Abstract: A field experiment was conducted to study the influence of different concentrations of foliar application of lignite humic acid (0.1, 0.5, 1.0, 1.5 & 2.0 percent) on rice. The application of humic acid upto 1.5 percent increased the grain yield of 4263 kg/ha markedly; beyond that level the grain yield was reduced. The uptake of N, P and K nutrients increased with increasing concentrations of humic acid dose foliar application 1.5 percent i.e, 59.4, 8.18, 13.9 kg/ha in grain for 1.5 percent HA compared to control of 48.9, 6.9 and 12.1 kg/ha, respectively. The N, P and K recorded in the straw were 30.1, 16.5 and 78.4 kg/ha compared to control of 26.1, 14.4 and 66.6 kg/ha, respectively.

Abstract: Field experiments were conducted during 2003-04 in two different seasons to know the influence of different organic manutes on growth and yield of garlic at Arabhavi, Belgaum district, Karnataka. Among the different manures, application of poultry manure @ 2.5 tonnes pwer ha-1 produced the tallest plants (52.2 cm), highest number of leaves (8.4), maximum leaf size (40.9 cm2), highest leaf area (34.5 dm2) and highest stem girth (5.21 mm). Application of poultry manure was on par with sunnhemp @ 20 tones ha-1 and vermicompost @ 5 tonnes pe ha-1 with respect to all the above characters, while the lowest values for all these parameters were recorded in untreated control. Application of sunnhemp @ 20 tonnes ha-1 produced the highest bulb yield (70.8 q/ha) and was on par with poultry manure @2.5 tonnes per ha-1 (68.4 q/ha) and vermicompost @ 5 tonnes per ha-1 (68.3 q/ha). The lowest bulb yield was recorded in untreated control (26.6 q/ha).

Abstract: Static renewal bioassay test was conducted to determine the toxicity of cadmium nitrate on the freshwater fish, Labeo rohita. The individuals were exposed to different concentrations of cadmium for 96 hr and the percent mortality was observed. The LC50 value was found to be 15 mg/l and one fifth of LC50 (3 mg/l) was selected as sub-lethal concentration for sub-acute studies. Behavioural patterns were observed in both lethal (1,2,3 & 4 days) and sub-lethal concentration (1,5,10 & 15 days). L. rohita in toxic media exhibited erratic and darting movements with imbalanced swimming activity, short jerky movements, surfacing and gulping of air, which might be due to the malfunctioning of neurotransmitters followed by hyper and hypo opercular activityl, loss of equilibrium, and mucus secretion all over the bod;y were obseved.

Abstract: A field experiment was carried out during kharif 2006-07 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to find out the influence of organic nutrient management on crop yield and soil biological activities in soybean. The field trial comprising of twelve treatment combinations of organics (viz., compost, vermicompost, GLM) and fermented organics (viz., beejamrut, jeevamrut, panchagavya). Microbial populations (viz., bacteria, fungi and actinomycetes) were significantly higher in treatments supplemented with organic manures in combination of either beejamrut + jeevamrut or beejamrut + jeevamrut + Panchagavya over RDF + FYM and treatments with fermented organics alone. Among the microbial populations, decreased trend of bacterial and fungal population was noticed from 30 to 90 days after sowing (DAS); however, actinomycetes population was increased. Similarly enzymatic activities (viz., phosphatase & dehydrogenaze) were significantly higher with supplementation of organic manures+fermented organics, and follows decreasing trend from 30 to 90 DAS. These enhanced biological activities helped in enhancing the soybean crop yield.

Keywords: Drought, Leaf morphology, Tomato
Abstract: Effects of drought on leaf morphology of tomato (Lycopersicon esculentum) were evaluated in the field experiment at Arabhavi, Karnataka. Experiment was laid out with two levels of irrigation and 50 tomato genotypes by adopting factorial randomized block design with two replications. Drought was imposed two weeks after transplanting in both the IW/CPE ratio (ration of irrigation water to cumulative pan evaporation) of 0.40 and 1.20 treatments. Irrigation was given when the pan evaporation reading reached 41.7 mm (1.20 IW/CPE ratio) and 125 mm (0.40 IW/CPE ratio). As the drought stress increased, there was reduction in leaf area, leaf area index, relative leaf expansion rate both length nad breadth wise as well as biomass at harvest to an extent of 28.9, 28.8, 28.5, 26.9 and 37.3 percent, respectively, while there was increase in specific leaf weightand specific leaf area was observed under severe stress of 0.4 IW/CPE ratio to an extent of 3.3 and 3.3. percent, respectively. Increase specific leaf weight indicates that under stress condition, leaf thickness has increased which is one of the drought adoptive mechanisms which was developed in tomato genotypes. Genotype L-31 attained faster leaf expansion rate both length wise as well as breadth wise. Genotype L-33 was able to produce more biomass even under the severe stress of 0.4 IW/CPE ratio as well as across the irrigation levels, which might be due to maintainance of higher leaf area as well as higher leaf area index.

Abstract: A field experiment was conducted to study the effect of Azospirillum and vermicompost on yield, nutrient uptake and economics of rabi sorghum in deep black soil under dry land condition at Bijapur. The study showed that apllication of Azospirillum @ 10 kg/ha along with 100% recommended nitrogen (N) recorded significantly higher grain yield (2713 kg/ha) and total N uptake (208.5 kg/ha). Nitrogen to the extent of 50% was saved due to application of Azospirillum either @ 5 or 10 kg/ha both with 50% recommended N. Vermicompost @ 2 t/ha substituted recommended N and Vermicompost @ 1 t/ha with 50% recommended N substituted half the recommended N. Phosphorus (P) uptake (9.54 kg/ha) was more with vermicompost @ 2 t/ha with 50% recommended N. The highest net return (Rs 11044/ha) was obtained by applying Azospirillum @ 10 kg/ha with 100% recommended N.

Abstract: Regeneration status of Leucaena leucocephala, known as the "Miracle tree" due to its paramount economic importance in semi arid zone of Jhansi has been evaluated. The work was carried out in 15 years old plantations of Leucaena at three sites. Edaphic factors showed that the soil moisture content and nutrient concentrations were relatively greater at perennial water stream (PWS) site than other sites. The study showed that the Leucaena tree, sapling and seedling density and canopy cover were the highest at perennial water stream (PWS) site whereas basal area was maximum (82.2 m2/ha) at Seasonal standing water (SSW) site and minimum at Leucaena plantation at forest (LP) site. The maximum above ground dry mass (22.4 g/m2) of understory vegetation was recorded at SSW site. Similar trend was observed in below ground (9.1 g/m2) and total dry mass (31.4 g/m2) of understory vegetation. The study revealed that Leucaena harboured maximum herb diversity and basal area of trees at low moisture content of the site i.e. seasonal standing water (SSW) site. Findings of the present study may suggest that the afforestation and revegetation trails by L. leucocephala at Bundelkhand region may show significant results not only in the production of fuel, fodder and wood but also may an effective tool for the promotion of diversity of understory vegetation in those area where precipitation and optimum moisture content is questionable. Therefore, Leucaena canopy on wasteland area may be value addition in forest regeneration program in semi arid region.
