This study was conducted at Horticultural Research Institute, at the Sindh Agriculture University Tandojam, during the period of (March 2014) the influence of pruning on fruits production of jujube. The experiment was the laid out in (RCBD) with the four replications. Hence there were total 20 plants. Four treatments were too applied T1 (pruning on 20 th May) T2 (pruning on 25 th May) T3 (pruning on 15 th June) T4 (pruning on 25 th June) and the maximum number of branch per tree (25 days to flowering) and (65 days blooming on 15 th August to 25 th on September) and the fruit weight (31.45 g) the maximum fruit size (30.50 mm2) highest sugar (6.22%) and the maximum vitamin-C contents on (130.50) Pruning in ber is required right from the year of planting. During the pre-bearing stage, it is done to build strong framework to bear the load and fruits. Pruning in Pakistan is to specific geographical location, in subtropical regions. It is done (15 th May) is most suitable pruning time to maximum fruits yield and quality in ber. The depending upon latitude while in tropical regions, depending upon the possibility of winter rainfall. In Northern Sindh like in Hyderabad, Khairpure Lahore, Faisalabad, and Bahawalpur division. It should be done before the end of May on Pruning and intensity levels of enhance the vegetative growth and fruit quality of ber.
Nitrogen (N) fertilization at optimum quantity to cultivated plants is essential for sustainable crop productivity. The experiment was conducted to evaluate the response of nitrogen fertilizers on the growth and yield traits of tomato during 2016, at the experimental field of Orchard, | department of Horticulture, Sindh Agriculture University Tandojam. Six nitrogen treatment doses were tested (T1 =control (untreated), T2 = 30 N kg ha-1, T3 = 60 N kg ha-1, T4 = 90 N kg ha-1, T5 = 120 N kg ha-1 and T6 = 150 N kg ha-1.). The data were recorded on the number of branches plant-1, days to flowering, days to fruiting, number of fruits plant-1, weight of single fruit (g), yield plot-1 and yield ha-1 (tons). The results demonstrated that N fertilization showed significant influence on both vegetative and reproductive traits of tomato. On the contrary, plants which were not fertilized with N displayed minimum values for all investigated traits. The highest N level (150 kg ha-1) showed maximum number of branches (5.51) plant-1, minimum day to flowering (42.43) less days to fruiting (46.00), more fruits plant-1 (31.00) maximum weight of single fruit (46.50 g) and highest fruit yield plot-1 (21.01 kg) and per hectare (14008 tons), respectively. It was concluded that the crop growth and productivity was significantly influenced by various levels of nitrogen. However, 150 N kg ha-1 as compared to 120 N and other concentrations considerably displayed better performance in terms of vegetative and reproductive traits of tomato. Hence for optimum growth and economically higher yield, the tomato crop may be fertilized with 150 N kg ha-1.
Salinity is one the most important constraints that limits crop production in arid and semi-arid region. Salinity influence and seed germination and it is the crucial for establishment of the plant that grow in saline soil. This research was carried out in order to test the effect of different salinity levels and growth of muskmelon, and the treatments were with different salt solutions at the, site Department of Horticulture, Garden Sindh Agriculture University Tandojam Pakistan, by the using Complete randomized design (CRD) with three replication including 4 levels of NaCl concentration (1,2,3, 4dsm-1) according to results high levels of seed germination %, number of leaves vine-1 , seedling vigor index, vine length cm, fresh shoot biomass (g) and electrolyte leakage of leaf %. It seems that the including salinity up to 1 dSm-1 improved vine length, seedling vigor index, and number of leaves vine-1 and fresh shoot biomass (g) can be used for improving performance of Muskmelon and seedling growth under saline conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
