Abstract

The experiment was conducted on the Technical Irrigated Rice Field in D.I. Yogyakarta with soil type is Regosol. The study took place in July to December 2010. The research aim was to obtain agronomic characters and optimal planting distance that could increase the productivity of land with furrow irrigation system (FIS). The research used a factorial design (2 x 4+2) with 3 replications. Factor 1 was cultivars (K): K1 (Cimelati) and K2 (Sarinah). Factor 2 was planting distances (J): J1 (20 x 20 cm), J2(20 x 15 : 40 cm; legowo 2:1), J3(20 x 12,5 : 40 cm; legowo 2:1), and J4(20 x 12,5 : 45 cm; legowo 2:1). Controls were Cimelati and Sarinah cultivars grown in wetland rice field. The experimental results showed that the ability of plants to form seedlings in FIS was better than in the rice fields. The ability of plants to form seedlings in FIS at different planting distances was similar. Net assimilation rate (NAR) and relative growth rate (RGR) in the wetland system was better than FIS, but the leaf area index (LAI) and crop growth rate (CGR) was better in FIS. The NAR, RGR, and CGR in both systems were similar. Larger panicle and grain panicle number, 1000 grain weight and percentage of filled grain rice were found in FIS than in the rice field. The growth of rice in FIS was not affected by differences in both cultivars and planting distance. Dry harvested grain weight in FIS was lower than in the rice field. Dry harvested grain weight of Cimelati cultivar (8.04 t/ha) in FIS with planting distance of 20 x 12,5 : 40 cm (legowo 2:1) was comparable with that in the rice field (8.05 t/ha).

Abstract

Laju pembasahan dan tingkat pembasahan disamping bahan organik dipercaya mempengaruhi proses awal terjadinya koalesen agregat tanah yang dapat meningkatkan kekuatan tanah.  Penelitian ini dirancang untuk memisahkan kedua pengaruh itu sehingga dapat dilakukan perbaikan pengelolaan yang dapat dievaluasi dalam rangka meningkatkan efisiensinya yaitu apakah pengelolaan harus berfokus pada perbaikan teknik irigasi atau meningkatkan bahan organik, atau keduanya.  Polivinil alkohol (PVA) yang merupakan salah satu senyawa kimia yang dapat meningkatkan stabilitas agregat  diberikan secara terkontrol dengan menggunakan sprayer terhadap agregat tanah berdiameter 0,5-2 mm.  Sampel tanah bertekstur kasar dan halus ditempatkan dalam ring dan laju pembasahan air (1, 10 dan 100 mm/jam) menggunakan sistem tetesan yang dikontrol oleh pompa peristaltik.  Sampel tanah kemudian dibasahi hingga mendekati jenuh atau hisapan               10 kPa selama 24 jam, kemudian didrainase dengan menggunakan plat tekanan pada hisapan                100 kPa.  Pengukuran tahanan penetrometer diukur dengan menggunakan penetrometer kerucut berdiameter 2 mm, sedangkan kekuatan tarik diukur dengan alat uji tidak langsung Brazilian. Tahanan penetrometer lebih rendah pada sampel tanah yang mendapat perlakuan PVA sebelum pembasahan dan pada sampel tanah yang yang mendapat hisapan lebih tinggi (10 kPa) setelah pembasahan awal.  Pengaruh tersebut semakin menonjol pada tanah bertekstur kasar.  Pada kedua jenis tekstur tanah, kekuatan tarik meningkat dengan semakin tingginya laju pembasahan dan tingkat pembasahan (lebih besar pada kondisi hampir jenuh).  Laju pembasahan cenderung lebih penting dalam mendorong proses terjadinya koalesen agregat dari pada tingkat pembasahan

Abstract

The objective of this research was to study the effect of phosphorus (P) and calcium (Ca) fertilizers on productivity and nutrient uptake of two soybean genotypes under saturated soil culture.          The experimental design was a Split Split plot with three factors i.e. P fertilizer, Ca fertilizer and genotype planted under saturated soil culture. Saturated soil culture with P fertilizer (72 kg P­2O5 ha-1) and lime (1 ton ha-1) increased the number of pods and grain weight plot-1. Tanggamus variety had higher number of pods and grain weight per plot than Anjasmoro variety. Interaction of phosphorus fertilizer 72 kg P­2O5 ha-1 with lime 1 ton ha-1 increased grain weight plot-1. Largest direct effect on increasing grain weight is plant height and the number of branches. The application of P fertilizer (72 kg P­2O5 ha-1) and liming (1 ton ha-1) also gave highest uptake of P and Ca.  Saturated soil culture technology can be applied to increase soybean nutrient uptake and productivity. Key Words : Productivity, Soybean, saturated soil culture.

Abstract

This study aimed to findthe method that can determine the right amount of nitrogen need using either a conventional technique or a leaf color chart and to determine the rate of nitrogen better for rice plant growth and yield.  The study used a two factorial experimental design. Those factors were three rates of fertilizers and two kinds of fertilizer applications.  The rate of fertilizer needed by the plant was either 200 kg ha-1 as suggested by the leaf color method or 250 kg ha-1 as shown by the conventional method.  Based on the plant height and percent of empty grain, the leaf color chart method is better in determining the amount of nitrogen needed by the plant.  The addition of 250 kg ha-1 nitrogen tends to decrease the percent of empty grains. Keywords: Leaf color chart, Nitrogen, and Rice.
