The research aimed to evaluate the onset of estrus, conception rate, pregnancy rate and duration of estrus in Bali cow, limousine cow and rambon cow after being administered with three different hormones to syncrhronize estrus. A randomized block design with two factors, type of cow and hormone dose, was performed. Fifty-four postpartum cows consisted of the three breeds were administered to a single dose of PGF2α (5 ml per cow), a double dose of PGF2α (10 ml per cow) and combination of PGF2α and hCG (1,500 IU per cow). An analysis of variance showed that different breeds did not associate with the hormone doses and their combination, as evident from the onset of estrus, duration of estrus, conception rates and service per conception. However, different cow breeds showed the same onset of estrus, service per conception and the different onset of estrus and pregnancy rates. On the other hand, different doses of PGF2α and its combination with hCG generated different onset of estrus, duration of estrus, and pregnancy rates, but shared common service per conception. In conclusion, Bali cow demonstrated a more appropriate fertility than Limousin cow and Rambon cow. A combination of PGF2α and hCG showed the most adequate hormonal treatment to synchronize the estrus compared to single and double doses of PGF2α.

Pola tanam sayuran secara tumpang sari telah dimanfaatkan secara meluas di sentra-sentra produksi  sayuran di Indonesia. Penelitian ini bertujuan mengetahui pengaruh pemupukan dan tumpangsari antara tomat dan kubis terhadap populasi Bemisia tabaci dan serangan penyakit virus kuning yang disebabkan oleh virus gemini pada tanaman tomat. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Sayuran, Lembang (1.250 dpl.) dari bulan Juni sampai dengan Oktober 2008. Rancangan yang digunakan ialah acak kelompok pola faktorial dengan empat ulangan. Dua faktor perlakuan yang diuji, yaitu (1) dosis pupuk (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha + K2O  145 kg /ha, serta  N 210 kg/ha + P2O5 183,125 kg/ha + K2O 181,25 kg/ha) dan (2) cara tanam (monokultur tomat dan tumpangsari tomat dengan kubis). Hasil penelitian menunjukkan bahwa penggunaan dosis pupuk yang tinggi dan tanaman tomat yang ditanam secara monokultur dapat meningkatkan populasi kutukebul dan serangan penyakit virus kuning dibandingkan dengan dosis pupuk yang lebih rendah. Penggunaan dosis pupuk yang tinggi tidak berpengaruh nyata terhadap peningkatan produksi tomat. Penggunaan dosis pupuk N 168 kg/ha + P2O5  146,5 kg/ha + K2O 145 kg/ha dan tumpangsari tomat dengan kubis dapat direkomendasikan sebagai komponen teknologi PHT untuk pengelolaan hama B. tabaci dan penyakit virus kuning pada tanaman tomat.<br /><br />The intercropping planting technique is widely implemented in vegetable production centers in Indonesia. The research on the application of different doses of fertilizers (N, P, and K) and the planting technique of tomato and cabbage  on B. tabaci and the yellow disease caused by gemini virus was carried out at the Indonesian  Vegetables Research Institute from June to October 2008. The objective was to determine the effect of different doses of fertilizers (N, P, and K) and tomato-cabbage intercropping on the population densities of B. tabaci and incidence of gemini virus on tomato.  A factorial randomized block design with two factors and four replication was used in the experiment. Two treatments factor were tested i.e.  (1) different doses of fertilizers (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha +  K2O 145 kg/ha, and  N 210 kg /ha +  P2O5 183,125 kg/ha + K2O 181,25 kg/ha), and (2) planting techniques (monoculture and tomato-cabbage intercropping). The result indicated that heigher doses of fertilizers resulted in higher population of whitefly per leaf and yellow virus symptoms on tomato compared to lower doses. Higher amounts of fertilizers did not significantly affect tomato yield. It is suggested that the dose of  N 168 kg/ha + P2O5 146,5 kg/ha + K2O 145 kg/ha, and the tomato-cabbage intercropping technique can be incorporated into the IPM program, especially for the management of  whitefly and gemini virus on tomato.<br /><br /><br />

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords:  Chili, Chromolaena odorata, compost  fertilizer, tanglefoot

Corn has great relevance for agribusiness as it is used in human and animal food, besides the energy matrix. The objective of this study was to assess the leaf content of macro and micronutrient, accumulation of primary macronutrients, production components and productivity with the application of pelleted organomineral fertilizer in different doses compared to mineral fertilization, in two soils of different textures in the corn crop. Two trials were conducted in the municipality of Uberl&acirc;ndia-MG-Brazil: one located near the highway BR 452 km 141, at the coordinate 18&deg;55&prime;26&Prime;S, 48&deg;09&prime;36&Prime;W, clay soil. The other at km 640 of BR 365, at coordinate 18&deg;54&prime;05&Prime;S, 48&deg;25&prime;20&Prime;W, sandy soil. A randomized block design with five replications was used, with five doses of organomineral fertilizer (40, 60, 80, 100 and 120% of the recommended dose of P2O5 for corn) and an additional with 100% of the recommendation of mineral P2O5, total of six treatments and 30 plots. The results showed that, with the exception of phosphorus leaf content, yield in the sandy texture and the number of grains per row in the clay texture, there was no difference between the doses of phosphate organomineral and did not differ from the mineral. Thus, phosphate organomineral is as efficient as mineral for phosphorus supply.

Hormonal treatment of cows at the coastal region of Barisal district of Bangladesh was performed to assess the improvement of pregnancy rate. A total of 100 cows and heifers with irregular history of cyclicity were selected randomly and divided into five treatment groups. The groups were A (treated with anthelmintic), B (treated with anthelmintic, vitamin ADE and multivitamin powder), C (treated with PGF2α), D (treated with GnRH) and E (treated with GnRH and PGF2α). Each group comprised of 20 animals. The age, breed and parity of experimental cows were considered during treatment. In the study, the cows treated with both GnRH and PGF2α (group E) showed significantly (p<0.05) higher estrus (80%) and pregnancy rate (60%) than that of group A, B, C and D. The overall estrus rates of local and crossbred cows were 64% and 70%, respectively and the pregnancy rates were 40 and 52%, respectively. The crossbred cows responded significantly (p<0.05) to hormonal treatment than that of local cows. Parity-2 cows showed higher estrus sign than that of other parities. However, the pregnancy rates were higher significantly (p<0.05) in parity-2 and parity ≥4 cows than that of parity-0, parity-1 and parity-3 cows. The pregnancy rate was also found higher in case of 4 to <5 years old cows than that of 2 to <3, 3 to <4, 5 to <6, and ≥6 years old. It may conclude that the hormonal regimen increases the pregnancy rate as well as decreases the undesired waiting of estrus and conception. Further study with more sample size will reveal the more effective treatment for cows at the coastal areas of Bangladesh.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice
