To develop fertilizer prescription equations based on soil test crop response (STCR) approach for rice-rice cropping sequence, trials were conducted at farmer’s field in Karikalampakkam village, U.T. of Puducherry, during 2015-16. Soil test data, yield and nutrient uptake by successive crops were recorded to calculate four basic parameters viz. nutrient required to produce one quintal of rice, contribution of nutrients from fertilizers, contribution of nutrients from soil and contribution of nutrients from FYM used in developing STCR based fertilizer prescription equations. The per cent nutrient contribution of nutrients from soil (CS), fertilizer ( CF) and FYM (CFYM) were found to be 19.15, 45.90 and 23.27 for N, 12.13,40.16 and 26.98 for P2O5 and 13.76, 79.64 and 41.07 for K2O respectively for rice cv. White ponni. The same for the rice cv.ADT 45 were 13.48, 40.46 and 34.26 for N, 15.81, 44.64 and 19.89 for P2O5 and 10.48, 58.64 and 41.51 for K2O respectively. Based on fertilizer prescription equations and nomograms formulated for a range of soil test values and desired yield target for the cropping sequence. It was revealed that under the treatment NPK + FYM @ 12.5 t ha- 1 , 47, 29 and 34 kg ha- 1 for rice cv.White ponni and 41 , 22 and 27 kg ha- 1 for rice cv.ADT 45 of fertilizer N , P2O5 and K2O, respectively could be saved for attaining target yield of 70 q ha- 1 compared to NPK fertilizers alone.

Soil Test Crop Response (STCR) study was conducted during 2010-11 for autumn rice under integrated plant nutrition system (IPNS) in Inceptisols (Aeric Endoaquepts) in Jorhat district of Assam. The basic parameters were computed from the STCR data, and the fertilizer prescription equations were developed for recommending fertilizer doses in autumn rice. The nutrient requirement (NR) for producing one quintal of autumn rice was found to be 2.40 kg, 0.84 kg and 2.25 kg of N, P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O, respectively. The percent contribution of nutrients from soil (CS), fertilizer (CF) and FYM (CO) were calculated as 12.49, 45.31 and 32.92 for N, 13.42, 28.52 and 11.84 for P<sub>2</sub>O<sub>5</sub> and 21.99, 47.58 and 29.76 for K<sub>2</sub>O, respectively. These equations were validated in farmers’ fields during 2012 and the variation between actual yield and targeted yield ranged from +1.36 to +5.33.The fertilizer estimates under STCR-IPNS for 3000 and 4000 kg ha<sup>−1</sup> targeted yield recorded maximum response ratio and economic benefit in the field trial and confirmed the validity of proposed fertilizer prescription equations for autumn rice.

Effect of various levels of sulphur (50,100 and 150 kg ha-1) with three sources of sulphur fertilizers was studied on sugarcane crop in a field experiment conducted in Typic ustropept at Thiruppuvanam block of Sivagangai district during 2018-2019. The results revealed that the application of sulphur @ 100 kg ha-1 as FeSO4 as soil application along with application of N, P2O5 and K2O on Soil Test Crop Response (STCR) basis registered the maximum nutrient content of N, P, K & S in cane, leaf and total nutrient uptake. The cane yield (162 t ha-1) was maximum at the application of sulphur @ 100 kg ha-1 as FeSO4 followed by the treatment receiving 150 kg ha-1 of sulphur as FeSO4 inconjoint with N, P2O5 and K2O on STCR basis (157.00 t ha-1).

Studies on Soil Test Crop Response based Integrated Plant Nutrition System (STCR - IPNS) were conducted adopting the Inductive cum Targeted yield model onInceptisols (VerticHaplustepts) in Rahuri, District Ahemadnagar, Maharashtra, India in order to develop fertilizer prescriptions through IPNS for the desired yield targets of preseasonal sugarcane ratoon. The field experiments were carried out with maize as gradient crop for plant cane and after harvest of plant cane, pre-seasonal sugarcane ratoon as test crop. Using the data on yield, initial soil test values on available nitrogen (N), phosphorus (P), potassium (K), doses of fertilizers and farmyard manure (FYM) applied and NPK uptake, the basic parameters viz., nutrient requirement, contribution from soil, fertilizers and FYM were computed. It was found that 1.56 kg N, 0.58 kg P and 1.04 kg K were required for producing one tonnemillable cane of preseasonal ratoon sugarcane. The per cent contributions of N, P and K from soil and FYM for preseasonal sugarcane ratoon were 37.65, 85.88 and 19.82 per cent and 11.83, 10.88 and 12.24 per cent, respectively. Making use of these basic parameters, fertilizer prescription equations were developed for pre-seasonal sugarcane ratoon (var. C0-94012) and an estimate of fertilizer doses formulated for a range of soil test values and desired yield targets under NPK alone and IPNS (NPK plus FYM).

An insight into the balanced crop nutrition and efficient irrigation will be rewarding to attain profitable bulb yield of shallow-rooted and high nutrient requiring aggregatum onion. To develop fertilizer prescription equations(FPEs) for aggregatum onion under drip fertigation by encompassing the Soil Test Crop Response approach (STCR), a field experiment was conducted in Palaviduthi soil series with 15 treatments viz., Absolute control (T1), Blanket recommendation (60:60:30) + Farm Yard Manure (FYM) @ 12.5 t ha-1(T2), STCR based NPK fertilizer recommendation (STCR-NPK) for the targeted yield of 14 (T3),15 (T4),16 t ha-1 (T5), FYM @ 6.25 (T6), 12.5 t ha-1 (T7), STCR–NPK+FYM @ 12.5 t ha-1 for the targeted yield of 14 (T8),15 (T9),16 t ha-1 (T10), Biocompost @ 2.5 (T11), 5 t ha-1 (T12) and STCR–NPK+Biocompost @ 5 t ha-1 for the targeted yield of 14 (T13),15 (T14),16 t ha-1 (T15). The results revealed that T10 was more supercilious than others. The basic parameters were deliberated from the experimental data on total nutrient uptake, initial soil fertility status, applied fertilizer doses. The aggregatum onion (variety CO 4) required 0.43, 0.32, 0.45 Kg of N, P2O5, K2O to produce one quintal of bulb yield. The percent contribution of nutrients from soil and fertilizer was 14.01, 54.57 for N, 35.11,50.50 for P2O5 and 12.69, 70.12 for K2O, respectively. The contribution of N, P2O5, K2O from FYM and biocompost were 41.02, 16.23, 41.53 and 47.98, 15.87, 49.56 percent sequentially. Based on the above parameters, the fertilizer prescription equations were formulated for aggregatum onion under drip fertigation in Palaviduthi soil series.

Prairie producers are now being rewarded with significant premiums for producing wheat (Triticum aestivum L.) of high protein concentration. We analyzed data from two 12-yr experiments conducted on a medium-textured Orthic Brown Chernozem at Swift Current, Saskatchewan, to determine and quantify factors influencing grain N concentration of hard red spring wheat grown on stubble land. Results of one of the 12-yr studies, a snow management × fertilizer N, zero-tillage experiment, showed that under hot, dry conditions, grain N concentration was very high and increased with moderate rates of fertilizer N (FN), then levelled off at higher rates of N. Under cool, wet conditions, grain N first decreased (due to N dilution by yield) then increased with further addition of FN. Under warm intermediate moisture conditions, grain N concentration increased at moderate rates in response to FN. Data for the two 12-yr experiments were pooled and multiple regression, with backward elimination, and stepwise selection used to develop the relationship:Grain N (g kg−1) = −7.63 + 0.05 WU − 0.000094 WU2 + 0.30 SN − 0.0022 SN2 − (0.0010 SN × WU) + (0.0017 FN × SN) + 0.0189 DD (R2 = 0.64, P = 0.001, n = 262)where WU = water use (mm), SN = soil test N (kg ha−1), FN = (kg ha−1), and DD = degree-days >5 °C (°C-days) from 1 May to 31 August. WU was available spring soil water in 0- to 1.2-m depth plus 1 May to 31 July precipitation, and SN was NO3-N in the 0- to 0.6-m depth, measured in the fall. We attempted to validate this model using data from a long-term crop rotation and a fertilizer trial experiment in the Brown soil zone, a tillage × rotation experiment in the Dark Brown soil zone in Saskatchewan, and an irrigation × N fertilizer experiment in the Brown soil zone of southern Alberta. Validation met with only modest success (R2 up to 0.70, P = 0.001). Generally, estimated grain N concentrations were lower than the measured values. Water use (negatively related) and temperature (DD) (positively related) were the most important factors influencing grain N, while FN and SN (positively related) were much less important. Because of the complexity of response in grain N to the aforementioned factors, and since farmers cannot predict weather conditions, fertilizer management to achieve high protein remains a challenge under dryland conditions. Key words: Soil test N, fertilizer N, available water, degree-days
