[EFFECT OF CONCENTRATION AND TIME INTERVAL OF BABANDOTAN BIOPESTICIDE SPRAYING ON THE INTENSITY OF DAMAGE AND YIELD OF KAILAN]. Biopesticides from Ageratum conyzoides plants are used as an alternative in pest control. The used of synthetic pesticides was widespread as an effort in pest and disease control because it worked effectively and quickly, but caused resistance and resurgence of pests were bad impact on the environment for long term. The content of active compounds in Ageratum conyzoides plants such as flavonoids, anthraquinone, tannins, terpenes, phenols, saponins, alkaloids and steroids worked as controllers of various cultivated plant pests. This study aims to determine the spraying concentration and interval of spraying Ageratum conyzoides on the intensity of damage and yield of kailan plants. This research was conducted in November 2020 - January 2021 at Agroecotechnopark research land, Diponegoro University, Semarang. The experimental design used was a factorial Randomized Complete Block Design with 3 replications. The first factor was spraying concentration (10%, 30% and 50%) and the second factor was interval of spraying (once every 5 days, 10 days and 15 days). The variables observed were absolute damage rate, relative damage rate, plant height, number of leaves and fresh weight of kailan. Data were analyzed by Analysis of Variance followed by DMRT (Duncan's Multiple Range Test). The results showed that Ageratum conyzoides biopesticide was able to control pests and and to support kailan growth. Spraying babandotan biopesticide at a concentration of 50% has been able to reduce the rate of crop damage by pests, supported vegetative growth, and increased kailan growth to provide optimal yield. Spraying time interval did not affect all variables.

This study was conducted to evaluate the growth and yield of maize to compost, organomineral fertilizer, and mineral fertilizer at Iyaganku and Moniya farm sites in Ibadan, Oyo State, Nigeria. Treatments consisted of Organomineral fertilizer (A), Compost (B), Fresh compost (C), Mineral fertilizer (D = N.P.K. 15:15:15), and Control (E = no fertilizer). Experimental design was randomized complete block design replicated four times. Compost treatments (45 kgNha-1) were applied at one week before sowing while N.P.K. 15:15:15 fertilizer (300 Kg N ha-1) was applied two weeks after sowing. The growth and yield data collected were analyzed using Analysis of Variance (ANOVA) of GENSTAT Discovery software. Significant means were compared using Duncan Multiple Range Test (DMRT) at p = 0.05. The results of the analysis revealed no significant difference in the number of leaves and stem girth at 8 weeks after sowing (WAS) at Iyaganku. Tallest maize plants were recorded from plots treated with A and B. Also, treatments showed no significant difference in the dry weight (g/cob) of husked and unhusked maize at harvest. At Moniya, plots treated with A produced high number of leaves while lowest number of leaves were recorded from control plots and plots treated with B, C, and D. Similarly, no significant difference was observed in stem girth, plant height, dry weight (g/cob) of husked and unhusked maize at harvest between control plots, and plots treated with C, and D. Larger stem girths, tallest plants, dry weight (g/cob) of husked and unhusked maize at harvest were observed in plots treated with A and B. The results from Moniya farm site suggest that organomineral fertilizer and compost have the potential to enhance the growth and yield of maize in studied location.

Flooding is the most important abiotic stress in the tropical and subtropical regions that negatively affects terrestrial plant growth and productivity and even leading to plant death. Amino acid accumulation, on the other hand, may serve as defense during stress resulting to tolerance among others. Thus, a study was conducted to determine the growth, root length and number of leaves produced by Philippine native tomato as affected by different levels of amino acid under varying durations of flooding. Data were statistically analyzed through Analysis of Variance (ANOVA) for Randomized Complete Block Design (RCBD). Comparisons among means were done using Duncan’s Multiple Range Test (DMRT). Shoot growth was increased with application of amino acids (100 ppm) after both flooding conditions (three and six days) at 3.28cm and 7.47cm, respectively. Moreover, no amino acid application or minimal amino acid application (100 ppm) produced the most number of leaves on unflooded and minimally flooded conditions (three days only). On root length, longer roots were produced by plants without amino acid (12.68 cm) or lesser amino acid (100 ppm) at 9.43 cm, while flooding had no significant effect on root length. These results clearly indicate the value of exogenous amino acid (100 ppm) application mainly on shoot growth of tomato. Furthermore, exogenous amino acid application is deemed necessary because even in both number of leaves and root length where results are comparable to without amino acid application, no negative effect was observed.   Keywords - agriculture, flooding, amino acid, Philippine native tomato
