Abstract

Soybean is an important commodity as a source of protein, raw material for various food industries and animal feed ingredients. Some of the factors that have led to an increase in domestic soybean demand are increased public awareness of nutrition and protein, increasingly high prices for animal-based side dishes, widespread use and export of soy sauce, and the shifting of the soybean processing industry from home industries to medium to large industries. This is also supported by one of the government programs since 2017-2021, namely the development of soybean plants nationally. The development of these commodities certainly requires the right quality seed, quantity, place, time, and price. With the rolling of the business program to increase production of each commodity, the potential need for quality seeds is quite large. The need for developing soybean seeds in ENT is quite high. Kupang State Politics as a vocational education institution in agriculture needs to develop a business unit for raising soybean seeds. This PPUPIK activity was carried out in 2018-2020 and after PPUPIK in 2021 it has the aim of making the  State Agricultural Polytechnic of Kupang a center for certified soybean seed production that is commercial and available continuously. Keywords: seeds, soybean, certified, PPUPIK, ENT

Abstract

Using quality seeds could increase crop production, including kidney bean, "Inerie", cultivar. The qualified seeds providing enough food supply in the endosperm as a primary energy for a normal and strong germination (viability) and seedling growth (vigor). Seeds from harvested yield are stored for the next planting season. During storage the quality of the seeds will be deprived physically, physiologically and chemically, impact on the production. One way to overcome the drawbacks of the deteriorated seeds is by osmoconditioning using Polyethylene Glycol solution. Osmoconditioning strongly influenced by the osmotic potential and duration of osmoconditioning. The results showed that: 1) Osmoconditioning using PEG-6000 during invigoration affect the electrical conductivity and the chemical content of seeds, which has been deteriorating during 1 year storage; and 2) There is an interaction between osmotic potency and duration of osmoconditioning using PEG-6000 in relation to the electrical conductivity and chemical composition on the seed during 1 year storage. -1.0 MPa with 1 hour osmoconditioning gave the best effect on the electrical conductivity, the levels of free fatty acids and P-total of the “Inerie” seeds.Keywords: Kidney bean, osmotic potency, duration of osmoconditioning, deterioration, Polyethylene Glycol.

Abstract

The research was designed to study the effect of kinetin to and the interaction yield and seed quality  variety mung bean Fore Belu during the drought stress at generative stage. It was conducted from April until September 2007 at Kupang This research was arranged in Completely Randomized Design (CRD) based a factorial experiment (3x4) with three replications. The first factor was soil water content showing the level of drought strees, i.e. soil water content 100% field capacity, soil water content 75% field capacity, and soil water content 50% field capacity. The second factor was the concentration of kinetin i.e. 0, 20, 40 and 60 ppm. Furthermore, the seeds obtained from pot experiment were planted to know quality seeds. Data were analysed using analysis of variance, significant level at 5%, continued with DMRT 5%. The result showed that the drought up to soil water content 75% and 50% field capacity during reproductive stages of variety mung bean Fore Belu decreased yield and seed quality of mung bean. Kinetin sprayed on the leaves was effective to increase yield of mung bean. Concentration 60 ppm of kinetin indicated most the effective concentration to increase the growth and yield of variety mung bean Fore Belu. However concentration 40 ppm have been can give good response to yield of mung bean. Seed quality variety mungbean Fore Belu was not influenced by kinetin giving. A webinar is an online event that is hosted by someone broadcast to a select group of individuals online. (A webinar is sometimes also referred to as a “webcast”, “online event” or “web seminar”.) You should learn about webinar companies here. There was no interaction between drought strees with giving of kinetin to yield and seed quality variety mungbean Fore Belu.Keywords: Kinetin, drought stress, mungbean, generative

Abstract

Palm is one of the ornamental plants which attracted many people. It is a tropical and subtropical plant which requires full sun. Princess Palm (Veitchia merilli) is one of the most desirable palm and is potential as ornamental plants of high economic value. It  is one of  palm species which is propagated by seed. Seed should germinate quickly in order to get palm seedlings in a short time. Slow germination is an obstacle in the cultivation of palm,  because the palm seed coat is very hard, thus inhibiting seed germination process. This research aimed at determining the influence of chemical treatments on the germination of Princess Palm.  This research was conducted in the screen house of laboratory of horticulture Kupang State Polytechnic of Agriculture between June and August 2015. The research design used in this study was randomized block design (RBD). The treatments used were: no chemical treatment, H2SO4, KNO3 and combination of  H2SO4 and KNO3. The results showed  that the chemical treatment affects the germination and seedling growth of Princess Palm. H2SO4 and KNO3 treatment gives best germination palm especially in terms speed growth and value of germination.  Keywords: Palm, Chemical Treatment, Germination, Seed

Abstract

The productivity of tomato plants in East Nusa Tenggara (NTT) in 2016 reached 4.70 tons/ha, increasing by 17.66% from 2015. However, the harvested area decreased by 6.74%. Based on the above data, there is an increase in tomato productivity in NTT but still low compared to national productivity of 15.31 tons/ha. Some of the possible differences in productivity, in addition to the decline in harvested area are also caused by inadequate cultivation techniques that include plant density regulation and other cultivation measures. The purpose of this study was 1) to examine the effect of plant density on growth and yield of tomato plants cut by apical buds and 2) to obtain the best size of plant density that can increase the growth and yield of tomato plants. This study used a randomized block design with a planting distance factor consisting of 8 treatment levels with 4 replications: spacing of 50cmx40cm, 60cmx40cm, 70cmx40cm, 50cm x 50cm, 60cm x 50cm, 70cm x 50cm, 60cm x 60cm, 60cm x 60cm and 70cm x 60cm. The results showed that plant density had an effect on plant growth, namely stem diameter and number of productive branches, and influenced the yield of tomato plants namely fruit weights, plant density/spacing of 70 cm x 40 cm and 70 cm x 60 cm had the best influence on plant growth and fruit weight per plant highest (1037.19grams/plant and 907.50 grams/plant) of  betavila variety.
