The effects of brassinosteroid and N-(2-chloro-4-pyridyl)-N′-phenylurea either alone or in combination with benzyladenine on bunch parameters viz. bunch weight, berry weight, berry volume, and number of berries per bunch were evaluated on seedless grape variety 'Tas-A-Ganesh' (a clone of 'Thompson Seedless'). The growth regulator treatments were applied by dipping the bunches at either 7 or 15, or both 7 and 15 days after fruit set. The results showed that two dips, i.e., (7th + 15th) days after fruit set were more effective than single dips. The treatments having a combination of either higher or lower concentration of both BR (0.4 ppm) and CPPU (4 ppm) along with brassinosteroid 20 ppm produced maximum bunch weight (371.13 g), berry weight (4.90 g), berry volume (4.22), and number of berries per bunch (90.88). © 2011 Copyright Taylor and Francis Group, LLC.

Jeevamrit, a microbial culture, prepared especially from dung and urine of Indian cow is generally advocated for use in organic farming to meet the nutritional requirement of crops. Laboratory studies and field experiments were conducted to know the microbial composition and nutrient content of jeevamrit and its effect on the performance of rice (Oryza sativa L.)-wheat {Triticum aestivum (L.) emend. Fiori & Paol} and maize (Zea mays L.)- wheat cropping systems. The pH of jeevamrit prepared from buffalo, Indian cow and hybrid cow decreased from 8.32, 7.89 and 7.71 at the start to 3.86, 3.65 and 3.56, respectively after 5 days of incubation. The microbial count increased from its initial values in all the cultures. The bacterial count of jeevamrit prepared from Indian cow's dung and urine was highest followed by hybrid cow and buffalo, where as the fungal count was highest in jeevamrit prepared from hybrid cow's dung and urine followed by Indian cow and buffalo. Jeevamrit prepared from Indian cow and hybrid cow's dung and urine did not differ much in the microbial count (bacteria and fungi). The nutrient contents were 0.22, 0.04 and 0.60 g nitrogen, 0.11, 0.04 and 0.06 g phosphorus, 1.09, 0.28 and 0.75 g potassium and 0.46, 0.43 and 0.39 g sulphur in each litre of jeevamrit prepared from buffalo, Indian cow and hybrid cow's dung and urine, respectively; showing relatively higher contents of these nutrients in case of buffalo. The carbon content was more in jeevamrit prepared from dung and urine of Indian cow followed by buffalo and hybrid cow. The field application of jeevamrit over two years (2009-10 and 2010-11) neither alone nor in combination with chemical fertilizers or farmyard manure influenced the grain yield of rice, maize and wheat in rice-wheat and maize-wheat cropping systems indicating its inability to supply nutrients to the crops in needed quantities either directly or indirectly through mobilization of native nutrients from the soil.

Carry-over effects of paclobutrazol on various vegetative parameters of sweet cherry were studied. Paclobutrazol was applied on the basin of the trees as per trunk diameter during early spring and gibberellic acid was sprayed at full bloom. The treatment application was carried out during the first year only to assess carry-over effect during the next year. Trunk cross-sectional area, tree height and spread, tree volume, number of nodes on a linear shoot, and internode length decreased both in the year of treatment application and during the next year when no treatment was applied. Lowest increment in trunk cross-sectional area (3.37 cm),tree height (0.21 m), tree spread (0.17 m), and tree volume (3.33 m 3) during the carry-over year were recorded with the maximum concentration of paclobutrazol (0.3 g/cm). Maximum number of nodes (8.67) and shorter intermodal length (2.33 cm) were observed with 0.2 g/cm TD PBZ treatment, both of which are desirable parameters for better fruit set. © 2011 Copyright Taylor and Francis Group, LLC.

Results of an experimental study on the effects of different concentrations of wash load on the size of bed features and resistance to flow in a laboratory flume are presented. The experiments were carried out under different hydraulic conditions in a 30 m long, 0.204 m wide and 0.5 m deep tilting flume under clear water condition and in the presence of different concentration of wash load in the flow. The bed material used consisted of uniform sediment of size 0.96 mm. Analysis of the data indicates that the characteristics of the bed features change and friction factor increases in the presence of different concentration of wash load in the flow. The reasons for changes in the characteristics of the bed features and increase in friction factor in the presence of wash load are identified and a relationship for predicting friction factor in the presence of wash load has been established. © 2014 International Research and Training Centre on Erosion and Sedimentation and the World Association for Sedimentation and Erosion Research.
