Pulses are one of the most important legume crops in India contributing significantly high quality protein. Among the legumes, black gram (Vigna mungo L. Hepper), is an important legume crop in our country belonging to the family leguminoceae. The low productivity in pulses may be due to the fact that they are normally grown in marginal lands with inadequate soil moisture and poor fertility status. To increase yield under these circumstances, integrated seed treatment is given as a presowing treatment. Hence, a study was attempted to find out the influence of integrated seed treatments on growth and yield parameters in black gram. The seeds of black gram cv VBN 4 were subjected to various seed treatments and treated seeds along with the control were evaluated for their seed quality, growth, gas exchange and yield parameters both in laboratory and field trials. The study revealed that seeds fortified with MgSO4 + polykote + carbendazim + dimethoate + bioinoculant (Pseudomononas fluorescens) + Rhizobium + Azophos + pelleting with DAP recorded higher seed yield and other parameters when compared to control.

Black gram (Vigna mungo L.) is a vital pulse crop globally and one of the most vital pulse in India. It is understood to be affected by many varieties of diseases, Cercospora leaf spot is certainly considered one among them. Cercospora leaf spot due to Cercospora canescens causes much damage to the production of black gram. The neem cake, Trichoderma viride, Pseudomonas fluorescens, Paecilomyces lilacinus, Carbendazim were tested under field conditions during Rabi 2020-2021 for their efficacy against the disease and growth and yield parameters. A survey was conducted during Rabi, 2020-2021 to know the severity of Cercospora leaf spot of black gram in farmer’s fields in Kurnool district of Andhra Pradesh. In-situ (field) experiment was carried out in randomized block design with five treatments and three replications. The highest plant height at 60 DAS (56.96 cm), fresh weight (35.59 gm), dry weight (14.98 gm), number of pods per plant (18.17 pods/plant), yield (7.96 q/ha) and Benefit Cost ratio (1:3.48) showing better result when treated with treatment neem cake @ 0.5 t/ha + Trichoderma viride @ 2.5 kg/ha.  The treatment T1 – neem cake @ 0.5 t/ha + Trichoderma viride @ 2.5 kg/ha significantly decreased the disease intensity at 30, 45 and 60 DAS (10.02%), (12.02%) and (16.42%) respectively. It is concluded that T1 – neem cake @ 0.5 t/ha + Trichoderma viride @ 2.5 kg/ha found superior in all the growth and yield parameters.

Abstract The present study investigates the chromium (VI) induced phytoxicity and accumulation in the black gram (Vigna mungo L. cv. BVN-3) grown under refined sand pot culture. The phytotoxicity assessed with reference to growth behavior, water transport, metabolic alteration, yield, uptake and translocation of S, P, Fe and Cr under chromium (VI) stress. The black gram plants were treated with varied chromium (VI) at 0.00, 0.05, 0.10 and 0.25 mM concentration. After 5 d of Cr (VI) treatment, the foliar toxicity symptoms showed as loss of turgor and chlorosis of older leaves which also reflect in middle aged leaves later on at higher concentration of chromium (0.25 mM). At the later stage, chlorosis symptoms became critical and distorted to necrosis in patches with tapered lamina, thin tendrils and loosed coiling property. Cr (VI) induced toxicity observed on black gram as decreased growth and yield, impairment in photosynthesis activity, inhibition of metabolic and enzymatic activities and nutrient imbalances. Excess (0.25 mM) of Cr (VI) also caused a reduction in uptake and accumulation of iron in the leaves as compared to control (from 426.2 to 198.7 µg g-1 dw) with more uptake and accumulation of sulphur and phosphorus. Higher accumulation of Cr was recorded in the leaves (166.5 µg g-1 dw) followed by roots (123.4 µg g-1 dw) and stems (46.6 µg g-1 dw) at 0.25 mM after 29 d of treatment. Therefore, consumption of Cr containing black gram may have human health concern due to toxic Cr accumulation and nutrition imbalances.

Background: Composting is the process of breaking down of organic matter using living organisms which can be used as manure for soil conditioning. Vermicomposting is the rapid decomposition of biowastes using earthworm species which will enhance the growth and yield of plants. Methods: The vermicomposting of vegetable and fruit wastes was carried out during summer season (May-July) and by using the vermicompost a pot culture experiment was conducted in black gram for three months from August to October, 2019. The treatments consist of combinations of vermicomposted wastes and cowdung along with bioinoculants, Soil served as control. The biometric parameters such as root length, shoot length, fresh weight and dry weight on 15, 35, 55 DAS and yield characters like number of pods/plants, number of seeds/pods, pod length, weight of seed/pod, pod fresh weight and pod dry weight were recorded and statistically analysed. The present study has been attempted to convert the vegetables and fruit waste into compost as manure and analyse its effect on vegetative growth and yield parameters of Black gram (Vigna mungo L.). Result: The highest value of shoot length, root length, fresh weigh and dry weight were noted in fruit waste + cow dung + Pleurotus eous (APK1) + Trichoderma asperelloides + Eudrilus eugeniae on 15, 35 and 55 day after sowing (DAS) and the least was reported in control (only soil). The application of T8 treatment reported the highest yield characters which were followed by other treatments and control on 15, 35 and 55 DAS. The study concluded that T8 (F.W + cow dung + P. eous + T. asperelloides + Eudrilus eugeniae) is an effective biocompost for the growth and yield of black gram (Vigna mungo L.) which is eco-friendly.

Background: Black gram (Vigna mungo. L) is one of the most cultivated legume pulse crop with high nutritive value and Malabar neem (Melia dubia) is an emerging industrial agroforestry tree in Southern India. To maximize the land utilization with a field experiment was conducted at Western zone of Tamil Nadu to investigate the performance of black gram varieties under different spatial arrangements of Melia dubia plantations. Methods: An agroforestry trial was laid out in randomized block design (RBD) with eight treatments and three replications during kharif and rabi (2019-20) season. Black gram crop varieties (V1 - CO6 and V2 - VBN 6) were intercropped with M. dubia (1.5 year old plantation) with three different spacing of S1 (3 x 1.5 m), S2 (3 x 3 m) and S3 (4 x 4 m) while S0 as open field (Sole crop of black gram) for both the season. Result: The results of pooled analysis of two season shown that, treatment S0V2 recorded plant height (49.96 cm), number of branches (3.76), number of leaves (259.75), number of flowers (53.44), number of pods (22.85), seed yield per plant (5.38 g) and seed yield per hectare (0.82 tonnes) in open condition. Similarly in intercropping the growth and yield attributes of black gram were minimum performance recorded in CO 6 at closer spacing (3 x 1.5 m). In tree growth maximum pooled height increment (1.57 m) was observed in closer spacing (3 x 1.5 m) and maximum diameter recorded in wider spacing of both varieties. Hence wider spacing of S3 (4 x 4 m) can be suggested for intercropping under M. dubia plantations upto 4 years.

Under high salinity conditions, plant growth promoting halophilic bacteria (PGPHB) can thrive and greatly encourage plant growth. The use of PGPHB is minimal and less discussed in sustainable agriculture and abiotic stress control. The focus of the current investigation is to improve the growth of black gram by inoculating with of halophilic bacteria under salinity stress. Four PGPHB bacteria, viz., Bacillus safensis strain Lewis_Bac_3 (HB-5), Pseudomonas stutzeri strain MN1 (HB-13), Staphylococcus xylosus strain C5 (HB-18) and Pseudomonas sp. (GP-21: reference strain) were inoculated to black gram seeds to evaluate their plant growth promoting ability at 4 dS m-1 and pH >8.5. Increase in root length, plant height, and number of branches have been reported in consortium treatment (T8), indicating that salinity does not affected black gram photosynthesis and nutrient absorption in consortium treatment. Corroborating evidence revealed higher nodulation and total nitrogen and phosphorous content in the same treatment, in comparison with control. Due to salinity stress, decreased blooming was reported in control, conversely, consortium treatment showed 29.3 flowers/plant. A positive correlation with yield was demonstrated by number of pods and seeds per pod of black gram. In addition, there is a strong association between pods per plant and the amount of flowers per plant, nutrient content, and length of root. The decrease in control plot yield was due to shoot and root development resulting from insufficient nutrients availability. In this study we also found positive correlation between% P in plant and yield. Hence, we conclude that PGPH bacteria helps in the reduction of salt stress and significantly increase black gram growth and yield under mild salinity stress.
