“…Irrigation and SR are two important factors that affect rice growth and yield (Ravisankar et al, 2014;Li et al, 2016;Kaur and Mahal, 2017;Yang et al, 2018). The present study indicated that CI delayed the peak time of rice tillering and decreased plant height, number of tillers, and yield compared with FI.…”

Straw returning (SR) is an important means of straw utilization, which has been tested and is helpful for improving soil fertility and crop production. However, the effects of SR on plant growth and yield of paddy rice (Oryza sativa L. subsp. japonica Kato) under water-saving irrigation (WSI) are rarely investigated. In the 2015 and 2016 rice seasons, field experiments were conducted with four treatments, namely controlled irrigation with conventional fertilization (CI-CF), controlled irrigation with straw returning (CI-SR), flooding irrigation with conventional fertilization (FI-CF), and flooding irrigation with straw returning (FI-SR). The objective of the present study was to investigate the response of plant height, number of tillers, biomass, and yield to SR and irrigation management. Results indicated that SR enhanced rice yield on average by 7.9% and 7.5% and improved irrigation water use efficiency (IWUE) by 6.3% and 8.3% in 2015 and 2016, respectively. The CI-SR combination significantly increased IWUE compared with FI-CF. These results suggested that SR could offset the inhibition of rice growth caused by CI, and the CI-SR combination could be an effective measure to enhance soil fertility, maintain the rice field, and increase IWUE. Furthermore, rice growth (plant height, number of tillers, and biomass) was slightly inhibited by SR during the first 20 d of the rice season, but increased after the jointing stage (approximately 40 d after transplanting). This implied that diverting some top-dressed chemical N fertilizer into basal application may be necessary for fertilizer management to better meet crop nutrient uptakes in rice fields with SR application, especially with CI.

“…These findings are in close agreement with Lakpale et al (2007). Growth and yield attributes were significantly influenced by irrigation and mulching in case of groundnut also (Ravisankar et al, 2014).…”

Influence of dates of sowing and irrigation scheduling on phenology, growth and yield dynamics of fenugreek (trigonella foenum greacum l.)

December using three irrigation levels. The results showed significant variation with different dates of sowing and irrigation on phenology, growth and yield of fenugreek. Sowing date had significant effects on seed yield and its components. Seed yield of fenugreek was also dependent on irrigation scheduling. Projected seed yield/hectare was maximum (1.37 and 1.4 t ha -1 ) on 2 nd November (17.66 and 17.9 g) with irrigation in all major growth stages. It may be concluded that to obtain higher seed yield fenugreek should be sown earlier at 2 nd November and irrigation should be given at seedling, branching, flowering, pod formation, pod development stages

“…The better development of crop under paddy straw mulch treatment was a result of better moisture availability, which maintained the internal water balance of the plant. Increase in yield is due to the increase in the yield attribute reported by Ravisankar et al, (2014). Among INM treatments, an application of 75% NPK+ 25% N through FYM + 60 kg S through gypsum recorded significantly the highest kernel and haulm yield followed by 75% NPK+ 25% N through vermicompost + 40 kg S through gypsum as compared to other INM treatments.…”

“…The surface mulch favourably influences the soil moisture regime by controlling evaporation from the soil surface (Patel et al, 2017). Irrigation at critical stages and moisture conservation with mulching practices can increase the land and water productivity along with profitability (Ravisankar et al, 2014).…”
