Pleurotus ostreatus, an edible mushroom is an essential food product. Recognised as one of the cheapest sources of proteins, their high nutritional and anti-nutritional properties are of immense importance to humans. The present study evaluated the effect of sawdust and dried plantain leaves on the growth and yield of Pleurotus ostreatus. Sawdust and dried plantain leaves were composted into seven substrates; as single substrates and at different combinations. The composted substrates include sawdust 100 % (M0), Dry plantain leaves 100% (M1), Dry plantain leaves + sawdust at the ratio of 1:4 (M2), 2:3 (M3), 3:2 (M4), 1:1 (M5) and 4:1(M6). Growth parameters of interest assessed flush include mycelia running rate (MRR), area of pileus, length of the stipe, the girth of the stipe, fresh weight and dry weight, number of fruit body, total yield and biological efficiency. At the end of the three weeks spawn running period, M0 was overall best in supporting mycelia running rate with a mean MRR of 16.00 cm. M1 substrates produced mushroom with longer and bigger stipes (7.17 cm) at the first flush. A higher number of fruit bodies (82.66), total yield (130.35 g), and biological efficiency (43.45 g) were all seen in M0 substrates. Sawdust at 100 % (M0) proved to be the best substrate for the cultivation of Pleurotus ostreatus.

Four organic substrates; Mahogany Sawdust (MSD), Corn Cobs (CC), Oil Palm Fruit Fibre (OPFF) and Rice Bran (RB) were evaluated for their effects on growth and yield of Pleurotus ostreatus (Jacq.Fr.) Kumm. The completely randomized experimental design was adopted for the study with 4 treatments replicated 10 times. Results on mean number of days for spawn run, primordial formation and formation of fruit body were 19.90±0.28(CC)-25.20±0.29(MSD), 45.10±0.28(CC)-47.90±0.23(MSD) and 56.50±0.22(CC)-59.40±0.27(MSD), respectively. Similarly, height of stipe, diameter of stipe and diameter of pileus ranges were 3.28±0.13 (MSD)-3.51±0.06 (RB),1.26±0.06 (OPFF)-1.39±0.05(RB) and 4.08±0.05(CC)-4.70±0.04(OPFF), respectively. Fresh weights (g), dry weights (g) and biological efficiency were 10.20±0.31(OPFF)-11.05±0.14(MSD), 3.18±0.15(CC)-3.38±0.13(RB) and 4.14±0.14 (OPPF)-4.42±0.06(MSD), respectively. Results on mushroom growth showed that CC took the least duration for full mycelial colonization and the longest duration occurred on MSD. There were significant differences (P ≤ 0.05) between the durations required for primordia formation among the four organic substrates. The results on mushroom yield showed that mean fresh weights of harvested mushrooms varied from 10.20±0.31 g on OPFF to 11.05±0.14 g on MSD. There were no significant differences (P ≥ 0.05) in the biological efficiency of mushrooms grown on MSD, CC and OPFF substrates. Considering the growth and yield attributes RB was observed to be the best substrate and could be used for commercial production of P. ostreatus among the various organic substrates used in this study.

Abstract Rice plants (Oryza sativa) are a significant food crop. Tobacco plants (Nicotiana tabacum) can be beneficial and affect growth due to allelochemical content. The srudy aims to determine the effect of tobacco extract (N. tabacum) on the growth and yield of rice (O. sativa) Inpari-32 variety. The study method used the RBD as an experimental design. Three treatments with different concentrations of tobacco extract and one control with three replications. Growth variables were observed: growth rate, plant height, number of tillers, number of leaves, shoot and root dry weight, flowering age, and phytohormones. Observations of the harvest stage include the weight of stover, number of panicle seeds, the total number of tillers, weight of 1000 seeds, the ratio of the weight of filled grain, and productivity (tons/ha). The results showed that although not significant, tobacco extract treatment increased the number of tillers and leaves, the content of phytohormon IAA in the vegetative phase, the content of GA3 in the generative phase, shoot-root ratio, number of tillers, and accelerated flowering age. The implication of tobacco extract positively affects the plant growth variable and accelerated flowering age of rice variety (O. sativa) Inpari 32.

Fertilizer Rates

Zingiber zerumbet (L.) Smith, known as Lempoyang in Malaysia, belongs to the family Zingiberaceae. Previous studies on Lempoyang mainly focused on the chemical properties and biological activities of the rhizome extracts of this plant. Despite the tremendous demand for the rhizomes of Z. zerumbet, there is a lack of information on cultivation practices and a scarcity of planting materials. By using the pre-soaked technique, the challenges posed by Z. zerumbet dormancy can be overcome, obtaining good quality and uniform planting material throughout the year. Besides that, it is also crucial to determine the optimum shade level and NPK fertilizer rates to obtain a high yield and good quality rhizomes of Lempoyang. Six concentrations of 6-benzylaminopurine (BAP, 0, 50, 100, 150, 200, and 250 mg/L) and ethephon (0, 150, 300, 450, 600, and 750 mg/L) were tested to evaluate their effects on breaking rhizome dormancy. Three different shade levels (full sun, 30%, and 50% shade levels) and four combinations of Nitrogen (N), phosphorus (P), and potassium (K) (NPK) fertilizer at different rates were evaluated to study their effects on plant growth and yield performance. The results showed that BAP at 100 mg/L and ethephon at 300 mg/L performed better than the other compound concentrations tested in promoting the breaking of bud dormancy. A significant interaction effect was observed between shade levels and NPK fertilizer rates in all the growth parameters examined, except for the number of tillers per plant. Plants grown under 30% shade with NPK 4 produced the highest rhizome fresh weight, dry weight, and yield, but plants grown under 50% shade with NPK 4 showed the highest plant height and number of tillers per plant.

The reactions of five commercial varieties of okra, <i>Abelmoschus esculentus</i>, to <i>A. gossypii</i> were evaluated under semiarid field conditions. Each experimental plant of varieties Clemson spineless, Clemson spineless 80, Lee, Perkins dwarf, and Local was infested 60 days after emergence by three late-nymphal instars of the aphid. The results showed that aphid populations increased constantly on the varieties, except for days 42 and 49 after infestation, attaining a peak at about the end of the growing season. Differences in aphid densities were recorded between varieties. The aphids were most numerous on var. Local, while lowest in number on var. Lee. Infestation by aphids on okra varieties reduced yield by 57% on var. Perkins dwarf, 56% on var. Lee, 24% on var. Clemson spineless, 21% on var. Clemson spineless 80, and 5% on var. Local. Reduction in the number of pods produced per plant followed the same pattern as observed for total yield. Aphids had not altered significantly the vegetative plant growth at day 37 following infestation. At day 66, a substantial decrease in shoot fresh and dry weights and also leaf area was evident on var. Perkins dwarf while on var. Clemson spineless only the leaf area was significantly reduced. Moreover, aphid-free controls varied widely in their growth and productivity at the end of growing season. Varieties Clemson spineless and Clemson spineless 80 produced the highest total yield and pod numbers, var. Local the lowest. The varieties Perkins dwarf and Clemson spineless produced significantly higher shoot fresh and dry weight, as well as leaf area, than vars. Lee and Local.

Mushroom cultivation has continued to receive growing attention because of its nutritional and medicinal values. However, this study examined the effect of hardwood sawdust on the growth of Pleurotus ostreatus and Pleurotus pulmonarius were investigated. Relationship between fungal incidence of the substrates (sawdust) and that of the mushroom were examined. Both Pleurotus ostreatus and Pleurotus pulmonarius were inoculated on fermented and unfermented sawdust of Tectonal grandis and Celtis zenkeri. The fruiting bodies of the mushrooms were harvested and the growth parameters and biological efficiency was recorded. The isolated resident fungi were identified after obtaining pure cultures. The collected data were subjected to analysis (ANOVA) using Generalized Linear Model Procedure (GLM) of Statistical Analysis software (SAS). Means were separated using Duncan’s Multiple Range Test (DMRT) at p ≤ 0.05. Some of the growth parameters of P. ostreatus were significantly (p ≤ 0.05) better than that of P. pulmonarius. Tectona grandis and Celtis zenkeri sawdust had significant (p ≤ 0.05) impact on different growth parameters of the two mushrooms. Fermentation or non-fermentation of the substrates (sawdust) had no significant (p ≤ 0.05) impact on growth parameters of the mushrooms. Growth parameters of the two mushrooms were significantly better in 0% additive (p ≤ 0.05) than in the other additive concentrations. Five fungi were identified as indigenous fungi of the unfermented sawdust which did not significantly differ from those of the fermented sawdust and mushrooms. Nutritional composition of the mushrooms that grew on fermented and unfermented sawdust were good and comparable. The mushrooms were rich in protein, fibre, ash, moisture, fat and carbohydrate. Cultivation of mushrooms on hardwood sawdust is thus an effective means of managing such waste.

Summary An experiment has been conducted to study the effect of sludge concentration,  waste of paper industry using raw material of recycled paper, as media on oyster mushroom production and quality. Twelve treatment tested are combination of two oyster mushroom strains are oyster mushroom of Bogor (JTB) and oyster mushroom of Taiwan (JTT), three media composition (sawdust, sludge, and sawdust+ sludge (50/50, v/v), and two levels of supplement addition (with rice bran+gypsum+ lime and without) with 10 replications. The production of the  mushroom was conducted  in bag log capacity of 1 kg fresh weight (water content 50%). The result showed that sludge can be used as mixture of oyster mushroom production with the composition 50:50 v/v of sawdust and sludge. Since the higher number of contamination, addition of supplement reduce oyster mushroom production as well as biological efficiency, but increased protein content of fruiting body. The content of Cd, and Pb were below the permissible limits, Cu was higher than the limits but still in the range. The Fe content of mushroom fruit body was higher both in sawdust (147.92 – 149.56 ppm) and sawdust+sludge (295.82 – 335.12 ppm) as media. However, the uptake of Fe of JTT was less (49.08-59.64 ppm) compared to that of JTB (147.92-335.12 ppm).Ringkasan Penelitian dilakukan untuk mempelajari pengaruh konsentrasi sludge limbah pabrik kertas berbahan baku karton bekas sebagai medium terhadap produksi dan kualitas jamur tiram. Dua belas perlakuan yang diuji merupakan kombinasi dua galur jamur tiram, yaitu Jamur Tiram Bogor (JTB) dan Jamur Tiram Taiwan (JTT), tiga jenis komposisi medium (serbuk gergaji, sludge, dan sludge+ serbuk gergaji), dan dua tingkat suplemen (dengan dan tanpa) yang diulang 10 kali untuk masing-masing perlakuan. Produksi jamur tiram dilakukan menggunakan bag log  berkapasitas 1 kg basah (kadar air 50%). Hasil percobaan menunjukkan bahwa sludge dapat digunakan sebagai campuran serbuk gergaji dalam produksi jamur tiram dengan per-bandingan 50:50 (v/v). Pemberian suplemen menurunkan produksi jamur tiram demikian pula efisiensi biologi namun meningkatkan kadar protein tubuh buah. Di dalam tubuh buah JTB, kandungan logam Cd, dan Pb berada di bawah batas yang diijinkan, sedangkan kandungan Cu di atas ambang walaupun masih dalam kisaran. Kandungan  Fe dalam tubuh buah jamur relatif tinggi baik yang ditumbuhkan pada serbuk gergaji sebagai medium standar (147,92 - 149,56 ppm) maupun yang ditumbuhkan pada medium campuran sludge+serbuk gergaji (295,82 - 335,12 ppm). Serapan Fe tubuh buah JTT jauh lebih rendah (49,08- 59,64 ppm) dibandingkan dengan serapan Fe JTB (147,92-335,12 ppm).

Studies were conducted for 2 years in root-knot-nematode-infested soils to determine growth and yield response of `Dasher II' cucumbers (Cucumis sativus L.) to double-cropping with nematode-resistant tomatoes (Lycopersicon esculentum Mill.), using nematode-free cucumber transplants and preplant treatment with ethoprop nematicide. Cucumbers grown following the nematode-resistant `Celebrity' tomato during the same season produced significantly more plant dry weight, more fruit per plant, and higher premium and total yields than did cucumbers double-cropped with the nematode-susceptible `Heatwave' tomato in both years. The cucumber produced longer stems in 1992 and fewer culls in 1993 following resistant tomatoes. Cucumber plants raised in nematode-free soilless mix for 3 weeks before transplanting produced significantly longer stems and more plant dry weight than did direct-seeded cucumbers in 1992, but not in 1993; however, they produced significantly higher premium yield in both years, and higher total yield, more fruit per plant, and fewer culls in 1993. Preplant treatment with ethoprop significantly increased cucumber stem length, dry weight, premium and total yield, and number of fruit per plant in 1992 but not in 1993. Ethoprop treatment had no effect on the percentage of culls in either year. Chemical name used: O-ethyl S,S-dipropyl phosphorodithioate (ethoprop).

Field experiments were conducted at Punjab Agricultural University, Ludhiana (Punjab) to study the effect of different agronomic aspects of bed planting on growth and yield of rice during Kharif seasons of 2012 and 2013. The 30 days old seedlings of both rice varieties PR-118 (V1) and PR-116 (V2) were transplanted on 15th June (D1), 30th June (D2) and 15th July (D3). The two rice varieties were transplanted under bed planting (M1) and conventional planting (M2) methods respectively. The results showed that growth parameters like number of tillers per plant, dry weight per plant leaf area index (LAI) and plant height were significantly higher in bed planting than conventional method. In bed planting method, grain yield of rice (48.82q/h) was found to be more than the conventional method (35.74 q/h) during 2012.Varieties PR-118 yielded 47.61q/h more than PR-116 (39.97 q/h) in bed planting. Yield contributing characters like number of effective tillers, number of grains per plant and 1000-grain weight of rice were more in bed planting than conventional method. Harvest index and biological yield was also found to be more in bed planting method than conventional planting. Rice transplanted on 15th June yielded (50.15q/h) more than 30th June (41.45q/h) and 15th July (35.27q/h). Similar results were found in Kharif 2013. Interaction between dates of transplanting and varieties and between varieties and planting methods were found significant.
