The purpose of this field verification was to determine the stability of yield of several drought-tolerant soybean genotypes selected from green house evaluation. The plants were planted at Muneng, Probolinggo in dry season (June-September 1995) with and without irrigation. From 5 tolerant genotypes, Mlg 2999 and Mlg 3474 gave a good stability of tolerance as evidence by less significance of growth and grain yield reduction. The tolerant genotypes of Mlg 2805 and Mlg 2984 suffered from tremendous leaves and pods abcission, leading to low yield.

PENGARUH JUMLAH AJIR DAN JUMLAH DAUN PADA AJIR TERHADAP PERTUMBUHAN TUNAS DAN SAAT MANJING PETIK PERTAMA PADA PEMANGKASAN AJIR TANAMAN TEH (Camellia sinensis L.) DI DATARAN TINGGI Ade Wachjar; , Supijatno; Riswan Basyri Nasution

The experiment was aimed to study the effect of number of lungs and leaves at lung to growth of shoots and first time harvest at lung pruning of height land tea (Camellia sinensis). The experiment carried out at Gedeh Tea Plantation, PTPN XII, Cianjur, West Java, from December 1993 to March 1994. In this case we used tea Clone TRI 2025. The experiment was arranged in Randomized Block Design with 3 replications. The first factor, number of lungs, consisted of 3 different level : 2, 3, 4 lungs per tea. The second factor, number of leaves at lung, consisted of 3 different levels : 25, 50, and 75 leaves per lung. The Experiment showed that number of shoots and first time harvest affected by number of lungs, but number of lungs didn't affect to height of shoot, percentage of banji, wet weight shoots on tipping and first pluck production were not affected. The tea with 4 lungs had significantly greater number of shoots than 2 or 3 lungs. The earliest first harvest time was achieved by 2 lungs tea (3 to 9 days earlier), but was significant with 3 lungs tea.

Two AI-tolerant genotypes (KB 44001 and Genjah Jepang) and two AI-sensitive genotypes of soybean (Kedelai Lumut and KB 46015) were subjected to Al concentration (1.50 mM Al with pH 4.0) in hydroculture for 3 weeks; the growth and their physiological responses were identified by measuring the changes of pH media, NO3ˉ /NH4+ uptake, ion absorption and organic acid content in the tissues. The result revealed that Al-tolerant genotypes soybean show a much better growth than the sensitive genotypes. Moreover, the tolerant genotypes showed the different responses to Al stress; they changed the pH media more significantly, accumulated less Al in the roots and accumulated more oxalate acid than the sensitive genotypes. Both the tolerant and sensitive genotypes had similar pattern n in N03ˉ /NH4+ uptake and other cation uptake. The results suggested that tolerance of soybean genotypes to Al toxicity is associated with their ability in the exclusion AI.

Water use efficient varieties in rice may have good opportunity in term of economic value and scarcity of water. This study was conducted to determine water consumption among rice genotypes that conventionally cultivated as low land (IR64, IPB97-F-15, Ciherang, Mentik Wangi, and Rokan hybrid), up land (Jatiluhur, Silugonggo), and amphibian type (Way Apo Buru, that could be planted both as lowland and up land). Rice seedlings at 14 days old were transplanted in a plastic container containing 83 kg of air dried soil, 1 plant per whole and 6 plants per container. The experiment was conducted in a vinyl house, using randomized complete block design with three replications. During rice growth, water table was maintained at 2 cm above soil surface, and water was added and recorded weekly. The results showed that varieties reveal production components and yield were different significantly. Water consumptions among varieties were significantly different, ranged from 15.93 L plant-1 for IR64 to 24.13 L plant-1 for Jatiluhur, or equal with 3,639 to 4,827 m3 ha-1. Jatiluhur was the most efficient variety in using water. This finding may guide us to explore benefit of water use efficient variety as sustainable option in water management of rice cultivation.
