A field experiment was conducted during the summer season of 2013 at Central Potato Research Station, Shillong, Meghalayato study the effect of sea weed saps on growth and productivity of potato in the North Eastern hill region of India.The trial was laid out in randomized block design, replicated thrice, with 10 treatments. The number of shoot per plant was found to be non-significant and vary from 2.8 to 3.0. The maximum plant at harvest was recorded under application 7.5 Kappaphycus Spray + 100% RDF while lowest under 6.25% + 50% RDF.Maximum small size tuber was found with an application of 10 % Gracilaria spray + RDF which was at par with 2.5 % Kappaphycus spray + RDF and 7.5 % Gracilariaspray + RDF but significantly superior to other treatment. However, the highest medium size tube of potato was noticed under 6.25% Kappaphycus spray along with 50% recommended dose of fertilizer. Highest large size tuber was recorded with an application of 5% Kappaphycusspray + RDF followed by 2.5% Kappaphycus spray along with RDF as well as 7.5 % Gracilaria spray + RDF which was at par, but significantly superior to rest of treatment. Application of 2.5% Kappaphycus spray + 100% RDF recorded the highest productivity of potato (27.1 t/ha) followedby 100% RDF + Kappaphycus spray @ 5.0% (26.6 t/ha) which were at par with each other but significantly superior to the rest of treatments.Based on the economic yield of potato, it may be concluded that the application of 2.5 % Kappaphycus spray + 100% RDF was found to be more profitable under rainfed condition of Meghalaya

The trial was laid out in two factors Factorial Randomized Complete Block Design. There were nine treatments with three replications. The treatments comprised of three dates of planting (30th October, 14th and 29th November) and three potato clones (Janakdev, Lbr 40 and PRP 266264.1). The results showed that the main effects of planting dates and potato clones significantly (P<0.05) affected most growth, yield and yield attributing parameters of the crop. Interaction effect of planting dates and potato clones also significantly influenced the number of above-ground stems per plant, ground cover percentage, number of tubers per plant, number and weight of small size tuber (<25 g), weight of medium or seed size (25-50 g) tuber and large size (>50 g) tuber, number and yield of tubers per plot, and yield t/ha. The highest yield (37.05 t/ha) was obtained from 14th November planting. The clone Lbr 40 produced a higher yield (36.05t/ha). The clone PRP 266264.1 planting on 30th October planting produced significantly a higher yield (41.34t/ha). The clone Lbr 40 produced significantly highest number and weight of large size (>50 g) tuber. Number of small size (<25 g) tuber per plot or unmarketable tuber significantly increased on delayed planting.

ABSTRACT Nitrogen is essential for sustaining life on the planet, and it is the most important nutrient for obtaining high agricultural production. However, their use leads to the release of nitrous oxide with a global warming potential 296 times higher than the CO2 molecule, making it a challenge to reduce their use in agriculture. The objective of this research was to identify efficient popcorn inbred lines and responsive nitrogen use and exhibit a good expansion volume. For this, 29 inbred lines from the Germplasm Collection of Darcy Ribeiro North Fluminense State University (UENF) were evaluated at two contrasting levels of nitrogen availability (low and ideal) at two representative locations in the north and northwest of the state of Rio de Janeiro, Brazil, arranged in a randomized block design with three replicates. These inbred lines were discriminated against efficient use of nitrogen by multivariate GGE Biplot. Selective accuracy was close to 1, showing that the genotypes were enough to provide contrasting success in selection procedures. The first two main components (PC) retained 93.82% of the total variation, and PC1 furnished an information ratio (IR) that was unaffected by noise. L77 was the most unstable line, while P7, P2, P6, P3, P5, P4, P9, P10, P8, P9, L70, L74, and L55 were efficient and responsive. The GGE biplot method is recommended for the reliable identification of popcorn lines that are efficient and responsive to the use of nitrogen.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

A field experiment was conducted during 2016-17 at AICRP on Integrated Farming Systems, Regional Sugarcane and Rice Research Station, Rudrur to diversify existing rice-rice cropping system with less water requiring crops under irrigated dry conditions for vertisols of Northern Telangana Zone. The experiment was laid out with twelve cropping systems as treatments in Randomized Block Design (RBD) with three replications. The twelve combinations of cropping systems tested during kharif and rabi seasons were rice – rice (check), maize + soybean (2:4) – tomato, maize + soybean (2:4) - rice, maize - sunflower + chickpea (2:4), maize - chickpea, Bt cotton + soybean (1:2) on broadbed – sesame + groundnut (2:4), Bt cotton - sesame + blackgram (2:4), soybean – wheat, soybean – sunflower + chickpea (2:4), turmeric – sesame, turmeric + soybean (1:2) on flat bed – bajra and turmeric + soybean (1:2) on broadbed – sesame + blackgram (2:4). On system basis, significantly higher productivity in terms of rice equivalent yield (REY) of 23830 kg ha-1 was recorded with turmeric+soybean (1:2) BBF– sesame+blackgram (2:4) turmeric – sesame cropping sequence. However it was on par with turmeric – sesame and turmeric + soybean (1:2) on flat bed – bajra crop sequence with productivity of 23332 kg ha-1 and 21389 kg ha-1 respectively. Lower productivity was recorded with rice-rice cropping system (10725 kg ha-1). Significantly higher system net returns were recorded with Bt. cotton – sesame + black gram (2:4) on BBF (Rs222838 ha-1) closely followed by Bt Cotton + Soybean (1:2) (BBF) - Sesamum + Groundnut (2:4) (Rs221160 ha-1) and Maize+soybean (2:4)–tomato (Rs212909 ha-1). Lower system net returns were recorded in conventional rice-rice system (Rs88179 ha-1). Bt. cotton – sesame + black gram (2:4) and Bt Cotton + Soybean (1:2) (BBF)- Sesamum + Groundnut ((2:4) and Maize+soybean (2:4)–tomato were economically superior with REE of 152.71%, 150.81% and 141.45%. Rice- Rice cropping adopted by majority of farmers is less productive and economically inferior indicating wider scope of diversifying existing rice- rice cropping system with high productive, economically viable cropping systems in vertisols of Northern Telangana Zone.
