In order to investigate the effect of potassium application rates on growth and seed quality; we conducted a field experiment during the winter season of 2017-18, applied potassium fertilizer (SoP) @ K1: 0, K2 : 25, K3 50, K4 : 75, K5 100 and K6 125 kg K2O ha-1 to three most common local onion varieties, viz., Phulkara, Nasarpuri and Thano Bolakhan. The study was conducted at Horticultural Garden, Sindh Agriculture University Tandojam, Hyderabad. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three repeats. It was observed from the experiment that among the six potassium application rates included in the study; the potassium applied @ 100 kg K2O ha-1 (K5) remained more positively effective for seed quality traits including days to 50% bolting, flowering and maturity, flower stalk height, number of seeds umbel-1 , seed index and per hectare seed yield. Averaging overall potassium application rate treatments we found that Phulkara variety took fewer days to 50% bolting, gave more seed yield (g umbel-1) and displayed maximum seed index; whereas variety Nasarpuri took fewer days to both 50% flowering and 50% maturity, showed tallest flower stalk, gave more seeds umbel-1 and produced higher per hectare seed yield as well.

Two varieties (Anmol and Long Green) were evaluated for their yield performance on six N levels (0, 50, 75, 100, 125 and 150 kg N ha-1). The experiment was conducted in a three replicated randomized complete block design with two factorial arrangements. The results revealed that all the characters examined in this study were significantly affected by different N levels (P<0.05. The highest N level of 150 kg ha-1 produced greatest values for all the evaluated traits as compared to control. The results further demonstrated that there was a simultaneous reduction in the values of all the parameters studied under nitrogen levels of 100, 75, 50 kg ha -1 and control remained the least. Across N application rates, Bottle gourd varieties significantly varied from each other for their various parameters. As compared to Anmol, long green produced largest va...

The commercial cultivation of Gladiolus is based on natural multiplication of corms and cormels. However, multiplication rate of corms and cormels is slow and the conventional method of propagation is insufficient to meet the demand of planting material and eventually affect the final cost of corms. A number of improved conventional techniques including division of the corms, removal of leaf and flower spikes, use of standard corm size, and mechanical removal of sprouts can increase the multiplication rate of corms and cormels. These improved conventional methods of propagation are insufficient to meet the demand of planting materials. In vitro techniques are applicable for the propagation of corm producing species. These techniques are adopted at commercial level in order to fulfill supply gap of huge demand. A number of in vitro protocols have been developed for regeneration of Gladiolus plantlets using different media by using various explants sources of the plant. However, literature is rather scanty on in vitro cormel formation and acclimatization of in vitro propagules.

Germination and early growth of plants are most susceptible to salinity effect in comparison to other growth stages. In this context, the seed emergence and early vegetative growth of flowers needs to be tested properly. The pot based study was conducted in Completely Randomized Design (CRD) with three replicates at Sindh Agriculture University Tandojam. The goal of this investigation was to explore the performance of petunia plants to salt stress environment at early growth stage. Two petunia varieties (V1= Prism blue, V2= Hala lop petunia rose) were evaluated against six levels of salt stress (T1 = Canal irrigation water [Control], T2 = 3 dS m-1, T3 = 5 dS m-1, T4 = 7 dS m-1, T5 = 9 dS m-1, T6 = 11 dS m-1).The results showed that there was an inverse effect of salt stress on all the traits e...

Container-based study was conducted to evaluate the effect of seed priming and growing media on seedling rootstocks of mango. Hydropriming of seed was performed by using distilled water, while gibberellic acid (GA3) and NPK fertilizer (Solo plant) were used for hormonal and nutripriming, respectively. In second part, the primed and unprimed seeds were planted in four different growing media (GM) including GM1, GM2, GM3 and GM4. Data showed that seed germination (%), germination index (GI), seedling vigor index (SVI), height of seedling, stem diameter, chlorophyll content, electrolyte leakage of leaf, nutrient (N, P, K, Ca and Mg) contents in leaf tissue was significantly altered by both seed priming and growing media respectively. In case of priming treatments, hormonal primed seeds had the best seed germination (77.01%), stem diameter (9.65 mm) and electrolyte leakage of leaf (13.01%); while N (1.13%), P (0.14%),...

Therefore, recovery and reuse of ammonium and phosphorus is highly necessary. In recent years, many studies have been devoted to the use of different multivariate statistical analyses to investigate the interrelationship of one factor to another factor. The overall objective of this research study was to understand the significance of phosphate and ammonium recovery from biogas slurry using the multivariate statistical approach. This study was conducted using a range of salts that are commonly found in biogas slurry (ZnCl2, FeCl3, FeCl2, CuCl2, Na2CO3, and NaHCO3). Experiments with a biogas digester and aqueous solution were conducted at pH 9, with integration with NH4+, Mg2+, and PO43− molar ratios of 1.0, 1.2, and 1.8, respectively. The removal efficiency of ammonium and phosphate increased from 15.0% to 71.0% and 18.0% to 99.0%, respectively, by increasi...

Twenty genotypes of cotton (Gossypium Hirsutum L.) were screened to determine the consequence of heat stress on fibre traits.To expose the genotypes against two different thermal conditions, two sowing dates were adopted. Significant differences were observed under both conditions among the genotypes as well. The genotypes were categorized in nine groups depending on heat susceptibility index and quality parameters. Some genotypes showed significant tolerance against heat stress with good fibre traits. Cyto-178 showed low heat susceptible index (HSI)with acceptable fibre length (28.5 mm) & uniformity index (84.9 %) in the same way DAI-16 showed low HSI with good fibre strength (101tppsi) and NIAB-111 showed maximum ginning out turn (42.1 %) with low HSI.
