hypogaea L.), mustard oil (Brassica spp L.) and sesame oil (Sesamum indicum L.) @ 3, 6 and 9 ml kg-1 grains were evaluated as protectants of C. arietinum against oviposition, adult mortality and adult emergence. Pulse beetles favoured untreated rather than treated grains. Similarly, irrespective of these oils, at the rate of 3 ml kg-1 was less effective in inhibiting the oviposition, adult mortality and adult emergence inhibition than 6 and 9 ml kg-1. Among the oils, coconut oil at 9 ml kg-1 grains was found to be most effective in inhibiting the oviposition (26.43 eggs), adult mortality (44.52%) and adult emergence inhibition (96.34%) and did not affect germination of chickpea grains till four months. Sesame oil also provided excellent results giving in the same parameters as 26.62 eggs, 40.95 and 96.08.percent, respectively. Oils of groundnut and olive were least effective in performing the above parameter in the process of the investigation

Zinc solubilizing plant growth promoting microbes produce zinc nanoparticles
No full textStrains of Pseudomonas, Bacillus, and Azospirillum with plant growth promoting ability were checked for their zinc solubilizing ability at ICAR-CRIDA, Hyderabad, India. Efficient zinc solubilizing microorganisms were evaluated for their ability to produce nano-scale zinc particles. The nanoparticles from the cell-free culture filtrates obtained from these strains were characterized for particle size, Zeta potential and functional groups. Presence of Zn nanoparticles in the bacterial culture filtrate was confirmed by particle distribution and Scanning electron microscope (SEM) analysis. Most properties of nanoparticles are size dependent. Zinc nanoparticles were observed to be spherical in shape and size ranged from 52.0 to 106.0nm. Zeta potential of the Zn nanoparticles was estimated to understand the stability of the particles. The measured zeta potentials varied from -14.5mV to +179.10 mV indicating high stability and dispersion of the zinc nanoparticles. FTIR peaks at different wave numbers depicted the role of functional groups of proteins in the biosynthesis of Zn nanoparticles. These results demonstrate the green synthesis of zinc nanoparticles by the plant growth promoting and zinc solubilizing strains of Azospirillum, Pseudomonas and Bacillus
