“…Similar findings also reported by Shreenivas et al (2017) [17] that pooled results registered significantly higher grain yield of maize with treatment receiving SSNM approach targeted yield of 8.0t ha -1 . These results are also coroborated with the findings of Doberman et al (2002) [7] , Biradar et al (2006) [4] , Umesh et al (2014) [20] and Singh et al (2014) [19] . However, it was found on par with treatments of T 7 :SSNM approach targeted yield of 30q ha -1 (2534 and 4868kg ha -1 ), T 11 : STCR approach targeted yield of 30q ha -1 +25kg ha -1 FeSO 4 5H 2 O (2397 and 5083kg ha -1 ) and T 12 : SSNM approach targeted yield of 25q ha -1 +25kg ha -1 FeSO 4 5H 2 O (2382 and 4968kg ha -1 ) and significantly superior over T 2 :RDF (2015 and 4183kg ha -1 ), T 3 : STL method (2144 and 4430kg ha -1 ), T 4 : STCR approach targeted yield of 25q ha -1 (2150 and 4592kg ha -1 ), T 5 : STCR approach targeted yield of 30q ha -1 (2300 and 4697kg ha -1 ), T 6 :SSNM approach targeted yield of 25q ha -1 (2278 and 4635kg ha -1 ), T 8 :RDF +25kg ha -1 FeSO 4 5H 2 O (2168 and 4462kg ha -1 ), T 9 :STL +25kg ha -1 FeSO 4 5H 2 O (2244 and 4567kg ha -1 ) T 10 : STCR approach targeted yield of 25q ha -1 +25kg ha -1 FeSO 4 5H 2 O(2295 and 4787kg ha -1 ), The lowest seed and haulm yield was recorded in absolute control (1024q ha -1 and 3298kg ha -1 ).…”

The improvement in seed yield characters was the manifestation of improved growth characters as a result of higher uptake of nutrients caused by balanced supply of nutrients in this regard soil test based nutrient management approaches aims provide a scientific basis for balanced fertilization to obtain more yield per unit of fertilizer investment. An experiment was conducted during kharif and rabi seasons of 2017-18 and 2018-19 at Agricultural Research Station, Janwada, Bidar district, which comes under the jurisdiction of University of Agricultural Sciences, Raichur, to study the soil test based nutrient management approaches on seed yield and nutrient uptake of soybean-sorghum cropping sequence. Pooled results indicate that maximum seed yield (27.82q ha -1 ) was recorded with application of nutrients as per SSNM approach for targeted yield of 30q ha -1 +25kg FeSO4 5H2O ha -1 in soybean. Similarly maximum sorghum grain yield (1210kg ha -1 ) was recorded with the residual effect of nutrients through SSNM approach for targeted yield of 30q ha -1 +25kg FeSO4 5H2O ha -1 and higher uptake of nutrients (seed +haulm) viz., nitrogen (231.99kg ha -1 ), phosphorus (17.17kg ha -1 ), potassium (90.04kg ha -1 ) sulphur (55.82kg ha -1 ), zinc (159.36g ha -1 ), iron (3035.2g ha -1 ), and), boron (75.88g ha -1 ) by soybean. Similarly higher uptake of nutrients (grain +stover) viz., nitrogen (22.83kg ha -1 ), phosphorus (9.64kg ha -1 ), potassium (29.43kg ha -1 ), sulphur (2.68kg ha -1 ), zinc (49.70g ha -1 ),), iron (121.04g ha -1 ), and), boron (20.98g ha -1 ) by sorghum was recorded with residual effect of nutrients through SSNM approach targeted yield of 30q ha -1 +25kg FeSO4 5H2O ha -1 as compared to absolute control, RDF, and other soil test methods.

“…The number of pods per plant was significantly influenced by zinc application and soil application of Zn @ 5 kg ha -1 at the time of sowing (Z1) recorded significantly highest number of pods per plant (140.48) followed by two foliar spraying of ZnSO4 @ 0.5% at branching and flowering stage (Z2) (129.55) and lowest in control (Z0) is (118.91). The findings of present investigation correspond with the results quoted by Umesh et al (2014) [15] , Pandey et al (2014) [5] and Praveena et al (2018) [7] the result revealed that the yield attributes viz., number of pods per plant recorded significantly higher in treatment of 20 and 35 DAS (0.2% foliar spray) of boron + 5.0 kg ha -1 of zinc.…”

“…Considering the fertilizer cost and availability, this limited resource needs to be saved for sustainable crop production through improving the nutrient use efficiency by site specific application. Site specific nutrient management (SSNM) is a set of scientific principles for optimally supplying essential nutrients to achieve targeted yield (Umesh et al, 2014). We need SSNM mainly for increasing nutrient use efficiency and profitability.…”

A field experiment was conducted at the Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore, to know the effect of site specific nutrient management (SSNM) on growth and yield of groundnut. The fertilizers were applied to the crop based on uptake pattern, target yield and soil fertility status. The study indicated that application of fertilizers based on SSNM for target yield of 2.5 t ha-1 + S (10 kg ha-1) + B (10 kg ha-1) + Zn (12.50 kg ha-1) recorded significantly higher growth parameters viz., plant height (45.3 cm), number of branches (8.10), leaf area (814.95 cm-2), leaf area index (2.72) and total dry matter accumulation (31.82 g plant-1). The yield parameters viz., total number of pods per plant (19.57), pod weight per plant (12.05 g), 100 kernel weight (34.74 g) and shelling per cent (75.32) were significantly higher with the application of fertilizers based on SSNM for target yield of 2.5 t ha-1 + S + B + Zn compared to recommended dose of fertilizer. The Maximum gross returns were obtained in T4 (application of SSNM for target yield of 2.5 t ha-1 + S + B + Zn) (Rs. 79219), where as, higher net returns and B:C ratio were obtained with T3 (SSNM for target yield of 2.5 t ha-1) (Rs. 46771 and 2.47 respectively) and lower net returns and B:C ratio were with application of Rec. NPK + FYM (T1) (Rs. 33852 and 2.13 respectively).
