#glutinous corn

The research was conducted at the Cagayan State University at Lal-lo from June 2017 to March 2018 to establish a CSU demonstration farm for cacao-based integrated multi- story cropping system by intercropping mungbean (Vigna radiata L.) and glutinous corn (Zea mays) during establishment stage of cacao farming and to showcase its economic potential. Specifically, it aimed to determine the following: the plant height, number of leaves, survival rate, leaf area index, plant height of glutinous corn and mungbean, pods of mungbean, length of corn ear, yield per plot(kg) and return of investment. It was laid out in Randomized Complete Block Design (RCBD) with three treatments and replicated three times. The treatments were: T1- cacao as control, T2- cacao + glutinous corn and T3- cacao + mungbean. No significant differences among the treatments on the plant height, number of leaves, and leaf area index. However, there are significant differences in terms of survival rate, plant height of glutinous corn and mungbean, pods of mungbean, length of corn ear, yield/plot (kg). Grafted cacao seedlings intercropped with glutinous corn produced highest net income and return on investment compared to mungbean. Therefore, planting cacao intercropped with glutinous corn is recommended to the Lal-lo farmers to obtain higher income during the establishment stage. Another trial must be conducted to give more conclusive results and another research must be conducted using other intercropped.

Functional corn is a special corn that has distinctive properties, namely containing higher nutrients than other corn. One of the things that affect the quality of corn is fertilization in the growth phase. This study aims to determine the most appropriate fertilizer dosage for 2 functional corn varieties. The research was carried out in Bone Regency, South Sulawesi Province. This research lasted for three months, starting from December 2023 to March 2024. This study was prepared using a separate plot design with 3 replicates consisting of 2 main plot treatment levels, namely glutinous corn and purple corn and the treatment of plot children, namely fertilizer doses: 100 kg, 200 kg and 300 kg. The results showed that the purple corn variety gave a better response to the parameters of plant height observation at the 4th week 54.8 cm, the number of leaves at the 4th week 8.5 pieces, the male flowering age was 45.0 DAP and the female flowering age was 47.5 DAP. Meanwhile, the NPK fertilizer dose of 300 kg/ha gave a better response to the parameters of the number of leaves in the 8th week of 12.9 cm, the weight of the cob with the cob was 98.4 grams and the weight of the cob without the cob was 84.0 grams. There was also an interaction between purple corn with a dose of NPK fertilizer of 300kg/ha on the parameters of cob weight per hectare of 5.58 tons/ha and dry seed weight per hectare of 4.24 tons/ha.

This study evaluated the effects of vermichar on soil chemical properties, growth, yield, and economic returns of glutinous corn (Zea mays L.). It aimed to determine the optimal vermichar application rate and compare its performance with conventional NPK fertilizers. Treatments included vermichar at 5, 10 and 15 bags per hectare, alone or combined with NPK. Results showed that vermichar significantly improved soil pH, organic matter, and nutrient levels especially nitrogen, phosphorous, and potassium when applied with commercial NPK. The best soil improvement and highest yields were observed with 10-15 bags per hectare. Growth metrics such as plant height, ear size, and biomass increased with these treatments. While combining vermichar with NPK boosted yields, the highest return on investment was achieved with vermichar alone at 10 bags per hectare, outperforming the sole use of commercial fertilizer. This highlights vermichars potential as cost-effective and sustainable soil amendment. The study recommends using vermichar at optimized rates, particularly 10 bags per hectare for improved soil health, yield and profitability in glutinous corn production.

The study was conducted to demonstrate the performance of four varieties of glutinous corn during wet season in the province of Cagayan, in terms of agronomic and economic characteristics. Specifically, it aimed to find out the best suited corn variety under CSU Lal-lo condition during wet season in terms of: (a) plant height (cm); (b) length of corn ear (cm); (c) rows per ear; (d) ear diameter; (e) weight of 1000 kernels dried and fresh (g); (f) yield per plot (kg) and cost and return analysis. The treatments were: T1 (Lagkitan), T2 (Nutri Lyt), T3 (Batik) and T4 (Purple gem). These were randomly allocated in the different plots following the Randomized Complete Block Design (RCBD). The result of the study did not show significant difference in terms of plant height (cm) at 30 days, plant height (cm) at 60 days, length (cm) of corn ear, weight (g) of 1000 dried kernels, weight (g) of 1000 fresh kernels and yield (kg) per plot. However, it showed significant difference in terms of number of row per ear and ear diameter. Results further shows that purple gem produced the highest number of rows per ear and widest ear diameter. In terms of ROI, all the treatments showed positive ROI but the highest was gained by Treatment 4 (purple gem) with 297. 29%.
