An experiment was conducted to assess the effect of corm size and varieties on corm/cormels production and vase life of gladiolus ( Gladious grandiflorus L.) under Chitwan condition. A Field experiment was conducted in a farmer’s field at Gunjanagar VDC, Chanauli, Chitawan during November 2008 to April 2009. The experiment consisted of 12 treatment combinations laid out in two factorial Randomized complete block design (RCBD) with three replications. Four sizes of corms viz. 2-3 cm, 3-4 cm, 4-5 cm and 5-6 cm and three varieties viz. American Beauty, Interpret and Yellow Summer Sunshine formed 12 treatment combinations. Laboratory experiment was conducted to determine the effect of corm size and varieties on the vase life of harvested cut spikes of gladiolus at ambient temperature at the central laboratory of the Institute of Agriculture and Animal Sciences (IAAS), Rampur, Chitwan, Nepal. Corm size and varieties significantly affected corm/cormels production and vase life of gladiolus. Large sized corms (5-6 cm) performed better with respect to number of daughter corms and cormels per plant. Similarly, large sized corms (5-6 cm) showed better performance with respect to postharvest behavior such as total number of florets opened/spike (11.40), days to first and 100% floret withering as compared to small sized (2-3 cm) corms. Significant variation among three varieties was observed in most of the characters. Numbers of daughter corms were found highest in Yellow Summer Sunshine while maximum numbers of cormels/plant were found in Interpret. Similarly, Interpret proved best having more number of florets opened per spike and more days needed to first and 100% floret withering.DOI: http://dx.doi.org/10.3126/njst.v12i0.6477 Nepal Journal of Science and Technology 12 (2011) 35-40

A field experiment was conducted from August to November, during the 2012 and 2013 cropping seasons at the Research Farm, University of Agriculture, Makurdi, Nigeria, to identify the optimum plant density of okra and intercropping effects on yields of egusi melon-okra mixture and to assess the yield advantages of the intercropping system. The experiment was a 3x3 split plot arrangement of treatments, fitted in a randomized complete block design (RCBD), replicated four times. The intercropping (sole egusi melon, sole okra and egusi melon-okra mixture) constituted the main plots, while the population densities of okra (33,000, 40,000 and 50,000 plants ha-1 equivalent) into egusi melon were allocated to the subplots. Results of study showed that to maximize intercrop yield of okra in an egusi melon-okra intercrop, the optimal population density of okra is 33,000 plants ha-1, while that of 40,000 plants ha-1 is optimal to maximize intercrop yield of egusi melon. Intercropping egusi melon and okra significantly (P≤0.05) reduced yields of egusi melon (37.5 % and 40.5 % respectively, in years 2012 and 2013) and that of okra (9.7 % and 16.9 % respectively, in years 2012 and 2013). The highest mean land equivalent ratio value of 1.57 and highest land equivalent coefficient values of 0.60 and 0.63 respectively, in years 2012 and 2013, were recorded for okra sown into egusi melon at the population density of 40,000 plants ha-1. It is most advantageous having both crops in intercrop when okra is sown into egusi melon at the population density of 40,000 plants ha-1. This should therefore be recommended for Makurdi location, Nigeria.

The aim of this research was to investigate the effect of stand density on seed yield and protein content in sunflower hybrids. The field experiment was carried out at Rimski Sancevi location. Six NS sunflower hybrids were examined. Five hybrids are confectionery (NS Goliat, NS Slatki, NS Gricko, Vranac and Cepko), and one is used for bird food (NS-H-6485). The trial was arranged as randomized complete block design (RCBD) with four replications. Sowing was done with six different densities (from 20,000 to 70,000 plants per hectare, with an increment of 10,000 plants per hectare). Analysis of variance (ANOVA) showed that the effect of hybrid, stand density and hybrid ? stand density interation were highly significant for seed yield and protein content. The highest seed yield, on the basis of average for all densities, was found in NS-H-6485 (4.77 t ha-1) and in NS Gricko (4.43 t ha-1). Average seed yield of hybrids significantly increased up to 50,000 plants per ha-1, when it reached the value of 4.50 t ha-1, and then decreased. Significantly higher protein content, taking into account all stand densities, showed hybrid Cepko (16.94%). Protein content, above the overall average value, was achieved in hybrid Vranac (16.11%). The high?est protein content in the average for all six hybrids was at the lowest stand density (20,000 plants per ha-1), and then decreased up to higher densities. The results showed that stand density had significant effect on seed yield and protein content in sunflower hybrids.

The objectives of the study were to determine the relationships among the physiological characters and productivities of nine PGL clones in medium land. Field trial was arranged in a Randomized Complete Block Design (RCBD) single factor with three blocks as replications. The treatment was PGL clones, consisting of nine clones, namely PGL 1 PGL 3, 4 PGL, PGL 7, PGL 10, PGL 11, PGL 12, PGL 15, and PGL 17. The observations were done on several variables of physiological characters and productivities. Data were analyzed by using the Analysis of Variance (ANOVA) at 5% levels. If there were significant differences among the treatments, they will be analysed by Duncan Multiple Range Test (DMRT). The relationships among variables were determined using correlation analysis. Results showed that there were wide variations in the stomatal density and width openings  and also productivities among the nine PGL clones. Stomatal density and width openings have significant positive correlation with the productivity. PGL 12 and 15 with a denser of stomatal arrangement and wider stomatal openings have higher productivities when compared to other PGL clones, especially PGL 7 with the most loosely stomatal arrangement and narrower stomatal openings.
