Abstract

The Combined Effect of Plant Spacing and Varieties on the Growth and the Corn Yields (zea mays l.) at Loes, Sub District of Maubara, District of Liquisa Repupublica Democratica De Timor Leste Plant spacing will affect the density of plant, efficiency of light use, the competition of plants in the use of water and nutrients, and finally will affect the production of plants. Each variety of corn crops requires planting distance suitable for optimal growth and maximum yield. This study aims to determine the best combination of plant spacing and corn varieties in yielding optimal growth and highest yield. The study used Randomized Block Design (RAK) with nine treatments and three replications. The experimental treatments were: a combination of plant spacing of 50 cm x 40 cm and Sele varieties; combination spacing of 50 cm x 40 cm and Noimutin varieties; combination of plant spacing of 50 cm x 40 cm and Nai varieties; combination spacing of 75 cm x 25 cm and Sele varieties; combination spacing of 75 cm x 25 cm and Noimutin varieties; combination spacing of 75 cm x 25 cm and varieties of Nai; combination spacing of 80 cm x 25 cm and Sele varieties; combination spacing of 80 cm x 25 cm and Noimutin varieties; and the combination of plant spacing of 80 cm x 25 cm and Nai varieties. The results showed that the combination of plant spacing of 75 cm x 25 cm and Nai varieties produced the best growth of corn plants, with the highest leaf area (286.35 cm2) and the highest stem diameter (2.787 cm). The highest dried seeds of 13% were found in the same treatment with an average value of 149.60 g per plant and 7.78 tons per hectare.

Abstract

Study of Differences in Entres Saving Media on the Success of Grafting Wani Ngumpen Bali (Mangifera caesia Jack.Var. Ngumpen Bali) Wani (Mangifera caesia Jack.) is a local fruit plant that has a fairly high diversity of 22 cultivars in all wani production centers in Bali. One of the cultivars, namely Wani Ngumpen Bali, has the advantage of producing fruit that does not contain seeds as much as 90% of the total fruit. Due to constraints in generative seed production, wani are propagated vegetatively by means of grafting. Due to the limited time and the number of grafted seedlings, efforts are needed to maintain the freshness of the shoots through storage. The purpose of this study was to determine the best entres storage media for female grafting. This experiment used a Randomized Block Design (RAK), with five treatments, namely no media, sawdust, wet newspaper, wet cloth, and banana fronds. Each treatment was repeated five times and each unit consisted of three plants so that there were 75 experimental units. The data obtained were analyzed descriptively. The treatment of various storage media gave different responses to the success rate of grafting of Wani Ngumpen Bali plants. The best media for storing buds was wet newsprint with a success rate of 26.6% of live seedlings, supported by the number of leaves as many as 15 parameters.
