Water use efficiency and maximizing profitability of grain sorghum production in the Texas Panhandle

The reduction in the availability of irrigation water and the increase in pumping costs resulting from the decline in the Ogallala Aquifer make good management decisions more critical for the survival of the farm firm and the success of the agricultural sector in the Texas Panhandle. Response functions for irrigation and percentage potential evapotranspiration (PET) in the production of grain sorghum are estimated. The response functions are transferred into value product functions and combined with an irrigation energy cost function to determine the profit maximizing irrigation strategy. Three management decision variables; total water available, the level of irrigation and the water to meet crop ET requirements are evaluated. Grain sorghum yield, natural precipitation, irrigation, soil moisture content, potential evapotranspiration, and percent potential evapotranspiration (PET) data, collected over the period from 1998 through 2007 by commercial producers participating in the AgriPartners program are used to estimate the response functions. Results indicate that the optimum level of irrigation increases as the price of sorghum increases and decreases as the price of natural gas increases.Grain sorghum, ET, maximizing profit, irrigation efficiency, input use optimization, water conservation, Ogallala Aquifer, Texas Panhandle., Farm Management, Production Economics, Productivity Analysis, Resource /Energy Economics and Policy, Q12, Q15, Q25, Q32, and Q34,

Production Profitability of Ethanol from Alternative Feedstocks in the Texas Panhandle

The potential of three feedstocks: grain sorghum, sweet sorghum, and switchgrass for ethanol production in the top 26 counties of the Texas Panhandle Region is analyzed using yield and production costs of feedstock, processing cost of feedstock, final demand for ethanol, farm to wholesale marketing margin, and the derived demand price of feedstock. The calculated economic returns per acre of grain sorghum, sweet sorghum, and switchgrass are -$45.37, -$410.19, and -$150.17 respectively under irrigated condition and -$38.25, -$145.09, and -$29.04 respectively under dryland condition. The evaluation in this study demonstrates that ethanol production from grain sorghum, sweet sorghum, and switchgrass in the Texas Panhandle Region is not economically feasible given the current price for ethanol in Texas. This is consistent with the status of the ethanol industry in the Texas Panhandle.Ethanol production, Texas Panhandle, Grain sorghum, Sweet sorghum, and Switchgrass, Feedstock, Crop Production/Industries, Production Economics, Resource /Energy Economics and Policy, Q16, Q25, Q27, and Q42,

Possibility of using polythene lined ponds for Mariculture in sandy beaches

Vast stretches of sandy seashores are at present lying unutilised. These sandy areas are not suited for Agricultural operation. Neither are they considered suitable for aquaculture due to the porous nature of the Soil and resultant seepage of water. However, if this seepage of water could be prevented by some means these areas could be utilised for aquaculture purposes. Experiments have been conducted at the calicut Research centre of central marine fisheries research institute in this direction. These experiments have proved that the seepage of water through the soil could be prevented by suitably lining the ponds with black polythene film. Although the use of polythene film is quite prevalent in agriculture for various purposes, it has not so far been of much use in aquaculture. The conversion of these sandy shores into productive aquaculture ponds by providing polythene lining for them has shown bright possibilities of utilising extensive areas for aquaculture and a report on this method is presented here

Occurrence of mature Mugil cephalus along the Calicut coast

The mature Mugil cephalus has been reported from various parts of the country. This article reports on the observation of mature Mugil cephalus along the coast of Calicut for the first time. The observation on the mature Mugil cephalus from the Calicut coast is of interest especially in the context of renewed efforts to develop hatchery techniques for the species. It may be considered as one of the favourable conditions for development of hatchery at Calicut coast

Solution growth of Triglycine Sulfate (TGS) crystals on the International Microgravity Laboratory (IML-1)

An experiment was planned for the International Microgravity Laboratory (IML-1) to be launched around Feb. 1991. Crystals of triglycine sulfate (TGS) will be grown by low temperature solution crystal growth technique using a multiuser facility called Fluid Experiment System (FES). A special cooled sting technique of solution crystal growth will be used where heat is extracted from the seed crystal through a semi-insulating sting, thereby creating the desired supersaturation near the growing crystal. Also, a holocamera will be used to provide tomography of the three dimensional flow field and particle image displacement velocimetry to monitor the convective flows

Bibliography of the Indian Ocean 1931 – 1961 - A supplement to the ‘Partial Bibliography’

This Bulletin is a continuation of Bulletin No. 4 issued from this Institute as a Supplement (for the 1900-1930 period) to the ‘Partial Bibliography of the Indian Ocean’ brought out by the U. S. Program in Biology in 1962. In spite of various handicaps my colleagues have managed to bring together as many relevant references as possible for the 1931-1961 period, which did not find a place in the ‘Partial Bibliography’. There are in all 2682 references of which the greater part comes under fishes (827), crustaceans (418) and molluscs (293). The preparation of the Bulletin was undertaken at my suggestion by Messrs. R. S. Lal Mohan, D.B. James and K.K. Appukuttan who completed the same without prejudice to their routine work. It is needless to say that they had sacrificed a great deal of their spare time for this purpose and gives me great pleasure to record my sincere thanks and appreciation for their high sense of responsibility, co-operative spirit and devotion to duty. My thanks are also due to other members of the staff who in various ways helped in the completion of the Bulletin

Comparative assessment of Eli-Twist and TFO yarns

An attempt has been made to compare the properties of Eli-Twist yarn with those of conventional TFO yarn. Yarns ofthree compositions (100% Polyester, 50/50 Polyester/Cotton and 100% Cotton) were produced on Eli-Twist and ringspinning systems. Three different counts (39.4tex, 29.5tex and 23.6tex) from each composition have been produced,maintaining 40 twist factor for all the yarns. Hairiness, tensile strength, breaking extension, diameter, abrasion resistanceand coefficient of friction have been measured and then compared with those of conventional ring-spun TFO yarn. The massirregularity and imperfections are found more or less similar in both the yarns, while Eli-Twist yarn exhibits higher breakingstrength and breaking extension. Both coefficient of friction and abrasion resistance of Eli-Twist yarn are found to be low ascompared to ring- spun TFO yarn

Bibliography of the Indian Ocean 1900-1930 –A Supplement to the ‘Partial Bibliography’

The first Bulletin of the Central Marine Fisheries Research Institute on the “Bibliography of Marine Fisheries and Oceanography of the Indian Ocean 1962-67” was issued in March 1968 to provide the scientific workers in this region with a reasonably comprehensive list of references relating to the area since the issue of “A Partial Bibliography of the Indian Ocean” by the U.S. Programme in Biology in June 1962. It is most gratifying that the Bulletin was very well received. More than anything else this has enabled the outside world to get a correct idea of the extent of work carried out in this country in general and in this Institute in particular in marine fisheries and oceanography during the last few years. The usefulness of the venture has encouraged us to go ahead with the programme of preparation of a supplement to the “Partial Bibliography” as indicated in the Forword of the first Bulletin. However, owing to various practical difficulties it was not possible to cover the period from 1900-1961 in one Supplement as announced earlier and therefore to avoid delay it was considered expedient to issue the present one for 1900-1930. The Supplement for the subsequent period, viz., 1931-1961, will be issued in due course
