Selection Of

The instintive behaviour exhibited by insects in the selecting  food is always a matter of  interests to entomologists, and it is one of the fundamental principles underlining the application of entomology to agriculture, horticulture and forestry. Food seclection is an important characteristic of insects that help them survive in periods with insufficient foods.Three grain types of food, maize grain, long-grain rice and soybean grain, were used in this sudy for detecting food selection behaviours of maize weevil, Sitophilus zeamais. Grains were kept in box traps put in the different stores in Son La during 90 days. The result showed that maize weevil, Sitophilus zeamais, prefered traps with maize grains (71.4%) considerably more than ones with long-grain rice (14.3%) and soybean grain (14.3%). Meanwhile, the cornsap beetle, Carpophilus dimidiatus, was mostly observed in maize grain (98.5%) and to a lesser degree, in soybean grain (1.5%); and the dried-fruit beetle, Carpophilus hemipterus, was abundantly observed in maize grain (93.1%) and less in soybean grain (6.9%). The red flour, Tribolium castaneum, also tended to select all the three food grain, i.e. maize grain: 53.5%, long-rice grain: 35.2%, and soybean grain: 11.3%.Comparing f beetle individuals captured on three types of food grains showed that the maize weevil, Sitophilus zeamais, is the most abundant species. The percentage this store beetle among all beetles observed in maize, soybean grains and long-rice grains were 57.0%, 84.9% and 27.6%, respectively. Interestingly, Ahasverus advena, foreign grain beetle, occurred abundantly on long-rice gain (61.7%), i.e. this grain is a suitable food for the development of this beetle.

Warehouses play an important role in storage of food grain articles in bulk. In India, these are basically owned by Food Corporation of India (FCI), Central Warehousing Corporation (CWC) and State Warehousing Corporations (SFCs). There is burgeoning issue of the improper storage of food grains now-a-days. In this article, an attempt has been made to study the storage capacity available with Central Warehousing Corporation for the period of nine years i.e. from 2005-06 to 2013-14. The data with respect to storage capacity available and its utilization have been collected and compiled from the annual reports of CWC. Moreover, an attempt has also been made to study the total storage capacity with Food Corporation of India and State Warehousing Corporations along with Central Warehousing Corporation. The study reveals that there has been no significant increase in the storage capacity as compared to increase in the procurement of food grains.

The geographical area of India is 3.29 × 106 km2 and the annual average precipitation is about 4000 km3 (about 1215 mm depth over the country). Large variations in agricultural practices, climate and land productivity result in large variations in agricultural productivity between states. Virtual water refers to the water required in the production of goods or services; exchange of water through goods and services is virtual water trade. This paper quantifies virtual water export/import from/to various states of India to/from a central pool related to trade of two major food grains, wheat and rice, during the years 2003–04 to 2005–06. Virtual water contents of wheat and rice were estimated for different states using the data pertaining to that state. It was found to vary from 745 to 9405 m3/t for wheat and from 2502 to 9562 m3/t for rice. Punjab, Haryana, Chattisgarh and Uttarakhand are net exporters of virtual water to the central pool; all other states are net importers. Among the virtual water exporters, Punjab and Haryana are water-stressed areas and some virtual water importing states have adequate water resources. Analysis shows that besides water availability, other factors are also important in determining virtual water export from a region.

The Presented study is an attempt to examine the trend and instability in area, production and productivity of food grain crops in Haryana and India during period 1966-67 to 2012-13 and five sub periods i.e. P-I (1966-67 to 1975-76), P-II (1976-77 to 1985-86), P-III (1986-87 to 1995-96), P-IV (1996-97 to 2005-06) and  P-V (2006-07 to 2012-13). The study is based on secondary data. The study reveals positive trends in area, production and yield of food grains for both Haryana and India. Production in Haryana and India increased mainly due to increase in yield. Similar results have been obtained on triennium bases. In Haryana, area, production and yield have shown positive growth rates in all the periods and the overall period except for area in Period-III, IV and V. In the case of India positive growth rates has obtained for production and yield of food grains while area has shown negative trend in Periods III, IV, V and entire period under study. The coefficient of variation (C.V.) in respect of the three components i.e. area, production and productivity of total food grains found to be higher in Haryana as compared to India in all the periods and the overall period except for yield in period-III, yield and production in period-IV and yield in Period-V. Similar results have been obtained for the instability indices.

Econometric Approach

This paper tries to recheck the determinants of food grains production in India. After the Green revolution & New economic policy reforms India has been self sufficient in food grain production. It is evident from the available literature that, there is a need of rechecking the causality amongst the factors in details. This paper uses VECM method to examine such relationships. Datas collected here are mostly of secondary nature.
