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: Black gram (Vigna mungo) is one of the most important pulse crops grown throughout the country. It is hardy crop and fixes nitrogen in soil. Organic black gram fetch higher price in market i.e., Rs. 175 whereas other receive Rs. 120. Vermiwash, is one among the organic manures which has high potential to increase the crop growth and yield. Thus, present study aims to evaluate the influence of vermiwash prepared from different combination of organic sources on growth and yield of black gram. Methods: The field experiment was conducted during kharif, 2018 at Organic Farming Unit, Rajasthan College of Agriculture, Udaipur, with nine treatments [T1= vermiwash from 100% cow dung, T2= vermiwash from 100% buffalo dung, T3= vermiwash from 50% cow dung + 25% dry farm waste + 25% green farm waste, T4= vermiwash from 50% buffalo dung + 25% dry farm waste + 25% green farm waste, T5= vermiwash from 90% green waste incubated with 10% cow dung, T6= vermiwash from 90% green waste incubated with 10% buffalo dung, T7= vermiwash from 90% dry waste incubated with 10% cow dung, T8= vermiwash from 90% dry waste incubated with 10% buffalo dung and T9= water spray (control)] and were replicated thrice in Randomize Block Design. Result: The result of experiment revealed that the application of vermiwash from 100% cow dung significant influence towards growth parameters and yield attributes thus achieved maximum seed yield, haulm yield and B:C ratio (2.3). On the basis of field performance, it may be concluded that the treatment T1(top dressing in two equal split application at the rate of 10% at initiation of flowering and 15 days after 1st spray) may be recommended as a better organic package of blackgram.

The experiment was conducted to clarify the growth and yield response of two rice cultivars, BR55 and BR43 under salt stress. Six different concentrations of NaCl viz 50, 100, 150, 200, 250 and 300 mM and distilled water (control) were applied on the rice cultivars which were grown under pot culture condition. Growth parameters like plant height, tiller number, leaf number and leaf area were negatively affected by salinity in both cultivars. Salt stress caused a significant reduction in yield in both cultivars of rice. Growth reduction was higher in BR43 than in BR55.The reduction in yield and yield parameters were found to be lower in BR55 than those in BR43. The results obtained in the present study suggest that BR55 showed higher salt tolerance than in BR43. Jahangirnagar University J. Biol. Sci. 7(2): 1-12, 2018 (December)

The present study aimed to the effect of different organic manures on the growth and yield attributes of cotton by conducting field experiments during rice fallow season of 2013-14 and 2014-15 at the Tamil Nadu Rice Research Institute, Aduthurai.. The cotton growth parameters such as plant height, leaf area index, dry matter production and monopodial branches plant-1 were significantly influenced by the application of 100% recommended dose of fertilizer through vermicompost (on equal N basis). Also application of recommended dose of fertilizer through vermicompost (on equal N basis) recorded significantly higher yield attributes viz., sympodial branches plant-1, number of bolls plant-1, boll weight and seed cotton yield (17.4 and 18.6 q ha-1 during both the years, respectively). Economic analysis also indicated that Insitu vermicomposting produced higher net returns with higher B:C ratio.

The response of blackgram (<i>Vigna mungo</i> L. Hepper) to two levels of elevated carbon dioxide (550 and 700 ppm) in terms of growth and yield was investigated and compared with ambient CO<sub>2</sub> level (365 ppm) using open-top chambers. The growth parameters viz., length and weight of root and shoot, root:shoot ratio, leaf area and weight significantly increased at 700 ppm CO2 when compared with 550 ppm. The percentage increase in total biomass at 700 and 550 ppm CO<sub>2</sub> was 65.4% and 39%, respectively compared to the ambient (chamber) control. The increase in total seed yield at 700 ppm (129%) was due to an increase in number of pods per plant and 100 seed weight, whereas at 550 ppm (88.7%) it was due to an increased number of pods/plant and seeds/pod. The results indicate variable responsive effects at different levels of CO<sub>2</sub> emphasizing the pertinence of research on elevated CO<sub>2</sub> in various agroecological inhabitations all over the world. The indication of higher responses for root and leaf at initial growth stages at the higher elevated level of CO<sub>2</sub> (700 ppm), which leads to better root establishment, achieving early photosynthetic efficiency and also better biomass production, and its improved partitioning can be reckoned as a positive aspect of increasing concentrations of CO<sub>2</sub> in atmosphere. The harvest index increased significantly to 35.7 and 38.4% at 550 and 700 ppm, respectively; it is a very important phenomenon in pulses for breaking the yield barrier.

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.

In semi-arid tropics, sugarcane yield and quality are affected by deficiencies in soil nutrients, including potassium and calcium. We examined the effects of two different potassium fertilizers, a traditional muriate of potash (MOP) and polyhalite (which contains potassium and calcium), on sugarcane growth, yield, and quality. Experimental treatments compared a control 0 kg K ha−1 (T1) to potassium applied as MOP only at 80 kg K ha−1 (T2) and at 120 kg K ha−1 (T3), and potassium applied as an equal split of MOP and polyhalite at 80 kg K ha−1 (T4) and at 120 kg K ha−1 (T5). Relative to the control the potassium-enhanced treatments had improved rates of key growth parameters, and of cane yields, which were 4.4, 6.2, 8.2, and 9.9% higher in T2, T3, T4,, and T5, respectively, than in T1. Regardless of fertilizer used, potassium applied at 80 kg K ha−1 achieved the highest sugar purity and commercial cane sugar content. All potassium fertilizer treatments had reduced (although non-significant) incidences of three key sugarcane insect pests. The economic benefits of polyhalite were reduced due to its higher cost relative to MOP. Combining MOP and polyhalite equally to achieve an application rate of 80 kg K ha−1 is recommended to enhance sugarcane growth and yield.
