Bihar Agricultural University, Sabour established on 5th August, 2010 is a basic and strategic institution supporting more than 500 researchers and educationist towards imparting education at graduate and post graduate level, conducting basic, strategic, applied and adaptive research activities, ensuring effective transfer of technologies and capacity building of farmers and extension personnel. The university has 6 colleges (5 Agriculture and 1 Horticulture) and 12 research stations spread in 3 agro-ecological zones of Bihar. The University also has 21 KVKS established in 20 of the 25 districts falling under the jurisdiction of the University. The degree programmes of the university and its colleges have been accredited by ICAR in 2015-16. The university is also an ISO 9000:2008 certified organisation with International standard operating protocols for maintaining highest standards in teaching, research, extension and training.VisionThe Bihar Agricultural University was established with the objective of improving quality of life of people of state especially famers constituting more than two third of the population. Having set ultimate goal of benefitting society at large, the university intends to achieve it by imparting word-class need based agricultural education, research, extension and public service.

    Application of BBCH scale for phenological studies in litchi in relation to temperature
    (Department of Horticulture (Fruit Science), BAU, Sabour, 2022) Aman, Ankita; Rani, Ruby
    Litchi (Litchi Chinensis Sonn.) of the sapindaceae family is one of the important sub-tropical fruit crops of India and require very specific climate for its successful condition. The growth, flowering and yield in litchi is greatly influenced by temperature. Phenology is the study of periodical plant development events and how they are affected by environmental conditions factors mainly temperature. In fact, changes in the time of phenophases of fruit trees are of great economical importance because they have direct impact on factors influencing final fruit yield. Phenological studies in litchi are also important for planned management of orchards and alerting litchi growers against environmental vagaries. BBCH-scale (BBCH = Biologische Bundesantalt, Bundessortenamt und Chemische Industrie) proposed by various workers has its own advantages of its simplicity and ease of use for annual, biennial and perennial plants and it also describes both the vegetative and reproductive stages of plant growth in sequential manner. Thus, an experiment was conducted to study the phenological development in litchi variety Deshi and Kasba using extended BBCH scale at experimental plot of Bihar agricultural University, Sabour that lies in indo gangetic plain of Bihar, India for three consecutive years from 2019 to 2021. The time, duration and prevailing temperature at each phenological stages of litchi were recorded as per extended BBCH scale in which 7 out of 10 principal stages were used, starting with bud development (stage 0) and ending with maturity of fruit (stage 8). Pictures of all phenophases were taken to see the morphological difference among them. Phenological development of all the stages of Deshi and Kasba was found significantly different in each year regarding their time of initiation and duration. The initiation of 1st vegetative flush started after 30-35 days in Deshi and 45-50 days in Kasba after harvest. The bud development (Stage 010) started in last week of June to first week of July in Deshi variety for 1st flush and first week of September for second flush. It was last week of July to first week of August in Kasba variety for first flush in both the year and first week of October for second flush. In variety Deshi phenological development was earlier in 2019 as Compared to 2020 and 2021 and it was delayed in 2020. Similar trend was noted in variety Kasba also. All stages of inflorescence were earlier in Deshi as compared to Kasba in each year of observation. It was also reflected that during 2020 all the mesostages was delayed in both the varieties. It was observed that prevailing temperature greatly influenced time and duration of particular phenophases in both the varieties. Positive correlation between maximum and minimum temperature with stages in both the variety was observed. Varietal difference was also observed in this regard and for stage 500, Deshi took higher temperature as compared to Kasba. However, all other stages, it was lower in Deshi as compared to Kasba. The principal stage flowering started earlier in Deshi than Kasba in all the years. But the phase duration of this stage did not vary much among the variety as it ranged from 30 to 32 days in Deshi and 28 to 33 days in Kasba during the year under study. Changes in leaf nutritional status in different phenological stages was also observed and highest Nitrogen (1.62 %) and Phosphorus content (0.27 %) was noted before beginning of stage 5 i.e. inflorescence stage and Potassium was maximum (1.25 %) at flowering stage. Similarly maximum carbohydrates (7.56 %) at stage initiation of stage 5 i.e. inflorescence stage. This study adds knowledge about year to year phenological development in relation to temperature. However, a long-term monitoring of litchi varieties for their phenophases and their relation to temperature is required to confirm the critical temperature for different phenophases and to see the phenological development in litchi with change in climate.

    Physico-chemical properties of Palmyrah palm (Borassus flabellifer L.) fruits grown in Bhagalpur district
    (Department of Horticulture (Fruit & Fruit Technology), BAU, Sabour, 2017-07) Aman, Ankita; Sengupta, Samik
    The palmyrah palm (Borassus flabellifer L) is a minor tropical fruit which belongs to family Arecaceae subfamily Borassoideae and genus Borassus. India stands first in the world in terms of its wealth of palmyrah palm with a population nearly 122 million palms (Vengaiah et al., 2012). It has great economic potential and every part of the palm is useful in one way or the other. The fruits, fruit sap, young tuberous seedlings of palmyrah palm are used as food. Despite this indisputable utility, with the exception of coconut, arecanut, date and oil palm, somewhat less attention has been given to the improvement of palms as compared to other tree crops. Palmyrah is extensively grown in Bhagalpur region mainly by the people of low income group. No systematic study on palmyrah palm has been undertaken. By keeping the above facts in the mind, an experiment entitled “ Physico-chemical properties of palmyrah palm ( Borassus flabellifer L.) Fruits grown in Bhagalpur district of Bihar” has been conducted at the Department of Horticulture (Fruit and Fruit Technology), BAC, Sabour during 2016-2017 with the objective to evaluate the physico-chemical quality of the fruit collected from Bhagalpur district. For this fruits were collected from different location and evaluation for the physical and biochemical parameters was performed. The results revealed that the average fruit weight of different accession of palmyrah ranged from 1192 to 1480 g. Fruit length and diameter differed significantly among all the different accession of palmyrah fruit. Steed weight varied from 406.70 to 533 g while it was highest in AC-1. Maximum pulp weight was recorded in AC-1 i.e. 590 g which was at par with AC-5. Significant variation was recorded in seed weight and it was highest in AC-15 i.e. 533 g and lowest in AC-10 i.e. 406.70 g. TSS differed significantly among the different accession of palmyrah fruit and highest TSS was recorded in AC-3 (15.96 oBrix ). Maximum acidity was found in AC-3 i.e. 0.97% and minimum in AC-13. Results also revealed significant variation in Total sugar, reducing sugar and non reducing sugar among all the accession of palmyrah fruit. Result revealed that phenols, antioxidant and carotenoids have been found non significant in palmyrah fruit but fruit is good source of antioxidant and carotenoids. It was found that range of antioxidant varied from 41.88 to 68.44 µmol TE g-1 among the different accession of palmyrah fruit. These findings will help breeders to take crop improvement programme in palmyrah palm and attract growers to grow palmyrah palm at commercial level.
