Pokem (Pennisetum�americanum L.) is a crop that has high content of carbohydrate. It grows widely at Numfor Biak of Papua. This crop could be an alternative staple food in order to enhance food security through food diversification program. The objective of the research was to examine the influence of chicken manure on the growth and yield of pokem. The research was done at Kebun Percobaan Fapertek UNIPA Manokwari for three months from October to December 2009. It used random plot design with four level treatments of chicken manure dose; they are 0 g/crop (N1), 250 g/crop, 375 g/crop (N2) and 500 g/crop (N3). The result showed that application of chicken manure had a significant influence on the growth and yield of pokem. Plant height, shoot dry weight, number of seedling, and grains weight were high under pokem that had manure fertilizer compared to unfertilizer crop. Chicken manure could increase grains yield. The higher yield were found at N3 treatment (500 g/crop), yet it had not a significant difference with N1 and N2 treatments. It suggested to use 250 g/crop dose of chiken manure, as it was more cost-effective.

Nitrogen was a key component for increasing yield and quality of vegetables like shallots. The growth and development of plants were influenced by nitrogen form. Common plants preferred nitrate for growth, but the enormity preference varies within plant species and other environmental factors. The purpose of this experiment was to study the effect of ammonium:nitrate ratio in sandy soil to growth and yield of shallot (Allium cepa L. Aggregatum group). The experiment had been conducted in August-October 2015 in the sandy land on Samas Beach, Bantul, Yogyakarta, Indonesia. The research was arranged in a Split-Plot design. The main plot was the source of nitrogen (NH4+; NO3-; NH4+: NO3- 1:1; NH4+: NO3- 1:2; and NH4+: NO3- 2:1) and the subplot was cultivars (Crok Kuning, Tiron, and Bima Brebes). Each subplot covered an area of 2.5 m² (2.5 m x 1 m) with three blocks as replications. Shallot bulbs were planted in sixth-row, spacing 20 cm between rows and 15 cm within rows. The dose was applied according to the recommendation of BPTP (urea 200 kg ha-1, ZA 250 kg ha-1, SP-36 150 kg ha-1, and KCl 150 kg ha-1) 144.5 kg N ha-1. Ammonium:nitrate ratio influenced shallot growth in sandy soil through number of leaves at maximum vegetative phase and its leaf area. The NH4+: NO3- 1:2 ratio gave the best result in dry weight of leaves following bulb dry weight than other ratio. Nevertheless, ammonium:nitrate ratio had no significant influence on bulb dry weight (ton ha-1).

A pot experiment was conducted during a two-year period in order to evaluate and compare the salinity tolerance of 10 Iranian commercial cultivars of pomegranate. Pots were arranged in a split plot design with two factors included water salinity as main plot in 3 levels of 4, 7 and 10 dS/m and 10 pomegranate cultivars as sub-plot and 3 replications. The properties concerned during the experiment were vegetative growth, percentage of alive cuttings after 2 month and the necrosis and chlorosis of leaves. In the end of the experiment the vegetative yield and root dry weight were also measured. In addition, irrigation water, drainage water, soil in plots, root, stem and leaves were analyzed for elements such as Na+ and Cl–. The obtained results indicated that the best vegetative growth conditions were related to Voshike -e- Saravan and Tab -o- Larz cultivars at 4 and 7 dS/m salinity levels, respectively. Moreover, the most significant percentage of alive cuttings was related to Voshike -e- Saravan cultivar at each of the three studied salinity levels. Similarly, this cultivar had the minimum values of leaves necrosis and chlorosis at all three levels of salinity. Furthermore, the highest level of fresh yield was related to Zagh cultivar at 4 dS/m salinity level. The highest values of total Na+ and Cl– were observed in shoots and leaves of Zagh and Voshike -e- Saravan cultivars at 10 dS/m salinity level as well. In general, Voshike -e- Saravan is the most salinity-resistant cultivar among 10 studied cultivars. Besides, Malas -e- yazdi and Tab -o- larz can be planted as salinity resistant cultivars in the second hand. Other cultivar cuttings were not resistant in salinity and finally died (even after the second year) and three cultivars of Gabri, Malas -e- Esfahani and Khafri -e- Jahrom were the most sensitive cultivars with the lowest salinity resistance.

ABSTRACT: Weeds have indirect effects on crop plants. Crop development is affected by allelopathy from certain weed species. Allelochemicals from allelopathic weeds can disturb the root and shoot growth of emerging crop seedlings, as well as cause several other types of damage. A study was carried out to investigate the allelopathic potential of Parthenium hysterophorus for weed response in soybean. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangements and replicated thrice. Sowing methods (broadcast and line sowing) were kept in the main plot and mulching treatments (surface mulching and soil incorporation) were kept in the sub-plots. Mulching of Parthenium hysterophorus was applied at the rate of 1.0 t ha-1, 2.5 t ha-1, 5 t ha-1 with control (no parthenium). Manual weed control was also used as treatments. The results revealed that significantly higher shoot length, shoot fresh weight, shoot dry weight, root length, root fresh weigh, root dry weight, number of nodules per plant, nodules fresh and dry weight, number of branches, number of pods per plant, thousand seed weight biological yield, economic yield, dry matter yield and harvest index were recorded with the soil incorporation of Parthenium herbage at the rate of 2.5 t ha-1. Maximum weed density and weed dry biomass were recorded in control plots while weed control efficiency was seen greater in plots where Parthenium herbage was applied to surface at the rate of 5 t ha-1. The results suggested that the use of Parthenium hysterophorus herbage mulching can reduce infestation of weeds by its allelopathic effects and increase the yield of soybean under sub-humid agro-climatic conditions.
