The vegetable crops viz., TNAU tomato hybrid CO 3 and coriander variety CO 4 were raised under different cultivation systems viz., 50 per cent shade net, insect proof net house and open field conditions. Growth and yield characters of tomato and coriander were assessed during s ummer 2013 and 2014 under different systems of cultivation. The number of fruits per plant (54.3) and weight of fruits per plant (2.1 kg) with estimated yield (67.17 t / ha) of TNAU tomato hybrid CO 3 was highest under insect proof net house followed by shade net house and the lowest was noticed under open field cultivation. The highest single plant weight (52.1 g) with estimated herbage yield (3.33 t / ha) of coriander were recorded under insect proof net house followed by shade net and the lowest under open field cultivation. Among the two crops, the highest BCR (2.58) was observed with tomato hybrid CO 3 under insect proof net house followed by shade net house (2.45). The lowest BCR of 1.31 was recorded with the cultivation of coriander variety CO 4 under open field condition. Therefore, it can be concluded that tomato could be highly remunerative crop suitable for cultivation under insect proof net house condition during summer season.

Evaluation of sweet pepper cultivation under different protective structures was made in two consecutive seasons of 2007-08 and 2008-09 at the experimental field of Horticulture Research Center of BARI, Gazipur. One popular commercial capsicum variety California Wonder was included in the study with four protective structures (low height poly tunnel, polytunnel with side open, poly tunnel with side closed and poly house) including control (open field). Protective structures had remarkable and significant influence on plant growth and yield of sweet pepper. The plants grown under protective structures had higher plant height compared to that of plants grown in open field. The highest individual fruit weight (65.2g) was recorded form the plants grown under poly house condition while it was the lowest from open field grown plant (3.34 g). More than five fruits were harvested when the plants were grown under poly tunnel (side closed) or poly house. The maximum fruit yield per plant (334.0g) was recorded from poly house, which was 160.4% higher than that of plants grown under open field condition. The second highest yield was recorded from the plants of poly tunnel (212.5) indicating bright scope for sweet pepper cultivation under protective structures.

<p>Bawang merah termasuk sayuran bumbu yang dibutuhkan oleh masyarakat dan harganya bersifat fluktuatif sehingga diperlukan kecukupan produksi untuk mendukung kestabilan harga. Kecukupan produksi dapat tercapai melalui pemanfaatan lahan marjinal seperti Ultisol yang masih luas dan perbaikan teknik budidaya, di antaranya melalui aplikasi pupuk Mikotricho. Tujuan penelitian adalah mengkaji pupuk Mikotricho dengan pengurangan dosis N-P-K terhadap pertumbuhan dan hasil bawang merah. Penelitian berupa percobaan lapang di lahan Ultisol menggunakan Rancangan Acak Kelompok Lengkap faktorial dengan tiga ulangan. Faktor pertama, dosis pupuk Mikotricho, yaitu 10 g, 30 g, dan 50 g/tanaman, faktor kedua, pengurangan dosis N-P-K berupa Urea, SP-36, KCl, dan ZA, yaitu 0, 25%, dan 50% dari rekomendasi. Hasil penelitian menunjukkan, aplikasi pupuk Mikotricho meningkatkan jumlah daun (11,4%) dan bobot tanaman segar (49,1%) bawang merah secara linier positif dengan dosis terbaik 50 g/tanaman. Hasil umbi/rumpun dan per petak efektif (0,64 m2) dosis pupuk Mikotricho, 10 g, 30 g, dan 50 g/tanaman tidak berbeda. Pengurangan dosis N-P-K dari rekomendasi berpengaruh terhadap jumlah anakan dan bobot segar tanaman bawang merah dengan efek linier negatif, namun pengurangan 25% dosis N-P-K dapat dipilih. Pengaruh interaksi pupuk Mikotricho dengan pengurangan dosis N-P-K terjadi pada kehijauan daun dan luas daun. Pemberian pupuk Mikotricho dosis 10 g hingga 30 g/tanaman dengan pengurangan dosis N-P-K 25% hingga 50% dari rekomendasi meningkatkan kehijauan daun dan luas daun bawang merah. Implikasi dari penelitian ini adalah diperlukan sosialisasi pemanfaatan pupuk Mikotricho pada budidaya tanaman bawang merah atau tanaman sayuran lain untuk mengurangi pemakaian pupuk sintetik dan perlu dukungan industri pembuatan pupuk Mikotricho.</p><p><strong>Keywords</strong></p><p>Mikoriza; <em>Trichoderma</em>; N-P-K; Bawang merah; Lahan marginal</p><p><strong>Abstract</strong></p><p>Shallots are a spice vegetable needed by the community. Adequacy of production can be achieved through the use of Ultisols with application of Mikotricho fertilizer. The aim of this research was to study the Mikotricho fertilizer with a reduced dose of N-P-K on growth and yield of shallots. The research was a factorial RCBD with three replications. The first factor, namely 10 g, 30 g, and 50 g/plant Mikotricho fertilizer dose, the second factor, namely 0, 25%, 50% N-P-K reduction of the recommendation.The results showed that Mikotricho fertilizer increased the number of leaves (11.4%) and fresh plant weight (49.1%) of shallots, the best dose of 50 g/plant. The yield bulbs/clump and per plot (0.64 m2) 10 g, 30 g, and 50 g Mikotricho fertilizer were not different. The 25% reduction in the N-P-K can be chosen to the number of tillers and fresh weight of shallots plants. Apply of Mikotricho fertilizer 10 g until 30 g/plant with a reduction in the N-P-K of 25% until 50% increases leaf greenish and leaf area. The implication was that socialization of Mikotricho fertilizer in cultivation of shallots or other vegetable crops to reduce the use of synthetic fertilizers and needs the support of the Mikotricho fertilizer manufacturing industry.</p>

Tomato is a high-value vegetable crop because of its broad culinary uses and nutritional values. Its production however is inhibited in some areas with soil-borne disease problems, particularly bacterial wilt. This study was conducted to evaluate the yield, bacterial wilt infection, and profitability of non-grafted and grafted tomato cultivars planted in open field and protected cultivation. Protected cropping of tomato increased number of marketable fruits and total yield by approximately 2 times fold than those grown in open field. Grafting of the cultivars to eggplant significantly reduced bacterial wilt infection such that increased survival among plants resulted to higher yield than non-grafted. The cultivar with biggest fruits was from ‘Kingkong’ while season red had the smallest and other cultivars were in average size of the two. Grafted ‘Diamante max’ cultivar yielded the highest followed by ‘Season red’. Net return of protected cropping tomato was higher than in open field. Non-grafted tomato grown in bacterial wilt infected area was unprofitable. On the other hand, grafting and protected resulted in better yield, gross income and a positive net return. Season red produced the highest income in the open field while Diamante max for protected cultivation. The use of grafted tomato and protective structure are strongly recommended for planting in areas known to have high bacterial wilt.

An investigation was carried out at the Department of Horticulture, University of Agricultural Sciences, Bangalore during summer-2017 to study the effect ofvaried levels of nitrogen and phosphorus fertigation on cherry tomato under open field and polyhouse conditions. There were 12 treatment combinations comprising of two growing conditions (open field and polyhouse), three levels of nitrogen (120, 150 and 180 kg N ha-1) and two levels of phosphorus (100 and 120 kg P2O5 ha-1) supplied trough fertigation with recommended potassium (150 kg h-1) as constant which were laid out in Factorial Randomized Complete Block Design with three replications. Result revealed that plant height (384.39 cm), fresh weight per plant (3.00 kg),nitrogen balance index (48.56), total leaf area per plant (6293 cm2), mean fruit weight (15.84 g), TSS content (6.30 ºB) and shelf life (15.66 days) were significantly higher under polyhouse condition with fertigation level of 180:120 kg N:P2O5 ha-1. However, significantly higher yield per hectare (78.16 t), Shelf life (15.66 days) and higher cost benefit ratio (4.81) were observed under open field condition with fertigation level of 150:120 kg N: P2O5 ha-1. Further, it can be concluded from the study that application of 150:120 kg N: P2O5 ha-1 through fertigation under open field condition is profitable during summer season in the Eastern Dry Zone of Karnataka.

This study aimed to identification of an ecological alternative for the chemical disinfection of soil in the greenhouses from Romania. Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops in the world. The carbohydrate, vitamins, salts of important mineral elements and organic acids content of tomato fruits is very important. Tomato crops are very sensitive to climatic vagaries, so fluctuation in climatic parameters at any phase of growth can affect the yield and the fruit quality. Grafting on Solanaceae is a method which has improved and spread quickly during the past years, a similar approach to crop rotation, a practice meant to increase productivity, resistance or tolerance to biotic and abiotic stress factors and at increasing fruit quality. The research was conducted in a glass greenhouse of the Horting Institute, Bucharest, Romania. The biological material used was a Romanian tomato hybrid (Siriana F1), a Dutch tomato hybrid (Abellus F1) and four rootstocks, a Dutch tomato hybrid (Emperador F1) and three Romanian tomato cultivars (L542, L543 and L544) obtained from the Research and Development Station for Vegetable Growing, Buzău, Romania. The rootstocks have had resistance to biotic stress factors (soil diseases and pests) and the chemical disinfection of soil has was eliminated. The result of this research are presented in this paper.

The use of biofertilizers is important for sustainable agriculture, and the use of nodule bacteria and endophytic actinomycetes is an attractive way to enhance plant growth and yield. This study tested the effects of a biofertilizer produced from Bradyrhizobium strains and Streptomyces griseoflavus on leguminous, cereal, and vegetable crops. Nitrogen fixation was measured using the acetylene reduction assay. Under N-limited or N-supplemented conditions, the biofertilizer significantly promoted the shoot and root growth of mung bean, cowpea, and soybean compared with the control. Therefore, the biofertilizer used in this study was effective in mung bean, cowpea, and soybean regardless of N application. In this study, significant increments in plant growth, nodulation, nitrogen fixation, nitrogen, phosphorus, and potassium (NPK) uptake, and seed yield were found in mung beans and soybeans. Therefore, Bradyrhizobium japonicum SAY3-7 plus Bradyrhizobium elkanii BLY3-8 and Streptomyces griseoflavus are effective bacteria that can be used together as biofertilizer for the production of economically important leguminous crops, especially soybean and mung bean. The biofertilizer produced from Bradyrhizobium and S. griseoflavus P4 will be useful for both soybean and mung bean production.
