Field experiments were conducted at the Central Research Station of Bangladesh Agricultural Research Institute (BARI) for three consecutive years (2011-12, 2012-13 and 2013-14) to study the comparative agronomic performance and economic return of different cropping sequences for increasing cropping intensity and productivity. Three cropping patterns (CP1 - Transplanted Aman rice (var:Binadhan-7)– Mustard (var:BARISarisha-14)– Boro rice (var:BRRIdhan-28)– Transplanted Aus rice (var:Parija), CP2 - T. aman rice – Potato (var:Diamont) – Boro rice – T. aus rice and CP3 - T. aman rice – Mustard (var:BARISarisha-15) – Mungbean (var:BARIMung-6) –T. aus rice) are based on four crops; and one cropping pattern (CP4 = T. aman rice – Fallow – Boro rice – Fallow) with two rice crops as control were tested. Four crops can be grown successfully one after another in sequence in all the three cropping patterns tested. On an average organic matter 3.56, 4.70, 3.58 and 2 t ha-1 were added to soil in CP1, CP2, CP3 and CP4 by incorporation of biomass of respective crops. The highest rice equivalent yield (REY) 34.10, 34.02 and 33.36 t ha-1 was obtained from the cropping pattern CP2 in 2011-12, 2012-13 and 2013-14, respectively and it was followed by CP1 and CP3. The highest average gross return (Tk.5,00,469 ha-1) and net return (Tk. 2,63,773 ha-1) were obtained from CP2 and it was followed by CP3 but the highest average B:C ratio (2.89) was obtained from the cropping pattern CP3 followed by CP2 (2.11) due to lower cost of production than in the former one. Four crops based patterns can be recommended for higher productivity, soil enrichment & economic benefit besides creating more employment opportunity.SAARC J. Agri., 13(1): 135-147 (2015)

A field trial was conducted at the Regional Wheat Research Centre of Bangladesh Agricultural Research Institute (BARI), Rajshahi to study the comparative agronomic performance and economic return of four crops based cropping patterns. The cropping patterns were as follows: CP1= Transplanted Aman rice (cv. Binadhan-7)–Mustard (cv. BARI Sarisha14)–Boro rice (cv. BRRI dhan28) – Transplanted Aus rice (cv. Parija); CP2= T. Aman rice–Potato (cv. Diamont)–Boro rice–T.Aus rice; CP3=T. Aman rice–Mustard (cv. BARI Sarisha15)–Mungbean (cv. BARI Mung 6) –T. Aus rice and CP4 = T. Aman rice–Fallow–Boro rice–Fallow (Control). The results showed that four crops could be grown successfully one after another in a sequence in the field with three crops patterns.  The highest rice equivalent yield (REY) 25.62 t ha-1 was obtained from the cropping pattern CP2 (T. Aman rice–Potato–Boro rice–T.Aus rice) and it was followed by CP1 (18.49) and CP3 (16.03) during one year crops cycle. The highest gross margin Tk. 148882 ha-1 was also obtained from CP2  followed by CP3 (Tk. 133315 ha-1). The highest MBCR (2.24) was however, obtained from the cropping pattern CP3 (T. Aman–Mustard– Mungbean–T. Aus).  Based on overall yield performance, economic benefit and climatic situation of Rajshahi region it may be concluded that CP3 was the best pattern than others.Bangladesh Agron.

A field experiment was conducted at MLT site, Chandina under on-farm research division (OFRD), Bangladesh Agricultural Research Institute, Cumilla during 2015-16 and 2016-17 to study an economically profitable vegetable based cropping pattern in Cumilla region for increasing cropping intensity and productivity as well as to meet the vegetable demand for farm family as well as the country. The studied vegetable based cropping patterns were CP1: Red amaranth-Potato-Coriander-Indian Spinach-Ladies finger-Cauliflower and CP2: Red amaranth-Potato-Indian spinach-Ladies finger-Coriander-Red amaranth, respectively. The results showed that six vegetable crops could be grown successfully one after another in a sequence in the farmer’s field instead of two or three crops based pattern in a piece of land. From the research results it was revealed that the highest Potato equivalent yield (PEY) 226.66 t ha-1 was obtained from cropping pattern CP1: Red amaranth-Potato-Coriander-Indian Spinach-Ladies finger-Cauliflower where the lower PEY (171.38 t ha-1) in CP2: Red amaranth-Potato-Indian spinach-Ladies finger-Coriander-Red amaranth cropping pattern. From the economic analysis, it was observed that the highest gross return Tk. 22,66,600 ha-1 was obtained from cropping pattern CP1: Red amaranth-Potato-Coriander-Indian Spinach-Ladies finger-Cauliflower which leads to the highest gross margin (Tk. 18,94,542 ha-1) as well as the highest BCR (6.09) from that cropping pattern compared to CP2.

An experiment was conducted at Bangladesh Rice Research Institute (BRRI) Farm at Rangpur during July 2014 - June 2016 to introduce a 4-crops pattern with the aim of increasing cropping intensity, productivity, income and soil fertility. The experimental design was RCB with 3 replications. Four cropping patterns were tested which were: CP1 = T. Aman (BRRI dhan62)-Potato (Cardinal)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48), CP2 = T. Aman (BRRI dhan62)-Mustard (BARI Sorisha-14)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48), Farmers’ improved practice (FIP) = T. Aman (BR11)-Potato (Cardinal)-Maize (NK 40) and Farmers’ general practice (FP) = T. Aman (BR11)-Boro (BRRI dhan28)- Fallow.  In T. Aman 2014, BRRI dhan62 produced  3.87 and 3.85 t ha-1 grain yields under CP1 & CP2 (4 crops systems), respectively; BR11 gave grain yield of 4.62 and 4.36 t ha-1 in FIP and FP (3 and 2 crop system), respectively. In T. Aman 2015, BRRI dhan62 produced grain yield of 4.23 and 4.19 t ha-1 in CP1 and CP2, and BR11 gave grain yield of 5.95 and 5.92 t ha-1 in FIP and FP, respectively. After T. Aman, potato yield was 24.66 t ha-1 in CP1 and 24.17 t ha-1 in FIP during 2014-15. In CP2, 2nd crop mustard yield was 1.16 t ha-1 and3rd crop mungbean yield was only 0.98 t ha-1.In CP1, 3rd crop mungbean yield was only 0.83 t ha-1. After potato in FIP, maize yield was 8.38 t ha-1. After T. Aman (BR11) in FP, grain yield of BRRI dhan28 was 5.42 t ha-1. The yield of BRRI dhan48 in CP1 and CP2 (as 4th crop) was 4.5 t ha-1. Similar results of different crops were obtained in 2015-16. The rice equivalent yield (REY) was found to be 30.05 & 35.95 t ha-1yr-1 in CP1 during 1st and 2nd yearfollowed by FIP (23.92 & 29.82 t ha-1yr-1, respectively). The REY was higher in 2nd year compared to 1st year. In 2014-15 the highest net return of Tk.2,42,560 ha-1 was observed in CP1 followed by FIP(Tk.1,58,380 ha-1); in 2015-16, the highest net return was in CP1 (Tk.2,16,960 ha-1) followed by FIP(Tk.1,24,620 ha-1). Potato based cropping pattern was thus, the most suitable and profitable pattern in this area. T. Aman (BRRI dhan62)-Potato (Cardinal)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48) may, therefore, be the most suitable and profitable cropping pattern in medium high lands of Rangpur region. The Agriculturists 2017; 15(1) 116-126

The experiment was carried out at the research field of Agricultural Research Station, BARI, Dinajpur during Mid December to end of November for two consecutive years (2017-18 and 2018-19) to develop an economically sustainable and profitable cropping pattern over existing pattern. Three alternate cropping patterns Tomato-T. Aus-T. Aman, Tomato-Summer onion-T. Aman, Tomato-Indian Spinach-T. Aman were introduced against the existing cropping pattern Tomato–Fallow–T. Aman rice. The experiment was carried out in RCB design with three replications. The highest REY (35.91 t/ha) was recorded from the cropping pattern Tomato-Indian Spinach-T. Aman followed by Tomato-Summer onion-T. Aman (31.26 t/ha) and Tomato-T. Aus-T. Aman (29.04 t/ha). The lowest REY (24.48 t/ha) was obtained from the cropping pattern Tomato-Fallow-T. Aman (Farmers practice). The gross return and gross margin were higher in the alternate cropping patterns compared to existing cropping pattern due to additional yield of T. Aus rice, Summer Onion and Indian Spinach. Therefore, farmers in Dinajpur region of Bangladesh could follow alternate cropping pattern in their medium high land where lands remain fallow after harvesting of Tomato for higher crop productivity and profitability.

Field experiments were conducted from 2015-16 to 2017-18 on a Typic Rhodustalfs (Alfisol) soils of Telangana at Regional Agricultural Research Station, Palem, Nagarkurnool, Southern Telangana Zone, India to validate targeted yield based fertilizer prescription equations which developed for hybrid castor by adopting eight treatments viz., Blanket recommendation (100% RDF:80:40:30 kg N, P2O5 and K2O ha-1), Blanket+5 t ha-1 of vermin-compost (VC), STCR-Target yield with NPK alone at 25q ha-1, STCR-Target yield with IPNS at 25q ha-1, STCR-Target yield with NPK alone at 30q ha-1, STCR-Target yield with IPNS at 30q ha-1, Farmer’s practice (40:20:0kg N, P2O5 and K2O ha-1) and Absolute control (without inorganic and organic fertilizers). The findings of these test verification trials clearly revealed that the percent achievement of the aimed yield target was within + 10 percent variation confirming the validity of the equations. Using STCR-NPK@25 and 30q ha-1 recorded significantly higher seed (20.74 and 22.30q ha-1) and stalk (24.63 and 26.36q ha-1) yield over blanket recommendation (19.40 and 23.13 q ha-1), while STCR-IPNS at 25 and 30 q ha-1recorde relatively higher seed (20.98 and 22.69q ha-1) and stalk (25.88 and 27.13q ha-1) yield over STCR-NPK alone treatments. The magnitude of built-up was higher with STCR-IPNS treatments as compared to STCR-NPK alone, blanket recommendations, farmer’s practice and absolute control.

A relevant improvement of the cultivar conditions of Rosmarinus officinalis L. in desert areas was achieved by a specific combination between irrigation system and soil conditioner. A drastic reduction of water employment was obtained without affect the quality of the plants, determined by monitoring growth parameters and essential oil characteristics. In particular, the effect of surface and subsurface drip irrigation systems and different soil conditioners on growth parameters, yield, and essential oil constituents of rosemary plant was assessed. Field experiments at the Agricultural Research Station (Al-Adlya farm), SEKEM group Company, El-Sharkiya Governorate, Egypt, conducted over the two seasons revealed the effectiveness of the subsurface irrigation system in obtaining better performances, especially in terms of water saving. The combination of subsurface irrigation and the conditioner Hundz soil with bentonite showed the maximum mean values of growth characters compared with other soil amendments during both seasons. The possibility to employ a water-saving irrigation system as the subsurface one without any drawback in the resulting plants was also explored in terms of molecular composition. GC-MS analysis of the essential oil extracted from plants growth under different irrigation conditions revealed a comparable composition in both cases. The goodness of the most performing system was also confirmed by the comparable yield of the essential oil.

Aim: To find out the optimum harvesting stage of high yielding rapeseed-mustard varieties to fit in rice based cropping pattern. Study Design: The field study was arranged following RCB (factorial) design with three replications. Place and Duration of the Study: Agronomy field of Regional Agricultural Research Station, Jamalpur (located between 24°34ʹ and 25°26ʹ North latitude and 89°40ʹ and 90°12ʹ East longitude), Bangladesh during 2015-2016 and 2016-2017. Methodology: Seeds of mustard varieties viz. BARI Sarisha-11, BARI Sarisha-14, BARI Sarisha-15, Binasarisha-4 & Tori-7 were sown in line maintaining 30cm spacing on 02 November, 2015 and 06 November, 2016. This varieties were harvested at four different harvesting stages viz. H1= Green stage of siliquae, H2= Pale yellow stage of siliquae, H3= Golden yellow stage of siliquae and H4= Full maturity stage of siliquae. Green stage of siliquae was determined just at seven to ten days after all flower droppings of crop while the pale and golden yellow stage of siliquae was determined when 40%-50% and 70%-80% bearing turned into light yellow and deep yellow in color respectively. Full maturity stage of siliqua was determined when lower bearing just brust out. Results: BARI Sarisha-14, BARI Sarisha-15 (B. campestris) and Binasarisha 4 (B. napus) may be harvested at pale yellow stage of siliquae at 73, 82 and 78 DAS (average of two years) considering 11.0% seed and 3.15% oil yield; 10.0% seed and 1.56% oil yield; 6.60% seed and 3.90% oil yield loss respectively than full maturity stage of siliquae. Conclusion: BARI Sarisha-14, BARI Sarisha-15 and Binasarisha 4 need to be sown within first week of November in districts named Mymensingh (located 24°15′ and 25°15′ N and 90°49′ E longitudes),  Jamalpur (located 24°34ʹ and 25°26ʹN latitude and 89°40ʹ and 90°12ʹ E longitude) and Tangail (located 24°01′ and 24°47′ N latitudes and 89°44′ and 90°18' E longitudes) and the crop should be harvested at pale yellow stage of siliquae (within 73-82 days period) sacrificing seed and oil yield loss to some extent to introduce HYVs of rapeseed-mustard in rice based cropping pattern.
