Rice is the most widely grown crop in India. With the decreasing availability of water for irrigation, farmers are now switching towards water efficient production systems such as upland rice. Moisture stress at critical stages is one of the major reasons for low productivity of upland rice. So, the present study was conducted at college of Agriculture, Vellayani, Thiruvananthapuram, Kerala Agricultural University, Kerala, India. The experiment was conducted in RBD with nine treatments including two crop geometries viz., normal planting (20 cm x 10 cm) and paired row planting (10 cm x 10 cm) with 40 cm between paired rows, three rows of cowpea are grown in between two paired rows and in situ soil moisture conservation practices viz., live mulching of cowpea, hydrogel application and coirpith compost application were compared and analysed statistically on yield parameters and yield. Results revealed that, the treatment T9 (Paired row planting with live mulching of cowpea, hydrogel and coir pith compost application) favorably influenced the yield characters and yield of upland rice through proper conservation of moisture and improved availability of nutrients. The treatment T9 recorded the highest grain and straw yields of 3825 and 7700 kg ha-1 respectively with a harvest index (0.48) and was significantly superior to other treatments. It also recorded the highest moisture content in the soil as well as the maximum uptake and availability of nutrients.

Abstract AimsSoil water deficit in karst mountain lands is becoming an issue of concern owing to porous, fissured, and soluble nature of underlying karst bedrock. It is important to identify feasible methods to facilitate soil water preservation in karst mountainous lands. This study aims to seek the possibility of combined utilization of moss colonization and biochar application to reduce evaporation losses in carbonate-derived laterite.MethodsThe treatments of the experiments at micro-lysimeter included four moss spore amounts (0, 30, 60, and 90 g·m−2) and four biochar application levels (0, 100, 400, and 700 g·m−3). The dynamics of moss coverage, characteristics of soil surface cracks and surface temperature field were identified. An empirical evaporation model considering the interactive effects of moss colonization and biochar application was proposed and assessed.ResultsMoss colonization reduced significantly the ratio of soil desiccation cracks. Relative cumulative evaporation decreased linearly with increasing moss coverage under four biochar application levels. Biochar application reduced critical moss coverage associated with inhibition of evaporation by 33.26%-44.34%. The empirical evaporation model enabled the calculation of soil evaporation losses under moss colonization and biochar application, with the R2 values ranging from 0.94 to 0.99.Conclusions Our result showed that the artificially cultivated moss, which was induced by moss spores and biochar, decreased soil evaporation by reducing soil surface cracks, increasing soil moisture and soil surface temperature.Moss colonization and biochar application has the potential to facilitate soil moisture conservation in karst mountain lands.
