Greater attention should be paid for increasing the yield per unit area by growing modern varieties of rice through improved cultivation practices. An experiment was conducted for investigating the effect of variety and date of harvesting on yield performance of modern rice varieties during Kharif, 2012 at Agricultural Research Station, Bapatla. The experiment was laid out in a split-plot design with three replications. Main treatments comprised of four rice varieties namely, BPT 5204, BPT 2270, BPT 2231, NLR 34449, NLR 28523 and MTU 1010 and sub treatments comprised of three time of harvesting viz., 25, 30 and 35 days after flowering. Plant growth, yield attributes, yield and quality of rice varieties were significantly influenced by different dates of harvesting. BPT 2270 was found significantly superior to all other varieties in respect of effective tillers, grains panicle-1, grain yield, straw yield and hulling per cent, milling per cent and head rice recovery. Among three harvesting times, the highest grain yield (6250 kg ha-1) and straw yield (7314 kg ha-1) were obtained when the crop was harvested at 30 days after flowering. The interaction effect of variety and date of harvesting was significant in respect of grain and straw yield. The highest grain yield (7771 kg ha-1) was observed in BPT 2270 when harvested at 30 days after flowering. Therefore, optimum date of harvesting for higher grain yield may be 30 days after flowering for avoiding immature stage as well as shattering loss.

A field experiment was conducted to investigate the effectiveness of different herbicides for controlling wild onion (Asphodelus tenuifolius) in cumin (Cuminum cyminum L.) during the rabi seasons (2018–2019 and 2019–2020) at Agricultural Research Station, Agriculture University, Jodhpur, Rajasthan. The experiment comprised eight herbicidal weed management treatments for wild onion applied to cumin in a three-replication randomized block design. Among the herbicidal weed management treatments, early post-emergence (8 DAS) application of oxyfluorfen 200 g/ha resulted in the lowest weed density and dry matter of Asphodilus tenuifolius, with maximum weed (Asphodilus tenuifolius) control efficiency at 40 days after sowing (DAS) during both experimental years. Likewise, the highest total efficiency of weed control was recorded with the application of oxyfluorfen 200 g/ha at 8 DAS. Oxyflourfen 200 g/ha used early post emergence (8 DAS) reduced the weed index more effectively than the other herbicides. It also recorded the highest number of branches/plant, plant height, umbels/plant, umbellates/umbel, seeds/umbellates, and seed yield. However, application of oxyflourfen @ 200 g/ha 8 DAS–early POE and pendimethalin 38.7 CS 500 g/ha + oxyfluorfen @ 150 g/ha 8 DAS–early POE were statistically similar in terms of plant growth, yield, and yield attributes. The net returns (366.49 USD/ha in 2018–2019 and 175.72 USD/ha in 2019–2020) and B:C ratio (1.70 and 1.33 in 2018–2019 and 2019–2020, respectively) were also superior, with oxyfluorfen 200 g/ha applied early post emergence.

Penelitian dengan tujuan untuk<br />mengetahui respon lima aksesi jahe putih kecil terhadap pemupukan dosis<br />rendah telah dilaksanakan di Kebun Percobaan Cimanggu pada bulan<br />Agustus 2009 sampai Mei 2010. Lima aksesi jahe putih kecil dari daerah<br />marginal ditanam dalam polibag dan disusun menggunakan rancangan<br />acak kelompok yang diulang 3 kali. Setiap perlakuan terdiri atas 20<br />tanaman. Dua perlakuan yang diuji secara faktorial adalah, faktor I adalah<br />5 aksesi jahe putih kecil, yaitu (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008,<br />(4) Ziof 0013, dan (5) Ziof 0014, dan faktor II adalah dosis pupuk, yaitu<br />(a) 50% dosis anjuran (200 kg/ha urea + 150 kg/ha SP-36 + 150 kg/ha<br />KCl), (b) 75% dosis anjuran (300 kg/ha urea + 225 kg/ha SP-36 + 225<br />kg/ha KCl), dan (c) dosis anjuran (400 kg/ha urea + 300 kg/ha SP-36 +<br />300 kg/ha KCl). Masing-masing perlakuan diberi pupuk kandang sebagai<br />pupuk dasar dengan dosis 20 t/ha. Pengamatan dilakukan terhadap<br />parameter pertumbuhan (tinggi tanaman, jumlah anakan, diameter batang,<br />dan jumlah daun), hasil dan serapan unsur hara N, P, dan K pada umur 4<br />BST dan 9 BST. Hasil penelitian menunjukkan bahwa masing-masing<br />aksesi memberikan respon yang berbeda terhadap penurunan dosis pupuk,<br />baik pada fase pertumbuhan maupun produksi tanaman jahe. Pengurangan<br />dosis pupuk sampai 25% tidak mengurangi produksi jahe, tetapi penurunan<br />dosis pupuk sampai 50% dari dosis rekomendasi menyebabkan penurunan<br />produksi jahe secara nyata.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Sustainable Sugarcane Initiative (SSI) under Sub Surface Drip Irrigation (SSDI) is gaining momentum among the farmers because of more output with less input. Even though the benefits of SSI under SSDI are realized by farmers, development of optimal irrigation and fertigation schedule is need of the hour for Western Agro-climatic zone of Tamil Nadu. Field trials were carried out at Agricultural Research Station, Bhavanisagar from 2014 to 2017 to develop an optimal irrigation and fertigation schedule for SSI for Western Agro-climatic zone. The experiment was taken in a randomized block design with three replications. The experiment consisted of eight treatments of which six treatments comprised of SSDI with three irrigation regimes of 100, 80 and 60 percent pan evaporation and two fertigation levels of 100 and 75 percent of recommended N & K and two treatments in surface drip irrigation (SDI) with 100 percent pan evaporation (PE) + 100 percent RD and 100 percent PE + 75 percent RD of N&K through fertigation. The results of this study revealed that SSDI with 60 per cent PE + 100 per cent RD of N&K through fertigation recorded lower water use (1004 mm) and higher WUE (113 kg/ha-mm). However, significantly higher and comparable yield of sugarcane (148 t/ha) was recorded in SSDI with 100 per cent PE + 100 per cent RD of N&K through fertigation and surface drip irrigation with 100 per cent PE + 100 per cent RD of N&K through fertigation. The net return (Rs. 2,09,405 per ha) and B:C ratio (2.6) was higher in SSDI with 100per cent PE + 100 per cent RD of N&K through fertigation treatment.
