Planting Season

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

Mulch Cover

Tuberose is one of the most important ornamental plants in Indonesia which the demand continuously increases. However, tuberose is commonly cultivated in drained rice fields and this resulted in various problem such us weed and insect infestation especially mealybug in dry season. In this regard a study was conducted in Malang Regency at Karangploso Experimental Station of East Java Assessment Institute for Agriculture Technology from March 2012 to April 2013. The study employed an experimental method using a randomized block design. Two varieties of tuberoses, i.e., Dian Arum (double flowering) and Roro Anteng (semi-double flowering) were planted on a prepared soil bed. Both tuberose varieties were treated by a silvery plastic mulch cover on one bed and none on the other. Results showed significant differences between the mulch and without mulch treatments in terms of plant growth and flower production.  Flower production obtained from mulch treatment was 3.8 stalks/clump or 34.22 stalks/m2, whereas that without mulch was 2.47 stalks/clump or 27.44 stalks/m2. Meanwhile the damage intensity caused by mealybug infestation on the mulch treatment was 15.21%, while that without mulch  was 22.17%.  In fact, the use of mulch could reduce the weeding cost up to 66.67 % and the total production cost up to 20.86%. The result obtained from R/C ratio analysis with mulch treatment was 2.59 whereas that without mulch was 1.71.Keywords: Polianthes tuberosa ; mulch;  weed,  pest; yield; R/C ratio

Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

This study was conducted in Balai Benih Induk (BBI) Luwus, Baturiti District, Tabanan Regency, with the high of place 506m above sea level occurring in March to May 2014. This research used randomized block design arranged per factor, namely population of plants (P) including three steps: P1=80.000 plants per hectare, P2= 100.00 plants per hectare, P3= 120.000 per hectare; and mulch (M) that include: M0= without mulch and without cleaning, M1= without mulch with clean weeding, M2= rice plants straw mulch (5 ton per hectare) and M3= black silver plastic mulch. Eventually, there were 12 combination treatments, each of which was repeated 3 times to obtain 36 land slots. The research indicates that there was no real interaction between the treatment of plant population and mulch usage in all variables observed. The 100.000 plant population per hectare can produce the weight of dry and fresh oven corn kernel without highest cornhusk that was to say 4.79 tons and 0.53 tons or 11.66 % and 20.45% higher compared to 120.000 plant population per hectare. The use of black silver plastic and rice plants straw mulch can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare each of which is 4.69 tons, 4.57 tons, and 0.54 tons, 0.47 tons or 26.76%, 38.46 %, and 23.51 %, 20.51 % higher than without mulch and without clean weeding. Clean weeding treatment can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare with its weight of 4.63 tons and 0.51 tons or 25.35 % and 35.90 % higher than without mulch and cleaning. Clean weeding treatment was not obviously different from mulch treatment. The identification of weed types were 19 kinds of weeds and Cyperus rotundus L. Weeds. They have the highest density and each absolute frequent of 1249.333 stems m-2 and 1.00.

Tomato was grown in Fall 1997 with swine effluent or commercial soluble fertilizer in a plasticulture production system. Four cultivars, `Mountain Delight', `Celebrity', `Equinox', and `Sunbeam', were transplanted to raised beds with plastic mulch and drip irrigation. Preplant fertilizer was not applied. Effluent from the Wiley L. Bean Swine Demonstration Unit's secondary lagoon was filtered through in-line screen filters and applied directly to the plants through the irrigation system. Toward the end of each application, sodium hypochlorite was injected in the line to achieve a free chlorine concentration of ≈1%. Clogging of filters or drip emitters did not occur. Control plants received 100 ppm N from soluble fertilizer injected in irrigation lines supplied by a municipal water source. Number and weight of tomatoes from plants receiving swine effluent were equal to that of plants receiving soluble fertilizer. No differences in fruit quality were evident between treatments. Plant dry weight was also equal for three out of four cultivars. No differences in soil characteristics were detected between treatments after the study. Chemical analysis of the effluent showed a pH of 7.8 and nutrient concentrations of ≈110 ppm NH4-N, 57 ppm P2O5, 150 ppm K2O, and trace amounts of Cu and Zn. Though no differences in yield were detected in this study, the effluent's high pH and high NH4-N content need to be managed more closely for commercial tomato production.
