Abstract

Garam merupakan cekaman abiotik yang dapat menghambat pertumbuhan dan perkembangan tanaman melalui cekaman ionik, osmotik, dan ketidakseimbangan unsur hara. Penambahan hara silika berfungsi untuk meningkatkan ketahanan tanaman terhadap cekaman abiotik. Tujuan penelitian ini untuk mengkaji penambahan dosis hara silika padat terhadap pertumbuhan padi lokal aksesi Tasikmalaya pada kondisi salin. Penelitian ini dilaksanakan menggunakan Rancangan Acak Lengkap faktorial. Konsentrasi garam sebagai faktor ke-1 dengan 4 aras di antaranya 0 dS.m-1, 4 dS.m-1, 8 dS.m-1, dan 12 dS.m-1. Dosis hara silika padat sebagai faktor ke-2 dengan 3 aras di antaranya 300 mg.kg-1, 450 mg.kg-1, dan 600 mg.kg-1. Perlakuan konsentrasi garam berpengaruh nyata terhadap bobot kering tajuk 56 HST namun tidak berpengaruh nyata terhadap warna daun dan jumlah anakan 70 HST serta panjang akar dan bobot kering akar 56 HST. Konsentrasi garam 8 dS.m-1 menghasilkan bobot kering tajuk yang lebih rendah dibandingkan konsentrasi garam lainnya. Intraksi konsentrasi garam dengan dosis hara silika berpengaruh nyata terhadap tinggi tanaman dan bobot kering akar 56 HST. Konsentrasi garam 0 - 4 dS.m-1 dengan dosis silika sebesar 300 mg.kg-1 menghasilkan tanaman tertinggi, sedangkan konsentrasi garam 0, 4, dan 12 dS.m-1 dengan dosis silika 300 - 600 mg.kg-1 menghasilkan bobot kering akar tertinggi. Semakin tinggi konsentrasi garam maka akan menurunkan tinggi tanaman dan bobot kering tajuk, sedangkan konsentrasi garam 8 dS.m-1 ditambah dosis hara silika menyebabkan penurunan terhadap bobot kering akar, tinggi tanaman, dan bobot kering tajuk.

Abstract

Increased productivity of rice is required to meet the increasing food demand. Utilization of marginal lands, such as saline land is one of the solutions applicable to increase rice production. The objective of this study was to determine the growth and yield of Inpari 29 rice variety planted on raised-bed and different depths of sunken-bed in saline field. This study used the Split Plot Design with two treatments. The depth as the main plot consisted of two depth levels: a depth of 50 cm and a depth of 25; and the planting area field as the subplot that consisted of two levels: raised-bed and sunken-bed. The treatment was repeated three times. The rice planted in sunken-bed showed higher growth than in raised-bed as indicated by the high content of chlorophyll a, chlorophyll b, total chlorophyll, nitrate reductase activity and plant height. The rice planted in the sunken-bed yielded higher than in raised-bed as indicated by higher harvest index and the weight of grain per clump. Rice planted in 25 cm depth showed higher nitrate reductase activity and grain weight per clump than in 50 cm depth.

Abstract

Salinity makes disorder to plant physiological causes decreasing in biomass production. Applying silica nutrients is expected to increase paddy (Oryza sativa L.) tolerance to salinity. The study aims to examine the effects of the application of silica nutrients under saline conditions regarding plant growth analysis and its correlation to paddy biomass production. The research was arranged in a factorial completely randomized design with two factors. The first factor was NaCl concentrations consisting of four levels, including non-saline, 4 dS m-1, 8 dS m-1 and 12 dS m-1. The second factor was silica doses per kg soil with three levels including 300 mg, 450 mg and 600 mg. The treatments were repeated three times. The result showed that the NaCl concentration affected root shoot ratio at harvest. Silica dosage affected leaf area index 8 weeks after planting (WAP), root shoot ration at harvest and net assimilation rate. Interaction of NaCl concentration and silica dose affected root shoot ratio in 8 WAP and at harvest. Plant growth analysis illustrated on leaf area index, plant growth rate and root shoot ratio correlated positively with biomass production. However, the harvest index and net assimilation rate showed negative correlations to biomass production. The application of silica nutrients had the potential to improve paddy growth and yield under saline conditions.

Abstract

Introduction: Salinity is a major constraint in rice crop production through inhibiting the absorption of water and minerals. The seedling age optimally can increase the adaptability of plants under saline conditions. The objective of this study was to examine the agronomic, physiological, and biochemical responses of rice under saline conditions using the different seed age to determine their adaptability to the abiotic stress. Methods: The study used a CRD non-factorial, there is seedling age with three levels including 21, 28, and 35 days after sowing (DAS). The study used rice cv. Banyuasin and salinity stress given is NaCl with the concentration 8 dS m-1. The addition of NaCl when the plants were 12 and 54 days after planting (DAP). Results: The different seed age planted under saline conditions significantly affects to agronomic and physiological characteristics as indicated by shoot dry weight, plant biomass, and chlorophyll content. The different seed age planted under saline conditions significantly affects biochemical characteristics as indicated by proline content and nitrate reductase activity. The rice seedling age of 21 DAS produced the highest biomass and shoot dry weight, the rice seedling age of 28 DAS produced the highest chlorophyll content and nitrate reductase activity, and the rice seedling age of 35 DAS produced the highest proline content. Conclusion: The older rice seedling (35 DAS) increased the higher proline content, while the younger rice seedling (21 DAS) increased the shoot dry weight and plant biomass. In addition, rice seedlings (28 DAS) produced the highest chlorophyll content and nitrate reductase activity.
