ABSTRACT

Mango (Mangifera indica L.) is a tropical fruit plant that is favored by the community, market demand and public acceptance of mango consumption is increasing, so the propagation of mango plants needs to be further developed, one of which is grafting techniques. The advantages obtained from the grafting technique on mango seeds are that the plant has new superior characteristics, relatively short seed preparation, faster fertilization and reproduction, higher productivity compared to seed propagation, more uniform plant growth, control process pests and diseases more easily. This research aims to study the method of propagation of mango plants by grafting techniques and was conducted using survey and observation methods in Tulusrejo Village, Pekalongan District, East Lampung Regency, Lampung Province. The results of field observations showed that in terms of location, soil conditions, equipment owned, and skills possessed by farmers in Tulusrejo Village were appropriate and quite good in producing mango seed propagation by grafting technique. The steps of this mango grafting technique include seeding mango seeds for rootstock, transplanting rootstock seedlings to the field, selecting buds, implementing grafting, and maintaining seedlings.

ABSTRACT

Rice is a food crop commodity that plays a very important role in the economic life of Indonesia. Rice production which tends to decline due to the lack of application of innovation in rice cultivation. One of the efforts that can be done is by applying the SRI (System of Rice Intensification) method. The application of the SRI method has a major problem, namely the very rapid growth of weeds. This research was carried out in the rice fields of Pasar Ambacang Village, Kuranji District, Padang City, from November 2020 to April 2021. The study aimed to obtain the interaction between the application of organic mulch on the growth and yield of three rice varieties and to obtain the best type of organic mulch for the growth and yield of three varieties of lowland rice, and to get the rice variety that gives the best growth and yield with the SRI-jajar legowo 4:1 method. This study used a factorial Completely Randomized Design (CRD). The first factor is the type of organic mulch which consists of 2 levels, namely straw mulch and reeds mulch, the second factor is the rice variety which consists of 3 varieties, namely the Batang Piaman variety, the Anak Daro variety and the IR 42 variety. Observational data were analyzed using the F 5% test. The results obtained indicated that there was an interaction between the application of organic mulch to the three varieties of rice using the SRI-Jajar Legowo 4:1 method on weed biomass, plant height, number of unhulled grains and number of pithy grains, and the best result was obtained using organic mulch of alang-alang (cogon grass) weed on the growth and the yield of the Anak Daro variety.

ABSTRACT

The use of biological fertilizers (Biofertilizer) is a form of application of the concept of integrated agriculture that is environmentally friendly and sustainable. The purpose of this study was to obtain local microorganism products from organic waste with the addition of golden snail extract which was able to increase the growth of cucumber plants. This experiment was arranged according to a randomized block design with 5 treatments, which consisted of a positive control (watering with NPK), a negative control (watering with water) and 3 treatments of watering with MOL. Parameters observed in this study were plant height, number of leaves, root length, stem diameter, plant wet and dry weight. The research data were analyzed by means of variance using statistical applications 8, if they were significantly different, they would be further tested using LSD at the 5% level. The results showed that the introduction of 5% MOL tofu waste with Mas Conch Extract gave the best results in stimulating the growth of cucumber (Cucumis sativus L.) plants.

Key words : biofertilizer, cucumber, plant growth.

ABSTRACT

The purpose of this study was to determine the effect of compost sludge waste from the Palm Oil Mill rice productivity using SRI modifications. The rice variety used is Batang Piaman. This study used a Completely Randomized Design (CRD) with five treatment sludge compost doses, namely 0 t.ha-1 (control), 10 t.ha-1, 15 t.ha-1, 20 t.ha-1 and 25 t.ha-1 repeated three times. The results showed that the compost sludge of Palm Oil Head Factory significantly affected the parameters of observing plant growth rate, net assimilation rate, maximum number of tillers, number of productive tillers, and weight of milled unhusked rice. The best dose of sludge fertilizer for rice production is the 20 t.ha-1 sludge compost dose which can increase rice productivity by approximately 90% compared to the productivity in the Batang Piaman Vaietas description.
