Aim: To investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium. Study Design: The experiment was laid out in Randomized Block Design with three replications. Place and Duration of Study: Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry. Methodology : The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2). Results: The results of a field experiment revealed that the two splits of potassium increased the available P at the active tillering stage and harvest stage. Whereas, three splits increased the available P at panicle imitation and flowering stage. The KCl recorded higher available P at panicle initiation and harvest stages. The high phosphorus uptake was recorded in panicle initiation and flowering stages by three splits application of potassium. In grain also, especially the three splits through KClO3 recorded higher P uptake. Conclusion: The split applications tested in this investigation influenced the available phosphorus status in soil and phosphorus uptake. Increase in splits of potassium increased the P uptake. This result is in agreement with the results of Mitra et al. [1] who observed a significant increase in the uptake of N, P, K and S by increased level of K in Kharif rice.

Yield is a net expression of genotype (G) x environment (E) interactions including management. However, the segregation of 'E' into respective causes is seldom done while 'G' is a constant. Soil is a component of 'E' with imminent variability in attributes among multiple locations. Data on yield response of varieties to a set of treatments in different soils from multi-locational yield maximisation trial under All India Coordinated Rice Improvement Project were regularly gathered. A dataset pertaining to a trial conducted in Karaikal district of Puducherry Union Territory was analysed to ascertain the site-specific crop responses with inherent variability in soils. Rice varieties, ADT 46, BPT 5204 and CR 1009 were tested for responses at 17 sites with farmer fertiliser practices (FFP), regional recommended fertiliser dose (RDF) and software, 'Nutrient Expert®' (2016) (NE) derived fertiliser quantities. Analysis of variance showed that test sites explained 59.3% variability in yield. A multivariate technique, Factor Analysis extracted two factors, which are linear combinations of soil attributes those explained 76% of variance in soils. Factor scores classified soils into four groups, owing to variability in soil properties. Soil texture influenced yield significantly (across varieties and treatments) (R2 = 11.1%). Sites varied in excess duration in nursery ranging from 2 - 26 days. However, this excess duration reduced number of panicles m-2 only in CR 1009 (r = -0.328**). General linear model with sites and treatments as fixed factors, their interactions and panicles m-2 as covariate predicted better (R2 = 90.3%) with their significant contribution to the model. The order of R2 (%) was Sites (59.3) > Varieties (27.4) > Treatments (13.6%) in explaining variability in yield highlighting site-specific responses. Mean differences between ADT 46 and BPT 5204; BPT 5204 and CR 1009 were significant. Yield significantly changed across sites and treatments when fertiliser management shifted from non-specific (FFP) to site-specific NE based calculations through RDF (region specific). Results of this trial placed emphasis on soil test-based crop management to realise the uniform best, which clearly is site specific crop management.

Masalah kesehatan dijumpai di kalangan anak prasekolah/TK adalah berkurangnya nafsu makan anak makin meningkat. Makanan yang disuguhkan ibu harus mengandung unsur nutrisi serta sejumlah vitamin, mineral, dan serat seperti buah tomat. Tujuan penelitian ini untuk menganalisis pengaruh jus buah tomat terhadap peningkatan nafsu makan pada tikus putih (Ratus Novergicus Stain Wistar).  Desain penelitian adalah true eksperimental dengan pendekatan metode pretest-posttest with control group. Populasinya tikus putih (ratus novergicus stain wistar), dengan sampel 20 tikus, tekhnik purposive sampling. Pengumpulan data dengan observasi.  Hasil penelitian pada kelompok kontrol peningkatan berat badan rata-rata 0,12 gr – 0,37 gr dan porsi makan rata-rata 0,04 gr – 0,86 gr. Sedangkan pada kelompok perlakuan peningkatan berat badan rata-rata 0,63 gr – 5,33 gr dan peningkatan porsi makan rata-rata 0,04 gr– 3,14 gr. Analisis Uji  Uji T sampel beerpasangan didapatkan hasil nilai sig (2-tailed) nilai p: 0,000 dan a: 0,05, jadi p value <a sehingga H0 ditolak dan H1 diterima, artinya ada pengaruh buah tomat (solanum lycopersicum) terhadap nafsu makan tikus putih (ratus novergicus stain wistar), dengan kekuatan pengaruh 95% dan arah pengaruh positif. Masyarakat yang mempunyai anak usia pra sekolah untuk memberikan buah tomat setiap hari dengan tujuan meningkatkan nafsu makan anak sehingga tumbuh kembang anak dapat berkembang dengan baik.
