The study was conducted at village level in Pabna milkshed areas of Bangladesh to asses the existing feed and fodder sources of cattle. The results showed that the overall number of cattle per farm family was 7.17 and chicken represents highest number (15.57) per farm family in this area. The results also indicated that during monsoon season the bathan is planted with Vigna mungo and Lathyrus sativus and average grazing hours per day varied from 1.1 in October to 5.6 in February. In Summer, they were offered naturally grown Cynodon dactylon with supplementary feeding of rice straw. The study further showed that the highest (65.7%) feed scarcity was found during mid April to mid May followed by mid June. The cultivation of Vigna mungo was highest (76.71%) compared to Lathyrus sativus by the farmers in the bathan areas. The major constraint to cattle production is the scarcity of quality feed during mid October to mid November.

The effect of supplementation of Jackfruit (Artocarpus heterrophyllus) tree leaves and mashkalai (Vigna mungo) barn on the intake and digestibility of freshly cut common grass by Black Bengal goats was evaluated. Twelve castrated goats of approximately 5-6 months age were randomly allocated to three dietary treatments: freshly cut common grass ad libitum, common grass+100g Jackfruit tree leaves and common grass+100g mashkalai bran. Although digestibilities of dry matter, organic matter, nitrogen and neutral detergent fibre were very similar in the grass alone and mashkalai bran supplemented goats but the values were significantly (P < 0.01) higher than those observed in the Jackfruit leaves supplemented goats. Supplementation of mashkalai bran promoted higher (p < 0.05) digestible nutrients intake with the consequent higher daily live weight gain (75 g) than those fed grass alone (31 g). It could be concluded that mashkalai bran could be a suitable supplement for goats consuming common grass in the tropics and subtropics.

Macronutrients ($Na^+$, $K^+$, $Ca^{2+}$, $Mg^{2+}$), yield and yield components, bioaccumulation and translocation of metal in plant parts of three Vigna species (V. cylindrica, V. mungo, V. radiata) were evaluated at 0, 50, 100 and $150mgkg^{-1}$ soil of Nickel (Ni). A marked inhibition (p < 0.001) in the distribution of various macronutrients was noticed in these Vigna species except for $Mg^{2+}$ content of the shoot and leaves. Similarly, all species retained more $Ca^{2+}$ in their roots (p < 0.05) as compared to the aerial tissues. Ni induced a drastic decline (p < 0.001) for various yield and yield attributes except for 100 seed weight. Toxicity and accumulation of Ni in plant tissues considerably increased in a concentration dependent manner. Vigna species signify an exclusion approach for Ni tolerance as both bioaccumulation factor (BF) and translocation factor (TF) were less than 1.0. The Ni content of plants being root > shoot > leaves > seeds. Scoring for percentage stimulation and inhibition (respective to control) at varying levels of Ni revealed tolerance of the species in an order of V. radiata > V. cylindrica > V. mungo. The acquisition of Ni tolerance in V. radiata seems to occur through an integrated mechanism of metal tolerance that includes sustainable macronutrients uptake, stronger roots due to greater deposition of $Ca^{2+}$in the roots, restricted transfer of Ni to above ground tissues and seeds as well as exclusion capacity of the roots to bind appreciable amount of metal to them. Thus, metal tolerant potential of V. radiata could be of great significance to remediate metal contaminated soil owing lesser impact of Ni on macro-nutrients, hence the yield.

The present study describes the ameliorating effect of $Ca^{++}\;on\;Cd^{++}$ toxicity on the germination, early growth of mungbean seedlings, nitrogen assimilation enzyme. s-nitrate reductase (NR), nitrite reductase (NIR), anti-oxidant enzymes (POD, CAT and SOD) and on the accumulation of hydrogen peroxide and sulphydryls. $Cd^{++}$ inhibited seed germination and root and shoot length of seedlings. While NR activity was down- regulated, the activities of NIR, POD and SOD were up- regulated with $Cd^{++}$ treatment. $Cd^{++}$ treatment also increased the accumulation of sulphydryls and peroxides, which is reflective of increased thiol rich proteins and oxidative stress. $Ca^{++}$ reversed the toxic effects of $Cd^{++}$ on germination and on early growth of seedlings as well as on the enzyme activities, which were in turn differentially inhibited with a combined treatment with calcium specific chelator EGTA. The results indicate that the external application of $Ca^{++}$ may increase the tolerance capacity of plants to environmental pollutants by both up and down regulating metabolic activities. Abbreviations: $Cd^{++}= cadmium,\;Ca^{++} = calcium$, NR= nitrate reductase, NIR=nitrite reductase, POD = peroxidse, SOD= superoxide dismutase, CAT= catalase, EGTA= ethylene glycol-bis( $\beta-aminoethyl ether$)-N,N,N,N-tetraacetic acid.

Objective: An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of crossbred lactating cows. Methods: Eighteen lactating crossbred (Bos taurus${\times}$Bos indicus) cows (body weight $330.93{\pm}10.82kg$) at their second and mid lactation (milk yield $6.77{\pm}0.54kg/d$) were randomly divided into three groups of six each in a completely randomized block design. Three supplements were formulated by quantitatively replacing 0, 50, and 100 per cent of dietary wheat bran of concentrate mixture with dried and ground foliage of black gram. The designated supplement was fed to each group with basal diet of rice straw (ad libitum) to meet the requirements for maintenance and milk production. Daily feed intake and milk yield was recorded. A digestion trial was conducted to determine the total tract digestibility of various nutrients. Results: The daily feed intake was increased (p<0.05) with the supplementation of black gram foliage. Although the digestibility of dry matter, organic matter, crude protein, and ether extract did not vary (p>0.05), the fibre digestibility was increased (p<0.05), which ultimately improved (p<0.05) the total digestible nutrients content of composite diet. Although, the average milk yield (kg/animal/d) and composition did not differ (p>0.05) among the groups, milk yield was increased by 10 per cent with total replacement of wheat bran in concentrate mixture with of black gram foliage. The economics of milk production calculated as feed cost per kg milk yield (INR 10.61 vs 7.98) was reduced by complete replacement of wheat bran with black gram foliage. Conclusion: Black gram foliage could be used as complete replacement for wheat bran in concentrate mixture of dairy cows in formulating least cost ration for economic milk production in small holders' animal production.

Dry matter(DM) accumulation in different plant parts of two Vigna spp., blackgram(Vigna mungo) and mungbean(Vigna radiata), was compared at different levels of salinity. Two vaarieties of each of blackgram (Barimash-1 and Barimash-2) and mungbean(Barimung-3 and Barimung-4) were grown with 50, 75 and 100mM NaCl solutions and tap water as a control till maturity. The DM accumulation in all plant parts of the two crops devreased with the increasing salinity levels. The reducation was severe in mungbean compared to blackgram. On an average mungbean produced only 3% grain yield compared to 37% in blackgram at 100mM NaCl. The salinity induced growth reduction was relatively less in Barimash-2 than that in Barimash-1. In mungbean, the relative DM production of Barimung-3 was greater than Barimung-4. The extent of biomass reducation due to salinity in different plant parts was not similar. At maturity the rank of biomass accumulation (at 100 mM NaCl) in different plant parts of blackgram was in decreasing order by seeds pod$^{-1}$ (97%), branch plant$^{-1}$ (88%), 1000-grain weight (79%), plant height(72%), pods plant$^{-1}$ (50%), leaf weight and root mass(both 49%) and stem weight (48%). In mungbean, the rank was in decreasing order by 1000-grain weight (57%), leaf weight (54%), plant height (52%), seeds pod$^{-1}$ (50%), branch plant$^{-1}$ (41%), root weight (34%), stem weight (24%) and pods plant$^{-1}$ (6%). Therefore, salinity reduced grain yield more than straw and roots of the Vignaq spp., and blackgram is relatively more salt-tolerant than mungbean.

Blackgram (Vigna mungo) is more salt tolerant than mungbean (Vigna radiata). This study was initiated to know whether the accumulation pattern of mineral ions in different plant parts plays a significant role in the differences in salt tolerance between the two Vigna species. Different mineral ions, viz. N, Cl, Na, K, Mg and Ca in different organs of two varieties of each of blackgram- Barimash-l (susceptible one) and Barimash-2 (tolerant one), and mungbean-Barimung-3 (tolerant one) and Barimung-4(susceptible one), were analyzed after growing with 0, 50, 75 and 100 mM NaCl solutions. The two crops showed a decreased but similar pattern of total N accumulation under saline conditions. The tolerant variety of both the crops showed a less reduction in total N than the susceptible one. Leaves showed the maximum while stem the minimum N, irrespective of levels of salinity. C $l^{[-10]}$ and N $a^{+}$ accumulation increased with the increasing salinity levels. Interestingly, similar to a halophyte, the salt tolerant blackgram exhibited conspicuously higher amount of N $a^{+}$ in the shoot than the salt-susceptible mungbean. However, the tolerant varieties showed less amount of N $a^{+}$ than the susceptible one, especially in blackgram. Seeds of both Vigna spp. accumulated the minimum amount of N $a^{+}$ than other plant parts. $K^{+}$ accumulation decreased by salinity in most of the plant parts, except seeds. Blackgram showed larger reduction in K than mungbean. The $Mg^{++}$ increased in leaves, petioles and stem by salinity while decreased in the roots, podshells and seeds in both the crops. Salinity increased $Ca^{++}$ accumulation in all plant-parts except roots of both Vigna spp. Apparently, the leaves of mungbean accumulated higher concentration of $Ca^{++}$ than blackgram. Varietal differences in the accumulation pattern of $K^{+}$, $Mg^{++}$ and $Ca^{++}$ were not clear. It was concluded that blackgram, presumably, possesses a similar salt tolerance mechanism to halophyte, and the pattern of accumulation of mineral ions in blackgram and mungbean was not fully ascribed to the differences in salinity tolerance between the two Vigna species.gna species.ies.s.ies.

Inoculation of the carrier-based mixed bioinoculants af N-fixer (Azospirillum lipoferum strain Az204/Rhizobium strain BMBS P47) and phosphate-solubilizing bacterium (Bacillus megaterium var phosphaticum strain Pb 1) promoted growth and yield of pearl millet and blackgram under pot-culture conditions. The mixed inoculant of Az204 and Pb 1 enhanced germination, seedling vigor, plant height, and seed weight, and resulted in $6\%$ increase in grain yield of pearl millet. Likewise, the mixed inoculant of BMBS P47 and Pb1 increased growth, nodulation, and yield in blackgram. The rhizosphere soil enzyme activities, including nitrogenase, urease, and phosphatase, in both pearl millet and blackgram were significantly increased by the inoculation of the mixed inoculant, compared to that of the individual inoculants. The results clearly indicate the beneficial effect of co-culturing the N-fixer and P-solubilizer in inoculants production.
