A field experiment was conducted at the Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore, to know the effect of site specific nutrient management (SSNM) on growth and yield of groundnut. The fertilizers were applied to the crop based on uptake pattern, target yield and soil fertility status. The study indicated that application of fertilizers based on SSNM for target yield of 2.5 t ha-1 + S (10 kg ha-1) + B (10 kg ha-1) + Zn (12.50 kg ha-1) recorded significantly higher growth parameters viz., plant height (45.3 cm), number of branches (8.10), leaf area (814.95 cm-2), leaf area index (2.72) and total dry matter accumulation (31.82 g plant-1). The yield parameters viz., total number of pods per plant (19.57), pod weight per plant (12.05 g), 100 kernel weight (34.74 g) and shelling per cent (75.32) were significantly higher with the application of fertilizers based on SSNM for target yield of 2.5 t ha-1 + S + B + Zn compared to recommended dose of fertilizer. The Maximum gross returns were obtained in T4 (application of SSNM for target yield of 2.5 t ha-1 + S + B + Zn) (Rs. 79219), where as, higher net returns and B:C ratio were obtained with T3 (SSNM for target yield of 2.5 t ha-1) (Rs. 46771 and 2.47 respectively) and lower net returns and B:C ratio were with application of Rec. NPK + FYM (T1) (Rs. 33852 and 2.13 respectively).

Field experiments were conducted at the Central Research Station of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during the period from November to February in 2004-05 and 2005-06 to evaluate the effect of different levels of sulphur (0, 20, 40, 60, and 80 kg/ha) on rapeseed variety BARI Sarisha-15. Results showed that the most of the growth parameters and yield attributes were significantly influenced by different doses of sulphur. The growth parameters, yield and yield contributing characters were increased with the increasing levels of sulphur fertilizer up to 60 kg S/ha and with the doses beyond that were found to decrease. All growth parameters like plant height, leaf area, dry matter accumulation, leaf area index, crop growth rate, net assimilation rate, and relative growth rate and all yield components, such as number of siliquae per plant, seeds per siliqua, 1000-seed weight and seed yield per plant were found maximum from the treatment with 60 kg S/ha, which was at par with 80 kg S/ha. The highest seed yield (1990 and 1896 kg/ha) were found when S was used @ 60 kg/ha. The same treatment gave 24.71 % and 24.32 % higher seed yield than the control treatment, which were statistically identical with dose at 80 kg /ha of sulphur in both the years.

The integration ofAndrographis paniculataunderPinus roxburghii(Chir pine) plantation has been studied to evaluate the growth and yield for its economic viability and conservation. It was grown on three topographical aspects, namely, northern, north-western, and western, at a spacing of 30 cm × 30 cm, followed by three tillage depths, namely, minimum (0 cm), medium (up to 10 cm), and deep (up to 15 cm) tillage. The growth parameters, namely, plant height and number of branches per plant, were recorded as significantly higher on western aspect and lowest on northern aspect except for leaf area index which was found nonsignificant. However under all tillage practices all the growth parameters in both understorey and open conditions were found to be nonsignificant except for plant height which was found to be significantly highest under deep tillage and lowest under minimum tillage. The study of net returns forAndrographis paniculatarevealed that it had positive average annual returns even in understorey conditions which indicate its possible economic viability under integration of Chir pine plantations. Hence net returns can be enhanced by integratingAndrographis paniculataand this silvimedicinal system can be suggested which will help utilizing an unutilized part of land and increase total productivity from such lands besides conservation of theA. paniculata in situ.

Sustainable maize (Zea mays) production in resource challenged regions of the world is achievable among others through optimal utilisation of organic fertilisers at varying rates. Field trials were conducted in Abeokuta (Latitude 7010' N and Longitude 3015' E) in the late cropping season of 2010 and 2011. Three commercially available organic fertilisers [(Gateway 1 (GF1), Gateway 2 (GF2) and Sunshine (SF)], at three rates (0, 10 and 20 t ha-1) and three replicates were used on improved open-pollinated maize variety (Swam 1 yellow). The experiment was laid out in a randomised completely blocked design. GF1 had significantly (P < 0.05) the highest effect on growth parameters (Plant height, stem girth, leaf area and leaf area Index), with SF the least. A significant depression was observed in most growth parameters at increasing application rates of organic fertiliser, a converse pattern was observed on 1000 grain weight (GW), harvest index and cob length. A significantly higher (P < 0.05) vegetative growth, cob weight and grain yield was observed in 2010 than 2011, while 2011 had longer cobs and more 1000 GW than 2010. GF1 was recommended in Rainforest transitory zone of Nigeria at higher application rates though mediated by environmental factors. Keywords: , , ,

A field study was conducted during the Rabi season of 2009-2010 in the research field of Bangladesh Council of Scientific and Industrial Research (BCSIR), Dhaka. Six levels of GA3, viz. 0, 30, 50, 70, 90 and 110 ppm were sprayed at 18 days after sowing (DAS). GA3 treatments significantly increased plant height than the control plants. GA3 with 30 to 90 ppm significantly increased number of branches and leaves, leaf area, leaf area index (LAI), leaf dry matter and total dry matter at different growth stages. GA3 at 30 to 70 ppm gradually increased crop growth rate (CGR), net assimilation rate (NAR) and relative growth rate (RGR) and declined advanced growth stages. Number of dry pods /plant, number of seeds /pod, 1000 seed weight, fresh fodder, fresh pod, dry seed yield and harvest index also significantly increased. Positive significant correlations were found among growth parameters and as well as yield contributing characters. Asiat. Soc. Bangladesh, Sci. 43(1): 49-60, June 2017

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during October 2014 to March 2015 to study the growth and yield performance of field pea varieties as influenced by date of sowing. The experiment comprised of two factors namely, date of sowing and variety. Date of sowing comprised of 29 October, 13 November and 28 November and the variety comprised of BARI motor-1, BADC motor-1, Natore local and Narail local. The experiment was laid out in a split plot design with three replications. The results indicate that all the growth characters were varied significantly at different days after. Those growth characters except leaf area index were highest for the crop sown on 28 November. The growth characters were highest in variety Natore local and lowest in Narail local except dry matter it was lowest in BADC motor-1. The interaction effect of 28 November sowing, Natore local was highest for all of the growth parameters except leaf area index it was highest on 13 November sowing and the interaction on 29 October sowing BARI motor-1 gave the lowest value. Most of the yield contributing parameters significantly affected by sowing date. The highest seed yield (827.7 kg ha-1) and other yield contributing characters were found on early sowing (13 November) and the lowest seed yield (534 kg ha-1) and other yield contributing characters was at 28 November sowing. Variety had significant effect on yield and yield contributing parameters. The highest seed yield (1032.2 kg ha-1) and Stover yield (3221.35 kg ha-1) was obtained from Natore local while Narail local gave lowest (469.1 kg ha-1) seed yield and lowest Stover yield. The interaction of 13 November with Natore local gave the highest seed yield (1319.3 kg ha-1) and lowest seed yield was produced by Narail local (330.35 kg ha-1) by late sowing (28 November). It can be concluded that, vegetative growth were highest at 28 November sowing and yield components gave highest value on 13 November sowing. Highest yield was produced by Natore local at 13 November sowing but yield was reduced drastically when the crop sown on 28 November. So, it is clear that the optimum date of sowing for field pea is at 13 November.

Nitrogen fertilization has considerable effects on growth and yield of potato crop. Leaf expansion is one of the most important growth parameters that can be used to optimize nitrogen fertilization management in agroecological practices. We evaluated the effect of nitrogen fertilization on the leaf area index (LAI) of potato crop during different phenological stages by two different methods. Experimental plots were established in a randomized block design with the following treatments: no nitrogen supply (0-N), 133 kg N ha-1 (133-N), and 400 kg N ha-1 (400-N), using the Granola variety, at the Andes region, Merida city, Venezuela. We measured leaf area at the main phenological stages of the crop using a plant canopy analyzer. LAI showed significant differences among treatments and phenological stages, except during the emergence stage. The maximum LAI values were obtained 55 days after emergence: 400-N (1.42±0.16) > 133-N (0.92±0.21) > 0-N (0.34±0.08). Nitrogen fertilization had a significant effect on the development of LAI in potato crop along its different phenological stages.

A field experiment was conducted at the Main Research Station, University of Agricultural Sciences, Dharwad, India, on medium black soils during the kharif (wet) season of 1999. The experiment was laid out in a randomized complete block design with varying N/P ratios (0.67 to 2.00) along with a control with a constant level of potassium (60 kg ha-1). The results revealed that the number of green leaves plant-1, the dry matter accumulation in the leaves, leaf area (dm2 plant-1) and leaf area index (LAI) increased up to the flowering stage (65 DAS) and thereafter declined. In the early stages (seedling and button stages) there was no significant variation with respect to the number of green leaves plant-1 among the treatments except in the control. Similarly, leaf area and LAI did not vary at the seedling stage. Treatments receiving N/P ratios of ?1.0 or 1.0 with higher doses of nitrogen (120 kg N ha-1) gave a significantly higher number of green leaves plant-1, leaf area and LAI as compared to N/P ratios of <1.0 and the control in later stages. The dry matter accumulation in the leaves (g plant-1) differed in all the stages, but higher values were recorded in these same treatments. Thus, due to the higher number of green leaves, higher LAI and greater dry matter accumulation in the leaves, the treatments with an N/P ratio of ?1.0 or 1.0 with 120 kg N ha-1 produced higher seed yields (3188 to 3554 kg ha-1) than other N/P ratios (2761 to 3009 kg ha-1). The highest yield (3554 kg ha-1) was recorded with an N/P ratio of 1.0 in the treatment receiving 120 kg N and 120 kg P2O5 ha-1. The correlation coefficients between these photosynthetic attributes and seed yield were also positive and significant.
