“…In herbicide treatment the higher weed control efficiency were obtained with the application of pendimethalin at the rate of 1 kg ha -1 at 3 DAP fb Hand hoeing + pendimethalin at 1.5 kg ha -1 on 30, 90,150, 210 DAP (T 2 ) (Table 2) these might be due to periodical removal of weeds and poor germination of weed seeds. These result similar with the findings of Anil Kumar et al, (2012) in gladiolus. The WCE was lowest in the unweeded check (T10).…”

“…Padmapriya et al, (2008) observed that weed management caused significant improvement in economic returns of cassava. Also reported by Kumar et al, (2012) found that application of pendimethalin along with hand weeding proved to be economical. In case of interaction between fertility levels and preemergence herbicides it was found nonsignificant effect due to different levels of treatments.…”

The field experiment was conducted during the year 2017 under All India Co-ordinated Research Project on Tuber Crops at S.G. College of Agriculture and Research Station, Jagdalpur, IGKV, Raipur (C.G.). The experiment was laid out in split plot design with two factors namely fertility levels and different pre-emergence herbicides with three replications. The result revealed that weed species, weed population and dry weight of weed were recorded significantly maximum under F 5 (130% NPK) followed by under F 4 (115% NPK), weed control efficiency were not affected by any fertility levels treatment. In case of application of pre-emergence herbicides whereas the weed species, weed density and dry weight of weed were significantly higher in T 6 (weedy check) whereas, weed control efficiency was recorded significantly higher in T 2 (Pendimethalin @ 1.5 kg a.i. ha -1 ) at 30 and 60 DAP. However, net returns and benefit cost ratio was recorded significantly maximum under F 5 (130% NPK) followed by F 4 (115% NPK) and minimum was observed under F 1 (70% NPK) in fertility levels. In case of pre-emergence herbicides recorded significantly higher under T 2 (Pendimethalin @ 1.5 kg a.i. ha -1 ) and lowest was observed under T 6 (weedy check).

“…Shortage of freshwater resources lead to the limits the production of the flooded / puddled rice crop in major rice producing countries like India and China (Shekara et al, 2011). To achieve the highest rice production with shrinking resources, research are necessary to increase rice yield with supply of less irrigation water (Murthy et al, 2012). Aerobic rice cultivation is not only a water-saving technique, but it also increases rice productivity (Kannan et al, 2015).…”

The scheduling of irrigation according to the ratio between irrigation water depth (IW) and cumulative pan evaporation (CPE) rate for aerobic rice. During these days, the shortage of water resources is increasing continually due to climate change. It has led to the adaptation of rice farming under aerobic conditions. This saves irrigation water, labour, eliminates puddling, reduces seepage, percolation losses, and methane emissions. Aerobic rice cultivars produce higher plant growth, physiological, root growth, yield, water use efficiency, productivity, and soil nutrient uptake under different (0.6, 0.8, 1.0, 1.2, 1.4, 1.5, 2, and 2.5) IW/ CPE ratios. Under these irrigation schedules, the yield of rice in aerobic soil is recorded at between 4.5 and 7.1 t ha-1 and the water use efficiency is from 25 to 70 kg ha-1. However, the decline in yield or even crop failure under continuous monocropping, weeds, nematode problems, and aerobic rice micronutrient deficiency Our important findings in aerobic rice are: (1) Scheduling of irrigation based on various IW/ CPE ratios recorded the higher rice plant height, number of tillers hill-1, dry matter production, leaf area index, crop growth rate, relative growth rate, root length, productive tillers, number of grains panicle-1, number of filled grain panicle-1, total number of grains panicle-1, test weight and yield; (2) The last 15 years of aerobic rice research findings focused on irrigation scheduling by IW/CPE ratio for driving economic water use; and (3) nutrient uptake increased with irrigation at more than 1.0 IW/CPE ratio with depth of 5 cm irrigation water. Declining water availability due to climate change makes it necessary to conduct more research on irrigation scheduling in rice crops in order to increase yield and water use efficiency.
