Correlation and path coefficient analysis aid in developing breeding strategies aimed at increasing yield traits through selection by providing a better understanding of the relationship. This study was conducted on yield and yield-related traits to determine their direct and indirect effects among thirty-one kenaf mutant lines to identify selectio...

Nine morphologically distinct kenaf genotypes were hybridized to produce 36 hybrids following a half diallel mating design. The combining ability and gene action of 15 yield and yield components were assessed in hybrids and their parents across two environments. Except for the mid diameter and plant height traits, there were highly significant diff...

The growth of the greenhouse chili industry is rapidly increasing in the world including Malaysia. Currently, compost is the most popular growing media. Four fertilizer formulations commonly used by farmers (Local), including the recommended Cooper, Bennoit and Cooper Modified formulation, were evaluated in combination with two volumes (400 and 750...

Drought stress has now become a severe threat to ensure food security in the developing world as well as in Malaysia. To dertermine physiological and molecular determinants of drought stress and screening of drought tolerant rice varieties, an experiment was conducted in a greenhouse at Universiti Putra Malaysia using eleven rice varieties and two...

Drought is a major limiting factor affecting rice yield and productivity all over the world, including Malaysia. To induce drought resistance, there is an increasing interest in using different phytohormones for field crop production considering its efficiency, feasibility, cost and labour-effectiveness. A greenhouse experiment was conducted to eva...

Experiment was conducted under sub-tropical condition to investigate the variations in some morphological features, growth, reproductive characters and its impact on seed yield using correlation coefficient in 15 promising mungbean mutants and cultivars. Correlation study revealed that among the traits investigated, leaf area was the most important...

14 The study was conducted under rain shelter condition at Universiti Putra Malaysia to 15 evaluate the effect of Azospirillum brasilense Sp7 inoculation on chili plants grown in 16 coconut coir dust media (with and without compost) and moderate (40 %) water 17 deficient condition. Five treatments were tried; Inoculated compost and full irrigation...

Salinity is one of the most serious abiotic stresses that cause reduction in plant growth and yield. A field experiment was conducted at Satkhira (Bangladesh) in 2010-2011 to evaluate salinity tolerant rhizobia strains isolated from saline area. There were seven biofertilizer treatments viz. five rhizobia strains L-19, L-68, L-292, L-304 and L-335...

Interaction between bacteria and arbuscular mycorhizae has been known to benefit growth of plants in over the world. An investigation was conducted to evaluate the growth and yield of rockmelon plant (Cucumis melo) as influenced by Burkholderia cepacia and Glomus mossae in a soilless culture (70% coconut dust+30% empty fruit bunch compost). Four tr...

Three fertilizer formulations namely; (M), a local formulation commonly used by farmers, the recommended Cooper standard (CS), and Benoit (BEN) suggested for the lower cost of production were evaluated in combination with four levels of pyroligneous acid (0, 10, 20 and 30%) for enhancement of growth, fruit yield and quality of rockmelon in soilless...

Effects of soilless media coconut dust (CD) and empty fruit bunch (EFB) and five electric conductivity (EC) levels of fertilizer (0.5, 1.0, 1.5, 2.0 and 2.5 dS/m) on growth, yield and fruit quality of rock melon were investigated under greenhouse conditions. Plant height, number of leaves, total leaf area, chlorophyll content, dry weight of leaf, s...
