Low yield of rice has made reaching self-sufficiency level in Malaysia elusive. So, Malaysia has become a target of rice exporting countries within and outside Asia. To solve this problem, a pre-sowing seed treatment was used as a physiological intervention to alleviate the impeding problems of achieving better growth and yield of Malaysian rice variety MR219. A glass house experiment, which involved the use of solutions of osmotic salts and plant hormones, was used for this investigation. Data on germination percentages, height, number of tillers and productive tillers, tiller efficiency and yield were taken. In both osmopriming and hormonal priming treatments, the highest number of tillers and productive tillers were from pre-germination. The tallest plants from osmopriming were from 150mM treatment, while 50 ppm GA3 had the tallest in hormonal priming. The highest tiller efficiency for osmopriming was from 150mM and and 200mM sodium chloride, while in hormonal priming it was 200 ppm salicylic acid. For yield per panicle in osmopriming, it was 50mM and 100mM magnesium chloride that had the highest, while in hormonal priming it was 200 ppm methyl jasmonate. Finally, the highest grain yield per hill was produced by 200 ppm methyl jasmonate in hormonal priming, while 50Mm magnesium chloride had the highest yield in osmotic priming. So, it is concluded that the use of 200 ppm methyl jasmonate and 50Mm magnesium chloride could be used as potential hormonal priming and osmopriming, respectively, for yield improvement of MR219 rice in Malaysia.

The experiment was conducted to assess the responses of salinity on the growth, nutrient accumulation and yield of rice genotypes. Five Malaysian genotypes (MR33, MR52, MR211, MR232 and MR219), two salt sensitive (BRRI dhan 29 and IR20) and one salt tolerant genotypes (Pokkali) were evaluated in four levels of salinity. Two factors complete randomized design (CRD) was used with four replications. Dry weight of root, shoot and yield significantly decreased with the increase of salinity levels, while MR232 and MR211 were less affected. Na+ ions accumulations increased in the root and shoot with the increase of salinity, while the lowest accumulation was in MR211. Na+/ K+ratio sharply increased in the root with increasing the salinity. Whereas, Ca++/Na+ and Mg++/Ca++ ratio showed decreasing trend with increasing salinity level. The maximum amount of nitrogen and phosphorous accumulation was observed in the shoot of MR211, while Na+ in BRRI dhan29, K+ in Pokkali. The highest accumulation of Na+ and K+ observed in the root of MR219. The maximum Ca++ and Mg++ were found in MR33 and MR211, respectively. Considering all, genotypes MR211 andMR232 were found to be relatively tolerant to salt than the other genotypes. [ABSTRACT FROM AUTHOR]

The effect of biofertilizer and urea on growth parameters, yield and yield attributes of two mungbean varieties was investigated. Application of biofertilizer and urea was more effective in promoting plant growth and yield attributes than sole application of biofertilizer or urea. Among the fertilizer combinations, biofertilizer with recommended TSP, MP, gypsum and one-third urea exhibited superiority in plant height, number of branches plant-1, leaf area plant-1, number of nodules plant-1, chlorophyll content in leaves, total dry mass plant-1, absolute growth rate, number of pods plant-1, harvest index and seed yield as compared to other fertilizer treatments. Therefore, biofertilizer with 13 kg urea ha-1 may be recommended for increasing seed yield of mungbean. [ABSTRACT FROM AUTHOR]

The experiment was conducted at the experimental field of Bangladesh Institute of Nuclear Agriculture, Mymensingh, Bangladesh from the month of March to May 2011 to investigate the effect of cultivars and seed rates on morpho-physiological characters, yield components and yield of summer mungbean [Vigna radiata (L.) Wilczek]. The experiment comprised three types of varieties viz., BINAmung-6 (bold seeded), BINAmung-7 (small seeded) and BINAmung-8 (medium seeded) and three seed rates viz., 30, 40 and 50 kg ha-1. The experiment was laid out in a two factor randomized complete block design with three replications. Number of branches plant-1, leaf area plant-1, total dry mass plant-1, relative growth rate, pod number plant-1, seed and biological yield plant-1 and harvest index decreased with increasing seed rate while reverse trend was observed in plant height and leaf area index. Results revealed that optimum seed rate of a mungbean variety depended on seed size. The variety having smaller size seeds require lower seed rate and vice versa. On an average over the varieties, the seed rate 40 kg ha-1 resulted in the highest seed yield in mungbean. The optimum seed rate for maximizing seed yield of bold seeded variety, BINAmung-6 was 50 kg ha-1. Similarly, the optimum seed rate for small seeded variety, BINAmung-7 and medium seeded variety, BINAmung-8 was 30 and 40 kg ha-1, respectively. The dry matter partitioning to economic yield was also higher at above optimum seed rates of the varieties. Among the varieties, BINAmung-8 produced the highest seed yield both per plant and per hectare due to its favourable dry matter partitioning to economic yield. [ABSTRACT FROM AUTHOR]
