Integrated weed management (IWM) is recommended to reduce our reliance on synthetic herbicides and sustainable maize production. In this study, different tillage regimes and various allelopathic treatments were integrated for weed management in spring planted maize at Agricultural Research Station, Swabi (KP), Pakistan during spring both years 2014 and 2015. The experiment was laid out at silt loam soil in Randomized Complete Block Design (RCBD) with a split plot arrangement having three (03) replications. Different tillage regimes namely minimum, conventional, and deep tillage regimes were assigned to main plots (Factor A) and various allelopathic plants [Sorghum {Sorghum bicolor (L.) Conard Moench.}, Sunflower (Helianthus annuus L.) and Parthenium (Parthenium hysterophorus L.)] residues as surface mulches and their water extracts integrated @ 15L each +atrazine @ 0.125 kg a.i ha-1 (1/4 th of the recommended dose) was assigned to sub plots (Factor B). Data were recorded and analyzed for dry biomass (g) of total weeds 60 DAS, leaf area (cm 2), leaf area Index (%) and Stover yield (Kg.ha-1). Integration of tillage regimes and various allelopathic treatments had significant effect on tested parameters. However, the efficacy of surface mulches was more pronounced than atrazine foliar application @ 0.50 kg a.i ha-1 and allelopathic plants water extracts combined with atrazine @ 0.125 kg a.i ha-1. Data obtained for the interaction effect (tillage x weed control treatments) showed that maximum stover yield of 12426 kg.ha-1 was recorded in sorghum +sunflower + parthenium (S.M) each @ 6 Mg ha-1 at 3-4 leaf stage of maize under conventional tillage regime. Hence it could be considered as an alternative to atrazine @ 0.50 kg a.i ha-1 (recommended dose) for weed management in spring planted maize. However, further studies are suggested to investigate the phytotoxic effect of these plants' residues on soil microbial activities.

It ranked 2 nd after apple in the world business and largely produced in Pakistan. Allspecies of citrus aresubtropical fruitsprimarily, but are suitable for a wideclimaterange, 28-124 °F. Sweet Orange is an important member of genus "citrus" (Nicolosi et al., 2000). In Pakistan, citrus fruits are cultivated on 194.5 thousand hectaresarea , with a production of 1982.25 thousand tons per year, while citrus is grown on 4.0 thousand hectares in KPK is with 32.3 thousand tons per year production (MINFA, 2010). Technique of hot water treatment is applied to many fruit types to prevent insect and fungal attack in the post-harvest management (Lurie, 1998). Hot water (HW) and steam or hot air is applied commercially for increasing storage life of fruits. Heat treatment methods and duration of fruit exposure to heat may affect fruit quality. Hot water treatment is more effective than the hot air and is a heat transfer medium Abstract | The experiment "Influence of hot water treatments on the storage life of sweet orange (Citrus sinensis) cv. Sherkhana-I" was carried out at

The experiment was conducted in randomized complete block design (RCBD) with split plot arrangement and replicated three times at Horticulture Nursery of Agriculture University, Peshawar, Pakistan in 2016. Sowing dates (25 th October, 9 th and 24 th November) were assigned to main plot, while umbel pinching levels; secondary + tertiary + quaternary (STQ), primary + tertiary + quaternary (PTQ) and tertiary and quaternary (TQ) umbel pinching were allotted to sub plots. Maximum (p<0.05) days to flowering (111 days), plant height (137.5 cm), days to seed setting (15.6 days), umbel diameter (14.6 cm), days to maturity (151 days), variability in harvest time (34.8 days), seed yield umbel-1 (5.1 g), seed yield plant-1 (34.2 g) and seed yield tha-1 (3.7 t ha-1) were recorded on 25 th October sowing date. Umbel pinching had significantly enhanced plant height (136.4cm), umbel diameter (17 cm), and seed yield umbel-1 (5.7 g) by pinching of STQ umbels. While, maximum seed yield plant-1 (46.9 g), seed yield t ha-1 (5 t ha-1) and variability in harvest time (34.1 days) were observed in TQ umbel pinching. Interaction between sowing dates and umbel pinching (S x U) were found significant in case of seed yield umbel-1 , seed yield plant-1 , seed yield t ha-1 and variability in harvest time. Based on the present findings it is concluded that sowing on 25 th October with pinching of TQ umbels is recommended for maximum seed production in carrot.

Current experiment was conducted in Randomized Complete Block Design with split plot arrangements and three times replicated. Organic regime (Farm Yard Manure, Spent Mushroom Compost and Poultry Manure at 25:10:5 tons ha-1) and Inorganic regime (N:100, P:50, K:50 kg ha-1) were assigned to the main plots while brinjal cultivars (Namli-F1, Black Boy-F1, BSS-513 and Meiyinqienquan) were subjected to the subplots. Data on various quantitative and qualitative variables of eggplant cultivars were taken under both the regimes. Results revealed that both cultivars and growing regimes significantly (p≤0.05) affected the performance of eggplant. Among eggplant cultivars, more number of leaves, fruits, fruit weight plant-1 and total yield were observed in cultivar Namli-F1 followed by Black boy-F1 which also gave maximum total soluble solids. Highest plant height and fruit dry matter contents were noted in cultivar BSS-513. However, the performance of cultivar Meiyinqienquan was inferior among all the cultivars except for the number of days to 50% flowering. Regarding growing regimes, it was noticed that under the organic regime maximum plant height, number of fruits, fruit weight plant-1 , total yield and total soluble solids were produced. Whereas, maximum number of leaves plant-1 and chlorophyll content were produce under the inorganic regime. Present investigations concluded that cultivar Namli-F1 should be grown for the promising yield while Black boy-F1 and BSS-513 for their better quality under the organic regime.

Above and below the optimum level vegetative as well as the reproductive growth negatively affected therefore the experiment was designed to evaluate the response of brinjal cultivars to various levels (0, 70, 100, and 130 kg ha-1) of nitrogen in the year of 2014. All the treatments were randomly assigned with split plot arrangement with three replicates. Nitrogen levels were considered as main plot treatments and brinjal cultivars (Shamli, Black Long, Purple Long) as subplot treatments. Both cultivars and nitrogen levels showed significant difference among growth parameters. Plant height, days to flowering, days to fruiting, number of leaves plant-1 , number of fruits plant-1 , fruit weight, total yield and survival percentage were significantly increased by nitrogen levels. Maximum plant height (138.22 cm), number of leaves plant-1 (434.44), days to fruiting (64),days to flowering (39),fruit weight (74.50 g), number of fruits plant-1 (16.37), total yield (13.72 t ha-1) and survival percentage (98.50%) were observed in plots received nitrogen at 130 kg ha-1 , however, control plots were recorded with the lowest survival percentage. Among cultivars, maximum plant height (120.83cm),days to flowering (38), days to fruiting (54), number of leaves plant-1 (349.17), fruit weight (72.42g), total fruits plant-1 (15.37), total yield (13.26 t ha-1) and survival percentage (95.38%), were recorded in cultivar Purple Long, while minimum values for these parameters were recorded in cultivar Black long. It is concluded from the results that cultivar Purple Long with 130kg N ha-1 showed better results regarding growth and yield; hence it is recommended to cultivate mentioned cultivar under the agro climatic condition of Peshawar for optimum growth and yield.
