The study was conducted in Ratnanagar and Khaireni municipalities. A household survey of 100 banana growers which includes 50 from each municipality and of total 20 traders were interviewed for collection of primary data. Data obtained from semistructured questionnaire were subjected to descriptive analysis. The result showed that, the cost of banana cultivation per hectare was NRs 455857.80 and average profit to be NRs 197853.23 per hectare. The average benefit cross ratio was 1.50. Cobb-Douglas production function analysis showed that labor cost, machinery expenses, contributed significantly to gross income of banana at 1% level of significance. Organic manures and fertilizers costs contributed significantly to gross income of banana at 5% level of significance. Producers-Collectors-Wholesalers-Retailers-Vendors-Consumers supply chain was the prevailing supply chain in the study area. Most of the respondents perceived that the disease and pest infestation and fluctuation in price were major problems.

Gas flux was collected during critical stages of rice by static chambers installed in the field. Gas chromatography Varian 450 equipped with three different detectors was used for gas analysis. Results on greenhouse gases (GHG) emission revealed that drip irrigated paddy emitted lesser methane as compared to transplanted paddy in all stages of sampling. In tillering stage, both Hybrid CORH 3 and variety ADT 45 under drip irrigated system emitted lesser quantum of CH4 as compared to transplanted paddy (9.31 mg/m/day). Comparing two cultivars under drip system, variety ADT 45 emitted more CH4 (6.37 mg/m/day) than Hybrid CORH3 (3.97 mg/m/day). In case of CO2, drip irrigated paddy emitted higher CO2 during tillering stage (CORH3-4107.1 mg/m/day and ADT455184.2 mg/m/da...

Among the innovative water-saving techniques, drip irrigation is a forerunner, with maximized water-saving potential, increased grain yield and methane mitigation. A field experiment was conducted comprising four different drip Methods: irrigation practices: (i) sub-surface drip irrigation (SDI) with 1.0 litre per hour (lph) discharge rate emitters (DRE) (SDI+1.0 lph DRE) (ii) SDI+0.6 lph DRE, (iii) surface drip irrigation (DI) with 1.0 lph discharge rate emitters (DI+1.0 lph DRE), (iv) DI+0.6 lph DRE and were compared with (v) a conventional flood aerobic irrigation (considered conventional). The estimated grain yield of rice was found to be 23.5%, 20.3%, Results: and 15.1% higher under SDI+1.0 lph DRE, SDI+0.6 lph DRE and DI+1.0 lph DRE practices, respectively, than the conventional method. A water saving of 23.3% was also observed for all drip practices compared with conventional practices. Seasonal methane emission flux declined 78.0% in the drip methods over the conventional irrigation: better mitigation than previously reported values (alternate wetting and drying (47.5%) and system of rice intensification (29.0%) practices). Continuous soil aeration and enhanced soil methanotrophs (P<0.05) limit the peak methane emission in rice during the flowering phase in drip irrigation, which is reflected in the methane emission flux values. Consequently, the equivalent CO (CO-eq) emissions and yield-scaled CO eq-emission were found to be significantly lower in SDI (43.8% and 49.5%, respectively), and DI (25.1% and 26.7%, respectively) methods as compared with the conventional that ensures better methane mitigation and future climate-smart rice production systems. Drip irrigation could reduce the cumulative methane Conclusions: emission in aerobically grown rice. SDI + 1.0 lph DRE practice can be applied in areas with inadequate water availability and effective in reducing the CO-eq emission with better yield than conventional.

Effects of impulse drip irrigation systems on physiology of aerobic rice

Among the lateral distances, 0.8 m lateral distance adjudged as optimum spacing for better performance in terms of physiological responses as well as yield. Between two-discharge rates, 1.0 LPH drippers out performed 0.6 LPH drippers. Interactively, laterals spaced at 0.8 m with 1.0 LPH drippers exhibited best performance by way of physiological attributes [such as relative water content, chlorophyll stability index, soluble protein, photosynthesis (P N), stomatal resistance (g s), internal CO 2 concentration (C i), nitrate reductase activity and proline content], yield and its components along with water productivity. Therefore, it is suggested that the lateral spacing of 0.8 m with 1.0 LPH drippers with the plants spaced at 20 9 10 cm is the best treatment for aerobic rice cultivation in enhancing the grain yield and water productivity in the areas of limited water availability.

Evaluation of Drip Irrigation System for Water Productivity and Yield of Rice

Conventionally, rice is being grown under continuous standing water in all phenological stages except maturity. This method of cultivation of rice utilizes more than 30 to 45% of the world's fresh water resources (Humphreys et al., 2010). The conventional method of rice production is challenging in todays scenario due to water scarcity. The prevalent "water-saving" technologies such as "continuously saturated soil cultivation system", "the rice intensification system" (Uphoff and Randriamiharisoa, 2002) and "the alternate wetting and drying system" (Belder et al., 2004) are perceived to consume massive amounts of water (Geethalakshmi et al., 2011). The aerobic rice system is a water saving production system, where rice is grown under non-puddled and unsaturated (aerobic) soil (Bouman and Tuong, 2001), with supplementary irrigation under inadequate precipitation (Bouman et al., 2002, 2005). It reduces seepage, percolation, and evaporation compared to conventional irrigation method (Bouman et al., 2002). In contrast, numerous drying and wetting cycles are adopted in rice fields under aerobic cultivation causing a mild stress (Matsuo and Mochizuki, 2009; Malarvizhi et al., 2011). The superior irrigation management techniques coupled with suitable genotypes could improve the yield and water use efficiency of aerobic rice (Kato and Katsura, 2014). Precise application of water along with constant wetting techniques would be achievable under drip irrigation (Hanson and May, 2007). In addition, drip irrigation generally results in good crop development by limiting soil evaporation and deep percolation. Moreover, fertigation can improve yield potential of rice by applying split doses of fertilizers precisely at the right time in the right place (Adekoya et al., 2014). Also, physiology of the crop was significantly influenced by drip irrigation (Tognetti et al., 2003) with enhanced water, nutrient (Eid et al., 2013) and resource use efficiency (Rajwade et al., 2018). In another study, researchers observed that low discharge drippers, lateral

So, Background: the response of rice roots are to be phenotyped under varied drip irrigation treatments. This study describes an investigation on rice root Methods: phenotyping under drip irrigation treatments in split-split plot design. Two lateral spacing levels (0.8 and 1.2m), two depths of irrigation (5-10 and 15-20 cm) by solar powered and well operated irrigation were tested using TNRH 180, JKRH 3333 and ADT(R)45 rice genotypes during the summer season (2013 & 2014) in Coimbatore, India. Conventional aerobic irrigation was considered as control. An increased root length, root density (length Results and Discussion: and weight), root Adinosine Tri Phosphotase enzyme activity, root volume and filled grain percentage were favored in aerobic rice under the conditions of 0.8m lateral distance with 5-10cm depth of sub surface drip irrigation (SDI). Improved root characteristics were observed in JKRH 3333 rice hybrid, and root density and thickness favored the filled grains and yield increment in rice by drip irrigation. The 0.8m lateral distance laid out at 5-10cm depth SDI proliferated more roots at subsurface soil layer with significant yield increment in rice.
