Shallots are one of vegetable that can be cultivated with bulb or seeds. Shallot seeds better known as True Shallot Seed (TSS). Shallot cultivation using TSS still encounters several obstacles including low physiological quality of seeds. Physiological quality of seeds can be improved by plant growth regulators (PGR) application both natural or artificial. One of popular natural PGR is coconut water. The goal of this experiment was to determinate the effectiveness of various types of coconut water at freshness various levels toimprove TSS physiological quality. This experiment use factorial completely randomized design with 3 replications. First factor is 3 types of coconut water that are Gading Coconut, Hijau Coconut and Dalam Coconut. Second factor is 4 levels of water coconut freshness that are fresh coconut water, coconut water stored for 1 day, coconut water strored for 2 days and coconut water stored for 3 days. TSS used in this experient was Tisula variety. The result showed that various types of coconut water could improve physiological quality of TSS. Maksimum results obtained in HijauCoconut water with fresh, stored 1 day and strored 2 days treatment. Also Dalam Coconut water in fresh and stored 1 day. Gading Coconut water is also able to improve TSS physiological quality although the result as not as good Hijau Coconut and Dalam Coconut.
The objective of research was to determine the growth and yield of three sorghum varieties in Kediri. This research was implemented on June-September 2019 at Agriculture Integrated Field Laboratory, UNISKA, Kediri with altitude 46 meters above sea level, <5% slope, alluvial soil with sandy clay structure. This research used Randomized Block Design, single factor of three sorghum varieties (Kawali, Numbu and Suri 4). Result represented that growth and yield had a significant effect. All varieties grow well under drought condition in Kediri, but only Numbu and Suri 4 are able to provide maximum yield.
Chili is an important horticultural commodity in Indonesia. However, its production is still not optimal because there are not many superior seeds available, which causes low productivity. One solution to this problem is to improve planting material (seeds) by a plant breeding program through a hybridization process. Crossing different types of chili requires the right time to increase the chances of success. The purpose of this study was to determine the effectiveness of crossing three genotypes of chili (two introduced and one local). The study was carried out with a factorial randomized design. The first factor was a combination of crosses of three parents, namely Sweet Italian, Garda and Katokkon by dialel crosses. The second factor was the time of crossing, namely at 04.00, 05.00, 06.00, 07.00, 08.00. The results of the analysis showed that the combination of parents had an interaction with crossing time in increasing the dsuccess of the crosses. Each parent combination hah a specific time for crossing. If the female parent was Sweet Italian, the time of crossing early in the morning (low temperature) was more optimal, which was between 04.00-07.00. For Katokkon×Garda crosses and their reciprocals, the percentage of successful crosses increased if it was done at 06.00-08.00. None of the crosses between Garda×Sweet Italian were successful or were entirely lethal.

Namun produksinya masih belum optimal karena belum banyak tersedia benih unggul, yang menyebabkan rendahnya produktivitas. Salah satu solusi masalah tersebut adalah dengan perbaikan bahan tanam (benih) melalui program pemuliaan tanaman dengan proses persilangan (hibridisasi). Persilangan cabai yang berbeda jenis memerlukan waktu yang tepat untuk dapat meningkatkan peluang keberhasilannya. Tujuan penelitian ini adalah untuk mengetahui efektivitas waktu persilangan tiga genotipe cabai (dua introduksi dan satu lokal). Penelitian dilaksanakan dengan rancangan acak kelompok faktorial, Faktor pertama adalah kombinasi persilangan dari tiga tetua, yaitu Sweet Italian, Garda dan Katokkon secara dialel. Faktor kedua adalah waktu persilangan, yaitu pada pukul 04.00, 05.00, 06.00, 07.00, 08.00. Hasil analisis menunjukkan bahwa kombinasi tetua memiliki interaksi dengan waktu persilangan dalam meningkatkan keberhasilan persilangan. Tiap kombinasi tetua memiliki waktu yang spesifik untuk persilangan. Jika tetua betina Sweet Italian, waktu persilangannya semakin pagi (suhu rendah) semakin optimal, yakni di antara pukul 04.00-07.00. Untuk persilangan Katokkon×Garda maupun resiproknya, persentase keberhasilan persilangan semakin meningkat jika dilakukan pada pukul 06.00-08.00. Tidak ada penyerbukan silang antara Garda×Sweet Italian yang berhasil persilangan atau seluruhnya letal. Kata kunci: cabai, dialel , genotipe introduksi, waktu persilangan
