Abstract
The aim of the experiment was to examine how wheat responded to extended period of high temperatures under controlled conditions to supplement field studies with these varieties on Lombok Island. Two Indonesian wheat varieties (Nias and Dewata) and two Australian varieties (Axe and Gladius) were examined in growth room experiments at 3 different temperature regimes 32/23°C, 28/20°C and 25/15°C day/night with 12 h daylight. Temperature and photoperiod were selected to simulate conditions on Lombok Island, at lowland (32/23°C) and highland (28/20°C) sites. A third temperature (25/15°C) was selected to represent temperature in a more temperate wheat producing area. The rate of plant development increases with high temperatures up to an optimum temperatures and slower after further increases. Despite being exposed to high temperatures from establishment, the effect of high temperature was more severe during the reproductive stage as seen by the fact that yield was more affected than dry matter accumulation and yield was most strongly related to grain number. Genetic variability in response to heat stress was evident with the Indonesian varieties being more tolerant to high temperatures than Australian varieties. Nias and Dewata produced higher yield and biomass.

Abstract
Abaca banana is one economic fiber plants,the lack of abaca banana supply has encourage the expansion of abaca banana plantation. To support the availability of plants material,propagation by tissue culture technique being a good alternative for mass production. This research was aimed at studying the responses of shoot production of abaca banana as result off effect of type of various charchoal and sucrose at MS medium through in vitro method. The study was conducted in the Laboratory Tissue Culture Department of Agrotechnology UPN”Veteran”Yogyakarta .Results showed that with addition of Norit 2 g/L and saccharose 30 g/L can significanly increase number of leaves, the lenght of planlet, the number of root and the length of roots.

Abstract
One of the strategic efforts to increase soybean production towards self-sufficiency with 2.8 million tons of production is through the expansion of suboptimal planting areas, among others, by using saline soil. The area of potential saline land in Indonesia is 140,300 ha. This study aims to determine the growth of several genotypes at a salinity soil level of 10 dS/m. This experiment was conducted using a randomized block design (RBD) repeated three times. The treatments tested were genotypes consisting of Deja 2, Dering, Karat 13, Panderman, Gepak Kuning, Daun Lancip, Dega1 and Tanggamus. Variables observed in this study include: plant height, root length, stover weight, root dry weight and soil salinity level at the age of 24 days, 45 days, 60 days and 75 days. All genotypes still live up to 45 days, but at 60 days after Dering, Tanggamus, Gepak kuning is dead, and only Daun Lancip can survive up to 75 days.

Abstract
Seeds were susceptible to drying injury in several ways i.e the delay time and the pile thickness of seed drying . The research was carried out to found the maximum delay time and the pile thickness to obtain the best seed viability and growth of rice using Innovated Drying Floor. This research was done from June to September 2019 at UPT Barongan Balai Benih Pertanian, Barongan, Sumber Agung Village, Bantul, Yogyakarta. The experiment was arranged on Split Plot design with two factors. The main plot was delay time of drying process: 2, 4 and 6 days. The subplot was the seed pile thickness: 3, 5, 7, and 9 cm. The treatments were repeated 3 times. Data were analyzed by analysis of variance 5% and test further with DMRT 5% (Duncan-s Multiple Range Test). The results showed that there was not interaction between the delay time and seed pile thickness on all parameters. The delay time of drying process: 2, 4 and 6 days and the seed pile thickness: 3, 5, 7, and 9 cm showed no significantly different on germination capacity and the growth of rice seed. The delay time of drying process until 6 days can be tolerated on the germination capacity and growth rice. The seed pile thickness until 9cm also can be tolerated on the germination capacity and growth rice.

Abstract
Herbicides was efficient but caused pollution of water sources, soil damage, and leave toxic residues in agricultural products. Environmentally friendly weed eradication can be done by using bioherbisida, such as Siam (C. odorata) leaf alelopathy. The research was conducted at Laboratory of Indonesian Legumes and Tuber Crops Research Institute (ILETRI) Malang in April 2017 using a complete randomized factorial design repeated three times. The first factors was: C. odorata extract concentration that consisted of: concentration 0% (w/v), concentration of 10% (w/v), concentration of 20% (w/v), concentration 30% (w/v). The second factor was the type of commodity that consisted of: soybeans, mungbeans and paddy. Making simplicia begins with the impregnation of fresh C. odorata leaves at 65 ˚C for 24 hours and then blended. 60, 40, 20 g of the simplicia soaked with 95% ethanol for four hours then each weight added aquades 200 ml and filtered with filter paper. Seeds was tested (arranged) on with CD paper which was wetted firstly with each extract C. odorata leaves concentrations and set aside. During the germination was doing, paper moisture was maintained by adding 10 ml of the extract C. odorata leaves of each concentration level. The observed variables were radical length (root), plumula length, and number of leaves at 4, 7 and 10 dap. The results showed that the leaves extract of C. odorata with concentration of 20% (w/v) and 30% (w/v) had potential as bioherbisida which could control weed growth.

Abstract
CVPD or greening disease is the most devastating disease on citrus production in Indonesia and in the world. It is vectored by Asian citrus psyllid (Diaphorina citri). Guava leave extract is a prospective control means for reducing psyllid population. Research was conducted to investigate the repellent effect of guava shoots to psyllids. Repellent effect of grinded dried upper shoot (leaf number 1 and 2 from the top) of 50oC and 80oC of red, white, and non-seed guava shoots to ten adult psyllids of mixed gender were determined in Y-tube olfactometer. Variation of proportion of guava leaf : citrus leaf (0:3; 1:1; 1:2; 2:1; 3:0) of guava shoots which have highest repellent effect also tested to the psyllids. The result shows that guava shoots has repellence effect to psyllids adult. The effect is reduced as the increase of drying temperature. Highest repellence effect is found from red guava shoots, followed by non-seed guava and white guava. Repellent effect of upper red guava shoots was 63.3%, 73.3%, and 76.7% on the proportion of 1:2, 1:1, and 2:1 respectively. It is suggested that the highest repellent properties is in red guava shoots and the ability will decrease in line with the increasing of drying temperature. The repellency is dose dependent. It increase with the increasing of guava leaf proportion.
