Seasonal abundance, distribution and pest severity of white fly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) were studied on the chili (Capsicum spp.) varieties namely BARI Morich 1, BARI Morich 2, BARI Morich 3, BINA Morich 1 and Bogura Morich during November 2017 to June 2018 at Gazipur in Bangladesh. Results showed that the white fly started to build up their population from 2nd week of February on the chili varieties and exerted the peak abundance at the last week of February when the plants were at flowering stage. Abundances of white fly positively correlated with maximum temperature and relative humidity, and negatively correlated with minimum temperature and rainfall. Meteorological parameters predicted 11.6 to 32.9% abundance of whitefly on the chili varieties. Occurrence of white fly on different strata of the varieties was statistically low on BARI Morich 2 compared to other varieties. Virus infection levels among the varieties differed significantly and BARI Morich 2 showed the lowest level of infection. BARI Morich 2, Bogura Morich and BARI Morich 1 revealed low level of leaf curl indices (6.8 to 9.3%) and these varieties could be selected for cultivation in the areas where whitefly is a major pest of chili.

The effect of different treatment schedules of Novaluron 5.25% + Indoxacarb 4.5% SC against pod borer of pigeon pea gave superlative effect over the sole insecticide Novaluron & Indoxacarb & standard check Lamda-cyhalothrin; though, all the treated plots with chemicals were significantly superior in their performance over that of control plots. Among the three selected dose of Novaluron 5.25% + Indoxacarb 4.5% SC (750, 825, 875 ml ha<sup>–1</sup>); the said chemical @ 875 ml ha<sup>–1</sup> was recorded as best in managing <italic>Helicoverpa armigera</italic> population up to harvesting period (mean 0.03% infested pod of both years), while, @ 825 ml ha<sup>–1</sup> also recorded remarkable effect on the target pest. The maximum yield (23.40 q ha<sup>–1</sup>) was obtained from the plots treated with Novaluron 5.25% + Indoxacarb 4.5% SC @ 875 ml ha<sup>–1</sup> closely followed by @ 825 ml ha<sup>–1</sup> (22.98 q ha<sup>–1</sup>). The yield increase was also of high order. Highest cost-benefit ratio (2.07) was recorded in Novaluron 5.25% + Indoxacarb 4.5% SC @ 825 ml ha<sup>–1</sup> closely followed by @ 875 ml ha<sup>–1</sup>.

The Impact

Two field experiments were conducted at the Lajas and Juana Díaz Agricultural Experiment Substations to evaluate seven pigeon pea [Cajanus cajan (L.) Huth] cultivars for yields, weed suppression, and the impact on the subsequent tomato [Lycopersicon lycopersicum (L.) Karst, ex Farw] and pepper (Capsicum annuum L.) plantings. Trials started ¡n July 1993 and ended in June 1995. Treatments consisted of incorporation of plant stubble from seven different pigeon pea cultivars into the soil. Cultivars Kaki, 2B-Bushy, PR 147, Blanco de Yauco, Guerrero, Cortada, and Line 84 were grown from mid-July to late January of the following year. Tomato and pepper seedlings were transplanted into the plots six weeks after incorporation of whole plant stubble of pigeon pea. Pod yields of all cultivars, except Guerrero, were higher in Juana Díaz than those of Lajas. Compared with control plots, pigeon pea did not affect weed densities at Lajas, but at Juana Díaz all cultivars reduced weed densities in tomato and pepper grown in 1994 and 1995. The weed species suppressed by pigeon pea in the tomato planting at Juana Díaz were Amaranthus dubius Mart, ex Thell, Cyperus rotundus L., Echinochloa colona (L.) Link, and Trianthema portulacastrum L.

Abstract: The present study was done impact of agricultural wastes on growth and production by oyster mushrooms i.e., Pleurotus florida which have a rich source of protein and also has important medicinal properties. The yield and Biological efficiency of different lignocellulosic agricultural wastes viz. Wheat straw, Maize leaves, Cob leaves, Jawar residue, Bajra residue, Bamboo leaves, Paddy straw, Sugarcane, Cotton, Soyabean, Safflower (Pods residue), Pigeon pea (Pods residue), Mung bean (Pods residue), Cowpea (Pods residue). the paddy straw showed the highest yield 892.25 gm with the highest biological efficiency 89.09 % followed by Cowpea pods residue gives 879.65 gm yield of Pleurotus florida and shows biological efficiency of 87.72%, followed by Wheat straw substrate showed 871.18 gm yields with 87.27 % biological efficiency. The Pigeon pea pod residue showed 865.85 gm yield during three harvestings having 86.36% biological efficiency. Similar result was seen Bajra residue and soybean pod residue in bajra residue showed 792.45gm yield during three harvestings having 79.245% biological efficiency, in soybean pod residue showed 791.63 gm yield during three harvestings having 79.163 % biological efficiency. The lowest yield was seen in Bamboo leaves and cotton residues. In cotton residue substrate 433.22 gm total yield along with 43.32% biological efficiency, Bamboo leaves substrate total yield were seen 438.12gm with 43.81 % biological efficacy.
