This study was conducted to examine the effects of condensed tannins (CT) from Ficus bengalensis leaves on the feed utilization, milk production and health status of crossbred cows. Eighteen crossbred dairy cows at their second and mid lactation (avg. BW 351.6±10.6 kg) were randomly divided into two groups of nine each in a completely randomized block design and fed two iso-nitrogenous supplements formulated to contain 0% and 1.5% CT through dried and ground leaves of Ficus bengalensis. The diets were designated as CON and FBLM, respectively and fed to cows with a basal diet of rice straw to meet requirements for maintenance and milk production. The daily milk yield was significantly (p<0.05) increased due to supplementation of FBLM diet. The 4% fat corrected milk yield was also significantly (p<0.01) higher due to increased (p<0.05) milk fat in cows under diet FBLM as compared to CON. The inclusion of CT at 1.5% in the supplement did not interfere with the feed intake or digestibility of DM, OM, CP, EE, NDF, and ADF by lactating cows. Digestible crude protein (DCP) and total digestible nutrients (TDN) values of the composite diets were comparable between the groups. The blood biochemical parameters remained unaltered except significantly (p<0.05) lowered serum urea concentration in cows fed FBLM diet. There was a significant (p<0.05) increase intracellular reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activity in cows supplemented with condensed tannins. The total thiol group (T-SH) was found to be higher with reduction in lipid peroxidation (LPO) in cows of FBLM group. The cost of feeding per kg milk production was also reduced due to supplementation of Ficus bengalensis leaves. Therefore, a perceptible positive impact was evident on milk production and antioxidant status in crossbred cows during mid-lactation given supplement containing 1.5% CT through Ficus bengalensis leaves.

The paper explored the Traditional knowledge of rural women on processing of Shotti (Curcuma angustifolia; Family- Zingiberaceae) - a rhizome based ethnic weaning food, its collection patterns and temporal availability in the Uttar Dinajpur district of West Bengal, India. The information on preparation of weaning food and medicinal uses is based on the exhaustive interviews with local healers, practicing traditional system of medicine and elderly rural women. This knowledge is mainly confined to native people of North Bengal especially to the women of Rajbansi ethnic group. Details of the plant, parts used, method of preparation, dosage and mode of administration have been reported.

A field experiment was conducted during the rabi 2008-09 and 2009-2010 at the Regional Research Station (Hill Zone) of Uttar Banga Krishi Viswavidyalaya, Kalimpong (1250 m amsl), to elucidate the effect of different sowing dates and cultivars on yield of wheat (Triticum aestivum (L.) emend Fiori & Paol.). The experiment was conducted in split plot design with 3 replications with treatments comprising five dates of sowing viz. Nov. 1, Nov. 15, Nov. 30, Dec. 15 and Dec. 30 in main plots and 6 different wheat cultivar viz. 'HS 473', HPW 236, 'VL 875', 'HS 365', 'VL 832', 'PBW 343' and 'SKW 196' in sub-plots. Sowing on November 15, significantly influenced most yield attributes and was at par with November 30 sowing, but significantly superior to later sowings. The highest grain yield was obtained with November 15 sowing (2.79 and 2.49 t/ha), which was at par with November 30, and November 1 sowings in first year and in second year this was statistically similar with all date of sowing except extreme late sown condition. Sowing in mid November gave 14.9 and 26.2% more grain yield over December 30 sowing. Amongst the cultivars, 'HS 473' was found to be best and gave significantly more grain yield than 'HS 365' (2.93 and 2.74 t/ha) and was at par with 'VL 875' (2.86 and 2.50 t/ha) and 'PBW 343' (2.89 and 2.61 t/ha). More biomass production was recorded with early November 15 sowing, which was at par with November 30 sowing. Within the cultivars, maximum biomass production was recorded with 'HS 473' (7.78 and 7.28 t/ha) and was statistically at par with 'VL 875', "SKW 196" and 'PBW 343'. Uptake of NPK was most with 'PBW 343', which was at par with 'HS 473'. Maximum net return (24,926 and 23,192/ha, respectively) recorded with November 15 sowing, followed by November 30 sowing. This treatment also recorded higher B: C ratio (2.11 and 2.03, respectively). Amongst cultivars, maximum net return ( 26,986 and 24,368/ha) and B: C ratio (2.21 and 2.08) was recorded with cultivar 'HS 473' followed by 'PBW 343' and "SKW 196".

In the northern parts of West Bengal there is a good scope of growing of some minor, underexploited fruit crops along with the major fruit crops. Jalpai (Indian olive), latka (Burmese grape) and Panial (Indian plum/coffee plum) are three important minor fruit crops of this region. These fruits are mainly grown as homestead crops with no or very few management practices. Jalpai is most important among these minor fruit crops and found frequently in homestead cultivation. Jalpai (Elaeocarpus floribundus) belongs to the family Elaeocarpaceae and is a medium to tall tree. Flowers appear during April-May and fruits mature for harvest in August to October. Fruits are greenish in colour, single seeded, the shape resembles olive fruit. Matured jalpai fruits are used mainly for the preparation of pickles and chutney. Latka (Baccaurea sapida) belongs to the family Euphorbiaceae and is an evergreen, short to medium height plant. Sub-acid latka fruit is consumed fresh locally. The time of flowering is March-April and fruits are available during the rainy season, 3-4 months after flowering. Matured latka fruits are yellow or yellowish brown in colour. Panial (Flacourtia jangomas) belongs to the family Flacourtiaceae and is a short to medium tree having spines in the young branches. Flowers appear during April-May and fruits are harvested in August-September. A typical local practice is that after harvesting, the matured panial fruits are gently pressed in between the palms of both hand before fresh consumption. Ripe fruits are brown or brown red in colour. Panial fruits have good potential for preparation of jam.

The productivity, profitability and sustainable yield index were higher under blackgram - wheat and maize - wheat cropping sequence than the traditional rice - wheat sequence. Further, overall nutrient mining by this system was quite low compared to other sequences which are practiced in this region.
