| Abstract | The study entitled “Standardization of crop establishment technique for uplandmrice (Oryza sativa L.) in coconut garden” was undertaken during 2017-2019 at College#of Agriculture, Vellayani, Thiruvananthapuram, Kerala with the objectives to find out the most cost effective crop establishment technique for upland rice and to assess its impact on#growth and#yield#of rice. The research work was carried out at Coconut Research Station, Balaramapuram. The variety used for the trial was Harsha (PTB 55). The crop was raised as an intercrop in 55 year old coconut garden planted at a spacingnof 7.6 m x 7.6 m. The fieldmexperimentmwas laid out in RBD with 10 treatmentsNin three replications during Kharif 2018 (May to September 2018). The treatments comprised of line sowing dry seeds 60 kg ha-1 (T1), line sowing hydroprimed seeds 60 kg ha-1 (T2), broadcasting dry seeds 80 kg ha-1(T3), broadcasting hydroprimed seeds 80 kg ha-1 (T4), broadcasting dry seeds 100 kg ha-1 (T5), broadcasting hydroprimed seeds 100 kg ha-1 (T6), broadcasting pregerminated seeds 80 kgha-1 (T7), broadcasting pregerminated seeds 100 kgha-1 (T8), thomba method of planting at 15 cm × 10 cm (T9) and thomba method of planting at 20 cm × 10 cm (T10). Organic manure 5 tha-1 and NPK 90:30:45 kgha-1 were given uniformly to all treatments. The results of the study revealed that the establishment techniques had significant influence on most of the growth characters, physiological parameters, weed absolute density, weed dry weight, yield attributing characters and yield of upland rice. Broadcasting hydroprimed seeds 100 kgha-1 (T6) producedmthe highestmnumber of hills m-2 at 20 days after sowing (DAS) which was on par with broadcasting hydroprimed seeds 80 kgha-1 (T4) and line sowing hydroprimed seeds 60 kgha-1 (T2). At 40 and 60 DAS, T4 and T6 produced higher number of tillers m-2 comparedmto othermtreatments. However, broadcasting hydroprimed seeds at 80 kg ha-1 (T4) recorded significantly higher number of tillers at harvest. Broadcasting hydroprimed seeds at 100 kg ha-1 recorded the highest LAI at 40 and 60 DAS, but it was on par with T2 ,T3, T4 ,T5 and T7 at 40 DAS and comparable with T2, T4 and T5 at 60 DAS. The root shoot ratio at 50 permcent flowering, was the highestx in T4, but was on par with T2 and T6. The DMP at#harvest#was the highest inT4, which was on par with T2 and T6. Total chlorophyll content at 40 DAS was higher in T6, comparable with T1, T2 and T4, while T4 recorded higher chlorophyll content at 60 DAS on par with T2, T3, T6 and T9. The CGR during 40 to 60 DAS was higher in T4, which was on par with T6 and T9, but during 60 DAS to harvest higher CGR observed in T4 was comparable with T2. Broadcasting hydroprimed seeds at 100 kg ha-1 (T6) recorded higher RGRduring 40 to 60 DAS and was on par with T4. At harvest, T4 recorded higher RGR, on par with all treatments except T3, T7, T9 and T10. The weed#dry#weight at 30 DAS was lower in all the treatments except T1, T7 and T10, while at 60 DAS, it was found lower in T4, comparable with T2, T6, T7 and T9. The period for 50 per cent flowering was the shortest in T2 (74 days) and was followed by T4 (78 days). Broadcasting hydroprimed seeds 80 kgha-1(T4) recorded higher values for yield attributes. However, it was on par with T1, T2, T5 and T9 for number of panicles per m2, with T6 for number of filled grains per panicle, and: T3 and T6 for panicle weight. The lowest sterility percentage recorded in T4 was on par with T2, T3 and T6. Line sowing dry/hydroprimed seeds 60 kg ha-1 each (T1 and T2); broadcasting dry/hydroprimed seeds 80 or 100 kg ha-1each (T3, T5, T4 and T6); broadcasting pre germinated seeds 80 kgha-1 (T8) as well as thomba method of planting at 15 cm × 10 cm (T9) were found comparable with respect to their effect on grain yield. Straw yield was the highest in broadcasting hydroprimed seeds 100 kg ha-1 (T6) and the lowest in thomba method of planting at 20 cm × 10 cm (T10). Line sowing hydroprimed seeds 60 kg ha-1 (T2); broadcasting dry/hydroprimed seeds 80 or 100 kg ha-1 each (T3, T5, T4 and T6) and broadcasting pre germinated seeds 80 kg ha-1 (T7) were found to be economical compared to other treatments. From the results, it can be concluded that broadcasting hydroprimed seeds 80 kg ha-1 (T4) with a grain yield of 3900.7 kg ha-1 and B: C ratio of 1.72 is the cost effective crop establishment technique for upland rice in coconut garden. |
