This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Impatiens balsamina L. is a plant that is widely cultivated in Bali. The flower of this plant is used as a component of offering in Hindu religious ceremonies. The flower petals are thin and wilt easily, therefore genetic modification is needed to get better quality. This research aimed to study the effect of 0.01% colchicine with soaking periods of 4 hours, 8 hours, 12 hours and 24 hours to seedlings of I. balsamina. Seeds of I. balsamina were germinated and sprouted seeds were treated with 0.01% colchicine for 4 hours, 8 hours, 12 hours and 24 hours. The sprouted seeds were then transfer to polybag with soil media. The experiment was designed with randomized blok design with five replicates. Observations were done on plant height, length and width of leaf, stem diameter, number of stomata as well as observation on plant stem cortex cells. Results showed that colchicine reduced plant height at three weeks after planting, while plant stem diameter increased. Control plants had the smallest leaf length and width. The number of stomata decreased at plants derived from colchicine treated sprouted seeds and the lowest stomatal number observed was at soaking duration of 24 hours.

The experiment was conducted under field condition at Jimma University College of Agricultures and Veterinary Medicine (JUCAVM) to determine the Effects of Different Rate of Organic and Inorganic Fertilizer on Growth and yield Components of Potato (Solanum tuberosumL).The experiment design used was randomized complete block design(RCBD). The experimental treatments were replicated three times. A Potato cultivar ‘Jalene’ was grown combined with Farmyard manure and nitrogen (F0N0), (F20N70), (F0N35),(F0N70), (F20N35), (F20N0) as a treatment.. Data were recorded on Potato leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number. The result revealed that the combination of various level of Farmyard manure and nitrogen statistically (p≤0.05) affected leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number. The maximum values for leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number were recorded from (F0N70, F20N70, F0N70, F20N35, F20N0, F20N70, F20N0) respectively .However The minimum values of all the parameters were recorded from the control treatment (F0 N0). From the study it could be concluded that Potato yield components were greatly affected by different rates of organic and inorganic fertilizers. The appropriate amount of different rates of fertilizers (farmyard manure and nitrogen) should be used to increase Potato growth and yield.

Objetive: To evaluate the growth, chemical composition and quality of the silage of 45 d and 60 d cuts of Pennisetum purpureum sp. Gigante and Pennisetum purpureum cv. Taiwan grasses. Design/methodology/approximation: The study took place at the Germplasm Bank of the Rosario Izapa Experimental Field in Tuxtla Chico, Chiapas, Mexico. Chemical analysis of the silage determined crude protein (CP), crude fat (CF), crude fiber (CF), ash (A), neutral detergent fiber (NDF), acid detergent fiber (ADF), and pH. Plant height, leaf length, leaf width and stem diameter were also determined. A completely randomized design was used with three repetitions per treatment as per PROC GLM and means comparison using the Tukey procedure. Results: The CP content of both grasses decreased in the 45 d to 60 d period; from 7.18 % to 5.36 % in Taiwan grass and from 7.53 % to 6.05 % in Pennisetum sp. Gigante. Plant height, length and width of leaf, and stem diameter were greater in the Taiwan variety (P<0.05) at 30 d, 45 d and 60 d; the pH of the silage was similar in both grasses evaluated (P>0.05) at 45 d and 60 d. Study limitations /implications:  A review during low water periods is required (December-April). Findings/conclusions: Taiwan grass registered a greater growth rate in all periods; while Gigante grass showed higher nutritional value at 45 and 60 days of cutting.

The objective of this study was to evaluate the performances of three cassava genotypes on yield, physiology and morphological traits under different fertilization regimes. A field experiment was conducted in a split-plot design for two consecutive seasons in the Mansa district of the Luapula Province of Northern Zambia in the highly weathered Chromi-haplic Acrisol soils. Four fertilization regimes, control-M3, lime-M1, NPK fertilizer-M4 and NPK fertilizer + lime-M2 were the main plots, while three varieties (Mweru-V1, Bangweulu-V2 and Katobamputa (local)-V3) were subplots. Periodic measurements of leaf area index, light interception, yield and yield components from 75 days after planting (DAP) up to 410 DAP and daily weather measurements of data were recorded. Fertilization significantly increased the radiation use efficiency (RUE) and light extinction coefficient (K) in two seasons compared to the control. Significant fertilization regimes and varietal effects were observed for seasonal LAI, stem yield, root yield, biomass, harvest index (HI), tuber number, root diameter, plant height and SPAD (chlorophyll index). A significant year’s effects on root yield, yield components and physiological performances were observed while significant fertilization × variety interaction was observed on seasonal LAI, tuber number, root diameter, plant height and SPAD. Significant fertilization × year interaction effects were observed on root yield, yield components and physiological performances. Variety × year interaction was significant for seasonal LAI, stem yield, harvest index and plant height and no three-way interactions were observed on all the traits. NPK fertilizer + lime and NPK fertilizer treatments may be adopted to increase the response of cassava varietal yield, physiology and morphological traits in low soil nutrient conditions under high rain-fed conditions.
