Field trial was conducted during the 2012 and 2013 wet seasons at Institute for Agricultural Research,Ahmadu Bello University, Zaria Farms at Kadawa and Minjibir, (110 39’N, 080 20’E) and Kano (120 08’ N, 080 40’ E)500m above sea level in the Semi arid ecological zone of Nigeria, to study the influence of weed control treatment and plant population on yield and yield attributes of sweet sorghum (Sorghum bicolor (L.)Moench. sub-species. saccharatum) varieties. The treatments consisted of four levels of weed control treatment (one rate each of atrazine and primextra gold at 2.1 kg a.i/ha, hoe-weeded control at 3 and 6 weeks after sowing (WAS) and weedy check), three plant densities (53,333, 106,667, and 160,000 plants/ha), and two varieties(NTJ2 and Ex-Daura). The treatments were laid out in a split plot design with three replications. The combination of weed control treatment and the plant population were assigned to main plot while the two varieties to sub-plot. The study revealed that primextra gold at 2.1 kg a.i/haand two hoe-weeding at 3 and 6 WAS resulted in significantly longer panicle length, higher 1000-grain weight, stalk, grain, and brix yields in both seasons and locations.T he performance of this herbicide was comparable to hoeweeding in keeping the trial fields weed free and lower competition for nutrients at both location seasons. Weedy check reduced all yields and yield attributes. The 160,000 plants/ha significantly suppressed weed infestation and resulted in longer panicles, higher 1000-grain weight, stalk, grains and brix yields at the two the locations and seasons. NTJ2 performed better in term yield and yield attributes, with higher stalk yield at Kadawa and grain yield at Minjibir. Based on the result obtained from this , it can be concluded that the use of NTJ2 variety, with application of primextra gold at 2.1 kg a.i/ha, and 160,000 plant population and NTJ2 variety had resulted gave season long weed control, the highest stalk and grain yields at Kadawa and Minjibir.Keywords: Grainand stalk yields, plant population, sweet sorghum and weed control

An experiment was conducted at the Agronomy Field of Patuakhali Science and Technology University, Dumki, Patuakhali from June to December, 2013 to find out the effect of variety and planting density on the yield and yield attributing characters of local aromatic rice. The experiment was laid out in a factorial randomized complete block design with three replications, which consisted of three local aromatic rice varieties (Chinigura, Shakhorkhora and Kalizira) and four planting densities were viz. S1 (25 cm × 20 cm), S2 (20 cm × 20 cm), S3 (20 cm × 15 cm) and S4 (20 cm × 10 cm). The results revealed that the local aromatic rice var. Shakhorkhora variety produced the highest number of grains per panicle (131) and 1000-grain weight (13.8 g), consequently higher grain (2.63 t ha-1), followed by Kalizira (2.56 t ha-1) and straw yield (4.21 t ha-1). One the other hand, higher number of tillers per hill (14.8), number of grains per panicle (140 nos.) were found in 20 cm × 20 cm spacing with higher grain yield.Bangladesh J. Agril.

SUMMARYA field experiment was made with pigeon pea (Cajanus cajan (L.) Millsp.) at the Indian Agricultural Research Institute, New Delhi, during the rainy seasons of 1975 and 1976 to study the effects of plant type, plant population density and the application of phosphate fertilizer on growth and yield of pigeon pea. Cultivars BS-1 and UPAS-120 produced significantly more grain with 100 × 103 plants/ha, whereas the cultivar Prabhat produced most when 200 × 103 plants/ha were grown. Application of 13 kg P/ha increased most growth and yield attributes and increased the grain yield significantly over the control to which no P was given; however, no additional increase was obtained when 26 kg P/ha was given. The highest-yielding cultivar BS-1 benefited most from phosphate fertilizer.

To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.

In the subtropical semi-arid zones, sorghum Sorghum bicolor (L.) productivity is limited by numerous constraints. Relatively few studies have been conducted to measure the response of grain sorghum varieties to tillage and nitrogen. For sustainable crop production, selected tillage practice and fertilizer application are important. Field experiments were conducted at Al Qurna (QL), 74 km northwest Basrah province and Shatt al-Arab (SHL) and 17 km east Basrah province. A randomized complete block design, arranged in a split-split plot, was used with three replications. The tillage system was no tillage (NT), reduced tillage (RT), and conventional tillage (CT), while sorghum varieties were Inqadh, Rabih, and Cavire 2, and four levels of N fertilizer, viz., 0, 40, 80, and 120 kg ha−1. The objective of research was to evaluate two sorghum (Sorghum bicolor L.) varieties to tillage system and nitrogen (N) fertilizer. The application of tillage was shown to enhance the growth of sorghum as observed in the plant height, leaf area, number of grains panicle−1, 1000-grain weight, yield, biomass yield, and root dry matter. CT surpassed the other treatments for all studied traits. The highest value of plant height, number of grains panicle−1, grain yield, biomass yield, and root dry matter in the QL and SHL locations, respectively, were produced by Cavire 2. The plots fertilized with 120 kg N ha−1 maximize the values of plant height (132.33 cm in the SHL location), leaf area (3040.53 and 2751.47 cm2 in the QL and SHL location respectively), number of grains panicle−1 (1431.37 in the SHL location), 1000-grain weight (31.77 g in the QL location), biomass yield (15752.00 kg ha−1 in the SHL location), and root dry matter (22.42 and 20.75 g root cm−3 in the QL and SHL locations, respectively). Cavire 2 variety under CT with 80 kg N ha−1 in the QL location was the best (observed as the most promising) in terms of grain yield. Whereas Cavire 2 under CT showed best performance with 120 kg N ha−1 in the QL location in terms of biomass yield character.

A field experiment was carried out during the rainy (kharif) season of 2001 at the experimental farm of the Indian Agricultural Research Institute, New Delhi, India, to study the effect of date of transplanting and nitrogen on yield attributes, yields, nutrient accumulation and nitrogen use efficiencies in hybrid and non-hybrid aromatic rice. The experiment consisted of 9 treatments with 2 varieties (Pusa Basmati 1 and Pusa Rice Hybrid 10), 3 transplanting dates (3, 10 and 17 July, 2001) and 4 nitrogen levels (0, 60, 120 and 180 kg N ha-1). Pusa Rice Hybrid 10 had significantly higher values of yield attributes (panicles hill-1, panicle weight, spikelets panicle-1, filled grains panicle-1, 1000-grain weight), yields and nutrient accumulation than the non-hybrid Pusa Basmati 1. There were significant reductions in yield attributes, yields and nutrient accumulation after delayed transplanting. Timely transplanting on 3 July led to 8.4 and 19.1% higher grain yield than transplanting on 10 and 17 July, respectively. Successive nitrogen levels had a significant effect on yield attributes (except 1000-grain weight), yields and nutrient accumulation up to 120 kg N ha-1. The maximum grain yield (5.87 t ha-1) was recorded at the highest level of N nutrition (180 kg Nha-1) and was 4.2, 15.5 and 39.3% higher than in the 120 kg, 60 kg N ha-1 and control treatments, respectively. Pusa Rice Hybrid 10 also had significantly higher values of agronomic nitrogen use efficiency (ANUE) (12.5 kg grain kg-1 N applied), apparent nitrogen recovery (27.4%), physiological NUE (44.2 kg grain kg-1 N uptake), N harvest index (62.7%), N efficiency ratio (119.6 kg dry matter kg-1 N uptake) and physiological efficiency index of nitrogen (47.4 kg grain kg-1 N uptake) than non-hybrid Pusa Basmati 1.

Field experiments under zero-till rainfed ecosystem were conducted during 2010-11 and 2011-12 at Indian Agricultural Research Institutive New Delhi for identifying the agronomic performance, weed dynamics, nutrient uptake and profitability of clusterbean based cropping systems (clusterbean-wheat, clusterbean-mustard and clusterbean-chickpea) as influenced by three residue management practices (no residue, crop residues and Leucaena twigs) applied to both summer and winter seasonal crops. Randomized Complete Block Design with four replications were used to conduct the trials. Significantly higher green-pod yield of clusterbean (10.08 t ha-1 and 6.70 t ha-1) was recorded with the application of Leucaena twigs, followed by crop residue mulching and the least with no-residue application in 2010 and 2011, respectively. Wheat and chickpea as preceding crops produced significantly higher clusterbean green-pod yield (6.54 t ha-1 and 6.43 t ha-1) than mustard (5.18 t ha-1). The yield attributes viz. pod-clusters and weight of pods per plant showed significant variation. Significantly higher dry matter yield (299.9 g m-2) of Cyperus iria was recorded with mustard residues followed by chickpea (253.1 g m-2) and wheat (194.0 g m-2) residues. The nutrient uptake showed the same trend as that of dry pod and stalks yields and resulted significant influence due to residue management and preceding crops. Economic analysis exhibited the highest returns and net returns per Rupee invested under wheat with Leucaena twigs followed by chickpea with Leucaena twigs. Clusterbean after wheat and chickpea with Leucaena twigs was high yielding and profitable for rainfed areas under zero-till semi-arid condition.
