Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    Effect of nitrogen levels and seed rate on fodder productivity of rye grass (Lolium multiflorum)
    (AAU, Jorhat, 2018-07) Bora, Sarat Sekhar; Sharma, K. K.
    A field experiment was carried out at the Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat during 2016-2017. The experiment was laid out in split-plot design replicated thrice to assess the “Effect of nitrogen levels and seed rate on fodder productivity of rye grass (Loliummultiflorum)”. The treatments consisted of three different seed rates in main plot viz., 10 kg/ha, 15 kg/ha and 20 kg/ha along with four nitrogen levelsviz.0 kg/ha, 30 kg/ha, 60 kg/haand 90 kg/ha in sub-plots. It was revealed that effect of seed rates of rye grass was found to be significant on various growth and yield parameters. A seed rate of 20 kg/ha was found to be statistically superior in regards to growth parameters in all the three cuts viz. 1st, 2nd and 3rd cut as compared to15 kg and10 kg seed rate/ha. The highest green forage yield(330.30 q/ha) andcrude protein yield (6.21 q/ha)were obtained withseed rate of 20 kg/haand was significantly superior to 15 kg/ha and 10 kg/ha. The dry matter yield were also found to be significantly higher in seed rate of 20 kg/ha (71.88 q/ha). Effect of graded dose of nitrogen revealed that increasing levels of nitrogen from 0 kg to 90 kg/ha has sown positive trend in almost all the growth and yield parameters. Application of 90 kg N/ha resulted in higher values in almost all the growth and yield parameters. The highest green forage yield (381.43 q/ha) dry matter yield (83.179 q/ha) and crude protein yield (7.43 q/ha) were obtained in 90 kg N /ha and was found to be significantly superior to all other lower doses of nitrogen (60kg and 30 kgN/ha). Interaction effect of seed rate and nitrogen levels were found to be significant in respect of important parameters like plant height,tillers/m2, green forage yield,drymatter yield and crude protein yield. Economic indices indicated that the highest net return ofRs. 51253.00and B:C ratio of 1.58 were recorded in 20 kg/ha seed rate as compared to other lower seed rate (15 kg and 10 kg/ha).In case of nitrogen levels, higher net return was founddue to application of 90 kg N/ha (Rs. 48777.00/ha) with B:C ratio of 1.59. The present investigation revealed that rye grass as rabiforage crop responded positively to increase levels of seed rate and nitrogen in respect of forage productivity and quality. Application of 20kg /ha seed rate in combination with 90kg N/ha has been found to be more productive and profitable in rye grass.
