“…Similarly, providing drip fertigation with 100% normal fertilizers registered markedly higher uptakes of N (114.4 kg/ha), P (30.5 kg/ha) and K (67.2 kg/ha) over all the treatments in groundnut and showed 18.1, 16.9 per cent higher N and P uptake, respectively as compared to control ([100% normal fertilizers (NF) with surface irrigation) as reported by Jain et al [16]. This was in conformity with the results reported by Chandini et al [17], Sanju et al [18], Maurya et al [19]. Higher nutrient uptake in drip irrigation with fertigation was mainly due to application of controlled water near the crop root zone thus providing conditions for vigorous root development which helped in better water and nutrient uptake by the crop and higher root initiation with three equal splits caused significant differences in nutrient uptake pattern.…”

Aims: To study the nutrient uptake and status of available nutrients in soil after harvest of groundnut as affected by different irrigation levels and methods at Northern Transitional Zone of Karnataka. Study Design: The experiment was laid out in randomized block design with different irrigation levels and methods replicated thrice. Place and Duration of Study: AICRP on Groundnut, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during summer 2021. Methodology: We took 11 treatments involving different level and methods of irrigation using eight micro-sprinkler treatments, one drip fertigation treatment and two flood irrigation treatments. After harvesting soil nutrient status and nutrient uptake from the soil were analyzed. Results: Significantly higher total nitrogen, phosphorus and potassium uptake were recorded with drip irrigation applied at 0.6 ET0 at Seedling, 1.0 ET0 at Flowering, 1.25 ET0 at Pegging, 0.8 ET0 at Pod formation stages along with fertigation of N and P [3 splits at NF on 3rd, 4th and 5th week] and CaNO3 and S nutrients [3 splits at PGF on 7th, 8th and 9th week] (164.0, 27.6 and 129.3 kg ha-1, respectively) and was 40.0, 55.43 and 25.91 per cent higher compared to control (Flood FAO). Same treatment enhanced the soil chemical properties like pH, EC and organic carbon by 1.04, 16.12 and 7.40 per cent compared to control. Conclusion: Drip irrigation and fertigation enhanced nutrient uptake of groundnut and available soil nutrient status and also improved soil chemical properties as compared to control (Flood irrigation). So, this method can be proved beneficial in reducing the nutrient requirement of the crop under cultivation in the Northern Transitional Zone of Karnataka.

One of the main negative effects of climate change is the increasing scarcity of water worldwide. Wheat is the second major staple food of the world and drought is the main factor affecting its production. In order to ensure food security, there is need to adopt easy and economic techniques for increasing crop production under limited water resources. Two of the effective techniques are; use of ground covers and partial root zone drying (PRD). Experiments were comprised of two irrigation methods (I 1 = irrigation on both sides of roots and I 2 = irrigation to only one side of root as alternate irrigation) and four ground covers (M 0 = open ground without any cover, M 1 = black plastic cover, M 2 = wheat straw cover and M 4 = cotton sticks cover). Results revealed that more spike length, number of spikelets and grains were found in full irrigation treatment. While water use efficiency and grain nutrient (NPK) contents were more in PRD. All soil covers suppress the weeds and significantly influenced the yield attributes as well as the grain nutrient contents. However, black plastic cover performed the best. It was concluded that joint use of both techniques was more effective than their sole application and combination of PRD with black plastic mulch performed the best than rest of the treatments.
