A field experiment was conducted at Bidi Tobacco Research Station, Anand Agricultural University, Anand for four years from 2014-15 to 2017-18 with the objective to study the effect of organic and inorganic sources of fertilizers on growth, yield and quality of bidi tobacco variety GABT 11. Results revealed that different manures and fertilizers failed to exert their significant effect on yield of bidi tobacco variety GABT 11 during all four years and in its pooled. Green manuring every year with sunnhemp recorded significantly maximum leaf size viz. leaf length and width followed by application of FYM @ 12.5 t/ha every year. Besides, Application of 180 kg N/ha through ammonium sulphate gave significantly higher tobacco plant height over application of 180 kg N/ha through castor cake and application of 135 kg N/ha through ammonium sulphate + 90 kg P2O5/ha through single super phosphate + 135 kg K2O/ha through sulphate of potash. Maximum monetary returns with benefit: cost ratio of 2.68 accrued with treatment of 180 kg N/ha through Ammonium sulphate. Among different bulky manures, green manuring with sunnhemp every year gave maximum gross income and net income with BCR value 2.43.

Field experiments were conducted to determine the effect of two chlorinated hydrocarbon nematicides on control of the root lesion nematode Pratylenchus penetrans (Cobb) and on the yield and quality of flue-cured tobacco. The nematode was effectively controlled with a spring or fall application of either D-D or Telone. Fall application resulted in an increase in total nitrogen and total alkaloids and a decrease in reducing sugars and ethanol extractables in the cured tobacco leaf, effects which are associated with low quality. Evidence indicated that fall fumigation inhibited the nitrification of ammonium nitrogen fertilizer applied to the rye straw in the summer preceding the tobacco crop. Excessive amounts of mineral nitrogen became available to the tobacco plant during its growing season. Spring application increased the chlorine content of the leaf but had no other adverse effects on chemical composition.

A study was conducted with graded levels of potassium and sulphur on pigeon pea to assess the nutrient uptake, yield and quality at Agronomy Farm, College of Agriculture, Nagpur (M.S.) The data revealed that application of K and S levels significantly influenced the uptake of major and micronutrient in pigeon pea. High N and P uptake was observed due to application of 30 kg potassium and 20 kg sulphur per hectare. Potassium uptake was increased significantly with increasing the levels of K. The highest K uptake was noticed in 45 kg K and 20 kg S per hectare combination. The recovery of NPK was higher in 30 kg potassium per hectare. Due to increased level of potassium and sulpur there was no adverse effect on calcium assimilation and highest uptake of calcium was observed in the application 30 kg K and 20 kg S per hectare. The optimum supply of K and S improves the uptake of micronutrients. Significantly high grain yield and protein yield was observed due to application 30 kg K and 20 kg S per hectare. Therefore balanced fertilization of NPKS nutrients is required in pigeon pea.

<p>Hasil dan mutu tembakau temanggung merupakan hasil interaksi antara pengaruh genetik tanaman dan kondisi lingkungan tumbuh. Pada tembakau virginia, fenologi tanaman merupakan salah satu karakter gene-tik tanaman yang mempengaruhi hasil dan mutu, sedangkan pada tembakau temanggung belum banyak di-ketahui. Penelitian yang bertujuan untuk memperoleh informasi fenologi tanaman yang menjadi karakter ge-netik tanaman dan kaitannya dengan hasil dan mutu rajangan kering dilakukan di rumah kaca Balai Peneliti-an Tanaman Tembakau dan Serat (Balittas), Malang sejak Maret–Agustus 2008. Sembilan kultivar tembakau temanggung disusun dalam rancangan acak kelompok yang diulang tiga kali. Pengamatan dilakukan pada peubah saat muncul daun, daun berhenti meluas, daun dipanen, muncul bunga, pemangkasan, panen awal, dan panen akhir. Analisis stepwise digunakan untuk mengidentifikasi fenologi tanaman yang mempengaruhi hasil dan mutu. Hasil penelitian menunjukkan bahwa fenologi tanaman yang mencakup lama waktu dari mun-cul daun sampai daun berhenti meluas, muncul daun sampai panen, daun berhenti meluas sampai panen, tanam sampai muncul bunga, tanam sampai pemangkasan, tanam sampai panen akhir, muncul bunga sam-pai panen akhir, pemangkasan sampai panen akhir, dan panen awal sampai panen akhir merupakan karak-ter genetik tanaman tembakau temanggung. Karakter fenologi utama yang mempengaruhi hasil rajangan ke-ring berurutan dari yang terbesar adalah lama waktu dari tanam sampai pemangkasan, muncul daun sampai daun berhenti meluas, tanam sampai panen akhir, panen awal sampai panen akhir, dan muncul bunga sam-pai panen akhir dengan total pengaruh sebesar 90,3%. Adapun karakter fenologi utama yang mempenga-ruhi mutu rajangan kering berurutan dari yang terbesar adalah lama waktu dari tanam sampai pemangkas-an, daun berhenti meluas sampai panen, muncul daun sampai daun berhenti meluas, tanam sampai panen akhir, dan panen awal sampai panen akhir dengan total pengaruh sebesar 84,7%.</p><p> </p><p>Yield and quality of temanggung tobacco are influenced by plant genetic and growth environmental factors. Plant phenology is one of genetic characters which affects on yield and quality of virginia tobacco. Plant phe-nology of temanggung tobacco is not yet well defined. The research, aimed to find plant phenology as gene-tic characters related to dry sliced yield and quality of temanggung tobacco, was conducted in glass house of Indonesian Tobacco Research and Fibre Crops Institute (IToFCRI) from March to August 2008. Nine cultivars of temanggung tobacco were arranged in randomized block design with three replications. Variables ob-served were leaf initiation, terminal leaf expansion, harvesting period, flowers initiation, and final harvesting. Stepwise analysis used to identify plant phenology which affect on yield and quality. The results showed that the phenology of plants that includes the length of time from leaf initiation to terminal leaf expansion, leaf initiation to harvesting period, terminal leaf expansion to harvesting period, planting to flowers initiation, planting to pruning, planting to final harvesting, flowers initiation to final harvesting, pruning to final har-vesting, and first harvesting to final harvesting were genetic characters of temanggung tobacco. The main phenological characters that affect on dry sliced yield sorted from the largest is the length of time from planting to pruning, leaf initiation to terminal leaf expansion, planting to final harvesting, first harvesting to final harvesting, and flowers initiation to final harvesting with total effect of them was 90.3%. The main phe-nological characters that affect on quality of dry slice sorted from the largest is the length of time from planting to pruning, terminal leaf expansion to harvesting period, leaf initiation to terminal leaf expansion, planting to final harvesting, and first harvesting to final harvesting with total effect of them was 84.7%.</p>

SUMMARYField experiments were conducted during 1983–85 and 1984–86 on an entisol at Lucknow, India. Dry herbage, essential-oil yields and nutrient uptake increased significantly with the application of 83 kg K/ha. Considering the means from both experiments over a two-year cropping cycle, the application of 41·5 kg K/ha in four splits exceeded the zero K control by 6·8 t/ha (dry matter) and 233 kg/ha (oil), and exceeded a basal application of 83 kg/ha K by 2·8 t/ha (dry matter) and 109 kg/ha (oil). Amounts and methods of K application showed no effect on oil quality. Application of 41·5 kg K/ha in four splits, one after each harvest, is recommended to obtain maximum yields in this perennial grass.
