| dc.description.abstract | The present study “Dynamics of Maize Production Technology-A Macro Level Study” has been undertaken to examine growth in area, production, and productivity of maize in the state of Bihar. The study was based on secondary data. Maize is the third most important cereal crop in Bihar next to rice and wheat. In Bihar maize is cultivated in three seasonskharif, rabi, and summer. Especially during rabi, its production is high due to optimum temperature, long photo-period availablity, better nutrients, irrigation, cultural management, less infection of diseases and pests. In Bihar, maize is cultivated over an area of around 0.65 million hectares and produces 1.55 million tonnes of maize. Major maize producing dristricts in the state are Khagaria, Madhepura, Begusarai, Saharsa and Katihar. Winter (rabi) maize is cultivated mainly in Bihar with production of 1.02 million tonnes, about 65% of the total maize production in the state. This provides unique position to Bihar state in the national maize market with most of maize processing units in north India depending highly on maize from the Bihar state for a significant period of time. With the state productivity much higher than national level, area under maize cultivation is expected to rise as the availability of good quality maize offers significant opportunities for entrepreneurs in the state. The study revealed that the area under maize crop was 882 thousand hectares in 1980-81, which decreased to 600 thousand hectares in 2011-12.Percentage share of maize crop was estimated 8.02% in 2011-12. Growth rate of area was found maximum (5.72%) in zone II during period III and growth rate of production was comparatively larger (10.42%) in zone II during period I. Further the growth rate of productivity was ascertained maximum (7.94%) during period I of zone II. Co-efficient of variation in area for different periods under study was calculated to measure the stability in area of maize crop. Across the different zones, zone I alone showed relatively stable increase in area with co-efficient of variation at 10.16 per cent during overall period i.e. period IV. Variation in area between decade II and decade I showed that the percentage change was positive in zone II (19.88%) and negative in zone I, zone IIIA, and zone IIIB. Variation in area between decade III and decade II similar to that of decade II and decade I reported that the variation in area of maize was 29.15 per cent in zone II during decade III over decade II. It is evident that for the state as a whole, variation percentage was sharply declined within decade I (-21.10%). Within decade II, variation percentage was revealed positive (9.44%) in Bihar. Variation in area of maize within decade III was ascertained low as much as only 3.63 per cent. Analysis of inter-decennial variation in area of HYV maize reported that variation in area under HYV of maize between decade III and decade II was positive (4.23%) in zone II but in all other zones, the estimated variation percentage were negative. For the state as a whole, intra-decennial variation in area of HYV maize showed that variation percentage increased to 20.96% within decade III as compared to decade II. Among various problems of maize processing industries, erratic power supply was observed as the most severe problem with average score of 84.00 in Garret ranking, followed by problem of lack of technical knowledge, lack of improved machinery and lack of popularization of product with average scores of 61.00 , 57.80 and 56.60, respectively. | en_US |
