A field trial was conducted in 2016-2017 at Vegetable Seed Production Farm, Punjab Agricultural University, Ludhiana in randomized complete block design with three doses of nitrogen (125, 150 and 175 kg/ha) and four summer season vegetables (capsicum, chilli, cucumber and tomato) as intercrops replicated thrice. The maximum plant height (57.11 cm), number of leaves per plant (15.85), leaf size (394.87 cm2), leaf area index (3.39), plant spread (64 cm), head weight (176.72 g), number of axillary sprouts per plant (9.01), weight of axillary sprouts per plant (130.50 g) and total yield (145.47 q/ha) obtained with nitrogen @ 175 kg/ha were statistically at par with nitrogen @ 150 kg/ha. The statistical differences were found to be non-significant in intercropping systems but the sole crop of broccoli showed maximum values for growth and yield parameters. The highest benefit cost ratio (BCR: 3.74) and land equivalent ratio (LER: 1.67) were observed in broccoli + tomato followed by broccoli + chilli.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

A field experiment was carried out to study the effects of inorganic nitrogenous fertilizer and organic cowdung manure on growth and yield of carrot. Three different levels of urea along with three different levels of cowdung were employed in the investigation following randomized complete block design. The result revealed that the application of 150 kg N ha-1 as urea was found suitable for maximum gross and marketable yield (47.35 t ha-1 and 39.0 t ha-1, respectively), while 15 t cowdung ha-1 showed better gross and marketable yield (38.13 t ha-1 and 30.42 t ha-1 , respectively). Regarding the combined effect, the combination of 150 kg N ha-1 and 15 t cowdung ha-1 resulted in the best performance in gross and marketable yields (51.22 t ha-1 and 43.41 t ha-1, respectively). The net return (TK. 211142 ha-1) and benefit cost ratio (4.61) were maximum in the treatment combination of 150 kg N ha-1 in the form of urea and 15 t cowdung ha-1.DOI: http://dx.doi.org/10.3329/jbau.v10i1.12012J.

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

Cotton crop is an important, cash and fiber crop of Pakistan. Its raw material and other products are exported to other countries. Horse purslane is one of major weed responsible for yield reduction. Research trial was carried out at MNS University of Agriculture Multan during Kharif, 2018 to compare the effect of horse purslane on cotton growth and yield. The study was conducted using the Randomized Complete Block Design with three replications. The treatments were; plots maintained horse purslane free for whole season, for 30 days after sowing (DAS) and for 60 DAS, horse purslane and other weeds free for whole season, for 30 DAS and for 60 DAS, weedy check (containing horse purslane only), weedy check (containing all weeds except the horse purslane) and weedy check (all weeds including horse purslane). Weed density and dry bimass, crop growth and yield related parameters were recorded following standard procedures. Horse purslane reduced the height of cotton plants by 26.51%, crop growth rate by 28.44%, total dry matter 28.46% and lint yield by 45%. Treatment having horse purslane and other weeds free for whole season performed best in experiment. Highest benefit cost ratio (1.70) was observed for plots that were kept free from horse purslane and other weeds till 60 DAS.

Sugarcane is an important cash-cum-industrial crop of Bangladesh and mainly cultivated in north-western part of the country where different intercropping systems are available. The experiment was carried out at the Bangladesh Sugarcane Research Institute (BSRI) farm, Ishurdi, Pabna, Bangladesh in two successive years viz. 2008–2009 and 2009–2010 to investigate the profitability of sugarcane (cv. Isd 37) with potato (cv. Cardinal) and mungbean (cv. BINA mung5) as successive intercrops. Two factors included in the experiment viz. Factor A: Row to row distance of sugarcane such as 80 cm (S1), 100 cm (S2) and 120 cm (S3) where potato and Mungbean were intercropped. Factor B: Cutting of sugarcane leaf such as cutting of leaves (C1) and No cutting of leaves (C2). The experiment was laid out following randomize complete block design. For sugarcane cultivation BSRI technique and for intercropping the cultivation systems indicated by Bangladesh Agricultural Research Institute were followed. The cane yield and sugar yield were the highest at 100 cm row to row spacing (RRS) of sugarcane (non-leaf cutting = C0) intercropped with 2 rows (2R) of potato followed by 2R of mungbean (S2C0). The lowest yield of sugarcane was found at 80 RRS (C0) with one row (1R) of potato and 1R of mungbean (S1C0). The effect of light interception on growth and yield of first intercrop (potato) was insignificant but significant for second intercrop. The highest yield of potato tuber was 15.28 t ha–1 in S5 (sole potato) followed by 10.85 t ha–1 in S3C1 (sugarcane under leaf cutting at RRS 120 cm with 3R of potato followed by 3R of mungbean). For the yield of mungbean (2nd intercrop), light interception ratio (%) was significantly lowest in (S3C1) where sugarcane RRS was 120 cm with 3R of potato followed by 3R of mungbean under leaf non-cutting (C0) of sugarcane. The highest adjusted cane yield (170.66 t ha–1), benefit cost ratio (3.49) and LER (2.33) were observed in sugarcane at RRS 120 cm with 3R of potato followed by 3R of mungbean (S3C1). Results of both years indicated that intercrops gave higher land equivalent ratio and net return over sole sugarcane planted while sole sugarcane gave maximum benefit cost ratio compared with other intercrops. Finally, on the basis of results it may be concluded that sugarcane transplanted at RRS at 120 cm with 3R potato followed by 3R of mungbean can be grown as intercrops for higher economic return. J.

A field experiment was conducted at S.V. Agricultural College farm (ANGRAU), Tirupati, India during rabi, 2009-10. The experiment was consisted of five system treatments (sole maize at 60 x 20 cm sowing, sole maize in skipped row sowing, maize in skipped row + greengram, maize in skipped row + blackgram and maize in skipped row + cluster bean) and three nitrogen doses (100, 75 and 50% recommended dose of nitrogen). The treatment combinations were laid out in factorial randomized block design with three replications. Yield attributes and grain yield of maize were maximum with sole maize at 60x20cm spacing but at par with maize + cluster bean, maize + blackgram and maize + greengram intercropping system. The lowest parameters were observed with sole maize sown in skipped rows. All the parameters were maximum with the application of 100% recommended dose of nitrogen to maize, but comparable with that of 75%. The maize equivalent yield, land equivalent ratio and benefit cost ratio were higher with maize + cluster bean intercropping as compared to other treatments. The result revealed that among the different maize intercropping systems tested, maize in skipped rows + cluster bean with 75% recommended dose of nitrogen to maize was found economically profitable.SAARC J.

The experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period of November 2019 – May 2020 to find out Influence of bio-fertilizer application method with organic and in-organic fertilizer on growth and yield of bitter-gourd in winter season .The experiment was consisted of two factors : as- Factor A: Fertilizer (4 levels) T0: control, no fertilizer ,T1: Organic (kitchen compost @1000 kg/ha),T2: in-organic (N46 P40 K 45 ) Kg/ha and T3: Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha Factors B: Bio-fertilizer application method (3 levels) F1: Seed treatment with bio-fertilizer @ 100ml/250g seed,F2: Seedling treatment with bio-fertilizer @400 ml/500 seedling. And F3: Soil treatment with bio-fertilizer @.046 g/m2. The two factorial experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Maximum plant height (299.69 cm),fruit number per plant (19.96), fruit length(27.11 cm), yield/plant (1.05 kg), yield per plot(6.30kg) and total yield (19.44 t/ha) were found from T3F3 treatment. whereas minimum plant height (90.67 cm), fruit number per plant (1.27), fruit length (4.49 cm), yield/plant (.046 kg), yield per plot(.28 kg) and total yield (.86 t/ha) were found from T0F2(control) treatment .All growth related parameter was collected up to 75 DAS due to COVID-19.This study suggests that T3F3 (Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha)+ bio-fertilizer (soil treatment) treatment acts as a potential source of plant nutrients for suitable bitter gourd production. The combination of organic, In-organic and soil application of bio-fertilizer (T3F3) gave the highest gross return (Tk. 1458000). The lowest gross return (Tk.85600) was obtained in the control condition where no bio-fertilizer as well as no fertilizer was applied. The combination of organic, inorganic and soil application of bio-fertilizer (T3F3) gave highest benefit cost ratio (3.16) and the lowest benefit cost ratio (0.60) was obtained in combination of control condition (T0F2). So, the economic analysis revealed that the treatment T3F3 combination appeared to be the best for achieving the higher growth, yield and economic benefit of bitter gourd.

A field experiment was conducted to investigate the effect of different planting time on the growth and yield of cauliflower (Brassica oleracea var. botrytis) at the Germplasm Centre of Agrotechnology Discipline, Khulna University, Khulna, from September, 2016 to March, 2017. There were four planting times included in the experiment viz., T1: 15 October, T2: 15 November, T3: 15 December, and T4: 15 January. Data were collected on plant height (cm), number of leaves per plant, leaf length and breadth (cm), curd size (cm), individual plant weight (kg) and yield (t/ha). The tallest plant (81.20 cm), maximum number of leaves (23.60), leaf length (64.40 cm), leaf breadth (24.60 cm) and also curd length (19.80 cm) and breadth (18.00 cm) were recorded from the treatment T2 (November planting). The economic (67.08 t/ha) and biological yield (87.88 t/ha) were also found to be the highest in the treatment T2 (November planting) followed by the highest benefit cost ratio (2.15). Therefore, the planting of cauliflower could be done during November in Khulna region to ensure better growth and yield with better economic return. South Asian J. Agric., 7(1&2): 25-29
