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

Surjan system (alternating bed system) is an agricultural system that combines dry and wet bedding system. It integrates food crop culture in the sunken-bed and annual crops in the raised-bed of the rainfed rice field. In Bantul, farmers commonly apply Surjan system in rice field by growing shallot (Allium cepa L. aggregatum group) and chili (Capsicum annuum L.) in the raised-bed, whereas no crop is grown in the sunken-bed. This present experiment evaluated the utilization of the sunken-bed for rice cultivation by utilizing fertilizer runoff from the raised-bed. Rice plants in the sunken-bed were not fertilized due to the expectation that it could utilize the fertilizer runoff from the raised-bed. The cropping pattern and the fertilizer dose in the raised-bed are suspected to affect the growth and yield of rice in the sunken-bed. The purpose of this study was to determine the effect of cropping pattern and fertilizer dose applied in raised-bed on the growth and yield of rice in sunken-bed of the Surjan rice field. This study were laid out in a split plot design with three replication. The main plot consists of two cropping pattern, namely shallot monoculture and intercropping shallot with chili. The fertilizer dose applied in raised-bed, namely 100% farmer's habit; 50% farmer?s habit; and 25% farmers' habit, occupying the sub plot. Dose of fertilizer applied in riased- bed according to the farmer's habit in research locatin is 622 kg NPK/ha (16-16-16) ; 228 kg ZA/ha and 76 kg KCl/ha. The results showed that there was no interaction between the cropping pattern and the fertilizer dose applied in the raised-bed on the growth and yield of rice in the sunken-bed. Compared with shallot monoculture, intercropping shallot with chili in raised-bed decreased the growth of rice in the sunken-bed. Compared with the 100% fertilizer dosage of farmer's habits, the fertilizer dose of 50% of the farmer's habits in the raised-bed increased the growth of rice in the sunken-bed. Cropping pattern and fertilizer dose in the raised-bed did not significantly affect the rice yield grown in the sunken-bed of the Surjan rice field.

Abstract

It is expected that by utilizing marginal land (e.g. saline field) is able to increase rice production under saline condition. One of integrated approaches that can be applied is a raised- and sunken-bed system. This experiment aimed to investigate the growth and yield of rice under raised- and sunken-bed system as affected by saline irrigation. The field experiment was conducted at Baros Helmet, Bantul District, Yogyakarta from October 2016 to February 2017. The experiment was arranged in a multi-location (oversite) design, consisted of saline irrigation (S1) and nonsaline irrigation (S0) in a raised-bed (A1) and sunken-bed (A0) planting system. The observations were done on leaf area index, chlorophyll a, chlorophyll b, total chlorophyll, photosynthesis rate, total dry weight, root length, leaf Na+ and K+ concentration, proline concentration, maturity and dry grain yield (DGY). The results showed that saline irrigation negatively affected leaf area index, photosynthetic rate and root length of rice grown at sunken-bed. However, leaf Na+ concentration and leaf proline concentrations of rice grown at sunken-bed were higher. The leaf K+ concentration decreased with increasing Na+ concentration. Although saline irrigation could accelerate harvesting age of rice grown at sunken-bed, the dry grain yield of rice grown at sunken-bed did not significantly different with that of rice grown at raised-bed.

Abstract

Productivity of rice as staple food of Indonesia needs to be improved. One of the efforts is by utilizing saline area for agricultural land. Salinity can be a serious problem leading to a decrease in crop productivity. Plant adaptation under salinity is an alternative to lower the risk, which can be improved by seedling pretreatment. The experiment was conducted in Baros, Kretek, Bantul, Yogyakarta. The objective of this research was to determine the growth and yield response of rice cv. Dendang  to  the salt pretreatment at early stage. The experiment was arranged in completely randomized design. The treatments used were salt pretreatment (T1) and without salt pretreatment (T2). The salt pretreatment increased K+ concentration, total dry matter, plant height and number of tillers. However, it decreased proline and Na+ concentration of leaf. There was no significant difference on the yield and yield component. Increasing EC values up to 8.35 dSm-¹ at generative phase reduced the rice ability to cope this level of salinity despite the application of salt pretreatment. The benefit of salt pretreatment was exhibited on rice grown under EC value 5 dSm-¹.

Abstract

Salinitas merupakan salah satu faktor abiotik yang membatasi pertumbuhan dan produktivitas tanaman di seluruh dunia. Penyerapan Si oleh tanaman diketahui mampu mengurangi cekaman salinitas melalui perbaikan pada pertumbuhan dan hasil tanaman. Penelitian ini bertujuan untuk mempelajari pengaruh salinitas terhadap pertumbuhan dan hasil tanaman padi serta pengaruh penambahan silika terhadap pertumbuhan dan hasil tanaman padi tercekam salinitas. Penelitian ini dilaksanakan di rumah kaca, Fakultas Pertanian, Universitas Gadjah Mada pada bulan Juni-September 2017. Penelitian disusun dalam Rancangan Acak Kelompok Lengkap (RAKL) dengan 2 faktor dan 3 blok yang dijadikan sebagai ulangan. Faktor pertama yaitu tingkat cekaman salinitas akibat penambahan NaCl (N) yang terdiri atas tiga level yaitu air non salin (<0,4 dS/m), 4 dS/m, dan 8 dS/m. Faktor kedua adalah konsentrasi SiO2 (S) yang terdiri dari 0 mM, 1 mM, 2 mM, dan 3 mM. Hasil menunjukkan bahwa pada kondisi tanpa pemberian silika, tanaman padi tidak mampu bertahan terhadap cekaman salinitas dilihat dari penurunan gabah kering giling yang terjadi, sedangkan pada penambahan silika konsentrasi 1-2 mM menyebabkan tanaman mempertahankan hasil hingga salinitas 8 dS/m.

Abstract

The existence of genotype and environment (G x E) interaction causes difficulty in selecting suitable varieties of soybean in an agroforestry system based on kayu putih stands. This study aimed to determine the suitability of adaptive, stable and high yield soybean varieties in an agroforestry system based on kayu putih stands by using GGE-Biplot analysis. The experiment was conducted from May to August 2018 at Menggoran Forest Resort, Playen District, Gunung Kidul Regency, Special Region of Yogyakarta, Indonesia. The experiment was conducted using a randomized complete block design (RCBD) with five block as replications. The first factor was soil type in Menggoran Forest Resort, consisting of Lithic Haplusterts, Vertic Haplustalfs and Ustic Endoaquerts. The second factor was soybean varieties, consisting of Anjasmoro, Argomulyo, Burangrang, Dering I, Devon I, Gema and Grobogan. The observation was carried out on seed dry weight of soybean per hectare. The data were analyzed using Combined Analysis of Variance (ANOVA) with ? = 5% and GGE-Biplot. Dering I was the most suitable varieties in an agroforestry system based on kayu putih stands and showed the mean of highest yield of 1.22 tons ha-1.
