Abstract

A study was conducted to study correlation between some characters of upland rice and path coefficient analysis, which will be helpful for further selection process to improve upland rice in acid soils. The results of evaluation of lines for Al-tolerant in acid soils revealed that number of tillers and filled grain per panicle were inherited with high heritability and directly affected grain weight and contributed indirectly to the correlation between grain weight and other characters. However, indirect selection through number of tillers and filled grain per panicle was less efficient than direct selection through grain weight.

Abstract

            The purpose of this study was to investigate effect of storage period length under low temperature on host preference and host suitability for egg parasitoid, Trichogrammatoidea armigera.  In this study, Corcyra cephalonica eggs were used as the alternative host.  The result showed that the storage of host eggs under low temperature for 1.5 to 3 hours was able to delay host egg hatching until the day 5, however, for normal host eggs the hatching time was started at day 4.  This method did not exert a negative effect on host preference and host suitability for parasitoid T. armigera.  The rate of parasitism on the stored hosts was more than 90%, and it was not significantly different from the normal host.  T. armigera progeny (offspring) emerged from the stored host was also very high (more than 100%).  The result also showed that the percentage of T. armigera female progeny emerged from stored hosts higher than the normal host.  The female progeny emerged from normal host was 51%, while from hosts stored under low temperature for 1.5, 2.0, 2.5 and 3 hours were 69,49%, 66,03%, 66,16% and 71,10%, respectively.  The results indicated that the stored host eggs under low temperature (1– 4 oC) for 1,5 – 3,0 hours did not kill the host embryo, but only delay the hatching times.  Therefore, the availability of a sufficient number of fresh hosts could be maintained in the laboratory, so that the efficiency of mass rearing program of T. armigera parasitoid could be increased.

Abstract

            The study on application of different dosages of paraquat herbicide on different ages of milkyweed (Calotropis gigantea R. Br) have been conducted in Experimental Station, Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh. The treatments were arranged in a Completely Randomized Design (CDR) with two factors. The first factor was dosages of herbicide which were 0; 0,1; 0,2; 0,3; and 0,4 kg active ingredient (a.i.) ha-1. The second factor was ages of  C. gigantea R. Br which were 30 days, 45 days and 60 days after planting. The result showed that dosage of 0,3 kg i.a. ha-1 significantly increased the percentage of C. gigantea R. Br and decreased the dry weight shoot and root of C. gigantea R. Br. The youngest stage of C. gigantea R. Br was more effective to be controlled, and had a lower dry weight shoot and root than the oldest one. The paraquat herbicides applied with dosages of 0,3 kg a.i. ha-1 on 30 days after planting increased the percentage of C. gigantea R. Br, and  reduced shoot and root dry weight of C. gigantea R. Br.

Abstract

The objectives of this research were to find out dosages of biofertilizer and manure which was the most effective to control bean fly (A. phaseoli). This research was carried out at Cot Cut Village, District of Kuta Baro, Aceh Besar, from September to December 2008. This research used a factorial randomized complete block design with two factors: biofertilizer (H) and manure (K).  Dosages of biofertilizer were H1= 2,8 L ha-1, H2= 3,5 L ha-1, H3= 4,2 L ha-1, and H4= 4,9 L ha-1. Dosages of manure fertilizer were K1= 2,8 ton ha-1,  K2= 5,6 ton ha-1 and K3= 8,4 ton ha-1.  The result showed that application of biofertilizer was more effective than that of manure fertilizer to percentage rates of the attacked plant. However, both biofertilizer and mature fertilizer exerted  significant effects to percentage of plant death, plant dwarf, number of larva and pupa, and dry seed weight per plant.  Application of biofertilizer at 4,9 L ha-1 and manure fertilizer at 8,4 ton ha-1 reduced  percentages of  plant death up to 86% and 83%, respectively.

Abstract

           The objective of this research was to study content of heavy metal  (Pb) in soil and lettuce tissue caused by organic and inorganic fertilizers application. This research applied a factorial completely randomized design (CRD) with 3 replicates. The first factor was organic fertilizer, consisting of 4 levels and the second factor was inorganic fertilizers, consisting of 2 levels. Variables observed were fresh weight, and content of heavy metal in soil and tissue. Results showed that application of organic and inorganic fertilizers could reduce level of lead Pb) in soil and plant tissue. The highest Pb concentration was in the treatment without organic fertilizer and the lowest Pb concentration was in the organic fertilizer of 45 tons per ha, which was not significantly different from the organic fertilizer of 30 tons per ha. The highest plant fresh weight was obtained in dosage of organic fertilizer 15 tons/ha in the second planting. The best combination for plant fresh weight was an organic fertilizer of 15 tons/ha and an inorganic fertilizer of 1000 kg/ha.

Abstract

            The objective of the research was to find out a suitable bulb slicing and kind of organic fertilizer for a maximum growth and yield of onion.  This research applied a randomized complete block design (RCBD), 3 by 3 with 3 replications. Factors observed were bulb slicing and kinds of organic fertilizer.  Bulb slicing consisted of no cut, cut of one-third, and cut of one-fourth of onion bulbs.  Organic fertilizer consisted of compost, manure of cow and manure of chicken. Variables observed were plant height, a number of onion tillers per bunch, a number of onion bulbs per bunch, wet and dry weight of bulbs per bunch.  Result showed that bulb slicing significantly affected a number of onion tillers per bunch at 30 day after planting (DAP), 45 DAP, and a number of onion bulbs per bunch. However, bulb slicing did not significantly affect plant height at 15 DAP and dry weight of bulb per bunch.  The best growth and yield was found at cut of one-fourth of the bulb. Organic fertilizer showed a significant effect on a number of bulbs per bunch but did not exert a significant effect on other variables. More bulbs per bunch were achieved at compost. There was no significant interaction between bulb slicing and organic fertilizer type on growth and yield of onion.
