The experiment was conducted in rabi season during the year 2007-08 at Horticultural Research Farm, I.G.K.V., Raipur (C.G.)m India. There were 25 treatment combinations involving 5 irrigation levels (Furrow irrigation at 1.2 IW/CPE, drip irrigation at 100, 80, 60 & 40 per cent PE) and 5 nitrogen levels (50, 75, 100, 125 & 150 per cent of recommended dose of fertilizer) through fertigation. Results indicate that all the growth parameters (plant height and number of leaves) were significantly influenced by irrigation and fertigation with nitrogen levels. Higher plant height and more number of leaves plant-1 were observed with drip irrigation at 100 per cent PE and fertigation applied @ 150 per cent of recommended dose of nitrogen. Increasing the irrigation and nitrogen levels increased the yield significantly and highest yield (30.60 ton ha-1) was obtained with drip irrigation at 100 per cent PE and fertigation with 150 per cent of recommended dose of nitrogen (29.71 ton ha-1).

An investigation was carried out to examine the effect of irrigation and fertigation levels on nutrient uptake by cabbage. Cabbage (Brassica oleracea var. capitata) being a high yielding & a highly nutrient responsive crop requires large dose of nutrients. Drip irrigation and fertigation is a better way for maximizing its production through efficient use of irrigation water and applied nutrients. Total uptake of nitrogen (287.93 kg ha-1), phosphorus (25.30 kg ha-1) and potassium (297.11 kg ha-1) were maximum at drip irrigation at 100 per cent PE. Similarly, the maximum uptake of nitrogen (296.22 kg ha-1), phosphorus (26.90 kg ha -1) and potassium (309.74 kg ha-1) were observed at fertigation with 150 per cent of recommended dose of nitrogen.

The experiment was carried out during kharif season of 2012-13 at the farm, Krishi Vigyan Kendra, Lakhanpur village, Katghora block, Korba district (Chhattisgarh). The experiment was laid out with 63 rice genotypes and 5 check varieties in augmented design. The soil was highly acidic in reaction and low in available macronutrients. Available Fe, Mn and Cu were above the critical levels, while the Zn was below the critical level. Among the genotypes Denteshwari in early, IR 64 in mid early, Indira Maheshwari in medium, Safri-17 in late durations and Mahisugandha in aromatic groups produced higher yield and nutrient uptake compare to other genotypes which made them acid tolerant. The uptake pattern of macronutrients followed the similar trend of yield in these genotypes. Copyright © EM International.


Results revealed that the leaf powder of goat weed (Ageratum conyzoids) @ 2.5g/50g of seeds was the most effective against the egg laying of C.maculatus as minimum number of eggs (1.2) while aak (Callotropis gigantia) leaf powder @ 2.5g/50g of seeds and bathua (Chenopodium album) leaf powder at same dose were least effective. A. conyzoids also showed least percentage of egg hatchability (0.51%). The remaining treatments were moderately effective.
