“…Pratikshya recorded highest protein content of 6.63 % which was significantly higher from other varieties. The increase in protein content of rice grain may be due to a synergistic effect of P management on N uptake and its translocation in grains (Monica et al, 2020a). Similar observations were also found in case of amylose content in grains and it was found highest (20.36 %) with P 2 (100% of STD for P to both the crops) whereas lowest value (19.08 %) was recorded with P 4 (100% of STD for P of both the crops applied to green gram).…”

Field experiment was carried out during 2018 and 2019 in a rice-green gram cropping system to study the effect of phosphorus (P) management in kharif rice under acidic Alfisols of Odisha, India. The experiment was conducted in split-plot design with three replications. Four main plots viz., P1-100% of soil test dose (STD) for P as basal to rice, P2- 100% of STD for P to both the crops, P3-50 % of STD for P to rice and 100% of STD for P to green gram, P4 -100% of STD for P to both the crops applied to green gram were allotted to the main plots and three rice varieties viz., V1-Mandakini, V2-Lalat and V3- Pratikhya were considered in the sub plots. Application of 100% STD for P to both the crops (P2) resulted in the highest grain and straw yield (3981 and 4715 kg ha-1, respectively). Rice variety Pratikshya maturing in 145 days produced the highest grain and straw yields of 3808 and 4399 kg ha-1, respectively. The grain quality parameters of rice like protein content (6.75 %), amylose content (20.36 %) and alkali value (4.60) were found highest in P2 which was significantly different from other P management practices. Rice variety Pratikshya produced a better quality grain like protein (6.63 %), amylose (20.28 %) and alkali value (4.56). Significantly highest total chlorophyll content (4.61 mg g-1 fresh leaves) was also observed with P2 among the P management practices and a value of 4.46 mg g-1 fresh leaves chlorophyll content was recorded in rice variety Pratikhya. Microbial biomass carbon increased up to 30 days after transplanting (DAT) and decreased thereafter up to 45 DAT irrespective of phosphorus doses and rice varieties. The soil dehydrogenase activity was increased due to application of different doses of phosphorus and rice variety irrespective of growth stages. P uptake by rice was estimated highest with P2 (100% of STD for P to both the crops) and cv. Pratikhya responded better among the varieties.

Conventional fertilizers, although widely available, are relatively low in nutrient use efficiency and cause serious environmental concerns like eutrophication, greenhouse gas (GHG) emissions, nitrate poisoning, and soil pollution. With this in mind, a randomized block design (RBD) experiment was conducted in an experimental field taking 10 treatments and 3 replications to investigate the effects of integrated approaches of nano-formulated DAP fertilizer applications on rice growth, yield, and nutrient use efficiency over conventional approaches. The result revealed that plant height, panicle length, number of tillers hill−1, total number of grain panicle−1, and root length were maximum in T10 treatment (50% of the soil test recommended doses (STD) for N and P + seedling root dipping (SRD) with nano DAP at 5 mL L−1 + twice foliar sprays (FS) with nano DAP at 4 mL L−1 at 25 and 45 DAT (date after transplanting). The highest mean grain yields (4.12 and 4.05 Mg ha−1) and nutrient uptake were recorded in the T2 treatment (100% STD), but this was at par with T10 treatment. The highest benefit–cost ratio (2.26) was recorded in T10, which was 3.5% higher than T2. N and P agronomic use efficiency (AUE) ranged from 7.5% to 31.5% and 15% to 63%, and recovery efficiency (RE) ranged from 30% to 94.2% and 11.2% to 90.4%. The highest nutrient use efficiency was recorded with T10, followed by T9, and lowest in T4. Post-harvest soil pH and available N and P were significantly highest in T10. Soil MBC, MBN, MBP, urease, and phosphatase activity were found significantly higher in T2, followed by T10. The integrated application of 50% STD for N and P + SRD with nano DAP at 5 mL L-1 + twice FS with nano DAP at 4 mL L−1 at 25 and 45 DAT application can be a suitable substitute for conventional DAP and urea for rice in climate-smart agriculture as it possibly reduces environmental pollution while undisturbing crop yield over the 100% STD.

A field experiment was carried out in order to study the relative efficacy of different sources of sulphur in kharif rice (Cv. Swarna Sub 1) under mid-central table land zone of Odisha. It was carried out in RBD with 10 treatments and 3 replications. Four different sources of sulphur (Single Super Phosphate, Calcium Sulphate, Elemental S0 and Navaratna as (20-20-0-13) were used with two methods of application as basal & top dressing to rice crop during Kharif season. The treatment details consists as T1 = Control (No Sulphur), T2 = Basal application (B.A) of 30 kg S ha-1 through Calcium Sulphate (CaSO4), T3 = Basal application of 30 kg S ha-1 through Elemental S ( ES ) , T4 = Basal application of 30 kg S ha-1 (through SSP) , T5 = Basal application of 30 kg S ha-1 (through 20-20-0-13) , T6 = Twice application of 15 kg S ha-1 as basal and top dressing through CaSO4, T7= Twice application of 15 kg S ha-1 as Basal application & top dressing through ES , T8 = Twice application of 15 kg S ha-1 through SSP each at Basal application & top dressing, T9 = Twice application of 15 kg S ha-1 as Basal application and top dressing through (20-20-0-13) & T10 = Basal application of 30 kg S ha-1 through CaSO4 and SSP @1:1 ratio . Significantly highest pooled mean grain yield (5.41 t ha-1) and straw yield of (5.62 t ha-1) were recorded with T7, whereas the lowest values were recorded with (control) T1 (4.1 t ha-1 & 4.31 t ha-1 respectively). Among different sources of sulphur, the grain yield of rice varied significantly and it followed the trend as Elemental Sulphur (ES) > CaSO4 > SSP > (20-20-0-13). Spilt application of sulphur fertilizer showed a beneficial effect on S uptake and translocation of micronutrients like Fe, Mn, and Zn. The sulphur economic yield efficiency ratio also inversely varied with S applications.
