ABSTRACT The semi-arid region of Northeast Brazil is vulnerable to problems of water scarcity and salinity, resulting in low-quality irrigation water and the need to adopt cultivation strategies that make the production system viable. Given the above, this study aimed to evaluate emergence, growth, and production of colored cotton subjected to increasing levels of irrigation water salinity and organic matter doses. The experiment was carried out in a eutrophic Regolithic Neosol with a sandy loam texture in a greenhouse in the municipality of Campina Grande - PB, Brazil. A randomized block design was used in a 4 x 4 factorial scheme with three replicates, and the treatments corresponded to four levels of electrical conductivity of water - ECw (1.7, 3.4, 5.1, and 6.8 dS m-1) and four doses of organic matter - OM (0, 2.5, 3.5, and 4.5% based on soil volume). Increasing irrigation water salinity with ECw values above 1.7 dS m-1 reduced emergence, growth, and production of colored cotton, and the cotton seed weight was the variable most affected by salinity. Organic matter addition led to increased cotton growth and production, especially in terms of seed weight. Increasing doses of organic matter attenuated the effect of irrigation water salinity on the number of bolls in ‘BRS Jady’ cotton.

ABSTRACT This study aimed to evaluate the water relations, cell damage percentage and growth of the castor bean cv. ‘BRS Energia’ as a function of salinity and cationic nature of the water used in irrigation. The experiment was conducted in drainage lysimeters under greenhouse conditions in eutrophic Grey Argisol of sandy loam texture. Six combinations of water salinity and cations were studied (S1 - Control; S2 - Na+, S3 - Ca2+, S4 - Na+ + Ca2+; S5 - K+ and S6 - Na+ + Ca2+ + Mg2+), in a randomized block design with four replicates. In the control (S1), plants were irrigated with 0.6 dS m-1 water, whereas the other treatments received 4.5 dS m-1 water, obtained by adding different salts, all in the chloride form. Higher relative water content in the leaf blade of plants irrigated with K+-salinized water associated with leaf succulence are indicative of tolerance of the castor bean cv. ‘BRS Energia’ to salinity. Saline stress negatively affected castor bean growth, regardless of cationic nature of water. Among the ions studied, ‘BRS Energia’ castor bean was more sensitive to the presence of sodium in the irrigation water, in terms of both water relations and leaf succulence.

The study aimed to determine the effects of different levels of phosphorous and zinc fertilizers on the yield and nutrient uptake of maize (Zea mays L.) The experiments were  conducted in a factorial experiment under Randomized Complete Block Design (RCBD) to determine the effect of P and Zn applications on TZL white composite improved variety            of maize. Four levels of phosphorus (0, 10, 20 and 30 kg P ha-1) and three levels of zinc (0, 5 and 10kg Zn ha-1) were applied on experimental plots of 4.5m x 5m replicated thrice.  The results shows no significant differences in both the  years however, highest mean values of 2327.5 kg ha-1  and 2191.5 kg ha-1 was recorded at 20 kg P ha-1 and 10 kg Zn ha-1 Application of P and Zn at different rates increases their uptake in the stover with highest values of 22.57 mg -1 kg  and 7.8 mg -1 kg  in 2018  at 30 kg Pha-1 and 18.40 mg -1 kg  and 5.21 mg -1 kg  at 20 kg Pha-1  in 2019. While 26.54 mg -1 kg and 21.85 mg -1 kg in 2018 at 10 kg Znha-1 and 6.76 mg -1 kg and 5.27 mg -1 kg in 2019 with 0 kg Znha-1 respectively. It is therefore recommended the best results of the application of 30kg P ha-1 and 10 kg Zn ha -1 should be adopted for optimum yield of maize.

Temporal and spatial variation of rainfall in semiarid regions may lead to an increase in the concentrations of salts present in irrigation water, and it is necessary to adopt techniques to reduce the negative effects of salts on plants. Thus, the present study aimed to evaluate the growth and production of colored cotton cv. BRS Topázio as a function of irrigation using water with different levels of salinity and potassium doses. The experiment was carried out in pots adapted as lysimeters under greenhouse conditions, using a non-saline Neossolo Regolítico (Entisol) of sandy texture. The experimental design was randomized blocks, with 4 replicates, with treatments distributed in a 4 x 4 factorial scheme, corresponding to four levels of saline irrigation water electrical conductivity (1.5; 3.0; 4.5 and 6.0 dS m-1) and four potassium doses (50; 75; 100 and 125% of the recommendation), with a dose of 100% corresponding to 150 mg K2O per kg-1 of soil. Irrigation using water of electrical conductivity (saline) above 1.5 dS m-1 negatively affected the growth and production of cotton cv. BRS Topázio, and cotton seed weight was the most sensitive variable. Potassium doses above 50% of the recommendation in interaction with salinity reduced the height and leaf area of cotton cv. BRS Topázio.

The experiment was carried out during the period of June to November 2013 at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh with a view to examine the yield performance of some transplant aman rice varieties as influenced by different levels of nitrogen. The experiment consisted of four varieties viz. BRRI dhan49, BRRI dhan52, BRRI dhan56, BRRI dhan57 and four levels of N viz. 0, 46, 60 and 75 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. Variety, levels of N and their interactions exerted significant influence on yield contributing characters and yield of transplant aman rice. Among the varieties, BRRI dhan52 produced the tallest plant (117.20 cm), highest number of effective tillers hill-1 (11.28), grains panicle-1 (121.5) and 1000-grain weight (23.65 g) whereas the lowest values of these parameters were produced by BRRI dhan57. Highest grain yield (5.69 t ha-1) was obtained from BRRI dhan52 followed by BRRI dhan49 (5.15 t ha-1) and the lowest one (4.25 t ha-1) was obtained from BRRI dhan57. In case of N, the tallest plant (111.70 cm), highest number of total tillers hill-1 (12.34), grains panicle-1 (133.6), 1000-grain weight (24.55 g) and grain yield (5.64 t ha-1) were obtained from 75 kg N ha-1 and the lowest values were obtained from control. BRRI dhan52 fertilized with 75 kg N ha-1 showed best performance with respect to all the parameters studied. The overall results suggest that BRRI dhan52 should be fertilized with 75 kg N ha-1 for getting higher yield under the agro-climatic condition of BAU.J. Bangladesh Agril.

This experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka during 2014-2015 to know the combined effect of different levels of sulphur (S) and boron (B) on yield and yield contributing characters, nutrient and oil content of mustard and to find out the suitable combination of sulphur (S) and boron (B) for yield maximization of mustard. There were 16 treatment combinations comprising four levels each of S (S0= 0, S1=10, S2= 20 and S3= 30 kg S ha-1) and B (B0= 0, B1= 1, B2= 2 and B3= 3 kg B ha-1). It was replicated thrice in a randomized complete block design. Results showed that the combination of S and B (20 kg S ha-1 and 3 kg B ha-1) contributed positively for better performance of yield contributing characters of mustard. The combination S2B3 (20 kg S ha-1 and 3 kg B ha-1) produced the highest grain yield (2180 kg ha-1) followed by S3B2 and S3B3 treatment combination. The highest protein and oil content of mustard were recorded from S3B3 (30 kg S ha-1 and 3 kg B ha-1) treatment followed by S2B3 treatment combination. Therefore, the combination of S and B (20 kg S ha-1 and 3 kg B ha-1) might be suitable dose for cultivation of mustard in tejgaon series soils under agro-ecological zone of 28 (Madhupur Tract) Bangladesh.Bangladesh J.
