Crop disease remains a major problem to global food production. Excess use of pesticides through chemical disease control measures is a serious problem for sustainable agriculture as we struggle for higher crop productivity. The use of plant growth promoting rhizobacteria (PGPR) is a proven environment friendly way of controlling plant disease and increasing crop yield. PGPR suppress diseases by directly synthesizing pathogen-antagonizing compounds, as well as by triggering plant immune responses. It is possible to identify and develop PGPR that both suppress plant disease and more directly stimulate plant growth, bringing dual benefit. A number of PGPR have been registered for commercial use under greenhouse and field conditions and a large number of strains have been identified and proved as effective biocontrol agents (BCAs) under environmentally controlled conditions. However, there are still a number of challenges before registration, large-scale application, and adoption of PGPR for the pest and disease management. Successful BCAs provide strong theoretical and practical support for application of PGPR in greenhouse production, which ensures the feasibility and efficacy of PGPR for commercial horticulture production. This could be pave the way for widespread use of BCAs in agriculture, including under field conditions, to assist with both disease management and climate change conditions.

The field experiment was conducted to investigate the alleviation of the adverse effects of soil salinity in rice by efficient management of potassium fertilizers in coastal saline areas.The salt-sensitive (BRRI dhan28) and salt-tolerant (Binadhan-10) rice cultivars were used as test crops. The experiment was laid out in a randomized complete block design with three replications. There were thirteen treatment combinations viz. T0 (no K from MoP or SoP), T1 (K100 from MoP at final land preparation), T2 (K150 from MoP at final land preparation), T3 (K200 from MoP at final land preparation), T4 (K100 from MoP in two splits), T5 (K150 from MoP in two splits), T6 (K200 from MoP in two splits), T7 (K100 from SoP at final land preparation), T8 (K150 from SoP at final land preparation), T9 (K200 from SoP at final land preparation), T10 (K100 from SoP in two splits), T11 (K150 from SoP in two splits) and T12 (K200 from SoP in two splits). Muriate of potash (MoP) and sulphate of potash (SoP) were applied in two splits and during land preparation as per treatments. Binadhan-10 (salt-tolerant) rice producedhigher grain and straw yields than salt-sensitive (BRRI dhan28) one under saline conditions. Furthermore, application of potassium fertilizers resulted in significant increases growth, and grain and straw yields of both salt-sensitive and salt-tolerant rice cultivars under saline conditions. The nutrient (NPS) uptake and K+/Na+ ratio increased in both rice cultivars by application of potassium fertilizers under saline conditions. The higher amount of yield as well as nutrient uptake of both rice cultivars was observed when SoP was applied either in land preparation or two split doses. The K+/Na+ ratio was found to be higher in T9 and T12 treatments in salt-sensitive cultivar whereas T2 and T3 treatments showed higher K+/Na+ ratio in grain and straw of salt-tolerant rice cultivar, respectively. Therefore, the present study suggests that rice productioncould be improved in saline areas through application of higher doses of potassium fertilizers particularly split application of sulphate of potash.Progressive Agriculture 26 (2): 115-121, 2015

Drought tolerance is governed by constitutive and acquired traits. Combining them has relevance for sustaining crop productivity under drought. Mild levels of stress induce specific mechanisms that protect metabolism when stress becomes severe. Here, we report a comparative assessment of “acquired drought tolerance (ADT)” traits in two rice cultivars, IR64 (drought susceptible) and Apo (tolerant), and a drought-tolerant wheat cultivar, Weebill. Young seedlings were exposed to progressive concentrations of methyl viologen (MV), a stress inducer, before transferring to a severe concentration. “Induced” seedlings showed higher tolerance and recovery growth than seedlings exposed directly to severe stress. A novel phenomic platform with an automated irrigation system was used for precisely imposing soil moisture stress to capture ADT traits during the vegetative stage. Gradual progression of drought was achieved through a software-controlled automated irrigation facility. This facility allowed the maintenance of the same level of soil moisture irrespective of differences in transpiration, and hence, this platform provided the most appropriate method to assess ADT traits. Total biomass decreased more in IR64 than in Apo. The wheat cultivar showed lower levels of damage and higher recovery growth even compared to Apo. Expression of ROS-scavenging enzymes and drought-responsive genes was significantly higher in Apo than in IR64, but differences were only marginal between Apo and Weebill. The wheat cultivar showed significantly higher stomatal conductance, carbon gain, and biomass than the rice cultivars, under drought. These differences in ADT traits between cultivars as well as between species can be utilised for improving drought tolerance in crop plants.
