Abstract

The experiment was conducted in the field at dryland farming areas at Cengiling village, Jimbaran, district of South Kuta, Badung (50 m asl), from 9 March until 3 June 2008. The objective of the experiment was to study the effects of plant population on grain yield, and forage production of corn varieties, plantedat the end of rainiy season. A randomized complete block design was used in this experiment, in which treatments were arranged factorially. The treatments were plant population (71,428; 142,857; 214,284 and 285,712 plants ha-1 or one, two, three and four plants hole -1), and corn varieties (BISI-2, CPI-2, Srikandi Putih and Local Bukit). All treatments were replicated three times. Results of the experiment indicated that interaction effects between plant population and variety were significant on grain yield and straw quality of corn. Variety of Local Bukit at population of 285,712 plants ha-1 resulted in the highest grain yield at 12% moisture (9.39 t ha-1), and grain oven dry weight (6.28 t ha-1). ). That variety at that population gave higher forage crude protein (7.66%) than that given by variety CPI-2 but was not significantly different from that given by BISI-2 and Srikandi P. The variety of Local Bukit at that population also resulted in lower forage crude fiber (18.16%) than the value given by the other varieties. The highest population resulted in the highest fresh and oven dry weights (22.76 dan 14.36 t ha-1) of forage. Variety of Local Bukit and BISI-2 gave higher (12.39 and 14.01 t ha-1) oven dry weights than the other varieties. In this experiment the optimum plant population for maximum grain yield and quality of forage for each corn varieties had not been obtained.

Abstract

Water availability is a major limiting factor to the growth and yield of rainfed rice.  Systemof Rice Intensification (SRI), which is an efficient method of planting rice, particularly inthe use of water, number of seeds per hill and time of transplanting seedlings, has beenapplied generally in irrigated rice but it is rarely practiced in rainfed rice.A field experiment, which was aimed to study the effect of number of seed/hill and variationof plant spacing on the growth and yields of rainfed rice with SRI (System of RiceIntensification), was conducted during dry season from April until September 2012. Thelocation was at Patemon Village, District of Seririt, Buleleng Regency, Bali, at the altitudeof 100 meter asl. In this experiment a completely randomized block design was used and thetreatment were arranged factorially. The first factor was the number of seeds (1,2,3 and 4)/hill and the second one was the plant spacing (20 cm x 20 cm, 25 cm x 25 cm and 30 cm x 30cm). All treatments were replicated three times.The results of the experiment showed that the interaction between one seed/hill and plantspacing of 30 cm x 30 cm resulted in significantly (P<0.05 and P<0.01)  the highest fresh(4.387 ton/ha) and oven dry weight of grains (3.633 ton/ha), oven dry weight of 1000grains (20.920 g) and the harvest index (31.163%). The gross margin analysis indicatedthat the variable costs were higher than the gross income for all treatment, due to high costof watering
