Abstract

The research was conducted to determine the morphological characteristics, productivity andquality of Napier grass cultivars Taiwan, King and Mott harvested at 8 and 13 after planting. Effect ofcultivar and harvest arranged in a nested design (3x2). The variables were observed consisting ofmorphological characteristics, dry matter production and forage quality. The results showed that themorphological characteristics, leaf stem ratio, fiber content, crude protein content and in vitro dry matterdigestibility of Napier grass Taiwan and King cultivar were not different, but both morphologicalcharacteristics, fiber content was higher (P <0.05) compared to Mott cultivar, whereas leaf stem ratio,crude protein content and in vitro dry matter digestibility Mott cultivar was higher (P <0.05) comparedto Taiwan and King cultivars. In general, an increase in plant height and fiber content at the age of 13weeks, whereas crude protein content and in vitro dry matter digestibility decreased. It was concludedthat the highest dry matter production found in Taiwan and the King cultivars, whereas highest qualityfound in Mott cultivar. Dry matter production was highest harvested at 13 weeks, whereas the highestquality harvested at 8 weeks after planting for all cultivars tested.

Abstract

A field experiment was conducted on Chromolaena odorata dominated pasture with the objectivesof evaluating efficacy of integrated of mechanical and cultural control on weed suppression anddetermining botanical composition of plant species after treatment started. The treatments were, T1slashing of Chromolaena every month, T2 digging up of Chromolanea, and exposed to dry (mulching),T3 digging up of Chromolaena followed by burning, T4 digging up of Chromolaena followed byburning and sowing with Centrosema pubescens and T5 digging up of Chromolaena followed byburning and planting with Brachiaria decumbens. Results of experiment showed that under droughtconditions, digging up Chromolaena was very effective in suppressing regrowth of Chromolaena but itwas not effective to other weeds. Among treatments, digging out of Chromolaena followed by burningand planting with Brachiaria decumbens was the most effective and slashing of Chromolaena everymonth was the least effective in suppressing weeds. Botanical composition was shifted with treatments.Stachytarpheta jamaicensis and Chromolaena were the dominant species in monthly slashedChromolaena plots, Stachytarpheta and Calopogonium muconoides were the dominant species inmulched plots while Mimosa pudica, Brachiaria and Centrosema were the dominant species in burntplots.
TOTAL NON-STRUCTURAL CARBOHYDRATE (TNC) OF THREE CULTIVARS OF NAPIER GRASS (Pennisetum purpureum) AT VEGETATIVE AND REPRODUCTIVE PHASE Budiman, B.; Soetrisno, R.D.; Budhi, S.P.S.; Indrianto, A.

Abstract

An experiment was conducted to determine Total Non-structural carbohydrates (TNC) of threecultivars of napier grass (Pennisetum purpureum) harvested at vegetative and reproductive phases. Thecultivars tested were Taiwan (Gt), King (Gk) and Mott (Gm) and arranged in a 3 x 2 of treatments withfour replicates following nested design. The results showed that the highest sugar content (P<0.01) wasfound in Gt cultivar and the lowest was in Gm cultivar. The highest starch content (P<0.01) was found inGk cultivar and the lowest was in Gt cultivar. TNC content of Gt and Gk cultivars were not significantlydifferent, but both were significantly higher (P<0.01) compared with the Gm cultivar. It can beconcluded, that there were differences in TNC between cultivars, however, the TNC content in Gkcultivar was not different with Gt cultivar, while Gm cultivar have the lowest (P<0.01) TNC content. Atreproductive phase all cultivars have higher (P<0.01) TNC and starch content than at vegetative phase
