Phosphorus (P) is an essential plant macronutrient that is commonly applied as a fertilizer for optimal crop production. As the global supply of fertilizer-P sources, mainly derived from mined rock phosphate (RP), is decreasing, alternative nutrient sources need to be developed and tested, such a wastewater-recovered struvite-P materials. The objective of this greenhouse study was to evaluate below-and aboveground rice ( Oryza sativa ) response to various fertilizer-P sources [ i.e., mono-and diammonium phosphate (MAP and DAP, respectively), triple superphosphate (TSP), RP, electrochemically and chemically precipitated struvite (ECST and CPST, respectively), and an unamended control (UC) ] under flood-irrigation in a P-deficient, silt-loam soil. Of the 17 belowground properties evaluated, eight differed ( P < 0.05) among fertilizer-P sources, while three were at least numerically largest from CPST. Of the 17 aboveground properties evaluated, six differed ( P < 0.05) among fertilizer-P sources and all six were at least numerically largest from MAP or DAP. For all 22 rice properties that differed ( P < 0.05) among fertilizer-P-sources, either ECST, CPST, or both had a similar response to TSP, DAP, and/or MAP, while belowground P and calcium (Ca) and grain potassium (K) concentrations from CPST were greater ( P < 0.05) than from TSP, DAP, or MAP. Results demonstrated that struvite-P sources (i.e., ECST and CPST) are a viable, alternative fertilizer-P source, as evidenced by the large frequency of similar rice responses to other commercially available fertilizer-P sources commonly used for flood-irrigated rice production on a silt-loam soil in Arkansas (i.e., TSP, DAP, or MAP).

Rice is the life and livelihood of Indians and the fact is more appropriate to the eastern part of the country. Rainfed and drought prone upland rice contributes a significant part of the total rice cultivation not only in India but also at the global level. However, the productivity is very low as compared to other rice-ecosystems. Hybrids were released from many institutions having several advantages and limitations. Comparative evaluation of rice hybrids and high yielding varieties (HYVs) under transplanting and direct seeding conditions is necessary to obtain a comparative picture. A field trial was conducted for three consecutive years to compare HYVs and popular hybrids under integrated crop management in drought prone rainfed ecology. Results of the experiment revealed that higher number of tillers were noted under wet-direct seeding, whereas increased application of fertilizer dose did not influence tillering under both direct seeding (DSR) and transplanting methods of crop establishment. Number of panicles per unit area also showed similar trend as tiller number and it was found that number of panicles were more in DSR as compared to transplanted rice. Grain yield between the transplanted and DSR is comparable, however, reduction in yield was higher in case of hybrids when switched from transplanted to DSR as compared to HYVs. Hence, it can be concluded that, in the drought prone rainfed areas HYVs should be preferred for cultivation over hybrids under DSR as there is diminishing scope of transplanted rice cultivation.

In the present investigation, laboratory and field screening of nine rice genotypes, namely, TM 12061, TM 12077, TM 12012, TM 14035, TM 16017, Senthuram, Vandhana, TKM 12 and Anna (R) 4 was taken up to assess their drought tolerance potential. For laboratory screening, the effect of different levels of PEG concentration namely, -0.2, -0.4, -0.6 and -1.0 MPa on germination, shoot length and root length were studied. There was a considerable decrease in the germination potential among all the genotypes with increase in PEG concentration. The culture, TM 12077 showed higher level of tolerance to PEG induced drought stress showing 30.8% germination with 3.2 cm and 8.85 cm shoot and root length, respectively at higher level of PEG concentration (1.0 MPa). In field screening under managed stress condition, the cultures, TM 12077 and TM 12012 showed higher accumulation of proline (4.15 mg/g). Chlorophyll stability index was more than 80% in the genotypes, TM 12012, TM 12077, and TM 12061. The culture TM 14035, the varieties Anna (R) 4 and Vandhana matured early in 115 days. Plant height was found to be moderate in Vandhana (103.3 cm), TM 12077(105.4 cm), TM 12061 (108.2 cm) and TM 12012 (110.5 cm) under managed stress condition. The number of tillers per plant, number of panicles/sqm and yield/hectare were maximum in the culture, TM 12077 under managed stress condition. Based on laboratory and field screening, the cultures TM 12077, TM 12012, and TM 12061 were found promising for water stress environment and can be utilized as donors in the breeding programs for drought tolerance in rice. High heritability coupled with moderate to high GA as per cent of mean was recorded for plant height, tillers per plant, chlorophyll Stability index and total chlorophyll content indicating the presence of additive gene effects and scope for their improvement through direct selection.

A field experiment was conducted during the kharif (2013) at Tamil Nadu Rice Research Institute (TRRI), Aduthurai to evaluate the productivity and input usage of different rice establishment methods viz., wet direct seeding using drum seeder, dry direct seeding using tractor operated seed drill, and conventional transplanting. Data reveal that dry seeding using a tractor drawn seed drill utilized a lower seed rate of 30 kg/ha compared to wet seeding (37.5 kg/ha) and transplanted rice (60 kg/ha). The plant height and plant population did not exhibit significant variations across the different establishment methods. However, yield attributes like ear bearing tillers (396/m2 ) and filled grains (137/panicle) were significantly higher in transplanted rice. Nonetheless, dry seeded rice recorded a grain yield of 6040 kg/ha which was only 5.5% lower than that of transplanted rice. Notably, dry seeding conserved 32.6% of irrigation water and reduced labour requirement by 48.9% compared to transplanted rice. Moreover, dry seeded rice exhibited higher water productivity (6.40 kg/ha/mm) and a higher benefit cost ratio (2.66) as compared to other establishment methods. Therefore, considering the existing water crisis and labour shortage, the adoption of dry seeding for rice cultivation holds promise as a viable solution for farmers. This method not only addresses the challenges posed by limited water availability and the scarcity of labour but also maintains satisfactory levels of productivity

The experiment was carried out to evaluate the genetic variability, heritability and genetic advance in rice under the sodic soil condition. Results revealed highly significant variations within parents and hybrids. The five characters viz., number of spikelet’s per panicle, grain per panicle, amylose content, flag leaf area and 1000-grain weight showed high estimates of heritability coupled with high estimates of genetic advance as well as less than one average degree of dominance and predictability ratio nearly one in F1 ’s. This indicated that the inheritance of these five characters was governed by additive gene action and the direct selection for these characters would be rewarding
