“…The recommended dose of fertilizer (RDF) at 25: 50: 75 kg NPK ha -1 was applied. Drip and micro sprinkler irrigation was scheduled based on daily pan evaporation (PE) and fertigation on the basis of nutrient uptake pattern at different growth stage of groundnut as suggested by Loganathan and Krishnamoorthy (1977), at once in three days interval and the volume of irrigation water was calculated by using following formula: Volume of irrigation (V) = 3 days CPE × Kp × Kc × Area(m 2 ) × Wp -ER Where, CPE -Cumulative pan evaporation for three days (mm); Kp -Pan factor (0.8); Kc -Crop coefficient; Wp -Wetted percentage (80%) for drip; 100% for micro sprinkler (As over lapping was 100%); Area -28.8 m 2 ; ER -Effective rainfall…”

A field investigation was carried out in farmer's field at Pudhupalayam, TNAU, Coimbatore, during 2015, to improve the productivity of groundnut variety TMV 13 under drip and micro sprinkler fertigation system. The experiment was laid out in randomized block design (RBD) with three replications comprising of 11 treatments. Results indicated that maximum pod yield (3495 kg ha -1 ), haulm yield (6452 kg ha -1 ), harvest index (0.351) and shelling per cent (73.95 per cent) were obtained with drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T 1 ). The water saving achieved under drip irrigation was 40.08% and 55.06% at 100% and 75% PE, respectively, whereas, under micro-sprinkler, it was 25.10% and 43.83% at 100% and 75% PE, respectively over surface irrigation. Higher WUE of 19.28 kg/ha-mm recorded under drip irrigation at 75% PE with fertigation at 100% RDF as WSF (T 2 ) followed by drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T 1 : 15.88 kg/ha-mm). Highest NUE (23.30 kg kg -1 NPK ha -1 ) was recorded in drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T 1 ). Drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T 1 ) recorded higher gross return (Rs. 254353 ha -1 ) and net return (Rs.134712 ha -1 ). Whereas, the benefit cost ratio was highest in micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T 6 : 2.41). The margin benefit cost ratio (MBCR) was recorded highest under micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T 6 : 2.53) as compared to all other treatments.

“…The requirement of S for groundnut is very important at early growth stage (15 to 25 days) (Meena et al 2007) while Ca is essential during peg initiation, fruit formation and pod maturation stages (Kabir et al 2013). Groundnut plant uptake is 40 to 50% of their required nutrients between vegetative and reproductive stages (Loganathan and Krishnamoorthy 1977). Further, Ca and S requirements are mainly taken up by the pod from the soil, and adequate supply of these nutrients in the pegging zone is critical for the production of quality kernel (Zharare 1996).…”

Slag-based gypsum (SBG) is a unique synthetic gypsum which is alkaline in nature, besides calcium (Ca) and sulphur (S); it contains appreciable amounts of iron (Fe), silicon (Si), phosphorus (P) and zinc (Zn). In this study, we evaluated the efficacy of SBG as a source of S, Ca and Si for groundnut in comparison with natural gypsum (NG). The effect of different levels and time of application of SBG on soil fertility and yield and quality of groundnut were also studied. Field experiments were conducted with five treatments which includes two levels of SBG (500 and 625 kg ha −1) applied as basal and basal + split and one level of NG (500 kg ha −1) applied as basal. Basal and basal + split applications of SBG significantly increased the pod and haulm yield of groundnut, pH, electrical conductivity and plant-available nutrients in post-harvest soil. However, N:S ratio, kernel and protein yield and oil content did not vary with SBG application. Applied S, Ca and Si as SBG and their uptake were positively correlated with plant-available S, Ca and Si and pod, oil and protein yield of groundnut, respectively. Basal and basal + split applications of SBG resulted in a similar effect on soil fertility and yield and quality of groundnut. Findings from this study show that SBG can be a potential alternative for NG as a source of S, Ca and Si for groundnut production. Among the treatments, basal and basal + split applications of 625 kg SBG ha −1 substantially improved the fertility of soils and yield and quality of groundnut.
