Agrometeorology and Agromet Advisory Service – Binod Kumar
1. Meteorological Research scheme (Non-Plan)
Recording of weather strictly as per IMD norms for all the observations for education, research and planning purpose since its inception of Meteorological Obsevatory in the year 1989 and now completed 23rd years of weather records at ZRS, Darisai.
Kharif Research Highlights:
1.1 A total rainfall of 531.6 mm with 36 number of rainy days ( rainy days > 2.5 mm) was recorded during kharif season (June –Sep 2010) having onset of monsoon rain with a condition of at least three days of rainy days amounting total rainfall of 20 mm or more and no dry spell of more than a week was on 27th of July’ 2010, delayed by 47 days as compared to normal day of monsoon rain onset (10th June).
Overall, during entire calender year 2010, a sum of 807.4 mm of raifall, which was lowest ever in 23 years of record since inception of meteorologial observatory in the year 1989 at ZRS, Darisai with negative deviation of 32.7 per cent against normal rainfall of 1200 mm accounting Meteorological, Hydrological, Agricultural and Socio - ecinomical drought. Considering, kharif season there were negative departure of rainfall viz. – 67.4, -57.5, -30.7 and -13.0 per cent registered during the month of June, July, August and September, respectively hampered not only Upland direct sown rice, transplanted Medium and Low Land rice covered 38, 534 ha of land area with total production of 16723.3 Metric Ton but also hinder cultivation of other cereal, pulse and oilseed crops hence, Contigent/ Alternate crops viz. Toria, Moong bean, Kulthi, Niger etc. were brought down to the door of farmers. In case of rainfall trend over the years (1989- 2010), there was a decrease of 6.16 mm of rain per year taking mean of 1253.7 mm.
1.2 Paper/Bulletin published :
Kumari Pragya, Wadood A. and Kumar Binod. 2009. Characterizaion of Climatic Normal and water balance of Kumari Pragya, Wadood A., Kumar Ramesh, Pandit S N, Kumar Sanjiv and Kumar Binod. Bulletin on Jalvau Pariwartan awam Krishi (tyok;q iforZu ,oa d`f"k) –under AICRP on Agrometeorology, Dept. of Agri. Physics and Meteorology2. Agromet Advisory Service (MoES – DAAS)
Weather forecast data for 5 consecutive days received from IMD Ranchi twice a week on Tuesday and Friday. Agromet Advisory bulletins prepared in local and english vernacular on the basis of next 5 days forecast and disseminated to the farming community through mass media.
Research Highlights :
2.1 During Kharif season( 2010) Maximum Relative Humidity was most accurate (90 %) followed by Cloud Cover (81%), Minimum Relative Humidity (77 %), Minimum Temperature and Wind Speed (56 %), Rainfall (43 %), Wind Direction (42 %), and least was in the case of Maximum Temperature (36 %).
► Agromet Advisory Service (AAS) at ZRS, Darisai centre prepared altogether 98 out of 104 Agromet Advisory Bulletins (AAB) covering 5 day’s weather forecasts and farming advisories during 20010–11 for 03 districts (East Singhbhum, West Singhbhum and Saraikela) of Jharkhand.
► The Agromet Advisory Service (AAS) were disseminated among the farmers through News paper, AIR, DD, ETv, DAOs, KVKs, ATMA, SAMETI , NGOs, IFFICO and KCC, etc.
► Now the prepared Agromet Advisory bulletin is being uploaded in local and english language at BAU Website viz. http:// baujharkhand.org and IMD website viz. http://imdagrimet.gov.in
Seminar/Awareness programme:
► Roving seminar/Awareness programme entitled “Climate Change and Agriculture”was conducted on 31.03.2010 at KVK assembly hall. A total of 70 Kisan mitra and 10 farmers were participated from 9 blocks of East Singhbhum and distributed rain gauge sponsored by IMD, Pune among 5 farmers of Ghatshila, Potaka, Musabani, Patmada and Jamshedpur Blocks of East Singhbhum. The chief Guest of inaugral session was Dr. Z. A. Haider Khan, Associate Director, Biotechnology and Chairman Dept. of Plant Breeding and Genetics, BAU, Kanke delivered his experiences on climate change followed by Dr. A. wadood, Chaiman, Dept. of Agricultural Physics and Meteorology, BAU, Kanke.
3. Organic Experiment :
3.1 Effect of On-Farm organic nutrient supply on cowpea (kharif) based cropping system(Cowpea-Wheat ).
Highest grain yield of 6.5 q/ha was recorded in the plot treated with preceeded crop of dhaincha along with equally incorporated neem and karanj cake supplied organic fertilizer @ 30 kg N /ha and was significantly superior over absolute control (1.4 q/h to each othea) while other organic nutrient combination were at par with superiority in FYM + Neem cake combination. Similar trend was also followed in yield attributing charaters.
3.2 Effect of On-Farm organic nutrient supply on Urdbean (kharif) based cropping system(Urdbean-Wheat ).
Plots treated with preceeded crop of dhaincha along with equally supplied neem and kranj cake furnished fertilizer @ 25 kg organic N/ha received highest grain yield (3.3 q/ha) with combination of 1/3rd quantity of FYM + Vermicompost + Neem cake each was significantly superior over absolute control (1.3 q/ha) treated plot . All other combinations of organic nutrient were at par followed similar trends in yield determing characters also.
