Abstract

Sweet corn (Zea mays L. saccharata) is an agricultural commodity that is very popular with Indonesians, because it tastes sweet and contains high carbohydrates. The need for this commodity continues to increase, but the need for this commodity is not matched by the production produced by farmers. Efforts are needed to increase sweet corn production, one of which is the assembly of superior varieties through plant breeding programs using gamma ray mutation techniques. This study aims to obtain the sweet corn lines with the best morphological appearance in the M3 generation. This experiment was carried out from August to October 2020. The research method used was an experimental method and the design used was a stump factor randomized block design (RBD) consisting of 37 sweet corn lines resulting from gamma ray mutations G1M0, G1M1, G1M3, G2M0, G2M1. , G2M2, G2M3, G3M0, G3M1, G3M2, G3M3, G4M0, G4M1, G4M3, G5M0, G5M1, G5M3, G6M0, G6M1, G6M2, G7M0, G7M1, G7M2, G1M08, G7M2, G1M08, G8M2 , G9M2, G9M3, G9M4, G10M0, G10M1, G10M2, G10M3 and 2 comparator varieties Excotic Pertiwi, and Bonanza F1. Each treatment was repeated 2 times in order to obtain 78 experimental units.

Abstract

The plastic problem had become a global problem, which until now there was no right solution to solve it. The agricultural sector in plant cultivation activities from upstream to downstream was quite a lot of plastic waste produced, one of which was the massive use of plastic mulch in horticultural cultivation. Therefore it is necessary to develop the use of mulch with natural materials that are more environmentally friendly. This study aims to determine the effect of the application of mulch based on straw and rice husks on the growth and yield of paria Lipa F1 varieties in Pakisjaya, Karawang. The research was conducted in Telukbuyung Village, Pakisjaya District, Karawang Regency for 3 months from August to November 2020. This study used an experimental method with a Randomized Block Design (RBD) as the environmental design. The treatment given was giving mulch to the cultivation of pariah plants which consisted of 4 levels of treatment (A. Control / No Mulch, B. Black Silver Plastic Mulch, C. Rice Straw Organic Mulch Carpet, D. Organic Rice Husk Mulch Carpet) and repeated as many as 6 times so that there are 24 Trial Units. The results showed that the application of various mulching showed a significant effect on the growth and yield of bitter melon variety of Lipa F1 in Pakisjaya, Karawang. Silver black plastic mulch had the highest average value on observed parameters among other treatments, but the use of organic mulch carpet made from straw and rice husk had the potential as an alternative in mulching in horticultural cultivation.

Abstract

Good quality cajuput seedlings procured from generative propagation are essential, since the mature trees will be functioning as oil production trees, stock (parent) plant for stem cuttings, and major players on land conservations.In addition to superior genetic factors, the so-called Plant Growth Promoting Rhizobacteria (PGPR) treatment with the optimum concentration would help in enhancing the quality of generative seedlings. Therefore, systematic experiment is needed to determine the effective concentration of PGPR required for preparing high quality cajuput seedlings. This study used Completely Randomized Design (CRD) experiment with randomly assigned concentration of PGPR on cajuput juvenile as the primary factor. The height growth and root length growth of the juvinile for given period of time were measured to evaluate the effect of PGPR treatment. There were monotonically improvement on juvinile’s height and root length growth after PGPR treatment, showing a positive correlation between the height and root length. During the experiment, the highest PGPR concentration of 90mL/L was discovered to be the most effective. Nevertheless, they still had not reached the saturation point yet, therefore, more study is needed to determine the most optimum PGPR concentration to produce the exemplary cajuput seedlings.
