Sbaja a novel foliar applied growth and yield enhancer in Malaysia / Sbaja, um novo potenciador de crescimento foliar aplicado e de rendimento na Malásia

Product efficacy testing during 2006 to 2010 with SBAJA (a novel scientifically formulated foliar-spray growth and yield enhancer) in the greenhouse and multi-location field trials registered measurable increase in chlorophyll contents, robust and healthier crop growth and increased yield and biomass production. In field trial, rice plants receiving normal NPK fertilizer at the rates of 100:50:30 served as control and spray treated with SBAJA at 40 and 60 days after sowing (DAS). All the experiments were laid out in Randomized Complete Block (RCB) Design and replicated five times. Tiller number and panicle characteristics; length, weight, number of grains, number of filled grains were significantly increased with 1:300 SBAJA treatment. In addition, 1000 grain weight and rice yield increased significantly with SBAJA treatments. Normal fertilizer applications in field trials augmented with SBAJA in 2008-2010 in the Selangor North West Project (SNWP), registered measurable increase in rice yields by 25-30% from 6.2 - 6.5 tons/ha to 7.8 - 8.9 tons/ha. It is concluded that foliar spraying with SBAJA at 40 and 60 days after sowing increased growth and yield of rice under green house and field conditions.

Os testes de eficácia do produto durante 2006 a 2010 com SBAJA (um novo spray foliar cientificamente formulado) em estufa e ensaios de campo em várias localizações registraram aumento mensurável nos teores de clorofila, crescimento robusto e mais saudável das culturas e aumento do rendimento e da produção de biomassa. No ensaio de campo, plantas de arroz recebendo adubo NPK normal nas doses de 100:50:30 serviram como controle e foram tratadas com SBAJA aos 40 e 60 dias após a semeadura (DAS). Todos os experimentos foram dispostos no formato Randomized Complete Block (RCB) e replicados cinco vezes. Número de perfilhos e características da panícula; comprimento, peso, número de grãos, número de grãos preenchidos foram significativamente aumentados com o tratamento com 1:300 SBAJA. Além disso, o peso de 1000 grãos e o rendimento de arroz aumentaram significativamente com os tratamentos da SBAJA. Aplicações normais de fertilizantes em testes de campo aumentados com a SBAJA em 2008-2010 no Projeto Selangor North West (SNWP), registraram aumento mensurável na produção de arroz de 25-30% de 6,2 a 6,5 toneladas/ha para 7,8 a 8,9 toneladas/ha. Conclui-se que a pulverização foliar com SBAJA aos 40 e 60 dias após a semeadura aumentou o crescimento e o rendimento do arroz em estufa e em campo.

Effects of organic fertilizers on the growth and yield of bush bean, winged bean and yard long bean

ABSTRACT VC (20%), TC (20%) and N:P:K fertilizer (farmer's practice) were used to determine the growth and yield attributes of bush bean (Phaseolus vulgaris), winged bean (Psophocarpus tetragonolobus) and yard long bean (Vigna unguiculata). Plants grown with VC (20%) produced the highest fresh biomass for bush bean (527.55 g m-2), winged bean (1168.61 g m-2) and yard long bean (409.84 g m-2). In all the tested legumes the highest pod weight, pod number, pod dry weight and pod length were found in the VC (20%) treatment. Photosynthetic rates in the three legumes peaked at pod formation stage in all treatments, with the highest photosynthetic rate observed in winged bean (56.17 µmol m-2s-1) grown with VC (20%). The highest yield for bush bean (2.98 ton ha-1), winged bean (7.28 ton ha-1) and yard long bean (2.22 ton ha-1) were also found in VC (20%) treatment. Furthermore, protein content was highest in bush bean (26.50 g/100g), followed by yard long bean (24.74 g/100g) and winged bean (22.04 g/100g), under VC (20%) treatment. It can be concluded that legumes grown with VC (20%) produced the highest yield and yield attributes.

Fruit development, pigmentation and biochemical properties of wax apple as affected by localized Application of GA3 under field conditions

This study investigated the effects of gibberellin (GA3) on the fruit development, pigmentation and biochemical properties of wax apple. The wax apple trees were rubbing treated with 0, 20, 50 and 100 mgGA3/l under field conditions. The localized application (rubbing) of 50 mg GA3/l significantly increased the fruit set, fruit length and diameter, color development, weight and yieldcompared to the control. In addition, GA3 treatments significantly reduced the fruit drop. With regard to the fruit quality, 50 mg/l GA3 treatment increased the juice content, K+, TSS, total sugar and sugar acid ratio of wax apple fruits. In addition, higher vitamin C, phenol, flavonoid, anthocyanin, carotene content, PAL and antioxidant activities were recorded in the treated fruits. There was a positive correlation between the peel colour and TSS content and between the PAL activity and anthocyanin formation in the GA3-treated fruit. It was concluded that rubbing with 50 mg/L GA3 at inflorescence developing point of phloem once a week from the tiny inflorescence bud until the flower opening resulted in better yield and quality of wax apple fruits and could be an effective technique to safe the environment from excessive spray.
